Rule 2301
While the Climate Change Action Plan indicated that the GHG emission reduction program would be called the San Joaquin Valley Carbon Exchange, the District incorporated a method to register voluntary GHG emission reductions into its existing Rule 2301-Emission Reduction Credit Banking through amendments of the rule. Amendments to the rule were adopted on January 19, 2012. The purposes of the amendments to the rule include the following:
Provide an administrative mechanism for sources to bank voluntary GHG emission reductions for later use.
Provide an administrative mechanism for sources to transfer banked GHG emission reductions to others for any use.

Local
City of Patterson
The City of Patterson has not yet adopted a Climate Action Plan. However, policies and goals related to climate change are included in the Air Resources and Climate Change Element of the City’s General Plan, adopted on November 30, 2010. General Plan goals and policies relevant to GHG emissions include, but are not limited to, the following:
AR-7.4 Greenhouse gas emissions from new development. The City shall implement measures to reduce the emission of greenhouse gases from new development. Such measures may include, but are not limited to, the following:
Discouraging auto-dependent patterns of development;
Promoting compact, mixed-use, pedestrian-friendly, and transit-oriented development; Promoting energy-efficient building design and site planning using either Build It Green and LEED™ Silver standards for residential and non-residential buildings, respectively; and
Working to improve the ratio of jobs to housing.
3.7.4 - Thresholds of Significance
According to the CEQA Guidelines’ Appendix G Environmental Checklist, to determine whether greenhouse emissions impacts are significant environmental effects, the following questions are analyzed and evaluated. Would the project:
a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
b) Conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases?
c) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? d) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency?
3.7.5 - Methodology
GHG Emissions Generation Calculation Methodology
The emission estimates were developed consistent with the proposed land uses and construction schedule in Chapter 2, Project Description. The California Emissions Estimator Model (CalEEMod) version 2016.3.2 was used to estimate the proposed project’s construction and operation-related

CalEEMod was developed in cooperation with air districts throughout the State and is designed as a uniform platform for government agencies, land use planners, and environmental professionals to quantify potential GHG emissions associated with construction and operation from a variety of land uses.
Construction
Construction emissions can vary substantially from day to day, depending on the level of activity, the specific type of operation, and prevailing weather conditions. Construction-related GHG emissions result from on-site and off-site activities. On-site GHG emissions principally consist of exhaust emissions from heavy-duty construction equipment. Off-site GHG emissions would occur from motor vehicle exhaust from material delivery vehicles and construction worker traffic. However, unlike air quality emissions that have both localized and regional impacts, GHG emissions are evaluated based on the total emissions generated. The construction parameters used to estimate the proposed project’s construction-related GHG emissions were based on CalEEMod default assumptions. Full assumptions are detailed in the CalEEMod modeling output contained in Appendix C.
Operation
Operational GHG emissions are those GHG emissions that occur during operation of the proposed project. The major sources and operational parameters used to estimate the proposed project’s operation-related GHG emissions are summarized below. Full assumptions are detailed in the CalEEMod modeling output contained in Appendix C.
Motor Vehicles
Motor vehicle emissions refer to exhaust and road dust emissions from the automobiles that would travel to and from the project site. The emissions were estimated using CalEEMod. The weekday and Saturday trip generation rates for operations associated with the project were obtained from the transportation impact assessment (included in Appendix C). As weekend trips were not explicitly stated in the transportation impact assessment, weekday trip generation rates were applied to both Saturday and Sunday trips. This presents a conservative analysis because the Saturday and Sunday trip generation rates in the ITE Manual, 10th Edition for mid-rise multi-family housing (ITE Land Use Code 221) are lower than the weekday trip generation rate.
Pass-by trips are made as intermediate stops on the way from an origin to a primary trip destination without a route diversion. Pass-by trips are attracted from traffic passing the project on an adjacent street or roadway that offers direct access to the generator. Pass-by trips are not diverted from another roadway. The CalEEMod defaults pass-by trips were used for this analysis.
The CalEEMod default trip lengths for an urban setting for Stanislaus County were used in this analysis. The vehicle fleet mix is defined as the mix of motor vehicle classes active during the operation of the project. Emission factors are assigned to the expected vehicle mix as a function of vehicle class, speed, and fuel use (gasoline and diesel-powered vehicles). The CalEEMod default vehicle fleet mix for Stanislaus County was used for this analysis.

The use of landscaping equipment (leaf blowers, chain saws, mowers) would generate GHG emissions as a result of fuel combustion based on assumptions in CalEEMod.
Electricity
The project will be served by Turlock Irrigation District. For the purpose of estimating GHG emissions for this analysis, emission factors from Turlock Irrigation District were used. Turlock Irrigation District provides estimates of its emission factor per megawatt hour of electricity delivered to its customers.
Turlock Irrigation District emissions factor for 2017 for CO2 is provided below. The rates for carbon dioxide are based on compliance with the Renewable Portfolio Standard.
Carbon dioxide: 790 lb/MWh
Methane: 0.029 lb/MWh
Nitrous oxide: 0.006 lb/MWh
The factors listed below were applied in estimating emissions for the year 2022.
Carbon dioxide: 519.59 lb/MWh
Methane: 0.029 lb/MWh
Nitrous oxide: 0.006 lb/MWh
SB 350 requires an increase in the amount of electricity procured from renewable energy sources from 33 percent to 50 percent by 2030. Therefore, the adjusted Turlock Irrigation District CalEEMod emission factors are shown below for the year 2030. SB 100 requires utilities to achieve a 60 percent renewable portfolio by 2030. The reductions from SB 100 have not been estimated.
Carbon dioxide: 387.76 pound per megawatt hour (lb/MWh) Methane: 0.022 lb/MWh
Nitrous oxide: 0.005 lb/MWh
CalEEMod has three categories for electricity consumption: Title 24-electricity; non-Title 24- electricity; and lighting. Title 24-electricity uses are defined as the major building envelope systems covered by California’s Building Code Title 24 Part 6, such as space heating, space cooling, water heating, and ventilation. Lighting is separate since it can be both part and not part of Title 24. Since lighting is not part of the building envelope energy budget, CalEEMod does not consider lighting to have any further association with Title 24 references in the program. Non-Title 24-electricity includes everything else such as appliances and electronics. To properly divide the total electricity consumption into the three categories, the percentage for each category is determined by using percentages derived from the CalEEMod default electricity intensity. The percentages are applied to the electricity consumption to obtain the values used in the analysis.

