Agenda — Roseville City Council, January 19, 2022 (part 9 of 9)

Introduction
The Westbrook Parcel WB-41 Residential Development (project) is located south of Pleasant Grove Boulevard, between Santucci Boulevard and Daylight Drive in Roseville, California. The project is located within the Sierra Vista Specific Plan (SVSP). The project area and tentative subdivision map are provided as Figures 1 and 2, respectively.

Due to the proximity of the proposed residential uses to Pleasant Grove Boulevard and Santucci Boulevard, BAC was retained by the project applicant to prepare this assessment. Specifically, the purposes of this assessment are to quantify noise levels associated with traffic on those roadways, and to compare those levels against the applicable City of Roseville and Sierra Vista Specific Plan noise criteria for new residential uses.

Noise Fundamentals and Terminology
Noise is often described as unwanted sound. Sound is defined as any pressure variation in air that the human ear can detect. If the pressure variations occur frequently enough (at least 20 times per second), they can be heard, and thus are called sound. Measuring sound directly in terms of pressure would require a very large and awkward range of numbers. To avoid this, the decibel scale was devised. The decibel scale allows a million-fold increase in pressure to be expressed as 120 dB. Another useful aspect of the decibel scale is that changes in levels (dB) correspond closely to human perception of relative loudness. Appendix A contains definitions of Acoustical Terminology. Figure 3 shows common noise levels associated with various sources.

The perceived loudness of sounds is dependent upon many factors, including sound pressure level and frequency content. However, within the usual range of environmental noise levels, perception of loudness is relatively predictable, and can be approximated by weighing the frequency response of a sound level meter by means of the standardized A-weighing network.

There is a strong correlation between A-weighted sound levels (expressed as dBA) and community response to noise. For this reason, the A-weighted sound level has become the standard tool of environmental noise assessment. All noise levels reported in this section are in terms of A-weighted levels in decibels.

Community noise is commonly described in terms of the “ambient” noise level, which is defined as the all-encompassing noise level associated with a given noise environment. A common statistical tool to measure the ambient noise level is the average, or equivalent, sound level (Leq) over a given time period (usually one hour). The Leq is the foundation of the Day-Night Average Level noise descriptor, Ldn or DNL, and shows very good correlation with community response to noise.

Figure 3
Typical A-Weighted Sound Levels of Common Noise Sources The Day-Night Average Level (DNL) is based upon the average noise level over a 24-hour day, with a +10-decibel weighting applied to noise occurring during nighttime (10:00 p.m. to 7:00 a.m.) hours. The nighttime penalty is based upon the assumption that people react to nighttime noise exposures as though they were twice as loud as daytime exposures. Because DNL represents a 24-hour average, it tends to disguise short-term variations in the noise environment. DNL-based noise standards are commonly used to assess noise impacts associated with traffic, railroad, and aircraft noise sources.

Criteria for Acceptable Noise Exposure
City of Roseville General Plan 2035
The Noise Element of the Roseville General Plan 2035 contains goals and policies intended to protect city residents from the harmful and annoying effects of exposure to excessive noise.

The General Plan policies which would be applicable to this project are reproduced below:

Transportation Noise Sources
Policy 1 Allow the development of new noise-sensitive land uses (which include but are not limited to residential, schools, and hospitals) only in areas exposed to existing or projected levels of noise from transportation noise sources which satisfy the levels specified in Table 1. Noise mitigation measures may be required to reduce noise in outdoor activity areas and interior spaces to the levels specified in Table 1.

Recognizing that in increasingly urban areas it is difficult to maintain suburban noise standards, and in order to facilitate the City’s goals to encourage reinvestment and economic development in the Riverside and Downtown Specific Plan areas, the City may elect to allow new noise-sensitive land uses on a case by case basis in proximity to transportation sources. Noise mitigation, including an acoustical analysis, would be required to reduce interior space noise levels to the standards specified in Table 1. Exterior noise levels would require mitigation to the extent feasible using building orientation, construction, and design features; however ultimately, noise levels may exceed the noise standards identified in Table 1.

Policy 2 Require new roadway improvement projects to be mitigated so as not to exceed the noise levels specified in Table 1 at outdoor activity areas or interior spaces of existing noise-sensitive land uses.

Policy 3 Evaluate new transportation projects, such as light and heavy rail, using the standards contained in Table 1. However, noise from these projects may be allowed to exceed the standards contained in Table 1 if the City Council finds that there are special overriding circumstances.

Policy 4 Require an acoustical analysis where:
a. Noise sensitive land uses are proposed in areas exposed to existing or projected noise levels exceeding the levels specified in Table 1; b. Proposed transportation noise source projects are likely to produce noise levels exceeding the levels specified in Table 1 at existing or planned noisesensitive uses.

1 Outdoor activity areas for residential developments are considered to be the backyard patios or decks of single-family dwelling, and the patios or common areas where people generally congregate for multi-family development.

Outdoor activity areas for non-residential developments are considered to be those common areas where people generally congregate, including pedestrian plazas, seating areas and outside lunch facilities.

