DENSITY BONUS HOUSING AGREEMENT
Maison’s Palmdale Blvd 150, LLC
Agreement No. A-8767
THIS DENSITY BONUS HOUSING AGREEMENT ( this “Agreement”), dated as of ___________ ____, 2024, is entered into by and between the City of Palmdale, a municipal corporation of the State of California (the “City”), and Maison’s Palmdale Blvd 150, LLC , a Delaware limited liability company and/or its assigns (the “Owner”), as follows:
RECITALS
A. The Owner is the owner of a fee interest in certain real property located in the City of Palmdale, County of Los Angeles, State of California, identified as APN 3023-002-184, located at the Southeast corner of East Palmdale Boulevard and Hudsonia Street and legally described in Exhibit “A” attached hereto and incorporated by reference (the “Property”).
B. The Owner will construct a 191-unit affordable housing development, 64 three- and four-bedroom single family homes, 64 one -bedroom junior accessory dwelling units, 48 two- bedroom accessory dwelling units (“ADUs”), 15 three -bedroom ADUs, and associated landscaping and parking (“Residential Development” of “Project”).
C. The Owner proposes construction of a rental housing development of 189 units for low-income individuals and families and two manager’s unit. At least ten percent (10%) of the units that count towards the Project’s base density as defined pursuant to Government Code section 65915 (64 units) will be available to and occupied by households whose incomes do not exceed the maximum income of low -income households in Los Angeles County as determined by the California Department of Housing and Community Development.
Density Bonus Housing Agreement Agreement No. A-8767

APN: 3023-002-184
D. Under California Government Code Section 65915, et seq. and Palmdale Municipal Code Section 17.25.020, the City must, upon the request of an applicant, grant a density bonus and/or certain incentives/concessions and/or waivers/modifications for any development applicant that seeks and agrees to construct a minimum number of housing units that are affordable to low or very low-income households (the “Density Bonus Law”).
E. The subject site has a General Plan Land Use Designation of Single Family Residential 3 (up to 6 dwelling units per acre) and is zoned Single Family Residential 3 (up to 6 dwelling units per acre). The Density Bonus Law requires that, when an applicant includes at least 10% low-income units, the City must grant a 20 % density bonus over the base density, which would allow an additional 4 units per acre in the Residential Development. Because ADUs do not count towards density, the Project does not require a density bonus . To provide for affordable housing cost of the low-income units and fit the Project on the Property as designed, the Owner has requested a cost -saving concession and a waiver in accordance with California Government Code Section 65915, et seq. and Palmdale Municipal Code Section 17.25.020, as follows:
a. A concession pursuant to Palmdale Municipal Code Section 17.37.010.D.7, to allow composite shingles for the roofing material.
F. The Owner has also requested one waiver to development standards that, if applied, would have the effect of physically precluding the construction of the Project in accordance with California Government Code Section 65915, subdivision (e)(1), as follows:
a. A waiver to the minimum garage length in Palmdale Municipal Code Section 17.37.010.C.3.b to allow a minimum garage length of 20 feet.
G. The City and the Owner enter into this Agreement purs uant to and in accordance with California Government Code Section 65915, et seq., and Section 17.25.020 of the Palmdale Municipal Code, in order to provide housing for lower income households.
H. The City finds that granting the concession and waiver listed under Recital E and F, above, will result in actual and identifiable cost reductions to provide for affordable housing cost, will not have an adverse impact upon public health and safety, the physical environment, or any property that is listed in the California Register of Historical Resources, and is consistent with state and federal law. The City also finds that the Residential Development is consistent with the General Plan.
NOW, THEREFORE, in consideration of the mutual covenants and provisions contained herein, the parties hereto agree as follows:

PROJECT DESCRIPTION
The applicant is requesting approval of a Density Bonus Agreement and Tentative Tract Map application to subdivide a 20-acre parcel into 66 parcels to facilitate the future construction of approximately 190 dwelling units comprised of a detached single-family dwelling unit, an accessory dwelling unit, and a junior accessory dwelling unit on the 64 lots dedicated for residential uses. The two remaining parcels will be used for a drainage basin and a parcel dedicated to a shared common area for recreation purposes.
Ten percent of the units will be available to households with incomes that do not exceed the maximum income of low-income households in Los Angeles County as determined by the California Department of Housing and Community Development. The request includes two concessions from the development standards as allowed by the State Density Bonus Law (California Government Code Section 65915) The Palmdale Municipal Code (PMC) requires a Density Bonus Agreement and Tentative Map application approval for the proposed project. A Subdivision Development Plan will be required for the approval of the proposed design and individual plot plans for the comprehensive development.
Density Bonus
A density bonus is an increase in the overall number of housing units that a developer may build on a site in exchange for providing affordable housing. State Density Bonus Law, pursuant to Section 65915 of the California Government Code, offers incentives that are intended to encourage the development of affordable housing, including up to an 80 percent increase in density.
The project site has a General Plan Land Use designation and zone of Single-Family Residential 3 (SFR 3, 7,000 square foot lots; up to 6 dwelling units per acre). The project site is approximately 20 acres and the maximum density is 120 detached single-family residential units. Density Bonus Law requires that, when 10 percent of all units are for low-income households, the City must grant an 20 percent density bonus over the base density, which would allow an additional 4 units for this development. Although the maximum density for the project site is 120 units, the residential development does not require an increased density and the applicant proposes to construct a total of 64 detached single-family residential units and 127 ADU’s and JADU’s for a total of 191 residential units.
Under California Fair Housing Laws, the proposed ADUs and JADUs are not subject to a jurisdiction's density requirements.

AGR 24-0002 and TTM 83359
March 14, 2024
Of the 191 units proposed, 10 percent of the units are required to be reserved for low- income households. Additionally, the owner has requested cost-saving concessions in accordance with Government Code Section 65915, et seq. and PMC Section 17.25.020 (Density Bonus Agreements), as follows:
1. To allow composite shingles for roofing material.
2. To allow a reduction of the required garage width of 20 feet.
The Housing Division has determined that granting the concessions listed above will result in actual and identifiable cost reductions to provide affordable housing. In addition, the proposed project will contribute to the City’s Regional Housing Needs Assessment (RHNA) allocation.

Access
Street improvements will be constructed to provide internal circulation as well as connections to existing roads Bell Avenue, Hudsonia Street, Rainer Avenue, Keston Drive, and Oak Street. No streets or driveways proposed by the project will open directly onto Palmdale Boulevard from the project site. The City Engineer and Los Angeles County Fire Department have reviewed the project and determined that it is designed with adequate access to accommodate safe vehicular flow. Furthermore, access to the site will not be affected by the phasing of the development.
ENVIRONMENTAL REVIEW
Pursuant to the California Environmental Quality Act (CEQA), an Initial Study, to determine whether the project would have a significant effect on the environment, has been prepared. The Initial Study analyzed the potential for environmental impacts and all topics were found to have either no impact, a less than significant impact, or a less than significant impact with mitigation incorporated. Mitigation measures for biological resources, cultural resources, geology/soils, and greenhouse gas emissions were included to reduce impacts to a less significant level. In addition, the western Joshua tree has been designated a protected species under the California Endangered Species Act.
Therefore, any removal of western Joshua trees on site must comply with all requirements from CDFW. The applicant must apply for an Incidental Take Permit in accordance with CDFW guidelines to address changes in State regulations relating to western Joshua trees. As such, an MND and MMRP were prepared and circulated in accordance with CEQA Guidelines.

RECITALS
A. The Owner is the owner of a fee interest in certain real property located in the City of Palmdale, County of Los Angeles, State of California, identified as APN 3023-002-184, located at the Southeast corner of East Palmdale Boulevard and Hudsonia Street and legally described in Exhibit “A” attached hereto and incorporated by reference (the “Property”).

APN: 3023-002-184
D. Under California Government Code Section 65915, et seq. and Palmdale Municipal Code Section 17.25.020, the City must, upon the request of an applicant, grant a density bonus and/or certain incentives/concessions and/or waivers/modifications for any development applicant that seeks and agrees to construct a minimum number of housing units that are affordable to low or very low income households (the “Density Bonus Law”).
E. The subject site has a General Plan Land Use Designation of Single Family Residential 3 (up to 6 dwelling units per acre) and is zoned Single Family Residential 3 (up to 6 dwelling units per acre). The Density Bonus Law requires that, when an applicant includes at least 10% low-income units, the City must grant a 20% density bonus over the base density, which would allow an additional 4 units per acre in the Residential Development. Therefore, the Density Bonus Law requires the City to permit the Residential Development’s proposed density of 10 dwelling units per acre. Additionally, in order to provide for affordable housing cost of the low- income units, the Owner has requested cost-saving concessions in accordance with California Government Code Section 65915, et seq. and Palmdale Municipal Code Section 17.25.020, as follows:
a. A concession pursuant to Palmdale Municipal Code Section 17.37.010.D.7, to allow composite shingles for the roofing material.
F. Owner has also requested one waiver to development standards that, if applied, would have the effect of physically precluding the construction of the Project in accordance with Government Code Section 65915, subdivision (e)(1), as follows:
a. A waiver to the minimum garage depth in Palmdale Municipal Code Section 17.37.101.C.3.b to allow a minimum garage depth of 20 feet.
G. The City and the Owner enter into this Agreement pursuant to and in accordance with California Government Code Section 65915, et seq., and Section 17.25.020 of the Palmdale Municipal Code, in order to provide housing for lower income households.
H. The City finds that granting the concessions and waivers listed under Recital E and F, above, will result in actual and identifiable cost reductions to provide for affordable housing cost, will not have an adverse impact upon public health and safety, the physical environment, or any property that is listed in the California Register of Historical Resources, and is consistent with state and federal law. The City also finds that the Residential Development is consistent with the General Plan.
NOW, THEREFORE, in consideration of the mutual covenants and provisions contained herein, the parties hereto agree as follows:

A scenic vista is defined as a public viewpoint that provides expansive views of a highly valued landscape for the benefit of the general public. Public views are those that are experienced from a publicly accessible vantage point, such as a roadway or public park. The California Department of dƌĂŶƐƉŽƌƚĂƚŝŽŶ;ĂůƚƌĂŶƐͿŵĂŶĂŐĞƐƚŚĞĂůŝĨŽƌŶŝĂ^ƚĂƚĞ^ĐĞŶŝĐ,ŝŐŚǁĂLJWƌŽŐƌĂŵ͕ǁŚŝĐŚĚĞƐŝŐŶĂƚĞƐ State scenic highways. A scenic highway becomes officially designated when the local governing body applies to and is approved by Caltrans for scenic highway designation and adopts a Corridor Protection Program that preserves the scenic quality of the land that is visible from the highway right of ǁĂLJ;Caltrans 2022Ϳ.
The City of Palmdale Planning Area encompasses approximately 174 square miles within a transitional area between the foothills of the San Gabriel and Sierra Pelona Mountains and the DŽũĂǀĞĞƐĞƌƚƚŽƚŚĞŶŽƌƚŚĂŶĚĞĂƐƚ;ŝƚLJŽĨPalmdale 2022aͿ. Across the Antelope Valley, elevations range from 500 to 900 feet. The high desert lies on the north side of the San Gabriel Mountains with elevations ranging between 2,500 and 3,000 feet. The project site is in a highly urbanized area that includes residential uses.

Tentative Tract Map 83359
12 a. Would the project have a substantial adverse effect on a scenic vista? A scenic vista is usually defined as a panoramic view from an elevated position or a long-range view from a public vantage point. While the City of Palmdale General Plan does not identify any specific scenic vistas in the city, General Plan Policy Land Use and Community DĞƐŝŐŶ;LUDͿ 5.7 aims for the protection and enhancement of the city’s scenic vistas and limit development in areas with high scenic value ;City of Palmdale 2022aͿ͘In addition, the proposed project does not occur along a view corridor identified in the City’s General Plan. Long range views of hillsides surrounding Antelope Valley, such as those near Angeles National Forest, are visible from the project site. PMC Section 17.36.010 ;Development Standards – Residential ZonesͿrequires that buildings within an area zoned SFR 3 shall not exceed two stories or 35 feet in height, except when permitted by a conditional use permit. Given the distance between the surrounding hillsides and the project site, and that the proposed residences would not exceed two stories in height, the project would not result in impacts to the scenic quality of hillsides in the city. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project substantially damage scenic resources, including but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? The nearest designated State ƐĐĞŶŝĐŚŝŐŚǁĂLJŝƐ^ƚĂƚĞZŽƵƚĞϮ;^Z-ϮͿůŽĐĂƚĞĚŽǀĞƌϭϲŵŝůĞƐƐŽƵƚŚŽĨ ƚŚĞƉƌŽũĞĐƚƐŝƚĞ;ĂůƚƌĂŶƐϮϬϭϵͿ͘dŚĞŶĞĂƌĞƐƚĞůŝŐŝďůĞƐƚĂƚĞƐĐĞŶŝĐŚŝŐŚǁĂLJŝƐ^ƚĂƚĞZŽƵƚĞϱϴ;^ZϱϴͿ located approximately 30 miles north of the project site. Therefore, no officially designated or eligible State scenic highways are near the project site, and the project site does not contain any trees, rock outcroppings, or historic buildings that would be impacted by the proposed project.
Therefore, impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
c. Would the project, 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 a publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?
The General Plan land use designation of the project site is Single Family Residential ;SFR 3Ϳ consistent with the SFR 3 zone in the zoning code. Land uses surrounding the project site are similarly zoned as SFR 3. Residences surround the project site to the west, south, and east. Land to the north of the project site is designated as Other Jurisdiction. Thus, the proposed project would be consistent with the current zoning and land uses within the area.
Construction of the proposed project would replace the vacant parcel and utilize building materials that would complement the aesthetics of the existing residences surrounding the site to the west, south, and east. Additionally, the proposed project would comply with PMC Section 17.36.010 ;Development Standards – Residential ZonesͿ and Section 17.86.010 ;Landscaping RequirementsͿ, which defines the requirements for building design and landscaping on the project site. Compliance with the applicable requirements would maximize the aesthetic quality of the proposed project.
While the proposed project would result in visual impacts during construction due to the presence of equipment, vehicles, construction fencing, signage, and lighting, these impacts would be temporary and limited to the construction phase only. Once fully built, the proposed project would result in the permanent impact to the visual character of the project area with the presence of Environmental Checklist

single-story, single-family homes. As discussed above, the height of the proposed development would be within the height restrictions defined by the PMC Section 17.36.010 ;Development Standards – Residential ZonesͿ. In addition, the proposed project would include construction best ŵĂŶĂŐĞŵĞŶƚƉƌĂĐƚŝĐĞƐ;DWƐͿŝŶĐůƵĚŝŶŐďƵƚŶŽƚůŝŵŝƚĞĚƚŽƉƌŽƉĞƌƐƚŽƌĂŐĞŽĨĞƋƵŝƉŵĞŶƚ͕ƉƌŽũĞĐƚƐŝƚĞ maintenance, dust control measures, and limiting hours of construction within the hours mandated by PMC Section 8.28.030 ;Construction Noise Prohibited in Residential ZonesͿ. Permanent impacts would include the presence of new development on a currently vacant site. The proposed project is located in an urbanized area and the surroundings are fully developed with residential buildings.
In addition, the Land Use and Community Design Element of the City General Plan includes policies regarding the maintenance of community design and character. Some of those policies include, but are not limited to, the following ;ŝƚLJŽĨWĂůŵĚĂůĞ2022aͿ͗ Goal LUD-4: High-quality architecture and site design in the renovation and construction of all buildings.
Policy LUD-4.5: Use visual and physical design cues within the design of a building and within building entries to emphasize the building entrance and connections to public spaces and public pathways/networks.
Policy LUD-4.7: Allow iconic and memorable building designs, particularly on larger nonresidential properties.
Policy LUD-4.8: Design sites and buildings adjacent to natural areas with transparent design elements. Employ bird-safe design near habitat areas or migratory routes.
Goal LUD-6: Pedestrian-oriented, human-scale and well-landscaped streets and civic spaces.
Policy LUD-6.3: For construction of new small-scale housing and minor subdivision projects, design site plans that provide amenities and integrated networks for walking and bicycling.
Policy LUD-6.4: Improve existing parks and public spaces throughout the city to provide beautiful, comfortable, and inviting gathering spaces.
The proposed project complies with Policy LUD-6.3 by ensuring that the streets constructed within the project site would link the community to East Palmdale Boulevard to the north as well as the existing residential projects to both the east and west of the project. In addition, the project would maintain the community’s aesthetic by following the design standards outlined in PMC Section 17.36.010 ;Development Standards – Residential ZonesͿ. The project would contain single- family residences, similar to areas surrounding the project site. Thus, the proposed project would be compatible with the surrounding neighborhoods and consistent with land uses in the area.
In
addition, the proposed project would be consistent with the General Plan and building heights would be compatible with heights allowed in the surrounding area. Therefore, implementation of the proposed project would result in a less-than-significant impact associated with visual character and scenic quality.

14 d. Would the project create a new source of substantial light or glare that would adversely affect daytime or nighttime views in the area?
The proposed project would add temporary and permanent lighting to the project area. During construction, the project would include temporary construction lighting for areas requiring additional lighting. The project would limit construction hours within the PMC Section 8.28.030 ;ŽŶƐƚƌƵĐƚŝŽŶEŽŝƐĞWƌŽŚŝďŝƚĞĚŝŶZĞƐŝĚĞŶƚŝĂůŽŶĞƐͿ requirement where construction activities are prohibited between 8:00 p.m. to 6:30 a.m. Other additional lighting sources would come from vehicles and other large operating equipment. Once operational, permanent lighting sources would primarily be from outdoor lighting necessary to ensure safety and additional vehicle lights.
Lighting associated with the proposed project would be required to comply with PMC Section 17.86.030 ;Outdoor LightingͿ, which requires consistent illumination levels with the character and use surrounding of the surrounding development; excessive illumination is prohibited. Additionally, exterior lighting would be required to be located and designed to minimize glare beyond the proposed project site. Glare onto the adjacent properties would be minimized using down casting, cut-off type fixtures, as necessary, that are shielded and would direct lights towards the specific areas needing illumination. For areas that are located near residents, the lowest allowable lighting levels would be used.
Compliance with the PMC would help to mitigate the effects of permanent light and glare induced by the proposed project. Therefore, implementation of the proposed project would result in a less than significant impact.

In addition to the federal criteria pollutants, the CAAQS also specify standards for visibility-reducing particles, sulfates, hydrogen sulfide, and vinyl chloride. Like the federal CAA, the CCAA classifies specific geographic areas as either “attainment” or “nonattainment” areas for each pollutant, based on the comparison of measured data within the CAAQS.
California is divided geographically into 15 air basins for managing the air resources of the State on a regional basis. Areas within each air basin are considered to share the same air masses and, therefore, are expected to have similar ambient air quality. If an air basin is not in either federal or State attainment for a criteria pollutant, the basin is classified as a nonattainment area for that pollutant. Under the CAA, once a nonattainment area has achieved the air quality standards for a criteria pollutant, it may be re-designated to an attainment area for that pollutant.

TACs may result in long-term health effects such as cancer, birth defects, neurological damage, asthma, or genetic damage, or short-term acute effects such as eye watering, respiratory irritation, runny nose, throat pain, and headaches. TACs are considered either carcinogenic or non-carcinogenic based on the nature of the health effects associated with exposure. For carcinogenic TACs, potential health impacts are evaluated in terms of overall relative risk expressed as excess cancer cases per one million exposed individuals. Non-carcinogenic 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.
TACs include both organic and inorganic chemical substances.

The SIP is established by incorporating measures established during the preparation of air quality attainment plans and adopted rules and regulations by each local air district, which are submitted for approval to CARB and the USEPA. The goal of an air quality attainment plan is to reduce pollutant concentrations below the NAAQS through the implementation of air pollutant emissions controls. Local air districts and other agencies, such as the Department of Pesticide Regulation and the Bureau of Automotive Repair, prepare SIP elements and submit them to CARB for review and approval. CARB then forwards SIP revisions to the USEPA for approval and publication in the Federal Register. All of the items included in the California SIP are listed in the Code of FĞĚĞƌĂůZĞŐƵůĂƚŝŽŶƐ;&ZͿĂƚϰϬ CFR 52.220.

Because ozone requires sunlight to form, it usually occurs in substantial concentrations between the months of April and October.
Ozone is a pungent, colorless, toxic gas with direct health effects on humans including respiratory and eye irritation and possible changes in lung functions. Groups most sensitive to ozone include children, the elderly, people with respiratory disorders, and people who exercise strenuously outdoors.
Carbon Monoxide
CO is a local pollutant produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood. The primary source of CO, a colorless, odorless, poisonous gas, is automobile traffic. Therefore, elevated concentrations are usually found near areas of high traffic volumes. The health effects from CO are related to its affinity for hemoglobin in the blood. At high concentrations, CO reduces the amount of oxygen in the blood, causing heart difficulty in people with chronic diseases, reduced lung capacity, and impaired mental abilities.
Sulfur Dioxide
SO
2 is a combustion product, with the primary source being power plants and heavy industries that use coal or oil as fuel. SO2 is also a product of diesel engine combustion. The health effects of SO2 include lung disease and breathing problems for people with asthma. SO2 in the atmosphere contributes to the formation of acid rain.
Nitrogen Dioxide
NO2 is a byproduct of fuel combustion, with the primary sources being motor vehicles and industrial boilers and furnaces. The principal form of NO2 ƉƌŽĚƵĐĞĚďLJĐŽŵďƵƐƚŝŽŶŝƐŶŝƚƌŝĐŽdžŝĚĞ;EKͿ͕ďƵƚEK reacts rapidly to form NO2, creating the mixture of NO and NO2 commonly called NOX. NO2 is an acute irritant.