There would be emissions from the combustion of natural gas used for the project (water heaters, heat, etc.). CalEEMod has two categories for natural gas consumption: Title 24-natural gas, and nonTitle 24-natural gas. For purposes of this analysis, CalEEMod defaults were used.
Water and Wastewater
GHG emissions are emitted from the use of electricity to pump water to the project site and to treat wastewater. CalEEMod default values were used in the analysis.
Solid Waste
GHG emissions would be generated from the decomposition of solid waste generated by the project.
CalEEMod was used to estimate the GHG emissions from this source. The CalEEMod default for the mix of landfill types is as follows:
Landfill no gas capture—6 percent;
Landfill capture gas flare—94 percent;
Landfill capture gas energy recovery—0 percent.
Vegetation
Zacharias Master Plan - This planning area contains agricultural land (orchards and row crops).
Baldwin Master Plan - This planning area contains agricultural land (orchards) There is currently some degree of carbon sequestration occurring on-site from existing agriculture.
While the existing landscaping and trees would be removed, the project plan would include 62.7 acres of parks. This would provide on-site carbon sequestration. It was conservatively assumed that the loss and addition of carbon sequestration would be balanced; therefore, emissions due to carbon sequestration were not included.
Life Cycle Emissions
An upstream GHG emissions source (also known as life cycle emissions) refers to emissions that are generated during the manufacturing and transportation of products that would be utilized for construction. Upstream emission sources for construction include but are not limited to GHG emissions from the manufacturing of cement and steel as well as from the transportation of building materials to the seller of such products. The upstream emissions associated with implementation of the project are difficult to estimate because (1) upstream emissions are not within the control of the project and (2) the information is not readily available. Therefore, to characterize these emissions would be speculative, and upstream emissions associated with construction have not been estimated as part of this impact analysis. Additionally, the California Air Pollution Control Officers Association (CAPCOA) White Paper on CEQA and Climate Change supports this approach by stating, “The full life-cycle of GHG emissions from construction activities is not accounted for . . . and the information needed to characterize [life-cycle emissions] would be speculative at the CEQA analysis level.” Therefore, pursuant to CEQA Guidelines Sections 15144 and 15145, upstream/life cycle emissions are speculative, and is not further discussed as part of this impact analysis.

The project is assessed for its consistency with the ARB’s adopted the ARB’s adopted 2017 Climate Change Scoping Plan Update. Consistency would be achieved with an assessment of the project’s compliance with applicable Scoping Plan measures.
Since project buildout will be after 2030, a quantitative assessment was prepared to determine if project emissions at project buildout in 2040 would show reasonable progress toward achieving the State’s 2050 goal of reducing emissions 80 percent below 1990 levels.
3.7.6 - Project Impacts and Mitigation Measures
This section discusses potential impacts associated with the project and provides mitigation measures where necessary.
GHG Emissions Generation
Impact GHG-1: Buildout of the Master Plan would generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment.
Impact Analysis
Threshold of Significance
Section 15064.4(b) of the CEQA Guidelines’ amendments for GHG emissions states that a lead agency may take into account the following three considerations in assessing the significance of impacts from GHG emissions.
Consideration No. 1: The extent to which the project may increase or reduce greenhouse gas emissions as compared to the existing environmental setting.
Consideration No. 2: Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project.
Consideration No. 3: The extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of greenhouse gas emissions. Such regulations or requirements must be adopted by the relevant public agency through a public review process and must include specific requirements that reduce or mitigate the project’s incremental contribution of greenhouse gas emissions. If there is substantial evidence that the possible effects of a particular project are still cumulatively considerable notwithstanding compliance with the adopted regulations or requirements, an EIR must be prepared for the project.
The Master Plan analysis is based on a 20-year buildout with construction being completed in 2040.
The latest legislated GHG reduction targets are from SB 32 with a 2030 target of reducing emissions 40 percent below 1990 levels. The strategy to achieve the 2030 targets is included in the ARB 2017 Scoping Plan. Executive Order S-3-05 includes a goal of reducing emissions by 80 percent below 1990 levels by 2050. Since the project will start construction after the 2020 AB 32 target year, no