Where the location of outdoor activity areas is unknown, the exterior noise level standard shall be applied to the property line of the receiving land use.
2 As determined for a typical worst-case hour during periods of use. 3 Where it is not possible to reduce noise in outdoor activity areas to 60 dB Ldn/CNEL or less using a practical application of the best-available noise reduction measures, an exterior noise level of up to 75 dB Ldn/CNEL may be allowed provided that available exterior noise level reduction measures have been implemented and interior noise levels are in compliance with this table.

Note: Where a proposed use is not specifically listed on this table, the use shall comply with the noise exposure standards for the nearest similar use as determined by the Planning Department. Commercial and industrial uses have not been listed because such uses are not considered to be particularly sensitive to noise exposure. -- = not applicable

Sierra Vista Specific Plan Final EIR
The Sierra Vista Specific Plan (SVSP) Final EIR (May 2010) contains mitigation measures intended to protect future city residents from the harmful and annoying effects of exposure to excessive noise. The transportation noise related mitigation measures of the specific plan are reproduced below:

WMM 4.5-8 On-site Traffic Noise Attenuation (Impact 4.6-6 SVSP and Urban Reserve) The project developer shall demonstrate through an acoustical study that residences along roadways will be subject to noise levels consistent with the Bollard Acoustical Consultants, Inc. (BAC)
Environmental Noise Assessment
Westbrook Parcel WB-41 Residential Development – Roseville, California

Page 7 ends

City’s standards. The standards could be achieved through a combination of setbacks, sound walls or other barriers, building orientation or other measures.

An acoustical analysis shall be required to demonstrate that these measures will result in acceptable noise levels.

WMM 4.5-10 On-site Traffic Noise Policies (Impact 4.6-6 and 4.6-8 Urban Reserve) Specific Plans and/or other development proposals in the Remainder Area Urban Reserve shall include policies and/or conditions that require that residential development adjacent to roadways will be subject to traffic noise levels that fall within City standards. The standards could be achieved through a combination of setbacks, sound walls or other barriers, building orientation or other measures. An acoustical analysis shall be required to demonstrate that these measures will result in acceptable noise levels.

MM 4.6- 4: Traffic Noise Attenuation (Impact 4.6-6 and 4.6-8 SVSP) MM 4.6-4(a): Masonry walls and/or landscaped berms shall be constructed along the major project-area roadways adjacent to proposed residential uses if acoustical studies warrant sound attenuation, otherwise standard wood fencing is acceptable. Draft EIR Table 4.6-10 data shall be consulted to determine appropriate barrier heights. If the assumptions shown in Table 4.6-10 vary considerably, a detailed analysis of exterior and interior mitigation measures should be conducted when tentative maps become available.

MM 4.6-4(b): In areas requiring sound attenuation, noise barrier walls shall be constructed of concrete panels, concrete masonry units, earthen berms, or any combination of these materials. Wood is not recommended for construction due to eventual warping and degradation of acoustical performance.

MM 4.6-4(c): Tentative map applications for residential uses located along Fiddyment Road would be required to include an analysis of interior noise levels. The report shall be conducted by a qualified acoustical engineer and shall specify the measures required to achieve compliance with the City of Roseville 45 dB DNL interior noise level standard.

Evaluation of Future Traffic Noise Environment at Project Site Traffic Noise Prediction Methodology
The Federal Highway Administration Highway Traffic Noise Prediction Model (FHWA-RD-77- 108) was used to predict traffic noise levels at project subdivisions. The model is based upon the CALVENO noise emission factors for automobiles, medium trucks, and heavy trucks, with consideration given to vehicle volume, speed, roadway configuration, distance to the receiver, and the acoustical characteristics of the site. The FHWA Model was developed to predict hourly Bollard Acoustical Consultants, Inc. (BAC)
Environmental Noise Assessment
Westbrook Parcel WB-41 Residential Development – Roseville, California

Page 8 ends

Leq values for free-flowing traffic conditions and is considered to be accurate within 1.5 dB in most situations.

Predicted Future Exterior Traffic Noise Levels
The FHWA Model was used with future traffic data to predict future Pleasant Grove Boulevard and Santucci Boulevard traffic noise levels at the project site. Future daily traffic (ADT) volumes for the roadways were calculated using data obtained from the Sierra Vista Specific Plan Traffic Impact Analysis prepared by DKS Associates (2009). Specifically, the future average daily traffic (ADT) volumes for the roadways were conservatively estimated by applying a factor of 5 to the sum of AM and PM peak hour conditions (Cumulative Plus Project). A complete listing of FHWA Model inputs and predicted future traffic noise levels at the project site are contained in Appendix B and are summarized in Table 2.

Exterior Traffic Noise Compliance Evaluation
As indicated in Table 2, future Pleasant Grove Boulevard and Santucci Boulevard traffic noise levels at the proposed outdoor activity areas (backyards) nearest to the roadways are predicted to exceed the City of Roseville General Plan exterior noise level standard of 60 dB DNL.

However, the project site plans indicate that masonry walls (Proto II system construction) are proposed to be constructed along Pleasant Grove Boulevard and Santucci Boulevard at the locations shown on Figure 2. The results presented in Table 3 below contain predicted future traffic noise levels at proposed ground level locations with consideration of the noise attenuation that would be provided by the proposed masonry walls. Barrier effectiveness worksheets for the walls are provided in Appendix C. Because elevated upper-floor building facades of the residences constructed adjacent to the roadways would not receive shielding from the masonry walls, barrier analyses were not conducted for those locations.