It can also contribute to the formation of ozone/smog and acid rain.
Particulate Matter
Suspended atmospheric PM10 and PM2.5 are comprised of finely divided solids and liquids such as dust, soot, aerosols, fumes, and mists. The characteristics, sources, and potential health effects associated with PM10 and PM2.5 can be different. Major man-made sources of PM10 are agricultural operations, industrial processes, combustion of fossil fuels, construction, demolition operations, and entrainment of road dust into the atmosphere. Natural sources include windblown dust, wildfire

smoke, and sea spray salt. The finer PM2.5 particulates are generally associated with combustion processes as well as formation in the atmosphere as a secondary pollutant through chemical reactions. PM
2.5 is more likely to penetrate deeply into the lungs and poses a serious health threat to all groups, but particularly to the elderly, children, and those with respiratory problems. More than half of the PM2.5 that is inhaled into the lungs remains there, which can cause permanent lung damage. These materials can damage health by interfering with the body’s mechanisms for clearing the respiratory tract or by acting as carriers of an absorbed toxic substance.
Current Air Quality
CARB operates a network of air quality monitoring stations throughout the MDAB. The purpose of the monitoring stations is to measure ambient concentrations of pollutants and determine whether ambient air quality meets the California and federal standards. The monitoring station located closest to the project site is the Lancaster – 43301 Division Street station located approximately eight miles northwest of the project site. This monitoring station measures ozone, NO 2, PM10, and
PM2.5.
Table 3 reports ambient air quality measurements and indicates the number of days that each standard has been exceeded at the Lancaster – 43301 Division Street station. The ambient air quality in the area exceeded the State and Federal 8-hour ozone standard and the Federal PM10 standard in 2020, 2021, and 2022. The area also exceeded the State 1-hour ozone standard in 2020 and 2022 and the Federal PM
10 and PM2.5 standards in 2020 and 2021. The area did not exceed other air quality standards in 2020, 2021, or 2022.

24 Sensitive Receptors
The term “sensitive receptor” refers to a person in the population who is more susceptible to health effects due to exposure to an air contaminant than the population at large or to a land use that may reasonably be associated with such a person. Examples include residences, schools, playgrounds, childcare centers, churches, athletic facilities, retirement homes, and long-term health care facilities. Sensitive receptors that may be affected by air quality impacts associated with construction and operation of the proposed project include the residents of the single-family developments located adjacent to the western, southern, and eastern project boundaries. There are no other sensitive receptor groups within 1,000 feet of the project site.

The analysis assessed maximum daily emissions from individual construction activities, including site preparation, grading, building construction, paving, and architectural coating. Construction would require heavy equipment during demolition, site preparation, grading, building construction, and paving. Construction equipment estimates are based on surveys of construction projects within California conducted by members of CAPCOA. Note that there would be no demolition phase since the existing site is vacant.
Construction emissions were modeled in CalEEMod to occur over 18 months, starting in January 2024 with completion anticipated in July 2025. Although construction would likely begin in summer of 2024, this analysis conservatively assumes an earlier start date, as emissions factors for construction equipment are lower in later years. Construction emissions associated with development of the proposed project were quantified using the types and quantities of equipment for each construction phase as provided by the applicant. CalEEMod also estimates off-site emissions from worker, vendor, and hauling truck trips. The number of worker and vendor trips are based on CalEEMod defaults. Cut material would be used for construction of the proposed drainage basin; therefore, the project would not require material export or import.

Operational Emissions
In CalEEMod, operational sources of criteria pollutant emissions include area, energy, and mobile sources. The project’s single-family, ADU, and junior ADU uses were combined and attributed to the “Single Family Housing” land use subtype, while the proposed community amenities were modeled as a 2,630-square foot “Racquet Club.” Uncovered parking spaces and internal roadways were modeled as “Parking Lot.” The modeling analyzed 191 total dwelling units.
The proposed project would not include natural gas connections, and such emissions are therefore excluded from this analysis. Emissions associated with area sources, including consumer products, landscape maintenance, and architectural coating were calculated in CalEEMod, and standard emission rates were utilized from CARB, USEPA, and emission factor values provided by the local air ĚŝƐƚƌŝĐƚ;WK 2022Ϳ͘Mobile emissions are estimated by multiplying the project trip rate, average trip length, and the vehicle emission factors.

Significance Thresholds
To determine whether a project would result in a significant impact to air quality, Appendix G of the CEQA Guidelines requires consideration of whether a project would:
Conflict with or obstruct implementation of the applicable air quality plan; Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state ambient air quality standard;
Expose sensitive receptors to substantial pollutant concentrations; or ZĞƐƵůƚŝŶŽƚŚĞƌĞŵŝƐƐŝŽŶƐ;ƐƵĐŚĂƐƚŚŽƐĞůĞĂĚŝŶŐƚŽŽĚŽƌƐͿĂĚǀĞƌƐĞůLJĂĨĨĞĐƚŝŶŐĂƐƵďƐƚĂŶƚŝĂů number of people.
The AVAQMD has adopted numerical significant emissions thresholds to determine whether an air pollution source could contribute individually or cumulatively to the worsening local or regional air quality. These thresholds, which would apply to temporary construction and long-term operational emission, are shown in Table 4.

Forecasts used in the 2023 Ozone Plan are developed by SCAG, which are based on local general plans and other related documents that are used to develop population, employment, and traffic projections. Consistency with the 2023 Ozone Plan is determined by analyzing a project with the assumptions in the Plan. As such, projects that propose development that is consistent with the growth anticipated by the local land use plan would be consistent with the SCAG growth projections and the 2023 Ozone Plan emissions estimates.
The project involves the construction of 191 residential units that would result in an increase in the city’s population. Based on an average household size of 3.4 persons per dwelling unit in the city, the project would house approximately 649 ƌĞƐŝĚĞŶƚƐ;ĂůŝĨŽƌŶŝĂĞƉĂƌƚŵĞŶƚŽĨ&ŝŶĂŶĐĞ2023Ϳ.

The project's buildout would not exceed the 2023 Ozone Plan population growth forecast for Palmdale. The project's population growth represents approximately 1.3 percent of the total population growth expected in Palmdale between 2016 and 2045. Therefore, the proposed project would be consistent with AQMP growth assumptions and accommodated within and consistent with the 2023 Ozone Plan, and impacts would be less than significant.

b. Would the project 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?
Table 5 and Table 6 summarize maximum daily and annual emissions of pollutants throughout the construction period of the project, respectively. Detailed modeling results are provided in Appendix A. Emissions would not exceed AVAQMD significance thresholds during project construction.
Therefore, project construction would not result in a cumulatively considerable net increase of a criteria pollutant, and impacts would be less than significant.

c. Would the project expose sensitive receptors to substantial pollutant concentrations? Toxic Air Contaminants
CONSTRUCTION
Construction-related activities would result in short-term, project-generated emissions of DPM exhaust emissions from off-road, heavy-duty diesel equipment for site preparation grading, building construction, and other construction activities. DPM was identified as a TAC by CARB in 1998. The ƉŽƚĞŶƚŝĂůĐĂŶĐĞƌƌŝƐŬĨƌŽŵƚŚĞŝŶŚĂůĂƚŝŽŶŽĨWD;ĚŝƐĐƵƐƐĞĚŝŶƚŚĞĨŽůůŽǁŝŶŐƉĂƌĂŐƌĂƉŚƐͿŽƵƚǁĞŝŐŚƐ the potential non-ĐĂŶĐĞƌŚĞĂůƚŚŝŵƉĂĐƚƐ;Z ϮϬϮϭďͿ͘

which the receptors are exposed is the primary factor used to determine health risk. Dose is a function of the concentration of a substance or substances in the environment and the extent of exposure that a person has with the substance. Dose is positively correlated with time, meaning that a longer exposure period would result in a higher exposure level for the Maximally Exposed Individual. The risks estimated for a Maximally Exposed Individual are higher if a fixed exposure occurs over a longer period of time. According to the Office of Environmental Health Hazard ƐƐĞƐƐŵĞŶƚ;K

The maximum PM
2.5 emissions, which is used to represent DPM emissions for this analysis, would occur during site preparation and grading activities. While site preparation and grading emissions represent the worst-case condition, such activities would occur for three months, less than 3 percent for a 9-year health risk calculation period and less than one percent for a 30-year and 70- year health risk calculation period. PM2.5 emissions would decrease for the remaining construction period because construction activities such as building construction, architectural coating, and paving would require less construction equipment. Therefore, DPM generated by project construction is not expected to create conditions where the probability that the Maximally Exposed Individual would contract cancer is greater than 10 in one million. This impact would be less than significant.

d. Would the project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people?
Sensitive receptors in the project vicinity include single-family residences at the project boundaries to the east, south and west. Construction activities would be temporary and transitory and associated odors would cease upon construction completion. Such odors disperse rapidly with distance. Accordingly, the proposed project would not create objectionable odors affecting a substantial number of people during construction, and short-term impacts would be less than significant.
Maison’s Palmdale Boulevard 150, LLC
Tentative Tract Map 83359
30 The project does not include land uses typically associated with odor complaints such as sewage treatment plants, landfills, recycling facilities, and agricultural uses. Vehicles approaching, idling, and leaving the site may release odorous exhaust emissions. Odors of this nature disperse rapidly with distance and do not typically result in odor impacts. Additionally, the project site is located adjacent to Palmdale Boulevard, an arterial road, so vehicle exhaust is already prevalent in the project area.
For these reasons, operational odor impacts would be less than significant.

32 A field reconnaissance survey of the biological study area ;BSAͿ was conducted on September 21, 2022, to document the existing site conditions and evaluate the potential for presence of sensitive biological resources. The Biological Resources Assessment is included as Appendix B. In addition, western Joshua trees were documented on the project site during a western Joshua tree assessment conducted on July 21, 2021. One vegetation community, Yucca brevifolia Woodland ůůŝĂŶĐĞ;:ŽƐŚƵĂƚƌĞĞǁŽŽĚůĂŶĚͿ͕ǁĂƐŝĚĞŶƚŝĨŝĞĚŝŶƚŚĞ^͘dŚŝƐĐŽŵŵƵŶŝƚLJŐĞŶĞƌĂůůLJoccurs in alluvial fans, ridges, and gentle to moderate slopes. Canopy, shrub layer, and herbaceous layer is open to intermittent with perennial grasses and seasonal annuals.
One shallow, ephemeral drainage intersects the project site and adjacent parcel which may generally convey stormwater runoff from the residential development to the south and from Palmdale Avenue to the north during significant rain events. This drainage feature is not identified in the National Hydrogeography Dataset or National Wetlands Institute; however, it is identified as a dashed “blue-line stream” in U.S. Geological Survey topographic maps. Due to the presence of a defined bed and bank, indicated by the break in slope, the California Department of Fish and Wildlife ;CDFWͿ may assert jurisdiction over this drainage. As of December 2022, the portion of the drainage in APN 3023-002-016 is under construction and will be filled in pursuant to Streambed Alteration Agreement EPIMS-LAN-23730-R5 and a new temporary nine-foot dirt swale will be constructed to divert flow from the portion of the drainage on APN 3023-002-184 to a stormwater basin south of the project. Grading associated with the proposed project would eliminate the entirety of the remainder of the drainage, as well as the new temporary swale, approximately
0.75 acre, and replace it with underground storm drains which would outlet into an on-site basin.
The drainage does not provide surface flows to adjacent waters of the State or waters of the U.S. a. Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service?
The literature search identified 19 special status plant species and 31 special status wildlife species within the nine-quad search area. Of the 19 special status plants and 31 special status wildlife species identified, the BSA contains suitable habitat for western Joshua tree and short-joint beavertail cactus as well as California glossy snake, coast horned lizard, burrowing owl, loggerhead shrike, LeConte’s thrasher, and nesting birds. Direct and potentially indirect impacts to these species may occur as a result of construction activities.

The extensive areas of natural habitat to the north would remain suitable for short-joint beavertail cactus and large enough to support robust populations of this species, and proposed activity at the project site would not substantially affect those regional populations. Absent mitigation, impacts to western Joshua trees would be potentially significant and impacts to short- joint beavertail cacti would be less than significant.

and BIO-2 would reduce impacts to western Joshua trees to less than significant and further reduce impacts to short-joint beavertail cacti.
Burrowing Owls
Burrowing owl are a ground-dwelling species that rely on small mammals and large insects for prey.
If owls are present, construction of the project could impact individuals directly by construction- related injury or mortality and permanent removal of habitat, and potentially indirectly in the native habitat to the north due to construction noise, dust, and other human disturbances that may cause a nest to fail. The relatively small project footprint of the site, compared to the amount of available suitable habitat for these species, suggests that site development is unlikely to result in population- level impacts. The presence of extensive areas of natural habitat to the north would remain suitable and large enough to support robust populations of these species, and proposed activity at the project site would not substantially affect those regional populations; therefore, impacts would not be significant. However, implementation of Mitigation Measures BIO-1, BIO-3, and BIO-4 would ensure compliance with federal and State law by avoiding the take of burrowing owls or destruction of their nests.

Significance After Mitigation
Mitigation Measures BIO-1 through BIO-5 require pre-construction survey and biological monitoring be conducted prior to and during ground disturbing activities at the project site. If unanticipated special status species or nesting birds are encountered during ground disturbance, work in the immediate area of the find would stop and a qualified biologist would be contacted immediately.
Implementation of Mitigation Measures BIO-1 through BIO-5 would avoid or reduce the project’s potentially significant impacts to any sensitive species and nesting birds that may be encountered during ground disturbing activities.

b. Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service? The proposed project would directly impact 20 gross acres of Joshua tree woodland, as the entire project is subject to clearing and grading. In addition, the proposed project would also indirectly impact the parcel to the north through excessive dust potentially limiting photosynthesis.
Implementation of Mitigation Measures BIO-1 and BIO-2 would reduce impacts to sensitive natural communities to less than significant.

c. Would the project have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
The on-site drainage is potentially subject to CDFW jurisdiction. The drainage contains a distinct bed and bank that generally conveys surface water flow from stormwater runoff away from the residential development to the south. Grading associated with project construction would eliminate the entirety of the drainage, approximately 0.75 acre, and replace it with underground storm drains that would outlet into an on-site basin. These impacts to jurisdictional areas would be considered significant but mitigable. Of the 0.75 acres to be impacted, the project proponent has already ŵŝƚŝŐĂƚĞĚϬ͘ϰϵĂĐƌĞƐĂƐƉĂƌƚŽĨƚŚĞĂĚũĂĐĞŶƚƉƌŽũĞĐƚ;EPIMS-LAN-23730-R5Ϳ͘ƐƐƵĐŚ, the remaining
0.26 acres still need to be mitigated as part of the proposed project.
Obtaining a permit from CDFW and potentially providing compensatory mitigation, as required by Mitigation Measure BIO-6, would reduce potential direct and indirect impacts to this feature to a less than significant level.
BIO-6 Jurisdictional Waters and Wetlands
Prior to ground disturbance activities, the project proponent shall consult with CDFW. Based on such consultation, if permits are required for the project, appropriate permits shall be obtained prior to disturbance of jurisdictional resources. In addition, compensatory mitigation for impacts to jurisdictional features shall be identified prior to disturbance of the features. A 1:1 mitigation ratio shall be used, unless a higher ratio is required by CDFW. Mitigation may take the form of permittee- responsible on-site or off-site mitigation, or purchasing credits from an approved mitigation bank.
The project proponent shall comply with the compensatory mitigation required and proof of compliance, along with copies of permits obtained from CDFW shall be provided to the City.
Significance After Mitigation
Mitigation Measure BIO-6 requires compensatory mitigation of jurisdictional resources on a 1:1 or greater ratio. Implementation of Mitigation Measure BIO-6 would reduce the project’s potentially significant impacts to jurisdictional resources on the project site.

38 d. Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Wildlife corridors are generally defined as connections between habitat areas that allow for physical and genetic exchange between otherwise isolated animal populations. Such linkages may serve a local purpose, such as between foraging and denning areas, or they may be regional in nature, allowing movement across the landscape. Some habitat linkages may serve as migration corridors, wherein animals periodically move away from an area and then subsequently return. Examples of barriers or impediments to movement include housing and other urban development, roads, fencing, or open areas with little vegetative cover.
As discussed above, project site is surrounded by residential developments on the west, south, and east sides; and the site is bounded to the north by Palmdale Boulevard, a heavily traveled road. The project site is disturbed by dumping, and recreational use by pedestrians and OHVs. Potential wildlife movement on the project site could only occur between the natural habitat block to the north and the surrounding residential developments, which does not significantly contribute to a wildlife movement corridor. Therefore, the proposed project would not interfere with the movement of any native wildlife species. Impacts would be less than significant.

As described above and in the Cultural Resources Report provided by BFSA dated November 11, 2022, no eligible historical resources are documented within the project site. In addition, review of historic registers and inventories indicate that no recorded historical landmarks or points of interest are present within the project area. However, the field survey, conducted on October 25, 2022, revealed a 50- by 50-foot scatter of approximately 100 vent hole/hole-in-top and sanitary cans, glass, and ceramic fragments. A close inspection of the artifact scatter and the surrounding soils indicates that the site has no depth.
The types of cans identified at the site were utilized most commonly after the 1920s and 1930s, the Cultural Resources Study suggests the finding likely dates to between the late 1930s and 1950s, but it is not considered eligible for the CRHR as the scatter does not retain any additional research value given the observable lack of a subsurface component.

If necessary, the evaluation may require preparation of a treatment plan and archaeological testing for CRHR eligibility. If the discovery proves to be eligible for the CRHR and cannot be avoided by the proposed project, additional work, such as data recovery excavation, may be warranted to mitigate any significant impacts to historical resources. The monitors shall submit a report to the City to document compliance within 30 days of completion of ground disturbing activities.

Mitigation Measure CR-1 requires archaeological monitoring be conducted during ground disturbing activities at the project site. If unanticipated archaeological resources are encountered during ground disturbance, work in the immediate area of the find would stop and a qualified archaeologist would be contacted immediately. Implementation of Mitigation Measure CR-1 would avoid or reduce the project’s potentially significant impacts to any archaeological resources that may be found during ground disturbing activities.

c. Would the project disturb any human remains, including those interred outside of formal cemeteries?
The project site is not part of a formal cemetery and is not known to have been used for disposal of historic or prehistoric human remains. There are no known human remains on the site. Therefore, human remains are not expected to be encountered during construction of the proposed project. In the unlikely event that human remains are encountered during project construction, State Health and Safety Code Section 7050.5 requires ground disturbance in the area of the find to halt until the County Coroner has made the necessary findings as to the origin and disposition of the remains pursuant to Public Resources Code Section 5097.98. Compliance with these regulations would ensure the proposed project would not result in significant impacts due to disturbing human remains, and impacts would be less than significant.

a. Would the project result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation?
The proposed project would use nonrenewable and renewable resources for construction and operation of the project. The anticipated use of these resources is detailed in the following subsections. As supported by the discussion below, the proposed project would not result in the wasteful, inefficient, or unnecessary consumption of energy resources that would result in a significant environmental impact.

Initial Study – Mitigated Negative Declaration 45
Construction Energy Demand
The project would require site preparation and grading, building construction, architectural coating, and landscaping and hardscaping. During construction, energy would be consumed in the form of petroleum-based fuels used to power off-road construction vehicles and equipment on the project site, construction worker travel to and from the project site, and vehicles used to deliver materials to the site. The consumption of electricity and natural gas to power the project’s off-road construction vehicles and equipment would be negligible based on standard construction vehicle fleet mix fuel consumption. As shown in Table 11, project construction would require approximately 55,563 gallons of gasoline and approximately 117,207 gallons of diesel fuel. These construction energy estimates are conservative because they assume that the construction equipment used in each phase of construction is operating every day of construction.

These practices would result in efficient use of energy necessary to construct the project. In the interest of cost-efficiency, construction contractors also would not utilize fuel in a manner that is wasteful or unnecessary. Therefore, the project would not involve the inefficient, wasteful and unnecessary use of energy during construction, and the construction-phase impact related to energy consumption would be less than significant.
Operational Energy Demand
Operation of the proposed project would increase area energy demand from greater electricity consumption compared to current conditions on the undeveloped site. Electricity would be used for heating and cooling systems, lighting, appliances, water use, and the overall operation of the project buildings. Gasoline and diesel fuel consumption would be used for motor vehicle travel to and from the project site.
Table 12 summarizes estimated operational energy consumption for the proposed project. As shown therein, project operation would require approximately 210,455 gallons of gasoline and 47,371 gallons of diesel for transportation fuels. The project would require 1.44 GWh of electricity per year from a PV system, therefore, electricity consumption is anticipated to have a net zero draw Maison’s Palmdale Boulevard 150, LLC

b. Would the project conflict with or obstruct a state or local plan for renewable energy or energy efficiency?
New development on the project site would increase energy consumption through electricity to power facilities and heating and cooking. In addition, petroleum is used in motor vehicles used by residents. In 2011, the city adopted an Energy Action Plan to achieve energy independence and energy efficiency and conservation to achieve its GHG emission reduction target of 15 percent by the year 2020, consistent with the State's overall target to reduce GHG emissions statewide to 1990 levels by 2020. Since then, the City of Palmdale released its 2045 General Plan in October 2022, establishing a series of goals and policies to reduce GHG emissions and increase sustainability. The Plan's Sustainability, Climate, and Resilience chapter serve as the Climate Action Plan ;WͿĨŽƌƚŚĞ City of Palmdale. Goals and policies from the 2045 General Plan are described in Section 8, Greenhouse Gas Emissions. In addition, the following goals, policies, and actions related to Energy Action Plan include ;ŝƚLJŽĨWĂůŵĚĂůĞϮϬϭϭͿ:

Goal 3: Promote Renewable Energy Generation and Use.
Measure 3.3: Residential Renewable Energy. Encourage the residential sector to meet energy needs through on-site renewable energy sources.
The project would also be subject to State requirements for energy efficiency, including the mandatory measures for residential development contained in the 2022 CALGreen and Title 24 Building Energy Efficiency Standards. The proposed project would comply with Title 24 Building Energy Efficiency Standards by including renewable energy on-site using a solar PV system to provide power to the single-family residences and community amenities. Additionally, the project would include water-efficient appliances and fixtures in every residential unit, as well as drought tolerant landscaping and water efficient irrigation systems in accordance with the CALGreen standards, which would reduce the project’s water use and energy needed to provide water to the project. These sustainability features align with the energy efficiency goals established in the City’s Energy Action Plan and 2045 General Plan. Therefore, the project would not conflict with or obstruct a State or local plan for renewable energy or energy efficiency, and there would be a less than significant impact.

