Ridgeline Alteration Permit, Hillside Development Review Permit, Development Review Permit, Architectural Design Review Permit, Oak Tree Permit, and Initial Study to improve and expand the existing Eternal Valley Memorial Park. The project site is bounded on the north by undeveloped land, on the east by the existing Eternal Valley cemetery grounds, on the south by the Needham Ranch fire station pad and helipad, and on the west by Needham Ranch Parkway. The project site is currently vacant and previously approved as cemetery use by the County of Los Angeles. This project proposes to grade a 13.6-acre area and develop it as cemetery grounds, including a new loop road, landscaping, as well as burial plots.

Additionally, the project would construct a new 3,665 square-foot mausoleum, with a capacity of 780 caskets, and would include a 260 square-foot room, with niches for urns, at the top of the existing cemetery. The project would cut and fill 92,600 cubic yards of earth, to be balanced on site, and would also remove and recompact 100,300 cubic yards of earth for remedial grading. The site is in the Open Space (OS) zone.

Based on the information contained in the Initial Study prepared for this project, and pursuant to the requirements of Section 15070 of the California Environmental Quality Act (CEQA), the City of Santa Clarita [ ] City Council [ ] Planning Commission [ ] Director of Community Development finds that the project as proposed or revised will have no significant effect upon the environment, and that a Mitigated Negative Declaration shall be adopted pursuant to Section 15070 of CEQA.

1.0 INTRODUCTION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 1 June 2022

1.0 INTRODUCTION
The purpose of this Initial Study/Mitigated Negative Declaration (IS/MND) is to disclose and evaluate the environmental impacts of Master Case 20-231, the Eternal Valley Memorial Park Expansion Project, to be located to the west of the existing Eternal Valley Memorial Park and Mortuary, in Santa Clarita, California, as described further in Section 3.0 Project Description, below.

LEGAL AUTHORITY
As lead agency, the City of Santa Clarita has prepared this Initial Study in accordance with the California Environmental Quality Act (CEQA) of 1970 (Public Resources Code 21000–21189) and relevant provisions of the CEQA Guidelines (California Code of Regulations, Title 14, Division 6, Chapter 3, Sections 15000–15387), as amended.

Initial Study. Section 15063(c) of the CEQA Guidelines defines an Initial Study as the proper preliminary method of analyzing the potential environmental consequences of a project. To paraphrase from this Section, the relevant purposes of an Initial Study are:
(1) To provide the Lead Agency with the necessary information to decide whether to prepare an Environmental Impact Report (EIR) or a Negative Declaration (ND); (2) To enable the Lead Agency to modify a project, mitigating adverse impacts before an EIR is prepared, thereby, enabling the project to qualify for an ND; and (3) To provide sufficient technical analysis of the environmental effects of a project to permit a judgment based on the record as a whole, that the environmental effects of a project will not have a significant effect on the environment that would necessitate an EIR.

Negative Declaration or Mitigated Negative Declaration. CEQA Guidelines Section 15070 states a public agency shall prepare a negative declaration or mitigated negative declaration for a project subject to CEQA when:
(a) The initial study shows that there is no substantial evidence, in light of the whole record before the agency, that the project may have a significant effect on the environment, or (b) The initial study identifies potentially significant effects, but:

1. Revisions in the project plans or proposals made by, or agreed to by the applicant before a proposed mitigated negative declaration and initial study are released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effects would occur, and

2. There is no substantial evidence, in light of the whole record before the agency, that the project as revised may have a significant effect on the environment.

An ND or Mitigated Negative Declaration (MND) may be used to satisfy the requirements of CEQA when a project would have no significant unmitigable effects on the environment.

2.0 FINDINGS OF THIS INITIAL STUDY
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 2 June 2022

2.0 FINDINGS OF THIS INITIAL STUDY
The impact analysis in this Initial Study demonstrates that with the incorporation of mitigation measures, the proposed project would have a less than significant impact on the environment with regard to all CEQA Environmental Checklist topics. For each topic addressed in Section 4.0, the impacts associated with development of this project have been determined to be “Less than Significant,” or “No Impact” with regulatory compliance. Thus, an MND may be issued.

3.0 PROJECT DESCRIPTION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 3 June 2022

3.0 PROJECT DESCRIPTION
The proposed Eternal Valley Memorial Park Expansion project (project) is proposed for a site located within the County of Los Angeles in the City of Santa Clarita (City), as shown on Figure 1, Regional Location Map. The Eternal Valley Memorial Park was founded in 1958, and the site is currently approximately 54.12 acres in size. The project site, including the existing Memorial Park and proposed expansion area, has a general plan land use designation of Open Space (OS) and is zoned OS. The existing Memorial park is accessed from Sierra Highway. The project is located west of the existing memorial park (or cemetery) grounds which are located along Sierra Highway between Newhall Avenue and the Needham Ranch Parkway in a setting planned for near-future development, as shown on Figure 2, Vicinity Map.

The project would require development approvals from the City to grade a portion of an 18.5-acre parcel (known as “Area 6” of the memorial park) and a portion (the mausoleum site) of the 54.12-acre parcel containing the existing memorial park. Area 6 is bounded on the north by undeveloped land, on the east by the existing Eternal Valley Memorial Park grounds, on the south by the future site of a Los Angeles County Fire Department (LACoFD) fire station and helipad, and on the west by Needham Ranch Parkway and industrial uses. The project is adjacent to, but not part of, the Center at Needham Ranch business park, for which an EIR was certified by the City Council under Master Case 99-264 on June 24, 2003.

The proposed project would expand the existing Eternal Valley Memorial Park into the project site, resulting in grading of the existing hillside, within a Ridgeline Protection Overlay Zone (100 feet from a significant ridgeline) to construct a new loop road, burial plots, and landscaping. The conceptual plan is shown on Figure 3, Site Plan. The project would establish approximately 15 new acres of memorial park inventory area within an approximately 17-acre project site, providing approximately 15,000 casketed burial spaces and 6,000 cremation inurnment spaces. The project would also construct a new 27.5-foot tall, 3,665 square-foot mausoleum at the top of the existing memorial park, with capacity for 780 caskets and 560 urn niches. The project grading consists of cut and fill of a total of 192,900 cubic yards of earth, including mass excavation and fill, over- excavation, and shrinkage, which would be balanced on site within the 17-acre area of grading. Installation of turf for burial grounds will occur over three (3) phases, with incremental installations every two to three years, and completion by 2040. The project also includes installation of a wall or fence along Needham Ranch Parkway, along with landscaping to create a buffer between the memorial park use and the industrial and fire station uses. The project site would be mainly accessed through internal memorial park roadways leading to Sierra Highway and construct a connection to an existing restricted access service road leading to Needham Ranch Parkway, for restricted existing and emergency access.

Following circulation of the draft NOI/MND, a written comment was received, as discussed in Section 7.0, Response to Comments. Corrections and additions are summarized in Section 8.0, Corrections and Additions. The Mitigation Monitoring Program is provided in Section 9.0, Mitigation Monitoring Program.

REQUIRED ENTITLEMENTS
The project is requesting the following approvals from the City under Master Case 20-231:
• Ridgeline Alteration Permit (RAP): A RAP is required because the project would grade within the Ridgeline Protection Overlay Zone of the existing, mapped Significant Ridgeline. • Hillside Development Review (Class IV) Permit (HDR): An HDR is required because the project site has an average cross-slope of greater than fifteen percent and because the project would cut and fill more than 1,500 cubic yards of earth on a natural slope greater than ten percent average. • Development Review Permit (DR): A DR is required to review the proposed development and site plan.

3.0 PROJECT DESCRIPTION

DETERMINATION: (To be completed by the Lead Agency)
On the basis of this initial evaluation:

I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared.

I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.

I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.

I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed.

I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, an EIR Addendum will be prepared.

I. AESTHETICS. Except as provided in
Public Resources Code Section 21099, would the
project:
a. Have a substantial adverse effect on a scenic
vista?
b. Substantially damage scenic resources,
including, but not limited to, trees, rock
outcroppings, and historic buildings, or other
locally recognized desirable aesthetic natural
feature within a city-designated scenic
highway?
c. In non-urbanized areas, substantially degrade
the existing visual character or quality of
public views of the site and its surroundings?
(Public views are those that are experienced
from publicly accessible vantage points). If the
project is in an urbanized area, would the
project conflict with applicable zoning and
other regulations governing scenic quality?
d. Create a new source of substantial light or
glare, which would adversely affect day or
nighttime views in the area?
e. Per the City of Santa Clarita Local Guidelines,
would the project result in changes to the
topography of a Primary or Secondary
Ridgeline?
Impact Analysis
a. Less than Significant Impact. A significant impact may occur if a proposed project would introduce incompatible visual elements within a field of view containing a scenic vista or substantially blocks views of a scenic vista. The project site is currently partially graded and sloping, with an area of hillsides.

The site is located adjacent to the west of the existing Eternal Valley Memorial Park, east of the Needham Ranch Industrial Park, a future fire station, and undeveloped OS, in the urban visual setting of Newhall. The site is not near an eligible or State-designated scenic highway,1 and the City does not locally-designate scenic highways. The project site is not visible from the nearest eligible scenic highway, Interstate 5 (I-5), from Interstate 210 (I-210) near Tunnel Station to State Route 126 near Castaic,2 which is approximately 1.4 miles to the south with an intervening ridgeline completely blocking views of the project site.

The City of Santa Clarita Conservation and OS Element designates a significant ridgeline a scenic resource within the project vicinity.3 The project would grade within a Ridgeline Protection Overlay Zone, the area 1 Caltrans, List of Eligible and Officially Designated State Scenic Highways, Accessed on January 25, 2022 at https://dot.ca. gov/-/media/dot-media/programs/design/documents/desig-and-eligible-aug2019_a11y.xlsx. 2 Caltrans, List of Eligible and Officially Designated State Scenic Highways, Accessed on January 25, 2022 at https://dot.ca. gov/-/media/dot-media/programs/design/documents/desig-and-eligible-aug2019_a11y.xlsx. 3 City of Santa Clarita, City of Santa Clarita General Plan Conservation and Open Space Element, June 2011.

within one hundred (100) feet vertical and one hundred (100) feet horizontal distance from a City-designated ridgeline.
4 Thus a RAP would be required. Approval of the RAP would require that the project would minimize the effects of grading to the extent practical to ensure that the character of the ridgeline is preserved and that not cause depreciation of the appearance of the ridgeline in the vicinity. The project would minimize the effects of grading to the extent practical to ensure that the character of the ridgeline is preserved and that not cause depreciation of the appearance of the ridgeline in the vicinity. With approval of the RAP, the City will assure that no significant impact would occur with regard to ridgelines. In addition, the project site is not visible from a scenic highway. Therefore, the project would have a less than significant impact to scenic vistas.

Mitigation Measures: No mitigation measures are required. b. No Impact. A significant impact would occur if scenic resources within a City-designated scenic highway would be damaged or removed by development of the proposed project. The City does not designate scenic highways. The project site is located approximately 1.4 miles away from I-5, the nearest State eligible highway5 and not visible from that scenic corridor. The project is not located in a designated historic district and does not contain rock outcroppings. As detailed in the Section IV., Biological Resources, there are three (3) City-protected trees to the north of the project, but these are outside the limits of project grading and therefore they would not be impacted or encroached upon. Further, the less than significant impact to the resources would not be discernable from the scenic highway. Therefore, the project would result in no impact to scenic resources within a scenic highway.

Mitigation Measures: No mitigation measures are required. c. Less than Significant Impact. A significant impact would occur if a proposed project introduced incompatible visual elements on the site or visual elements incompatible with the character of the area surroundings. Projects in urbanized/developed areas could have a significant impact if they conflicted with applicable zoning and other regulations governing scenic quality. The project is located in an area developed with memorial park, industrial, and residential land uses and would develop memorial park burial grounds and a mausoleum building. Views in the vicinity of the project site are largely constrained by the existing memorial park in the urban setting and would be compatible with the character of the area surroundings. The project would not conflict with applicable zoning and other regulations affecting scenic quality (such as those related to height and size) and would therefore have a less than significant impact.

Mitigation Measures: No mitigation measures are required. d. Less than Significant Impact. A significant impact would occur if a proposed project introduced a new source of substantial light or glare that would adversely affect day or nighttime views in the area.

The project would not add lighting in the vicinity of residential land uses. Substantial is typically caused by building façades with large expanses of glass. The only proposed building is a mausoleum, which would not include large glass areas capable of producing substantial glare and would be distant from off-site land uses with intervening topography. Therefore, impacts related to light or glare would be less than significant.

Mitigation Measures: No mitigation measures are required. 4 City of Santa Clarita, City of Santa Clarita Municipal Code, Title 17: Zoning, Section 17.38.070, Accessed on April 11, 2022 at https://www.codepublishing.com/CA/SantaClarita/html/SantaClarita17/SantaClarita1738.html#17.38.070 5 Caltrans, List of Eligible and Officially Designated State Scenic Highways, Accessed on January 25, 2022 at https://dot.ca. gov/-/media/dot-media/programs/design/documents/desig-and-eligible-aug2019_a11y.xlsx.

e. Less than Significant Impact. A significant impact would occur if the project would result in changes to the topography of a Significant Ridgeline. As discussed under Checklist Item I.a, the project would grade within the protected zone of a City-designated significant ridgeline, and thus an RAP would be required. Approval of the RAP would require that the project minimize the effects of grading to the extent practical to ensure that the character of the ridgeline is preserved and that not cause depreciation of the appearance of the ridgeline in the vicinity. In addition, this area would not be visible form a scenic highway, as discussed previously. Therefore, impacts to significant ridgelines would be less than significant.

Mitigation Measures: No mitigation measures are required.

II. AGRICULTURE AND FORESTRY
RESOURCES.
a. Would the project convert Prime Farmland,
Unique Farmland, or Farmland of Statewide
Importance (Farmland), as shown on the maps
prepared pursuant to the Farmland Mapping
and Monitoring Program of the California
Resources Agency, to non-agricultural use?
b. Would the project conflict with existing
zoning for agricultural use, or a Williamson
Act contract?
c. Would the project conflict with existing
zoning for, or cause rezoning of, forest land (as
defined in Public Resources Code section
12220(g)), timberland (as defined by Public
Resources Code section 4526), or timberland
zoned Timberland Production (as defined by
Government Code section 51104(g))?
d. Would the project result in the loss of forest
land or conversion of forest land to non-forest
use?
e. Would the project involve other changes in the
existing environment, which, due to their
location or nature, could result in conversion
of Farmland, to non-agricultural use or
conversion of forest land to non-forest use?
Impact Analysis
a-e. No Impact. The subject property is located in an area identified as “grazing land” on the Los Angeles County Important Farmland 2018 map prepared by the California Department of Conservation6 for the Farmland Mapping and Monitoring Program (FMMP), but it is not mapped as Prime Farmland, Unique Farmland, or Farmland of Statewide Importance. The site is not used for agricultural purposes, has no agricultural zoning, and is not in conflict with a Williamson Act contract. The subject property is not located within a national forest or on forest land. As such, the project would have no impact on agricultural or forestry resources.

Mitigation Measures: No mitigation measures are required. 6 California Department of Conservation, Division of Land Resource Protection, Los Angeles County Important Farmland 2018, Sheet 1 of 2, Accessed on January 20, 2022 at https://www.conservation.ca.gov/dlrp/fmmp/Pages/LosAngeles.aspx.

III. AIR QUALITY. Where available, the
significance criteria established by the applicable air quality management district or air pollution control
district may be relied upon to make the following
determinations. Would the project:
a. Conflict with or obstruct implementation of
the applicable air quality plan?
b. Result in a cumulatively considerable net
increase of any criteria pollutant for which the
project region is non-attainment under an
applicable federal or state ambient air quality
standard?
c. Expose sensitive receptors to substantial
pollutant concentrations?
d. Result in other emissions (such as those
leading to odors) adversely affecting a
substantial number of people?
e. Per the City of Santa Clarita Local Guidelines,
would the project exceed the most recent air
quality thresholds as determined by the South
Coast Air Quality Management District, as
published in its “Air Quality Analysis
Guidance Handbook”?
Impact Analysis
This analysis is based upon the project Air Quality and Greenhouse Gas Technical Report7 (Appendix B).

The project site is located in the South Central Coast Air Basin (the Basin) and is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). Air quality in the Basin is affected by the emission sources located in the region, as well as by a natural terrain barrier to emission dispersion north and east of the metropolitan Los Angeles area, a dominant on-shore flow, and atmospheric inversion.

Sources and health effects of various pollutants regulated by the SCAQMD are shown in Table III-1, Criteria Pollutants Summary of Common Sources and Effects. 7 Impact Sciences, Eternal Valley Project, Air Quality and Greenhouse Gas Emissions Technical Report, March 2022.

* Health effects from CO exposures occur at levels considerably higher than ambient. ** Ozone is not generated directly by these sources. Rather, chemicals emitted by these precursor sources react with sunlight to form ozone in the atmosphere.
*** The elderly and people with cardiovascular disease or chronic lung disease (such as bronchitis or emphysema) are most likely to experience these adverse effects.

Baseline Air Quality
The United States Environmental Protection Agency has set primary national ambient air quality standards (NAAQS) for ozone, carbon monoxide (CO), nitrogen dioxide (NO2), SO2, PM-10, PM-2.5, and lead (Pb).

Primary standards are those levels of air quality deemed necessary, with an adequate margin of safety, to protect public health. In addition, the State of California has established health-based ambient air quality standards for these and other pollutants, some of which are more stringent than the federal standards (California ambient air quality standards, or CAAQS). Table III-2, Federal and State Ambient Air Quality Standards, lists the current federal and State standards for regulated pollutants.

Data on existing air quality in the Los Angeles County portion of the South Coast Air Basin are available from the California Air Resources Board (CARB) as measured at monitoring locations throughout Los Angeles County. The monitoring station located closest to and most representative of air quality at the project site is the Santa Clarita-Placerita Monitoring Station at 22224 Placerita Canyon Road, approximately 1.52 miles to the northwest. The Santa Clarita-Placerita station monitors O3, NO2, CO, and PM10. Table III-3, Air Monitoring Station Ambient Pollutant Concentrations, summarizes the annual air quality data from 2018 – 2020 in the local airshed for the criteria pollutants of greatest concern in Los Angeles County. As the Santa Clarita-Placerita Monitoring Station does not report measurements of PM2.5, Table III-3 reports measurements for those pollutants measured at the nearest monitoring station reporting such measurements, which is located in Reseda at 18330 Gault Street in Los Angeles, approximately 11.24 miles south of the project site.

As shown in Table III-3, ozone concentrations in Santa Clarita exceeded the 8-hour State standard 52 days, 56 days, and 73 days in 2018, 2019, and 2020, respectively, and exceeded the 1-hour State standard on 21 days, 34 days, and 44 days in 2018, 2019, and 2020, respectively. The PM-2.5 levels (measured at the Reseda Monitoring Station) did not exceed the federal standard from 2016 through 2018. The PM-10 concentrations did not exceed the federal standard and exceeded State standards for one day in 2019.

Measurements of NO2 and CO from Santa Clarita did not exceed standards from 2018 through 2020.

Project Emissions Modeling
Air quality impacts were evaluated in accordance with the methodologies recommended by CARB and the SCAQMD. Where criteria air pollutant quantification was required, emissions were modeled using the California Emissions Estimator Model version 2020.4.0 (CalEEMod). CalEEMod is a statewide land use emissions computer model designed to quantify potential criteria pollutant emissions associated with both construction and operations from a variety of land use projects. The output reports produced using CalEEMod are included within Appendix B, Air Quality and Greenhouse Gas Emissions Technical Report. a. Less than Significant Impact. SCAQMD drafted the 2016 Air Quality Management Plan (AQMP).
8 The 2016 AQMP was developed in effort with CARB, SCAG, and the U.S. EPA to establish a program of rules and regulations to reduce air pollutant emissions to achieves CAAQS and NAAQS. The plan’s pollutant control strategies are based on SCAG’s 2016 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). While SCAG adopted the updated 2020-2045 RTP/SCS in September 2020, it has not been incorporated into an applicable air quality plan.

The proposed project will not result in an increase in the frequency or severity of an existing air quality violation, or cause or contribute to new violations, or delay the timely attainment of air quality standards or the interim emissions reductions specified in the AQMP, as discussed in Section III, b. below. The proposed project will not exceed the assumptions in the AQMP or increments based on the years of the project buildout phase, as the project would not increase the local population based on proposed land uses and is consistent with the land use designation in the City of Santa Clarita General Plan. Therefore, the proposed project would not exceed the population or job growth projections used by the SCAMQD to develop the 2016 AQMP. Impacts would be less than significant.

b. Less than Significant Impact. A significant impact may occur if a project adds a cumulative considerable net increase for a criteria pollutant for which the region is in federal or State nonattainment.

The following evaluation is based on the estimated project emissions output reports produced using CalEEMod, included in Appendix B, Air Quality and Greenhouse Gas Emissions Technical Report.

Construction Emissions Estimates
Construction activities would generate temporary air pollutant emissions associated with fugitive dust from soil disturbance, exhaust emissions from heavy-duty construction vehicles, and material delivery trucks, and emissions from application of materials such as asphalt and paints.

The project’s maximum daily pollutant emissions from construction activities as estimated by CalEEMod are shown in Table III-4, Maximum Daily Emissions (Construction). During construction, the contractors are required to comply with SCAQMD Rule 402 (Nuisance) and Rule 403 (Fugitive Dust), and Tule 1113 (Architectural Coatings) among others, which assist in reducing short-term construction-related air pollutant emissions. Rule 402 prohibits emissions that would cause a public nuisance, Rule 403 requires fugitive dust sources to implement best available control measures for all sources, and all forms of visible particulate matter are prohibited from crossing any property line, and Rule 1113 limits ROG content of architectural coatings.

As shown in Table II-4, the project’s temporary construction emissions would not exceed SCAQMD numerical thresholds. Construction emissions impacts would be less than significant, and no mitigation would be required.

Operational Emissions
CalEEMod was also used to estimate the project’s operational emissions. As the proposed infill project would expand an existing memorial park use, there would be no net increase in vehicle trips, 9 and therefore
the project would result in zero net new mobile source emissions, as shown in the CalEEMod output sheets provided as an attachment to the Air Quality and Greenhouse Gas Emissions Technical Report included as Appendix B of this IS/MND. Table III-5, Project-Related Operational Emissions, shows the estimated total emissions for the proposed project from energy sources such as offsite electricity generation, and area sources, such as use of landscaping equipment. The estimated emissions from mobile sources shown in Table III-5 are conservative, given that no net difference in vehicle trips would occur from the project. To determine whether a regional air quality impact would occur, the operational emissions were compared to the SCAQMD’s recommended regional thresholds for operational emissions. As shown in Table III-5, the project’s total emissions would not exceed SCAQMD thresholds of significance, and impacts would be less than significant, without the need for mitigation measures. 9 Clark & Green Associates, Eternal Valley Memorial Park Traffic Review, August 23, 2021.

Mitigation Measures: No mitigation measures are required. c. Less than Significant Impact. The proposed project could have a significant impact if it would expose sensitive receptors to substantial pollutant concentrations. Sensitive receptors are those most susceptible to respiratory distress, such as children, elderly, persons with existing respiratory problems. The nearest sensitive receptors are residents of the neighboring multifamily apartment complex located approximately 800(approximately 244 meters) north of the project site. To identify impacts to sensitive receptors, the SCAQMD recommends addressing LSTs for construction for the site receptor area (SRA) applicable to the project, in this case SRA 13 for the Santa Clarita Valley area. The SCAQMD’s methodology states that “off-site mobile emissions from the project should not be included in the emissions compared to LSTs.” Therefore, for purposes of the construction LST analysis, only emissions included in the CalEEMod “on-site” emissions outputs were considered. The nearest sensitive receptor to the project site is a multi-family apartment complex approximately 244 meters north. LST screening thresholds are provided for distances to sensitive receptors of 25, 50, 100, 200, and 500 meters. Therefore, LSTs for receptors located at 200 meters were conservatively utilized in this analysis.

As detailed above, the SRA for the LST is the Santa Clarita Valley area (SRA 13). LSTs apply to NO2, CO, PM10, and PM2.5. The SCAMQD produced look-up tables for projects that disturb areas less than or equal to 5 acres in size. The project area to be graded is approximately 17-acres, but as approximately 4 acres would be graded on a given day, an LST threshold for 4 acres was calculated using the SCAQMD Linear Regression Methodology used for the construction LST analysis. Table III-6, Local Significance Thresholds and Peak Daily Onsite Emissions (pounds/day) shows that the project would not exceed the applicable LST.

LST thresholds for 4-acres were calculated per SCAQMD Linear Regression Methodology.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 20 June 2022
Exhaust particulates emitted from diesel powered equipment contains carcinogenic compounds, or toxic air contaminants (TACs). As proposed memorial park expansion would not generate a substantial quantity of diesel truck trips during operations, any measurable diesel TAC emissions from the project would occur for only a brief period during construction activities that would require onsite use of heavy-duty equipment.

Health risk analyses are typically assessed over a 9-, 30-, or 70-year timeframe rather than a relatively brief construction period, due to the lack of health risk associated with such a brief exposure. As such, potential impacts of the project due to emissions of TACs would be less than significant.

Areas with high vehicle density, such as congested intersections, have the potential to create high concentrations of CO, known as CO hotspots. According to the SCAQMD CEQA Air Quality Handbook, a potential CO hotspot may occur at any location where the background CO concentration already exceeds

9.0 ppm, the CAAQS for 8-hour for CO. Within the most recent three years for which measurements are available, the highest CO concentration at the Santa Clarita-Placerita station was measured at 1.2 ppm in 2019 and thus a CO hotspot would not occur. Based on the analysis above, the project’s potential to expose sensitive receptors to substantial pollutant concentrations would be less than significant.

Mitigation Measures: No mitigation measures are required. d. Less than Significant Impact. The proposed project could have a significant impact if it would create objectionable odors affecting a substantial number of people. The SCAQMD CEQA Air Quality Handbook (1993) identifies certain land uses as sources of odors. These land uses include agriculture (farming and livestock), wastewater treatment plants, food processing plants, chemical plants, composting facilities, refineries, landfills, dairies, and fiberglass molding. The proposed project would not include any of the land uses that have been identified by the SCAQMD as odor sources. Construction activities associated with the proposed project may generate detectable odors from heavy- duty equipment exhaust and architectural coatings. However, the nearest sensitive receptor is 700 feet away and construction-related odors would be short- term in nature and cease upon project completion The proposed project would be required to comply with the California Code of Regulations, Title 13, sections 2449(d)(3) and 2485, which minimizes the idling time of construction equipment either by shutting it off when not in use or by reducing the time of idling to no more than five minutes. This would reduce the detectable odors from heavy-duty equipment exhaust. The proposed project would also be required to comply with the SCAQMD Rule 1113 – Architectural Coating, which would minimize odor impacts from ROG emissions during architectural coating. Any odor impacts to existing adjacent land uses would be short-term and not substantial. As such, the project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people. Impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. e. Less than Significant Impact. As discussed under Threshold 3.3(b), the project would not exceed the SCAQMD thresholds for construction and operational emissions of criteria pollutants and therefore impacts would be less than significant.

Mitigation Measures: No mitigation measures are required.

Impact Analysis
This analysis is based upon the project Biological Resources Assessment Report10 (Appendix C-1) and Updated Biological Inventory for Extended Grading Area Report11 (Appendix C-2). An Oak Tree report (Appendix D) was also utilized in this analysis.
12 a. Potentially Significant Unless Mitigation Incorporated. A significant impact may occur if the project would result in a substantial adverse effect on any species identified as a candidate, sensitive or special-status species in local or regional plans. The partially-graded project site consists of undeveloped land.

Records of documented occurrences of State or federal endangered species identified in the Endangered Species Acts, as well as certain species of special concern designated by the California Department of Fish and Wildlife (CDFW) or U.S. Fish and Wildlife Service (USFWS), have been inventoried in the California Natural Diversity Database (CNDDB), which is maintained by the CDFW. The CNDDB was queried for the U.S. Geological Survey (USGS) 7.5-minute Oat Mountain quadrangle region containing the project site and five surrounding quadrangles and around the project site. The CNDDB, as well as California Native Plant Society (CNPS), literature search results are provided in Appendix C-1. No species listed as Endangered, Threatened, California Fully-Protected, or as a California Species of Special Concern have been observed at the project site. The site provides a small area suitable habitat for the California Gnatcatcher (Polioptila californica) CDFW Species of Special Concern, Federally Endangered and mitigation measure (MM) BIO-1 through MM BIO-4 would be implemented to reduce adverse effects on this species and other special status species to be less than significant. The site also provides some limited suitable habitat for other species identified in the query results, and with mitigation, a less than significant adverse effect on these species is anticipated. The project would result in no impact on candidate, sensitive, or special-status species in local or regional plans, policies, or regulations by the CDFW or USFWS.

Ground and vegetation disturbing activities, if conducted during the nesting bird season (February 1 to August 31), would have the potential to result in removal or disturbance to vegetation that could contain 10 CJ Biomonitoring, Eternal Valley Cemetery Biological Assessment Report, May 9, 2022. 11 CJ Biomonitoring, Eternal Valley Cemetery Biological Inventory for Extended Grading Area, June 23, 2021. 12 Arborgate Consulting Inc., Eternal Valley Memorial Park Expansion Oaks Revised Report, April 1, 2022.

active bird nests. Nesting birds may be disturbed by project-related noise, lighting, dust, and human activities, which could result in nesting failure and the loss of eggs or nestlings. Project activities resulting in the loss of bird nests, eggs, and young, could violate California Fish and Game Code sections 3503 (any bird nest), 3503.5 (birds-of-prey), or 3511 (Fully Protected birds). In addition, removal or destruction of one or more active nests of any other birds listed by the federal Migratory Bird Treaty Act of 1918 (MBTA), whether nest damage was due to vegetation removal or to other construction activities, would be considered a violation of the MBTA and California Fish and Game Code Section 3511. The loss of protected bird nests, eggs, or young due to project activities would be a potentially significant impact. Therefore, implementation of MM BIO-1, requiring nesting bird surveys if project activities cannot feasibly avoid the breeding bird season, would reduce potentially significant impacts to less than significant.