It should be noted that, although the project site plans show the locations of the masonry walls, information pertaining to the overall heights of said walls is not included. For the purposes of this analysis, it was assumed that the masonry walls will have a minimum height of 6-feet.

The Table 3 data indicate that future Pleasant Grove Boulevard and Santucci Boulevard traffic noise levels at the proposed outdoor activity areas (backyards) nearest to the roadways are predicted to satisfy the City of Roseville General Plan exterior noise level standard of 60 dB DNL, including consideration of the shielding provided by masonry walls having a minimum height of 6-feet at the locations illustrated in Figure 2. Thus, provided that masonry walls having a minimum height of 6-feet are constructed at the locations shown in Figure 2, no further consideration of exterior Pleasant Grove Boulevard or Santucci Boulevard traffic noise mitigation measures would be warranted for the project. It should be noted that the 6-foot wall height required for compliance indicated above is relative to adjacent residential lot or roadway elevation, whichever is greater.

Interior Traffic Noise Compliance Evaluation
As indicated in Table 3, future Pleasant Grove Boulevard and Santucci Boulevard traffic noise levels at the first-floor building facades nearest to the roadways are predicted to range from 56 to 60 dB DNL, including consideration of the shielding that would be provided by the masonry walls. Due to reduced ground absorption at elevated positions and lack of screening by the walls, future traffic noise levels at the upper-floor facades of those residences are predicted to range from 64 to 68 dB DNL. To satisfy the City of Roseville General Plan 45 dB DNL interior noise level standard, minimum noise reductions of 15 dB and 23 dB would be required of the first- and upper-floor building facades (respectively) of the residences constructed adjacent to the roadways.

Standard residential construction (stucco siding, STC-27 windows, door weather-stripping, exterior wall insulation, composition plywood roof), typically results in an exterior to interior noise reduction of at least 25 dB with windows closed and approximately 15 dB with windows open.

This level of noise reduction would be adequate to reduce future Pleasant Grove Boulevard and Santucci Boulevard traffic noise levels within all floors of residences in this development to 45 dB DNL or less, which would satisfy the General Plan 45 dB DNL interior noise level standard for residential uses. Nonetheless, mechanical ventilation (air conditioning) should be provided Bollard Acoustical Consultants, Inc. (BAC)

for all residences within this development to allow the occupants to close doors and windows as desired for additional acoustical isolation.

Conclusions & Recommendations
The Westbrook Parcel WB-41 Residential Development is predicted to be exposed to future Pleasant Grove Boulevard and Santucci Boulevard traffic noise exposure in compliance with the applicable City of Roseville General Plan 60 dB DNL exterior noise level standard for residential uses provided that the project design includes the construction of masonry walls having a minimum height of 6-feet at the locations shown on Figure 2 (as proposed). The minimum masonry wall height of 6-feet required for compliance is relative to adjacent residential lot or roadway elevation, whichever is greater.

In addition, standard residential construction (stucco siding, STC-27 windows, door weatherstripping, exterior wall insulation, composition plywood roof) would be adequate to reduce future Pleasant Grove Boulevard and Santucci Boulevard traffic noise levels within all floors of residences in this development to 45 dB DNL or less, which would satisfy the applicable City of Roseville General Plan 45 dB DNL interior noise level standard for residential uses.

Nonetheless, mechanical ventilation (air conditioning) should be provided for all residences within this development to allow the occupants to close doors and windows as desired for additional acoustical isolation.

These conclusions are based on the future traffic data cited in Appendix B, the project site plan shown on Figure 2, and on noise reduction data for standard residential dwellings and for typical STC rated window data. Deviations from the above-mentioned resources could cause future traffic noise levels to differ from those predicted in this assessment. In addition, Bollard Acoustical Consultants, Inc. is not responsible for degradation in acoustic performance of the residential construction due to poor construction practices, failure to comply with applicable building code requirements, or for failure to adhere to the minimum building practices cited in this report.

This concludes BAC’s traffic noise assessment for the proposed Westbrook Parcel WB-41 Residential Development in Roseville, California. Please contact BAC at (916) 663-0500 or [email protected] with any questions regarding this assessment.

Appendix A
Acoustical Terminology
Acoustics The science of sound.

Ambient Noise The distinctive acoustical characteristics of a given space consisting of all noise sources audible at that location. In many cases, the term ambient is used to describe an existing or pre-project condition such as the setting in an environmental noise study.

Attenuation The reduction of an acoustic signal.

A-Weighting A frequency-response adjustment of a sound level meter that conditions the output signal to approximate human response.

Decibel or dB Fundamental unit of sound. A Bell is defined as the logarithm of the ratio of the sound pressure squared over the reference pressure squared. A Decibel is one-tenth of a Bell.

CNEL Community Noise Equivalent Level. Defined as the 24-hour average noise level with noise occurring during evening hours (7 - 10 p.m.) weighted by a factor of three and nighttime hours weighted by a factor of 10 prior to averaging.

Frequency The measure of the rapidity of alterations of a periodic signal, expressed in cycles per second or hertz.

IIC Impact Insulation Class (IIC): A single-number representation of a floor/ceiling partition’s impact generated noise insulation performance. The field-measured version of this number is the FIIC.