The ARB reports that emissions were below the 2020 target level in 2016 and 2017, so it is assumed that emissions will continue to stay below the 2020 target at the end of 2020. Since the project is expected to be completed 10 years after the 2030 target year, consistency is based on progress toward achieving the Governor’s 2050 goal between 2030 and 2050. Achieving the 2050 goal will require an average annual emission reduction of 2.7 percent per year between 2020 and 2050. To maintain this trajectory, the statewide inventory must be reduced by 40 percent by 2030 to 260 MMTCO2e and 53 percent by 2040 to 201 MMTCO2e. The methodology for determining the amount of reductions required as a fair share from development projects to help achieve the targets is discussed below.
The City of Patterson has not adopted its own GHG thresholds or prepared a Climate Action Plan that can be used as a basis for determining project significance, although it has a Sustainability Action Plan, which is a non-qualifying GHG reduction plan. The Valley Air District’s Guidance for Valley Landuse Agencies in Addressing GHG Emission Impacts for New Projects under CEQA includes thresholds based on whether the project will reduce or mitigate GHG levels by 29 percent from BAU levels compared with 2005 levels to achieve the 2020 target, but has not been updated to include targets for 2030 or later. Therefore, this analysis is based on consistency with the SB 32 2030 targets and the 2017 Scoping Plan and progress toward achieving the Governors Executive Order S-3-05 2050 goal.
The use of a reduction from BAU threshold is one approach that can be used if the reduction amount is supported by substantial evidence and accounts for local differences in emission sources and whether new development will provide greater reductions than existing development to comply with the Newhall Ranch Supreme Court decision. A BAU approach for 2030 and beyond has not been developed for the City of Patterson or the San Joaquin Valley; however, the statewide reductions required from development related sources and modeling using local assumptions has been used here as a threshold approach.
The 2017 Scoping Plan strategy for achieving the SB 32 targets would obtain a range of reductions from each emission sector. The plan uses ranges to account for uncertainty in technological advancements and market penetration of lower emitting transportation and energy options. The proposed plan would achieve the bulk of the reductions from Electric Power, Industrial fuel combustion, and Transportation. Cap-and-Trade would provide between 10 and 20 percent of the required reductions depending on the amounts achieved by the other reduction measures. This approach makes determining a community level or a project level target difficult. The GHG emission reductions by Scoping Plan sector are provided in Table 3.7-4.

Emissions from development projects are heavily weighted to transportation/mobile sources and energy use. Mobile sources comprise 59 percent of the project’s 2040 inventory. Energy use comprises 32 percent of the project’s inventory. The remaining sources comprise only 9 percent of the inventory. The reductions from the 1990 inventory estimated in the 2017 Scoping Plan for electric power are 43 to 61 percent and for transportation are 27 to 32 percent in 2030. The percentage reductions from the overall statewide inventory from electricity and transportation are from 56 to 67 percent. Therefore, the largest sources of emissions in development projects will also be subject to the most regulatory measures that are relied upon to achieve the target. The 2017 Scoping Plan includes the following summary of its overall strategy for reaching the 2030 target:
SB 350
- Achieve 50 percent RPS by 2030. (Currently 60 percent with SB 100 RPS revisions) - Doubling of energy efficiency savings by 2030.
Low Carbon Fuel Standard
- Increased stringency (reducing carbon intensity 18 percent by 2030, up from 10 percent in 2020). (Amended by ARB to 20 percent effective January 1, 2019) Mobile Source Strategy (Cleaner Technology and Fuels Scenario) - Maintaining existing GHG standards for light- and heavy-duty vehicles. - Put 4.2 million zero-emission vehicles (ZEVs) on the roads. - Increase ZEV buses, delivery and other trucks.
Sustainable Freight Action Plan
- Improve freight system efficiency.
- Maximize use of near-zero emission vehicles and equipment powered by renewable energy. - Deploy over 100,000 zero-emission trucks and equipment by 2030.

- Declining caps, continued linkage with Québec, and linkage to Ontario, Canada. - ARB will look for opportunities to strengthen the program to support more air quality cobenefits, including specific program design elements. In Fall 2016, ARB staff described potential future amendments including reducing the offset usage limit, redesigning the allocation strategy to reduce free allocation to support increased technology and energy investment at covered entities and reducing allocation if the covered entity increases criteria or toxics emissions over some baseline.
By 2018, develop Integrated Natural and Working Lands Action Plan to secure California’s land base as a net carbon sink.
Work is underway by members of the AEP Climate Change Committee to determine the share of development related emissions included in the 2017 Scoping Plan inventory for use in developing targets for climate action plans and project level analysis. Preliminary results indicate that the development related portion including reductions from Cap and Trade is 158 MMT CO2e per year or a per capita emission amount of 3.6 MT CO2e per person in 2030. The statewide target inventory including all sources is 260 MMT CO2e in the 2030 target year or 5.9 MT CO2e per person. Although the results have not been released, they provide a preliminary number that is used here to illustrate the scale of reductions required. By 2040, the development related inventory will need to decline to 201 MMT CO2e or 2.8 MT CO2e per person to make steady progress toward the 2050 goal. The Baldwin / Zacharias Master Plans include residential, commercial, and industrial uses providing a mix of development that is comparable to those in statewide development inventory. Therefore, a threshold based on achieving reductions less than or equal to the per capita rate required to achieve the SB 32 target and to make reasonable progress toward achieving the 2050 goal by 2040 would provide a valid quantitative threshold when used in conjunction with additional qualitative analysis for consistency with the 2017 Scoping Plan.
The California Supreme Court in the Newhall Ranch decision was concerned that new development may need to do more than existing development to reduce GHGs to demonstrate that it is doing its fair share of reductions. As will be shown below, new development does do more than existing development and, due to the nature of the sources of GHG emissions related to development, existing development is equally responsible for reducing emissions from the most important sources of emissions. It is important to note that most of the State’s regulatory program applies to new and existing development.
The State’s regulatory program is able to target both new and existing development because the two most important strategies—motor vehicle fuel efficiency and emissions from electricity generation— obtain reductions equally from existing and new development. This is because all vehicle operators