50 A Geologic and Geotechnical Engineering Investigation was prepared by GeoSoils Consultants Inc. on October 27, 2021, to study the soil conditions of the project site. It was concluded that the project site was considered feasible from a geologic and geotechnical engineering standpoint. The report included recommendations to be followed during grading. The report has been included as Appendix E and attached to this report.
a.1. Would the project 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? a.2. Would the project directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving strong seismic ground shaking? The project site is in a seismically active area of southern California, and therefore, could experience strong ground shaking from local and regional faults. A fault that has ruptured in at least the last 11,700 years is considered to have a higher potential of future seismicity and is considered an active fault by the Alquist-Priolo Earthquake Fault Zoning Act. Faults with evidence of longer earthquake frequency events are considered to have a lower potential of future seismicity. According to California 'ĞŽůŽŐŝĐĂů^ƵƌǀĞLJ;'^Ϳ͕ƚŚĞƉƌŽũĞĐƚƐŝƚĞŝƐŶŽƚůŽĐĂƚĞĚŝŶĂŶůƋƵŝƐƚ-WƌŝŽůŽ&ĂƵůƚŽŶĞ;'^ ϮϬϮϮͿ͘
However, the site is situated in a region subject to strong earthquakes occurring along active faults such as the San Andreas, Nadeau, Cemetery, Little Rock, and Leona Avenue. The closest known active fault to the site is the San Andreas fault which is located at a distance of approximately 3.2 miles southwest of the site. The possibility of ground acceleration, or shaking at the project site, may be considered as approximately similar to the southern California region as a whole.
To reduce geologic and seismic impacts, the City regulates development through the requirements of the CBC. The purpose of the CBC is to establish minimum standards to safeguard the public health, safety, and general welfare through structural strength, means of egress, and general stability by regulating and controlling the design, construction, quality of materials, use and occupancy, location, and maintenance of all building and structures within its jurisdiction. The earthquake design requirements of the CBC consider the occupancy category of the structure, site class, soil classifications, and various seismic coefficients. The CBC provides standards for various aspects of construction, including but not limited to excavation, grading, earthwork, construction, preparation of the site prior to fill placement, specification of fill materials, fill compaction and field testing, retaining wall design and construction, foundation design and construction, and seismic requirements. It includes provisions to address issues such as, but not limited to, ground shaking. In accordance with California law, project design and construction would be required to comply with provisions of the CBC. Because the project would comply with the CBC and because the project would not exacerbate existing ground shaking hazards, impacts related to seismically induced ground shaking and fault rupture would be less than significant.

a.3. Would the project directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving seismic-related ground failure, including liquefaction? a.4. Would the project directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving landslides?
Liquefaction is a process whereby soil is temporarily transformed to fluid form during intense and prolonged ground shaking or because of a sudden shock or strain. Typically, liquefaction occurs in areas where there are loose soils and the depth to groundwater is less than 50 feet from the surface. The project site is not located within a mapped liquefaction or landslide area identified by the California Geological Survey ;'^ϮϬϮϮͿ͘In addition, according to the Geotechnical Engineering Investigation, the site is underlain by dense alluvium and groundwater levels are below at least 50 ĨĞĞƚ;Appendix EͿ͘ƐĂƌĞƐƵůƚ͕ƚŚĞƐŝƚĞŝƐŶŽƚƐƵďũĞĐƚƚŽůŝƋƵĞĨĂĐƚŝŽŶ͘Due to the relatively flat topography of the site and surrounding areas, the project site is not at risk of landslides.
Furthermore, design and construction of the project would conform to the current seismic design provisions of the CBC, which incorporates the latest seismic design standards for structural loads and materials, as well as provisions from the National Earthquake Hazards Reduction Program, to mitigate losses from an earthquake, including liquefaction, and provide for the latest in earthquake safety. While the project would be susceptible to seismic activity given its location within a seismically active area, the project site is not susceptible to liquefaction or landslides and would be required to minimize this risk, to the extent feasible, through the incorporation of applicable CBC standards. Therefore, the project would not result in substantial adverse impacts related to liquefaction or landslides, and impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project result in substantial soil erosion or the loss of topsoil? The proposed project involves the construction of a new single-family residential community on a project site that is currently vacant. Construction activities have the potential to result in soil erosion, particularly during grading and excavation activities. Fugitive dust caused by strong wind and/or earth-moving operations during construction would be minimized through compliance with SCAQMD Rule 403, which prohibits visible particulate matter from crossing property lines. Standard practices to control fugitive dust emissions include watering of active grading sites, covering soil stockpiles with plastic sheeting, and covering soils in haul trucks with secured tarps. In addition, the potential for project construction activities to result in increased erosion and sediment transport by stormwater to surface waters would be minimized because the project would be required to comply with a Construction General Permit, which is issued by the State Water Resources Control Board ;^tZͿ͘dŚĞŽŶƐƚƌƵĐƚŝŽŶ'ĞŶĞƌĂůWĞƌŵŝƚƌĞƋƵŝƌĞƐƚŚĞĚĞǀĞůŽƉŵĞŶƚŽĨĂ^ƚŽƌŵtĂƚĞƌWŽůůƵƚŝŽŶ WƌĞǀĞŶƚŝŽŶWůĂŶ;^tWWWͿ͕ǁŚŝĐŚŽƵƚůŝŶĞƐDWƐƚŽƌĞĚƵĐĞĞƌŽƐŝŽŶĂŶĚƚŽƉƐŽŝůůŽƐƐĨƌŽŵƐƚŽƌŵǁĂƚĞƌ ƌƵŶŽĨĨ;ĂůƐŽƌĞĨĞƌƚŽƚŚĞdiscussion in Section 10, Hydrology and Water QualityͿ͘ŽŵƉůŝĂŶĐĞǁŝƚŚ the Construction General Permit would ensure that BMPs are implemented during construction and minimize substantial soil erosion or the loss of topsoil. Upon completion of construction, the project site would be stabilized with landscaping and paving, and operational activities would not result in soil erosion. Therefore, impacts would be less than significant.

52 c. Would the project be located 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?
Lateral spreading is the horizontal movement or spreading of soil toward an open face. Lateral spreading may occur when soils liquefy during an earthquake event, and the liquefied soils with overlying soils move laterally to unconfined spaces. Subsidence is the sudden sinking or gradual downward settling of the earth’s surface with little or no horizontal movement. Subsidence is caused by a variety of activities that include, but are not limited to, withdrawal of groundwater, pumping of oil and gas from underground, the collapse of underground mines, liquefaction, and hydrocompaction. Collapse potential refers to the potential settlement of a soil under existing stresses upon being wetted.
As discussed under Impacts 7.a.1 through 7.a.4, although the proposed project is in a seismically active area, the project site is not located on unstable soils or a geologic unit at risk for liquefaction or landslides. The project site consists of relatively flat land that is surrounded by developed land with no significant slopes that would present a landslide hazard. Furthermore, construction and operation of the project would not involve activities known to cause or trigger subsidence and is not anticipated to adversely affect soil stability or increase the potential for local or regional landslides, subsidence, liquefaction, or collapse. The project would comply with CBC requirements. Because the project would not create or exacerbate conditions related to unstable soils, impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
d. Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? Expansive soils are highly compressible, clay-based soils that tend to expand as they absorb water and shrink as water is drawn away. According to the USDA online Web Soil Survey map the soil on the project site is made up of loamy sand and loamy fine sand with a 0 to 2 ƉƌĞĐĞŶƚƐůŽƉĞ;h^ ϮϬϮϮͿ͘The Geotechnical Engineering Investigation concluded that alluvium underlies the project site ĂŶĚĐŽŶƐŝƐƚƐŽĨƐĂŶĚĂŶĚŐƌĂǀĞůůLJƐĂŶĚ͕ǁŝƚŚǀĂƌŝĂďůĞĂŵŽƵŶƚƐŽĨƐŝůƚ;ƉƉĞŶĚŝdž EͿ͘dŚĞĂůůƵǀŝƵŵŝƐ slightly moist and dense. Sandy and gravelly soils do not typically contain significant levels of clay that could adversely affect building footings.
Furthermore, the proposed project would be required to comply with the most recent CBC requirements, which have been developed to property safeguard structures and occupants from land stability hazards, such as expansive soils. Therefore, impacts related to expansive soils would be less than significant.
LESS THAN SIGNIFICANT IMPACT
e. Would the project have 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 project would be served by the City’s existing sewer system and no septic tanks are proposed for the project. Therefore, there is no potential for adverse effects due to soil incompatibility with septic tanks. No impact would occur.

f. Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
Paleontological resources, or fossils, are the evidence of once-living organisms preserved in the rock record.

It is possible to evaluate the potential for geologic units to contain scientifically important paleontological resources, and therefore evaluate the potential for impacts to those resources and provide mitigation for paleontological resources if they are discovered during construction of a development project.
A paleontological resource assessment was conducted by BFSA on October 25, 2022 ;ƉƉĞŶĚŝdžϮͿ, the full assessment is included as Appendix E. The paleontological assessment of the project included a review of paleontological literature and fossil locality records for a previous project in the area; a review of the underlying geology; and recommendations to mitigate impacts to potential paleontological resources.
The paleontological resources assessment confirmed the potential for paleontological resources to exist on the project site due to the presence of thin, Holocene alluvial deposits mapped at the surface of the project. Construction activities may result in the destruction, damage, or loss of undiscovered paleontological resources. Therefore, impacts to paleontological resources would be potentially significant. Mitigation Measure GEO-1 requires a mitigation program that establishes monitoring and a recovery protocol in the event that prehistoric deposits are discovered.
Mitigation Measure
GEO-1 Paleontological Resource Impact Mitigation Program Prior to the issuance and approval of grading permits for the project the applicant shall submit a WĂůĞŽŶƚŽůŽŐŝĐĂůZĞƐŽƵƌĐĞ/ŵƉĂĐƚDŝƚŝŐĂƚŝŽŶWƌŽŐƌĂŵ;WZ/DWͿ͘dŚĞWZ/DWƐŚall include the following:
1. Prior to initiation of any grading, drilling, and/or excavation activities, a preconstruction meeting shall be held and attended by the paleontologist of record, representatives of the grading contractor and subcontractors, the project owner or developer, and a representative of the lead agency. The nature of potential paleontological resources shall be discussed, as well as the protocol that is to be implemented following the discovery of any fossiliferous materials.
2. Monitoring of mass grading and excavation activities in areas identified as likely to contain paleontological resources shall be performed by a qualified/project paleontologist or paleontological monitor. Monitoring shall be performed starting at the surface on a full-time basis; Holocene alluvial deposits should be monitored parttime at the discretion of the project paleontologist. The timing and duration of the monitoring of excavation activities within the alluvial fan deposits shall be at the discussion of the project paleontologist based on the geological conditions observed by the paleontological monitor and/or the project paleontologist.

54 3. Paleontological monitors shall be equipped to salvage fossils as they are unearthed to avoid construction delays. The monitor shall be empowered to temporarily halt or divert equipment to allow removal of abundant or large specimens in a timely manner. Monitoring may be reduced if the potentially fossiliferous units are not present in the subsurface, or, if present, are determined upon exposure and examination by qualified paleontological personnel to have low potential to contain fossil resources. The monitor shall notify the project paleontologist, who will then notify the concerned parties of the discovery.
4. Paleontological salvage during trenching and boring activities is typically from the generated spoils and does not delay the trenching or drilling activities. Fossils will be collected and placed in cardboard flats or plastic buckets and identified by field number, collector, and date collected. Notes shall be taken on the map location and stratigraphy of the site, which is photographed before it is vacated, and the fossils are removed to a safe place. On mass grading projects, discovered fossil sites shall be protected by flagging to prevent them from being ŽǀĞƌƌƵŶďLJĞĂƌƚŚŵŽǀĞƌƐ;ƐĐƌĂƉĞƌƐͿ before salvage begins. Fossils will be collected in a similar manner, with notes and photographs being taken before removing the fossils. Precise location of the site is determined with the use of handheld GPS units.

For large fossils, use of the contractor’s construction equipment may be solicited to help remove the jacket to a safe location.
5. Isolated fossils shall be collected by hand, wrapped in paper, and placed in temporary collecting flats or five-gallon buckets. Notes will be taken on the map location and stratigraphy of the site, which is photographed before it is vacated, and the fossils are removed to a safe place.
6. Particularly small invertebrate fossils typically represent multiple specimens of a limited number of organisms, and a scientifically suitable sample can be obtained from one to several five-gallon buckets of fossiliferous sediment. If it is possible to dry screen the sediment in the field, a concentrated sample may consist of one or two buckets of material. For vertebrate fossils, the test is usually the observed presence of small pieces of bones within the sediments. If present, multiple five-gallon buckets of sediment can be collected and returned to a separate facility to wet-screen the sediment.

The baseline against which these changes are measured originates in historical records that identify temperature changes that occurred in the past, such as during previous ice ages. The global climate is changing continuously, as evidenced in the geologic record which indicates repeated episodes of substantial warming and cooling. The rate of change has typically been incremental, with warming or cooling trends occurring over the course of thousands of years. The past 10,000 years have been marked by a period of incremental warming, as glaciers have steadily retreated across the globe. However, scientists have observed acceleration in the rate of warming over the past 150 years.

California
Based on a review of CARB’s California Greenhouse Gas Inventory for the years between 2000-2020, California produced 369.2 MMT of CO2e in 2020, which is 35.3 MMT of CO2e lower than 2019 levels.
The 2019 to 2020 decrease in emissions is likely due in large part to the impacts of the COVID-19 pandemic. The major source of GHG emissions in California is the transportation sector, which comprises 37 percent of the State’s total GHG emissions. The industrial sector is the second largest source, comprising 20 percent of the State’s GHG emissions while electric power accounts for approximately 16 percent. The magnitude of California’s total GHG emissions is due in part to its large size and large population compared to other states. However, a factor that reduces California’s per capita fuel use and GHG emissions as compared to other states is its relatively mild climate. In 2016, California achieved its 2020 GHG emission reduction target of reducing emissions to 1990 levels as emissions fell below 431 MMT of CO

62 In addition to reducing emissions from transportation, energy, and industrial sectors, the 2022 Update includes emissions and carbon sequestration in NWL and explores how NWL contributes to long-term climate goals. Under the Scoping Plan Scenario, California’s 2030 emissions are anticipated to be 48 percent below 1990 levels, representing an acceleration of the current SB 32 target. Cap-and-Trade regulation continues to play a large factor in the reduction of near-term emissions for meeting the accelerated 2030 reduction target. Every sector of the economy will need to begin to transition in this decade to meet our GHG emissions reduction goals and achieve carbon neutrality no later than 2045. The 2022 Update approaches decarbonization from two perspectives, managing a phasedown of existing energy sources and technologies, as well as increasing, developing, and deploying alternative clean energy sources and technology.

Significance Thresholds
Based on Appendix G of the CEQA Guidelines, impacts related to GHG emissions from the project would be significant if the project would:
Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment; or
Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing GHG emissions.
The majority of individual projects do not generate sufficient GHG emissions to directly influence climate change. However, physical changes caused by a project can contribute incrementally to cumulative effects that are significant, even if individual changes resulting from a project are limited. The issue of climate change typically involves an analysis of whether a project’s contribution towards an impact would be cumulatively considerable. “Cumulatively considerable” means that the incremental effects of an individual project are significant when viewed in connection with the ĞĨĨĞĐƚƐŽĨƉĂƐƚƉƌŽũĞĐƚƐ͕ŽƚŚĞƌĐƵƌƌĞŶƚƉƌŽũĞĐƚƐ͕ĂŶĚƉƌŽďĂďůĞĨƵƚƵƌĞƉƌŽũĞĐƚƐ; Y'ƵŝĚĞůŝŶĞƐ͕

Section 15064.4 of the CEQA Guidelines recommends that lead agencies quantify GHG emissions of projects and consider several other factors that may be used in the determination of significance of GHG emissions from a project, including the extent to which the project may increase or reduce GHG emissions; whether a project exceeds an applicable significance threshold; and the extent to which the project complies with regulations or requirements adopted to implement a plan for the reduction or mitigation of GHG emissions. The City of Palmdale has prepared a qualified CAP pursuant to CEQA Guidelines ^ĞĐƚŝŽŶϭϱϭϴϯ͘ϱ;ďͿ͘dŚĞWƐĞƌǀĞƐĂƐa “qualified plan for the reduction of greenhouse gases” and provides a mechanism for tiering and streamlining of GHG emissions analysis for projects that are consistent with such a plan.

by 2045 contained in the 2022 Scoping Plan. To achieve these reductions, the City’s CAP has established per-service population emissions targets that are used for this analysis, which are: 2 MT CO2e per service population by 2030; 1.3 MT CO2e per service population by 2035; and 1.2 MT CO2e per service population by 2045. Per-service population emissions are calculated by dividing total community emissions by the residents plus employees.
a. Would the project generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment?
The City of Palmdale CAP is a qualified GHG reduction plan consistent with the requirements of CEQA Guidelines Section 15183.5. In accordance with the CAP, project GHG emissions would be less than significant if it can be demonstrated that the project would be consistent with the CAP and generate less than 2 MT CO
2e per service population per year.
Project construction would generate temporary short-term GHG emissions through travel to and from the worksite and from the operation of construction equipment such as graders, backhoes, and generators. Construction of the project would generate approximately 1,546 MT CO 2e over the
entire construction period. As shown in Table 13, the proposed project’s amortized construction- related emissions would be 52 MT CO2e.

Significance After Mitigation
To implement Mitigation Measure GHG-1, the project applicant may choose to apply a wide variety of GHG emission reduction measures, including carbon offsets, to reduce project-related emissions to 1,254 MT of CO2e per year. Therefore, implementation of Mitigation Measure GHG-1 would reduce project-related emissions below the threshold of significance of 1,254 MT of CO2e per year or 2 MT of CO2e per service population per year. Impacts would be less than significant with mitigation incorporated.

74 a. Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Project construction would involve the use of potentially hazardous materials such as vehicle fuels and fluids that could be released should an accidental leak or spill occur. However, standard construction BMPs for the use and handling of such materials, such as the use of secondary containment, would be implemented to avoid or reduce the potential for such conditions to occur.
Furthermore, any use of potentially hazardous materials utilized during construction of the proposed project would be subject to all local, State, and federal regulations regarding the handling of potentially hazardous materials. The transport, use, and storage of hazardous materials during construction of the project would be subject to all applicable State and federal laws, such as the Hazardous Materials Transportation Act, Resource Conservation and Recovery Act, California Hazardous Material Management Act, and hazardous waste management and cleanup under CCR Title 22. Therefore, project construction would not create a significant hazard to the public and environment through the routine transport, use, or disposal of hazardous materials.
Operation of the proposed project would likely involve the use of common materials in the regular maintenance of homes and landscaping, such as cleaning and degreasing solvents, fertilizers, and pesticides. However, these maintenance activities would only require minor quantities of such products and would not involve the use of extremely hazardous substances. Use of these materials would be subject to compliance with existing regulations, standards, and guidelines established by the federal, State, and local agencies related to storage, use, and disposal of hazardous materials.
The transport, use, and storage of hazardous materials during operation of the project would be subject to all applicable State and federal laws, such as the Hazardous Materials Transportation Act, Resource Conservation and Recovery Act, California Hazardous Material Management Act, and hazardous waste management and cleanup under CCR Title 22. Other than small quantities of materials used in the maintenance of the residential community, operation of the proposed project would not involve the use or storage of substantial quantities of hazardous materials, nor would the project generate large quantities of hazardous waste. Therefore, operation of the proposed project would not create a significant hazard to the public or the environmental through the routine transport, use, or disposal of hazardous materials and impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project 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?
As described above, construction of the project would involve the use of potentially hazardous materials such as vehicle fuels and fluids that could be released should an accidental leak or spill occur. However, as further discussed in Section 10, Hydrology and Water Quality, the SWPPP for the proposed project would include standard construction BMPs for the use and handling of such materials to avoid or reduce the potential for such conditions to occur. Typical construction BMPs include secondary containment and special storage for hazardous materials used on-site, the use of drip pans under vehicles and equipment, and provisioning of spill kits and cleanup plans in the event of an accidental spill. The transport, use, and storage of hazardous materials during construction of the project would be conducted in accordance with all applicable State and federal laws, such as the Hazardous Materials Transportation Act, Resource Conservation and Recovery Act, California Hazardous Material Management Act, and hazardous waste management and cleanup under CCR Title 22. Therefore, project construction would not create a significant hazard to the public or Environmental Checklist

environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment.
Operation of the residential homes would not involve the use or storage of significant quantities of hazardous materials. Therefore, project operation is not anticipated to create a significant hazard to the public or environment through the accidental release of hazardous materials. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
c. Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within 0.25 mile of an existing or proposed school? The nearest school facilities to the project site are Chaparral Prep Academy approximately one mile south of the project site, Mesquite Elementary School 1.2 mile southwest of the project site, and Buena Vista Elementary School 1.6 miles south of the project site.
During construction of the proposed project, hazardous and potentially hazardous materials would be utilized for the transport and operation of vehicles and machinery. As discussed above, the transport, use, and storage of hazardous materials during the construction of the project would be conducted in accordance with all applicable State and federal laws, such as the Hazardous Materials Transportation Act, Resource Conservation and Recovery Act, California Hazardous Material Management Act, and hazardous waste management and cleanup under CCR Title 22. Compliance with these regulations would reduce the potential of accidental spills or hazardous emissions during construction. Furthermore, operation and maintenance of the proposed project would only involve the use of common cleaning and landscape maintenance materials comparable to those materials already in use in the project site vicinity.
Although the project site is in proximity to several schools, none are within 0.25 mile of the site, and the project would not regularly store or use significant quantities of hazardous materials, nor would it generate large quantities of hazardous waste. Therefore, the project would not emit hazardous emissions or handle hazardous or acutely hazardous materials that could result in significant impacts to nearby schools. Impacts would be less than significant.