Ldn Day/Night Average Sound Level. Similar to CNEL but with no evening weighting.

Leq Equivalent or energy-averaged sound level.

Lmax The highest root-mean-square (RMS) sound level measured over a given period of time.

Loudness A subjective term for the sensation of the magnitude of sound.

Masking The amount (or the process) by which the threshold of audibility is for one sound is raised by the presence of another (masking) sound.

Noise Unwanted sound.

Peak Noise The level corresponding to the highest (not RMS) sound pressure measured over a given period of time. This term is often confused with the “Maximum” level, which is the highest RMS level.

RT60 The time it takes reverberant sound to decay by 60 dB once the source has been removed.

STC Sound Transmission Class (STC): A single-number representation of a partition’s noise insulation performance. This number is based on laboratory-measured, 16-band (1/3- octave) transmission loss (TL) data of the subject partition. The field-measured version of this number is the FSTC.

Subject: Transportation Evaluation of Proposed Rezone of Sierra Vista Specific Plan Parcel WB-41 RS21-4077
This memorandum presents the assumptions, analysis methods, and results of our evaluation of the proposed rezone of Parcel WB-41 in the Sierra Vista Specific Plan (SVSP). The analysis focuses on how conditions would change under cumulative (2035) conditions because the surrounding area is mostly undeveloped. A baseline analysis would therefore not be meaningful.

Proposed Land Use Changes
The project site is situated in the southeast corner of the Pleasant Grove Boulevard/Santucci Boulevard intersection. The proposed project would rezone the 10.1-acre Parcel WB-41 from community commercial to medium density residential. Refer to Figure 1 for project location and Figure 2 for project site plan for the proposed medium density residential.

The Sierra Vista Specific Plan (2010) indicates that community commercial parcels could be constructed with a floor-to-area ratio (FAR) of up to 0.4. However, experience on other retail parcels in the City suggests a 0.25 FAR is a more reasonable yield. Accordingly, it is assumed the existing zoning would yield 110,000 square feet of retail space.

According to the project site plan (Tentative Subdivision Map for Sierra Vista Specific Plan Parcel WB41, MacKay & Somps, April 2021) the proposed rezone would yield 63 single-family detached dwelling units.

Trip Generation Comparison
We compared the trip generation of Parcel 41 based on its existing and proposed zoning using trip generation rates from the City of Roseville 2035 travel demand model1 . Table 1 shows the results,
and indicates that the proposed rezoning would result in substantially fewer trips generated by the property. This suggests that traffic volumes in the vicinity of the project would be reduced during peak hours and on a daily basis as a result of the land use change. 1 Trip rates from the City’s model were used for this comparison because subsequent analysis of changes in external travel (i.e., at the specific plan boundary) also rely on the City’s travel demand model and rates.

AM peak hour rate estimated by calculating the difference in trip rates from the City’s model (for PM peak hour and daily) versus the Trip Generation Manual (ITE, 2017) and applying this factor to ITE’s AM peak hour rate. ksf = thousand square feet. du’s = dwelling units.

Source: Fehr & Peers, 2021.

External Trip Generation Comparison
The proposed land use change would reduce the overall amount of retail in the SVSP. An analysis was performed to determine whether the reduction in retail would cause a greater amount of Specific Plan trips to be external to the Plan.

The analysis was performed using the City’s 2035 travel demand model. Trips generated by the Specific Plan were tracked as either remaining internal or being external to the plan. The results are shown in Table 2 and indicate that the proposed rezone would result in fewer external AM and PM peak hour and daily trips generated by the Specific Plan when compared to the existing zoning.

Vehicle Miles Traveled (VMT)
VMT was calculated using the City of Roseville 2035 travel demand model on a Citywide basis (i.e., travel generated by all land uses within the city) and for the SVSP only. The model was run with the existing and proposed rezoning. The results are shown in Table 3 and indicate that the rezone would decrease in total VMT both for the SVSP only and for the City as a whole.

Table 3
VMT Comparison – 2035 With Existing vs. Proposed Zoning City of Roseville Total VMT Sierra Vista Specific Plan Total VMT 2035 with Existing Zoning 9,728,939 837,375
2035 with Proposed Zoning 9,711,358 825,776
Difference -17,581 -11,599
Notes:

1. Source: City of Roseville travel demand model output.

When compared to the existing zoning, the proposed rezone would generate fewer site trips, fewer trips entering/exiting the SVSP area, and less VMT. Thus, there would be no adverse effects to the roadway network caused by the rezone.

We hope this information is helpful. Please with any questions or comments.

ADDENDUM ATTACHMENT 6A
Project Description:

The project site is an undeveloped 10.11-acre parcel (APN 496-100-030-000) located on Parcel WB-41 of the Sierra Vista Specific Plan (SVSP), which was approved on May 5, 2010. The address of the property is 3301 Pleasant Grove Boulevard. The Environmental Impact Report (EIR) for the SVSP included an evaluation of the Cultural and Paleontological Resources within the project area. The proposed project will not result in any additional ground disturbance that was not considered in the EIR for the SVSP. The site has an existing General Plan land use designation and zoning designation of Community Commercial (CC). The site is adjacent to vacant High Density Residential (HDR) parcels to the north across Pleasant Grove Boulevard, a Low Density Residential (LDR) parcel currently under construction to the east across Daylight Drive, a lift station and a LDR parcel to the south, and agricultural land to the west beyond City limits across Santucci Boulevard.