Mitigation Measures:

MM BIO-1 Pre-Project Surveys for Special-Status Wildlife Species For each grading phase or vegetation clearance phase, prior to the commencement of ground or vegetation disturbing activities, including but not limited to grading and fuel modification, two (2) pre-project surveys for special-status wildlife species, including the California gnatcatcher (Polioptila californica), and species considered locally sensitive by the City of Santa Clarita shall be conducted by qualified biologist(s) to determine the presence/absence of these species at the site. The biologist(s) shall have the necessary handling permits to capture, temporarily possess, and relocate wildlife. The first survey shall be conducted within fourteen (14) days and the second survey shall be conducted within three (3) days of commencement of ground or vegetation disturbing activities. The pre-construction surveys shall incorporate appropriate methods and timing to detect these species, including individuals that could be concealed in burrows, beneath leaf litter, in trees, or in loose soil. If a special-status species is found, avoidance is the preferred mitigation option. If avoidance is not feasible, a relocation plan including, at a minimum, the timing and methods for capturing and releasing the animals shall be prepared and submitted to the City and CDFW for review and approval. The species shall then be captured and transferred to appropriate habitat and location where they would not be harmed by project activities, preferably to OS habitats in the vicinity of the project site. If a federally listed species is found, the USFWS shall also be notified. A letter report summarizing the methods and results of the surveys and relocation efforts, if applicable, shall be submitted to the City and CDFW prior to commencement of project activities.

MM BIO-2 Pre-Construction Nesting Bird Surveys During Nesting Bird Season For each grading phase or vegetation clearance phase, no earlier than 14 days prior to ground or vegetation disturbing activities that would occur during the nesting/breeding season of native bird species potentially nesting on the site (typically February 1 through August 31), a City-approved qualified biologist shall perform two (2) field surveys to determine if active nests of any bird species protected by the State or federal Endangered Species Acts, Migratory Bird Treaty Act, and/or the California Fish and Game Code Sections 3503, 3503.5, or 3511 are present in the disturbance zone or within 200 feet of the disturbance zone for songbirds or within 500 feet of the disturbance zone for raptors and special-status bird species. The second nesting bird survey shall be conducted within three days of the start of ground or vegetation disturbing activities. A letter report summarizing the methods and results of the surveys shall be submitted to the City and CDFW prior to commencement of project activities. In the event that an active nest is found within the survey area, site preparation, construction, and fuel modification activities shall

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 24 June 2022
stop until consultation with the City, and when applicable CDFW and USFWS, is conducted and an appropriate setback buffer can be established. The buffer shall be demarcated and project activities within the buffer shall be postponed or halted, at the discretion of the biologist, until the nest is vacated and juveniles have fledged, as determined by the biologist, and there is no evidence of a second attempt at nesting.

MM BIO-3 Marking of Work Area
For each grading phase or vegetation clearance phase, prior to all ground disturbing and construction activities, the Applicant shall demarcate the northern and northeastern project limits of disturbance with exclusionary fencing to prevent encroachment of project activities into adjacent native habitats and to dissuade wildlife from entering the construction area. The fencing shall be marked with highly visible flagging. Project personnel should stay within the designated work areas to the extent feasible. Work areas shall be marked for the duration of the rough grading of the project. Silt fencing shall be installed to ensure that no debris or dirt enters areas outside of the project area.

MM BIO-4 Retainer of a Biological Monitor
For each vegetation clearance phase or prior to the issuance of a grading permit for each grading phase, a qualified biologist shall be retained by the Applicant as the lead biological monitor subject to the approval of the City. That person shall ensure that impacts to all biological resources are minimized or avoided and shall conduct (or supervise) pre-project field surveys and routine monitoring for species that may be avoided, affected, or eliminated as a result of grading or any other site preparation activities. The lead biological monitor shall ensure that all surveys and monitoring activities are performed by qualified personnel (e.g. avian biologists for nesting bird surveys, bat specialists for bat surveys, etc.) and that they possess all necessary permits and memoranda of understanding with the appropriate agencies for the handling of potentially-occurring special-status species. The lead biological monitor shall also conduct a pre-project environmental education program for all personnel working at the site, which shall be focused on conditions and protocols necessary to avoid and minimize potential impacts to biological resources. The lead biological monitor shall also ensure that daily monitoring reports (e.g., survey results, protective actions, results of protective actions, adaptive measures, etc.) are prepared, and shall make these monitoring reports available to the City and CDFW at their request.

Mitigation Measures: No mitigation measures are required. b. Potentially Significant Unless Mitigation Incorporated. A significant impact may occur if the project would have a significant adverse effect on any sensitive natural communities identified in local or regional plans, policies, regulations or by CDFW or USFWS.

Part of the project site has been previously graded, and the site is also surrounded on three sides by existing and planned development. As reported in the Biological Assessment Report, the project site does not include any natural communities such as riparian habitat, oak woodlands, or wetlands, but does contain sage scrub,
13 and is therefore designated as gnatcatcher habitat by the City.14 Mitigation measures MM BIO1 through MM BIO-4 would mitigate potential impacts to gnatcatchers to a less than significant impact with mitigation.

A significant impact may occur if the project has a substantial adverse effect on federally protected wetlands or waters of the U.S. The site does not contain known waters or wetlands; and none are located nearby. No wetlands or jurisdictional features were identified within the property and no special status wetland species were observed onsite by the Biological Assessment Report. 15 As the project
site is not located within any natural wetlands marshes, vernal pools, or waters of the U.S., the project would not remove or otherwise impair such areas and would therefore result in no impact.

Mitigation Measures: No mitigation measures are required. d. Less than Significant Impact. A significant impact may occur if the project would substantially interfere with the movement of any native resident or migratory fish or wildlife species with established native resident or migratory wildlife corridors or impede the use of native wildlife nursery sites. A wildlife corridor contains physical connections that allow wildlife to move between areas of suitable habitat in both undisturbed landscapes and landscapes fragmented by urban development. The project is not within an area identified as important to wildlife movement, such as a regional-scale habitat linkage or a wildlife movement corridor, as discussed in the project Biological Assessment Report. Although the study area provides vegetative cover and native habitats suitable for the movement of a diversity of species, the proposed development will not have a negative effect on wildlife movement. There is OS to the east and north of the project site that would allow wildlife movement, as discussed in the project Biological Assessment Report. As the site is not located within a wildlife corridor and the project would not substantially interfere with migratory corridors or impede wildlife movement and the project would have a less than significant impact on native resident wildlife movement.

Mitigation Measures: No mitigation measures are required. e. Less than Significant Impact. A significant adverse effect could occur if a project were to cause an impact that is inconsistent with local regulations pertaining to biological resources, such as the City Oak Tree Preservation Ordinance.16 The Oak Tree Preservation Ordinance regulates tree protections, removal permitting, and replacements as applicable. The Tree Ordinance protects all species of oak (Quercus spp.) exceeding six (6) inches in circumference when measured at a point four and one-half (4 1/2) feet above the tree’s natural grade or, for those trees on properties occupied by a single-family residence, exceeding twelve and one-half (12 1/2) inches in circumference when measured at a point four and one-half (4 1/2) feet above the tree’s natural grade. The protected zone of protected trees is defined as an area within 5 feet of the dripline (the outermost edge of the canopy) of a tree and no less than 15 feet of the trunk, where work activates are strictly controlled.

No trees would be removed by the project. There are three oak trees to the north of the project site, two (2) scrub oaks (Quercus dumosa or Quercus berberidifolia) and one (1) coast live oak tree (Quercus agrifolia).

Of the three trees north of the project, the coast live oak tree (Quercus agrifolia) and one of the scrub oaks (Quercus dumosa or Quercus berberidifolia) are protected trees. The canopies of the trees are outside of the project’s limits of grading and disturbance.17 The oak tree report states that the oaks appear to be over 20 feet from the limit of grading, which would meet the City’s minimum clearance requirement of 15 feet.

The report recommends chain link fencing at the limit of grading to protect a 20-foot radius from the trunk, 15 USFWS National Wetlands Mapper – Accessed on February 18, 2020 at https://www.fws.gov/wetlands/data/mapper.HTML. 16 City of Santa Clarita, Municipal Code, Title 17, Chapter 51, Article 40, Oak Tree Preservation. 17 Arborgate Consulting Inc., Eternal Valley Memorial Park Expansion Oaks Revised Report, April 1, 2022.

as standard regulatory compliance. Impacts would be less than significant and no mitigation measures would be required. In addition, the project landscaping would include the planting of approximately 37 new coast live oak trees (Quercus agrifolia) and approximately 45 new holly oaks (Quercus ilex).18 Mitigation Measures: No mitigation measures are required. f. No Impact. A significant impact would occur if the project would be inconsistent with mapping or policies of an adopted or approved conservation plan. The site is not located within an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan; therefore, the project would have no impact.

Mitigation Measures: No mitigation measures are required. g. No impact. As discussed in Threshold IV.e, there are three oak trees north of the project site. As shown on the project Grading Plan,19 the project would not be expected to encroach within 20 feet of any protected trees.
20 Therefore, the project would not result in the removal of a heritage oak tree or the removal of more than three oak trees and would have no impact. In addition, the oak trees would be protected by the protective fencing recommended in the oak tree report as a standard regulatory compliance measure, and the smaller scrub oak is not in good health or condition. Furthermore, the project landscaping would include the planting of approximately 37 new coast live oak trees (Quercus agrifolia) and approximately 45 new holly oaks (Quercus ilex).21
Mitigation Measures: No mitigation measures are required. h. No Impact. The project site would not result in disturbance of, or encroachment into, any river, river tributary, riparian habitat, stream or similar waterway identified on a United States Geologic Survey map as a “blue-line” watercourse, or any waterway otherwise identified as a significant resource by the City of Santa Clarita. As discussed under Threshold IV-b., the project site does not include any waterwayassociated natural communities such as riparian habitat, oak woodlands, or wetlands. Therefore, the project would have no impact to waterways or associated habitat.

Mitigation Measures: No mitigation measures are required. i. Less than Significant Impact. As discussed under Threshold IV-b., the project site contains sage scrub, which is designated as gnatcatcher habitat by the City, and contains approximately 3 acres of USFWS Critical Habitat for the coastal California gnatcatcher. However, the Critical Habitat designation does not affect purely private or State actions on private or State lands, nor require private or other non-federal lands to be managed for conservation. USFWS classifies the coastal California gnatcatcher as Threatened, the CDFW classifies it as a California Species of Special Concern, and it is federally endangered. Mitigation measure MM BIO-2 includes pre-construction surveys that would ensure that no gnatcatchers are present during project construction. Therefore, impacts would be less than significant with mitigation.

Mitigation Measures: No additional mitigation measures are required. 18 Clark & Green Associates, Preliminary Landscape Plan, September 30, 2021. 19 Hunsaker & Associates Los Angeles, Inc.

Impact Analysis
This analysis is based on a Phase I Archeological Resources Assessment23 of the project site prepared by ArcheoPaleo Resource Management, Inc., March 2022, (Appendix E) that included a record search from the South Central Coastal Information Center (SCCIC) and California Native American Heritage Commission (NAHC), a review of historic maps and aerial images, and a pedestrian survey of the subject property.
a. No Impact. A project would have a significant impact if it would cause a substantial adverse change in the significance of a historical resource as defined in CEQA Section 15064.5, which defines criteria for historical resources. The Cultural Resources Phase I Assessment involved a SCCIC record search of the subject property plus a 0.25-mile radius surrounding the subject property (combined, the “study area”). The results of the SCCIC record search found no previously identified cultural resources within the boundaries of the subject property. The results of the SCCIC record search found a previously identified historic structure (P-19- 186861) and two cultural resource reports (LA-02317 and LA-03829) within the study area. The historic structure is outside the project site and would not be affected by the project, and the cultural resources are not within the project site. Examination of these cultural resources reports, entitled “A Class I Cultural Resources Investigation for the Proposed Elsmere Canyon Solid Waste Management Facility, Newhall, Los Angeles County, California” by Jeanette A. McKenna and “Archaeological Reconnaissance Report: Tanbark Fuelbark, LA County” by Neil Metcalf, did not document cultural resources that would be directly or indirectly affected by the proposed project. No additional cultural resource reports dealt with either the development footprint or the 0.25-mile portion of the project study area.

On October 18, 2020 and June 15, 2021, ArchaeoPaleo Resource Management, Inc. performed pedestrian surveys of the partially graded, undeveloped site. Some areas of the site were covered in dense sagebrush scrub which prevented access. The findings were negative for cultural resources, but there exists a potential for uncovering unknown subsurface deposits during the project’s ground disturbance. No known historically significant buildings and properties have been identified within or adjacent to the project site.

Therefore, the project would result in no impact on a historical resource as defined in CEQA Section 15064.5.

Mitigation Measures: No mitigation measures are required. b. Potentially Significant Unless Mitigation Incorporated. A significant impact would occur if a known or unknown archaeological resource would be removed, altered, or destroyed as a result of the proposed development. A significant impact may occur if grading or excavation activities associated with a project would disturb archaeological resources that presently exist within the project site. Section 15064.5 of the CEQA Guidelines defines criteria for determining the significance of cultural resources.

The pedestrian surveys of the site on October 18, 2020 and June 15, 2021, were negative for archaeological resources on the ground surface. The results of the SCCIC record search found no previously identified cultural resources within the boundaries of the subject property. A request for a sacred lands file search and Native American contacts list was sent to the NAHC. The NAHC results were negative for Native American sites within the direct project area, but four responses were received from the contact list and the project site is near the approximate locations of two previously existing Native American villages. While there are no known prehistoric archaeological resources on the project site, unknown prehistoric archaeological resources may be unexpectedly encountered during ground disturbing activities considering the potential proximity to previously existing Native American villages.

In accordance with the federal, State, and local guidelines, including those set forth in the California Public Resources Code (PRC) Section 21083.2, if archaeological resources are discovered during excavation, grading, or construction activities, work shall cease in the area of the find until a qualified archaeologist has evaluated the find. These regulatory requirements prohibit personnel from collecting or moving any archaeological materials and associated materials discovered during excavation, grading, or construction activities. Construction activity may continue unimpeded on other portions of the project site. PRC Section 21083.2 requires found deposits to be treated in accordance with federal, State, and local regulations.

Mitigation Measure (MM) CUL-1 establishes a discovery protocol if potentially significant intact deposits are encountered during excavation. Implementation of MM CUL-1, which requires protective protocols be enacted if significant archaeological materials are recovered in native original context, would assure impacts to potentially present archaeological resources would remain less than significant.

Mitigation Measures:

MM CUL-1 Archaeological Monitoring
Prior to the commencement of construction, a qualified archaeologist shall create a separate Worker’s Environmental Awareness Program pamphlet that will be provided as training to construction personnel to understand regulatory requirements for the protection of cultural resources. This training shall include examples of cultural resources to look for and protocols to follow if discoveries are made. The archaeologist shall develop the training and any supplemental materials necessary to execute said training.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 30 June 2022
If an archaeological resource is encountered during construction when a monitor is not on site, all construction shall cease within at least 50 feet of the discovery and the Principal Investigator and Lead Archaeologist must be notified. Work cannot resume in the direct area of the discovery until the it is assessed by the Principal Investigator and/or Lead Archaeologist and indicates that construction can resume.

If an archaeological discovery cannot be preserved in situ and requires an excavation team or requires additional time to collect cultural resources, a Discovery and Treatment Plan (DTP) will be developed and the area will be cordoned off and secured so that an archaeological resources excavation team, led by the Principal Investigator and Lead Archaeologist, may recover the cultural resources out of that contained area. Once the Principal Investigator has determined that the collection process is complete for a given area or locality, construction activity will resume in that localized area. If human remains are encountered at any point during project construction, the local Native American most likely descendent (MLD) must be notified if not already on site and the procedures dictated by law must be implemented.

The Lead Agency and project proponent shall, in good faith, consult with the Fernandeño Tataviam Band of Mission Indians on the disposition and treatment of Tribal Cultural Resources encountered during Project implementation.

All significant cultural resources collected will be prepared in a properly equipped laboratory to a point ready for curation. Following laboratory work, all cultural resources will be identified, catalogued, analyzed, and delivered to an accredited museum repository for permanent curation and storage. Any cultural resources collected shall be donated to a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County. Accompanying notes, maps, and photographs shall also be filed at the repository. The cost of curation is assessed by the repository and is the responsibility of the project proponent. At the conclusion of laboratory work and museum curation, a final report will be prepared describing the results of the cultural mitigation monitoring efforts associated with the project. The report will include a summary of the field and laboratory methods, an overview of the cultural background within the project vicinity, a list of cultural resources recovered (if any), an analysis of cultural resources recovered (if any) and their scientific significance, and recommendations. A copy of the report will also be submitted to the designated museum repository (if applicable). c. Potentially Significant Unless Mitigation Incorporated. A significant impact would occur if previously interred human remains would be disturbed during excavation of the project site. The results of the SCCIC, and NAHC record searches were negative for cultural resources within the project property, but positive within the study area. While the existing memorial park is adjacent to the east, the project site has not been used as part of the formal memorial park, or a place of human internment, burial grounds, or burial site. However, there is a possibility that human remains can be unexpectedly encountered during ground disturbing activities. In addition, in the vicinity of a memorial park, there is a possibility of historical interment of human remains outside the perimeter of the memorial park grounds, and therefore there is an increased likelihood of encountering unexpected human remains within 50 feet of the existing memorial park grounds. If human remains are encountered unexpectedly during ground disturbing activities, regulatory requirements specified in State Health and Safety Code Section 7050.5 require that no further disturbance occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to PRC Section 5097.98. If human remains of Native American origin are discovered during construction, compliance with State laws, which fall within the jurisdiction of the NAHC (PRC Section 5097) relating to the disposition of Native American burials must be adhered to. MM CUL-2 establishes a discovery protocol for inadvertent discovery of human remains. With implementation of MM CUL-2, no impacts with regard to the inadvertent discovery of human remains would be less than significant.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 31 June 2022
Mitigation Measures:

MM CUL-2 Inadvertent Discovery of Human Remains
In the event of Native American human remains being inadvertently uncovered during project construction, the project proponent would immediately cease activity in the vicinity of the discovery and notify the local Native American MLD if not already on site and the procedures dictated by law must be implemented.

The inadvertent discovery of human remains is always a possibility during ground disturbances; State of California Health and Safety Code Section 7050.5 addresses these findings. This code section states that in the event human remains are uncovered, no further disturbance shall occur until the County Coroner has made a determination as to the origin and disposition of the remains pursuant to California PRC Section 5097.98. The Coroner must be notified of the find immediately, together with the City and the property owner.

If the human remains are determined to be prehistoric, the Coroner will notify the NAHC, which will determine and notify a MLD. The MLD shall complete the inspection of the site within 48 hours of notification and may recommend scientific removal and nondestructive analysis of human remains and items associated with Native American burials and an appropriate re-internment site.

The City, as Lead Agency, and a qualified archaeologist shall also establish additional appropriate mitigation measures for further site development, which may include additional archaeological and Native American monitoring or subsurface testing.

24 provided in Appendix B and the Fuel Consumption by
Construction Phase Worksheet,
25 provided by Appendix F, Fuel Consumption by Construction Phase Worksheet.
a. Less than Significant Impact. A significant impact would occur if a project would result in wasteful, inefficient, or unnecessary consumption of energy resources during construction or operation.

Construction
During construction, the project would use heavy-duty equipment for demolition, grading, paving, architectural coating, and building. Construction also involves trucks for material and supplies delivery, as well as powered hand tools. The majority of the equipment would likely be diesel-fueled. Smaller equipment, such as welders and pumps, may be electric-, gasoline-, or natural gas-fueled. The California Code of Regulations (CCR), requires drivers of diesel-fueled commercial motor vehicles with gross vehicle weight ratings greater than 10,000 pounds not to idle the vehicle’s primary diesel engine longer than five minutes at any location.26 Compliance with this regulation would also result in efficient use of constructionrelated energy and prevent unnecessary consumption of energy from diesel fuel.

According to carbon dioxide (CO2) emission factors for transportation fuels published by the U.S. Energy Information Administration, burning one gallon of diesel fuel generates approximately 22.4 pounds of CO2 and burning one gallon of petroleum-based gasoline produces approximately 19.6 pounds of CO2. 27 Based
on these emission factors, Table VI-1, Total Fuel Consumption During Construction, provides estimated CO2 emissions from the project consumption phase. 24 Impact Sciences, Air Quality and Greenhouse Gas Emissions Technical Report, March 2022. 25 Envicom Corporation, Fuel Consumption by Construction Phase Worksheet, April 2022. 26 California Code of Regulations, Section 2485, Airborne Toxic Control Measure to Limit Diesel-Fueled Commercial Motor Vehicle Idling. 27 U.S. Energy Information Administration, Environment Carbon Dioxide Emissions Coefficients, February 2, 2016.

As shown in Table VI-1, based on U.S. Energy Information Administration fuel consumption factors and the estimated “total CO2” emissions from the CalEEMod output sheets, project construction would consume a total of approximately 50,732 gallons of diesel fuel and approximately 6,412 gallons of gasoline. In 2018,

14.2 billion gallons of gasoline were sold in California28 and in 2018, 4.2 billion gallons of diesel, including off-road diesel, was sold in California.29 Assuming similar (or likely higher) gasoline and diesel fuel usage as in those years, the project construction fuel usage would be a small percentage of the State-wide usage.

Adherence to CCR Section 2485 and CARB anti-idling regulations for off-road diesel-fueled fleets would reduce the potential for wasteful or inefficient use of energy by construction equipment. Due to the temporary duration of construction and the necessity of fuel consumption inherent in construction, fuel consumption would not be excessive or substantial with respect to fuel supplies. The energy demands associated with fuel consumption during construction is typical for developments of similar size and would not necessitate the construction of additional energy facilities or distribution infrastructure. Therefore, project construction would not result in wasteful, inefficient, or unnecessary consumption of energy resources, and construction impacts would be less than significant.

Operations – Electricity
Project energy usage during operations would be minimal and associated with the mausoleum building, lighting, and landscaping. The project would not construct inhabited buildings and the only structure would be a mausoleum. As CalEEMod does not include a mausoleum land use, this portion of the project was modeled as a place of worship land use, resulting in conservatively high estimates for operational emissions.

The project would generate additional demand for electricity from the Southern California Edison (SCE).

As conservatively estimated by CalEEMod, the proposed project’s increase in electricity demand would be approximately 39,942 kilowatt-hours a year (kWh/year). According to the California Energy Commission, Los Angeles County (including the City of Santa Clarita) consumed 65,649,878,013 kWh of electricity in 2020.
30 The increase in demand would represent approximately 0.00006 percent (less than one millionth) of the yearly electricity demand, a negligible increase in relation to the entire County’s electricity demand.

Therefore, the project would not result in a significant environmental impact due to the project-related increase in electricity demand.

In addition, the project would be required to comply with applicable portions of the California Energy Code and California Green Building Standards Code (Title 24 of the California Code of Regulations) in effect at the time of building permit issuance, which establish standards for sustainable site development, energy 28 California Energy Commission, California Gasoline Data, Facts, and Statistics, Accessed March 7, 2021 at:

efficiency, water conservation, and material conservation. SCE has increased renewable energy through active procurement of renewable resources included in the Renewable Portfolio Standard and Pathway 204 specifies a pathway for providing reliable and sustainable electricity use to customers through 2045. 31 The
project would be designed to meet or exceed all City Building Code and Title 24 requirements which require energy efficient design materials. By compliance with applicable regulations and continued energy efficient programs implemented by SCE, the project would not result in wasteful or inefficient use of electricity energy supplies and impacts would be less than significant.

Operations - Natural Gas
The project would generate additional demand for natural gas from the Southern California Gas Company.

The project’s increase in natural gas demand would be approximately 180.3 kilo British-thermal unit per year (KBTU/year) as conservatively estimated by the above-referenced CalEEMod results. The CalEEMod results are conservative, as the project would not construct inhabited buildings and is unlikely to use any natural gas. According to the California Energy Commission, Los Angeles County (including the City of Santa Clarita) consumed 2,936.7 million therms or 293,598,229,310 KBTU/year of natural gas in 2020. 32 The project’s net increase in demand represents approximately 0.00000006 percent (less than one billionth) of the natural gas consumption in Los Angeles County in 2020, a negligible amount relative to Countywide consumption. Therefore, the project would not result in wasteful or inefficient use of natural gas energy supplies, and impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A significant impact may occur if a project would conflict with or obstruct a State or local plan for renewable energy or energy efficiency. As a regulatory requirement of the City Department of Building and Safety review process, the project would be reviewed for consistency with applicable State and local plans for renewable energy and efficiency. The applicable State standard is the CALGreen Code Title 24 standards, which requires projects to provide energy saving features, establish minimum standards for energy efficient construction practices, and increased energy efficiency. The project would be built to the code standards in effect at the time of permit issuance, which are generally more energy conserving over time. Project energy usage would be minimal, associated with the mausoleum building, lighting, and landscaping. As the project would comply with regulatory requirements and include energy efficient design features, the project would not conflict with or obstruct a State or local plan for renewable energy or energy efficiency, impacts would be less than significant.

Impact Analysis
This analysis is based largely on a Geotechnical & Geological Investigation33 report dated July 26, 2021 and prepared by Geotechnical Soilutions, Inc., (provided in Appendix G) and a Soils Investigation34 report dated October 14, 2019 prepared by John R. Byerly Incorporated (provided in Appendix H). a. i. Less than Significant Impact. A significant impact may occur if the project would directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault.

According to the California Department of Conservation’s California Earthquake Hazards Zone Application ("EQ Zapp"), there are no State-designated Alquist-Priolo Earthquake Fault Zones or active faults within the project site.
35 However, the project site is within the seismically active southern California region and could experience ground shaking in the event of a nearby earthquake. According to the Soils Investigation, the project is located approximately 1.1 miles from the Sierra Madre fault zone.36 As the potential for surface rupture of a known earthquake fault is low, and the City will require the construction of the project mausoleum to meet the latest building codes, the project would have a less than significant impact.

Mitigation Measures: No mitigation measures are required. a. ii. Less than Significant Impact. A significant impact may occur if the project would directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving strong seismic ground shaking. As noted in response to Checklist Question VII.a, with all of southern California, the site is in a seismically active area. The site and area have experienced historic earthquakes from various regional faults. Also as noted above, there are no State-designated Alquist-Priolo Earthquake Fault Zones or active faults within the project site.37 According to the Soils Investigation, the project is located approximately 1.1 miles from the Sierra Madre fault zone. 38 Because the project site does not
contain known active or potentially active faults and is not within an earthquake fault zone, the potential for fault rupture throughout the site is considered very low; however, the site may be subject to strong ground shaking during potential seismic activity from nearby faults. Given the proposed memorial park use, which is a largely outdoor use, potential impacts of strong seismic ground shaking are not expected to be substantial. Hazards associated with ground shaking can be reduced if the proposed mausoleum structure is designed and constructed in conformance with current building codes and engineering practices. Design and code compliance to be confirmed by the City Department of Building and Safety at plan check would ensure the project implements the recommendations provided in the Geotechnical & Geological Investigation and Soils Investigation, reducing potential seismic ground shaking impacts to less than significant.

a. iii. Less than Significant Impact. A significant impact may occur if the project would directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving seismic-related ground failure, including liquefaction.

Liquefaction is a phenomenon in which loose, saturated, relatively cohesionless soil deposits lose shear strength during strong ground motions. Liquefaction factors include intensity and duration of ground motion, gradation characteristics of the subsurface soils, in-situ stress conditions, and the depth to groundwater. Liquefaction is typified by a loss of shear strength in the liquefied soil layers due to rapid increases in pore water pressure generated by earthquake accelerations. As shown on EQ Zapp, the project site is not located within a liquefaction zone.39 According to the Geotechnical Investigation for the project, the soils on the project site included undocumented fill soil from the construction of existing areas of the memorial park.
40 The fill deposits are up to 69 feet thick and generally consist of silty sand with varying amounts of fine to coarse gravel and cobbles.
41 The fills were generally placed over native residual soil and colluvium and subsurface investigation encountered sandstone and conglomeratic sandstone generally consistent with the published geologic maps.42 Based on these sources, due to the lack of liquefaction potential at the site, liquefaction impacts would not be anticipated at the site.

Due to the project’s location in a seismically active area, like all of southern California, the project would require review through the plan check process to ensure project compliance with applicable building code requirements. Therefore, with regulatory compliance, impacts to seismic-related ground failure would be less than significant.

Mitigation Measures: No mitigation measures are required. a. iv. Less than Significant Impact. A significant impact may occur if the project would directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving landslides.

The Geotechnical & Geological Investigation states that the project site is not within a zone requiring an evaluation of earthquake induced landslides.43 The Geotechnical & Geological Investigation provides recommendations for the grading of the proposed lawn burial sites and mausoleum building. With the incorporation of the recommendations of the Geotechnical & Geological Investigation into the project as a part of the regulatory review process and a project feature. Therefore, impacts related to landslides would be less than significant and mitigation measures would not be required.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A significant impact may occur if the project would result in substantial soil erosion or the loss of topsoil.

After proposed grading, the proposed lawn burial areas would be hydroseeded and stabilized until turf is installed. The proposed lawn burial areas would be covered in grass and the project would implement the Geotechnical & Geological Investigation recommendation (as a part of the regulatory review process and 39 California Department of Conservation, Earthquake Hazards Zone Application (EQ Zapp), Earthquake Zones of Required Investigation, Accessed January 25, 2022 at https://www.conservation.ca.gov/cgs/geohazards/eq-zapp. 40 Geotechnical Soilutions, Inc., Geology, Geotechnical & Geological Investigation for Proposed Lawn Burial Areas, West and Southeast of Memorial Park (Known as Areas 6 W/ Loop Road & 7) Eternal Valley Memorial Park Santa Clarita California, July 26, 2001. 41 Ibid. 42 Ibid. 43 Ibid.

project feature) that drainage be designed to prevent sheet flow over the slope surfaces using non-erodible drainage devices. Therefore, erosion impacts during operations would be less than significant.