This includes regulations on mobile sources such as: The Pavley standards that apply to all vehicles purchased in California, the LCFS that applies to all fuel used in California, and the Renewable Portfolio Standard and Renewable Energy Standard that apply to utilities providing electricity to all California homes and businesses. The reduction strategy where new development is required to do more than existing development is building energy efficiency and energy use related to water conservation regulations. For example, new projects are subject to Title 24 Energy Efficiency standards and CALGreen Code and Model Water Efficient Landscape Ordinance (MWELO) water conservation requirements. Residential buildings constructed to the 2013 Title 24 standards use 25 percent less energy than buildings complying with the 2008 standards. 2016 Title 24 improved energy efficiency in residential buildings by 28 percent compared to the 2013 Title 24 standards and 46 percent compared with 2008 Title 24 standards. New buildings and landscapes are much more energy efficient and water efficient than the development that has been built over the past decades and will require much less energy. The 2019 Title 24 standards which became effective in January 2020 makes progress toward achieving net zero energy use through requirements for onsite renewable generation for most projects. The project buildings would be constructed after 2020 and would be required to comply with 2019 Title 24 standards. Additional reductions can be expected with next versions of Title 24 until net zero energy use is achieved.
The project analysis also includes a qualitative assessment of compliance with Scoping Plan strategies to support GHG significance findings under Impact GHG-2. There are no measures that identify specific requirements on development projects, but the analysis shows how the applicable measures affect project emission sources.
Construction
Total GHG emissions generated during all years of construction were estimated using CalEEMod 2016.3.2 and are presented in Table 3.7-4. Construction emissions were assessed based on annual average construction activity for the residential and commercial/industrial land use categories.
Separate model runs were prepared for the schools and parks since they are discrete projects and not spread out over the 20-year buildout. The annual average construction activity for residential, commercial and industrial was modeled for the year 2021 and the results were multiplied by 20 to reflect the 20-year buildout period at a steady rate of construction. The schools and parks were modeled for years 2022, and 2024. Using a model year early in the buildout period is a conservative assumption because emissions are expected to decrease as old construction equipment is replaced with new cleaner equipment. The Valley Air District does not recommend assessing the significance of construction-related GHG emissions. Any construction-related emissions would be temporary.
However, other jurisdictions such as the South Coast Air Quality Management District (SCAQMD) and the Sacramento Metropolitan Air Quality Management District (SMAQMD) have concluded that construction emissions should be included since they may remain in the atmosphere for years after construction is complete. Therefore, the amortized construction-related GHG emissions have been added to the operational emissions for determining significance.

CalEEMod assumes compliance with some, but not all, applicable rules and regulations regarding energy efficiency, vehicle fuel efficiency, renewable energy usage, and other GHG reduction policies. The reductions obtained from each regulation and the source of the reduction amount used in the analysis are described below.
Emissions Accounting for Applicable Regulations
The following regulations are incorporated into the CalEEMod emission factors:
Pavley I and Pavley II (LEV III) motor vehicle emission standards ARB Medium and Heavy-Duty Vehicle Regulation
2005, 2008, 2013, and 2016 Title 24 Energy Efficiency Standards The following regulations have not been incorporated into the CalEEMod emission factors and require alternative methods to account for emission reductions provided by the regulations:
Renewable Portfolio Standards
Low Carbon Fuel Standard
Green Building Code Standards (indoor water use)
California Model Water Efficient Landscape Ordinance (Outdoor Water) Pavley II/LEV III standards have been incorporated in the latest version of CalEEMod. ARB estimates a 3 percent reduction in 2020 and a 19 percent reduction from the vehicle categories subject to the regulation by 2030.
The ARB GHG Regulation for Medium and Heavy-Duty Engines and Vehicles applies to trucks that will be accessing the project site. The benefits of the regulation were incorporated into CalEEMod 2016.3.2. The ARB estimates that this regulation will reduce GHG emissions from the affected vehicles by 7.2 percent.
The LCFS is estimated to achieve a 10 percent reduction in emissions by 2020 and a 20 percent reduction by 2030. CalEEMod does not include credit for the LCFS.
Title 24 reductions for 2013 and 2016 updates were added to CalEEMod 2016.3.2. The CEC estimates that 2013 Title 24 standards would result in an increase in energy efficiency of 25 percent in residential buildings compared to 2008 Title 24. An additional 28 percent reduction from the 2008 standards have been claimed for compliance with 2016 Title 24. This results in a combined reduction of 46 percent. Compliance with 2019 Title 24 is expected to reduce residential energy use by 7 percent beyond 2016 Title 24. 2019 Title 24 requires new residential development include solar panels to generate electricity. The project will include solar panels on each residential unit in

Non-residential projects would achieve a reduction electricity of 10.7 percent and natural gas of 1 percent compared to the 2016 standards.
RPS is not accounted for in CalEEMod 2016.3.2. Reductions from RPS are addressed by revising the electricity emission intensity factor in CalEEMod to account for the utility RPS rate forecast for 2030 to meet the 50 percent mandate. Utilities will be required by SB 100 to increase the use of renewable energy sources to 60 percent by 2030, but details on individual utility compliance have not been determined.
Energy savings from water conservation resulting from the Green Building Code Standards for indoor water use and California Model Water Efficient Landscape Ordinance for outdoor water use are not included in CalEEMod. The Water Conservation Act of 2009 mandates a 20 percent reduction in urban water use that is implemented with these regulations. Benefits of the water conservation regulations are applied in the CalEEMod mitigation component.
Reductions in emissions from solid waste are based on the City achieving the CalRecycle 75 Percent Initiative by 2020 compared with a 50 percent baseline for 2005. Reductions are taken using the CalEEMod mitigation component.
Regulations applicable to project sources and the percent reduction anticipated from each source are shown in Table 3.7-6. The percentage reductions are only applied to the specific sources subject to the regulations. For example, the Pavley Low Emission Vehicle Standards apply only to light duty cars and trucks.