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? The project site is not located within two miles of a public airport or within an airport land use plan.
The airport nearest to the project site is the Palmdale Regional Airport located approximately four miles to the northwest. Furthermore, there are no private airstrips in the vicinity of the project site.
Therefore, the project would not result in safety hazards related to airports for people residing or working at the project site and its vicinity. No impact would occur.
NO IMPACT
f. Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
The proposed project would involve the construction of 191 single-family housing units. During construction, temporary and occasional lane closures on East Palmdale Boulevard may be required, but two-way traffic would be maintained on these roadways and at construction entry points.
Pursuant to Chapter 14.40 of the PMC, as part of the City’s requirements for obtaining an excavation and traffic control permit, the contractor is required to submit to the City a construction work site traffic control plan for any street/lane closures for review and approval prior to the commencement of construction activities. The submittal and approval of the construction traffic control plan would ensure that construction would not interfere with local traffic or emergency response and evacuation procedures.
Vehicles, including emergency response vehicles, would be able to access the project site via the main entrance off East Palmdale Boulevard. The proposed project would not modify East Palmdale Boulevard, other than by adding the entrances to the project site. In addition, the project would not result in inadequate emergency access because it would be subject to Fire Department review of site plans, site construction, and the actual structures prior to occupancy to ensure that required fire protection safety features, including building sprinklers and emergency access, are implemented. Therefore, the proposed project would not impair implementation of or physically interfere with an adopted emergency response or evacuation plan. Potential impacts would be less than significant.

80 a. Would the project violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? Construction of the proposed project could result in soil erosion due to earth-moving activities such as excavation, grading, soil stockpiling, and the generation of water pollutants including trash, construction materials, and equipment fluids. Prior to initiation of construction, the project would be required to obtain coverage under a Construction General Permit to comply with Clean Water ĐƚEĂƚŝŽŶĂůWŽůůƵƚŝŽŶŝƐĐŚĂƌŐĞ

Under the conditions of the Construction General Permit and the Water Quality Control Plan, the developer would be required to eliminate or reduce non-storm water discharges, develop and implement a SWPPP for the project construction activities, and perform inspections of the storm water pollution prevention measures and control practices to ensure conformance with the site SWPPP. The Construction General Permit prohibits the discharge of materials other than storm water discharges and prohibits all discharges that contain a hazardous substance in excess of reportable quantities established by 40 CFR 117.3 or 40 CFR 302.4. The General Permit also specifies that construction activities must meet all applicable provisions of Sections 30 and 402 of the Clean Water Act. Compliance with the permit would require the development and implementation of a SWPPP and associated BMPs during project construction.
Conformance with Section 402 of the Clean Water Act would ensure that construction of the proposed project would not violate any water quality standards or waste discharge requirements. In addition, Chapter 14.05 Section 14.05.080 of the PMC requires project applicants to complete a soil management report in order to reduce runoff.
The requirements of the applicable City and State ordinances are intended to protect water quality and support attainment of water quality standards in downstream receiving water bodies.
Therefore, operation of the project would not violate any water quality standards or waste discharge requirements, nor would it otherwise substantially degrade water quality. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin?
The project site lies above the Antelope Valley Groundwater Basin. Though the project would increase the amount of impervious surface on the site compared to existing conditions, the incorporation of the biofiltration system and underground vault would ensure stormwater is captured and treated on the project site, from which it would be infiltrated into the ground.
The project site lies within the service boundaries of the WĂůŵĚĂůĞtĂƚĞƌŝƐƚƌŝĐƚ;WtͿ͘ PWD primarily sources its water supply from California Aqueduct, Littlerock Dam, the Antelope Valley 'ƌŽƵŶĚǁĂƚĞƌĂƐŝŶ͕ĂŶĚƚŚĞ>ĞƐůŝĞK͘ĂƌƚĞƌtĂƚĞƌdƌĞĂƚŵĞŶƚWůĂŶƚ;>KtdWͿ. As discussed in Section 18, Utilities and Service Systems, the proposed project’s water demand would not substantially affect the PWD’s supplies. According to its 2020 Urban Water Management Plan, PWD would be able to provide reliable water supplies for an average year ;Wt2021Ϳ. However, PWD anticipates that during single-dry year conditions, demands would exceed existing supplies starting in 2030 and that during multiple dry year conditions, demands would exceed existing supplies ƐƚĂƌƚŝŶŐŝŶϮϬϰϱ;WtϮϬϮϬͿ.

Such measures include use of the PWD Water Use Rebate Program, repairing water leaks, prohibiting outside car washing, restricted landscape watering, shut off of all fountains or outdoor aesthetic water features, and prohibiting the watering of hardscapes. Therefore, it is anticipated that existing supplies in combination with identified future and potential water supply opportunities and demand reduction responses would enable PWD to meet all future water demands under all hydrologic conditions through the end of the planning period.
Therefore, operational water use associated with the proposed project would not significantly deplete groundwater supplies or impede sustainable groundwater management of the Antelope Valley Groundwater Basins. Impacts would be less than significant.

c.(iv) Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would impede or redirect flood flows? The project would not alter the course of a stream or river since the project site and surrounding area do not contain water bodies. However, the project would alter internal site drainage through the addition of impervious surfaces, which could increase stormwater runoff volume and flow.
Drainage improvements for the development would consist of catch basins connected to underground storm drain which outlets into a detention basin located at lot 8 of the TTM. This basin would accept flows from the community and detain from flowing offsite while also infiltrating water back into the groundwater basin. Should a large storm event occur, the basin has been designed with an overflow pump to pump water so that all standing water is removed from the basin within 72-hours. As shown in Figure 3, new drainage features would be constructed on-site to minimize potential flooding and offsite stormwater flows, in accordance with the requirements of the PMC Section 08.04.2ϬϬ;ĚŽƉƚŝŽŶŽĨĚŵŝŶŝƐƚƌĂƚŝǀĞWƌŽǀŝƐŝŽŶƐĨŽƌƚŚĞPalmdale Building Code, Plumbing Code, Mechanical Code, Electrical Code, Residential Code and Green Building CŽĚĞͿ.

Furthermore, the SWMP includes an assessment of whether drainage alterations would create a Hydrologic Condition of Concern due to hydromodification, such as changes in watershed hydrologic processes and runoff that result in increased streamflow and sediment transport. As part of the project’s final design review, the project would be required to submit a SWMP demonstrating adequate stormwater retention using BMPs.
The project would implement BMPs to capture and retain stormwater on-site, for compliance with the PMC and MS4 Permit requirements. Implementation of BMPs would slow the velocity of water and allow sediment and debris to settle out of the water column, as well as capture stormwater on the site, thereby minimizing the potential for downstream flooding, erosion/siltation, pollution, or exceedances of stormwater drainage system capacity. Impacts would be less than significant.

e. Would the project conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?
As discussed under Threshold 10a above, project construction and operational activities would be required to comply with the LARWQCB’s Water Quality Control Plan, NPDES Construction General Permit, and MS4 Permit by preparing and adhering to a SWPPP and SWMP. With implementation of the required SWPPP and SWMP, the proposed project would adequately treat, detain, and control stormwater flows on the project site and would not conflict with or obstruct the LARWQCB Water Quality Control Plan. As discussed under Threshold 10b, the project would receive water from the Antelope Valley Basin through service provided by Palmdale Water Company. These basins are adjudicated, and water demand generated by the proposed project would not conflict with or obstruct the sustainable management of these basins. The project site lies above the Antelope Valley Basin, which was adjudicated in 2015 and is controlled by a court-mandated water management plan to ensure its long-term sustainability. The proposed residential uses on the project site would not be point source generators of water pollutants that could affect the Antelope Valley Basin, and the project does not propose ground water extraction. Therefore, project construction and operation would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. Impacts would be less than significant.

Noise Setting
Overview of Noise
Sound is a vibratory disturbance created by a moving or vibrating source, which is capable of being detected by the hearing organs. Noise is defined as sound that is loud, unpleasant, unexpected, or undesired and may therefore be classified as a more specific group of sounds. The effects of noise on people can include general annoyance, interference with speech communication, sleep ĚŝƐƚƵƌďĂŶĐĞ͕ĂŶĚ͕ŝŶƚŚĞĞdžƚƌĞŵĞ͕ŚĞĂƌŝŶŐŝŵƉĂŝƌŵĞŶƚ;ĂůƚƌĂŶƐϮϬϮϬĂͿ͘ H

Decibels are measured on a logarithmic scale that quantifies sound intensity in a manner similar to the Richter scale used to measure earthquake magnitudes. A doubling of the energy of a noise source, such as doubling of traffic volume, would increase the noise level by 3 dB; dividing the energy in half would result in a 3 dB decrease ;ĂůƚƌĂŶƐ ϮϬϮϬĂͿ͘
Human perception of noise has no simple correlation with sound energy: the perception of sound is not linear in terms of dBA or in terms of sound energy. Two sources do not “sound twice as loud” as Maison’s Palmdale Boulevard 150, LLC

SOUND PROPAGATION AND SHIELDING
Sound changes in both level and frequency spectrum as it travels from the source to the receiver.
The most obvious change is the decrease in the noise level as the distance from the source increases.

Natural terrain features, such as hills and dense woods, and man-made features, such as buildings and walls, can significantly alter noise levels.

max is the highest noise level within the sampling period, and the Lmin is the lowest noise level within the measuring period. Normal conversational levels are in the 60 to 65-dBA Leq range; ambient noise levels greater than 65 dBA Leq ĐĂŶŝŶƚĞƌƌƵƉƚĐŽŶǀĞƌƐĂƚŝŽŶƐ;&ĞĚĞƌĂůdƌĂŶƐŝƚĚŵŝŶŝƐƚƌĂƚŝŽŶ&d ϮϬϭϴͿ͘

Groundborne Vibration
Groundborne vibration of concern in environmental analysis consists of the oscillatory waves that move from a source through the ground to adjacent structures. The number of cycles per second of oscillation makes up the vibration frequency, described in terms of Hz. The frequency of a vibrating object describes how rapidly it oscillates. The normal frequency range of most groundborne vibration that can be felt by the human body starts from a low frequency of less than 1 Hz and goes to a high of about 200 Hz ;ƌŽĐŬĞƌϮϬϬϳͿ͘
While people have varying sensitivities to vibrations at different frequencies, in general they are most sensitive to low-frequency vibration. Vibration in buildings, such as from nearby construction activities, may cause windows, items on shelves, and pictures on walls to rattle. Vibration of building components can also take the form of an audible low-frequency rumbling noise, referred to as groundborne noise. Groundborne noise is usually only a problem when the originating vibration spectrum is dominated ďLJĨƌĞƋƵĞŶĐŝĞƐŝŶƚŚĞƵƉƉĞƌĞŶĚŽĨƚŚĞƌĂŶŐĞ;ϲϬƚŽϮϬϬ,njͿ͕ŽƌǁŚĞŶ foundations or utilities, such as sewer and water pipes, physically connect the structure and the ǀŝďƌĂƚŝŽŶƐŽƵƌĐĞ;&dϮϬϭϴͿ͘ůƚŚŽƵŐŚŐƌŽƵŶĚďŽƌŶĞǀŝďƌĂƚŝŽŶŝƐƐŽŵĞƚŝŵĞƐŶŽƚŝĐĞĂďůĞŝŶŽutdoor environments, it is almost never annoying to people who are outdoors.

Project Area Noise Setting
The most common source of noise in the project site vicinity is vehicular traffic from East Palmdale Boulevard and 47th Street East. To characterize ambient sound levels at and near the project site, three 15-minute sound level measurements and one 24-hour sound level measurement were conducted on Wednesday, September 21, 2022.

Sections 5 and 6 of manual addresses the federal guidelines used to evaluate a project for potential vibration impacts.

These guidelines are advisory and should be used to assess the impacts of ground borne vibrations created from transit and construction sources.
California Building Code
California Code of Regulations Title 24, Building Standards Administrative Code, Part 2, and the California Building Code codify the state noise insulation standards. These noise standards apply to new construction in California to control interior noise levels as they are affected by exterior noise sources. The regulations specify that interior noise levels for residential and school land uses should not exceed 45 CNEL.
City of Palmdale General Plan
The State of California requires each city and county to adopt a Noise Element as part of its General Plan. Such Noise Elements must contain a Land Use/ Noise Compatibility Matrix. The objective of noise compatibility guidelines is to provide the community with a means of judging the noise Environmental Checklist

The matrix is used to determine whether a proposed new use would be compatible with the ambient noise environment in which it is proposed as well as whether or not the proposed new use would create noise compatibility conflicts with established uses. The compatibility table, shown in Figure 5, illustrates the ranges of community noise exposure in terms of what is “normally acceptable,” “conditionally acceptable,” “normally unacceptable,” and “clearly unacceptable.”
Denotation of a land use as “normally acceptable” implies that the highest noise level in that exposure level is the maximum desirable for existing or conventional construction that does not incorporate any special acoustical treatment. In general, evaluation of land use that falls into the “normally acceptable,” “conditionally acceptable,” or “normally unacceptable” noise environments should analyze other potential factors that would affect the noise environment. These include consideration of the types of noise source, the sensitivity of the noise receiver, the noise reduction likely to be provided by structures, and the degree to which the noise source may interfere with speech, sleep, or to other activities characteristic of the land use. Generally, the City’s Land Use/Noise Compatibility Matrix is used as a guide to define where placement of certain land uses is considered acceptable. The Noise Element of the City’s current General Plan also contains policies to maintain an acceptable noise environment in the city. Goals and policies from the proposed Plan relating to noise are listed in the impact analysis discussions in Section 4, Impact Analysis.
Palmdale Municipal Code
The City also implements and enforces noise control through the PMC Chapter 9.18 ;Disturbing, Excessive, Loud, or Offensive NoiseͿ, which sets both daytime and nighttime sound level limits for residential and commercial zones; prohibits any person or property owner in the city from creating any loud, unnecessary, or unusual noise which unreasonably disturbs the peace and quiet of any neighborhood or which causes discomfort or annoyance to any reasonable person of normal sensitiveness residing in the area.
PMC Chapter 8.28 ;Building Construction Hours of Operation and Noise ControlͿ, prohibits any person or property owner in the City to perform any construction or repair work on any Sunday, or any other day after 8:00 p.m. or before 6:30 a.m., in any residential zone or within 500 feet of any residence, hotel, motel or recreational vehicle park.

a. Would the project result in 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? The following discussions address the potential noise level increases associated with construction and operation of the project.
Construction Noise
Pursuant to Chapter 8.28 ;ƵŝůĚŝŶŐŽŶƐƚƌƵĐƚŝŽŶ,ŽƵƌƐŽĨKƉĞƌĂƚŝŽŶĂŶĚEŽŝƐĞŽŶƚƌŽůͿ of the PMC, noise generated by construction activities is not prohibited if it occurs on Monday through Saturday, between the hours of 6:30 a.m. to 8:00 p.m. In addition, the FTA-recommended criterion of 80 dBA L

Using RCNM, construction noise levels were estimated at noise sensitive receivers near the project site. RCNM provides reference noise levels for standard construction equipment, with an attenuation rate of 6 dBA per doubling of distance for stationary equipment.
Variation in power imposes additional complexity in characterizing the noise source level from construction equipment. Power variation is accounted for by describing the noise at a reference distance from the equipment operating at full power and adjusting it based on the duty cycle of the activity to determine the L

equipment mix, depending on the work to be accomplished during that phase. Each phase also has its own noise characteristics; some will have higher continuous noise levels than others, and some have high-impact noise levels.
Construction activity would result in temporary noise in the project site vicinity, exposing surrounding nearby receivers to increased noise levels. Construction noise would typically be higher ĚƵƌŝŶŐƚŚĞŚĞĂǀŝĞƌƉĞƌŝŽĚƐŽĨŝŶŝƚŝĂůĐŽŶƐƚƌƵĐƚŝŽŶ;ŝ͘Ğ͕͘ƐŝƚĞ ƉƌĞƉĂƌĂƚŝŽŶĂŶĚŐƌĂĚŝŶŐͿĂŶĚǁŽƵůĚďĞ ůŽǁĞƌĚƵƌŝŶŐƚŚĞůĂƚĞƌĐŽŶƐƚƌƵĐƚŝŽŶƉŚĂƐĞƐ;ŝ͘Ğ͕͘ďƵŝůĚŝŶŐĐŽŶƐƚƌƵĐƚŝŽŶĂŶĚƉĂǀŝŶŐͿ͘dLJƉŝĐĂůŚĞĂǀLJ construction equipment during project grading could include dozers, loaders, graders, and dump trucks. It is assumed that diesel engines would power all construction equipment. Construction equipment would not all operate at the same time or location. In addition, construction equipment would not be in constant use during the 8-hour operating day.
Project construction would occur nearest to the single-family residences within the southern and western portion of the project site. Over the course of a typical construction day, construction equipment would be located as close as 15 feet to the properties but would typically be located at an average distance farther away due to the nature of construction and the lot size of the project.
For example, during a typical construction day when performing construction near these residences, the equipment may opĞƌĂƚĞĂĐƌŽƐƐĂŚŽƌŝnjŽŶƚĂůĚŝƐƚĂŶĐĞ;ϭϱƚŽƐĞǀĞƌĂůŚƵŶĚƌĞĚ ĨĞĞƚͿĨƌŽŵĂŶĞĂƌďLJ noise receiver. Therefore, it is assumed that over the course of a typical construction day the construction equipment would operate at an average distance of 100 feet from the single-family residences to the west and south.
Construction noise is typically loudest during activities that involve excavation and soil movement, such as site preparation and grading. Project construction would occur nearest to the single-family residences located west and south of the project site. It is conservatively assumed that over the course of a typical construction day the construction equipment would operate 100 feet from the Maison’s Palmdale Boulevard 150, LLC

Operation Noise
The City of Palmdale has not established operational noise standards. Therefore, operational noise standards based upon USEPA are provided for this analysis. Based upon available sleep criteria data, an interior nighttime level of 35 dBA is considered acceƉƚĂďůĞ;h^ WϭϵϳϰͿ͘ƐƐƵŵŝŶŐĂ15 dBA

It is assumed that 191 ground-level HVAC units distributed across the project site would be needed, based on 191 dwelling units. The closest future residential lots to nearby receivers would occur on the southern edge of the project site.
Each residence would have at least one ground-level HVAC equipment. Given estimated setbacks, HVAC equipment could be within 20 feet of existing residences. At a distance of 20 feet, an HVAC unit would generate noise levels of 48 dBA, which would not exceed an exterior noise level of 50 dBA L
eq at nearby residences that would result in an exceedance of an acceptable interior noise environment of 35 dBA. In addition, future fencing between properties may provide additional noise attenuation. Therefore, operational noise impacts associated with HVAC equipment would be less than significant.
Additional on-site noise sources such as landscape maintenance, low-speed traffic on internal roadways, conversations, open space activities, and trash hauling also would be typical of noise generated by neighboring land uses and would not substantially contribute to overall ambient noise levels. Therefore, on-site operations would have a less than significant impact on noise-sensitive receivers.
Off-site Traffic Noise
The overall increase in traffic noise from the project was estimated using ADT “future with project conditions” data from the Traffic Signal Warrant Study prepared by General Technologies and Solutions, included as Appendix G. These daily ADT scenarios are shown in Table 19. The roadway segment that is expected to experience the greatest increase in trips is Palmdale Boulevard during PM peak hours. Therefore, it is anticipated that traffic at this roadway segment is expected to create the greatest off-site traffic noise impacts when compared to other intersections near the project site. As shown in Table 19, PM peak hour trips would increase by approximately nine percent over existing conditions under the project. A nine percent increase in traffic on a roadway would equate to an increase of 0.4 dBA. Therefore, the project would not double the existing mobile noise source Environmental Checklist

b. Would the project result in generation of excessive groundborne vibration or groundborne noise levels?
The project would result in the generation of excessive groundborne vibration or groundborne noise levels if vibration levels exceed 0.2 in/sec PPV at residential structures or 0.3 in/sec PPV at commercial structures.
The project does not include any substantial vibration sources associated with operation. Thus, construction activities have the greatest potential to generate ground-borne vibration affecting nearby receivers, especially during grading and excavation of the project site. Table 20 shows vibration levels of anticipated grading and excavation equipment used during construction. The greatest vibratory source during construction in the project vicinity would be a large bulldozer.
Neither blasting nor pile driving would be required for construction of the project.