Mitigation Measures: No mitigation measures are required. c. Less than Significant Impact. A significant impact may occur if the project is built on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse.

As discussed previously the project is not within a liquefaction zone, or within a zone requiring an evaluation of earthquake induced landslides. Lateral spreading on the ground surface during a seismic activity usually occurs along the weak shear zones within a liquefiable soil layer and has been observed to generally take place towards a free face (i.e. retaining wall, slope or channel) and to less extent on ground surfaces with a very gently slope. Due to the lack of liquefiable soil, lateral spreading is not likely to occur.

Subsidence occurs when a large portion of the land is displaced vertically, usually due to the withdrawal of groundwater, oil, or natural gas. The site is not located within an area of known ground subsidence and there is no extraction of groundwater, gas, oil, or geothermal energy is proposed. The Geotechnical & Geological Investigation found that because the existing memorial park fill is undocumented, slight settlement of lawn burial areas may occur, however the settlement would not be detrimental. In addition, settled graves would be repaired in compliance with CCR Title 16, Division 12: Funeral Regulations, Section 2333.b.7, which would require that settled graves and markers be refilled or reset annually or within 120 days of the memorial park becoming aware.44Therefore, there is little to no potential for significantly unstable soil at the project site, and with regulatory compliance to be confirmed during plan check, project impacts related to site stability would be less than significant.

Mitigation Measures: No mitigation measures are required. d. Less than Significant Impact. A significant impact may occur if the project is located on expansive soil, creating substantial direct or indirect risks to life or property. Expansive soils contain high amounts of clay particles that swell when wet and shrink when dry. Foundations constructed on these soils are subject to uplifting forces caused by the swelling. The Soils Investigation conveys the results of laboratory testing, which showed that on-site soils have a very low expansion index.45 The Geotechnical & Geological Investigation states that existing on-site soils are suitable for use as compacted engineered fill after removal of debris and approval of the geotechnical engineer. With implementation of the recommendations of the Geotechnical & Geological Investigation, to be confirmed by the City during plan check, the project would have a less than significant impact with mitigation regarding expansive soils.

Mitigation Measures: No mitigation measures are required. e. No Impact. A significant impact may occur if the project site contains soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater. The Los Angeles County Sanitation District currently serves the wastewater needs of the existing memorial park and would continue to do so. The project would not include inhabited buildings with fixtures that would generate wastewater, and the number of employees and visitors is not anticipated to change with the project. Employees and visitors would use the same existing facilities, if needed, elsewhere on the memorial park property. Wastewater would continue to be conveyed to the 44 California, Cemetery and Funeral Bureau, California Code of Regulations Title 26, Division 23: Funeral Regulations, March 1, 2016, Accessed on April 13 at https://www.cfb.ca.gov/laws_regs/ ccr_funeral_regs.pdf 45 John R.

Valencia Water Company for treatment. No septic tanks or alternative onsite wastewater disposal systems are proposed for the project area. Therefore, the project would have no impact regarding this issue.

Mitigation Measures: No mitigation measures are required. f. Potentially Significant Unless Mitigation Incorporated. Paleontological resources are fossilized remains of organisms from the geologic past and the accompanying geologic strata. The potential for fossils depends on the rock type exposed at the surface. Sedimentary rocks contain the bulk of fossils in the City, although metamorphic rocks may also contain fossils. Some of the project site has been previously disturbed, but the project would require new grading.

ArchaeoPaleo Resource Management, Inc.’s Phase I Archaeological Resources Assessment addressed the project’s potential to impact paleontological resources.46 Field reconnaissance of the project area yielded negative results for paleontological resources, but there still is the potential to uncover subsurface sites or features.47 The predominant rock and soil type underlying the surface of the project site is part of the 1.8- million-year-old marine deposit of Pliocene-Pleistocene age named the Saugus Formation, which is composed mostly of sandstone, conglomerate deposits, with rare occurrences of limestone and laminated mudstone. Sandstone layers within this formation are very rich in invertebrate fossils especially producing shallow-marine snails and clams. Vertebrate fossilized specimens of bison, mastodon, horse, deer, and a rare species of tapir have been uncovered within this formation at various depths. Although the field reconnaissance yielded negative results for paleontological resources, this does not preclude the possibility to uncover paleontological sites or fossil remains within the project area of disturbance, as there is potential for older alluvium and sediments from the fossiliferous Saugus Formation to be present at greater depths, which may yield significant fossil remains.

The Phase I Archaeological Resources Assessment recommended paleontological resources mitigation during project development. MM PAL-1, which establishes a discovery protocol in the event paleontological resources are encountered and requires paleontological monitoring where substantial project excavation occurs. Implementation of MM PAL-1 would ensure that the project’s potential paleontological resources impacts would be less than significant.

Mitigation Measures:

MM PAL-1 Paleontological Discovery Protocol
If potentially significant intact deposits are encountered that are within an undisturbed context, then a fossil “discovery” protocol will be followed, which will be developed prior to project grading. If project excavation is in native soil or bedrock, then a paleontological monitor should be on site to watch for fossil resources. Such monitoring will be outlined in the “discovery” protocol, developed prior to grading.

If significant prehistoric or larger fossil materials are recovered in native original context, then all work in that area shall be halted or diverted away from the discovery to a distance of 50-feet until a qualified senior archaeologist or paleontologist can evaluate the nature and/or significance of the find(s). If a senior archaeologist or paleontologist (not the field 46 ArchaeoPaleo Resource Management, Inc., Phase I Archaeological Resources Assessment for the Eternal Valley Memorial Park and Mortuary, City of Santa Clarita, Los Angeles County, California, February 2020, updated June 2021. 47 ArchaeoPaleo Resource Management, Inc., Phase I Archaeological Resources Assessment for the Eternal Valley Memorial Park and Mortuary, City of Santa Clarita, Los Angeles County, California, February 2020, updated June 2021.

monitor) confirms that the discovery is potentially significant, then the Lead Agency will be contacted and informed of the discovery.

Construction will not resume in the locality of the discovery until consultation between the senior archaeologist or paleontologist, the owner’s project manager, the City, and all other concerned parties, takes place and reaches a conclusion approved by the City. If a significant resource is discovered during earth-moving, complete avoidance of the find is preferred. However, if the discovery cannot be avoided, further survey work, evaluation tasks, or data recovery of the significant resource may be required by the City. The City may also require changes to the Monitoring Plan, based on the discovery, if fossil material is encountered.

All costs for the additional monitoring, discovery assessment, discovery evaluation, or data recovery of will be the responsibility of the applicant, within the cost parameters outlined under CEQA. All individual reports, including the final project Monitoring Report, will be submitted to the NHM at the conclusion of the project.
g. Potentially Significant Unless Mitigation Incorporated. A significant impact may occur if the project result in the movement or grading of earth exceeding 100,000 cubic yards. The project grading would consist of 192,900 cubic yards of earth, including mass excavation and fill, over- excavation, and shrinkage to be balanced on site. While there would be more than 100,000 cubic yards of grading, no soil import or export would be required, resulting in no truck hauling trips. As discussed under Threshold III.a., project construction-related impacts to air quality would be less than significant, and as discussed in Thresholds V.b., V.c., and V.f., the project construction-related impacts to cultural resources and paleontological resources would be less than significant with MM PAL-1. Therefore, the project would have a less than significant impact related to movement or grading of earth exceeding 100,000 cubic yards with mitigation.

Mitigation Measures: MM PAL-1, Paleontological Discovery Protocol, discussed in Section VII.f., is required. No further mitigation measures are required.

VIII. GREENHOUSE GAS EMISSIONS.

Would the project:

directly or indirectly, that may have a
significant impact on the environment?
b. Conflict with an applicable plan, policy or
regulation adopted for the purpose of
reducing the emissions of greenhouse gases?
Impact Analysis
This analysis is based upon the project Air Quality and Greenhouse Gas Technical Report (Appendix A).

Greenhouse gases (GHGs) can contribute to an increase in the temperature of the earth’s atmosphere by absorbing infrared radiation transmitted by the sun, thereby trapping and retaining heat within the atmosphere. Climate change is the observed increase in the average temperature of the Earth’s atmosphere and oceans over an extended period of time, as well as other associated changes in climate, such as substantial variations in wind patterns, precipitation, and the frequency and/or strength of storms.

The principal GHGs are: CO2, methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6), perfluorocarbons (PFCs), and hydrofluorocarbons (HFCs). Each GHG differs in its mass and ability to trap heat within the atmosphere based on factors such as capacity to directly absorb radiation, length of time in the atmosphere, and chemical transformations that create new GHGs. Because the warming potential of each GHG differs, GHG emissions are typically expressed in terms of CO2 equivalents (CO2e), providing a common expression for the combined volume and warming potential of the GHGs generated by an emitter.

Total GHG emissions from individual sources are generally reported in metric tons (MT) and expressed as metric tons of CO2 equivalents (MTCO2e).

State Assembly Bill (AB) 32, the Global Warming Solutions Act of 2006, established mandatory provisions and GHG reduction targets within specified time frames, including a requirement that California’s GHG emissions be reduced to 1990 levels by 2020. Senate Bill (SB) 32 requires the State to further reduce GHGs to 40 percent below 1990 levels by 2030. Executive Order S-3-05 aims to reduce statewide GHG emissions to 80 percent below 1990 levels by 2050.

The CARB in collaboration with over twenty State agencies issued a Final Scoping Plan in 2017 in order to set a framework for the State to meet the overall reduction goals set in SB 32. The 2017 Scoping Plan identified key sectors of the implementation strategy, which includes improvements in low carbon energy, industry, transportation sustainability, natural and working lands, waste management, and water. Through a combination of data synthesis and modeling, CARB determined that the target statewide 2030 emissions limit is 260 million MTCO2e, and that further commitments will need to be made to achieve an additional reduction of 50 million MTCO2e beyond current policies and programs. Key elements of the 2017 Update include a proposed 20% reduction in GHG emissions from refineries and an expansion of the Cap-andTrade program to meet the aggressive 2030 GHG emissions goal.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 42 June 2022
SCAQMD released draft guidance regarding interim CEQA GHG significance thresholds. In its October 2008 document, the SCAQMD proposed a 30% emission reduction target to determine significance for commercial/residential projects that emit greater than 3,000 metric tons per year. On December 5, 2008, the SCAQMD Governing Board adopted the staff proposal for an interim GHG significance threshold for stationary source/industrial projects where the SCAQMD is lead agency. However, SCAQMD has yet to adopt a GHG significance threshold for land use development projects (e.g., residential/commercial projects) and formed a GHG Significance Threshold Working Group to further evaluate potential GHG significance thresholds. The draft tier thresholds recommended by the SCAQMD Working Group were never authorized as guidance for GHG analyses. These recommended thresholds are over a decade old; as a result, these thresholds were not utilized in this analysis.

On September 3, 2020, the Southern California Association of Governments (SCAG) Regional Council unanimously voted to approve and fully adopt Connect SoCal (which is the official 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy [RTP/SCS]). Connect SoCal is a long-range visioning plan that includes a combination of transportation and land use strategies that outline how the region can achieve California’s GHG emission reduction goals and federal Clean Air Act requirements.

The locally adopted Climate Action Plan for GHG reduction is the August 2012 City of Santa Clarita Climate Action Plan, which is certified through 2020.
a. Less than Significant Impact. A significant impact would occur if the project would generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment.

The project’s annual GHG emissions from construction and operations were estimated using CalEEMod.

The CalEEMod output sheets can be found in the Attachment to the Air Quality and Greenhouse Gas Technical Report in Appendix B.

Construction
During construction, GHG emissions would be generated by use of heavy equipment, application of construction materials (e.g., asphalt, paints), and transportation of personnel and materials. Project construction activities emissions would be temporary and of short duration. The SCAQMD guidance document for GHG emissions analysis for construction recommends amortization of emissions over a 30- year project lifetime to evaluate significance on an annual basis. The project’s estimated generation of construction-related GHG emissions are shown in Table VIII-1, Construction Greenhouse Gas Emissions.

Note: Numbers may include rounding.

As shown in Table VIII-1, the total emissions resulting from construction would be 572.46 MTCO2e and the 30-year amortized emissions would be 19.08 MTCO2e. This amortized amount is added to the annual operational period emissions, evaluated below.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 43 June 2022
Operations
Operation of the proposed project would result in GHG emissions from onsite use of heating, ventilation and air conditioning equipment, and offsite sources such as electricity generation, water distribution and treatment, disposal of solid waste, and wastewater treatment. The project would not result in an increase in vehicle use during operations, and thus would have no net increase in mobile source GHG emissions from operations. The total operational emissions plus the annualized construction emissions from the project as estimated by CalEEMod are shown in Table VIII-2, Operational Greenhouse Gas Emissions.

a
Net mobile source emissions are zero as the project would have no change in visitors or employment.

As shown in Table VIII-2, with the addition of amortized construction emissions, the project’s total annual GHG emissions were estimated to be approximately 67.77 MTCO2e. The estimated annual operational GHG emissions from mobile sources shown in Table VIII-2 are conservative, given that the CalEEMod default trip generation rates were used, while no net difference in vehicle trips would occur from the project.

As such, the project’s total operational emissions of GHGs would be less than 67.77 MTCO2e. While these conservatively quantified emissions are far below the SCAQMD staff’s proposed numerical threshold of 3,000 MT of CO2e per year for evaluating GHG impacts of non-industrial projects. As discussed above, no applicable quantitative threshold has been adopted for evaluating the significance of the project’s impacts.

Therefore, this analysis will use a qualitative discussion of plan consistency to determine the potential significance of the Project’s contribution to global GHG emissions and resulting environmental effects pursuant to CEQA Guidelines Section 15064.4(a). The analysis of significance under CEQA is based on the project’s consistency with statewide and regional policies and plans to meet the State reduction goals set in SB 32, including CARB’s 2017 Scoping Plan and SCAG’s 2020 Connect SoCal RTP/SCS and the Santa Clarita General Plan. As discussed below under the response to Checklist Question VIII.b., the project would be consistent with these plans, and therefore, project GHG emission impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A significant impact would occur if the project conflicted with any applicable plan, policy, or regulation adopted for the purpose of reducing the emissions for GHGs.

As discussed in the Appendix A, the proposed project is consistent with and would not result in the generation of GHG emissions in the environment or conflict with the applicable plans, policies and regulation including AB 32, SB 32, the CARB 2017 Scoping Plan, SCAG’s RTP/SCS, and the Santa Clarita General Plan.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 44 June 2022
Consistency with AB 32 & SB 32
The proposed project would not conflict with applicable statewide regulatory programs designed to reduce GHG emissions consistent with AB 32 and SB 32. During construction, the project will utilize equipment in compliance with CARB requirements. Mobile sources during construction and operation would be subject to the requirements of California Assembly Bill 1493 (Pavley Standards), the Advanced Clean Cars Program, and the Low Carbon Fuel Standard Regulation. Additionally, the project would be designed, constructed, and operated consistent with California Title 24 and CALGreen (2019). These regulations require projects to comply with specific standards related to building energy efficiency and green building.

Consistency with the Final 2017 Scoping Plan Update
The project would not conflict with CARB’s Scoping Plan. The Scoping Plan (approved by CARB in 2008 and updated in 2014 and 2017) provides a framework for actions to reduce California’s GHG emissions and requires CARB and other state agencies to adopt regulations and other strategies to reduce GHGs. The Scoping Plan is not directly applicable to specific projects, nor is it intended to be used for project-level evaluations. However, under the Scoping Plan, there are several regulatory measures aimed at the identification and reduction of GHG emissions. CARB and other state agencies have adopted many of the measures identified in the Scoping Plan. Most of these measures focus on area source emissions (e.g., energy production, distribution and usage, and high-global warming potential GHGs in consumer products) and changes to the vehicle fleet (i.e., hybrid, electric, and more fuel-efficient vehicles) and associated fuels (e.g., Low Carbon Fuel Standard), among others. The 2008 Scoping Plan recommends strategies for implementation at the statewide level to meet the goals of AB 32 and establishes an overall framework for the measures that will be adopted to reduce California’s GHG emissions. The 2017 Scoping Plan Update reflects the 2030 target of a 40% reduction below 1990 levels codified by SB 32. The project would comply with all regulations adopted in furtherance of the Scoping Plan to the extent required by law and to the extent that they are applicable to the proposed project.

Consistency with SCAG’s Connect SoCal Plan
At the regional level, SCAG’s Connect SoCal RTP/SCS represents the region’s Climate Action Plan that defines strategies for reducing GHGs. In order to assess the project’s potential to conflict with the RTP/SCS, this section analyzes the project’s consistency with the policies of the RTP/SCS. Generally, projects are considered consistent with the provisions and general policies of applicable City and regional land use plans and regulations, such as SCAG’s current RTP/SCS, Connect SoCal, if they are compatible with the general intent of the plans and would not preclude the attainment of their primary goals.

As shown in Table VIII-3, Project Consistency with SCAG’s RTP/SCS, the Project would not conflict with the applicable strategies set forth in the RTP/SCS’s “A Path to Greater Access, Mobility, & Sustainability” chapter. Therefore, the Project would be consistent with the applicable GHG reduction related actions and strategies contained in Connect SoCal.

Because goals, objectives and policies approved under the General Plan are forecast to meet the GHG emission reduction targets mandated by AB 32, development projects that are able to demonstrate consistency with the General Plan and zoning ordinance will by association demonstrate consistency with the CAP.

The Project site is zoned OS and has a General Plan designation of OS. The proposed Project would be an expansion of the Eternal Valley Memorial Park and Mortuary into a currently vacant area. The proposed Project would include construction of a 3,665 square foot mausoleum, traditional lawn burial gardens, and a private cemetery loop road for access by cemetery visitors. As such, the Project would be consistent with the City’s General Plan and zoning designation for the site. Furthermore, the Project is consistent with the goals, objectives, and policies of the City’s General Plan.

Conclusion
As demonstrated above, the proposed Project is consistent and would not result in the generation of GHG emissions in the environment or conflict with the applicable plans, policies and regulation including the CARB 2017 Scoping Plan, SCAG’s RTP/SCS, and the Santa Clarita General Plan. As such, the proposed project would have a less than significant impact in regard to GHG emissions.

Mitigation Measures: No mitigation measures are required.

IX. HAZARDS AND HAZARDOUS
MATERIALS. Would the project:
a. Create a significant hazard to the public or the
environment through the routine transport, use,
or disposal of hazardous materials?
b. Create a significant hazard to the public or the
environment through reasonably foreseeable
upset and accident conditions involving the
release of hazardous materials into the
environment?
c. Emit hazardous emissions or handle hazardous
or acutely hazardous materials, substances, or
waste within one-quarter mile of an existing or
proposed school?
d. Be located on a site that is included on a list of
hazardous materials sites compiled pursuant to
Government Code Section 65962.5 and, as a
result, would it create a significant hazard to the
public or the environment?
e. For a project located within an airport land use
plan or, where such a plan has not been adopted,
within two miles of a public airport or public use
airport, would the project result in a safety
hazard or excessive noise for people residing or
working in the project area?
f. Impair implementation of or physically interfere
with an adopted emergency response plan or
emergency evacuation plan?
g. Expose people or structures, either directly or
indirectly, to a significant risk of loss, injury or
death involving wildland fires?
Impact Analysis
a. Less than Significant Impact. A significant impact may occur if the project would create a significant hazard to the public or the environment through the routine transport, use, or disposal of types of hazardous materials or quantities.

The memorial park uses associated with the proposed project would not involve any routine transport, use, or disposal of substantial amounts of hazardous materials. Occasional use of small amounts of hazardous materials would occur for landscaping, such as fertilizers, pesticides, herbicides, and for cleaning and maintaining the mausoleum building, such as household cleaners and paint. In addition, some of the interred human remains would contain formaldehyde or other substances used in embalming. These materials would be similar to those used for the other landscaped burial areas and buildings that currently exist in the memorial park. The project would comply with CCR Title 16, Division 12: Funeral Regulations, Section

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 49 June 2022
1222: Embalming Fluids, which prohibits the use of embalming fluid containing “heavy minerals or metallic substances which have a poisonous effect, such as arsenic, lead and mercury.”48 Accordingly, the project would have a less than significant impact with regard to creating a significant hazard through the routine transport, use, or disposal of hazardous materials.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A project may have a significant impact if the project would create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment.

Construction of the project would involve the use of hazardous materials necessary to construct a mausoleum and associated paved surfaces such as paint, but they will be properly stored in sufficiently small quantities to prevent a significant hazard to the public if they were released. During operation, as discussed above (in part “a”) in response to Checklist Question IX.a, the project would occasionally use small amounts of hazardous materials, but these would be used in insignificant amounts. Therefore, the project would have a less than significant impact with regard to a hazard involving the release of hazardous materials into the environment.

Mitigation Measures: No mitigation measures are required. c. No Impact. A significant impact may occur if the project would emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school. The proposed project would expand an existing memorial park and would be adjacent to the Needham Ranch Industrial Park and a new Los Angeles County Fire Station. The project site is not within one-quarter mile of a school; the nearest is the Dr. J. Michael McGrath Elementary School, which is approximately 0.7 miles away. Further, the amounts of hazardous materials to be used during construction and occasionally used during operations would be considered small. Therefore, the project would have no impact in regard to emitting hazardous emissions or substances within one-quarter mile of an existing or proposed school.

Mitigation Measures: No mitigation measures are required. d. No Impact. A significant impact may occur if the project is located on materials sites compiled pursuant to Government Code Section 65962.5 and as a result would create a significant hazard to the public or the environment. Based on a review of the State Water Resources Control Board’s GeoTracker database, related to Government Code Section 65962.5, the site is not associated with a cleanup site and is not within 1,000 feet of a cleanup site.49 The site is not associated with or located within 1,000 feet of a site listed on the Department of Toxic Substance Control (DTSC) EnviroStor database.50 Therefore, the project would not result in the creation of a significant hazard to the public or the environment as a result of previous uses being included in lists of hazardous materials sites compiled pursuant to Government Code Section 65962.5. No impact would occur.

e. No Impact. The nearest airport to the project site is Whiteman Airport in the community of Pacoima located approximately 8.56 linear miles southeast. The project site is not located within the Airport Influence Area of Whiteman Airport.
51 There are no airport-related building height restrictions on the site, the project would not place structures within a designated flight path. and the project would not result in a safety hazard to people working or residing within the project area regarding aircraft operations in the vicinity. Therefore, no impact would occur.

Mitigation Measures: No mitigation measures are required. f. Less than Significant Impact. A project would normally have a significant impact if the project would interfere with an emergency response plan or emergency evacuation plan. The project site is accessed by Sierra Highway, which is a public roadway that has two lanes in each direction and a median. The project would not increase the number of employees or visitors and therefore would not generate additional vehicle trips beyond existing conditions. As for the project itself, it would not inhibit any emergency access routes, as it would be fully contained on the project parcel. The project would require an internal loop road, which would connect in two places to the existing memorial park grounds internal driveway system, and a new connection to an existing access road connecting to Needham Ranch Parkway, but would not build new parking lots or affect connections to the existing external street network. The project would be subject to requirements and approval by the LACoFD. Therefore, neither the project construction nor operations would physically interfere with an adopted emergency response plan or emergency evacuation plan, and impacts would be less than significant.
g. Less than Significant Impact. A significant impact may occur if a project is located in proximity to wildland areas and would pose a potential fire hazard, which could affect persons or structures in the area in the event of a fire. The project is located in an urbanizing area where recent development of the Needham Ranch industrial park has reduced wildland areas. The project would be surrounded on three sides by existing and planned development: the existing portion of the memorial park to the east, the Needham Ranch industrial park to the west, and the future LACoFD station to the south. However, the land immediately to the north would remain undeveloped open space. The project site is located within land classified as a Very High Fire Hazard Severity Zone (VHFHSZ). 52 The proposed project site would
predominantly be a landscaped, irrigated memorial park area, and the proposed mausoleum structure would meet all the latest fire code requirements as discussed in response to Section XX., Wildfire. Therefore, impacts related to fire hazards would be less than significant.

Mitigation Measures: No mitigation measures are required. 51 County of Los Angeles, Airport Land Use Commission, Airports and Airport Influence Areas, August 18, 2018. 52 California Department of Forestry and Fire Protection, Very High Fire Hazard Severity Zones in LRA as Recommended by CAL FIRE: Santa Clarita, September 2011.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 52 June 2022
The project site currently consists of partially graded, undeveloped land. The project site currently has no impervious surfaces. The project would add some impervious surfaces for the proposed loop road and the mausoleum structure. However, the project would follow existing drainage patterns as shown on the Drainage Plans.
54 During construction, the project would be subject to compliance with the existing National Pollutant Discharge Elimination System (NPDES) Permit and follow guidelines within the Los Angeles County Department of Public Works Low Impact Development (LID) Standards Manual.

The project complies with Best Management Practices (BMPs) in the Los Angeles County Department of Public Works LID Standards Manual, the project would maintain water quality standards during construction. The project LID BMPs such as vegetated filter strip, turf, and/or planter vegetation discussed in the Project Drainage Plans, to be reviewed and approved by the Public Works Department, would assure water is contained and slowed to infiltrate the groundwater as much as possible, which reduces pollutants (total dissolved solids) entering the water stream and assures the volume of runoff leaving the site complies with the LID manual. With the vast majority of the site remaining as landscaped memorial area, substantial area will remain for stormwater infiltration. As such, the project would have a less than significant impact with regard to violating any State or federal water quality standards or waste discharge requirements.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. The project may have a significant impact if it would substantially decrease groundwater supplies or interfere with groundwater recharge such that the project may impede sustainable groundwater management of the basin.

The project would add some impervious surface area to a site without impervious surface. The project would follow guidelines within the Los Angeles County Department of Public Works LID Standards Manual, as discussed above. Runoff from the western portion of the project site would flow (as surface flow or through a swale) west into 24-inch storm drain inlets along Needham Ranch Parkway or debris basins that are planned as part of The Center at Needham Ranch industrial park and runoff from the eastern portion of the project would flow downhill, across the existing memorial park to the east, into the existing 24-inch storm drain inlet. At completion of the project, the project would follow existing drainage patterns within the site, consistent with the Drainage Plans, and would assure that stormwater is contained and slowed to infiltrate the groundwater, avoiding excessive offsite stormwater runoff, compliant with LID requirements. Therefore, the project would have a less than significant impact to groundwater supplies or recharge.

Mitigation Measures: No mitigation measures are required. c.i. Less than Significant Impact. A project would have a significant impact on surface water hydrology if it would substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river through the addition of impervious surfaces, in a manner which would result in substantial or erosion or siltation on site. The project site is located in an urbanizing area of the City and no streams or river courses are located on the subject property. The project would follow existing drainage patterns. Impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. c.ii. Less than Significant Impact. A project could have a significant impact if it would create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. The project would somewhat increase 54 Ibid.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 53 June 2022
impervious surfaces and would decrease the amount of vegetation on site that would slow surface water runoff. However, as stated above, the project would retain existing drainage patterns and the LID regulations, to be reviewed and approved by the Public Works Department, would assure no increase in runoff. Therefore, the project would have a less than significant impact with regard to increasing the rate of surface water runoff.

Mitigation Measures: No mitigation measures are required. c.iii. Less than Significant Impact. A project would have a significant impact on surface water hydrology if it would substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river through the addition of impervious surfaces, in a manner which would create or contribute runoff which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff.

As discussed above, the proposed project would not result in a significant increase in site runoff as it would not alter existing drainage patterns or substantially increase the volume or velocity of runoff from impervious surfaces on the site. Runoff from the western portion of the project site would flow west into 24-inch storm drain inlets along Needham Ranch Parkway or debris basins that are planned as part of The Center at Needham Ranch industrial park. Runoff from the eastern portion of the project the majority of runoff from the existing site would be picked up by an existing storm drain inlet along Sierra Highway to the east of the project site and the existing memorial park as under existing conditions. The project would not substantively increase runoff volumes that could affect the existing capacity of the stormwater drainage system or provide substantial additional sources of polluted runoff to the existing drainage system, or otherwise substantially degrade water quality. This impact would be less than significant.

Mitigation Measures: No mitigation measures are required. c.iv. Less than Significant Impact. A project would have a significant impact on surface water hydrology if it would substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river through the addition of impervious surfaces, in a manner that would impede or redirect flood flows. The project is not located in a designated 100-year flood zone.55 Stormwater runoff generated by the proposed building would follow existing drainage patterns and the majority of runoff would flow into existing storm drain inlet to the east, on Sierra Highway. City of Santa Clarita Public Works review will assure project drainage features meet City LID and other stormwater drainage requirements. As such, the project would have a less than significant impact on impeding or redirecting flood flows.

Mitigation Measures: No mitigation measures are required. d. No Impact. A significant impact would potentially occur if the project would risk the release of pollutants from project inundation due to location in a flood hazard, tsunami, or seiche zone.

The project is not located within a 100-year flood zone56 or dam inundation area.57 A seiche, a standing wave created within a large, enclosed body of water due to disturbance, is a concern at water storage facilities because inundation can occur if the wave overflows a containment wall. No major water retaining structures are located immediately upgradient from the project site. Therefore, flooding from seiche is not 55 City of Santa Clarita, City of Santa Clarita General Plan Safety Element, Figure S-4: Surface Water, accessed on February 8, 2022 at: https://www.codepublishing.com/CA/SantaClarita/html/SantaClaritaGP/7%20-%20Safety%20Element.pdf. 56 Ibid. 57 City of Santa Clarita, City of Santa Clarita General Plan Safety Element Figure S-3: Seismic Hazards, accessed on February 8, 2022 at: https://www.codepublishing.com/CA/SantaClarita/html/SantaClaritaGP/7%20-%20Safety%20Element.pdf.

a concern for the project. The project is approximately 22 miles from the ocean and is approximately 1,600 feet above sea level at its lowest point. Therefore, there would be no potential for tsunami inundation on the project site. As such, the project would have no impact pertaining to the risk of release of pollutants due to location in flood hazard, tsunami, or seiche zones.