It is important to note that reductions listed in Table 3.7-6 do not include new strategies proposed in the 2017 Scoping Plan Update. The plan was adopted in December 2017. The plan provides alternatives in terms of their likelihood of implementation and ranges of reduction from the strategies. Measures already authorized by legislation are highly likely to be implemented, while measures requiring new legislation are less likely to go forward. The State is highly likely to incorporate zero net energy buildings in future updates to Title 24 and now requires solar panels in most residential development. A new round of motor vehicle fuel efficiency standards beyond 2025 when LEV III standards are at their maximum reduction level is highly likely. Changing heavy-duty trucks and off-road equipment to alternative fuels face greater technological hurdles and are less likely to provide dramatic reductions by 2030. Reductions from achieving 60 percent RPS by 2030 have not been included in this analysis.
In addition to rules and regulations, the project will provide design features and infrastructure encouraged by General Plan policies and City of Patterson design standards that would reduce project vehicle miles traveled compared to default values. Note that CalEEMod nominally treats these design elements and conditions as “mitigation measures,” despite their inclusion in the project description. Therefore, reported operational emissions are considered to represent unmitigated project conditions.

These include residential, commercial/industrial, elementary school, middle school, and parks. The model runs for residential and commercial/industrial reflect the cumulative project buildout in 2040. The model runs for the schools and parks were run as discrete projects with a 2040 operation year to match the buildout year for the entire project. An additional run for only the Baldwin Master Plan was run for information only. The emissions for each component were added to determine the total emissions at buildout from all Master Plan land uses.

The results include CalEEMod reductions for site design measures that provide credit for location near employment centers and for pedestrian infrastructure.
It is currently speculative to quantify the emissions savings from future regulatory measures, as they have not yet been developed; however, it can be anticipated that during the 20 year buildout period, regulations will be adopted to implement the 2017 Scoping Plan and another Scoping Plan is likely to be developed to achieve post-2030 targets. The City has no regulatory authority over the largest project source (motor vehicles); however, the project design features supporting multimodal travel such as bike paths, pedestrian connections, and transit service will result in decreases in VMT consistent with SB 375 requirements for 2035. New residences located within the Master Plan will be near net zero electricity use to comply with 2019 Title 24 standards when reductions from solar panels is included. Nonresidential projects constructed after 2030 are likely to be constructed to near net zero standards. Additional reductions will be achieved when the electric utility achieves the 60 percent RPS mandate in 2030. The amount of reductions attributable to the project from these regulations has not been determined; therefore, project GHG emissions may exceed the per capita threshold for 2040.
The operational emissions associated with the Baldwin Master Plan are provided in Table 3.7-9. The Baldwin project includes only residential development, so emissions from commercial and industrial uses are not included. This result is lower per capita emissions compared to the full project.

The Scoping Plan does not define all feasible measures or attribute an amount of reductions required from new development beyond compliance with regulations. When requiring mitigation of a project’s fair share of a cumulative impact, the Lead Agency must show the nexus between the project contribution and its fair share of mitigation to reduce the impact to less than cumulatively considerable.
The following discussion assesses the feasibility of mitigation considered for the project. Measures must exceed the amounts required by regulation in order to be considered mitigation, but for a project that has a 20-year buildout schedule, new and modified regulations applicable to project emission sources can be expected throughout the development timeframe. This creates a conflict between requirements to mitigate significant impacts to the extent feasible and requirements to mitigate only a fair share of the impact. Mitigation measures requiring projects to exceed energy efficiency standards by a certain percentage become obsolete quickly when the standards are revised every three years. Adopted standards are generally superior to mitigation measures because they are supported by technical analysis and a public review process to determine feasibility and fairness. Project mitigation measures are often applied with limited review for feasibility or by requiring applicants to prove infeasibility. When there is a well-established regulatory program in place that is intended to address the impact, going beyond the regulation circumvents the regulatory process and becomes regulation by mitigation. Therefore, no energy efficiency mitigation beyond Title 24 and the CalGreen Building Code has been included in the project.
For large Master Plans and General Plan updates it is common to rely on goals and policies to mitigate significant impacts on a programmatic basis. The 2010 General Plan includes goals and policies related to climate change that will help reduce project impacts. In addition, the City of Patterson Community Design Guidelines help ensure that projects are designed in ways that support walking, and bicycling, provide well connected streets, and provide site orientation to optimize passive solar heating and lighting and that optimizes solar energy installations. Additional design guidelines address water conservation, parking, and use of neotraditional design. By following the Design Guidelines, project implementing the Baldwin / Zacharias Master Plan will be applying the measures suggested by the 2017 Scoping Plan for land use projects. Mitigation Measure (MM) TRANS-2 requires that Transportation Demand Management measures be assessed and implemented as development occurs pursuant to the Master Plan which includes things such as pedestrian, bicycle, and transit facilities.
The project is assumed to use natural gas for space and water heating purposes. The 2017 Scoping Plan indicates that increased use of electricity for heating will be required to meet net zero energy goals. Mandating electricity for heating is best addressed through a statewide regulatory process that provides uniform standards and timelines for implementation for all development rather than as a mitigation measure.
Large industrial and commercial projects that employ more than 100 persons with arrival times during peak traffic hours are subject to Valley Air District Rule 9410 Employer Based Trip Reduction.
Employers are required to implement an Employer Trip Reduction Implementation Plan (ETRIP) for each worksite and to meet the applicable point targets specified in the Rule. Measures such as ride share programs, transportation demand management programs, on-site facilities to encourage the