Construction activities known to generate excessive ground-borne vibration, such as pile driving, would not be conducted to construct the project. Based on FTA recommendations, limiting vibration levels to below 0.2 in/sec PPV at residential structures would prevent architectural damage regardless of building construction type. The greatest anticipated source of vibration during project construction activities would be from a dozer, which may be used within 15 feet of the nearest off- site sensitive receivers to the to the west and south.

The proposed project could result in the addition of approximately 588 new residents in the city, which would bring the city’s population to 167,986, indicating that the city would need additional parkland to meet the current parkland to resident ratio.
The nearest park to the project is Domenic Massari Park, located approximately 3,500 feet south of the project site, which is a 40-acre park that includes a playground area, two picnic pavilions, walking and jogging paths, five soccer fields, and other amenities. Residents under the proposed project may use the existing recreational facilities, which could result in deterioration or need for additional recreational space. The project would provide a pocket community park, a children’s play area, and additional community open spaces. Additionally, a community trail network is planned to link the neighborhood and provide additional open spaces and parks for the community to utilize.

The project site is in an urban area already served by public services and facilities, such as utilities and public libraries. Development of the project would result in incremental impacts to the City’s public services and facilities such as storm drain usage, solid-waste disposal, water usage, and wastewater disposal. These impacts are analyzed in Section 10, Hydrology and Water Quality, and Section 19, Utilities and Service Systems. The project’s contribution to storm drain usage, solid- waste disposal, water usage, and wastewater disposal would be offset through project-specific features described in the individual resource section analyses indicated above.

The City of Palmdale is served by the Palmdale City Library located approximately 4.5 miles east of the project site at 700 East Palmdale Boulevard. As discussed in Section 14, Population and Housing, the proposed project could potentially increase the city’s population by up to 588 residents, which would be an increase of approximately 0.35 percent of the city’s population. Increased population generated by the proposed project would incrementally increase demand on local public libraries in the vicinity, such as the Palmdale City Library. However, the project would be subject to Palmdale’s development impact fees for library facilities. As a result, the proposed project would contribute to the financing of library services through impact fees and property taxes, which would mitigate the need for new or physically altered government facilities that support library use. Therefore, the project would not substantially affect existing governmental facilities or require the need for new or altered governmental facilities. Impacts would be less than significant.

commercial/retail amenities, which would reduce the
number of trips and VMT. In conclusion, the project would be consistent with Goal C2.
General Plan Land Use and Community Design Element
Goal L1: Create a vision for long-term growth and
development in the City of Palmdale which provides for
orderly, functional patterns of land uses within urban
areas, a unified and coherent urban form, and a high
quality of life for its residents.
Policy L1.1.1: Through adoption of the Land Use Map,
direct future growth to areas which can accommodate
development based upon topography, environmental
factors, availability of infrastructure, and/or

b. Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)?
In December 2018, the California Natural Resources Agency certified and adopted the updated CEQA Guidelines package. The amended CEQA Guidelines, specifically Section 15064.3, generally require the use of VMT as the primary metric for the evaluation of transportation impacts associated with land use and transportation projects. In general terms, VMT quantifies the amount and distance of automobile travel attributable to a project or region. All agencies and projects state- wide are required to utilize the updated CEQA Guidelines for evaluating transportation impacts as of July 1, 2020.
The updated CEQA Guidelines allow for the lead agency to have discretion in establishing methodologies and thresholds, provided there is substantial evidence to demonstrate that the established procedures promote the intended goals of the legislation. Where quantitative models or methods are unavailable, CEQA Guidelines Section 15064.3 allows agencies to assess VMT qualitatively using factors such as availability of transit and proximity to other destinations. The KĨĨŝĐĞŽĨWůĂŶŶŝŶŐĂŶĚZĞƐĞĂƌĐŚ;KWZͿTechnical Advisory on Evaluating Transportation Impacts in CEQA provides technical considerations regarding methodologies and thresholds with a focus on office, residential, and retail developments as these projects tend to have the greatest influence on VMT.

Pursuant to the Los Angeles County Public Works TIA Guidelines, certain residential projects that further the State’s affordable housing goals are presumed to have a less-than-significant impact on VMT if 100 percent of the units, excluding manager’s units, are set aside for lower income households. Based on the screening criteria above, the project is a 100 percent affordable project and therefore VMT impacts would be less than significant.

Prior to construction, site circulation plans would be reviewed by the LACoFD during the project application process to ensure adequate on-site lane widths and configurations for emergency vehicle ingress and egress. Furthermore, the proposed project would not modify existing roadways in the vicinity, other than by adding new site access points, and therefore, would not affect emergency vehicle use of roadways that surround the project site. The project would be subject to LACoFD review of site plans prior to occupancy to ensure that required fire protection safety features, including building sprinklers and emergency access, are implemented. During project operation, emergency response vehicles would be able to access the project site via the main entrance along East Palmdale Boulevard.

proposed project during the normal years. However, PWD anticipates that during a single-dry year conditions, demand will exceed existing supply starting in 2045. PWD anticipates demand exceeding supplies in 2021 and 2023 during a consecutive five-year drought. Additional supplies or a reduction in demand are needed to meet demand; therefore, PWD has identified short-term and long-term transfer and exchange opportunities to provide additional supplies to overcome shortages. In addition, PWD is developing the Palmdale Regional Water Augmentation Project to provide surface water augmentation or groundwater injection.

Therefore, the PWRP would have adequate capacity to provide wastewater treatment for the proposed project and the proposed project would not require the construction of new or expanded wastewater conveyance or treatment facilities. Potential impacts would be less than significant.
Stormwater
The project site would continue to connect to the existing storm drain system operated and maintained by the City. The proposed project would increase impervious surfaces over the project site due to the construction of 191 residential units. As discussed in Section 10, Hydrology and Water Quality, prior to the initiation of construction, the project would be required to obtain coverage under a Construction General Permit to comply with the NPDES requirement. In addition, the project would be required to comply with the LARWQCB’s Water Quality Control Plan. Under the conditions of the Construction General Permit and the Water Quality Control Plan, the developer would be required to eliminate or reduce non-storm water discharges, develop, and implement a SWPPP for the project construction activities, and perform inspections of the storm water pollution prevention measures and control practices to ensure conformance with the site SWPPP and associated BMPs. Therefore, stormwater facilities would be less than significant.

According to CalEEMod outputs in the Air Quality Greenhouse Gas Emissions Study ;ƉƉĞŶĚŝdžAͿ͕ there would be no estimated natural gas consumption for the project. Therefore, the project would not require additional natural gas storage/transmission facilities. Likewise, the project site is an infill project served by existing telecommunications facilities within the city and would not require the expansion or construction of new telecommunications infrastructure. Telecommunications including cell phone towers, microwave towers, and other telecommunication equipment are located throughout the city. According to the City of Palmdale General Plan, cell phone, fiber optic, and microwave towers are owned by AT&T, CenturyLink, DirectTV, Dish Network, Exede Satellite Internet, Frontier Communications, HughesNet, Sprint, Time Warner, Verizon, and Viasat Satellite.

b. Would the project have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? The project site receives its water service from the PWD with water supplies that include imported water, local and regional supplies, groundwater, and recycled water. PWD purchases imported water from the Department of Water Resources. The groundwater used by PWD is pumped from the Antelope Valley Groundwater Basin and has accounted for 35 percent of PWD’s supplies since 2016. PWD jointly owns and operates the Littlerock Dam Reservoir, which constitutes PWD’s surface water supply source and is located in the hills southwest of the PWD service area.

The last reported remaining capacity at the landfill was approximately 17,911,225 ĐƵďŝĐLJĂƌĚƐ;ĂůZĞĐLJĐůĞϮϬϭϵͿ͘ Construction of the proposed project would generate solid waste, including construction debris. This construction debris would include materials such as scrap wood, concrete, and plaster materials.
Construction debris would be removed and disposed of in a timely manner and in accordance with all applicable laws and regulations. The handling of all debris and waste generated during construction of the project would be subject to CALGreen requirements and the California Integrated Waste Management Act of 1989 ; ϵϯϵͿƌĞƋƵŝƌĞŵĞŶƚƐĨŽƌƐĂůǀĂŐŝŶŐ͕ƌĞĐLJĐůŝŶŐ͕ĂŶĚ reuse of materials from construction activity on the project site.

As discussed in Section 4, Biological Resources, the project site contains suitable habitat for western Joshua tree and short-joint beavertail cactus as well as California glossy snake, coast horned lizard, burrowing owl, loggerhead shrike, LeConte’s thrasher, and nesting birds. Implementation of Mitigation Measures BIO-1 through BIO-6 would address potential impacts to special-status species and natural habitats occurring in the project site. Mitigation Measures BIO-1 and BIO-2 would reduce impacts to western Joshua trees to less than significant and further reduce impacts to short- joint beavertail cacti.

Implementation of Mitigation Measures BIO-1, and BIO-5 would reduce impacts to these species to a less than significant level, and would also require compliance with federal and State law by avoiding take of nesting birds. The site is a suitable habitat for the Desert kit fox, thus Mitigation Measure BIO-5 requires compliance with CDFW regulations.
As discussed in Section 5, Cultural Resources, the Cultural Resources Study reported that no eligible historical or archeological resources are located on the project site. However, the project site has the potential to yield unknown archeological resources. As a result, it is recommended than an archeological monitor be present during future ground disturbances associated with the project to observe grading and identify any historic or prehistoric resources that may be discovered during the construction period. Implementation of Mitigation Measure CR-1 would avoid or reduce the project’s potentially significant impacts to any archaeological resources that may be found during ground disturbing activities.
Impacts would be less than significant with the mitigation incorporated; therefore, the project would not substantially degrade the quality of the environment due to impacts associated with biological and cultural resources.

Therefore, the proposed project would not be anticipated to create a cumulatively considerable noise impact.
As discussed in Section 17, Transportation, the project would not conflict with any City policies addressing the circulation network and would not generate substantial VMT. Therefore, the project would not contribute to any cumulatively considerable adverse transportation effects.

LESS THAN SIGNIFICANT IMPACT
c. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?
In general, impacts to human beings are associated with air quality, GHG emissions and climate change, hazards and hazardous materials, and noise impacts. As detailed in analyses for air quality, hazards and hazardous materials, and noise, the proposed project would not result, either directly or indirectly, in adverse effects related to these issue areas. In the case of GHG emissions, operations of the proposed project would generate GHG emissions that would exceed the 2.0 MT of CO
2e per year per service person goal of the City CAP, and impacts would be potentially significant.
As discussed in Section 8 Greenhouse Gas Emissions, implementation of Mitigation Measure GHG-1 would require the project applicant to ƉƌĞƉĂƌĞĂŶĚŝŵƉůĞŵĞŶƚĂ','ZĞĚƵĐƚŝŽŶWůĂŶ;','ZWͿƚŚĂƚ demonstrates emissions reductions from project operation by approximately 730 MT of CO2e per year to 1,198 MT of CO2e per year for the lifetime of the project, or by an amount determined through further analysis of project GHG emissions at the time of GHGRP preparation in order to reduce impacts to a less than significant level. Compliance with applicable rules and regulations included in this IS-MND would reduce potential impacts on human beings to a less than significant level.

Project Description and Impact Summary
Air Quality and Greenhouse Gas Emissions Study 1
1 Project Descriptio n and Impact Summary
Introduction
This report details the analysis of potential air quality and greenhouse gas (GHG) impacts associated with the construction and operation of the proposed Tentative Tract Map (TTM) 83359 Project (herein referred to as “proposed project” or “project”) in Palmdale, California. Rincon Consultants, Inc. (Rincon) prepared this study under contract to Maison’s Palmdale Boulevard 150, LLC for use by the City of Palmdale in support of environmental documentation being prepared for the project pursuant to the California Environmental Quality Act (CEQA).
Project Summary
Project Location
The project site is in the City of Palmdale in northern Los Angeles County in southern California. The regional location of the project site is shown in Figure 1. The 20-acre project site (Assessor’s Parcel Number 3023-002-184) is located immediately adjacent to, and south of, East Palmdale Boulevard between 55th Street and 50th Street East. The project location is depicted in Figure 2. Surrounding land uses include single family residential uses to the south, east, and west. The vacant parcel of property immediately to the north of the project site across Palmdale Boulevard has an existing land use designation of Business Park and is zoned as Planned Industrial (M-4).
Project Description
The proposed project would facilitate the development of up to 191 units of single story, single- family homes consisting of three-bedroom housing units, two-bedroom Accessory Dwelling Units and one-bedroom Junior Accessory Dwelling Units that would be offered for rent as a 100% affordable project to those qualifying at 30% to 80% Area Mean Income (AMI) for Los Angeles County. The project would also include a recreation center and community amenities on a total of 66 lots. The community would be all-electric and each residential unit would be constructed with rooftop solar, energy efficient appliances, and installation of all infrastructure improvements as conditioned by the City of Palmdale with approval of Tentative Tract Map (TTM) 83359. Within each lot, primary homes, accessory dwelling units (ADU), and junior ADUs would be linked together by a network of walking paths and trails.
Indoor community amenities include a community building with a tenant lounge, office spaces, and a fitness center. Outdoor amenities include a pool, spa, grill area, pocket community park, children’s play area, and additional community open spaces. Additionally, a community trail network is planned to link the neighborhood and provide for additional open spaces and parks for the community to utilize.
Streets that would be constructed within the project site and would link the community to East Palmdale Boulevard to the north as well as the existing residential projects to both the east and west of the project. All public right-of-way would be constructed to the width shown on the TTM and would include road, sidewalks, and curbs and gutters. ADA curb ramps, appropriate street signage, fire hydrants, and streetlights would also be installed for each street both inside and outside of the development.

Air Quality
Local Climate and Meteorology
The project site is within the Mojave Desert Air Basin (MDAB), an inland region in southern California includes the desert portions of northwestern Los Angeles County, eastern Kern County, northeastern Riverside County, and San Bernardino County. The region is closed off from southern coast of California and central California by mountain ranges with the Sierra Nevada Mountains to the north, the Tehachapi Mountains to the northwest and the San Gabriel and San Bernardino Mountains to the south. The Sonoran Desert borders the eastern and southern portions of the MDAB. The regional climate in the MDAB is dry-host desert climate characterized by little cloud formation, daytime solar heating, and infrequent precipitation. The air quality within the MDAB is primarily influenced by meteorology, topography, and a wide range of emission sources, such as dense population centers, substantial vehicular traffic, and industry. The Antelope Valley Air Quality Management District (AVAQMD) monitors and regulates local air quality in the eastern portion of the MDAB, which includes the cities of Lancaster and Palmdale (AVAQMD 2022a).
Air Quality Regulations
Federal Air Quality Regulations
Ambient Air Quality Standards represent the maximum levels of background pollution considered safe, with an adequate margin of safety, to protect the public health and welfare. The federal Clean Air Act (CAA) was enacted in 1970 and amended in 1977 and 1990 [42 United States Code (USC) 7401] for the purposes of protecting and enhancing the quality of the nation’s air resources to benefit public health, welfare, and productivity.
The U.S. Environmental Protection Agency (USEPA) has set primary and secondary National Ambient Air Quality Standards (NAAQS) for ozone, carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter with a diameter of up to ten microns (PM10) and up to
2.5 microns (PM2.5), and lead (Pb). Primary standards are those levels of air quality deemed necessary, with an adequate margin of safety, to protect public health. Table 1 lists the current federal and state standards for regulated pollutants.

State Air Quality Regulations
CALIFORNIA AMBIENT AIR QUALITY STANDARDS
The California Clean Air Act (CCAA) was enacted in 1988 (California Health & Safety Code (H&SC) Section 39000 et seq.). While USEPA is the federal agency designated to administer air quality regulation, the California Air Resources Board (CARB) is the State equivalent in the California Environmental Protection Agency (CalEPA). Under the CCAA the State has developed the California Ambient Air Quality Standards (CAAQS), which are generally more stringent than the NAAQS.
Table 1 lists the current State standards for regulated pollutants. In addition to the federal criteria pollutants, the CAAQS also specify standards for visibility-reducing particles, sulfates, hydrogen sulfide, and vinyl chloride. Like the federal CAA, the CCAA classifies specific geographic areas as either “attainment” or “nonattainment” areas for each pollutant, based on the comparison of measured data within the CAAQS.
California is divided geographically into 15 air basins for managing the air resources of the State on a regional basis. Areas within each air basin are considered to share the same air masses and, therefore, are expected to have similar ambient air quality. If an air basin is not in either federal or State attainment for a criteria pollutant, the basin is classified as a nonattainment area for that pollutant. Under the CAA, once a nonattainment area has achieved the air quality standards for a criteria pollutant, it may be re-designated to an attainment area for that pollutant. To be re- designated, the area must meet air quality standards and have a 10-year plan for continuing to meet and maintain air quality standards, as well as satisfy other requirements of the federal CAA.
Areas that have been re-designated to attainment are called maintenance areas.
The MDAB is designated a nonattainment area for the federal and State eight-hour ozone standards, State one-hour ozone standards, and for State PM10 standards. The AVAQMD portion of the MDAB is designated unclassifiable or in attainment for all other federal and State standards (AVAQMD 2022b).

OXIC AIR CONTAMINANTS
A toxic air contaminant (TAC) is an air pollutant that may cause or contribute to an increase in mortality or serious illness or which may pose a present or potential hazard to human health. TACs Maison’s Palmdale Boulevard 150, LLC
Tentative Tract Map 83359 Project
8 may result in long-term health effects such as cancer, birth defects, neurological damage, asthma, or genetic damage, or short-term acute effects such as eye watering, respiratory irritation, runny nose, throat pain, and headaches. TACs are considered either carcinogenic or non-carcinogenic based on the nature of the health effects associated with exposure. For carcinogenic TACs, potential health impacts are evaluated in terms of overall relative risk expressed as excess cancer cases per one million exposed individuals. Non-carcinogenic 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.
TACs include both organic and inorganic chemical substances. One of the main sources of TACs in California is diesel engines that emit exhaust containing solid material known as diesel particulate matter (DPM); however, TACs may be emitted from a variety of common sources, including gasoline stations, motor vehicles, dry cleaners, industrial operations, painting operations, and research and teaching facilities. TACs commonly associated with gasoline dispensing stations include the organic compounds of benzene, toluene, and xylene. Benzene is a known human carcinogen and can result in short-term acute and long-term chronic health impacts (USEPA n.d.).
In 1983, the California Legislature enacted a program to identify the health effects of TACs and to reduce exposure to these contaminants to protect the public health (Assembly Bill [AB] 1807:
Health and Safety Code Sections 39650–39674). The Legislature established a two-step process to address the potential health effects from TACs. The first step is the risk assessment (or identification) phase. The second step is the risk management (or control) phase of the process.
The California Air Toxics Program establishes the process for the identification and control of TACs and includes provisions to make the public aware of significant toxic exposures and for reducing risk. Additionally, the Air Toxics "Hot Spots" Information and Assessment Act (AB 2588, 1987, Connelly Bill) was enacted in 1987 and requires stationary sources to report the types and quantities of certain substances routinely released into the air. The goals of the Air Toxics "Hot Spots" Act are to collect emission data, identify facilities having localized impacts, ascertain health risks, notify nearby residents of significant risks, and reduce those significant risks to acceptable levels. The Children's Environmental Health Protection Act, California Senate Bill 25 (Chapter 731, Escutia, Statutes of 1999), focuses on children's exposure to air pollutants. The act requires CARB to review its air quality standards from a children's health perspective, evaluate the statewide air quality monitoring network, and develop any additional air toxic control measures needed to protect children's health.
S
TATE IMPLEMENTATION PLAN
The federal CAA Amendments mandate that states submit and implement a State Implementation Plan (SIP) for areas not meeting air quality standards. The SIP includes pollution control measures to demonstrate how the standards will be met through those measures. The SIP is established by incorporating measures established during the preparation of air quality attainment plans and adopted rules and regulations by each local air district, which are submitted for approval to CARB and the USEPA. The goal of an air quality attainment plan is to reduce pollutant concentrations below the NAAQS through the implementation of air pollutant emissions controls. Local air districts and other agencies, such as the Department of Pesticide Regulation and the Bureau of Automotive Repair, prepare SIP elements and submit them to CARB for review and approval. CARB then forwards SIP revisions to the USEPA for approval and publication in the Federal Register. All of the items included in the California SIP are listed in the Code of Federal Regulations (CFR) at 40 CFR 52.220.
Background
Air Quality and Greenhouse Gas Emissions Study 9
As the regional air quality management district, the AVAQMD is responsible for preparing and implementing the portion of the SIP applicable to the portion of the MDAB within its jurisdiction.
The air pollution control district for each county adopts rules, regulations, and programs to attain federal and state air quality standards and appropriates money (including permit fees) to achieve these objectives.
Local Air Quality Regulations
AVAQMD
OZONE ATTAINMENT PLAN
Under state law, air districts are required to prepare a plan for air quality improvement for pollutants for which the district is in non-compliance. The AVAQMD adopted the Federal 75 parts per billion (ppb) Ozone Attainment Plan for the Western Mojave Desert Nonattainment Area in March 2017 to reach attainment for federal and State standards. The Ozone Attainment Plan incorporates new scientific data and notable regulatory actions that have occurred since adoption of the 2010 Ozone Attainment Plan including the approval of the new federal 8-hour ozone standard of 0.070 parts per million (ppm) that was finalized in 2015. The Final 2017 Ozone Attainment Plan addresses several State and federal planning requirements and incorporates new scientific information, primarily in the form of updated emissions inventories, ambient measurements, and meteorological air quality models. The Southern California Association of Governments’ (SCAG) projections for socio-economic data (e.g., population, housing, employment by industry) and transportation activities from the 2016 Regional Transportation Plan/Sustainable Communities Strategy (2016 RTP/SCS) are integrated into the 2017 Ozone Attainment Plan. To minimize potential impacts from project emissions, the AVAQMD implements rules and regulations for emissions that may be generated by various uses and activities. Rules and regulations relevant to the proposed project include Rule 403 (Fugitive Dust), Rule 402 (Nuisance), and Rule 1113 (Architectural Coatings).
2020-2045
REGIONAL TRANSPORTATION PLAN/SUSTAINABLE COMMUNITIES STRATEGY SCAG is the regional planning agency for Los Angeles, Orange, Ventura, Riverside, San Bernardino, and Imperial Counties. On September 3, 2020, SCAG’s Regional Council formally adopted the 2020- 2045 RTP/SCS (titled Connect SoCal). The 2020-2045 RTP/SCS builds upon the progress made through implementation of the 2016-2040 RTP/SCS and includes 10 goals focused on promoting economic prosperity, improving mobility, protecting the environment, and supporting healthy/complete communities. The SCS implementation strategies include focusing growth near destinations and mobility options, promoting diverse housing choices, leveraging technology innovations, and supporting implementation of sustainability policies. The SCS establishes a land use vision of center-focused placemaking, concentrating growth in and near Priority Growth Areas, transferring of development rights, urban greening, creating greenbelts and community separators, and implementing regional advance mitigation (SCAG 2020). The RTP/SCS pertains to air quality because the strategies set forth in the plan would reduce air pollutant emissions from mobile sources.