Mitigation Measures: No mitigation measures are required. e. Less than Significant Impact. A project would have a significant impact if it conflicted with or obstructed implementation of a water quality control plan or sustainable groundwater management plan.

The project site was previously disturbed by grading, is located in a partially developed urban infill site, and does not propose groundwater extraction. The project is required to comply with the Los Angeles Region Municipal Separate Storm Sewer System (MS4) permit (R4-2012-0175), which also serves as a NPDES permit under the Federal Clean Water Act (NPDES No. CAS004001). 58 The project would capture
and convey stormwater consistent with applicable LID regulations. Public Works will review the project Drainage Plans for conformance and provide project conditions to assure compliance. Therefore, the project would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan, and impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. 58 City of Santa Clarita, Municipal Code, Chapter 17.95: Standard Urban Stormwater Mitigation Plan Implementation, accessed on February 8, 2022 at: https://www.codepublishing.com/CA/SantaClarita/html/SantaClarita17/SantaClarita1795.html.

XI. LAND USE AND PLANNING.

Would the project:
a. Physically divide an established community?
b. Cause a significant environmental impact due
to a conflict with any land use plan, policy or
regulation adopted for the purpose of avoiding
or mitigating an environmental effect?
Impact Analysis
a. No Impact. A significant impact may occur if the proposed project would be sufficiently large or otherwise configured in such a way as to create a physical barrier within an established community. The project site is adjacent to the existing memorial park, an industrial park, and a future fire station. The project site is currently zoned as OS59 and designated OS on the land use map, 60 and the City has determined the
use is an allowable use within those designations. As infill, the project would not physically divide an established community. The project would thus have no impact regarding physical division of an established community.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A significant impact may occur if a project causes a significant environmental impact due to inconsistency with the applicable land use plan, policy or regulation, including the zoning designations of the project site. The project site is located within the City and subject to the land use designations and zoning regulations of local land use plans and zoning ordinance.

Regional Plans
Regionally, the project is located within the SCAG planning area, the federally-designated Metropolitan Planning Organization for the region. SCAG is responsible for reviewing regionally significant local plans, projects, and programs for consistency with SCAG's adopted regional plans. As the proposed project is 1) consistent with the General Plan land use designation of OS for the subject property, and 2) impacts would be less than significant or less than significant with mitigation incorporated, and the project would have no regionally-significant impacts, additional analysis of SCAG Plan consistency is not warranted. The project is located within the planning area of the SCAQMD which implements the Air Quality Management Plan (AQMP. As evaluated in Section III., Air Quality, the project is consistent with the AQMP, and no additional analysis is required.

City of Santa Clarita General Plan

ridgeline, but would be subject to the requirements of
a Class IV HDR and RAP from the City.

Policy LU 6.1.3: Ensure that new development in hillside areas is designed to protect the scenic backdrop of foothills and canyons enjoyed by Santa Clarita Valley
communities, through requiring compatible hillside
management techniques that may include but are not
limited to clustering of development; contouring and
landform grading; revegetation with native plants; limited site disturbance; avoidance of tall retaining and build-up walls; use of stepped pads; and other techniques as deemed appropriate.

Consistent: The project would alter topography and
grade within the protected zone of a significant
ridgeline but would be subject to the requirements of
a Class IV HDR and RAP from the City. The only
proposed building is the 3,665 square-foot mausoleum
and most of the project area would be covered in turf
grass, and other landscaping, with some interior paved
roads and no tall retaining walls.

Policy LU 6.5.1: Require use of high quality, durable, and natural-appearing building materials pursuant to
applicable ordinances.

Consistent: The project would expand an existing
memorial park on an adjacent site. The proposed
3,665 square-foot mausoleum building would comply
with all City architectural requirements. The
mausoleum would be consistent with existing off-site
memorial park structures to the east.

Policy LU 6.5.2: Encourage the use of designs and

landscaping, native California plant materials, and
evapotranspiration (smart) irrigation systems.

Consistent: On most of the project site, the project
would place turf grass in the memorial park line areas.

However, landscaping would include native plants
such as coast live oak trees (Quercus agrifolia) and
project trees would be low water use (Water Use
Classification of Landscape Species), as shown on the
preliminary landscape plan.

Policy LU 7.4.2: Require the use of low-flow fixtures in all non-residential development and residential
development with five or more dwelling units, which may include but are not limited to water conserving shower
heads, toilets, waterless urinals and motion-sensor faucets, and encourage use of such fixtures in building retrofits as appropriate.

Consistent: The proposed 3,665 square-foot
mausoleum building would not be inhabited and
would therefore not contain plumbing fixtures. None
of the landscape-related project features would have
plumbing fixtures of the type regulated.

Policy LU 7.5.1: Ensure that all new development
provides adequate space for recycling receptacles and bins on site.

Consistent: There would be adequate space on the
17-acre project site (or on the large, existing memorial park property) for recycling receptacles and bins.

Policy LU 7.5.2: Promote the use of recycled building
materials.

Consistent: The project would comply with the Green
Building Code which sets standards for sustainable
site development, and material conservation.

General Plan Goal or Policy Consistency Analysis
Policy LU 7.6.1: Limit outdoor lighting levels to the
minimum needed for safety and security, and encourage
lower lighting levels when businesses are closed.

Consistent: The expanded memorial park area would
not require substantial outdoor lighting, and there are no adjacent residential land uses.

Policy LU 7.6.2: Preserve habitat connectivity in site
planning where feasible, and discourage the creation of open space islands surrounded by paving.

Consistent: The site would mostly consist of
landscaped grass areas and would not be surrounding
by paving.

Policy LU 7.6.3: Protect wildlife corridors through site design and appropriate land use designations, including mapped corridors and other corridors that may be
identified through biological surveys.

Consistent: As indicated in Section IV, Biological
Resources, the site is not located within a wildlife
corridor and the project would not substantially
interfere with migratory corridors or impede wildlife
movement.

Policy LU 7.6.4: Encourage site designs that protect oak trees, hillsides, and biological resources through creative solutions.

Consistent: As discussed in Section, VII, Geology
and Soils, the project contains hillsides and would
grade within the protected zone of a significant
ridgeline but would be subject to the requirements of
a Class IV HDR and RAP from the City. As discussed
in Section IV, Biological Resources, the project would
have less than significant impacts to oak trees and
biological resources.

Policy LU 7.8.1: Adopt and implement consistent policies for protection of oak woodlands and oak trees throughout the planning area.

Consistent: As indicated in Section IV, Biological
Resources the project would have less than significant
impacts to oak trees. The project site does not contain oak woodlands
Policy LU 7.8.2: Protect all designated Significant
Ecological Areas (SEA’s) from incompatible
development.

Consistent: As indicated in Section IV, Biological
Resources, the project site does not contain SEA.

As shown in Table XI-1, the project would be consistent with the applicable land use policies of the General Plan regarding OS development. The proposed memorial park expansion project would be consistent with the project site’s OS zoning and General Plan Land Use Map designation.

City of Santa Clarita Municipal Code and Zoning
The City General Plan (Land Use Map) designation for the site and adjacent existing memorial park is OS, 62 and the City zoning for the site and adjacent existing memorial park is OS. 63 A zone change would not be
required for the project which proposes an expansion of a memorial park land use and use consistent with OS zoning, according to SCMC Section 17.36.010.
64 Considering the analysis above, the proposed project can be found consistent. Therefore, the project would not conflict with applicable land use plans, policy or regulations of agencies with jurisdiction over the project adopted for the purpose of avoiding or mitigating an environmental effect. The project would result in a less than significant impact.

XII. MINERAL RESOURCES.

Would the project:
a. Would the project result in the loss of
availability of a known mineral resource that
would be of future value to the region and the
residents of the State?
b. Would the project result in the loss of availability of a locally important mineral resource recovery
site delineated on a local general plan, specific
plan, or other land use plan?
Impact Analysis
a-b. No Impact. A significant impact may occur if a project site is located in an area used or available for extraction of a regionally important mineral resource, or if the project would convert an existing or future regionally important mineral extraction use to another use or would affect access to a site used or available for regionally important mineral resource extraction.

The project proposes to expand an existing memorial park, in an urbanized area on a site surrounded on three sides by existing and planned development. The project site is not on an estimated oil and gas field according to the City of Santa Clarita Conservation and Open Space Element.65 According to the California Department of Conservation Mineral Land Classification Map, the project site is located within a Mineral Resource Zone (MRZ)-3, meaning an area containing mineral deposits the significance of which cannot be evaluated from available data, thus significant resources are not known to exist on the project site. 66 The
site is not designated as a locally important mineral resource recovery site as delineated on a local general plan, specific plan, or other land use plan. No mineral resources are known to exist within the project site and additional infill development would not result in the loss of availability of known mineral resources or a locally important mineral resource recovery site. As such, no impact associated with the loss of availability of a known mineral resource would occur.

Mitigation Measures: No mitigation measures are required. 65 City of Santa Clarita, City of Santa Clarita General Plan Conservation and Open Space Element Conservation Element, June 2011. 66 California Department of Conservation, Division of Mines and Geology, Special Report 143, Part V, Plate 5-7, Mineral Land Classification Map: Aggregate Resource Only, 1984.

XIII. NOISE. Would the project result in:
a. Generation of a substantial temporary or
permanent increase in ambient noise levels in
the vicinity of the project in excess of standards
established in the local general plan or noise
ordinance, or applicable standards of other
agencies?
b. Generation of excessive groundborne vibration
or groundborne noise levels?
c. For a project located within the vicinity of a
private airstrip or an airport land use plan or,
where such a plan has not been adopted, within
two miles of a public airport or public use
airport, would the project expose people
residing or working in the project area to
excessive noise levels?
Impact Analysis
This analysis is based upon the project Noise and Vibration Technical Report67 (Appendix J). a. Less than Significant Impact. A project may result in a significant noise impact by generating a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance. The following analysis distinguishes between short-term increases in ambient noise resulting from the use of construction equipment and longterm increases in ambient noise resulting from operation of the proposed memorial park expansion components and vehicular trips generated once the project is in use.

Temporary Noise – Construction
Temporary On-Site Construction Equipment Activity Noise Construction activities are anticipated to include rough grading, with 92,600 cubic yards of cut and fill to be balanced on site. An additional 100,300 cubic yards of dirt will be removed and recompacted onsite. The primary construction equipment noise sources used during construction would be during earthwork activities (use of graders, excavators, dozers), and building construction (use of forklifts, tractors/loaders/backhoes, and a crane). Pile driving would not be required for this project. Of the equipment to be used on site, graders typically generate the highest noise levels, emitting approximately 85 dBA Leq at a distance of 50 feet. During all construction phases, noise-generating activities could occur at the project site between the hours of 7:00 A.M. and 7:00 P.M. Monday through Friday, and 8:00 A.M. and 6:00 P.M. on Saturday in accordance with Section 11.44.080 of the Santa Clarita Municipal Code (SCMC). The projected noise impact from construction activity is shown in Table XIII-1, Construction Noise Impacts at Off-Site Sensitive Receptors and summarized below.

The City has established noise standards for construction activity which requires a building permit and takes place within 300 feet of a residentially zoned property in SCMC Section 11.44.080 Special Noise Sources – Construction and Building. Pursuant to SCMC Section 11.44.080, noise from such construction is prohibited between the hours of 7:00 p.m. and 7:00 a.m. on weekdays, 6:00 p.m. and 8:00 a.m. on Saturday, and/or any time on Sunday or a federal holiday. However, as the nearest residences to the project site are approximately 800 feet away, the project lies further than 300 feet from any residentially zoned property or residential land use and therefore would comply with the SCMC and not expose any residential uses to temporary excessive noises associated with construction activity from the project site. As such, the project would comply with applicable regulations of the SCMC and impacts from construction activities on the nearest sensitive receptors would be less than significant.

Temporary Off-Site Construction Traffic Noise
Construction haul trucks would generate noise off-site during construction activities at the project site. This would include removal of materials from the project site, base materials, and demolished materials. While this vehicle activity would increase ambient noise levels along the haul route, ambient noise levels would not be expected to significantly increase ambient noise levels by 3 dBA or greater at any noise sensitive land use. Studies have shown that a 3 dBA increase in sound level pressure is barely detectable by the human ear. A 3 dBA increase in roadway noise levels requires an approximate doubling of roadway traffic volume, assuming that travel speeds and fleet mix remain constant.68 While this vehicle activity would marginally increase ambient noise levels along the haul route, it would not be expected to significantly increase ambient noise levels by 5 dBA or greater at any noise sensitive land uses. Though the addition of haul trucks would alter the fleet mix of the project haul route, the addition of these trucks to local roadways would be de-minimis. Specifically, construction related traffic would not be doubled on the local roads; thus, traffic volumes and would not produce 5 dBA or more ambient noise increases. As a result, off-site construction noise impacts related to haul trips would be considered less than significant.

Permanent Noise - Operations
Potential long-term noise impacts from the proposed project would result from traffic noise and stationary noise from HVAC and parking.

Permanent Operational Traffic Noise
As discussed above, a 3 dBA increase in roadway noise levels requires an approximate doubling of roadway traffic volume, assuming that travel speeds and fleet mix remain constant. A 3 dBA noise level increase is the minimum noise level increase required for a human to perceive a change in ambient noise. The project is not anticipated to significantly increase the amount of overall traffic going to and from the project site.

Therefore, it is unlikely that there would be an increase in traffic volumes significant enough to cause an audible increase in traffic noise. As such, any noise increase would be imperceptible, and impacts would be less than significant.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 63 June 2022
Permanent Operational Stationary Noise
Regulatory compliance with SCMC Sec. 11.44.070 would ultimately ensure that noises from sources such as HVAC systems not increase ambient noise levels at neighboring occupied properties by more than 5 dBA. Given this regulation, ambient noise levels, and the relatively quiet operation of modern HVAC systems, these on-site noise sources would not be capable of causing the ambient noise levels of nearby uses to increase above the noise limits set forth in SCMC Sec. 11.44.040 and impacts would be less than significant.

Parking noise typically generates noise levels of approximately 60 dBA at 50 feet. The isolated parking areas from parking at the Eternal Valley Memorial Park would ensure that parking noise would be virtually imperceptible to nearby sensitive land uses. Also, the project would not result in a change in employees or visitors, so the number of parked vehicles throughout the memorial park would not increase. Therefore, parking noise would result in a less than significant impact.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A significant impact may occur if the proposed project would expose people to or generate excessive ground-borne vibration or ground-borne noise levels. The Federal Transit Administration (FTA) provides ground-borne vibration impact criteria with respect to building damage during construction activities, measured in PPV, expressed in inches per second (in/sec).

Construction vibration damage criteria are assessed based on structural category (e.g., reinforced-concrete, steel, or timber). FTA guidelines consider 0.2 inch/sec PPV to be the significant impact level for nonengineered timber and masonry buildings. 69 The vibration velocities at nearby sensitive receptors are shown below in Table XIII-2, Vibration Levels at Off-Site Sensitive Uses from Project Construction.

As shown in Table XIII-2 above, the distances from the project site to the nearest sensitive receptors would ensure that any vibration impact would be virtually non-existent. These nearby structures are considered to be a non-engineered timber or masonry buildings and would not experience a PPV groundborne vibration level that exceed the 0.2 in/sec PPV threshold. Therefore, vibration impacts associated with building damage due to project construction activities would result in a less than significant impact.

Mitigation Measures: No mitigation measures are required. c. No Impact. A project located within two miles of a public airport or public use airport may result in a significant impact if a project would the project expose people residing or working in the project area to excessive noise levels. The project site is not in the vicinity of a private airstrip or airport land use plan, but is located near a future helipad at the planned adjacent LACoFD Fire Station. However, the helipad would only be used incidentally, when needed, and the project would not exacerbate the environmental condition of helipad-related noise. The project site is not located within an airport land use plan or within two miles of a public airport or public use airport. Whiteman Airport in the community of Pacoima is 69 Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual. September 2018.

XIV. POPULATION AND HOUSING.

Would the project:
a. Induce substantial unplanned population growth
in an area, either directly (for example, by
proposing new homes and businesses) or
indirectly (for example, through extension of
roads or other infrastructure)?
b. Displace substantial numbers of existing people or
housing, necessitating the construction of
replacement housing elsewhere?
Impact Analysis
a. No Impact. A significant impact may occur if a project would induce substantial unplanned population growth in an area, either directly or indirectly. The project would expand an existing memorial park on undeveloped land. The SCAG 2016-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) forecasts for population and employment growth from 2016 through 2045 for the City of Santa Clarita70 are shown in Table XIV-1, Population and Employment Growth Forecast.

Table XIV-1
Population and Employment Growth Forecast
Year City Population City Employment
2016 218,200 91,200
2045 258,800 105,200
Net Growth 40,600 14,000
Source: SCAG 2020 RTP/SCS, Current Context: Demographics & Growth Forecast Appendix, Table 14, Jurisdictional-Level Growth Forecast, September 3, 2020.

As shown in Table XIV-1, SCAG forecasts City population and employment to increase from 2016 to 2045 by 40,600 people and 14,000 jobs. As the project would expand an existing memorial park, and would not add visitors or employees beyond those currently associated with the memorial park, the project would not introduce population growth. The project would not substantially increase employment. As such, the project would not cause a population increase beyond local and regional projections and would not cause substantial growth that could exceed projected levels for the year of occupancy. As the proposed population would not generate a residential population, cause a substantial increase in employment, or extend existing or new infrastructure that would indirectly induce population growth, the project would have no impact associated with population growth.

Mitigation Measures: No mitigation measures are required. 70 Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual. September 2018.

b. No Impact. A significant impact may occur if a project would result in the displacement of existing housing units or people, necessitating the construction of replacement housing elsewhere. As the project site is undeveloped, the project would not displace persons or residential units or necessitate the construction of replacement housing elsewhere. Therefore, the project would have no impact related to displacement.

Mitigation Measures: No mitigation measures are required.

XV. PUBLIC SERVICES.

Would the project result in substantial adverse
physical impacts associated with the provision of
new or physically altered governmental facilities,
need for new or physically altered governmental
facilities, the construction of which could cause
significant environmental impacts, in order to
maintain acceptable service ratios, response times,
or other performance objectives for any of the public
services:
a. Fire protection?
b. Police protection?
c. Schools?
d. Parks?
e. Other public facilities?
Impact Analysis
a. Less than Significant Impact. A project would normally have a significant impact on fire protection if it requires the addition of a new fire station or the expansion, consolidation, or relocation of an existing facility to maintain service, the construction of which could cause significant environmental impacts. LACoFD Fire Station No. 73, located at 24875 North Railroad Avenue is the nearest existing fire station the project site, 71 approximately 2.4 driving miles to the northwest. In addition, a new fire station is planned adjacent to the project site. The proposed project would not increase population, the number of employees, or visitors. The LACoFD currently serves the project site. Construction of the project would not create substantially more area to cover nor add more population for the LACoFD to serve. Therefore, the project would have a less than significant impact to fire protection services.

The LACoFD participates in the City plan check process, providing review and approval of fire prevention and safety features, including design features such as adequate street widths and access to the building, fire flow pressure, and fire hydrant placement. The project would be served by existing fire hydrants. Given the availability of existing LACoFD stations, the project would not require new or physically expanded fire stations and potential impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A project would normally have a significant impact if it requires new or expanded police station facilities, the construction of which could cause significant environmental impacts, to maintain acceptable service ratios, response times or other performance objectives for police protection.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 68 June 2022
The site is located within the City of Santa Clarita, which contracts police services from the Los Angeles County Sherriff’s Department (LASD). The nearest Santa Clarita Valley Sherriff’s station is located at 26201 Golden Valley Road approximately five driving miles north of the project site.72 The LASD prioritizes emergency calls for police assistance based on the nature of the call. Unlike fire protection services, police units are most often in a mobile state; hence, the distance between a headquarters facility and the location of a particular emergency generally does not determine response times. Instead, the number of police officers on the street is more directly related to the realized response time.

Construction
Construction sites can attract vandalism. Due to the temporary nature of project construction and the visible location within the existing Eternal Valley Memorial Park and Mortuary, such potential impacts would not require the construction or expansion of police facilities to serve the site or maintain service response times.

Also, given the same ownership and proximity to the remainder of the memorial park which has onsite staff, vandalism is not considered likely. Further, as with all of the City, the site would be monitored during routine LASD patrols. Impacts would be less than significant.

Operation
The project would expand an existing memorial park. As the project would not introduce new residents, the project would not result in a substantial increase in the LASD service area population such that new or physically altered police facilities would be needed to maintain performance objectives. Therefore, potential operational impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. c. No Impact. A significant impact may occur if a project includes substantial employment or population growth, which could generate a demand for school facilities. As the project would not generate residents, the project would not generate a demand for school facilities that would exceed the capacity of Newhall School District schools, and therefore would not result in a need for new or improved facilities that would create in a physical impact on the environment. The project would have no impact pertaining to schools.

Mitigation Measures: No mitigation measures are required. d. No Impact. A significant impact would occur if the recreation and park services available could not accommodate a project-related population increase and the proposed project resulted in the construction of new recreation and park facilities that create significant environmental impacts. As the project would not introduce a new residential population, the project would not result in an increase in park usage, and no new or physically expanded park facilities would be needed. Therefore, the project would have no impact pertaining to park and recreation facilities.

Mitigation Measures: No mitigation measures are required. e. No Impact. A significant impact could occur if the project result in substantial adverse physical impacts associated with other physically altered governmental facilities, need for new or physically altered governmental facilities that would create significant environmental impacts. As the project consists of an expansion of an existing memorial park and would not increase visitors or staff, the project would not 72 Tracey Jue, Director, Facilities Planning Bureau, Los Angeles County Sheriff’s Department, Notice of Intent to Adopt a Mitigated Negative Declaration: Eternal Valley Memorial Park Expansion Project Review Comments (Master Case 20-231), June 2022.

XVI. RECREATION.
a. Would the project increase the use of existing
neighborhood and regional parks or other
recreational facilities such that substantial
physical deterioration of the facility would occur
or be accelerated?
b. Does the project include recreational facilities or
require the construction or expansion of
recreational facilities, which might have an
adverse physical effect on the environment?
Impact Analysis
a. No Impact. A significant impact may occur if a project includes substantial employment or population growth, which would increase the use of existing neighborhood and regional parks or other recreational facilities, such that substantial physical deterioration of the facility would occur or be accelerated. The City provides numerous recreational facilities within the area for a variety of recreation opportunities. The proposed project would not add any residential units and expand an existing memorial park. No change in population would occur. Therefore, the project would not result in a substantial increase in park usage such that substantial physical deterioration of the facility would occur or be accelerated.

Therefore, the project would have no impact pertaining to park and recreation facilities.

Mitigation Measures: No mitigation measures are required. b. No Impact. A significant impact may occur if a project includes the construction or expansion of park facilities and such construction would have a significant adverse effect on the environment. As discussed in Section XVI.a., the project would not introduce a new residential population, the project would not result in an increase in park usage or recreational facilities usage. The project would not require the construction or physical expansion of existing recreational facilities and therefore, the project would have no impact.

Mitigation Measures: No mitigation measures are required.

XVII. TRANSPORTATION. Would the project:
a. Conflict with a program, plan, ordinance or
policy addressing the circulation system,
including transit, roadway, bicycle and
pedestrian facilities?
b. Would the project conflict or be inconsistent
with CEQA Guidelines section 15064.3,
subdivision (b)?
c. Substantially increase hazards to a geometric
design feature (e.g., sharp curves or dangerous
intersections) or incompatible uses (e.g., farm
equipment)?
d. Result in inadequate emergency access?
Impact Analysis
The City Local Guidelines and Procedures for Implementation of the Provisions of CEQA contain thresholds related to Level of Service (LOS), however subsequent legislation has removed LOS and similar measurements of vehicular roadway capacity and traffic congestion as the basis for determining significant traffic impacts under CEQA, as discussed below, under threshold XVII.b.

The following incorporates information from Traffic Memorandum for the project, prepared by Clark and Green Associates, included as Appendix K, Traffic Memorandum. 73 As discussed in the memo, memorial
parks or cemeteries are very low traffic generators in general. The expansion of a memorial park does not increase traffic, but visitations shift from older areas to newer areas over time. The project related trips would be less than the 250 daily project trips, the City screening threshold for required analysis of vehicle miles traveled (VMT) impacts, and therefore a VMT study would not be required. a. No Impact. A significant impact may occur if the project would conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities. The project construction would be temporary and would not affect overall pedestrian and roadway area access. Project operations would not increase the number of employees or visitors and would therefore not generate substantial additional vehicle trips. No conflicts would occur with regard to a program, plan, ordinance, or policy addressing the circulation system; and no project impact would occur.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. A significant impact may occur if the project would conflict or be inconsistent with CEQA Section 15064.3 subdivision (b). Senate Bill 743 (SB 743) was enacted in September 2013 changing the way transportation impact analysis is conducted under CEQA. These changes include the elimination of auto delay, LOS, and similar measurements of vehicular roadway capacity and traffic congestion as the basis for determining significant traffic impacts under CEQA. In accordance with the Governor’s Office of Planning and Research revisions to the CEQA statute and Guidelines, a lead agency must comply by July 1, 2020, but may elect to be governed by the VMT guidelines immediately. 73 Clark & Green Associates, Eternal Valley Memorial Park Traffic Review, August 23, 2021.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 72 June 2022
While the use of VMT to determine impacts would replace the analysis of LOS for CEQA purposes (including the determination of significance), agencies may continue to use LOS for other purposes.

Construction Vehicle Trips
The phases of the construction process –grading, trenching, vertical construction, paving, and architectural coating – are expected to last approximately a year and a quarter. During this process, work crew vehicles, and delivery trucks would enter and exit the site from public roadways. The project site and adjacent areas within the memorial park have sufficient space for temporary construction crew parking and equipment staging to take place during all phases of construction, thereby minimizing the interference of construction vehicles with existing vehicle circulation. The project would comply with applicable construction traffic control requirements, thereby reducing temporary construction-related traffic impacts to less than significant.

Operational Vehicle Trips
The project would not increase the number of employees or visitors and therefore would not generate substantial additional trips or VMT. As such, operational traffic impacts would be less than significant with respect to VMT.

Mitigation Measures: No mitigation measures are required. c. No Impact. A significant impact may occur if the project would substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment).

The project would not modify access to the memorial park and would not increase hazards or introduce incompatible uses. The project would not affect design of any public roadways or introduce incompatible uses. The project’s private internal loop road would not have hazardous design features. In addition, the project would not create or alter any driveways to the offsite street network.

Mitigation Measures: No mitigation measures are required. d. No Impact. A significant impact may occur if the project would result in inadequate emergency access Sierra Highway, which is a public roadway that has two lanes in each direction and a median, provides access to the existing memorial park and the project site. The project would not increase the number of employees or visitors and would not generate substantial additional vehicle trips. The project would not inhibit any emergency access routes as it would be fully contained on the existing parcel. The project would construct an internal loop road for the project site within the overall memorial park, would not require or build or alter any new public roads, access roads, or parking lots. The project design would be subject to requirements and approval of the City. Therefore, the project would have no impact with regard to emergency access.

Mitigation Measures: No mitigation measures are required.

XVIII. TRIBAL CULTURAL RESOURCES.

Would the project cause a substantial adverse change
in the significance of a tribal cultural resource,
defined in Public Resources Code section 21074 as
either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope
of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that
is:
a. Listed or eligible for listing in the California
Register of Historical Resources, or in a local
register of historical resources as defined in
Public Resources Code section 5020.1(k)?
b. A resource determined by the lead agency, in
its discretion and supported by substantial
evidence, to be significant pursuant to criteria
set forth in subdivision “c” of Public Resources
Code Section 5024.1. In applying the criteria
set forth in subdivision “c” of Public Resources
Code Section 5024.1, the lead agency shall
consider the significance of the resource to a
California Native American tribe.

Impact Analysis
The following analysis is based on the Phase I Archaeological Resources Assessment of the project site prepared by ArcheoPaleo Resource Management, Inc. that included a record search from the California NAHC (Appendix E). The City has received a request from the Fernandeño Tataviam Band of Mission Indians for Tribal Consultation under AB-52.
a. No Impact. A significant impact would occur if a project would cause a substantial adverse change in the significance of a tribal cultural resource as defined in PRC Section 21074 listed, or eligible for listing, in the California Register of Historical Resources, or in a local register of historical resources. As discussed in Section V.a, in Cultural Resources, the site is improved and does not contain historical resources. The Phase I Archaeological Resources Assessment involved a SCCIC record search of the subject property plus a 0.25-mile radius surrounding the subject property (combined, the “study area”). The results of the SCCIC record search found a previously identified historic structure (P-19-186861) and two cultural resource reports (LA-02317 and LA-03829) within the study area. The historic structure is outside the project site and would not be affected by the project, did not find any cultural resources within the project site. No additional cultural resource reports dealt with the development footprint. Therefore, the project would not cause a substantial adverse change in the significance of a tribal cultural resource, defined in PRC section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American

tribe, and that listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in the PRC, and no impact would occur.

A total of four (4) responses were received from the tribes, individuals, and organizations contacted by ArchaeoPaleo Resource Management, Inc. from the Native American Contact List that was provided by the NAHC, due to the proximate nature of two Native American villages nearby. The City has received a request for tribal consultation from the Fernandeño Tataviam Band of Mission Indians.

Mitigation Measures: No mitigation measures are required. b. Potentially Significant Unless Mitigation Incorporated. A significant impact would occur if a project would cause a substantial adverse change in the significance of a tribal cultural resource as defined in PRC Section 21074 determined by the lead agency, in its discretion and supported by substantial evidence, to be significant, with the agency taking into consideration the significance of the resource to a California Native American tribe.

As described above in Section V., Cultural Resources, a less than significant impact would occur to a tribal cultural resource defined in the PRC has been proposed or would occur. Section V. includes mitigation measures for archaeological monitoring, which includes Native American monitoring, and the inadvertent discovery of human remains, which would include Native American human remains. With mitigation, project impacts would be less than significant.