Compliance with this rule will reduce GHG emissions from commute trips. MM TRANS-2 requires that Transportation Demand Management measures be assessed and implemented as development occurs pursuant to the Master Plan consistent with ETRIP.
Another potential mitigation option is to require developers to purchase carbon offsets to reduce emissions to less than significant levels. Carbon offset markets are being established with programs such as the Climate Action Reserve. The cost of carbon offsets is subject to market forces and the cost to develop and maintain offset projects. Projects with approved protocols include forestry, and livestock methane capture. The Master Plan would likely be developed by multiple developers over the 20-year buildout period. Each project would require its own analysis to determine its fair share of the mitigation requirement and procedures for tracking and monitoring implementation. The City and most developers do not have resources to manage such a program. In addition, as discussed earlier, the amount of mitigation required would vary depending on reductions achieved by new regulations. Requiring developers and future residents and businesses to further mitigate emissions without accounting for compliance with regulations would result in double mitigation, first by the developer and then by the residents and businesses purchasing electricity, fuel, and vehicles compliant with regulations in effect at the time of purchase and beyond that would violate constitutional nexus requirements.
In conclusion, project emissions from development prior to 2030 would not achieve the emission reduction requirements to demonstrate consistency with the 2017 Scoping Plan targets for 2030. In addition, the project would exceed the per capita threshold for development related emissions needed to demonstrate sufficient progress toward the Governor’s 2050 goal by project buildout in 2040. The development related per capita emission target for 2040 is 2.79 MT CO2e per person compared to the project per capita emissions project per capita emissions are 5.85 MT CO2e.
Mitigation measures to reduce the impact to below the threshold are not feasible. Therefore, this impact is considered significant and unavoidable.

Potentially significant impact.

Impact Analysis
The City of Patterson has not adopted a GHG reduction plan or Climate Action Plan. In addition, the City has not completed the GHG inventory, benchmarking, and goal-setting process required to identify a reduction target and to take advantage of the streamlining provisions contained in the CEQA Guidelines amendments adopted for SB 97. The Valley Air District has adopted a Climate Action Plan, but it does not contain measures that are applicable to development projects.
Therefore, the Valley Air District Climate Action Plan cannot be applied to the project. Since no other local or regional Climate Action Plan is in place, the project is assessed for its consistency with ARB’s adopted Scoping Plan. This would be achieved with an assessment of the project’s compliance with Scoping Plan measures.
Scoping Plan
The California State Legislature adopted AB 32 in 2006 which included a goal of reducing emissions to 1990 levels by 2020. The 2008 Scoping Plan provided a strategy for achieving the AB 32 target.
The California GHG emission inventory was below the target in 2016 and 2017 and is expected to stay below the target in the 2020 milestone year. The project would begin construction after 2020; therefore, the 2008 Scoping Plan is not applicable to the project. The 2017 Scoping Plan Update provides the State’s strategy to achieve the SB 32 target of reducing GHG emissions by 40 percent below 1990 levels by 2030. The following consistency analysis applies to the 2017 Scoping Plan and later State goals.
Consistency with California’s Post-2020 Targets
The State’s executive branch adopted several Executive Orders related to GHG emissions. Executive Orders S-3-05 and B-30-15 are two examples. Executive Order S-3-05 sets goals to reduce emissions to 1990 levels by 2020 and 80 percent below 1990 levels by 2050. The goal of Executive Order S-3-05 to reduce GHG emissions to 1990 levels by 2020 was codified by AB 32. The project will be constructed after the 2020; therefore, the project does not conflict with this component of Executive Order S-3-05. Executive Order B-30-15 establishes an interim goal to reduce GHG emissions to 40 percent below 1990 levels by 2030.
The 2030 goal was codified under SB 32 and is now addressed by the 2017 Scoping Plan Update. The new plan provides a strategy that is capable of reaching the SB 32 target if the measures included in the plan are implemented and achieve reductions within the ranges expected. Under the Scoping Plan Update, local government plays a supporting role through its land use authority and control over local transportation infrastructure. The 2017 Scoping Plan includes reductions from implementation of SB 375 that applies to VMT from passenger vehicles. Stanislaus County targets for SB 375 are a 5 percent reduction by 2020 and a 10 percent reduction by 2035. SB 375 is implemented with the StanCog Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). The RTP/SCS envisions an increase in development density that would encourage fewer