The proposed project is a 63-unit single-family residential subdivision. The project entitlements include a General Plan Amendment and Specific Plan Amendment for Parcel WB-41 to modify the land use from CC to Medium Density Residential (MDR), a Rezone from CC to Small Lot Residential with Modified Development Standards (RS/DS), and Tentative Subdivision Map to create 63 single-family residential lots on WB-41. A Development Agreement Amendment (DAA) is included to update unit allocations and reflect the land use change.

Subject: Sierra View, WB-31, and WB-41 Water and Sewer Demands Message:

MacKay and Somps is processing a specific plan amendment and general plan amendment for Sierra View, Parcel WB-41 and Parcel WB-31 within the City of Roseville. Sierra View is located south of Diamond Oaks Road and north of Shasta Street. Parcel WB-41 is located south of Pleasant Grove Boulevard, west of Daylight Drive, and east of Santucci Boulevard. Parcel WB-31 is located north of Pleasant Grove Boulevard and east of Santucci Boulevard.

Sierra View is currently designated as a residential land use in the medium density residential (MDR) category and allocates 168 units. Parcel WB-41 is approximately 10.11 acres and is currently designated as commercial (CC) land use. Parcel WB-31 is approximately 11.1 acres and is currently designated as high density residential (HDR) land use with a current allocation of 263 units. This condition is referred to in the tables below as the “Approved Project” The applicant is proposing to change the land uses for these projects as follows:
• Sierra View: 75 low density residential (LDR) units
• Parcel WB-41: 63 (MDR) units
• Parcel WB-31: 293 HDR units
This proposed condition is referred to in the tables below as the “Proposed Project”.

MacKay and Somps has analyzed the changes in sanitary sewer flow and potable water demand based on the proposed land use designations and unit allocations. Table 1 below calculates and compares the sewer flow for the Approved Project and Proposed Project conditions. It has been determined that the proposed changes to the land use designations and unit allocations results in approximately 0.07 MDG less flow.

Table 2 below calculates and compares the total surface water required for the Approved Project and Proposed Project conditions. It has been determined that the proposed changes to the land use designations and unit allocations results in a reduced need for surface water, approximately 2.0 AFY less. These calculations have been confirmed with the City of Roseville in an email exchange dated June 23, 2021.

SVSP EIR MM 4.1-2. Agricultural Conversion Policies
One acre of open space shall be preserved within Placer County for each acre of open space impacted within the Specific Plan area. This is to be accomplished through the recordation of conservation easements that result in the formation of preserve lands (as a “mitigation property or “preserve site” and collectively, “mitigation lands” or “preserve lands”). For the purposes of assessing impacts associated with a specific development project, “open space” impacts shall include all land proposed to be developed for urban uses.

For purposes of mitigation for the specific development project, the term “open space” shall include any and all undeveloped land proposed to be preserved by conservation easement or otherwise required by any governmental agency to be preserved for any reason, specifically including all lands preserved for habitat or agricultural mitigation is required beyond the 1:1 open space requirement noted above, as long as a substantial portion, as determined by the Planning Director, of the mitigation lands acquired are (1) in agricultural production, (2) are undeveloped and have the same or higher value CDC categorization as lands being affected within the Specific Plan property at issue.

In-kind mitigation is not required for agricultural land development within the Specific Plan area.

The City of Roseville shall negotiate in good faith to enter into a fair agreement with Sutter County regarding Sierra Vista’s fair share mitigation for this improvement. In reaching an accommodation with Sutter County, the City and Sutter County, in order to better ensure an effective sub-regional approach to mitigating transportation-related impacts, may choose to include within the same agreements or Joint Powers Authority additional public agencies with whom it must work to mitigate transportation-related impacts, such as Placer County, Sacramento County, and Caltrans. As the City strives to achieve agreement(s) with one or more of these other agencies, the City shall insist that “fair share” fee obligations be reciprocal, in the sense that the other local agencies, in accepting fair share contributions from the SVSP developers, must agree to require new development occurring in their own jurisdictions to make fair share contributions towards mitigation the significant effects of such development on the City’s transportation network. Any such arrangement(s), with just Sutter County or with additional agencies, shall account for existing inter-agency fee programs in order to avoid requiring redundant mitigation or fee payments exceeding fair share mitigation levels. The City intends that its arrangement(s) with Sutter County and any other agencies shall permit the participating agencies flexibility in providing cross-jurisdictional credits and reimbursements consistent with the general “fair share” mitigation standard, and The City and Sutter

require an updated model run incorporating the best available information in order to obtain the most accurate, up-to-date impact assessment feasible and to generate the most accurate, up-to-date estimates of regional fair share contributions. These arrangements, moreover, should also include provisions that allow for periodic updates to the traffic modeling on which fair share payment calculations depend in order to account for (i) newly approved projects cumulatively contributing to transportation-related impacts and that therefore should contribute to the funding of necessary improvements (e.g., the Curry Creek Community Plan in Placer County), (ii) additional physical improvements necessitated in whole or in part by newly approved projects, (iii) changing cost calculations for the construction of needed improvements based on changes in the costs of materials, labor, and other inputs. Implementation of MM 4.3-8 would reduce impacts to a less than significant level; however, these improvements lie outside the jurisdiction of the City of Roseville. As such, this impact is considered significant and unavoidable.