Mitigation Measures: MM CUL-1, which includes Native American monitoring MM CUL-2, which addresses the inadvertent discovery of human remains, shall apply (see Section V). No additional mitigation measures are required.

XIX. UTILITIES AND SERVICE
SYSTEMS. Would the project:
a. Require or result in the relocation or
construction of new or expanded water,
wastewater treatment, or storm water drainage,
electric power, natural gas, or
telecommunications facilities, the construction
or relocation of which could cause significant
environmental effects?
b. Have sufficient water supplies available to serve
the project and reasonably foreseeable future
development during normal, dry, and multiple
dry years?
c. Result in a determination by the wastewater
treatment provider, which serves or may serve
the project, that it has adequate capacity to serve
the project’s projected demand in addition to the
provider’s existing commitments?
d. Generate solid waste in excess of State or local
standards, or in excess of the capacity of local
infrastructure, or otherwise impair the
attainment of solid waste reduction goals?
e. Comply with federal, State, and local
management and reduction statutes and
regulations related to solid waste?
Impact Analysis
a. Less than Significant Impact. A significant impact may occur if a project would require or result in the relocation or construction of new or expanded water, wastewater treatment, stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction of which could cause significant environmental effects. The project would generate water, wastewater, and stormwater typical of turf landscaped areas in compliance with applicable federal, State, and local laws, statutes, and ordinances.

As infill development on a site currently served with existing public utilities infrastructure, the project would not result in the relocation or substantial expansion of that infrastructure. See Section XIX.b. for an analysis of water supply and XIX.c. for an analysis of wastewater capacity. The project would not require addition of offsite water lines (only minor onsite extensions from the existing memorial park for landscape irrigation) or any additional wastewater infrastructure. The project would generate a marginal increase in demand for electric power facilities and no increase in natural gas or telecommunications facilities, and as such the project would have a less than significant impact.

Mitigation Measures: No mitigation measures are required.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 76 June 2022
b. Less than Significant Impact. A significant impact would occur if the project did not have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry, and multiple dry years.

The Newhall Water Division of the Santa Clarita Valley Water Agency (SCV Water) currently serves as the potable water purveyor to the project vicinity and would provide potable water to the project. SCV Water was created in 2018 through a merger of the Castaic Lake Water Agency, Newhall County Water Districts, and Valencia Water Company. According to its 2020 Urban Water Management Plan (UWMP), SCV Water has sufficient water supplies available for normal year water demands, as well as for dry and multiple dry years through the Year 2050 with existing supply, conjunctive use (coordinated use of surface water and groundwater), water conservation, water transfers, recycled water, and water banking. 74 Water
supplies for 2050 for multiple dry years are projected by the UWMP to be 128,715 acre-feet per year (AFY) and demand with passive and active conservation is estimated at 102,870 AFY.

The project would construct and operate approximately 15 acres of memorial park space. The project would require irrigation, which would use 19,091,257 gallons per year or 70.4 AFY, according to the project Irrigation Water Use Plan.
75 This amount of water use would equal 0.3% of projected surplus supply in 2050, assuming multiple dry years. There would not be an increase in inhabited building square footage and there would be no increase in the number of employees or net number of visitors and therefore no increase in water demand from plumbing fixtures.

The proposed project would not construct inhabited buildings and would therefore not install water fixtures such as toilets, sinks, and showers. Based on the availability of water supplies indicated in the UWMP, SCV Water would have sufficient water supply to serve the project and reasonably foreseeable future development accounted for in the UWMP. The project would have a less than significant impact.

Mitigation Measures: No mitigation measures are required. c. Less than Significant Impact. A significant impact would occur if a project would result in a determination by the wastewater treatment provider, which serves or may serve the project, that it does not have adequate capacity to serve a project’s projected demand in addition to the provider’s existing commitments.

The Los Angeles County Sanitation District currently serves the wastewater needs of project site and would serve the project. Wastewater generated from the project site would be conveyed to the Valencia Water Reclamation Plant.
76 Currently, the Valencia Water Reclamation Plant treats an average of 15.7 million gallons per day (mgd) of wastewater with the capacity to treat 21.6 mgd, and therefore has excess capacity of approximately 5.9 mgd.77
Existing sewer infrastructure would serve the project site. As the project would not increase inhabited building square footage, there would be no increase in the number of plumbing fixtures. There would also be no increase in employees or visitors. There would therefore be no substantial increase in water demand.

Impacts would be less than significant.

Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 77 June 2022
Mitigation Measures: No mitigation measures are required. d. Less than Significant Impact. A significant impact may occur if a project were to increase solid waste generation to such a degree that the existing and projected landfill capacity would be insufficient to accommodate the additional solid waste. Solid waste generated within the City is recycled, reused, and transformed at waste-to-energy facilities or disposed of at landfills. The Chiquita Canyon Landfill would serve the proposed project site and is managed by Waste Connections. The landfill has a remaining capacity of 56,864,241 tons or 53,645,510 cubic yards as of December 31, 2019 and is scheduled to operate until July 25, 2047, unless its capacity is reached earlier. The Chiquita Canyon Landfill accepts municipal solid waste, green waste, construction and demolition debris, clean dirt, and e-waste (for recycling). 78 Construction
The project would not demolish any buildings or paved surfaces as there are none on the site, and therefore would not generate demolition waste.

The project would require construction waste diversion of at least 65 percent, in accordance with the California Green Building Standards Code (Section 5.408). Total construction waste disposal from the project, 5.14 tons, would be disposed over 302 days total79 or approximately 0.02 tons per day (tpd) of waste, which represents less than one percent (0.0003 percent) of the 5,525 tpd of permitted capacity for waste daily disposal capacity at Chiquita Canyon Landfill,80 and the impact would be short-term.

Construction waste generation would be short-term and would not exceed the daily permitted capacity of the Chiquita Canyon Landfill resulting in a less than significant impact.

Operations
Future employees of the proposed memorial park expansion would generate solid waste typical of memorial park uses. Collection of solid waste would be provided by Burrtec Waste Industries, Inc., which is the existing provider for the memorial park. As the project would not increase inhabited building square footage, there would be no increase in the number of employees or visitors and no increase in landfill capacity demand. Therefore, operational solid waste impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. e. Less than Significant Impact. A significant impact may occur if a project would generate solid waste not disposed of in accordance with applicable regulations. The project would generate solid waste typical of memorial park uses and would comply with applicable federal, State, and local laws, statutes, and ordinances regarding the proper disposal of solid waste. Appropriate disposal of potentially hazardous materials from construction is required, as discussed in Section IX, Hazards and Hazardous Materials, and impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. 78 Waste Connections, Chiquita Canyon, Using Chiquita, Accessed on January 24, 2022 at: https://chiquitacanyon.com/usingchiquita/. 79 Roughly: 261 days building construction, 10 days paving, 31 days architectural coating. 80 Los Angeles County Public Works, Countywide Integrated Waste Management Plan: 2019 Annual Report, September 2020.

XX. WILDFIRE.

If located in or near State responsibility areas or land classified as very high fire hazard severity zones,
would the project:
a. Substantially impair an adopted emergency
response plan or emergency evacuation plan?
b. Due to slope, prevailing winds, and other factor,
exacerbate wildfire risks, and thereby expose
project occupants to pollutant concentrations
from a wildfire or the uncontrolled spread of a
wildfire?
c. Require the installation of associated
infrastructure (such as roads, fuel breaks,
emergency water sources, power lines or other
utilities) that may exacerbate fire risk or that
may result in temporary or ongoing impacts to
the environment?
d. Expose people or structures to significant risks,
including downslope or downstream flooding or
landslides, as a result of runoff, post-fire slope
instability, or drainage changes?
Impact Analysis
Wildfires are of particular concern in areas designated as a VHFHSZ. As shown on the California Department of Forestry and Fire Protection’s map, the project site is located within land classified as a VHFHSZ.81
a. Less than Significant Impact. The project may have a significant impact if it would substantially impair an adopted emergency response plan or emergency evacuation plan. The project would expand an existing memorial park. While the project is within land classified as a VHFHSZ, the site project would be surrounded on three sides by existing and planned development: the existing portion of the memorial park to the east, the Needham Ranch industrial park to the west, and the future Los Angeles County Fire station to the south. The project site and surrounding vicinity would be served by existing vehicular ingress and egress routes to State Route 14 (the Antelope Valley Freeway) and Interstate 5 (the Golden State Freeway).

The Safety Element of the City General Plan designates these roadways as evacuation routes.82 Similar to the existing memorial park, the proposed expansion of the memorial park would not permanently alter vehicular circulation routes or impair public access upon public rights-of-way, including access to and from the evacuation routes. The memorial park has sufficient space for temporary construction crew parking and equipment staging to take place in and around the project site within the memorial park during all phases of construction, thereby minimizing the interference of construction vehicles with existing vehicle 81 California Department of Forestry and Fire Protection, Very High Fire Hazard Severity Zones in LRA as Recommended by CAL FIRE: Santa Clarita, September 2011.

circulation. Therefore, neither project construction nor operations would physically interfere with an adopted emergency response plan or emergency evacuation plan, impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. b. Less than Significant Impact. The project may have a significant impact if, due to slope, prevailing winds, and other factors, the project would exacerbate wildfire risks, and thereby expose project occupants to pollutant concentrations from a wildfire or uncontrolled spread of a wildfire. The project site has an average slope of greater than fifteen percent, is downslope of naturally vegetated hillsides, and is located in a VHFHSZ. The site is within the Wildland Urban Interface.

The project is subject to a HDR (Class IV) Permit (HDR), which is required because the project site has an average slope of greater than fifteen percent and because the project would cut and fill more than 1,500 cubic yards of earth83 on a natural slope greater than ten percent average. The proposed expansion area would be irrigated, once developed, and all landscaping would be required to comply. The proposed mausoleum building would meet all the latest fire code requirements. In addition to meeting fire code requirements, existing LACoFD fire stations in the vicinity would serve the proposed project. LACoFD Fire Station No. 73, located at 24875 North Railroad Avenue is the nearest existing fire station the project site,
84 approximately 2.4 driving miles to the northwest. In addition, a new fire station is planned adjacent to the project site. Although the project site is within a VHFHSZ, it would be compliant with the Fire Code and is proximate to multiple LACoFD Stations and the memorial park and nearby urban uses have existing water and fire hydrant infrastructure, impacts would be less than significant.

Mitigation Measures: No mitigation measures are required. c. No Impact. A project may have a significant impact if it would require the installation of associated infrastructure that may exacerbate fire risk or may result in temporary or ongoing impacts to the environment. The project is essentially infill development (given development on three sides) and would be surrounded on three sides by existing and planned development and would be an expansion of an existing land use served by existing roads, emergency water sources, power lines, and utilities. Therefore, the project would not result in the installation of associated infrastructure that may exacerbate fire risk or result in temporary or ongoing impacts to the environment, and the project would have no impact.

Mitigation Measures: No mitigation measures are required. d. Less than Significant Impact. A project may have a significant impact if it would expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes.

The project site has an average cross-slope of greater than fifteen percent and is immediately downslope from naturally vegetated hillsides, but is not located in a designated flood risk zone.85 As indicated in Section X, Hydrology and Water Quality, stormwater runoff generated by the proposed project would adhere to LID requirements which reduce drainage across the site and would follow existing drainage patterns, with the majority of runoff flowing into the existing storm drain inlet on Sierra Highway. The urban project location and compliance with applicable regulatory requirements would not expose people or 83 As noted in the Project Description, project grading would cut and fill a total of 192,900 cubic yards of earth, including mass excavation and fill, over- excavation, and shrinkage, which would be balanced on site. 84 Los Angeles County Fire Department, Search Results.

XXI. MANDATORY FINDINGS OF
SIGNIFICANCE.
a. Does the project have the potential to
substantially degrade the quality of the
environment, substantially reduce the habitat of
fish or wildlife species, cause a fish or wildlife
population to drop below self-sustaining levels,
threaten to eliminate a plant or animal
community, substantially reduce the number or
restrict the range of a rare or endangered plant or
animal or eliminate important examples of the
major periods of California history or
prehistory?
b. Does the project have impacts that are
individually limited, but cumulatively
considerable? (“Cumulatively considerable”
means that the incremental effects of an
individual project are considerable when viewed
in connection with the effects of past projects,
the effects of other current projects, and the
effects of probable future projects).
c. Does the project have environmental effects that
cause substantial adverse effects on human
beings, either directly or indirectly?
Impact Analysis
a. Potentially Significant Unless Mitigation Incorporated. A significant impact could occur if a project would significantly degrade the quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory.

The project site is in an urbanized area surrounded by surrounded on three sides by existing and planned development, including streets and utilities and public service infrastructure. The project is an expansion of the existing cemetery land use and the site has existing or planned development on three sides. As discussed in Section IV., Biological Resources, the project’s impacts to these resources would be reduced to than significant with mitigation (MM BIO-1 through MM BIO-4). Similarly, as discussed in Section V., Cultural Resources, project impacts to these resources would be reduced to less than significant with mitigation (MM CUL-1 and MM CUL-2). Therefore, the project would not significantly degrade the quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory and impacts would be less than significant.

4.0 INITIAL STUDY/NEGATIVE DECLARATION
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 82 June 2022
Mitigation Measures: MM BIO-1 through MM BIO-4, MM CUL-1, and MM CUL-2 are required, as discussed in Section IV and Section V.
b. Less than Significant Impact. A significant impact may occur if the impacts of the proposed project, in conjunction with the impacts of related projects, would result in impacts that are less than significant when viewed separately but significant when viewed together.

As discussed throughout this document, with mitigation none of the project’s impacts would be considered significant. However, none of the issues evaluated are at a currently known cumulative impact level high enough where even a small contribution from a project could result in a cumulatively significant impact.

Therefore, the proposed project’s contribution would not be cumulatively considerable and would not significantly add or create a significant cumulative impact.

Mitigation Measures: No mitigation measures are required. c. Less than Significant Impact. A significant impact may occur if the proposed project has the potential to result in significant impacts to humans either directly or indirectly. As all impacts to humans would be less than significant with regulatory compliance, no substantial adverse impacts on human beings, either directly or indirectly, would occur and impacts would be less than significant.

Mitigation Measures: No mitigation measures are required.

7.0 RESPONSE TO COMMENTS
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 88 June 2022

7.0 RESPONSE TO COMMENTS
Following distribution of the draft Notice of Intent and Initial Study/Mitigated Negative Declaration (IS/MND) for the project, two comment letters were received on the IS/MND. The comment letters are shown on the following pages and the responses are provided below.

COMMENT LETTER NO. 1 ± Tracey Jue, Director, Facilities Planning Bureau, Los Angeles County 6KHULII¶V'HSDUWPHQW
Response to Letter No. 1
The comment letter states that “visitors and daytime population will increase contrary to what is stated in the NOI/MND.” However, as discussed in Chapter 4, Section XVII, Transportation of the IS/MND, expansions of memorial parks do not increase visitors, because visitation of older areas of a memorial park decreases over time, resulting in a net balance of visitors, as visitation shifts from older to newer areas.

Nonetheless, the comment goes on to state that the project “may not substantially” affect service demand or response times and expresses agreement with the corresponding assessment in the IS/MND. The comment letter states that the location of the nearest police station should be updated to 26201 Golden Valley Road, which is five (5) driving miles from the project, as this station is now operational. Chapter 4, Section XV, Public Services of the Final MND will be updated accordingly.

Recommendations that the project applicant and its contractors coordinate with the Sheriff’s Department regarding road safety during construction of the project are included in the comment letter. Coordination with state and local agencies for haul routes and construction and demolition waste disposal is also recommended. The comment further recommends security measures such as fencing and security lighting where appropriate during construction. The project applicant and its contractors would coordinate with the appropriate agencies during construction of the project. Construction fencing would be in place during construction of the project and the construction contractor would implement appropriate nighttime security measures.

The letter states the site should have a secondary emergency vehicle access, with a Knox box. A 36-foot minimum width for the proposed loop road is recommended by the letter to allow parking on both sides without obstructing vehicle flow. The project as proposed already includes a secondary emergency access from Needham Ranch Parkway that would be used by emergency vehicles and would have a Knox box.

The proposed minimum loop road width is approximately 28 feet, which is similar to the existing memorial park roads. The City finds this width is sufficient, as the memorial park does not have a history of emergency issues with its existing facility, and accordingly these issues would not be anticipated in the expansion area. In addition, the proposed project site plan will be reviewed by the Los Angeles County Fire Department, which will require sufficient emergency access for approval. Based on the above analysis, no changes to the IS/MND are required.

Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 92 June 2022
COMMENT LETTER NO. 2 ± Ronald M. Durbin, Chief, Forestry Division, Prevention Services Bureau, Los Angeles County Fire Department
Response to Letter No. 2
The letter states that the NOI/MND was reviewed by the Planning Division, Land Development Unit, Forestry Division, and Health Hazardous Materials Division of the Los Angeles County Fire Department.

The Planning Division stated that they have no comments. The Land Development Unit stated that they have no additional comments, and their previous comments were addressed in the Conditions of Approval for MC 20-231. They also state that the project must “comply with all applicable code and ordinance requirements for construction, access, water mains, fire flows and fire hydrants.” The letter goes on to state that construction fire and safety requirements will be addressed by the Fire Department during building plan check review, at which time they may have additional requirements. Based on the lack of mention of further environmental concerns, it is assumed the plan check requirements would be minor design requirements that do not rise to the level of comments or revisions to the IS/MND. Also discussed is the requirement that the project submit a Fuel Modification Plan to the Fuel Modification Unit before a building permit can be issued. The project will submit a Fuel Modification Plan before the proposed mausoleum can receive a building permit. No changes to the IS/MND are required.

The Forestry Division notes that the subject property is within a Fire Hazard Severity Zone, and thus is subject to applicable code and ordinance requirements for fuel modification. As discussed previously within this response, the project will submit a Fuel Modification Plan before the proposed mausoleum can receive a building permit. The Forestry Division states that potential impacts in the areas of erosion control, watershed management, rare and endangered species, brush clearance, vegetation management, fuel modification for Fire Hazard Severity Zones, archeological and cultural resources, and the County Oak Tree Ordinance should be addressed. The IS/MND evaluated these issues and found the project would have less than significant impacts in the areas of erosion control and watershed management, as discussed in Chapter 4, Section VII, Geology and Soils and Chapter 4, Section X, Hydrology and Water Quality. The project would have less than significant impacts with mitigation in the area of rare and endangered species, as discussed in Chapter 4, Section IV, Biology, and in the area of archaeological and cultural resources, as discussed in Chapter 4, Section V, Cultural Resources and Chapter 4, Section XVIII, Tribal Cultural Resources. Brush clearance, vegetation management, and fuel modification will be addressed in the Fuel Modification Plan that will be required before the proposed mausoleum can receive a building permit. The County Oak Tree Ordinance is not applicable, as the project is within the City of Santa Clarita. As discussed in Chapter 4, Section IV, Biology, no oak trees would be removed by the project, which would comply with the City’s Oak Tree Preservation Ordinance and install protective fencing during construction. As discussed in Chapter 3, Project Description, the project would require an Oak Tree Permit (Class II) as an entitlement.

Project impacts to oak trees would be less than significant. No changes to the IS/MND are required.

The Health Hazardous Materials Division stated that they have no comments or requirements for the project.

8.0 CORRECTIONS AND ADDITIONS
Eternal Valley Expansion Project Initial Study/Mitigated Negative Declaration City of Santa Clarita 96 June 2022

8.0 CORRECTIONS AND ADDITIONS
Three corrections/additions were made to the draft IS/MND to complete this final IS/MND. The changes are as follows:

In Section V, Cultural Resource, checklist item b., on pages 30 and 31, the text of MM CUL-1 was revised, after tribal consultation:

Archaeological resources monitoring shall be conducted by an archaeological resource monitor, during project related earth-disturbing activities, per the California Office of Historic Preservation (OHP) standards, under the supervision of a qualified Lead Archaeologist. Monitoring will entail visual inspection of projectrelated earth-disturbing activities (,e.g., grading, excavation, trenching, shoring, etc.)
The project proponent shall retain a professional Native American Monitor procured by the Fernandeño Tataviam Band of Mission Indians or consulting Tribes under AB52 to observe all ground-disturbing activities An approved Native American monitor(s), with documented ancestral ties to the area consistent with the standards of the NAHC shall be present for all ground disturbing activities that involve excavation of previously undisturbed soil. Monitoring will entail visual inspection project related earth-disturbing activities… The Lead Agency and project proponent shall, in good faith, consult with the Fernandeño Tataviam Band of Mission Indians on the disposition and treatment of Tribal Cultural Resources encountered during Project implementation.

In Section VII, Geology and Soils, checklist item a. iv, on page 38, typographical errors were corrected to remove text for clarity, not in response to a comment:

With the incorporation of the recommendations of the Geotechnical & Geological Investigation into the project employees and visitors would not increase as a result of the project as a part of the regulatory review process and a project feature. Therefore, impacts related to landslides would be less than significant and mitigation measures would not be required.

In Section XV, Public Services, checklist item b., on page 69, the location of the nearest police station was updated in response to comments from the Los Angeles County Sheriff’s Department:

The nearest Santa Clarita Valley Sherriff’s station is located at 26201 Golden Valley Road approximately 9.8 five driving miles north of the project site.72 In addition, on Section XV, Public Services, checklist item b., on page 69, footnote “72” was added to cite the letter from the Los Angeles County Sheriff’s Department as the source for the location of the nearest police station. The same reference was added to page 87 within the list of references:
72 Tracey Jue, Director, Facilities Planning Bureau, Los Angeles County Sheriff’s Department, Notice of Intent to Adopt a Mitigated Negative Declaration: Eternal Valley Memorial Park Expansion Project Review Comments (Master Case 20-231), June 2022.

Additional minor typographical errors were corrected in other parts of the document, not in response to a comment.

1.0 INTRODUCTION
This Air Quality and Greenhouse Gas Technical Study describes air quality and greenhouse gas (GHG) emissions associated with the proposed development at the Eternal Valley Memorial Park and Mortuary (Project) in the City of Santa Clarita (City) and evaluates potential impacts. This report has been prepared by Impact Sciences, Inc., to support the environmental documentation being prepared pursuant to the California Environmental Quality Act (CEQA) for the City of Santa Clarita. This analysis considers both the temporary air quality and GHG impacts from Project construction and long-term impacts associated with operation of the proposed Project.

1.1 PROJECT LOCATION
The Project site is located at 23287 Sierra Highway in the City. The Project is located within Newhall neighborhood area in the southern portion of the City. The site is on the western portion of the Eternal Valley Memorial Park and Mortuary, bounded by Needham Ranch Parkway on the west, open space brush areas to the north, previously developed areas of the Eternal Valley Memorial Park and Mortuary to the east, and industrial warehouses to the south.

The Project site is approximately 17 acres, zoned OS – Open Space, and is currently undeveloped, see Figure 1, Project Site.

1.2 PROJECT DESCRIPTION
The proposed Project consists of rough grading, future lawn burials, and the construction of a community mausoleum. The Project includes approximately 17 acres of grading across the Project site. The Project would be graded with a volume totaling 92,600 cubic yards of cut and fill to be balanced on site. An additional 100,300 cubic yards of dirt will be removed and recompacted onsite in accordance with the Project’s soils report recommendations for remedial grading. No soil import or export is anticipated at this time.

The 3,665 square foot mausoleum will be set into the hillside and would have a capacity of 780 caskets. A central room would include housing niches for the inurnment of cremated remains. The structure will lie below the ridgeline elevation.

The Project would also include traditional lawn burial gardens consistent with the overall cemetery appearance and a private cemetery loop road for access by cemetery visitors and will include an Americans with Disabilities Act (ADA) parking stall. Shade trees would also be placed in the same general density

2.0 AIR QUALITY

2.1 AIR QUALITY SETTING
South Coast Air Basin
South Coast Air Basin Characteristics1
The California Air Resources Board (CARB) divides the state into air basins that share similar meteorological and topographical features. The City is located within the South Coast Air Basin (SCAB), which incorporates approximately 12,000 square miles consisting of Orange County and the non-desert portions of Los Angeles, Riverside, and San Bernardino Counties, in addition to the San Gorgonio Pass area in Riverside County. SCAB is a coastal plain with connecting broad valleys and low hills, bounded by the Pacific Ocean to the southwest and high mountains around the rest of its perimeters. The South Coast Air Quality Management District (SCAQMD) divides the Basin into source receptor areas (SRAs) in which monitoring stations operate to monitor the various concentrations of air pollutants in the region. The Project site is located within SRA 13, which covers the Santa Clarita Valley area.

Climate and Meteorology
The general region lies in the semi-permanent high-pressure zone of the eastern Pacific, resulting in a mild climate tempered by cool sea breezes with light average wind speeds. It is considered semi-arid and is characterized by warm summers, mild winters, infrequent seasonal rainfall, moderate daytime onshore breezes, and moderate humidity. This usually mild climatological pattern is interrupted occasionally by periods of extremely hot weather, winter storms, or Santa Ana winds. The annual average temperature varies little throughout the SCAB region, ranging from the low 60s to the high 80s, measures in degrees Fahrenheit (F°). With a more pronounced oceanic influence, coastal areas show less variability in annual minimum and maximum temperatures than inland areas.

In contrast to a very steady pattern of temperature, rainfall is seasonally and annually highly variable.

Almost all annual rains fall between November and April. Summer rainfall is normally restricted to widely scattered thundershowers near the coast, with slightly heavier shower activity in the east and over the mountains.
1 The discussion of meteorological and topographical conditions of the SCAB is based on information provided in the Final 2016 Air Quality Management Plan.

2.0 Air Quality
Impact Sciences, Inc. 5 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
Humidity
Although the SCAB has a semiarid climate, the air near the earth’s surface is typically moist because of the presence of a shallow marine layer. Except for infrequent periods when dry, continental air is brought into the SCAB by offshore winds, the “ocean effect” is dominant. Periods of heavy fog, especially along the coast, are frequent, and low clouds, often referred to as high fog, are a characteristic climate feature. Annual average humidity is 70% at the coast and 57% in the eastern portions of the SCAB.

Wind
Wind patterns across the south coastal region are characterized by westerly or southwesterly onshore winds during the day and by easterly or northeasterly breezes at night. Wind speed is higher during the dry summer months than during the rainy winter.

Between periods of wind, air stagnation may occur in both the morning and evening hours. Air stagnation is one of the critical determinants of air quality conditions on any given day. During the winter and fall, surface high-pressure systems over the SCAB, combined with other meteorological conditions, can result in very strong, downslope Santa Ana winds. These winds normally continue a few days before predominant meteorological conditions are reestablished.

The mountain ranges to the east affect the diffusion of pollutants by inhibiting the eastward transport of pollutants. Air quality in the SCAB generally ranges from fair to poor and is similar to air quality in most of coastal Southern California. The entire region experiences heavy concentration of air pollutants during prolonged periods of stable atmospheric conditions.

Inversions
Under ideal meteorological conditions and irrespective of topography, pollutants emitted into the air mix and disperse into the upper atmosphere. However, the Southern California region frequently experiences temperature inversions in which pollutants are trapped and accumulate close to the ground. The inversion, a layer of warm, dry air overlaying cool, moist marine air, is a normal condition in coastal Southern California. The cool, damp, and hazy sea air capped by coastal clouds is heavier than the warm, clear air, which acts as a lid through which the cooler marine layer cannot rise. The height of the inversion is important in determining pollutant concentration. When the inversion is approximately 2,500 feet above mean sea level (amsl), the sea breezes carry the pollutants inland to escape over the mountain slopes or through the passes. At a height of 1,200 feet above mean sea level, the terrain prevents the pollutants from entering the upper atmosphere, resulting in the pollutants settling in the foothill communities. Below 1,200 feet above mean sea level, the inversion puts a tight lid on pollutants, concentrating them in a shallow layer

2.0 Air Quality
Impact Sciences, Inc. 6 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
over the entire coastal basin. Usually, inversions are lower before sunrise than during the daylight hours.

Mixing heights for inversions are lower in the summer and inversions are more persistent, being partly responsible for the high levels of ozone (O3) observed during summer months in the SCAB. Smog in Southern California is generally the result of these temperature inversions combining with coastal day winds and local mountains to contain the pollutants for long periods, allowing them to form secondary pollutants by reacting in the presence of sunlight. The basin has a limited ability to disperse these pollutants due to typically low wind speeds and the surrounding mountain ranges.

Air Pollutants of Concern
Criteria air pollutants are defined as pollutants for which the federal and state governments have established ambient air quality standards for outdoor concentrations. The federal and state standards have been set at levels above which concentrations could be harmful to human health and welfare. These standards are designed to protect the most sensitive persons such as children, pregnant women, and the elderly, from illness or discomfort. Criteria air pollutants include ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), particulate matter 2.5 microns or less in diameter (PM2.5), particulate matter ten microns or less in diameter (PM10), and lead (Pb). Note that reactive organic gases (ROGs), which are also known as reactive organic compounds (ROCs) or volatile organic compounds (VOCs), and nitrogen oxides (NOx) are not classified as criteria pollutants. However, ROGs and NOx are widely emitted from land development projects and participate in photochemical reactions in the atmosphere to form O3; therefore, NOx and ROGs are relevant to the proposed Project and are of concern in the air basin and are listed below along with the criteria pollutants. Sources and health effects commonly associated with criteria pollutants are summarized in Table 1, Criteria Pollutants Summary of Common Sources and Effects.

2.2 AMBIENT AIR QUALITY
Criteria Air Pollutant Monitoring Data
Ambient air quality in Santa Clarita can be inferred from ambient air quality measurements conducted at nearby air quality monitoring stations. Existing levels of ambient air quality and historical trends and projections are documented by measurements made by the t SCAQMD, the air pollution regulatory agency in the SCAB regions maintains air quality monitoring stations which process ambient air quality measurements.