10 and sustainability. The General Plan includes numerous goals and policies in the Air Quality Element through which air quality would be improved and project impacts reduced, as follows:
Goal AQ-2: Minimize particulates less than 10 microns in size (PM10) and minimizes activities that generate dust.
à Policy AQ 2-4: Erosion and Dust Control Measures. Require erosion and dust control measures for new construction, including covering soil with straw mats or use of chemical soil and dust binders during site grading, followed by hydroseeding and watering disturbed construction areas as soon as possible after grading to prevent fugitive dust. Goal AQ-3: Reduction and/or elimination of unnecessary sources of air pollution. à Policy AQ 3-4: Reduce Reactive Organic Gas. Reduce reactive organic gas (ROG) and particulate emissions from building materials and construction methods, by promoting the use of nonsolvent-based, high-solid, or water-based coatings, and requiring compliance with all pertinent AVAQMD rules.
Goal AQ-4: Reduce air pollution caused by energy consumption. à Policy AQ 4-2: Energy Conservation. Encourage energy conservation from all sectors of the community by promoting and/or requiring the use of energy efficient appliances, processes, and equipment, and promoting energy audits and retrofits of existing structures.
à Policy AQ 4-3: Recycling. Require local government, Palmdale citizens, and local businesses and industries to recycle, as mandated by state law, and to otherwise recycle to the maximum extent possible in accordance with the requirements of the Palmdale Municipal Code.
à Policy AQ 4-4: Solar Energy. Require new developments to minimize obstruction of direct sunlight for solar energy systems on adjacent properties.
Criteria Pollutants
Ozone
Ozone is produced by a photochemical reaction (triggered by sunlight) between nitrogen oxides (NOX) and reactive organic gases1 (ROG). NOX are formed during the combustion of fuels, while ROG are formed during combustion and evaporation of organic solvents. Because ozone requires sunlight to form, it usually occurs in substantial concentrations between the months of April and October. Ozone is a pungent, colorless, toxic gas with direct health effects on humans including respiratory and eye irritation and possible changes in lung functions. Groups most sensitive to ozone include children, the elderly, people with respiratory disorders, and people who exercise strenuously outdoors.
1 Organic compound precursors of ozone are routinely described by several variations of three terms: hydrocarbons (HC), organic gases (OG), and organic compounds (OC). These terms are often modified by adjectives such as total, reactive, or volatile, and result in various acronyms, such as TOG (total organic gases), ROG (reactive organic gases), ROC (reactive organic compounds), and VOC (volatile organic compounds). While most of these differ in some significant way from a chemical perspective, two groups are important from an air quality perspective: non-photochemically reactive in the lower atmosphere, or photochemically reactive in the lower atmosphere (ROG and VOC).
Background
Air Quality and Greenhouse Gas Emissions Study 11
Carbon Monoxide
CO is a local pollutant produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood. The primary source of CO, a colorless, odorless, poisonous gas, is automobile traffic. Therefore, elevated concentrations are usually found near areas of high traffic volumes. The health effects from CO are related to its affinity for hemoglobin in the blood. At high concentrations, CO reduces the amount of oxygen in the blood, causing heart difficulty in people with chronic diseases, reduced lung capacity, and impaired mental abilities.
Sulfur Dioxide
SO
2 is a combustion product, with the primary source being power plants and heavy industries that use coal or oil as fuel. SO2 is also a product of diesel engine combustion. The health effects of SO2 include lung disease and breathing problems for people with asthma. SO2 in the atmosphere contributes to the formation of acid rain.
Nitrogen Dioxide
NO2 is a byproduct of fuel combustion, with the primary sources being motor vehicles and industrial boilers and furnaces. The principal form of NO2 produced by combustion is nitric oxide (NO), but NO reacts rapidly to form NO2, creating the mixture of NO and NO2 commonly called NOX.
NO2 is an acute irritant. A relationship between NO2 and chronic pulmonary fibrosis may exist, and an increase in bronchitis in young children at concentrations below 0.3 parts per million (ppm) may occur. NO2 absorbs blue light, gives a reddish-brown cast to the atmosphere, and reduces visibility.
It can also contribute to the formation of ozone/smog and acid rain.
Particulate Matter
Suspended atmospheric PM10 and PM2.5 are comprised of finely divided solids and liquids such as dust, soot, aerosols, fumes, and mists. The characteristics, sources, and potential health effects associated with PM
10 and PM2.5 can be different. Major man-made sources of PM10 are agricultural operations, industrial processes, combustion of fossil fuels, construction, demolition operations, and entrainment of road dust into the atmosphere. Natural sources include windblown dust, wildfire smoke, and sea spray salt. The finer PM2.5 particulates are generally associated with combustion processes as well as formation in the atmosphere as a secondary pollutant through chemical reactions. PM2.5 is more likely to penetrate deeply into the lungs and poses a serious health threat to all groups, but particularly to the elderly, children, and those with respiratory problems. More than half of the PM2.5 that is inhaled into the lungs remains there, which can cause permanent lung damage. These materials can damage health by interfering with the body’s mechanisms for clearing the respiratory tract or by acting as carriers of an absorbed toxic substance.
Current Air Quality
CARB operates a network of air quality monitoring stations throughout the MDAB. The purpose of the monitoring stations is to measure ambient concentrations of pollutants and determine whether ambient air quality meets the California and federal standards. The monitoring station located closest to the project site is the Lancaster – 43301 Division Street station located approximately eight miles northwest of the project site. This monitoring station measures ozone, NO
2, PM10, and PM2.5.

The area also exceeded the State 1-hour ozone standard in 2020 and 2022 and the Federal PM 10 and PM2.5 standards in 2020 and 2021. The area did not exceed other air quality standards in 2020, 2021, or 2022.

Sensitive Receptors
The term “sensitive receptor” refers to a person in the population who is more susceptible to health effects due to exposure to an air contaminant than the population at large or to a land use that may reasonably be associated with such a person. Examples include residences, schools, playgrounds, childcare centers, churches, athletic facilities, retirement homes, and long-term health care facilities. Sensitive receptors that may be affected by air quality impacts associated with construction and operation of the proposed project include the residents of the single-family developments located adjacent to the western, southern, and eastern project boundaries, and single-family residences located 800 feet to north of the project site. There are no other sensitive receptor groups within 1,000 feet of the project site.
Greenhouse Gases
Climate change is the observed increase in the average temperature of the Earth’s atmosphere and oceans along with other substantial changes in climate (such as wind patterns, precipitation, and storms) over an extended period. The term “climate change” is often used interchangeably with Background
Air Quality and Greenhouse Gas Emissions Study 13
the term “global warming,” but climate change is preferred because it conveys that other changes are happening in addition to rising temperatures. The baseline against which these changes are measured originates in historical records that identify temperature changes that occurred in the past, such as during previous ice ages. The global climate is changing continuously, as evidenced in the geologic record which indicates repeated episodes of substantial warming and cooling. The rate of change has typically been incremental, with warming or cooling trends occurring over the course of thousands of years. The past 10,000 years have been marked by a period of incremental warming, as glaciers have steadily retreated across the globe. However, scientists have observed acceleration in the rate of warming over the past 150 years. The United Nations Intergovernmental Panel on Climate Change (IPCC) expressed that the rise and continued growth of atmospheric CO 2 concentrations is unequivocally due to human activities in the IPCC’s Sixth Assessment Report (2021). Human influence has warmed the atmosphere, ocean, and land, which has led the climate to warm at an unprecedented rate in the last 2,000 years. It is estimated that between the period of 1850 through 2019, that a total of 2,390 gigatonnes of anthropogenic CO 2 was emitted. It is
likely that anthropogenic activities have increased the global surface temperature by approximately 1.07 degrees Celsius between the years 2010 through 2019 (IPCC 2021).
Furthermore, since the late 1700s, estimated concentrations of CO 2, methane, and nitrous oxide in
the atmosphere have increased by over 43 percent, 156 percent, and 17 percent, respectively, primarily due to human activity (USEPA 2021a). Emissions resulting from human activities are thereby contributing to an average increase in Earth’s temperature.
Gases that absorb and re-emit infrared radiation in the atmosphere are called GHGs. The gases that are widely seen as the principal contributors to human-induced climate change include carbon dioxide (CO
2), methane (CH4), nitrous oxides (N2O), fluorinated gases such as hydrofluorocarbons and perfluorocarbons and sulfur hexafluoride (SF6). Water vapor is excluded from the list of GHGs because it is short-lived in the atmosphere, and its atmospheric concentrations are largely determined by natural processes, such as oceanic evaporation.
GHGs are emitted by natural processes and human activities. Of these gases, CO2 and CH4 are emitted in the greatest quantities from human activities. Emissions of CO2 are usually by-products of fossil fuel combustion, and CH4 results from off-gassing associated with agricultural practices and landfills. Human-made GHGs, many of which have greater heat-absorption potential than CO2, include fluorinated gases and SF6 (USEPA 2021a).
Different types of GHGs have varying global warming potentials (GWP). The GWP of a GHG is the potential of a gas or aerosol to trap heat in the atmosphere over a specified timescale (generally, 100 years). Because GHGs absorb different amounts of heat, a common reference gas (CO2) is used to relate the amount of heat absorbed to the amount of the gas emitted, referred to as “carbon dioxide equivalent” (CO2e), which is the amount of GHG emitted multiplied by its GWP. Carbon dioxide has a 100-year GWP of one. By contrast, methane has a GWP of 30, meaning its global warming effect is 30 times greater than CO2 on a molecule per molecule basis (IPCC 2021).2 The accumulation of GHGs in the atmosphere regulates the earth’s temperature. Without the natural heat-trapping effect of GHGs, the earth’s surface would be about 33 degrees Celsius (°C) cooler (World Meteorological Organization 2021). However, since 1750, estimated concentrations of CO2, CH4, and N2O in the atmosphere have increased by 47 percent, 156 percent, and 23
2 The Intergovernmental Panel on Climate Change’s (2021) Sixth Assessment Report determined that methane has a GWP of 30.
However, the 2017 Climate Change Scoping Plan published by the California Air Resources Board uses a GWP of 25 for methane, consistent with the Intergovernmental Panel on Climate Change’s (2007) Fourth Assessment Report. Therefore, this analysis utilizes a GWP of 25.

14 percent, respectively, primarily due to human activity (IPCC 2021). GHG emissions from human activities, particularly the consumption of fossil fuels for electricity production and transportation, are believed to have elevated the concentration of these gases in the atmosphere beyond the level of concentrations that occur naturally.
Greenhouse Gas Emissions Inventory
Global
In 2015, worldwide anthropogenic total 47,000 million MT of CO2e, which is a 43 percent increase from 1990 GHG levels (USEPA 2021b). Specifically, 34,522 million metric tons (MMT) of CO2e of CO2, 8,241 MMT of CO2e of CH4, 2,997 MMT of CO2e of N2O, and 1,001 MMT of CO2e of fluorinated gases were emitted in 2015. The largest source of GHG emissions were energy 14production and use (includes fuels used by vehicles and buildings), which accounted for 75 percent of the global GHG emissions. Agriculture uses and industrial processes contributed 12 percent and six percent, respectively. Waste sources contributed for three percent and two percent was due to international transportation sources. These sources account for approximately 98 percent because there was a net sink of two percent from land-use change and forestry. (USEPA 2021b).
Federal
United States GHG emissions were 6,347.7 MMT of CO
2e in 2021 or 5,593.5 MMT CO2e after
accounting for sequestration. Emissions increased by 6.8 percent from 2020 to 2021. The increase from 2020 to 2021 was driven by an increase in CO
2 emissions from fossil fuel combustion which
increased seven percent relative to previous years and is primarily due to the economic rebounding after the COVID-19 Pandemic. In 2020, the energy sector (including transportation) accounted for 81 percent of nationwide GHG emissions while agriculture, industrial and waste accounted for approximately 10 percent, six percent, and three percent respectively (USEPA 2023).
California
Based on a review of the California Air Resource Board (CARB) California Greenhouse Gas Inventory for the years between 2000-2020, California produced 369.2 MMT of CO2e in 2020, which is
35.3 MMT of CO2e lower than 2019 levels. The 2019 to 2020 decrease in emissions is likely due in large part to the impacts of the COVID-19 pandemic. The major source of GHG emissions in California is the transportation sector, which comprises 37 percent of the State’s total GHG emissions. The industrial sector is the second largest source, comprising 20 percent of the State’s GHG emissions while electric power accounts for approximately 16 percent. The magnitude of California’s total GHG emissions is due in part to its large size and large population compared to other states. However, a factor that reduces California’s per capita fuel use and GHG emissions as compared to other states is its relatively mild climate. In 2016, California achieved its 2020 GHG emission reduction target of reducing emissions to 1990 levels as emissions fell below 431 MMT of CO
2e (CARB 2022). The annual 2030 statewide target emissions level is 260 MMT of CO2e (CARB 2017).
Regional
The City of Palmdale’ Climate Action Plan (CAP) includes GHG inventories for the City (City of Palmdale 2022). In 2017, total community GHG emissions were estimated at 1,042,284 MT CO2e.
Out of the total 2017 GHG emissions inventory, on-road transportation (i.e., gasoline and diesel Background
Air Quality and Greenhouse Gas Emissions Study 15
consumption from motor vehicles on local roads and highways) accounted for 59 percent of the emissions, residential energy consumption accounted for 19 percent, and nonresidential energy consumption accounted for 16 percent. The remaining six percent of GHG emissions was due to solid waste, off-road equipment, water and wastewater, and industrial sources.
Potential Effects of Climate Change
Globally, climate change has the potential to affect numerous environmental resources through potential impacts related to future air temperatures and precipitation patterns. Scientific modeling predicts that continued GHG emissions at or above current rates would induce more extreme climate changes during the 21
st century than were observed during the 20th century. Long-term trends have found that each of the past three decades has been warmer than all the previous decades in the instrumental record, and the decade from 2000 through 2010 has been the warmest. The observed global mean surface temperature for the decade from 2006 to 2015 was approximately 0.87°C (0.75°C to 0.99°C) higher than the global mean surface temperature over the period from 1850 to 1900. Furthermore, several independently analyzed data records of global and regional Land-Surface Air Temperature (LSAT) obtained from station observations agree that LSAT as well as sea surface temperatures have increased. Due to past and current activities, anthropogenic GHG emissions are increasing global mean surface temperature at a rate of 0.2°C per decade. In addition to these findings, there are identifiable signs that global warming is currently taking place, including substantial ice loss in the Arctic over the past two decades (IPCC 2021).
According to California’s Fourth Climate Change Assessment, statewide temperatures from 1986 to 2016 were approximately 1°F to 2°F higher than those recorded from 1901 to 1960. Potential impacts of climate change in California may include loss in water supply from snowpack, sea level rise, more extreme heat days per year, more large forest fires, and more drought years (State of California 2018). Below is a summary of some of the potential effects that could be experienced in California as a result of climate change.
Air Quality
Higher temperatures, which are conducive to air pollution formation, could worsen air quality in California. Climate change may increase the concentration of ground-level ozone, but the magnitude of the effect, and therefore its indirect effects, are uncertain. As temperatures have increased in recent years, the area burned by wildfires throughout the state has increased, and wildfires have been occurring at higher elevations in the Sierra Nevada Mountains (State of California 2018). If higher temperatures continue to be accompanied by an increase in the incidence and extent of large wildfires, air quality would worsen. However, if higher temperatures are accompanied by wetter, rather than drier conditions, the rains would tend to temporarily clear the air of particulate pollution and reduce the incidence of large wildfires, thereby improving the pollution associated with wildfires. Additionally, severe heat accompanied by drier conditions and poor air quality could increase the number of heat-related deaths, illnesses, and asthma attacks throughout the state (California Natural Resources Agency 2009).
Water Supply
Analysis of paleoclimatic data (such as tree-ring reconstructions of stream flow and precipitation) indicates a history of naturally and widely varying hydrologic conditions in California and the west, including a pattern of recurring and extended droughts. Uncertainty remains with respect to the Maison’s Palmdale Boulevard 150, LLC
Tentative Tract Map 83359 Project
16 overall impact of climate change on future precipitation trends and water supplies in California.
This uncertainty regarding future precipitation trends complicates the analysis of future water demand, especially where the relationship between climate change and its potential effect on water demand is not well understood. However, the average early spring snowpack in the western United States, including the Sierra Nevada Mountains, decreased by about 10 percent during the last century. During the same period, sea level rose over 5.9 inches along the central and southern California coast (State of California 2018). The Sierra snowpack provides most of California's water supply by accumulating snow during the state’s wet winters and releasing it slowly during the state’s dry springs and summers (April and July). The snowmelt currently provides an annual average of 15 million acre-feet of water each year, and it is predicted that the snowpack will be reduced by 25 to 40 percent compared to its historic average by 2050 (California Department of Water Resources 2013). Climate change will also result in less snowfall at lower elevations and reduce the total snowpack, resulting in less available water (California Department of Water Resources 2013). The State of California projects that average spring snowpack in the Sierra Nevada and other mountain catchments in central and northern California will decline by approximately 66 percent from its historical average by 2050 (State of California 2018).
Hydrology and Sea Level Rise
Climate change has the potential to induce substantial sea level rise in the coming century (State of California 2018). The rising sea level increases the likelihood and risk of flooding. The rate of increase of global mean sea levels over the 2001-2010 decade, as observed by satellites, ocean buoys and land gauges, was approximately 3.2 mm per year, which is double the observed 20th century trend of 1.6 mm per year (World Meteorological Organization [WMO] 2013). As a result, global mean sea levels averaged over the last decade were about 8 inches higher than those of 1880 (WMO 2013). Sea levels are rising faster now than in the previous two millennia and the rise is expected to accelerate, even with robust GHG emission control measures. The most recent IPCC report predicts a mean sea–level rise of 10 to 37 inches by 2100 (IPCC 2021). A rise in sea levels could completely erode 31 to 67 percent of southern California beaches, result in flooding of approximately 370 miles of coastal highways during 100-year storm events, jeopardize California’s water supply due to saltwater intrusion, and induce groundwater flooding and/or exposure of buried infrastructure (State of California 2018). In addition, increased CO 2 emissions can cause
oceans to acidify due to the carbonic acid it forms. Increased storm intensity and frequency could affect the ability of flood-control facilities, including levees, to handle storm events.
Agriculture
California has a $50 billion annual agricultural industry that produces over a third of the country’s vegetables and two-thirds of the country’s fruits and nuts (California Department of Food and Agriculture 2020). Higher CO2 levels can stimulate plant production and increase plant water-use efficiency. However, if temperatures rise and drier conditions prevail, certain regions of agricultural production could experience water shortages of up to 16 percent; water demand could increase as hotter conditions lead to the loss of soil moisture; crop-yield could be threatened by water-induced stress and extreme heat waves; and plants may be susceptible to new and changing pest and disease outbreaks (State of California 2018). In addition, temperature increases could change the time of year certain crops, such as wine grapes, bloom or ripen, and thereby affect their quality (California Climate Change Center 2006).
Background
Air Quality and Greenhouse Gas Emissions Study 17
Ecosystems and Wildlife
Climate change, and the potential resulting changes in weather patterns, could have ecological effects on a global and local scale. Increasing concentrations of GHGs are likely to accelerate the rate of climate change. Scientists project that the annual average maximum daily temperatures in California could rise by 4.4 to 5.8°F in the next 50 years and by 5.6 to 8.8°F in the next century (State of California 2018). Soil moisture is likely to decline in many regions, and intense rainstorms are likely to become more frequent. Rising temperatures could have four major impacts on plants and animals related to (1) timing of ecological events; (2) geographic distribution and range; (3) species’ composition and the incidence of nonnative species within communities; and (4) ecosystem processes, such as carbon cycling and storage (Parmesan 2006; State of California 2018). Increases in wildfire would further remove sensitive habitat; increased severity in droughts would potentially starve plants and animals of water; and sea level rise will affect sensitive coastal ecosystems.
Greenhouse Gas Regulations
Federal Regulations
The U.S. Supreme Court in Massachusetts et al. v. Environmental Protection Agency et al. ([2007] 549 U.S. 05-1120) held that the USEPA has the authority to regulate motor-vehicle GHG emissions under the federal Clean Air Act. The USEPA issued a Final Rule for mandatory reporting of GHG emissions in October 2009. This Final Rule applies to fossil fuel suppliers, industrial gas suppliers, direct GHG emitters, and manufacturers of heavy-duty and off-road vehicles and vehicle engines and requires annual reporting of emissions. In 2012, the USEPA issued a Final Rule that establishes the GHG permitting thresholds that determine when CAA permits under the New Source Review Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs are required for new and existing industrial facilities.
In 2014, the U.S. Supreme Court in Utility Air Regulatory Group v. EPA (134 S. Ct. 2427 [2014]) held that USEPA may not treat GHGs as an air pollutant for purposes of determining whether a source is a major source required to obtain a PSD or Title V permit. The Court also held that PSD permits that are otherwise required (based on emissions of other pollutants) may continue to require limitations on GHG emissions based on the application of Best Available Control Technology (BACT).
State Regulations
A
SSEMBLY BILL 1493 - CALIFORNIA ADVANCED CLEAN CARS PROGRAM AB 1493 (2002), California’s Advanced Clean Cars program (referred to as “Pavley”), requires CARB to develop and adopt regulations to achieve “the maximum feasible and cost-effective reduction of GHG emissions from motor vehicles.” On June 30, 2009, USEPA granted the waiver of CAA preemption to California for its GHG emission standards for motor vehicles beginning with the 2009 model year. Pavley I regulates model years from 2009 to 2016 and Pavley II, which is now referred to as “LEV (Low Emission Vehicle) III GHG” regulates model years from 2017 to 2025. The Advanced Clean Cars program coordinates the goals of the Low Emissions Vehicles (LEV), Zero Emissions Vehicles (ZEV), and Clean Fuels Outlet programs, and should provide major reductions in GHG emissions. By 2025, when the rules will be fully implemented, new automobiles will emit Maison’s Palmdale Boulevard 150, LLC