SVSP EIR MM 4.4-1. Dust and Construction Control Policies In accordance with the PCAPCD, the applicant shall comply with all applicable rules and regulations as listed above (e.g., Rule 202, 218 and 228). In addition, at the time of tentative map the applicant(s) shall implement a minimum of five (5) of the following measures unless superseded by state or other more stringent standards:

The following mitigation measures shall be implemented to reduce short-term construction-related air quality impacts. In addition, dust control measures are required to be implemented by all projects in accordance with the City of Roseville Grading Ordinance, and the PCAPCD Fugitive Dust Rule 228. • Applicant shall submit to PCAPCD a Construction Emission / Dust Control Plan within 30 days prior to groundbreaking. If the PCAPCD does not respond within 20 days, the plan shall be considered approved. The plan must address the minimum requirements found in section 300 and 400 of District Rule 228, Fugitive Dust (www.placer.ca.gov/airpollution/a irpolut.htm). The applicant shall keep a hard or electronic copy of Rule 228, Fugitive Dust on-site for reference. • The Construction Emission/Dust Control Plan shall include a comprehensive inventory (i.e. make, model, year, emission rating) of all heavy-duty off-road equipment (50 horsepower (HP) of greater) that will be used an aggregate of 40 or more hours for the construction project.

The plan shall demonstrate that the heavy-duty (> 50 HP) off-road vehicles to be used in the construction project, including owned, leased and subcontractor vehicles, will achieve a project wide fleet-average 20% NOX reduction and 45% particulate reduction compared to the most recent ARB fleet average. PCAPCD shall be contacted for average fleet emission data. Acceptable options for reducing emissions may include use of late model engines, low-emission diesel products, alternative fuels, engine retrofit technology, after-treatment products, and/or other options as they become available. Contractors can access the Sacramento Metropolitan Air Quality Management District’s web site to determine if their off-road fleet meets the requirements listed in this measure (http://www.airquality.org/ceqa/Construction_Mitigation_Calculator.xls).

The following measures are also included to reduce construction-related ROG, Nox, PM10 and PM2.5 emissions:
• All construction equipment shall be maintained in good operating condition.

Contractor shall ensure that all construction equipment is being properly serviced and maintained as per the manufacturer’s specifications. Maintenance records shall be available at the construction site for verification. This measure will reduce combustion emissions of all criteria air pollutants. • Prior to the issuance of any grading permits, all applicants shall submit construction plans denoting the proposed schedule and projected equipment use. Construction contractors shall provide evidence that low emission mobile construction will be used, or that their use was investigated and found to be infeasible for the project. Low emission equipment is defined as meeting the California Air Resources Board’s Tier III standards. Contractors shall also conform to any construction measures imposed by the PCAPCD as well as City Planning Staff. This measure will primarily reduce ROG, Nox, PM10, and PM2.5 exhaust emissions.
• Paints and coating shall be applied either by hand or by high volume, lowpressure spray. This measure will reduce evaporative ROG emissions. • All construction shall comply with the following measures to reduce fugitive dust related emissions of PM10 and PM2.5:
o Maintain a minimum 24-inch freeboard on soil haul trucks or cover payloads using tarps or other suitable means.
o Suspend grading operations during high winds (greater than 15 mph).

a) When feasible, all tree removal shall occur between August 30th and February 15th to avoid the breeding season of any raptor species that could be using the area, and to discourage hawks from nesting in the vicinity of an upcoming construction area.
b) For Swainson’s hawk, if avoidance of tree removal outside the breeding season is not feasible, and a nest is present, the applicants would be required to obtain a 2081 permit from CDFG to mitigate for potential “take” under CESA.

If no nesting is occurring, a take permit would not be required. c) Prior to the beginning of mass grading, including grading for major infrastructure improvements, during the period between February 15th and August 30th, all trees and potential burrowing owl habitat within 350 feet of any grading or earthmoving activity shall be surveyed for active raptor nests or burrows by a qualified biologist no more than 30-days prior to disturbance.

active raptor nests or burrows are found, and the site is within 350-feet of potential construction activity, a highly visible temporary fence shall be erected around the tree or burrow(s) at a distance of up to 350-feet, depending on the species, from the edge of the canopy to prevent construction disturbance and intrusions on the nest area.
d) Preconstruction and non-breeding season exclusion measures shall be developed in consultation with CDFG, and shall preclude burrowing owl occupation of the portions of the project site subject to disturbance such as grading. Burrowing owls may be passively excluded from burrows in construction areas by placing one-way doors in the burrows according to CDFG protocol. The one-way doors must be in place for a minimum of three days. All burrows that may be occupied by burrowing owls regardless of whether they exhibit signs of occupation must be cleared with the one way doors. Burrows that have been cleared through the use of the one-way doors shall then be closed or backfilled to prevent owls from entering the burrow. e) No construction vehicles shall be permitted within restricted areas (i.e., raptor protection zones) unless directly related to the management or protection of the legally protected species.
f) If a legally protected species nest is located in a tree designated for removal, the removal shall be deferred until after August 30th or until the adults and young of the year are no longer dependent on the nest site as determined by a qualified biologist.