The purpose of the monitoring station is to measure ambient concentrations of pollutants and determine whether ambient air quality meets the National Ambient Air Quality Standards (NAAQS) and the California Ambient Air Quality Standards (CAAQS). Ozone and particulate matter (PM10 and PM2.5) are pollutants of particular concern in the SCAB. The monitoring station located closest to the Project site and most representative of air quality is the Santa Clarita-Placerita station, located at 22224 Placerita Canyon Road approximately 1.52 miles to the northwest (SCAQMD Station No. 090). Ambient emission concentrations vary due to localized variations in emissions sources and climate and should be considered “generally” representative of ambient concentrations near the Project site. The Santa Clarita-Placerita station monitors O3, NO2, CO, and PM10. Particulate matter 2.5 microns in diameter or less (PM2.5) is not measured at the Santa Clarita-Placerita station. The nearest station to the Project site measuring PM2.5 is

2.0 Air Quality

the Reseda station, which is located approximately 11.24 miles south of the Project site (SCAQMD Station No. 074). The air quality data monitored at the Santa Clarita-Placerita and Reseda stations are presented in Table 2, Air Monitoring Station Ambient Pollutant Concentrations.

The attainment status for the SCAB region is included in Table 3, Attainment Status of Criteria Pollutants in the South Coast Air Basin. Areas that meet ambient air quality standards are classified as attainment areas, while areas that do not meet these standards are classified as nonattainment areas. The SCAB region is designated as a nonattainment area for federal ozone, PM2.5, and lead standards and are designated as nonattainment for state ozone, PM10, and PM2.5 standards.

However, all stations in the Basin, including the near-source monitoring in Los Angeles County, have remained below the lead NAAQS for the 2012 through 2015 period. The SCAQMD will request that the U.S. EPA re-designated the Los Angeles County portion of the Basin as attainment for lead.

Toxic Air Contaminants
In addition to the criteria pollutants discussed above, toxic air contaminants (TACs) are another group of pollutants of concern. TACs are considered either carcinogenic or noncarcinogenic based on the nature of the health effects associated with exposure to the pollutant. For regulatory purposes, carcinogenic TACs are assumed to have no safe threshold below which health impacts would not occur, and cancer risk is expressed as excess cancer cases per one million exposed individuals. Noncarcinogenic TACs differ in that there is generally assumed to be a safe level of exposure below which no negative health impact is believed to occur. These levels are determined on a pollutant-by-pollutant basis.

There are many different types of TACs, with varying degrees of toxicity. Sources of TACs include industrial processes, such as petroleum refining and chrome-plating operations; commercial operations, such as gasoline stations and dry cleaners; and motor vehicle exhaust. Public exposure to TACs can result from emissions from normal operations, as well as from accidental releases of hazardous materials during upset conditions. The health effects associated with TACs are quite diverse and generally are assessed locally, rather than regionally. TACs can cause long-term health effects such as cancer, birth defects, neurological damage, asthma, bronchitis, or genetic damage, or short-term acute affects such as eye watering, respiratory irritation (a cough), running nose, throat pain, and headaches.

2.0 Air Quality
Impact Sciences, Inc. 10 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
To date, CARB has designated 244 compounds as TACs. Additionally, CARB has implemented control measures for a number of compounds that pose high risks and show potential for effective control. The majority of the estimated health risks from TACs can be attributed to a relatively few compounds.2 CARB identified diesel particulate matter (DPM) as a TAC. DPM differs from other TACs in that it is not a single substance but rather a complex mixture of hundreds of substances. Diesel exhaust is a complex mixture of particulates and gases produced when an engine burns diesel fuel. DPM is a concern because it causes lung cancer; many compounds found in diesel exhaust are carcinogenic. DPM includes the particlephase constituents in diesel exhaust. The chemical composition and particle sizes of DPM vary between different engine types (heavy-duty, light-duty), engine operating conditions (idle, accelerate, decelerate), fuel formulations (high/low sulfur fuel), and the year of the engine. Some short-term (acute) effects of diesel exhaust include eye, nose, throat, and lung irritation, and diesel exhaust can cause coughs, headaches, lightheadedness, and nausea. DPM poses the greatest health risk among the TACs. Almost all diesel exhaust particle mass is 10 microns or less in diameter. Because of their extremely small size, these particles can be inhaled and eventually trapped in the bronchial and alveolar regions of the lung.

Sensitive Receptors
Some land uses are considered more sensitive to air pollution than others due to the types of population groups or activities involved. Sensitive population groups include children, the elderly, the acutely ill, and the chronically ill, especially those with cardiovascular diseases.3 Residential areas are considered sensitive receptors to air pollutions because residents (including children and the elderly) tend to be at home for extended periods of time, resulting in sustained exposure to any pollutants present. Children are considered more susceptible to health effects of air pollution due to their immature immune systems and developing organs.4 As such, schools are also considered sensitive receptors, as children are present for extended durations and engage in regular outdoor activities.

Recreational land uses are considered moderately sensitive to air pollution. Although exposure periods are generally short, exercise places a high demand on respiratory functions, which can be impaired by air pollution. In addition, noticeable air pollution can detract from the enjoyment of recreation. The closest residential areas are located approximately 800 feet to the northeast of the Project site. 2 California Air Resources Board. CARB Identified Toxic Air Contaminants. Available online at:

2.3 REGULATORY FRAMEWORK
Federal
Clean Air Act
The Clean Air Act (CAA) of 1970 and the CAA Amendments of 1971 required the U.S. Environmental Protection Agency (EPA) to establish NAAQS, with states retaining the option to adopt more stringent standards or to include other specific pollutants. On April 2, 2007, the Supreme Court found that carbon dioxide is an air pollutant covered by the CAA; however, no NAAQS have been established for carbon dioxide.

These standards are the levels of air quality considered safe, with an adequate margin of safety, to protect the public health and welfare. They are designed to protect those “sensitive receptors” most susceptible to further respiratory distress such as asthmatics, the elderly, very young children, people already weakened by other disease or illness, and persons engaged in strenuous work or exercise. Healthy adults can tolerate occasional exposure to air pollutant concentrations considerably above these minimum standards before adverse effects are observed.

The EPA has classified air basins (or portions thereof) as being in attainment, nonattainment, or unclassified for each criteria air pollutant, based on whether or not the NAAQS have been achieved. If an area is designated unclassified, it is because inadequate air quality data were available as a basis for a nonattainment or attainment designations. Table 3 lists the federal attainment status of the SCAB for the criteria pollutants.

National Emissions Standards for Hazardous Air Pollutants Program Under federal law, 187 substances are currently listed as hazardous air pollutants (HAPs). Major sources of specific HAPs are subject to the requirements of the National Emissions Standards for Hazardous Air Pollutants (NESHAPS) program. The EPA is establishing regulatory schemes for specific source categories and requires implementation of the Maximum Achievable Control Technologies (MACT) for major sources of HAPs in each source category. State law has established the framework for California’s TAC identification and control program, which is generally more stringent than the federal program and is aimed at HAPs that are a problem is California. The state has formally identified 244 substances as TACs and is adopting appropriate control measures for each. Once adopted at the state level, each air district will be required to adopt a measure that is equally or more stringent.

2.0 Air Quality
Impact Sciences, Inc. 12 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
National Ambient Air Quality Standards
The federal CAA required the U.S. EPA to establish NAAQS. The NAAQS set primary standards and secondary standards for specific air pollutants. Primary standards define limits for the intention of protecting public health, which include sensitive populations such as asthmatics, children, and the elderly.

Secondary Standards define limits to protect public welfare to include protection against decreased visibility, damage to animals, crops, vegetation, and buildings. A summary of the federal ambient air quality standards is shown in Table 4, National Ambient Air Quality Standards.

State
California Clean Air Act of 1988
The California CAA of 1988 (CCAA) allows states to adopt ambient air quality standards and other regulations provided that they are at least as stringent as federal standards. The California Air Resources Board (CARB), a part of the California Environmental Protection Agency (Cal EPA), is responsible for the coordination and administration of both federal and state air pollution control programs within California, including setting the CAAQS. The CCAA, amended in 1992, requires all air quality management districts (AQMDs) in the state to achieve and maintain the CAAQS. The CAAQS are generally stricter than national standards for the same pollutants and has also established state standards for sulfates, hydrogen sulfide,

2.0 Air Quality
Impact Sciences, Inc. 13 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
vinyl chloride, and visibility-reducing particles, for which there are no national standards. CARB also conducts research, compiles emission inventories, develops suggested control measures, and provides oversight of local programs. CARB also has primary responsibility for the development of California’s State Implementation Plan (SIP), for which it works closely with the federal government and the local air districts.

California Ambient Air Quality Standards
The federal CAA permits states to adopt additional or more protective air quality standards if needed.

California has set standards for certain pollutants, such as particulate matter and ozone, which are more protective of public health than respective federal standards. California has also set standards for some pollutants that are not addressed by federal standards. The state standards for ambient air quality are summarized in Table 5, California Ambient Air Quality Standards.

California State Implementation Plan
The federal CAA (and its subsequent amendments) requires each state to prepare an air quality control plan referred to as a State Implementation Plan (SIP). The SIP is a living document that is periodically

2.0 Air Quality
Impact Sciences, Inc. 14 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
modified to reflect the latest emissions inventories, plans, and rules and regulations of air basins as reported by the agencies with jurisdiction over them. The CAA Amendments dictate that states containing areas violating the NAAQS revise their SIPs to include extra control measures to reduce air pollution. The SIP includes strategies and control measures to attain the NAAQS by deadlines established by the CAA. The EPA has the responsibility to review all SIPs to determine if they conform to the requirements of the CAA.

State law makes CARB the lead agency for all purposes related to the SIP. Local air districts and other agencies prepare SIP elements and submit them to CARB for review and approval. CARB then forwards SIP revisions to the EPA for approval and publication in the Federal Register. The 2016 Air Quality Management Plan (2016 AQMP) is the SIP for SCAB. The 2016 AQMP is a regional blueprint for achieving air quality standards and healthful air in the SCAB and those portions of the Salton Sea Air Basin (SSAB) that are under the SCAQMD’s jurisdictions. The 2016 AQMP represents a new approach, focusing on available, proven, and cost-effective alternatives to traditional strategies, while seeking to achieve multiple goals in partnerships with other entities promoting reductions in greenhouse gases and toxic risk, as well as efficiencies in energy use, transportation, and goods movement. The most effective way to reduce air pollution impacts is to reduce emissions from mobile sources. The AQMP relies on regional and multi-level partnerships of governmental agencies at the federal, state, regional, and local level. Those agencies (EPA, CARB, local governments, Southern California Association of Governments [SCAG] and the SCAQMD) are the primary agencies that implement the AQMP programs. The 2016 AQMP incorporates the latest scientific and technical information and planning assumptions, including SCAG’s 2016-2035 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), updated emission inventory methodologies for various source categories, and SCAG’s latest growth forecasts. The 2016 AQMP includes integrated strategies and measures to meet the NAAQS.

On September 3, 2020, SCAG’s Regional Council unanimously voted to approve and fully adopt Connect SoCal (2020-2045 RTP/SCS). However, the forecasts and measures in the plan have not been incorporated into any applicable air quality plan for the region.5
California Air Toxics “Hot Spots” Information and Assessment Act (AB 2588) The California Air Toxics Program is supplemented by the Air Toxics “Hot Spots” program, which became law (AB 2588, Statutes of 1987) in 1987. In 1992, the AB 2588 program was amended by Senate Bill 1731 to require facilities that pose a significant health risk to the community to perform a risk reduction audit and reduce their emissions through implementation of a risk management plan. Under this program, which is required under the Air Toxics “Hot Spots” Information and Assessment Act (Section 44363 of the California 5 Southern California Association of Governments. Adopted Final Connect SoCal (2020-2045 RTP/SCS). Available online at: https://scag.ca.gov/read-plan-adopted-final-plan.

Health and Safety Code), facilities are required to report their air toxics emissions, assess health risks, and notify nearby residents and workers of significant risks when present.

Typically, land development projects generate diesel emissions from construction vehicles during the construction phase, as well as some diesel emissions from small trucks during the operational phase. Diesel exhaust is mainly composed of particulate matter and gases, which contain potential cancer-causing substances. Emissions from diesel engines currently include over 40 substances that are listed by EPA as hazardous air pollutants and by CARB as TACs. On August 27, 1998, CARB identified particulate matter in diesel exhaust as a TAC, based on data linking diesel particulate emissions to increased risks of lung cancer and respiratory disease.6
In March 2015, the OEHHA adopted “The Air Toxics Hot Spots Program Guidance Manual for Preparation of Health Risk Assessments” in accordance with the Health and Safety Code, Section 44300. The Final Guidance Manual incorporates the scientific basis from three earlier developed Technical Support Documents to assess risk from exposure to facility emissions. The 2015 OEHHA Final Guidance has key changes including greater age sensitivity in particular for children, decreased exposure durations, and higher breathing rate profiles. Because cancer risk could be up to three times greater using this new guidance, it may result in greater mitigation requirements, more agency backlog, and increased difficulty in getting air permits. Regardless of the change in calculation methodology, actual emissions and cancer risk within South Coast Air Basin has declined by more than 50% since 2005.

The CARB provides a computer program, the Hot Spots Analysis and Reporting Program (HARP), to assist in a coherent and consistent preparation of an HRA. HARP2, an update to HARP, was released in March 2015. HARP2 has a more refined risk characterization in HRA and CEQA documents and incorporates the 2015 OEHHA Final Guidance.

permits for stationary sources of air pollutants, inspecting stationary sources of air pollutants, responding to citizen complaints, monitoring ambient air quality and meteorological conditions, awarding grants to reduce motor vehicle emissions, and conducting public education campaigns, as well as many other activities. All projects are subject to SCAQMD rules and regulations in effect at the time of construction.

SCAQMD Rules and Regulations
The following is a list of noteworthy SCAQMD rules that are required of construction activities associated with the proposed Project:
x Rule 402 (Nuisance) – This rule prohibits the discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health, or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property. This rule does not apply to odors emanating from agricultural operations necessary for the growing of crops or the raising of fowl or animals. x Rule 403 (Fugitive Dust) – This rule requires fugitive dust sources to implement best available control measures for all sources, and all forms of visible particulate matter are prohibited from crossing any property line. This rule is intended to reduce PM10 emissions from any transportation, handling, construction, or storage activity that has the potential to generate fugitive dust. PM10 suppression techniques are summarized below.
Portions of a construction site to remain inactive longer than a period of three months will be seeded and watered until grass cover is grown or otherwise stabilized. All on-site roads will be paved as soon as feasible or watered periodically or chemically stabilized. All material transported off-site will be either sufficiently watered or securely covered to prevent excessive amounts of dust.
The area disturbed by clearing, grading, earthmoving, or excavation operations will be minimized at all times.
Where vehicles leave a construction site and enter adjacent public streets, the streets will be swept daily or washed down at the end of the work day to remove soil tracked onto the paved surface. x Rule 1113 (Architectural Coatings) – This rule requires manufacturers, distributors, and end-uses of architectural and industrial maintenance coatings to reduce ROG emissions from the use of these coatings, primarily by placing limits on the ROG content of various coating categories.

2.0 Air Quality
Impact Sciences, Inc. 17 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
x Rule 445 (Wood-Burning Devices) – The purpose of this rule is to reduce the emission of particulate matter from wood-burning devices and establish contingency measures for applicable ozone standards for the reduction of volatile organic compounds.

The rule requires that any new residential or commercial development that begins construction on or after March 9, 2009, only install gaseous-fueled fireplaces and stoves.7 Local

2.4 THRESHOLDS AND METHODOLOGY
Thresholds of Significance
The impact analysis provided below is based on the application of the following California Environmental Quality Act (CEQA) Guidelines Appendix G, which indicates that a Project would have a significant impact on air quality if it would:

1. Conflict with or obstruct implementation of any applicable air quality plan.

2. Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard.

3. Expose sensitive receptors to substantial pollutant concentrations.

4. Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

The significance criteria established by the applicable air quality management or air pollution control district (SCAQMD) may be relied upon to make the above determinations. According to the SCAQMD, an air quality impact is considered significant if the proposed Project would violate any ambient air quality standard, contribute substantially to an existing or projected air quality violation, or expose sensitive receptors to substantial pollutant concentrations. The SCAQMD has established thresholds of significance for air quality for construction and operational activities of land use development projects, shown in Table 6, South Coast AQMD Regional Significance Thresholds.

CO Hotspot Analysis
In addition to the daily thresholds listed above, the proposed Project area would also be subject to the ambient air quality standards, through an analysis of localized CO impacts. The California 1-hour and 8- hour CO standards are:
x 1-hour = 20 parts per million
x 8-hour = 9 parts per million

2.0 Air Quality
Impact Sciences, Inc. 20 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
The significance of localized impacts depends on whether ambient CO levels in the vicinity of the Project site are above state and federal CO standards. The SCAB region is designated as attainment under the 1- hour and 8-hour standards (see Table 3).

Localized Significance Thresholds
In addition to regional emissions and the CO hotspot analysis, the SCAQMD has developed a set of mass emissions rate look-up tables that can be used to evaluate localized impacts that may result from construction and operational-period emissions called localized significance thresholds (LSTs). If the on-site emissions from proposed construction activities are below the emission levels found in the LST mass rate look-up tables for the Project site receptor area (SRA), then emissions would not have the potential to cause a significant localized air quality impact. When quantifying mass emissions for LST analysis, only emissions that occur on site are considered. Consistent with SCAQMD LST guidance, emissions from offsite delivery hauling trucks, or employee trips are not considered in the evaluation of localized impacts.

The SCAQMD has developed localized significance thresholds (LST) for construction areas that are one, two, and five acres in size to simplify the evaluation of localized emissions. LSTs represent the maximum emissions from a project that are not expected to cause or contribute to an exceedance of the applicable federal or State ambient air quality standard. LSTs are provided for each source receptor area (SRA) and various distances from the source of emissions. As described previously, the nearest air quality sensitive receptors to the Project site are residences located approximately 800 feet (245 meters) to the northeast.

In the case of this analysis, the Project site is located within SRA 13 – Santa Clarita Valley with receptors located approximately 213 meters to the northeast. The CalEEMod User’s Guide (Appendix A: Calculation Details for CalEEMod) states the applicable LST should be based on the equipment list for each construction phase and calculated according to the anticipated maximum number of acres a given piece of equipment can pass over in an 8-hour workday.

Based on the Project’s construction assumptions, approximately 4 acres per day would be disturbed during the grading phase. The LSTs for a 4-acre site in SRA 13 with sensitive receptors located approximately 200 meters were calculated per r SCAQMD Linear Regression Methodology and utilized for the grading phase.

Table 7, Construction Local Significance Thresholds – Pounds per Day, shows the construction LST screening threshold for sensitive receptors located approximately 200 meters from the Project site.

Methodology
Air quality impacts were evaluated in accordance with the methodologies recommended by CARB and the SCAQMD. Where criteria air pollutant quantification was required, emissions modeled using the California Emissions Estimator Model version 2020.4.0 (CalEEMod). CalEEMod is a statewide land use emissions computer model designed to quantify potential criteria pollutant emissions associated with both construction and operations from a variety of land use projects.

2.5 PROJECT IMPACTS
AQ Impact 1 Would implementation of the proposed Project conflict with or obstruct implementation of any applicable air quality plan? (Less than Significant).

As part of its enforcement responsibilities, the EPA requires each state with nonattainment areas to prepare and submit a SIP that demonstrates the means to attain the federal standards. The SIP must integrate federal, state, and local plan components and regulations to identify specific measures to reduce pollution in nonattainment areas, using a combination of performance standards and market-based programs.

Similarly, under state law, the CCAA requires an air quality attainment plan to be prepared for areas designated as nonattainment with regard to the federal and state ambient air quality standards. Air quality attainment plans outline emissions limits and control measures to achieve and maintain these standards by the earliest practical date.

2.0 Air Quality
Impact Sciences, Inc. 22 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
Drafted by the SCAQMD, the 2016 AQMP8 was developed in effort with CARB, SCAG, and the U.S. EPA to establish a program of rules and regulations to reduce air pollutant emissions to achieves CAAQS and NAAQS. The plan’s pollutant control strategies are based on SCAG’s 2016 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). While SCAG adopted the updated 2020-2045 RTP/SCS in September 2020, it has not been incorporated into an applicable air quality plan.

Criteria for determining consistency with the AQMP are defined in Chapter 12, Section 12.2 and Section

12.3 of the SCAQMD’s 1993 CEQA Air Quality Handbook, and include the following:
x Consistency Criterion No. 1: The proposed Project will not result in an increase in the frequency or severity of an existing air quality violation, or cause or contribute to new violations, or delay the timely attainment of air quality standards or the interim emissions reductions specified in the AQMP. x Consistency Criterion No. 2: The proposed Project will not exceed the assumptions in the AQMP or increments based on the years of the Project build-out phase.

The violations to which Consistency Criterion No. 1 refers are the CAAQS and the NAAQS. As evaluated under Impacts 2 below, the Project would not exceed the short-term construction standards or long-term operational standards and, thus, would not have the potential to violate any air quality standards (see Table 8 and Table 9). Thus, the proposed Project would be consistent with first criterion.

Concerning Consistency Criterion No. 2, the 2016 AQMP contains air pollutant reduction strategies based on SCAG’s growth forecasts, and SCAG’s growth forecasts were defined in consultation with local governments and with reference to local general plans. The proposed Project would not alter the local population or other SCAG’s regional growth forecasts.9 In addition,the proposed Project is consistent with the land use designation and development density in the City of Santa Clarita General Plan. Therefore, the proposed Project would not have the potential to alter local or regional growth projections used by the SCAMQD to develop the 2016 AQMP. Thus, the proposed Project is also consistent with the second criterion. As the Project is consistent with Criterion Nos. 1 and 2, the Project would not conflict with or obstruct implementation of any applicable air quality plan, and this impact is less than significant. 8 South Coast Air Quality Management District. 2016.

See also CalEEMod modeling in Attachment A.

2.0 Air Quality
Impact Sciences, Inc. 23 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
AQ Impact 2 Would implementation of the proposed Project result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard? (Less than Significant).

A project may have a significant impact if project-related emissions would result in a cumulatively considerable net increase for an criteria pollutant for which the region in nonattainment under applicable federal or state ambient air quality standards. The cumulative analysis of air quality impacts follows the SCAQMD’s guidance such that construction or operational project emissions will be considered cumulatively considerable if project-specific emissions exceed an applicable SCAQMD recommended daily threshold.

Regional Construction Significance Analysis
Construction associated with the proposed Project would generate short-term emissions of criteria air pollutants. The criteria pollutants of primary concern within the Project area include ozone-precursor pollutants (i.e., ROG and NOx), PM10, and PM2.5. Construction-generated emissions are short term and of temporary duration, lasting only as long as construction activities occur, but would be considered a significant air quality impact if the volume of pollutants generated exceeds the SCAQMD’s thresholds of significance.

Construction results in the temporary generation of emissions resulting from site grading and excavation, road paving, motor vehicle exhaust associated with construction equipment and worker trips, and the movement of construction equipment, especially on unpaved surfaces. Emissions of airborne particulate matter are largely dependent on the amount of ground disturbance associated with site preparation activities as well as weather conditions and the appropriate application of water.

The duration of construction activities associated with the proposed Project is estimated to last approximately 17 months, beginning in May 2022 and ending in October 2023. Construction-generated emissions associated with the proposed Project were calculated using the SCAQMD- and CARB-approved CalEEMod model. CalEEMod is designed to estimate construction and operational emissions for land use development projects. The model incorporates typical construction requirements such as construction equipment, demolition debris, and hauling trips. The assumptions used in the CalEEMod model, including construction equipment usage and earthwork cut and fill of 192,889 cubic yards, were based on information provided by the Project applicant. No soil import or export is anticipated at this time. Predicted maximum daily construction-generated emissions for the proposed Project are summarized in Table 8, ConstructionRelated Criteria Pollutant and Precursor Emissions – Maximum Pounds per Day.

2.0 Air Quality
Impact Sciences, Inc. 24 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
During construction, the contractors are required to comply with SCAQMD Rule 402 (Nuisance) and Rule 403 (Fugitive Dust), among others, which assist in reducing short-term construction-related air pollutant emissions. Rule 402 prohibits emissions that would cause a public nuisance and Rule 403 requires fugitive dust sources to implement best available control measures for all sources, and all forms of visible particulate matter are prohibited from crossing any property line. The proposed Project would be subject to Rules 402, 403, and 113 described in the Regulatory Framework subsection above. As shown below, all criteria pollutant emissions would remain below their respective thresholds. Thus, the proposed Project would not result in a cumulatively considerable net increase of any criteria air pollutant for which the Project region is nonattainment under an applicable federal or state ambient air quality standard.

Note: Project emissions account for the reductions from SCAQMD Rule 403 (Fugitive Dust).

Regional Operational Significance Analysis
Project-generated emissions would be associated with motor vehicle use, energy use, and area sources, such as the use of natural-gas-fired appliances, landscape maintenance equipment, consumer cleaning products, and architectural coatings associated with the operation of the proposed Project. The operational emissions from the proposed Project were calculated within CalEEMod and the operational emissions were compared against SCAQMD regional thresholds to determine Project significance.

Emissions associated with vehicle travel depend on the year of analysis because emission control technology requirements are phased-in over time. Therefore, the earlier the year analyzed in the model the higher emission rates used by CalEEMod. The earliest year the Project could possibly be constructed and fully occupied would be 2023. Emissions associated with build-out later than 2023 would be lower, because newer vehicles have to meet increasingly more stringent emissions standards, while older, more polluting, vehicles are used less.

2.0 Air Quality
Impact Sciences, Inc. 25 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
Long-term operational emissions attributable to the proposed Project are summarized in Table 9, LongTerm Operational Emissions – Maximum Pounds per Day.

As shown in Table 8 and Table 9, the proposed Project’s construction and operational emissions would not exceed the SCAQMD’s thresholds for any criteria air pollutants. Therefore, impacts associated with regional construction and operational emissions from the Project would be less than significant.

Air Quality Health Impacts
On December 24, 2018, the California Supreme Court published its opinion on the Sierra Club et al. v. County of Fresno et. Al. (Case No. S219783) which determined that an environmental review must adequately analyze a project’s potential impacts and inform the public how its bare numbers translate to a potential adverse health impacts or explain how existing scientific constraints cannot translate the emissions numbers to the potential health impacts.

SCAB is in state non-attainment for PM2.5, PM10, and Ozone (O3) and federal non-attainment for PM2.5 and O3. Therefore, an increase in emissions of particulate matter or ozone precursors (ROG and NOx) has the potential to push the region further from reaching attainment status and, as a result, are the pollutants of greatest concern in the region. As noted in Table 8 and Table 9 above, the proposed Project will emit criteria air pollutants during construction and operation. However, the proposed Project will not exceed SCAQMD thresholds for ozone precursors (ROG and NOx), PM2.5, PM10, or any other criteria air pollutants, and will not result in a cumulatively significant impact for which the region is in nonattainment. This discussion focuses on the health effects from the pollutants for which the region is in nonattainment and why it is not feasible to provide an analysis to relate the emissions of ozone precursors from an individual project to likely health consequences.

Exposure to particulate matter can affect both a person’s lungs and heart and has been linked to a variety of health problems including aggravated asthma, decreased lung function, and increased respiratory symptoms. DPM is a type of particulate that is emitted from diesel engines and is estimated to cause approximately 70% of total known cancer risks related to air toxics in California.10 As discussed below, see Impact 3, the proposed Project would not result in an increased health risk as a result from exposure to DPM or other TACs. Further, since the proposed Project will not exceed SCAQMD regional thresholds for particulate matter, the Project will not result in a cumulatively significant impact to particulate matter in the region.

Exposure to O3 can cause respiratory irritation, lung damage, aggravate asthma, and may worsen existing chronic lung diseases such as emphysema and chronic bronchitis.11 O3 is formed in the atmosphere when heat and sunlight cause a chemical reaction between NOx and ROG emissions. NOx and ROG are referred to as ozone precursors and affect air quality on a regional scale. Health effects related to O3 are therefore the product of emissions generated by numerous sources throughout a region. Existing models have limited sensitivity to small changes in criteria pollutant concentrations, and, as such, translating projectgenerated criteria pollutants to specific health effects or additional days of nonattainment would produce meaningless results. In other words, the proposed Project’s less than significant increases in regional air pollution from criteria air pollutants would not have measurable effect on the human health implications of the Basin’s ambient air quality.

The Congressional Research service prepared the Background Ozone: Challenges in Science and Policy report for U.S. Congress which provides a summary of the scientific capabilities of measuring ozone and understanding the needs and improvements necessary to understand contributions from background sources. While this paper specifically addresses background concentrations of ozone and ozone modeling, it demonstrates the difficulty in assessing ozone and related health implications from any single source or project. According to the Congressional Research Service, currently there are several data and analytical challenges to reliably assess background ozone concentrations and to model ozone. First, the current understanding of the amount, location, and type of pollutant emissions from many types of sources is insufficient. Therefore, inventories typically provide estimation, which may not be precise enough for apportioning contributions. Second, meteorological data (i.e., wind speed, wind direction, temperature, cloud cover, humidity, etc.) is not currently measured at a fine enough spatial scale to adequately represent relevant weather processes. Third, data on pollutant concentrations are limited, which increases the 10 California Air Resources Board. Overview: Diesel Exhaust & Health. Available online at:

challenges of understanding ozone formation and movement. Fine spatial and temporal measurements are needed both horizontally across the surface and vertically to higher levels of the atmosphere. Finally, background ozone source contributions change by year, season, day, and hour and from location to location.12
While several models and tools are available to quantify emissions, these models are limited by a number of factors in their ability to determine health impacts of individual development projects. The U.S. EPA currently performs health impact assessments (HIAs) using the Community Multiscale Air Quality (CMAQ)13 model for pollutant transport modeling and Environmental Benefits Mapping and Analysis Program – Community Edition (BENMAP – CE) for health impact calculations.14 However, these models are designed to estimate health impacts over a large scale (e.g., city-wide, state-wide). In addition, the CMAQ model requires inputs such as regional sources of pollutants and global meteorological data, which are not readily accessible. In general, the current suite of available models is not able to accurately model concentrations or dispersion of ozone because they are regional models unable to provide accurate results for individual projects. If reliable ozone concentrations can be determined, there is also limitation on being able to correlate concentrations to related health effects.