The Executive Order S-3-05 2050 target has not been codified by legislation. Studies have shown that, in order to meet the 2050 target, aggressive pursuit of technologies in the transportation and energy sectors, including electrification and the decarbonization of fuel, will be required. Because of the technological shifts required and the unknown parameters of the regulatory framework in 2050, quantitatively analyzing the project’s impacts further relative to the 2050 goal is speculative for purposes of CEQA (ARB 2014b).
AB 32 and now SB 32 established an emissions reduction trajectory that will allow California to achieve the more stringent 2050 target: The greenhouse gas emission reduction measures contained in the 2008 and 2017 Scoping Plans indicate that they put the State on a path to meet the long-term 2050 goal of reducing California’s GHG emissions to 80 percent below 1990 levels on a trajectory consistent with the reductions that are needed globally to stabilize the climate. Many of the emission reduction strategies adopted to achieve the AB 32 targets will continue to provide reductions that will help achieve the post-2020 targets:
Energy Sector: Continued improvements in California’s appliance and building energy efficiency programs and initiatives, such as the State’s zero net energy building goals, would serve to reduce the proposed project’s emissions level. Additionally, further additions to California’s renewable resource portfolio would favorably influence the project’s emissions level.
Transportation Sector: Anticipated deployment of improved vehicle efficiency, zero emission technologies, lower carbon fuels, and improvement of existing transportation systems all will serve to reduce the project’s emissions level.
Water Sector: The project’s emissions level will be reduced as a result of further desired enhancements to water conservation technologies.
Waste Management Sector: Plans to further improve recycling, reuse and reduction of solid waste will beneficially reduce the project’s emissions level.
For the reasons described above, the project’s emissions trajectory is expected to follow a declining trend, consistent with the 2030 and 2050 targets.

Source: ARB 2017 Scoping Plan Update (ARB 2017c)
Further, recent studies show that the State’s existing and proposed regulatory framework will allow the State to reduce its GHG emissions level to 40 percent below 1990 levels by 2030, and to 80 percent below 1990 levels by 2050. Even though these studies did not provide an exact regulatory and technological roadmap to achieve the 2030 and 2050 goals, they demonstrated that various combinations of policies could allow the statewide emissions level to remain very low through 2050, suggesting that the combination of new technologies and other regulations not analyzed in the studies could allow the State to meet the 2050 target (Energy and Economics 2015).
Given the proportional contribution of mobile source-related GHG emissions to the State’s inventory, recent studies also show that relatively new trends—such as the increasing importance of web-based shopping, the emergence of different driving patterns by the “millennial” generation, and the increasing effect of web-based applications on transportation choices—are beginning to substantially influence transportation choices and the energy used by transportation modes. These factors have changed the direction of transportation trends in recent years and will require the creation of new models to effectively analyze future transportation patterns and the corresponding effect on GHG emissions. For the reasons described above, the proposed project’s post-2020 emissions trajectory through its 2040 buildout is expected to follow a declining trend, consistent with the SB 2030 target and 2050 goal.

Fuels Scenario) Vehicle manufacturers will be
required to meet existing regulations mandated by
the LEV III and Heavy-Duty Vehicle programs. The
strategy includes a goal of having 4.2 million ZEVs on
the road by 2030 and increasing numbers of ZEV
trucks and buses.
Consistent. Project residents and businesses can be
expected to purchase increasing numbers of more
fuel efficient and zero emission cars and trucks each
year. The 2016 CALGreen Code requires electrical
service in new single-family housing and commercial
projects to be EV charger-ready. Home deliveries will
be made by increasing numbers of ZEV delivery
trucks.
Sustainable Freight Action Plan The plan’s target is to improve freight system efficiency 25 percent by
increasing the value of goods and services produced
from the freight sector, relative to the amount of
carbon that it produces by 2030. This would be
achieved by deploying over 100,000 freight vehicles
and equipment capable of zero emission operation
and maximize near-zero emission freight vehicles and
equipment powered by renewable energy by 2030.
Not Applicable. The measure applies to owners and
operators of trucks and freight operations. However,
home and business deliveries are expected to be
made by increasing number of ZEV delivery trucks.
Short-Lived Climate Pollutant (SLCP) Reduction
Strategy. The strategy requires the reduction of
SLCPs by 40 percent from 2013 levels by 2030 and
the reduction of black carbon by 50 percent from
2013 levels by 2030.
Consistent. The project will include only natural gas
hearths that produce very little black carbon
compared to woodburning fireplaces and heaters.
Businesses with large refrigeration systems are
subject the ARB Refrigeration Management Program.
SB 375 Sustainable Communities Strategies.
Requires Regional Transportation Plans to include a
sustainable communities strategy for reduction of per
capita vehicle miles traveled. The targets for Fresno
County are
Consistent. The project will provide residential
development and jobs in the region that is consistent
with the Regional Transportation Plan/Sustainable
Communities Strategy (SCS) strategy to increase
development densities to reduce VMT. The project is
not within an SCS priority area and so is not subject
to requirements applicable to those areas.