18 34 percent fewer GHGs and 75 percent fewer smog-forming emissions from their model year 2016 levels (CARB 2011).
CALIFORNIA GLOBAL WARMING SOLUTIONS ACT OF 2006 (ASSEMBLY BILL 32, AND SENATE BILL 32) The “California Global Warming Solutions Act of 2006,” (AB 32), outlines California’s major legislative initiative for reducing GHG emissions. AB 32 codifies the statewide goal of reducing GHG emissions to 1990 levels by 2020 and requires CARB to prepare a Scoping Plan that outlines the main state strategies for reducing GHG emissions to meet the 2020 deadline. In addition, AB 32 requires CARB to adopt regulations to require reporting and verification of statewide GHG emissions. Based on this guidance, CARB approved a 1990 statewide GHG level and 2020 target of 431 MMT CO2e, which was achieved in 2016. CARB approved the Scoping Plan on December 11, 2008, which included GHG emission reduction strategies related to energy efficiency, water use, and recycling and solid waste, among others (CARB 2008). Many of the GHG reduction measures included in the Scoping Plan (e.g., Low Carbon Fuel Standard, Advanced Clean Car standards, and Cap-and-Trade) have been adopted since the Scoping Plan’s approval.
The CARB approved the 2013 Scoping Plan update in May 2014 (CARB 2014). The update defined the CARB’s climate change priorities for the next five years, set the groundwork to reach post-2020 statewide goals, and highlighted California’s progress toward meeting the “near-term” 2020 GHG emission reduction goals defined in the original Scoping Plan. It also evaluated how to align the state’s longer term GHG reduction strategies with other state policy priorities, including those for water, waste, natural resources, clean energy, transportation, and land use (CARB 2014).
On September 8, 2016, the governor signed Senate Bill (SB) 32 into law, extending the California Global Warming Solutions Act of 2006 by requiring the state to further reduce GHG emissions to 40 percent below 1990 levels by 2030 (the other provisions of AB 32 remain unchanged). On December 14, 2017, the CARB adopted the 2017 Scoping Plan, which provides a framework for achieving the 2030 target. The 2017 Scoping Plan relies on the continuation and expansion of existing policies and regulations, such as the Cap-and-Trade Program, and implementation of recently adopted policies and legislation, such as SB 1383 and SB 100 (discussed later). The 2017 Scoping Plan also puts an increased emphasis on innovation, adoption of existing technology, and strategic investment to support its strategies. As with the 2013 Scoping Plan update, the 2017 Scoping Plan does not provide project-level thresholds for land use development. Instead, it recommends that local governments adopt policies and locally appropriate quantitative thresholds consistent with statewide per capita goals of six MT CO2e by 2030 and two MT CO2e by 2050 (CARB 2017). As stated in the 2017 Scoping Plan, these goals may be appropriate for plan-level analyses (city, county, sub-regional, or regional level), but not for specific individual projects because they include all emissions sectors in the state (CARB 2017).

SSEMBLY BILL 1279
AB 1279, the California Climate Crisis Act, was passed on September 16, 2022, and declares the State would achieve net zero GHG emissions as soon as possible, but no later than 2045, and to achieve and maintain net negative GHG emissions thereafter. In addition, the bill states that the State would reduce GHG emissions by 85 percent below 1990 levels no later than 2045.
In response to the passage of AB 1279 and the identification of the 2045 GHG reduction target, CARB published the Final 2022 Climate Change Scoping Plan in November 2022 (CARB 2022b). The 2022 Update builds upon the framework established by the 2008 Climate Change Scoping Plan and previous updates while identifying new, technologically feasible, cost-effective, and equity-focused Background
Air Quality and Greenhouse Gas Emissions Study 19
path to achieve California’s climate target. The 2022 Update includes policies to achieve a significant reduction in fossil fuel combustion, further reductions in short-lived climate pollutants, support for sustainable development, increased action on natural and working lands (NWL) to reduce emissions and sequester carbon, and the capture and storage of carbon.
The 2022 Update assesses the progress California is making toward reducing its GHG emissions by at least 40 percent below 1990 levels by 2030, as called for in SB 32 and laid out in the 2017 Scoping Plan, addresses recent legislation and direction from Governor Gavin Newsom, extends and expands upon these earlier plans, and implements a target of reducing anthropogenic emissions to 85 percent below 1990 levels by 2045, as well as taking an additional step of adding carbon neutrality as a science-based guide for California’s climate work. As stated in the 2022 Update, “The plan outlines how carbon neutrality can be achieved by taking bold steps to reduce GHGs to meet the anthropogenic emissions target and by expanding actions to capture and store carbon through the state’s NWL and using a variety of mechanical approaches” (CARB 2022b).
Specifically, the 2022 Update:
Identifies a path to keep California on track to meet its SB 32 GHG reduction target of at least 40 percent below 1990 emissions by 2030.
Identifies a technologically feasible, cost-effective path to achieve carbon neutrality by 2045 and a reduction in anthropogenic emissions by 85 percent below 1990 levels. Focuses on strategies for reducing California’s dependency on petroleum to provide consumers with clean energy options that address climate change, improve air quality, and support economic growth and clean sector jobs.
Integrates equity and protecting California’s most impacted communities as driving principles throughout the document.
Incorporates the contribution of NWL to the State’s GHG emissions, as well as their role in achieving carbon neutrality.
Relies on the most up-to-date science, including the need to deploy all viable tools to address the existential threat that climate change presents, including carbon capture and sequestration, as well as direct air capture.
Evaluates the substantial health and economic benefits of taking action. Identifies key implementation actions to ensure success.
In addition to reducing emissions from transportation, energy, and industrial sectors, the 2022 Update includes emissions and carbon sequestration in NWL and explores how NWL contribute to long-term climate goals. Under the Scoping Plan Scenario, California’s 2030 emissions are anticipated to be 48 percent below 1990 levels, representing an acceleration of the current SB 32 target. Cap-and-Trade regulation continues to play a large factor in the reduction of near-term emissions for meeting the accelerated 2030 reduction target. Every sector of the economy will need to begin to transition in this decade to meet our GHG emissions reduction goals and achieve carbon neutrality no later than 2045. The 2022 Update approaches decarbonization from two perspectives, managing a phasedown of existing energy sources and technologies, as well as increasing, developing, and deploying alternative clean energy sources and technology.

ENATE BILL 375 - 2008 SUSTAINABLE COMMUNITIES AND CLIMATE PROTECTION ACT SB 375, signed in August 2008, enhances the state’s ability to reach AB 32 goals by directing CARB to develop regional GHG emission reduction targets to be achieved from passenger vehicles by 2020 and 2035. In addition, SB 375 directs each of the state’s 18 major Metropolitan Planning Organizations (MPOs) to prepare a “sustainable communities strategy” (SCS) that contains a growth strategy to meet these emission targets for inclusion in the Regional Transportation Plan (RTP). On March 22, 2018, CARB adopted updated regional targets for reducing GHG emissions from 2005 levels by 2020 and 2035. SCAG was assigned targets of an 8 percent reduction in GHGs from transportation sources by 2020 and a 19 percent reduction in GHGs from transportation sources by 2035. In the SCAG region, SB 375 also provides the option for the coordinated development of sub regional plans by the sub regional councils of governments and the county transportation commissions to meet SB 375 requirements.
S
ENATE BILL 1383 - SHORT-LIVED CLIMATE POLLUTANTS
Adopted in September 2016, SB 1383 requires CARB to approve and begin implementing a comprehensive strategy to reduce emissions of short-lived climate pollutants. The bill requires the California Department of Resources Recycling and Recovery (CalRecycle), in consultation with CARB, to adopt regulations that achieve:
50-percent reduction in the level of the statewide disposal of organic waste from the 2014 level by 2020; and
75-percent reduction in the level of the statewide disposal of organic waste from the 2014 level by 2025.
The bill also mandates various state and local agencies develop further strategies to reduce emissions generated by specific industries such as agriculture. The stated goal is to achieve the following reduction targets by 2030:
Methane – 40 percent below 2013 levels
Hydrofluorocarbons – 40 percent below 2013 levels
Anthropogenic black carbon – 50 percent below 2013 levels SENATE BILL 100 - CALIFORNIA RENEWABLES PORTFOLIO STANDARD PROGRAM Adopted on September 10, 2018, SB 100 supports the reduction of GHG emissions from the electricity sector by accelerating the state’s Renewables Portfolio Standard Program, which was last updated by SB 350 in 2015. SB 100 requires electricity providers to increase procurement from eligible renewable energy resources to 33 percent of total retail sales by 2020, 60 percent by 2030, and 100 percent by 2045.
EXECUTIVE ORDER B-55-18 TO ACHIEVE CARBON NEUTRALITY
On September 10, 2018, Governor Brown issued Executive Order B-55-18, which established a new statewide goal of achieving carbon neutrality by 2045 and maintaining net negative emissions Background

California Building Standards Code
The California Code of Regulations (CCR) Title 24 is referred to as the California Building Standards Code. It consists of a compilation of several distinct standards and codes related to building construction including plumbing, electrical, interior acoustics, energy efficiency, and handicap accessibility for persons with physical and sensory disabilities. The current iteration is the 2022 Title 24 standards. The California Building Standards Code’s energy-efficiency and green building standards are outlined below.
P
ART 6 – BUILDING ENERGY EFFICIENCY STANDARDS/ENERGY CODE CCR Title 24, Part 6 is the Building Energy Efficiency Standards or California Energy Code. This code, originally enacted in 1978, establishes energy-efficiency standards for residential and non- residential buildings in order to reduce California’s energy demand. New construction and major renovations must demonstrate their compliance with the current Energy Code through submittal and approval of a Title 24 Compliance Report to the local building permit review authority and the California Energy Commission (CEC). The 2022 Title 24 standards are the applicable building energy efficiency standards for the proposed project because they became effective on January 1, 2023.

ART 11 – CALIFORNIA GREEN BUILDING STANDARDS
The California Green Building Standards Code, referred to as CALGreen, was added to Title 24 as Part 11, first in 2009 as a voluntary code, which then became mandatory effective January 1, 2011 (as part of the 2010 California Building Standards Code). The 2022 CALGreen includes mandatory minimum environmental performance standards for all ground-up new construction of residential and non-residential structures. It also includes voluntary tiers with stricter environmental performance standards for these same categories of residential and non-residential buildings. Local jurisdictions must enforce the minimum mandatory CALGreen standards and may adopt additional amendments for stricter requirements.

CITY OF PALMDALE GENERAL PLAN 2045
The City of Palmdale has established a series of goals and policies in the 2045 City of Palmdale General Plan to reduce GHG emissions and increase sustainability. The Sustainability, Climate, and Resilience chapter of the Plan serves as the Climate Action Plan (CAP) for the City of Palmdale. The City of Palmdale developed the CAP to reduce emissions and make Palmdale a more sustainable, healthier, and resilient community. Pursuant with CEQA Guidelines Section 15183.5, the CAP would meet the requirements of a qualified CAP and future residential projects developed under the Plan would be able to tier from the CAP for analysis purposes (City of Palmdale 2022).

Criteria pollutant and GHG emissions for project construction and operation were calculated using the California Emissions Estimator Model (CalEEMod), Version 2022.1. CalEEMod is a statewide land use emissions computer model designed to provide a uniform platform for government agencies, land use planners, and environmental professionals to quantify potential criteria pollutant and GHG emissions associated with both construction and operations from a variety of land use projects. The model was developed for the California Air Pollution Control Officers Association (CAPCOA) in collaboration with the California air districts. CalEEMod allows for the use of default data (e.g., emission factors, trip lengths, meteorology, source inventory) provided by the various California air districts to account for local requirements and conditions, and/or user- defined inputs. The calculation methodology and input data used in CalEEMod can be found in the CalEEMod User’s Guide (CAPCOA 2022). The input data and subsequent construction and operation emission estimates for the proposed project are discussed below. CalEEMod output files for the project are included in Appendix A to this report.
Construction Emissions
Project construction would primarily generate temporary criteria pollutant and GHG emissions from construction equipment operation on-site, construction worker vehicle trips to and from the site, and from import of materials to the site. Construction input data for CalEEMod include, but are not limited to: (1) the anticipated start and finish dates of construction activity; (2) inventories of construction equipment to be used; and (3) areas to be excavated and graded. The analysis assessed maximum daily emissions from individual construction activities, including site preparation, grading, building construction, paving, and architectural coating. Construction would require heavy equipment during demolition, site preparation, grading, building construction, and paving. Construction equipment estimates are based on surveys of construction projects within California conducted by members of CAPCOA. Note that there would be no demolition phase since the existing site is vacant.
Construction emissions were modeled in CalEEMod to occur over 18 months, starting in January 2024 with completion anticipated in July 2025. Although construction would likely begin in summer of 2024, this analysis conservatively assumes an earlier start date, as emissions factors for construction equipment are lower in later years. Construction emissions associated with development of the proposed project were quantified using the types and quantities of equipment for each construction phase as provided by the applicant. CalEEMod also estimates off-site emissions from worker, vendor, and hauling truck trips. The number of worker and vendor trips are based on CalEEMod defaults. Cut material would be used for construction of the proposed drainage basin; therefore, the project would not require material export or import.
The quantity, duration, and the intensity of construction activity influences the amount of construction emissions and their related pollutant concentrations that occur at any one time. The emission forecasts modeled for this report reflect conservative assumptions where a relatively large amount of construction is occurring in a relatively intensive manner. If construction is delayed or occurs over a longer period, emissions could be reduced because of (1) a more modern and Impact Analysis
Air Quality and Greenhouse Gas Emissions Study 25
cleaner-burning construction equipment fleet mix than assumed in the CalEEMod, and/or (2) a less intensive buildout schedule (i.e., fewer daily emissions occurring over a longer time interval).
Consistent with the industry standard, total construction GHG emissions resulting from a project were amortized over 30 years and added to operational GHG emissions to account for their contribution to GHG emissions over the lifetime of the project.
Operational Emissions
In CalEEMod, operational sources of criteria pollutant emissions include area, energy, and mobile sources; GHG emissions include water and solid waste sources in addition to area, energy, and mobile sources. The project’s single-family, ADU, and junior ADU uses were combined and attributed to the “Single Family Housing” land use subtype, while the proposed community amenities were modeled as a 2,630-square foot “Racquet Club.” Uncovered parking spaces and internal roadways were modeled as “Parking Lot.” The modeling analyzed 191 total dwelling units.
Energy Sources
Emissions from energy use typically include electricity and natural gas use. However, the proposed project would not include natural gas connections, and such emissions are therefore excluded from this analysis. Electricity emissions only apply to GHG emissions (as the energy is generated off-site and therefore may not be relevant for local and regional air quality conditions) and are calculated by multiplying the energy use times the carbon intensity of the utility district per kilowatt hour (CAPCOA 2022). The default electricity consumption values in CalEEMod include the CEC-sponsored California Commercial End Use Survey and Residential Appliance Saturation Survey studies.
Electricity emissions are calculated by multiplying the energy use times the carbon intensity of the utility district per kilowatt hour (CAPCOA 2022). The project would be served by Southern California Edison (SCE). Therefore, SCE’s specific energy intensity factors (i.e., the amount of CO 2,
CH4, and N2O per kilowatt-hour) are used in the calculations of GHG emissions.
Area Sources
Emissions associated with area sources, including consumer products, landscape maintenance, and architectural coating were calculated in CalEEMod and standard emission rates were utilized from CARB, USEPA, and emission factor values provided by the local air district (CAPCOA 2022).
Waste Sources
Operational emissions from waste generation were also calculated in CalEEMod and are based on the IPCC’s methods for quantifying GHG emissions from solid waste using the degradable organic content of waste (CAPCOA 2022). Waste disposal rates by land use and overall composition of municipal solid waste in California was primarily based on data provided by the California Department of Resources Recycling and Recovery (CalRecycle).
Water and Wastewater Sources
Operational emissions from water and wastewater usage calculated in CalEEMod were based on the default electricity intensity from the CEC’s 2006 Refining Estimates of Water-Related Energy Use in California using the average values for northern and southern California.