The SCAQMD acknowledges that quantifying the health impacts from O3 is difficult. The 2012 Air Quality Management Plan determines that a reduction of 432 tons (864,000 pounds) per day of NOx and a reduction of 187 tons (374,000 pounds) per day of VOC would reduce O3 levels at the highest monitored site by only nine parts per billion.15 Meaning, large reductions in precursor emissions translate to incremental reductions in measured ozone. Therefore, quantifying O3 and related O3 health impacts caused by NOx or VOC emissions from relatively small projects (defined as projects with regional scope) is limited. Thus, as the proposed Project would not exceed SCAQMD thresholds for construction and operational air emissions, it can be reasonably concluded that the proposed Project would not have a measurable effect on the human health in the Basin, nor would it have implications for the ambient air quality. As a result, the proposed Project would have a less than significant impact for air quality health impacts. 12 Congressional Research Service. 2019.

AQ Impact 3 Would implementation of the proposed Project expose sensitive receptors to substantial air pollutant concentrations? (Less than Significant).

Localized Significance Thresholds
Construction
The nearest sensitive receptors are residential uses located approximately 800 feet northeast of the Project site. To identify impacts to sensitive receptors, the SCAQMD recommends addressing LSTs for construction.

LSTs were developed in response to SCAQMD Governing Boards’ Environmental Justice Enhancement Initiative (I-4). The SCAMQD provided the Final Localized Significance Threshold Methodology for guidance.

The LST methodology assists lead agencies in analyzing localized impacts associated with project-specific analysis.

Based on the Project’s construction assumptions, approximately 4 acres per day would be disturbed during the grading phase. The LSTs for a 4-acre site in SRA 13 with sensitive receptors located approximately 200 meters were calculated per SCAQMD Linear Regression Methodology and utilized for the grading phase.

The SCAQMD’s methodology states that “off-site mobile emissions from the Project should not be included in the emissions compared to LSTs.” Therefore, for purposes of the construction LST analysis, only emissions included in the CalEEMod “on-site” emissions outputs were considered. The nearest sensitive receptor to the Project site is a multi-family apartment complex approximately 800 feet northeast, or approximately 244 meters. LST screening thresholds are provided for distances to sensitive receptors of 25, 50, 100, 200, and 500 meters. Therefore, LSTs for receptors located at 200 meters were utilized in this analysis.

Table 10, Localized Significance of Construction Emissions – Maximum Pounds per Day, presents the proposed Project’s localized emissions during construction activity. As shown in Table 10, the on-site air pollutant emissions on the peak day of construction would not exceed the applicable LSTs. Therefore, the proposed Project’s localized air quality impacts would not expose sensitive receptors to substantial air pollutant concentrations. Impacts would be less than significant.

Note: Building Construction, Paving, and Architectural Coating phases will all overlap in 2023. The on-site maximum daily emissions during each phase were added together to provide the most conservative assessment of possible emissions on the proposed Project site.

Localized Operational Significance Analysis
As discussed previously, LSTs would apply to the operational phase of a project if the project includes stationary sources or attracts mobile sources that may spend long periods queuing and idling at the site.

For example, the LST methodology applies to operational projects such as warehouse/transfer facilities.16 As the Project would not include warehouse or transfer facilities, an operational analysis against the LST methodology is not applicable to the Project and a detailed analysis associated with on-site operational emissions is not necessary to determine these impacts would be less than significant.

Localized Air Quality Health Impacts
As evaluated above, the proposed Project’s air emissions would not exceed the SCAQMD’s LST thresholds.

Therefore, the Project would not cause or contribute to an exceedance of the most stringent applicable NAAQS or CAAQS for emissions of CO, NOx, PM10, or PM2.5. It should be noted that the ambient air quality standards are developed and represent levels at which the most susceptible persons are protected.

In other words, the ambient air quality standards are purposely set in a stringent manner to protect children, elderly, and those with existing and respiratory problems. Thus, air quality health impacts would be less than significant.

Impact Sciences, Inc. 30 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
Carbon Monoxide Hotspots
CO emissions are a function of vehicle idling time, meteorological conditions, and traffic flow. Under certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection may reach unhealthful levels (i.e., adversely affecting residents, school children, hospital patients, the elderly, etc.).

The SCAB is designated as an attainment/maintenance area for the federal CO standards and attainment area for state standards. CO emissions have declined in recent years even as VMT on urban and rural roads have increased nationwide. Estimated anthropogenic CO emissions have decreased 68% between 1990 and 2014. In 2014, mobile sources accounted for 82% of the nation’s total anthropogenic CO emissions.17 Three major control programs have contributed to the reduced per-vehicle CO emissions: exhaust standards, cleaner burning fuels, and motor vehicle inspection/maintenance programs.

According to the SCAQMD CEQA Air Quality Handbook, a potential CO hotspot may occur at any location where the background CO concentration already exceeds 9.0 ppm, the CAAQS for 8-hour for CO. As previously discussed, the site is located in SRA 13, Santa Clarita Valley. Communities within SRAs are expected to have similar climatology and ambient air pollutant concentrations. The monitoring station representative of SRA 13 is the Santa Clarita-Placerita station, which is located approximately 1.52 miles northwest of the site. Within the most recent three years for which measurements are available, the highest CO concentration at the Santa Clarita-Placerita station was measured at 1.2 ppm in 2019. Based on these measured concentrations, CO concentrations in SRA 13 are substantially below the California one-hour or eight-hour CO standards of 20 or 9.0 ppm, respectively. Accordingly, with the steadily decreasing CO emissions from vehicles, even very busy intersections do not result in exceedances of the CO standard.

Therefore, the Project would not have the potential to cause or contribute to an exceedance of the California one-hour or eight-hour CO standards of 20 or 9.0 ppm, respectively. Impacts with respect to localized CO concentrations would be less than significant
Diesel Particulate Matter
Project Construction
Construction would result in the generation of DPM emissions from the use of off-road diesel equipment required for grading and excavation, paving, and other construction activities. The amount to which the receptors are exposed (a function of concentration and duration of exposure) is the primary factor used to 17 U.S. Environmental Protection Agency. 2018.

determine health risk (i.e., potential exposure to TAC emission levels that exceed applicable standards).

Health-related risks associated with diesel-exhaust emissions are primarily linked to long-term exposure and the associated risk of contracting cancer.

The use of diesel-powered construction equipment would be temporary and episodic (i.e., intermittent during the Project’s anticipated 17-month construction period). The duration of exposure would be short and exhaust from construction equipment dissipates rapidly. Current methodology for conducting health risk assessments is associated with long term exposure periods (9, 30, and 70 years). Therefore, short-term construction activities would not generate a significant health risk. In addition, the nearest air quality sensitive receptor is located approximately 800 feet from the Project site and thus exposure to sensitive populations would be limited.

Furthermore, construction would be subject to and would comply with California regulations limiting the idling of heavy-duty construction equipment to no more than 5-minutes, which would further reduce nearby sensitive receptors’ exposure to temporary and variable DPM emissions.18 For these reasons, DPM generated by construction activities, in and of itself, would not be expected to expose sensitive receptors to substantial amounts of air toxics and the proposed Project would have a less than significant impact.

Project Operation
The greatest potential during long-term operations for exposure to TACs is from the use of heavy-duty diesel trucks and stationary generators that use diesel fuel. Once operational, the majority of vehicle trips to the Project site would be from visitors and, as a result, the proposed Project would attract very few diesel truck trips. For these reasons, once operational, the proposed Project would not expose nearby sensitive receptors to substantial amounts of air toxics and the Project would have a less than significant impact.

AQ Impact 4 Would the proposed Project include sources that could create other emissions (such as those leading to odors) adversely affecting a substantial number of people? (Less than Significant).

The SCAQMD CEQA Air Quality Handbook (1993) identifies certain land uses as sources of odors. These land uses include agriculture (farming and livestock), wastewater treatment plants, food processing plants, chemical plants, composting facilities, refineries, landfills, dairies, and fiberglass molding. The proposed Project would not include any of the land uses that have been identified by the SCAQMD as odor sources. 18 California Air Resources Board. 2015.

Construction activities associated with the proposed Project may generate detectable odors from heavyduty equipment exhaust and architectural coatings. However, construction-related odors would be shortterm in nature and cease upon Project completion. In addition, the proposed Project would be required to comply with the California Code of Regulations, Title 13, sections 2449(d)(3) and 2485, which minimizes the idling time of construction equipment either by shutting it off when not in use or by reducing the time of idling to no more than five minutes. This would reduce the detectable odors from heavy-duty equipment exhaust. The proposed Project would also be required to comply with the SCAQMD Rule 1113 – Architectural Coating, which would minimize odor impacts from ROG emissions during architectural coating. Any odor impacts to existing adjacent land uses would be short-term and not substantial. As such, the Project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people. Impacts would be less than significant.

3.0 GREENHOUSE GAS

3.1 GREENHOUSE GAS SETTING
Global climate change refers to any significant change in climate measurements, such as temperature, precipitation, or wind, lasting for an extended period (i.e., decades or longer).19 Climate change may result from:
x Natural factors, such as changes in the sun’s intensity or slow changes in the Earth’s orbit around the sun;
x Natural processes within the climate system (e.g., changes in ocean circulation, reduction in sunlight from the addition of GHG and other gases to the atmosphere from volcanic eruptions); and x Human activities that change the atmosphere’s composition (e.g., through burning fossil fuels) and the land surface (e.g., deforestation, reforestation, urbanization, desertification).

In recent decades, changes in climate have caused impacts on natural and human systems on all continents and across the oceans. Impacts are due to observed climate change, irrespective of its cause, indicating the sensitivity of natural and human systems to changing climate.20 Continuing changes to the global climate system and ecosystems, and to California, are projected to include:
x Rapidly diminishing sea ice and mountain snowpack levels, thereby increasing sea levels and sea surface evaporation rates with a corresponding increase in tropospheric water vapor due to the atmosphere’s ability to hold more water vapor at higher temperatures;21 x Rising average global sea levels primarily due to thermal expansion and the melting of glaciers, ice caps, and ice sheets;
x Changing weather patterns, including changes to precipitation, ocean salinity, and wind patterns, and more energetic aspects of extreme weather, including droughts, heavy precipitation, heat waves, extreme cold, and the intensity of tropical cyclones;

x Changing levels in snowpack, river flow and sea levels indicating that climate change is already affecting California’s water resources,22
x Dry seasons that start earlier and end later, evoking more frequent and intense wildland fires,23 and x Increasing demand for electricity due to rising temperatures.24 The natural process through which heat is retained in the troposphere25 is called the “greenhouse effect.” Various gases in the Earth’s atmosphere, classified as atmospheric greenhouse gases, play a critical role in determining the Earth’s surface temperature. Solar radiation enters Earth’s atmosphere as short-wave radiation. It travels through the atmosphere without warming it and is absorbed by the Earth’s surface.

When the Earth re-emits this radiation back toward space, the radiation changes to long wave radiation.

GHGs are transparent to incoming short wave solar radiation but absorb outgoing long wave radiation. As a result, radiation that otherwise would escape back into space is now retained, warming the atmosphere.

This phenomenon is known as the greenhouse effect.

Greenhouse Gas Compounds
Global warming potential was developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2). CO2, by definition, has a GWP of 1 regardless of the time period used, because it is the gas being used as the reference. CO2 remains in the climate system for a very long time: CO2 emissions cause increases in atmospheric concentrations of CO2 that will last thousands of years. Methane (CH4) is estimated to have a GWP of 28–36 over 100 years.

CH4 emitted today lasts about a decade on average, which is much less time than CO2. But CH4 also absorbs much more energy than CO2. The net effect of the shorter lifetime and higher energy absorption is reflected in the GWP. Nitrous Oxide (N2O) has a GWP 265–298 times that of CO2 for a 100-year timescale. N2O emitted today remains in the atmosphere for more than 100 years, on average. Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) are sometimes called high-GWP gases because, for a given amount of mass, they trap 22 California Environmental Protection Agency (Cal EPA). 2010.

substantially more heat than CO2. (The GWPs for these gases can be in the thousands or tens of thousands.)26
California State law defines GHGs to include the following six compounds:
x Carbon Dioxide (CO2) is released to the atmosphere when solid waste, fossil fuels (oil, natural gas, and coal), and wood and wood products are burned. CO2 emissions from motor vehicles occur during operation of vehicles and operation of air conditioning systems. x Methane (CH4) is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic waste in solid waste landfills, raising livestock, natural gas and petroleum systems, stationary and mobile combustion, and wastewater treatment. x Nitrous Oxide (N2O) is emitted during agricultural and industrial activities, as well as during combustion of solid waste and fossil fuels. N2O is also emitted from motor vehicles generally occurring from operation of vehicles.
x Hydrofluorocarbons (HFCs) are one of several GWP gases that are not naturally occurring and are generated from industrial processes. HFC (refrigerant) emissions from vehicle air conditioning systems occur due to leakage, losses during recharging, or release from scrapping vehicles at end of their useful life.
x Perfluorocarbons (PFCs) are another high GWP gas that are not naturally occurring and are generated in a variety of industrial processes. Emissions of PFCs are generally negligible from motor vehicles. x Sulfur Hexafluoride (SF6) is another high GWP gas that is not naturally occurring and is generated in a variety of industrial processes. Emissions of SF6 are generally negligible from motor vehicles.

Land uses at this site associated with GHG emissions are from vehicle trips to the site, energy sources for electrical supply to the site and area sources such as the use of landscape maintenance equipment, consumer cleaning products, and architectural coatings. GHG emissions from the existing uses were calculated using CalEEMod (see Impact 1).

3.3 REGULATORY FRAMEWORK
Federal
Paris Climate Agreement
The Paris Climate Agreement is an international treaty on climate change adopted on December 12, 2015.

The goal of the agreement is to limit global warming to 1.5 degrees Celsius as compared to pre-industrial levels. Countries will aim to reach global peaking of GHG emissions as soon as possible to achieve a climate neutral world by mid-century. In order to achieve these reductions, the Paris Climate Agreement works on a 5-year cycle of increasingly ambitious climate action carried out by countries. Therefore, by 2020, countries were required to submit their plans for climate action, known as nationally determined contributions. Additionally, the Agreement provides a framework for financial, technical and capacity building support to those countries who need it. Developed counties will take a lead in providing financial assistance to other countries since large scale investments are required for GHG mitigation and climate adaptation.27
The United States joined 190 other countries in the Paris Climate Agreement under the Obama administration in September 2016.28 Under the Trump administration, the former President announced his intention to withdraw from the Agreement in June 2017 and formally notified the United Nations in November 2019. However, the Agreement requires a year-long waiting period before a formal withdrawal will be recognized. As a result, the United States officially withdrew the Agreement in November 2020.29 However, on January 20, 2021, President Biden accepted and rejoined the Paris Climate Agreement.30 27 United Nations.

State
The state of California has implemented a series of greenhouse gas plans and policies aimed at reducing state greenhouse gas emissions. Measures applicable to the Project are summarized below:

Executive Order (EO) S-03-05
On June 1, 2005, EO S-03-05 was issued by Governor Schwarzenegger in order to set statewide emissions reduction standards. The order required the state to reduce GHG emissions to 1990 levels by 2020 and reduce GHG emissions to 80% below 1990 levels by 2050. EO S-3-05 also calls for the Secretary of California Environmental Protection Agency (Cal/EPA) to be responsible for coordination of state agencies and progress reporting.

Assembly Bill 32
Assembly Bill (AB) 32 (California Global Warming Solutions Act of 2006) was codified into law in 2006 and codified into law the 2020 GHG emissions targets set by EO S-03-05. AB 32 represents the first enforceable statewide program to limit GHG emissions from all major sectors with penalties for noncompliance.

Senate Bill 32
Senate Bill (SB) 32 was signed into law in 2015 and sets into law the mandated reduction targets set in EO B-30-15, which required a reduction in GHG emissions to 40% below the 1990 levels by 2030.

CARB’s 2017 Final Scoping Plan
The California Air Resources Board (CARB) in collaboration with over twenty state agencies issued a Final Scoping Plan in 2017 in order to set a framework for the state to meet the overall reduction goals set in SB

32. The 2017 Scoping Plan identified key sectors of the implementation strategy, which includes improvements in low carbon energy, industry, transportation sustainability, natural and working lands, waste management, and water. Through a combination of data synthesis and modeling, CARB determined that the target statewide 2030 emissions limit is 260 MMTCO2e, and that further commitments will need to be made to achieve an additional reduction of 50 MMTCO2e beyond current policies and programs. Key elements of the 2017 Update include a proposed 20% reduction in GHG emissions from refineries and an expansion of the Cap-and-Trade program to meet the aggressive 2030 GHG emissions goal.

SCAQMD Draft Guidance Regarding Interim CEQA GHG Significance Thresholds SCAQMD released draft guidance regarding interim CEQA GHG significance thresholds. In its October 2008 document, the SCAQMD proposed a 30% emission reduction target to determine significance for commercial/residential projects that emit greater than 3,000 metric tons per year. On December 5, 2008, the SCAQMD Governing Board adopted the staff proposal for an interim GHG significance threshold for stationary source/industrial projects where the SCAQMD is lead agency. However, SCAQMD has yet to adopt a GHG significance threshold for land use development projects (e.g., residential/commercial projects) and has formed a GHG Significance Threshold Working Group to further evaluate potential GHG significance thresholds. The draft tier thresholds recommended by the SCAQMD Working Group were never authorized as guidance for GHG analyses. These recommended thresholds are over a decade old; as a result, these thresholds were not utilized in this analysis.

SCAG 2020 Connect SoCal Plan RTP/SCS
On September 3, 2020, the Southern California Association of Governments (SCAG) Regional Council unanimously voted to approve and fully adopt Connect SoCal (2020-2045 Regional Transportation Plan/Sustainable Communities Strategy [RTP/SCS]).

Connect SoCal is a long-range visioning plan that builds upon and expands land use and transportation strategies established over several planning cycles to increase mobility options and achieve a more sustainable growth pattern. It charts a path toward a more mobile, sustainable and prosperous region by making connections between transportation networks, between planning strategies and between the people whole collaboration can improve the quality of life for Southern Californians. In addition, Connect SoCal is supported by a combination of transportation and land use strategies that outline how the region can achieve California’s greenhouse gas emission reduction goals and federal CAA requirements. The plan also strives to achieve broader regional objectives, such as the preservation of natural lands, improvement of public health, increased roadway safety, support for the region’s vital goods movement industries and more efficient use of resources.

City of Santa Clarita Climate Action Plan
The State of California requires all cities that create a new general plan or update their general plan document to consider its impacts on GHG emissions. In order to do so, cities must complete a CAP. The CAP must achieve the emission reduction goals outlined by the Global Warming Solutions Act of 2006 (AB 32). AB 32 requires that statewide GHG emissions must be reduced to 1990 levels by 2020. Measures identified in the City’s CAP will not only meet but exceed the state’s AB 32 GHG emission reduction mandate.31
In June 2011, the City Council adopted a new General Plan (referred to as One Valley One Vision), which is intended to guide growth and development within all portions of the Santa Clarita Valley. As noted above, Policy CO 8.1.1 of the City’s General Plan states the City shall create and adopt a CAP within 18 months of the adoption of the City’s General Plan Update that meets state requirements. Consistent with this policy, in January 2011, the City began the process of developing a CAP, with the Final CAP published 31 City of Santa Clarita. 2012. Climate Action Plan. Available online at:

Impact Sciences, Inc. 40 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
in August 2012. The CAP, part of the General Plan, serves as a component of the general plan document for the City to address GHG emissions. Using the goals, objectives, and policies of the General Plan as a starting point, the CAP identifies mitigation measures that can be quantified and translated into significant reductions in the GHG emissions by the year 2020. The development of a CAP begins with a premise that establishing a complete GHG emissions inventory within the City’s boundary is the critical foundation for the remainder of the project.

The CAP also defines a local threshold of significance for GHG emissions for project level submittals that trigger review by the CEQA. Because goals, objectives, and policies approved under the General Plan are forecast to meet the GHG emission reduction targets mandated by AB 32, development projects that are able to demonstrate consistency with the General Plan and zoning ordinance will by association demonstrate consistency with the CAP. However, the CAP is only certified through 2020.

Santa Clarita Building Standards Code
Section 25.01.010 in the Santa Clarita Municipal Code adopts by reference that certain code known and designated as the California Code of Regulations, Title 24, Part 11, further described as the 2016 California Green Building Standards Code, also referred to as the 2019 CalGreen Code, published by the California Building Standards Commission. Such code shall be and become the City of Santa Clarita Green Building Standards Code, regulating the planning, design, operation, construction, use and occupancy of every new building or structure to ensure buildings have a more positive environmental impact and encourage sustainable construction practices as specifically provided for therein.

3.4 THRESHOLDS AND METHODOLOGY
Thresholds of Significance
The impact analysis provided below is based on the application of the following CEQA Guidelines Appendix G, which indicates that a proposed Project would have a significant impact on GHG emissions if it would:
1) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment.
2) Conflict with an applicable plan, policy or regulations adopted for the purpose of reducing the emissions of greenhouse gas emissions.

3.0 Greenhouse Gas
Impact Sciences, Inc. 41 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
Methodology
GHG emissions and climate change were evaluated in accordance with Appendix G of the CEQA Guidelines. CEQA Guidelines Section 15064.4 states that, when making a determination with respect to the significance of a Project’s GHG emissions, a lead agency shall have discretion to determine whether to: (1) Use a model or methodology to quantify greenhouse gas emissions resulting from a project, and which model or methodology to use; and/or (2) Rely on a qualitative analysis or performance-based standards.

Section 15064.4 also states that a lead agency should consider the following factors when assessing the significance of the impact of GHG emissions on the environment: (1) The extent to which the project may increase or reduce greenhouse gas emissions as compared to the existing environmental setting; (2) Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project; and (3) The extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions.

GHG emissions were calculated in the same CalEEMod model used to determine the proposed Project’s criteria air pollutant emissions. Consistent with SCAQMD recommendations, construction emissions were amortized over a thirty-year period and added to the annual operational emissions to determine the proposed Project’s annual GHG emissions. Consistent with CEQA Guidelines Section 15064(h)(3), Project significance was determined based on the proposed Project’s consistency with an approved plan or mitigation program that provides specific requirements that will avoid or substantially lessen the cumulative problem within the geographic area of the proposed Project. The relevant adopted regulatory plans include CARB’s 2017 Scoping Plan, CALGreen, California Energy Code, SCAG’s 2020 Connect SoCal Plan, and the City’s General Plan. Although the City’s CAP is only a qualified plan through the year 2020, the following consistency analysis with the City’s CAP is included for informational purposes.

3.5 PROJECT IMPACTS
GHG Impact 1 Would implementation of the proposed Project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? (Less than Significant).

Both construction period and operational period activities would have the potential to generate GHG emissions.

Construction Emissions
The proposed Project would generate GHG emissions during temporary, short-term construction activities such as demolition, site preparation and grading, running of construction equipment engines, movement

3.0 Greenhouse Gas
Impact Sciences, Inc. 42 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
of on-site heavy-duty construction vehicles, hauling of materials to and from the site, asphalt paving, and construction worker motor vehicle trips.

Through CalEEMod, GHG emissions throughout proposed Project construction were calculated from offroad equipment usage, hauling vehicles, delivery, and worker trips to and from the site. The total GHG construction emissions over the approximately 572.46 metric tons of carbon dioxide equivalent (MT CO2e).

As GHG emissions impact from construction activities would occur over a relatively short time span, it would contribute a relatively small portion of the lifetime GHG emission impact of the proposed Project.

The total construction GHG emissions were divided by 30 to determine an annual construction emission rate to be amortized over the proposed Project’s first 30 years of operations, consistent with SCAQMD recommendations. Amortized over a 30-year period, the proposed Project is anticipated to emit approximately 19.08 metric tons of carbon dioxide per year (MT CO2e/year).

Operational Emissions
Operational emissions occur over the life of a project. The proposed Project is expected to generate GHG emissions from area, energy, and mobile-sources, in the form of vehicle trips by employees and visitors.

Area source emissions are based on the land use sizes, GHG emission factors for fuel combustion such as for landscaping equipment, and the global warming potential (GWP) values for the GHGs emitted.

Electricity usage emissions are based on the land uses, default demand factors for the land use, GHG emission factors for the utility provider, and the GWP values of the GHGs emitted. Mobile-source GHG emissions are determined based on the Project’s estimated annual vehicle miles traveled (VMT) to and from the site. Waste and water emissions are derived from the anticipated water usage and wastewater generated based on the Project’s proposed land uses and the associated water demand factors.

The estimated total net annual project emissions, including operation emissions and amortized construction and operational emissions, are detailed in Table 11, Project Greenhouse Gas Emissions.

Total GHG Emissions 67.77
Source: Impact Sciences, 2022.

As shown in Table 11, the Project’s combined long-term net operational emissions and amortized construction emissions would be approximately 67.77 MT CO2e/year. While quantified emissions are provided for informational purposes, significance under CEQA is based on the Project’s consistency with statewide and regional policies and plans to meet the state reduction goals set in SB 32, including CARB’s 2017 Scoping Plan and SCAG’s 2020 Connect SoCal RTP/SCS, see GHG Impact 2.

GHG Impact 2 Would implementation of the proposed Project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? (Less than Significant).

A proposed Project would have a significant impact with respect to GHG emissions and global climate change if it would substantially conflict with the provisions of Section 15064.4(b) of the State CEQA Guidelines.

Pursuant to Appendix G of the CEQA Guidelines, a significant GHG impact is identified if a project could conflict with applicable GHG reduction plans, policies, or regulations. The relevant adopted regulatory plans include CARB’s 2017 Scoping Plan, CALGreen, California Energy Code, SCAG’s 2020 Connect SoCal Plan, and the City’s General Plan.

Consistency with AB 32 & SB 32
The proposed Project would be consistent with applicable statewide regulatory programs designed to reduce GHG emissions consistent with AB 32 and SB 32. During construction, the Project will utilize equipment in compliance with CARB. Mobile sources during construction and operation would be subject to the requirements of California Assembly Bill 1493 (Pavley Standards), the Advanced Clean Cars Program, and the Low Carbon Fuel Standard Regulation. Additionally, the Project would be designed, constructed, and operated consistent with California Title 24 and CALGreen (2019). These regulations require projects to comply with specific standards related to building energy efficiency and green building.

3.0 Greenhouse Gas
Impact Sciences, Inc. 44 Eternal Valley Air Quality and GHG Technical Report 1366.001 March 2022
Consistency with the Final 2017 Scoping Plan Update
The Project would be consistent with CARB's Scoping Plan. The Scoping Plan (approved by CARB in 2008 and updated in 2014 and 2017) provides a framework for actions to reduce California's GHG emissions and requires CARB and other state agencies to adopt regulations and other strategies to reduce GHGs. The Scoping Plan is not directly applicable to specific projects, nor is it intended to be used for project- level evaluations. Under the Scoping Plan, however, there are several regulatory measures aimed at the identification and reduction of GHG emissions. CARB and other state agencies have adopted many of the measures identified in the Scoping Plan. Most of these measures focus on area source emissions (e.g., energy production, distribution and usage, and high-GWP GHGs in consumer products) and changes to the vehicle fleet (i.e., hybrid, electric, and more fuel-efficient vehicles) and associated fuels (e.g., Low Carbon Fuel Standard), among others. The 2008 Scoping Plan recommends strategies for implementation at the statewide level to meet the goals of AB 32 and establishes an overall framework for the measures that will be adopted to reduce California's GHG emissions. The 2017 Scoping Plan Update reflects the 2030 target of a 40% reduction below 1990 levels codified by SB 32. The Project would comply with all regulations adopted in furtherance of the Scoping Plan to the extent required by law and to the extent that they are applicable to the proposed Project.

Consistency with SCAG’s Connect SoCal Plan
At the regional level, SCAG’s Connect SoCal Regional Transportation Plan and Sustainable Communities Strategy (RTP/SCS) represent the region’s Climate Action Plan that defines strategies for reducing GHGs.

In order to assess the Project’s potential to conflict with the RTP/SCS, this section analyzes the Project’s land use profile for consistency with those in the RTP/SCS. Generally, projects are considered consistent with the provisions and general policies of applicable City and regional land use plans and regulations, such as SCAG’s RTP/SCS, if they are compatible with the general intent of the plans and would not preclude the attainment of their primary goals.

As shown in Table 13, Project Consistency with SCAG’s RTP/SCS, the Project would be consistent with the applicable strategies set forth in the RTP/SCS’s “A Path to Greater Access, Mobility, & Sustainability” chapter. Therefore, the Project would be consistent with the applicable GHG reduction related actions and strategies contained in Connect SoCal.

1.0 Introduction
The following is a Biological Assessment for the proposed Eternal Valley Cemetery Project (project) located in the Placerita Canyon area of Santa Clarita, California. This report provides an inventory of the biological resources at the site and an analysis of those impacts to biological resources potentially resulting from implementation of the proposed project. This assessment is intended to assist the City of Santa Clarita in determining potential impacts to biological resources as part of CEQA analysis.

The report first covers the literature reviewed and field survey conducted to identify the biological resources already recorded from the region of the project area, followed by a discussion of existing biological conditions including vegetation and plant communities, natural communities of special concern, observed common and special-status plant species, observed common and special-status wildlife, habitat linkages and wildlife movement. A vegetation map and representative photographs of habitat conditions at the project site are provided. This report discusses the existing biological conditions and resources within the study area that may be under the jurisdiction of the California Department of Fish and Wildlife (CDFW) or other responsible agencies. Lists of plant and wildlife species observed, as well as an assessment of the potential for occurrence of special-status plant and wildlife species at the site are provided as appendices to the report.

1.1 PROJECT DESCRIPTION
The proposed project includes an application to permit the construction of a future cemetery burial site and major grading. The Applicant intends to construct additional lawn space for cemetery burials. A proposed site plan prepared by Hunsaker & Associates dated October 14, 2020 is provided as Appendix 1.