Black Rails and Tri-colored Blackbirds
Prior to earth moving that would disturb marsh habitat, a qualified biologist shall conduct surveys to determine the presence of the California black rail. If either of these species is found, all earth moving within 250 feet shall stop and measures, including establishing nest protection buffers along both sides of Curry Creek during the nesting season (generally February 1 through August 31st) shall be implemented.

Rookeries
No heron rookeries are present within the plan area. Prior to earthmoving that would disturb marsh habitat or tree removal of the eucalyptus grove, preconstruction surveys should be conducted to verify that no rookeries have been established. If rookeries are present all earth moving within 250-feet shall stop, during the breeding season.

SVSP EIR MM 4.8-4. Onsite and Offsite Grassland Preservation Swainson’s Hawk
a) CDFG recommends that projects that result in the loss of potential foraging habitat for Swainson’s hawk (which includes grasslands) within 10‐miles of an active nest site provide mitigation for that loss. To the extent feasible, strategies for preserving on‐site grasslands as raptor and migratory bird foraging habitat will be addressed in the Operations and Maintenance Plan prepared pursuant to the Section 404 Permit. Some of these strategies could include; but are not necessarily limited to, grazing for grassland management, monitoring for biological values, and adaptive management. Mitigation for Swainson’s hawk foraging habitat would concurrently mitigate for loss of habitat for a number of other wildlife species in the region such as burrowing owl, red‐tailed hawk, white‐tailed kite, northern harrier, Ferruginous hawk, and logger‐head shrike among others.

Based on information obtained through consultation with CDFG and otherwise, a Swainson’s Hawk Grassland Habitat Mitigation Plan shall be developed to mitigate for the loss of grassland foraging habitat, consistent with the ratios set forth in Table 4.8‐7. Areas within Placer County including the Toad Hill Mitigation Bank, the Western Placer Schools Mitigation Area and a portion of Koshman Ranch and other sites that will be located within Placer County via conservation easements or other mechanisms would provide a total of 1,036 upland/grassland acres. This would reduce the impacts to Swainson’s Hawk to a less than significant level.
[See Table 4.8-8 in SVSP EIR]
Long‐billed Curlew, Burrowing Owls
Mitigation for the Swainson’s hawk would ensure that adequate grassland is preserved at ratios identified in Table 4.8‐7. For foraging within one mile of an active nest, mitigation would be 1:1. Greater than a mile would be at an amount of .75:1. This would set aside adequate grassland that would reduce impacts from loss of grasslands to these species to a less than significant level.

To protect the long term habitat of the stream channels and the WAPA corridor and their potential use by wildlife as movement corridors, the project applicants shall ensure that movement corridors are not obstructed. Through compliance with Section 1600 of the CDFG Code, the applicant(s) will enter into a Streambed Alteration Agreement prior to conducting any construction activities within a stream corridor, which sets forth mitigation measures that the applicant must implement. These measures shall include, but not be limited to; the use of either bridges or culverts that are large enough that wildlife have enough space to pass through road crossings without having to travel over the road surface, the implementation of bank stabilization measures, and/or restoration and revegetation of stream corridor habitat that has been damaged due to the project’s construction. Furthermore, the recreational trails shall be lined by post and rail fence and signage would be used to direct trail users to stay within the designated trail corridor. The trails would be closed after dark and no exterior lighting would be used. Lastly, the implementation of MM 4.8-1 which provides for the conservation of onsite open space along the WAPA corridor and the stream channels would ensure adequate opportunities for wildlife movement through the plan area.

SVSP EIR MM 4.8‐7. Offsite Surveys
Prior to construction of any off- site infrastructure, a qualified biologist shall perform detailed, and if necessary, focused biological surveys of any undisturbed areas that would be affected by infrastructure development.

Because infrastructure for the proposed project would be located in road rightof-way, or undeveloped land similar to the project site, the biological resources that would be expected to occur would not differ substantially from those identified in this EIR. If it is determined that wetland resources or sensitive species would be impacted MM 4.8-1 and MM 4.8-2 shall be implemented, as appropriate to the resource. If it is determined that active nests exist within the off-site improvement location, MM 4.8-3 shall be implemented as appropriate to the species. If it is determined the off-site improvement is located within or adjacent to a wildlife movement corridor, MM 4.8-5 shall be implemented.

during any subsurface development activities, work shall be suspended within 100-feet of the find. The City of Roseville Planning and Public Works Staff shall be immediately notified. At that time, the City of Roseville shall coordinate any necessary investigation of the site with qualified archaeologists as needed, to assess the resource (i.e., whether it is an “historical resource” or a “unique archaeological resource”) and provide proper management recommendations should potential impacts to the resources be found to be significant. Possible management recommendations for important resources could include resource avoidance or, where avoidance is infeasible in light of project design or layout or is unnecessary to avoid significant effects, data recovery excavations. The contractor shall implement any measures deemed feasible and necessary by City staff, in consultation with the archaeologists, to be to avoid or minimize significant effects to the cultural resources. In addition, pursuant to Section 5097.98 or the State Public Resources Code, and Section 7050.5 of the State Health and Safety Code, in the event of the discovery of human remains, the County Coroner shall be immediately notified. If the remains are determined to be Native American, guidelines of the Native American Heritage Commission shall be adhered to in the treatment and disposition of the remains.