26 Mobile Sources
Mobile emissions are estimated by multiplying the project trip rate, average trip length, and the vehicle emission factors. The traffic consultant, General Technologies and Solutions (GTS), provided project-specific trip generations based on the Institute of Transportation Engineers (ITE) rates for “Single-Family Detached Housing” and “Multifamily Housing (Low-Rise)”. The trip rate was estimated to be 1,460 total trips. The project-specific trip generation rates provided are included in the CalEEMod outputs in Appendix A.
Significance Thresholds
Air Quality
To determine whether a project would result in a significant impact to air quality, Appendix G of the CEQA Guidelines requires consideration of whether a project would:
Conflict with or obstruct implementation of the applicable air quality plan; Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state ambient air quality standard; Expose sensitive receptors to substantial pollutant concentrations; or Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.
The AVAQMD has adopted numerical significant emissions thresholds to determine whether an air pollution source could contribute individually or cumulatively to the worsening local or regional air quality. These thresholds, which would apply to temporary construction and long-term operational emission, are shown in Table 3.
Table 3 AVAQMD Significance Thresholds
Pollutant Annual Threshold (tons/year) Daily Threshold (lbs/day) CO 100 548

Source: AVAQMD 2016
AVAQMD guidance states that a project would have a significant impact related to TACs if the project would expose sensitive receptors to pollutant concentrations resulting in a cancer risk greater than or equal to 10 in one million and/or a non-cancerous Hazard Index (HI) greater than or equal to one.
Impact Analysis
Air Quality and Greenhouse Gas Emissions Study 27
Greenhouse Gas Emissions
Based on Appendix G of the CEQA Guidelines, impacts related to GHG emissions from the project would be significant if the project would:
Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment; or
Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing GHG emissions.
The majority of individual projects do not generate sufficient GHG emissions to directly influence climate change. However, physical changes caused by a project can contribute incrementally to cumulative effects that are significant, even if individual changes resulting from a project are limited. The issue of climate change typically involves an analysis of whether a project’s contribution towards an impact would be cumulatively considerable. “Cumulatively considerable” means that the incremental effects of an individual project are significant when viewed in connection with the effects of past projects, other current projects, and probable future projects (CEQA Guidelines, Section 15064[h][1]).
Section 15064.4 of the CEQA Guidelines recommends that lead agencies quantify GHG emissions of projects and consider several other factors that may be used in the determination of significance of GHG emissions from a project, including the extent to which the project may increase or reduce GHG emissions; whether a project exceeds an applicable significance threshold; and the extent to which the project complies with regulations or requirements adopted to implement a plan for the reduction or mitigation of GHG emissions. The City of Palmdale has prepared a qualified CAP pursuant to CEQA Guidelines Section 15183.5(b). The CAP serves as a “qualified plan for the reduction of greenhouse gases” and provides a mechanism for tiering and streamlining of GHG emissions analysis for projects that are consistent with such a plan.
As part of the CAP, the City of Palmdale has established GHG reduction targets consistent with the statewide goal of reducing GHG emissions to 40 percent below 1990 levels by 2030 (478,418 MT CO
2e). Additionally, the CAP provides additional reductions beyond what is needed to achieve the 2017 Scoping Plan 2030 goal and advances the City’s progress toward the goal of carbon neutrality by 2045 contained in the 2022 Scoping Plan. To achieve these reductions, the City’s CAP has established per-service population emissions targets that are used for this analysis, which are: 2 MT CO
2e per service population by 2030; 1.3 MT CO2e per service population by 2035; and 1.2 MT CO2e per service population by 2045. Per-service population emissions are calculated by dividing total community emissions by the residents plus employees.
Impact Analysis
Air Quality
Air Quality Threshold 1
Would the project conflict with or obstruct implementation of the applicable air quality plan? (Less Than Significant).
The AVAQMD is required, pursuant to the federal Clean Air Act, to reduce emissions of criteria pollutants for which the AVAQMD portion of the MDAB is in nonattainment. Strategies to achieve these emissions reductions are developed in the 2023 Federal 70 ppb Ozone Attainment Plan (2023 Maison’s Palmdale Boulevard 150, LLC
Tentative Tract Map 83359 Project
28 Ozone Plan), prepared by AVAQMD for the region. Forecasts used in the 2023 Ozone Plan are developed by SCAG, which are based on local general plans and other related documents that are used to develop population, employment, and traffic projections. Consistency with the 2023 Ozone Plan is determined by analyzing a project with the assumptions in the Plan. As such, projects that propose development that is consistent with the growth anticipated by the local land use plan would be consistent with the SCAG growth projections and the 2023 Ozone Plan emissions estimates.
The project involves the construction of 191 residential units that would result in an increase in the city’s population. Based on an average household size of 3.4 persons per dwelling unit in the city, the project would house approximately 649 residents (California Department of Finance 2023). The population growth projections used in the 2023 Ozone Plan forecast show that the population of Palmdale will reach 207,000 residents by 2045, an increase of 48,400 from 2016 projections (SCAG 2020). The project's buildout would not exceed the 2023 Ozone Plan population growth forecast for Palmdale. The project’s population growth represents approximately 1.3 percent of the total population growth expected in Palmdale between 2016 and 2045. Therefore, the proposed project would be consistent with AQMP growth assumptions and accommodated within and consistent with the 2023 Ozone Plan, and impacts would be less than significant.
Air Quality Threshold 2
Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable federal or state ambient air quality standard (Less Than Significant).
Construction
Table 4 and Table 5 summarizes maximum daily and annual emissions of pollutants throughout the construction period of the project, respectively. Detailed modeling results are provided in Appendix A. Emissions would not exceed AVAQMD significance thresholds during project construction.
Therefore, project construction would not result in a cumulatively considerable net increase of a criteria pollutant, and impacts would be less than significant.

Table 6 summarizes emissions associated with operation of the project. The majority of operational emissions generated would be due to mobile emissions from vehicle trips to and from the project site. As shown in Table 6 and Table 7, emissions generated during the operation of project would not exceed AVAQMD significance thresholds. Therefore, the project would not result in a cumulatively considerable net increase of a criteria pollutant, and impacts would be less than significant.

Air Quality Threshold 3
Expose sensitive receptors to substantial pollutant concentrations (Less Than Significant).
Toxic Air Contaminants
CONSTRUCTION
Construction-related activities would result in short-term, project-generated emissions of DPM exhaust emissions from off-road, heavy-duty diesel equipment for site preparation grading, building construction, and other construction activities. DPM was identified as a TAC by CARB in 1998. The potential cancer risk from the inhalation of DPM (discussed in the following paragraphs) outweighs the potential non-cancer health impacts (CARB 2021b).
Generation of DPM from construction projects typically occurs in a single area for a short period.
Construction of the proposed project would occur over approximately 18months. The dose to Impact Analysis
Air Quality and Greenhouse Gas Emissions Study 31
which the receptors are exposed is the primary factor used to determine health risk. Dose is a function of the concentration of a substance or substances in the environment and the extent of exposure that a person has with the substance. Dose is positively correlated with time, meaning that a longer exposure period would result in a higher exposure level for the Maximally Exposed Individual. The risks estimated for a Maximally Exposed Individual are higher if a fixed exposure occurs over a longer period of time. According to the Office of Environmental Health Hazard Assessment (OEHHA), health risk assessments, which determine the exposure of sensitive receptors to toxic emissions, should be based on a 30-year exposure period (assumed to be the approximate time that a person spends in a household). OEHHA recommends this risk be bracketed with 9-year and 70-year exposure periods. Health risk assessments should be limited to the period/duration of activities associated with the project.
The maximum PM
2.5 emissions, which is used to represent DPM emissions for this analysis, would occur during site preparation and grading activities. While site preparation and grading emissions represent the worst-case condition, such activities would occur for three months, less than 3 percent for a 9-year health risk calculation period and less than one percent for a 30-year and 70- year health risk calculation period. PM2.5 emissions would decrease for the remaining construction period because construction activities such as building construction, architectural coating, and paving would require less construction equipment. Therefore, DPM generated by project, construction is not expected to create conditions where the probability that the Maximally Exposed Individual would contract cancer is greater than 10 in one million. This impact would be less than significant.
O
PERATION
CARB’s Air Quality and Land Use Handbook: A Community Health Perspective (2005) provides recommendations regarding the siting of new sensitive land uses near potential sources of air toxic emissions (e.g., freeways, distribution centers, rail yards, ports, refineries, chrome plating facilities, dry cleaners, and gasoline dispensing facilities). CARB guidelines provide the recommended siting distances both for the development of sensitive land uses in proximity to TAC sources and for the addition of new TAC sources in proximity to existing sensitive land uses. Residential land uses do not generate substantial TAC emissions based on the air toxic sources listed in CARB’s guidelines.
Therefore, the expected hazardous TACs generated on site (e.g., cleaning solvents, paints, landscape pesticides, etc.) for the proposed land uses would be below thresholds warranting further study under the California Accidental Release Program. The project would not expose off- site sensitive receptors to significant amounts of carcinogenic or TACs. Therefore, operational impacts would be less than significant.
Air Quality Threshold 4
Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people (Less Than Significant).
Sensitive receptors in the project vicinity include single-family residences at the project boundaries to the east, south and west, and approximately 800 feet to the north. Construction activities would be temporary and transitory and associated odors would cease upon construction completion.
Such odors disperse rapidly with distance. Accordingly, the proposed project would not create objectionable odors affecting a substantial number of people during construction, and short-term impacts would be less than significant.
Maison’s Palmdale Boulevard 150, LLC
Tentative Tract Map 83359 Project
32 The project does not include land uses typically associated with odor complaints such as sewage treatment plants, landfills, recycling facilities, and agricultural uses. Vehicles approaching, idling, and leaving the site may release odorous exhaust emissions. Odors of this nature disperse rapidly with distance and do not typically result in odor impacts. Additionally, the project site is located adjacent to Palmdale Boulevard, an arterial road, so vehicle exhaust is already prevalent in the project area. For these reasons, operational odor impacts would be less than significant.
Greenhouse Gas Emissions
GHG Emissions Threshold 1
Would the project generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment? (Less Than Significant With Mitigation Incorporated).
GHG Emissions Threshold 2
Would the project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing GHG emissions? (Less Than Significant With Mitigation Incorporated).
Project-generated Greenhouse Gas Emissions
The City of Palmdale CAP is a qualified GHG reduction plan consistent with the requirements of CEQA Guidelines Section 15183.5. In accordance with the CAP, project GHG emissions would be less than significant if it can be demonstrated that the project would be consistent with the CAP and generate less than 2 MT CO
2e per service population per year.
Project construction would generate temporary short-term GHG emissions through travel to and from the worksite and from the operation of construction equipment such as graders, backhoes, and generators. Construction of the project would generate approximately 1,546 MT CO2e over the entire construction period. As shown in Table 4, the proposed project’s amortized construction- related emissions would be 52 MT CO2e.
Operation of the proposed project would generate GHG emissions associated with area sources (e.g., landscape maintenance), energy and water usage, vehicle trips, and wastewater and solid waste generation. Table 8 combines the estimated construction and operational GHG emissions associated with development of the project. As shown therein, the project would generate approximately 2,206 MT of CO
2e per year during operation. Total emissions (amortized construction emissions plus annual operation emissions) would be 3.5 MT of CO2e per year per SP (conservatively rounded up to the nearest tenth). These emissions would exceed the 2.0 MT of CO
2e per year per service person goal of the City CAP, and impacts would be potentially significant.
Implementation of Mitigation Measure GHG-1 below would be required to reduce impacts to a less than significant level.

Consistency with Applicable Plans
2022 Scoping Plan
The principal state plans and policies for reducing GHG emissions are AB 32, SB 32, and AB 1279.
The quantitative goal of AB 32 is to reduce GHG emissions to 1990 levels by 2020; the goal of SB 32 is to reduce GHG emissions to 40 percent below 1990 levels by 2030; and the goal of AB 1279 is to achieve net zero greenhouse gas emissions no later than 2045, and reduce GHG emissions by 85 percent below 1990 levels no later than 2045. The 2022 Scoping Plan expands upon earlier plans to include the AB 1279 targets. The 2022 Scoping Plan’s strategies that are applicable to the proposed project include reducing fossil fuel use and vehicle miles traveled; decarbonizing the electricity sector, maximizing recycling and diversion from landfills; and increasing water conservation. The project would be consistent with these goals through project design, which includes 100% electric project design, complying with the latest Title 24 Green Building Code and Building Efficiency Energy Standards, and complying with the AB 341 waste diversion goal of 75 percent. In addition, the project would receive electricity from SCE, which is required to reduce GHG emissions by increasing procurement from eligible renewable energy by set target years as required by SB 100. Therefore, the project would not conflict with the 2022 Scoping Plan.
Connect SoCal: 2020-2045 SCAG RTP/SCS
According to the 2020-2045 RTP/SCS, the updated targets for the SCAG region are eight percent below 2005 per capita emission levels by 2020 (this value is unchanged from the previous 2020 CARB target) and 19 percent below 2005 per capita emissions levels by 2035. The revised 2035 target is higher than the previous CARB target of 13 percent for the SCAG region. The 2020-2045 RTP/SCS includes implementation strategies for focusing growth near destinations and mobility options, promoting diverse housing choices, leveraging technology innovations, supporting implementation of sustainability policies, and promoting a green region. Further specific actions to reduce GHG emissions under the 2020-2045 RTP/SCS include designing transportation options that reduce the reliance on solo car trips, promoting low emission technologies such as electric vehicles Maison’s Palmdale Boulevard 150, LLC

Goal 2: Improve mobility, accessibility,
reliability, and travel safety for people
and goods
Consistent. The project would include interior roadways, sidewalks, and trails to provide vehicle, bicycle, and pedestrian access to residences. This expanded pedestrian network would provide pedestrian access to local schools and parks, including Domenic Massari Park and Knight High School to the southeast, as well as commercial uses to the west. Therefore, the project would have accessible and reliable travel options and be designed to reduce reliance on solo vehicle trips.
Goal 5: Reduce greenhouse gas
emissions and improve air quality
Consistent. The project would include several sustainable design features, including those required by Title 24 and CALGreen standards. The project would include photovoltaic systems and battery storage installed on each residential building. All proposed residences would be equipped with energy-efficient appliances and lighting, water-efficient fixtures, and water- efficient irrigation systems. The project would meet the requirements of the 2022 California Energy Code.
Goal 6: Support healthy and equitable
communities
Consistent. The project would provide housing near city parks, commercial areas, and schools. Furthermore, the project would include design features such as sidewalks and multiple access points to the project site. These features would promote active transportation and foster efficient development patterns within the project site vicinity.
Goal 9: Encourage development of
diverse housing types in areas that are
supported by multiple
transportation
options
Consistent. The project would include interior roadways, sidewalks, and trails to provide vehicle, bicycle, and pedestrian access to residences. This expanded pedestrian network would provide pedestrian access to local schools and parks, including Domenic Massari Park and Knight High School to the southeast. The project would be near a commercial downtown area along 47th Street and East Avenue R. The project would include improvement of pedestrian and bicycle facilities, and site access would be provided along several access points. Proposed on-site facilities would establish residences on an underutilized lot adjacent to existing development. Therefore, the project would provide connectivity with planned neighboring residential developments.

City of Palmdale Climate Action Plan
The project’s consistency with the City of Palmdale General Plan and CAP policies aimed at reducing GHG emissions are shown in Table 10. Although the project would be consistent with applicable policies from the City of Palmdale General Plan and CAP shown in Table 9, it would exceed the CAP’s per service population thresholds as shown in Table 6, above. Therefore, the project would be inconsistent with the CAP, and impacts would be potentially significant.

pedestrians and cyclists, which would connect to existing and planned off-site pedestrian and bicycle facilities.
Goal SCR-3: Green and decarbonized buildings for new
construction and major renovations.

adopting a local reach code to encourage new buildings
to be all-electric.
Policy SCR-3.3: Solar + Storage. Require installation of photovoltaic panels and battery storage on all residential new construction and nonresidential new construction
over 5,000 sq. ft.
Consistent. The project would comply with all standards set forth in the CBC Title 24, which would minimize the
wasteful, inefficient, or unnecessary consumption of energy resources during operation.
Furthermore, in accordance
with the 2022 California Green Building Standards for
residential developments, low-rise residences (three stories or less) are required to install on-site photovoltaic arrays.
The project would include solar rooftop photovoltaic
systems, in addition to battery storage. All proposed
residences would be equipped with energy-efficient
appliances and lighting, water-efficient fixtures, and water- efficient irrigation systems. As mentioned above under the 2022 Scoping Plan, the project would be consistent with the State’s climate goals by increasing renewable energy and providing energy efficiency in the buildings.

In summary, the plan consistency analysis provided above demonstrates that the project complies with or exceeds the plans, policies, regulations and GHG reduction actions/strategies outlined in SCAG’s 2020-2045 RTP/SCS and the 2022 Scoping Plan. However, the project would exceed the per service population threshold established by the City and would therefore be inconsistent with the City’s 2045 General Plan and CAP. Therefore, the project would conflict with an applicable plan, policy, or regulation of an agency adopted for the purpose of reducing emissions of GHG emissions.
Implementation of Mitigation Measure GHG-1 below would reduce project related emissions to a less than significant level.
Mitigation Measures
GHG-1 Greenhouse Gas Reduction Plan
The project applicant shall prepare and implement a GHG Reduction Plan (GHGRP) that demonstrates emissions reductions from project operation by approximately 1,004 MT of CO2e per year to 1,254 MT of CO2e per year for the lifetime of the project, or by an amount determined through further analysis of project GHG emissions at the time of GHGRP preparation. Potential GHG reduction measures included in the GHGRP may include, but would not be limited to, the following on-site measures:
Construction of buildings that achieve energy and water efficiencies beyond those specified in the California Code of Regulations, Title 24 requirements Implementation of green building practices and/or cool roofs Installation of energy-efficient equipment and appliances exceeding California Green Building Code standards
Maison’s Palmdale Boulevard 150, LLC
Tentative Tract Map 83359 Project
36 Installation of outdoor water conservation and recycling features, such as smart irrigation controllers and reclaimed water usage
Installation of low-flow bathroom and kitchen fixtures and fittings Installation of light emitting diode (LED) lights
Implementation of waste reduction programs that may include waste minimization, waste diversion, composting, and material reuse/recycling
Provision of incentives and outreach that promote alternative transportation and transit use to future employees and patrons
Promotion of alternative fuel vehicles, including through the installation of electric vehicle charging infrastructure beyond those required
If GHG emissions cannot be feasibly reduced through implementation of on-site measures, the following off-site measures may be implemented:
Directly undertake or fund activities that reduce or sequester GHG emissions (“Direct Reduction Activities”) and retire the associated “GHG Mitigation Reduction Credits.” A “GHG Mitigation Reduction Credit” shall mean an instrument issued by an Approved Registry and shall represent the estimated reduction or sequestration of 1 MT of CO2e that shall be achieved by a Direct Reduction Activity that is not otherwise required (CEQA Guidelines Section 15126.4[c][3]). A “GHG Mitigation Reduction Credit” must achieve GHG emission reductions that are real, permanent, quantifiable, verifiable, enforceable, and in addition to any GHG emission reduction required by law or regulation or any other GHG emission reduction that otherwise would occur in accordance with the criteria set forth in the California Air Resources Board’s most recent Process for the Review and Approval of Compliance Offset Protocols in Support of the Cap-and-Trade Regulation (2013). An “Approved Registry” is an accredited carbon registry that follows approved California Air Resources Board Compliance Offset Protocols. At this time, Approved Registries include American Carbon Registry, Climate Action Reserve, and Verra (California Air Resources Board 2018). Credits from other sources will not be allowed unless they are shown to be validated by protocols and methods equivalent to or more stringent than the California Air Resources Board standards. In the event that a project or program providing GHG Mitigation Reduction Credits to the project applicant loses its accreditation, the project applicant shall comply with the rules and procedures of retiring GHG Mitigation Reduction Credits specific to the registry involved and shall undertake additional direct investments to recoup the loss.
Obtain and retire “Carbon Offsets.” “Carbon Offset” shall mean an instrument issued by an Approved Registry and shall represent the past reduction or sequestration of 1 MT of CO2e achieved by a Direct Reduction Activity or any other GHG emission reduction project or activity that is not otherwise required (CEQA Guidelines Section 15126.4[c][3]). A “Carbon Offset” must achieve GHG emission reductions that are real, permanent, quantifiable, verifiable, enforceable, and in addition to any GHG emission reduction required by law or regulation or any other GHG emission reduction that otherwise would occur in accordance with the criteria set forth in the California Air Resources Board’s most recent Process for the Review and Approval of Compliance Offset Protocols in Support of the Cap-and-Trade Regulation (2013). If the project applicant chooses to meet some of the GHG reduction requirements by purchasing offsets on an annual and permanent basis, the offsets shall be purchased according to the City’s preference, which is, in order of the City’s preference: (1) within Palmdale; (2) within the air basin; (3) within the State of California; then (4) elsewhere in the United States. In the event Impact Analysis

that a project or program providing offsets to the project applicant loses its accreditation, the project applicant shall comply with the rules and procedures of retiring offsets specific to the registry involved and shall purchase an equivalent number of credits to recoup the loss.
The GHGRP shall be submitted by the project developer and reviewed and approved by the City of Palmdale as being in compliance with this measure prior to building permit issuance. Applicable elements of the approved GHGRP shall be reflected on project site plans prior to certificate of occupancy. Condition compliance shall include monitoring and verifying implementation of measures included in the GHGRP.
Significance After Mitigation
To implement Mitigation Measure GHG-1, the project applicant may choose to apply a wide variety of GHG emission reduction measures, including carbon offsets, to reduce project-related emissions to 1,254 MT of CO2e per year. Therefore, implementation of Mitigation Measure GHG-1 would reduce project-related emissions below the threshold of significance of 1,254 MT of CO2e per year or 2 MT of CO2e per service population per year. Impacts would be less than significant with mitigation incorporated.

Air Quality Summary
As shown in Table 4, Table 5, and Table 6, project construction and operational emissions would not exceed applicable significance thresholds for all criteria pollutants. Furthermore, growth facilitated by the proposed project would not exceed SCAG growth projections, and would not conflict with the AVAQMD’s 2023 Ozone Attainment Plan. The project’s criteria pollutant emissions impacts would be less than significant.
The project would generate TAC emissions including DPM exhaust emissions associated with use of heavy-duty diesel construction equipment. As discussed under Air Quality Threshold 3, health risks at the nearest sensitive receptors resulting from construction and operation of the project would be well below applicable thresholds. Thus, impacts from the project’s TAC emissions would be less than significant.
The project does not include land uses typically associated with odor complaints such as sewage treatment plants, landfills, recycling facilities, and agricultural uses. During construction, the project would temporarily generate diesel exhaust odors from use of heavy-duty equipment and during operation the project would generate vehicle exhaust and fugitive fuel vapors may be released. These types of odors dissipate quickly with distance and do not typically result in odor impacts. Additionally, as the project site is located adjacent to an arterial road, East Palmdale Boulevard, vehicle exhaust is already prevalent. For these reasons, operational odor impacts would be less than significant.
As detailed above, construction and operation of the project would not result in significant air quality impacts.
Greenhouse Gas Emissions Summary
The project would result in an overall GHG emissions of 2,284 MT CO2e per year. The majority of these emissions would result from vehicle trips to and from the site.
The City of Palmdale has adopted a CAP that meets the requirements under CEQA Guidelines Section 15183.5 for a qualified GHG reduction plan. Therefore, this project-level analysis is streamlined by tiering off the Palmdale CAP. As discussed above, the proposed project’s emissions per service population would be approximately 3.5 MT CO 2e per year, which exceeds the threshold
set forth in the CAP of 2.0 MT CO2e per service population per year. Therefore, the project’s incremental contribution to a global climate would be potentially significant. Implementation of Mitigation Measure GHG-1 would require the developer to implement a GHG Reduction Plan. Such mitigation would reduce project emissions to below the established threshold and ensure that the project would not conflict with an applicable plan, policy or regulation adopted for the purpose of reducing GHG emissions.