1.2 PROJECT SITE AND STUDY AREA DESCRIPTION
The project survey area encompasses a partially graded area just west of the Eternal Valley Cemetery in Santa Clarita, California. The project site is located north of the intersection of Sierra Highway and Needham Ranch Parkway. The entire project site lies within the USGS Oat Mountain quadrangle (Figure 1). The project site is partially undeveloped with sage scrub habitat. Historical imaging shows that the site was partially graded sometime at the end of 2017 to the beginning of 2018. It is unknown if this historical grading was permitted through an additional project. The site is surrounded by commercial and residential development and marginal open space to the west. There is significant open space to the south and east of the project site. An aerial image of the study area and vicinity is provided as Figure 2. ^

2.0 Methods
A literature review was performed in preparation for a field survey that included information available in standard biological references (e.g., Baldwin et al. 2012; Sawyer, Keeler-Wolf, and Evens 2009; Reid 2006; Stebbins 2003; and Prigge and Gibson 2013), and relevant lists and databases pertaining to the status and known occurrences of sensitive and special-status resources. Other sources of information included aerial photographs, topographic maps, soil survey maps, and relevant policy and planning documents. The following sources were among those reviewed in preparation for a field survey, or that were consulted during preparation of this report (for a complete list see the references section):
• Biogeographic Information and Observation System (BIOS), California Department of Fish and Wildlife (CDFW), data as of October 11, 2020;
• California Natural Diversity Database (CNDDB) Rarefind 5 report for the 7.5’ USGS Oat Mountain quadrangle and five surrounding quadrangles, CDFW, data as of October 11, 2020;
• California Native Plant Society (CNPS) Inventory of Rare and Endangered Vascular Plants of California report for the 7.5’ USGS Oat Mountain quadrangle and five surrounding quadrangles, CNPS, data as of October 11, 2020; • FWS Critical Habitat Mapper for Threatened and Endangered Species, U.S. Fish and Wildlife Service (USFWS), data as of October 11, 2020;
• List of Special Vascular Plants, Bryophytes, and Lichens, CDFW, October 11, 2020; • List of Vegetation Alliances and Associations (Natural Communities List), CDFW, October 2020; and,
• Special Animals, CDFW, October 11, 2020.

Senior biologist Courtney McCammon conducted biological surveys on October 8, 2020 between 0753 – 1144 hours and again on October 24, 2020 between 0949 – 1202 hours. Survey conditions ranged from 63 – 68°F, cloudy to partly cloudy, and light wind. The surveys included a search for protected and regulated biological resources, including rare, threatened, and endangered plant and wildlife species, special habitats, sensitive natural communities, jurisdictional wetlands and non-wetland Waters of the U.S., jurisdictional streambed and riparian habitat, and locally sensitive resources, as well as to evaluate the importance of the site for wildlife movement. A delineation of potential jurisdictional features was not conducted. The survey extent included all areas potentially subject to any direct impacts of construction, temporary and permanent. The surveys were performed by slowly walking several transects across the site.

An inventory of vascular plants and wildlife observed was recorded during the surveys, with all species identified to the taxonomic level necessary to determine their status (Appendix 2 and Appendix 3). Vascular plant species determinations were made using The Jepson Manual:

Vascular Plants of California, 2nd edition. Plant communities were correlated with the Vegetation Classification of the Santa Monica Mountains Natural Recreation Area and Environs in Ventura and Los Angeles Counties, California (CDFW/CNPS, January 2006) and the List of Vegetation Alliances and Associations (Natural Communities List) (CDFW, September 2010). Vertebrate wildlife species observed at and in the vicinity of the site were identified by direct observation, sign (e.g., tracks, scat, or burrows), or vocalization. Several photographs were taken as a record of site conditions at the time of the survey and are provided in the photo plate below.

3.0 Environmental Setting
The study area includes a large, partially graded, multi-level site that consists of heavy nonnative plant influence. Natural vegetation, consisting primarily of coastal sage scrub occurs in the northern portion of the study area. The project is accessed from Needham Ranch Road through a paved street but appears to also be accessed from the Eternal Velley Cemetery. The work area is gently sloping. Beyond the proposed work areas, natural and invasive plant communities exist up and down the canyon with single family residential homes and commercial buildings in the immediate vicinity as well as the Eternal Valley Cemetery to the east.

The project site is situated within the inland foothills of the Angeles National Forest, at elevations ranging from approximately 1610 to 1653 feet (491 – 504 m) above mean sea level.

The site is generally dry and exposed. The average high/low summer temperatures in the lower elevation inland foothills of the Angeles National Forest are 90/50°F, average high/low winter temperatures are 68/40°F, and precipitation is approximately 18 inches per year. The soils are of the Saugus loam association, 30 to 50 percent slopes, which are comprised of weakly consolidated alluvium, well drained soils that formed in paralithic bedrock.

The project site does not appear to support any formal water features though there are some sloped canyons potentially producing canyons that could convey water in extreme weather events (refer to Figure 2).

4.0 Biological Resources

4.1 VEGETATION AND PLANT COMMUNITIES
The vegetation at the site generally consists of sage brush, ceanothus shrubland, and bare/disturbed habitats. The vegetation within the project area was correlated with the Vegetation Classification of the Santa Monica Mountains Natural Recreation Area and Environs in Ventura and Los Angeles Counties, California (CDFW/CNPS, January 2006) and the List of Vegetation Alliances and Associations (Natural Communities List) (CDFW, September 2010). These documents provide lists of plant communities occurring in Los Angeles county environs in the State of California, respectively. In each of these documents plant communities are assigned a conservation status rank (also known as “rarity rank”), which is used to determine the sensitivity of the plant community. The plant communities within the project areas are shown on Figure 3.

There are no sensitive communities within the study area.

Shrubland Communities
Artemisia californica – Salvia mellifera Shrubland Alliance This shrubland alliance occurs in the northern portion of the project site. The vegetation is thick and appears to be old-growth sage scrub habitat. Scrub species including black sage (Salix mellifera) and California sagebrush (Artemisia californica) are the primary cover in this plant community. Chaparral yucca (Hesperoyucca whipplei), Sugar bush (Rhus ovata), and bush monkeyflower (Diplacus aurantiacus) are sporadic throughout the vegetation community and present at low cover. A shrub layer of elderberry (Sambucus nigra ssp. caerulea) is present in the “bowl” area only. This vegetation alliance is within a USFWS Critical Habitat polygon for coastal California gnatcatcher (Polioptila californica californica) and was determined to be intact such that it is possible the species could use the area for foraging and nesting.

Ceanothus oliganthus Shrubland Alliance
This shrubland alliance occurs in the center of the project site on the areas immediately surrounding the dirt access road. Thick leaf yerba santa (Eriodictyon crassifolium), chamise (Adenostoma fasciculata), and hoaryleaf ceanothus (Ceanothus crassifolius) are the predominant shrub layer in this vegetation alliance. This vegetation alliance is somewhat disturbed by the use of the area as a storage yard by the project as well as the cemetery.

Other Communities
Individual Trees
Approximately two (2) “individual trees” exist within the project site but because of the severity with which they were burnt in the last fire, they are suspected to be eucalyptus trees but identification difficult due to the severity of the burns. These trees are in the northern portion of the project site in the “bowl” area.

Ruderal Vegetation
Legend
Barren or Sparsely Vegetated (Ruderal)
Areas mapped in this classification are barren or consist primarily of sparse cover of non-native ruderal species. These areas have been graded or cleared of vegetation and may be mowed or otherwise disturbed on a regular basis. Within the project area, this includes the southern portion of the project site, particularly the west facing slope adjacent to Needham Ranch Road, the areas directly adjacent to the dirt access road, the area along the eastern edge of the property adjacent to the cemetery, and the proposed fill site. Selected species observed include tocalote (Centauria melitensis), bromes, deerweed (Euphorbia maculate), and black mustard (Brassica nigra). These areas generally lack native species. These areas appear to be used as storage of construction materials as well for the current project along Needham Ranch Road and the Eternal Valley Cemetery.

4.2 PLANT INVENTORY
Appendix 2 provides a list of the common plant species observed during the site survey. The list is representative of the plants observed during the survey, which may not have been during the blooming period for some plants. The majority of the project site has been clear of vegetation and apparently graded with a culvert installed. Non-native species dominant the disturbed portion of the project site with species such as tocalote (Centauria melitensis) and black mustard (Brassica nigra). A majority of the intact native vegetation exists in the northern half of the project site supporting a sage scrub habitat primarily consisting of California sagebrush (Artemisia californica) and black sage (Salix mellifera). Additional discussion regarding specialstatus plant species and communities is provided in sections 5.1 and 5.2.

4.3 WILDLIFE INVENTORY
Appendix 3 provides a list of the common wildlife species observed during the site survey. The list is representative of only a sample of wildlife species expected to utilize the site for foraging, cover, and reproduction. Though, the list is representative of wildlife most commonly seen during daytime surveys. The project site is surrounded on the southern and western sides by open space allowing for additional species to utilize the site routinely such as raptors and some mammal species including coyote, bobcat, and mule deer. Bird species observed are common year-round residents though some likely utilize the site as nesting habitat as well. Additional discussion regarding special-status wildlife species is provided in section 5.5.

5.0 Special-Status Biological Resources
Habitat conditions observed at the study area were used to evaluate the potential for occurrence of special-status biological resources based on these searches and the professional expertise of the investigating biologist. The potential for each special-status species to occur in the study area was then evaluated according to the following criteria:
• Not expected. Habitat on and adjacent to the site is clearly unsuitable for the species requirements (foraging, breeding, cover, substrate, elevation, hydrology, plant community, site history, disturbance regime). It is very unlikely the species would occur at the site.
• Low Potential. Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the site is unsuitable or of very poor quality. The species is not likely to be found at the site. • Moderate Potential. Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the site is unsuitable. The species has a moderate probability of being found at the site. • High Potential. All of the habitat components meeting the species requirements are present and/or most of the habitat on or adjacent to the site is highly suitable. The species has a high probability of being found at the site.
• Present. Species is observed at the site or has been recently recorded (i.e. CNDDB, other reports) from the site.

The site assessment is intended to identify the presence or absence of suitable habitat for each special-status species known to occur in the vicinity in order to determine its potential to occur in the study area. The site visit does not constitute a protocol-level or focused species-specific survey. However, if a special-status species was observed during the site visit, its presence was recorded and is discussed in this Section. In cases where little information is known about species occurrences and habitat requirements, the species evaluation was based on best professional judgment of the biologist with experience working with the species and habitats.

5.1 SPECIAL-STATUS PLANT COMMUNITIES
A review of the California Department of Fish and Wildlife’s Natural Diversity Database (CNDDB) Rarefind 5 application reveals thirteen (13) Sensitive Plant Communities/Habitats have been reported by other observers in the Oat Mountain Quadrangle area, or within adjacent quadrangles. These Sensitive Plant Communities/Habitats include:
• Southern California Threespine Stickleback Stream;
• California Walnut Woodland;
• Cismontane Alkali Marsh;
• Mainland Cherry Forest;
• Riversidian Alluvial Fan Sage Scrub;
• Southern Coast Live Oak Riparian Forest;
• Southern Cottonwood Willow Riparian Forest;
• Southern Mixed Riparian Forest;
• Southern Riparian Scrub;
• Southern Sycamore Alder Riparian Woodland;
• Southern Willow Scrub;
• Valley Needlegrass Grassland; and
• Valley Oak Woodland
None of the CNDDB-listed communities are present on the site or nearby.

5.2 SPECIAL-STATUS PLANT SPECIES
The potential for special-status plant species was assessed based upon the known occurrence(s) of the species in the area as identified from CDFW, USFWS and CNPS databases, and the presence or absence of suitable habitat within the project site based on plant community mapping. Suitable habitat was defined as areas with appropriate plant communities, soils and/or topography (elevation at MSL) to support the species based on known occurrences in those habitats and/or CDFW and CNPS documented habitat descriptions for the species. The definitions of suitable habitat were then compared against the plant community mapping conducted for the project site and local knowledge. A table of sensitive plant species for which potentially suitable habitat occurs within the project site was prepared, and the potential for occurrence for each species was determined following completion of the vegetation mapping conducted during the field survey, included in Appendix 4.

Twenty-seven (27) sensitive plant species have the potential to occur in the proposed development and use areas. Fifteen (15) have a moderate or higher potential for occurrence in the project area and are discussed in detail below. The remaining species documented from within the vicinity of the study area are unlikely or have no potential to occur in the study area.

Catalina mariposa lily (Calochortus catalinae) CNPS RPR 4.2 This species has been recorded from chaparral, cismontane woodland, coastal scrub, valley and foothill grassland habitats and ranges from 15 – 700 meters in elevation. Marginal habitat exists on site and nearby and, therefore, has a moderate potential for occurrence. None was observed during site surveys.

Club-haired mariposa lily (Calochortus clavatus var. clavatus) CNPS RPR 4.3 This species occurs in chaparral, cismontane woodland, coastal scrub, valley and foothill grassland habitats and ranges from 75 – 1300 meters in elevation. Marginal habitat exists on site and nearby and, therefore, has a moderate potential for occurrence. None was observed during site surveys.

Slender mariposa lily (Calochortus clavatus var. gracilis) CNPS RPR 4.2 This species occurs in chaparral, coastal scrub, valley and foothill grassland habitat and ranges from 320 – 1000 meters in elevation. This species is known from at least nine occurrences in the Santa Clarita Valley. Only marginal habitat exists on site and nearby and much of it is disturbed so it is considered to have a moderate potential of occurrence. No slender mariposa lilies were observed during site surveys. Known from nine occurrences.

Plummer’s mariposa lily (Calochortus plummerae) CNPS RPR 4.2 This species is typically found in chaparral, cismontane woodlands, coastal scrub, lower montane coniferous forests, valley and foothill grassland habitat with granitic or rocky soils and ranges from 100 – 1700 meters in elevation but is less common in the higher elevations. Only limited suitable habitat exists on site and nearby so it has a moderate potential for occurrence. None was observed during site surveys.

Santa Susana tarplant (Deinandra minthornii) CNPS RPR 1B.2 This species is found in Chaparral and coastal scrub/ rocky habitats and ranges from 280 – 760 meters in elevation. Marginal habitat exists on site and nearby with no plants observed during site surveys.

Paniculate tarplant (Deinandra paniculata) CNPS RPR 4.2 This species prefers coastal scrub, valley and foothill grassland, and vernal pools - usually vernal mesic. Ranging from 25 – 950 meters, there is marginal habitat on site and nearby but no plants were observed during the survey.

Blochman’s dudleya (Dudleya blochmaniae ssp. blochmaniae) CNPS RPR 1B.1 This species prefers coastal bluff scrub, chaparral, coastal scrub, and valley and foothill grassland habitats ranging from 5 – 450 meters. Marginal habitat exists on site and nearby with no plants observed during site surveys.

Many-stemmed dudleya (Dudleya multicaulis) CNPS RPR 1B.1 This species can be found in chaparral, coastal scrub, and valley and foothill grassland habitats ranging from 15 – 790 meters. Marginal habitat exists on site and nearby with no plants observed during site surveys.

5.3 COUNTY PROTECTED TREES
The City of Santa Clarita defines protected trees as any oak tree of the genus Quercus, including, but not limited to, valley oak (Quercus lobata), California live oak (Quercus agrifolia), canyon oak (Quercus chrysolepis), interior live oak (Quercus wislizenii) and scrub oak (Quercus dumosa), regardless of size. No protected trees were found on the project site though they do exist nearby.

5.4 JURISDICTIONAL WATERS/HABITAT
No wetlands or jurisdictional features were identified within the property. No wetland-associated plant species were detected directly on the subject property.

5.5 SPECIAL-STATUS WILDLIFE SPECIES
For the purposes of this assessment, special-status wildlife species are those species that are listed, proposed for listing, or that meet the criteria for listing as endangered, threatened, or rare under the FESA or CESA; and those that are listed on the CDFW’s Special Animals list with a designation of SSC (California Species of Special Concern) or CFP (California Fully Protected).

A total of 91 wildlife species were included in the 9-quad CNDDB search. No species listed as Endangered, Threatened, California Fully-Protected, or as a California Species of Special Concern have been observed at the project site. However, the property and surrounding area does contain federally designated Critical Habitat for a listed wildlife species. An analysis of the potential for occurrence of special-status wildlife at the sites is presented in Appendix 5, which includes the species’ protected status, primary habitat associations, and an assessment of their potential for occurrence (high, moderate, low, or not expected). The potential for occurrence was considered through research of the CDFW Natural Diversity Database (CDFW 2020) using the Rarefind application for special-status “elements” on the Oat Mountain quadrangle and eight adjacent quadrangles. The potential for occurrence analysis provides a speculative assessment of the potential for the occurrence at the site of special-status animals on the basis of their known distribution and habitat requirements. In addition, U.S. Fish and Wildlife Service (USFWS) Birds of Conservation Concern, and CDFW special-status invertebrates are all considered special-status species.

The potential for occurrence of these special-status species on the project site was assessed based upon the known occurrence(s) of the species in the area as identified from CDFW and USFWS databases and the presence or absence of suitable habitat within the project site. Suitable habitat was defined as areas with appropriate vegetation, soils and/or topography (elevation at MSL) to support the species based on known occurrences in those habitats and/or documented occurrences of the species. A table of sensitive wildlife species for which potentially suitable habitat occurs within the project site was prepared, and the potential for occurrence for each species was determined following completion of the vegetation mapping conducted during the field survey, included in Appendix 5.

As described in Appendix 5, two (2) reptiles and eleven (11) birds have a moderate or high potential to occur on or adjacent to the site. The following special-status species have potential to occur at the site, with varying probabilities ranging from moderate to present:

San Diegan tiger whiptail (Aspidoscelis tigris stejnegeri) CDFW Species of Special Concern.

This long slender lizard is most commonly associated with open grasslands, scrublands and woodlands. Some suitable habitat is present on site, but disturbance history may preclude species from occurring in project limits.

California glossy snake (Arizona elegans occidentalis) CDFW Species of Special Concern Prefers arid scrub, rocky washes, grassland, and chaparral habitats. Some suitable habitat is present on site, but disturbance history may preclude species from occurring in project limits.

White-tailed kite (Elanus leucurus) CDFW California Fully Protected Prefers open vegetation for foraging and uses dense woodlands for cover and nesting. This species is known from and may periodically forage in the project area and the provides very limited suitable nesting for this species.

Cooper’s hawk (Accipiter cooperi) CDFW Waitlisted
This species historically prefers dense stands of live oaks and riparian woodlands but can adapt to nest in the most urban environs. It is known from the area and the oak trees on site provide some limited suitable nesting habitat.

American peregrine falcon (Falco peregrinus anatum) CDFW California Fully Protected Occurs most frequently along the coast and over other large bodies of water. Known to be a seasonal visitor to the area but the site does not provide suitable nesting for this species.

Rufous hummingbird (Selasphorus rufus) CDFW California Special Animal Prefers open areas, yards, parks, and forests up to the tree line. Some suitable foraging habitat exists on site, though not known to nest in project vicinity.

Costa’s hummingbird (Calypte costae) CDFW California Special Animal This species prefers desert scrub, chaparral, and sage scrub habitats. Some suitable foraging and nesting habitat present on site.

California gnatcatcher (Polioptila californica) CDFW Species of Special Concern, Federally Endangered
This species is strongly associated with coastal sage scrub in areas of flat or gently sloping terrain. The project site is within a USFWS Critical habitat polygon for this species and there is small but suitable sage scrub habitat on site that could be used to nest and forage.

Loggerhead shrike (Lanius ludovicianus) CDFW Species of Special Concern Prefers grasslands with scattered shrubs, trees, fences or other perches. This species is uncommon in the area, but some limited foraging and nesting habitat is present.

Southern California rufous-crowned sparrow (Aimophila ruficeps canescens) CDFW Waitlisted
This species prefers coastal sage scrub habitat. It is known from the area and some suitable foraging and nesting habitat is present on site.

Bell’s sage sparrow (Amphispiza belli belli) CDFW Waitlisted This species prefers coastal sage scrub and chamise chaparral habitat. It is known from the area and some suitable foraging and nesting habitat is present on site.

The remaining wildlife species documented from within the vicinity of the study area have low or no potential to occur in the study area.

5.6 HABITAT LINKAGES AND WILDLIFE MOVEMENT
Wildlife corridors link together areas of suitable habitat that are otherwise separated by rugged terrain, changes in vegetation, or human disturbance. The fragmentation of open space areas by urbanization creates isolated “islands” of wildlife habitat. In the absence of habitat linkages that allow movement to adjoining open space areas, various studies have concluded that some wildlife species, especially the larger and more mobile mammals, will not likely persist over time in fragmented or isolated habitat areas because they prohibit the infusion of new individuals and genetic material (MacArthur and Wilson, 1967; Soulé, 1987; Harris and Gallagher, 1989; Bennet, 1990). Corridors effectively act as links between different populations of a species.

Corridors mitigate the effects of habitat fragmentation by: (1) allowing animals to move between remaining habitats, which allows depleted populations to be replenished and promotes genetic diversity; (2) providing escape routes from fire, predators, and human disturbances, thus reducing the risk that catastrophic events (such as fires or disease) will result in population or local species extinction; and (3) serving as travel routes for individual animals as they move within their home ranges in search of food, water, mates, and other needs (Noss, 1983; Fahrig and Merriam, 1985; Simberloff and Cox, 1987).

Based on a review of the following documents the project site is not within an area that has been identified as important to wildlife movement, such as a regional-scale habitat linkage or a wildlife movement corridor:
• South Coast Missing Linkages Project: A Linkage Design for the Santa Monica Mountains-Sierra Madre Connection (Penrod, K. et. al., 2006).
• California Essential Connectivity Project: A Strategy for Conserving a Connected California (Spencer et al., February 2010).

The study area is located in an area delineated as a “Connections with Implementation Flexibility” by the California Essential Connectivity Project map. The purpose of the map is to focus attention on large areas important to maintaining ecological integrity at the broadest scale.

The map indicates that the study area is located in a low-cost area, which means it would be less permeable for wildlife to transit the site (i.e., not well suited for wildlife movement). The potential importance of the development area to wildlife movement was also evaluated both in the field and by reviewing recent aerial photographs of the site and the surrounding area.

Although the study area provides vegetative cover and native habitats suitable for the movement of a diversity of species, the proposed development will not have a negative effect on wildlife movement. There is extensive open space to the immediate east and south of the project site allowing for animals to freely move without hinderance. Gates King Open Space to the west provides some refuge for wildlife in the area as well. Major freeways (I-5 and CA-14) are immediately adjacent to the project site essentially “chopping up” the natural habitat and majoring it difficult for wildlife to move to and from the site. There is no “bottleneck” that exists on the site that would keep animals from accessing large patches of open space. The work area is situated within an area that is previously disturbed and would not convert natural habitats that would otherwise contribute to fragmentation.

5.7 SIGNIFICANT ECOLOGICAL AREAS (SEA)
These areas contain resources that are considered rare or unique, critical to the maintenance of wildlife species, are relatively undisturbed habitats, and/or serve as habitat or corridors that promote species movement. The project site is not within a Significant Ecological Area. The nearest SEA is the “Santa Clara River” at 695 meters away (~2,280 feet) and the “Santa Susana Mountains/Simi Hills” SEA at 595 meters away (~1,952 feet) from the work area (Figure 4).

5.8 USFWS CRITICAL HABITAT
The project is within USFWS Designated Critical Habitat for the coastal California gnatcatcher and the polygon encompasses the entire site (Figure 5). Suitable sage scrub habitat for the coastal California gnatcatcher exists primarily in the northern half of the project site and is approximately 3-acres in size. The vegetation is healthy enough to support foraging and nesting by coastal California gnatcatcher.

6.0 Impact Analysis
This impact analysis relies on the project description and a site plan provided by Hunsaker & Associates, dated October 14, 2020, which is attached as Appendix 1. The proposed project is for the construction of an additional lawn burial area for the existing Eternal Valley Cemetery.

No structures, additional landscaping, nor drainage structures are being proposed as a part of this project.

6.1 IMPACTS TO SPECIAL-STATUS PLANT SPECIES
This evaluation of impacts to special-status plants considers those species that require mandatory special consideration and/or protection pursuant to the Federal Endangered Species Act, the State Endangered Species Act, and/or CEQA. The site has the potential to support fifteen special status plant species though none were observed on site during the survey therefore the impacts are expected to be less than significant.

6.2 IMPACTS TO SENSITIVE PLANT COMMUNITIES
No sensitive plant communities exist on the project site therefore the impacts are expected to be less than significant.

6.3 IMPACTS TO SPECIAL-STATUS WILDLIFE SPECIES
No rare, threatened, or endangered wildlife species have been observed within the study area. As described in Section 5.5 and Appendix 5, thirteen special status species have potential to forage over or to occur within the project footprint, if only temporarily, including but not limited to white-tailed kite, American peregrine falcon, San Diegan tiger whiptail, and California glossy snake. To ensure disturbance does not occur to any special status species and reduce impacts to less than significant, MM BIO-1 should be implemented.

The site has been identified by the USFWS as Designated Critical Habitat for the coastal California gnatcatcher and the biologist noted suitable habitat in the northern portion. Protocollevel focused surveys were initiated on October 28, 2020 and will be completed by a qualified biologist prior to any construction occurring on the project site to ensure no coastal California gnatcatchers exist on the project site and there are no impacts to the species. A formal report will be sent to the appropriate agencies following completion of the surveys.

6.4 IMPACTS TO NESTING BIRDS
Should there be any vegetation disturbing activities during the nesting bird season, there could be potential to result in removal or disturbance to trees or shrubs that could contain active bird nests. Birds nesting in the vicinity of project activities may potentially be disturbed by noise, lighting, dust, and human activities associated with the project, which could result in nesting failure and the loss of eggs or nestlings. Implementation of MM BIO-2 would reduce significant impacts to less than significant.

6.5 IMPACTS TO WILDLIFE MOVEMENT
The proposed project would not affect wildlife connectivity, nor would it fragment natural habitats. The proposed areas of development are already partially disturbed. There is extensive open space to the east and south of the project site providing suitable habitat for local wildlife and better opportunities for wildlife movement throughout the area. Therefore, impacts to wildlife movement would be less that significant.

6.6 IMPACTS TO JURISDICTIONAL HABITAT
No sensitive plant community exists on the project site therefore the impacts are expected to be less than significant.

6.7 IMPACTS TO SEA
The proposed project would not affect any mapped Significant Ecological Areas as none are present on site and are far enough away that the impact is less than significant.

6.8 IMPACTS TO USFWS CRITICAL HABITAT
A majority of the proposed project is mapped as USFWS Critical Habitat for the coastal California gnatcatcher. However, in the proposed project site, only the northern-most portion is considered suitable habitat for gnatcatcher. The proposed project would result in impacts to USFWS Critical Habitat but implementation of MM BIO-3 and MM BIO-4 would reduce impacts to less than significant.

7.0 Mitigation Measures
Potentially significant impacts as a result of the proposed project would be reduced to a less than significant level through implementation of the following mitigation measures.

MM BIO-1 Biological Monitor. A biological monitor, approved by the City and CDFW, shall be present on site for the duration of the project. The biological monitor shall ensure compliance of all permit regulations as required by each agency. These include but are not limited to surveying the work area each morning prior to disturbance to ensure no special-status wildlife are present. In the event special status species are being disturbed, the Biological Monitor shall have the authority to stop work and the Biologist, City representative(s) and CDFW will confer to determine what, if any, additional action should be taken to minimize disturbance.

MM BIO-2 Nesting Bird Surveys. To the extent feasible construction activities should be timed to avoid the nesting/breeding season (February 1 through August 31). If the construction activities cannot avoid starting work within the nesting season, no earlier than 14 days prior to ground or vegetation disturbing activities, a qualified biologist shall perform a field survey to determine if active nests of any bird species protected by the state or federal Endangered Species Acts, Migratory Bird Treaty Act, and/or the California Fish and Game Code Sections 3503, 3503.5, or 3511 are present in the disturbance zone or within 100 feet of the disturbance zone for songbirds or within 500 feet of the disturbance zone for raptors and special-status bird species. A second nesting bird survey shall be conducted within three (3) days of the start of ground or vegetation disturbing activities. A letter report summarizing the methods and results of the surveys shall be submitted to the County prior to commencement of project activities. During the nesting season, if active nests are identified during pre-construction surveys or discovered after construction has started, they will be protected with spatial buffers. The buffer will be determined on a case-by-case basis by a qualified biologist. If a state or federally protected species are involved, the biologist shall coordinate with the CDFW and/or USFWS to determine an appropriate buffer or need for a take permit. The size of the buffer will be determined based on-site conditions, the species’ life history and disturbance tolerance, the nest’s distance to construction activities, and the type of construction ongoing in the vicinity of the nest. Buffers will be clearly delineated (e.g., using rope, flagging, signage); or may be defined by natural or manmade features that are deemed sufficient to prohibit access (e.g., tree rows, fences). Buffers will remain in place and will be monitored and maintained regularly during the nesting season or until the biological monitor determines that the young have fledged, or the nest failed.

Construction personnel shall be instructed on the sensitivity of the area. Upon completion of the nesting bird surveys and any nest monitoring, a letter report shall be prepared and submitted to the City of Santa Clarita documenting compliance with this measure.

MM BIO-3 Mitigation of Critical Habitat. The approximate 3 acres of USFWS Critical Habitat for coastal California gnatcatcher shall be mitigated at a ratio acceptable to the appropriate agencies. The site of the mitigation will be chosen with assistance from the appropriate agencies. A restoration plan shall be written by a qualified biologist and submitted to the agencies for approval.

MM BIO-4 Marking of work area. Prior to construction activities, the designated work areas will be clearly marked, and no vegetation shall be removed outside of this marked area. Project personnel should stay within the designated work areas to the extent feasible. Work areas shall be marked for the entire duration of the project. Silt fencing shall be installed to ensure that no debris or dirt enters areas outside of the project area.