The professional archaeologist must make a determination, based on professional judgement and supported by substantial evidence, within one business day of being notified, as to whether or not the find represents a cultural or tribal cultural resource or has the potential to be a cultural or tribal cultural resource. The consulting tribe shall also be given the opportunity to provide, within one business day of being notified, a determination as to whether or not the find represents a tribal cultural resource or has the potential to be a tribal cultural resource. The subsequent actions will be determined by the type of discovery, as described below. These include: 1) a work pause that, upon further investigation, is not actually a discovery and the work pause was simply needed in order to allow for closer examination of soil (a “false alarm”); 2) a work pause and subsequent action for discoveries that are clearly not related to tribal resources, such as can and bottle dumps, artifacts of European origin, and remnants of built environment features; and 3) a work pause and subsequent action for discoveries that are likely related to tribal resources, such as midden soil, bedrock mortars, groundstone, or other similar expressions.

Whenever there is question as to whether or not the discovery represents a tribal resource, culturally affiliated tribes shall be consulted in making the determination. Whenever a tribal monitor is present, the monitor shall be consulted.

The following processes shall apply, depending on the nature of the find, subject to the review and approval of the City:
• Response to False Alarms: If the professional archaeologist determine that the find is negative for any cultural indicators and tribal representatives have not indicated the find is a tribal cultural resource, then work may resume immediately upon notice to proceed from the City’s representative.. No further notifications or archaeological consultation is necessary if it is determined that the discovery is not a cultural or tribal cultural resource of any kind. The professional archaeologist shall provide written documentation of this finding to the City, which shall include as an attachment any written documentation provided by tribal representatives or monitors.

• Response to Non-Tribal Discoveries: If a tribal monitor is not present at the time of discovery and a professional archaeologist determines that the find represents a non-tribal cultural resource from any time period or cultural affiliation, the City shall be notified immediately, to consult on a finding of eligibility and implementation of appropriate treatment measures, if the find is determined to be a Historical Resource under CEQA, as defined in Section 15064.5(a) of the CEQA Guidelines. The professional archaeologist shall provide a photograph of the find and a written description to the City of Roseville. The City of Roseville will notify any [tribe(s)] who, in writing, requested notice of unanticipated discovery of non-tribal resources. Notice shall include the photograph and description of the find, and a tribal representative shall have the opportunity to determine whether or not the find represents a tribal cultural resource. If a response is not received within 24 hours of notification (none of which time period may fall on weekends or City holidays), the City will deem this portion of the measure completed in good faith as long as the notification was made and documented. If requested by a [tribe(s)], the City may extend this timeframe, which shall be documented in writing (electronic communication may be used to satisfy this measure). If a notified tribe responds within 24 hours to indicate that the find represents a tribal cultural resource, then the Response to Tribal Discoveries portion of this measure applies. If the tribe does not respond or concurs that the discovery is non-tribal, work shall not resume within the no-work radius until the City, through consultation as appropriate, determines that the site either: 1) is not a Historical Resource under CEQA, as defined in Section 15064.5(a) of the CEQA Guidelines; or 2) that the treatment measures have been completed to its satisfaction.
• Response to Tribal Discoveries: If the find represents a tribal or potentially tribal cultural resource that does not include human remains, the consulting tribe(s) and City shall be notified. The City will consult with the tribe(s) on a finding of eligibility and implement appropriate treatment

measures, if the find is determined to be either a Historical Resource under CEQA, as defined in Section 15064.5(a) of the CEQA Guidelines, or a Tribal Cultural Resource, as defined in Section 21074 of the Public Resources Code. Preservation in place is the preferred treatment, if feasible. Work shall not resume within the no-work radius until the City, through consultation as appropriate, determines that the site either: 1) is not a Historical Resource under CEQA, as defined in Section 15064.5(a) of the CEQA Guidelines; or 2) not a Tribal Cultural Resource, as defined in Section 21074 of the Public Resources Code; or 3) that the treatment measures have been completed to its satisfaction.
• Response to Human Remains: If the find includes human remains, or remains that are potentially human, the construction supervisor or onsite archaeologist and (if present) tribal monitor shall ensure reasonable protection measures are taken to protect the discovery from disturbance (AB 2641) and shall notify the City and Placer County Coroner (per § 7050.5 of the Health and Safety Code). The provisions of § 7050.5 of the California Health and Safety Code, § 5097.98 of the California Public Resources Code, and Assembly Bill 2641 shall be implemented. If the Coroner determines the remains are Native American and not the result of a crime scene, the Coroner will notify the Native American Heritage Commission (NAHC), which then will designate a Native American Most Likely Descendant (MLD) for the project (§ 5097.98 of the Public Resources Code). The designated MLD will have 48 hours from the time access to the property is granted to make recommendations concerning treatment of the remains. Public Resources Code § 5097.94 provides structure for mediation through the NAHC if necessary. If the landowner does not agree with the recommendations of the MLD, the NAHC can mediate (§ 5097.94 of the Public Resources Code).

If no agreement is reached, the landowner must rebury the remains in a respectful manner where they will not be further disturbed (§ 5097.98 of the Public Resources Code). This will also include either recording the site with the NAHC or the appropriate Information Center; using an open