The Cap-and-Trade Program covers the GHG emissions
associated with electricity consumed in California,
whether generated in-state or imported. Accordingly,
GHG emissions associated with CEQA projects’
electricity usage are covered by the Cap-and-Trade
Program. The Cap-and-Trade Program also covers fuel
suppliers (natural gas and propane fuel providers and
transportation fuel providers) to address emissions
from such fuels and from combustion of other fossil
fuels not directly covered at large sources in the
program’s first compliance period.
Natural and Working Lands Action Plan. The ARB is
working in coordination with several other agencies
at the federal, state, and local levels, stakeholders,
and with the public, to develop measures as outlined
in the Scoping Plan Update and the governor’s
Executive Order B-30-15 to reduce GHG emissions
and to cultivate net carbon sequestration potential
for California’s natural and working land.
Not Applicable. The project includes residential and
nonresidential development and will not be
considered natural or working lands.
Source: ARB 2017 Scoping Plan Update.
Regarding the goal for 2050 under Executive Order S-3-05, at this time it is premature to provide analysis specifically for this milestone. However, the project analysis assesses the progress needed by the 2040 project buildout year to be on track to achieving the 2050 goal. As was discussed earlier, it is not possible to quantify the benefits of strategies that are yet to be adopted. The 2017 Scoping Plan provides the first step toward achieving longer term goals with its 2030 targets and well-developed regulatory strategy supported by legislation that will help ensure that the required measures are implemented. Legislative action to mandate a 2040 or 2050 target and additional Scoping Plans to address post-2030 targets will be needed to ensure progress continues.
Although the project is consistent with 2017 Scoping Plan measures, the project would not be consistent with the 2030 targets for the portions of the project that would be built by 2030 and could conflict with implementation of the 2017 Scoping Plan if sufficient regulations implementing the 2017 Scoping Plan are not adopted to achieve the 2030 target. In addition, based on the analysis of per capita project emissions at buildout in 2040, the GHG reductions achieved by project design features and compliance with applicable regulations would not be sufficient to show steady progress toward the 2050 goal. In the First Scoping Plan Update; however, ARB generally described the type of activities required to achieve the 2050 target: “energy demand reduction through efficiency and activity changes; large scale electrification of on-road vehicles, buildings, and industrial machinery; decarbonizing electricity and fuel supplies; and rapid market penetration of efficiency and clean

It is not possible to predict the course of future legislative action on climate change. Therefore, the project may be considered inconsistent with achieving the 2050 goal. Feasible measures are not available for the project to reduce emissions to the levels required by 2040. Therefore, this impact is considered significant and unavoidable.
Level of Significance Before Mitigation
Potentially significant impact.
Mitigation Measures
Implement Mitigation Measure TRANS-2.
Level of Significance After Mitigation
Significant and unavoidable.
Energy
Impact GHG-3: Buildout of the Master Plans would not result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation.
Impact Analysis
Appendix F of the CEQA Guidelines applies to the direct and indirect impact analysis, as well as the cumulative impact analysis. Appendix F does not prescribe a threshold for the determination of significance. Rather, Appendix F focuses on reducing and minimizing inefficient, wasteful, and unnecessary consumption of energy. Therefore, for the purposes of this EIR, a significant impact to energy would result if the project would:
1. Result in the wasteful and inefficient use of nonrenewable resources during its construction.
2. Result in the wasteful and inefficient use of nonrenewable resources during long-term operation.
3. Be inconsistent with Adopted Plans and Policies.
Construction Energy Consumption
Project construction is assumed to take 20 years to complete. Construction activities would consume energy through the operation of heavy off-road equipment, trucks, and worker traffic. Construction equipment fuel consumption for each of was based on equipment lists generated using CalEEMod default values. The construction equipment quantities and types are CalEEMod values for each type of development in the Master Plan. The fuel consumption of off-road equipment calculated in this analysis is based on a SCAQMD estimated fuel consumption rate of 0.05 gallons per horsepower hour and the horsepower, usage hours, and load factors from CalEEMod model runs prepared for the project’s air quality analysis.

Worker, vendor, and haul trips would result in approximately 3,056,220 VMT over the entire construction period. A countywide average fuel consumption of 21.1 mpg obtained from EMFAC 2017 was used to determine fuel consumption from worker, vendor, and haul trips. As a result, construction worker, vendor, and haul trips would consume approximately 144,845 gallons of motor vehicle fuel during the entire 20 years of construction.
Although the proposed project would result in the consumption of an estimated 534,755 gallons of diesel and 144,845 gallons of motor vehicle fuels during construction, the project is expected at to achieve energy efficiencies typical for residential and non-residential projects in California.
Construction equipment fleet turnover and increasingly stringent state and federal regulations on engine efficiency combined with local, state, and federal regulations limiting engine idling times and require recycling of construction debris, would further reduce the amount of transportation fuel demand during project construction. Considering these reductions in transportation fuel use, the proposed project would not result in the wasteful and inefficient use of energy resources during construction and impacts would be less than significant. Detailed modeling results are provided in Appendix C.
Operation Energy Consumption
Long-term energy consumption associated with the project includes electricity and natural gas consumption by residents and the commercial and industrial portions of the project. Energy is also used for water conveyance, and long-term vehicle operations from residents and businesses.
Electricity and Natural Gas Consumption
During operations the proposed project would consume natural gas for space heating, water heating, and cooking associated with the land uses on the project site. The natural gas consumption was estimated for each of the project’s land uses based on the CalEEMod default values. The results of the analysis indicate that the project would consume approximately 196,852,440 thousand British thermal units (kbtu) per year of natural gas per year during operation.
In addition to the consumption of natural gas, the proposed project would use electricity for lighting, appliances, and other uses associated with the project’s land uses. Electricity use during operations was estimated using CalEEMod default values for project’s specific land uses. The results of the modeling indicate that the project would use approximately 142,260,106 kilowatt-hours (kWh) of electricity per year. 2019 Title 24 requires the installation of solar panels in residential developments. The amount installed can vary due to local conditions and project design. In addition, some projects may use community solar installations instead of roof top solar. Although, the energy estimates assume no solar will be installed, most electricity used by the residential portions of the project is expected to be generated by zero emission renewable sources. Non-residential projects are not currently subject to mandatory solar installations; however, the State’s goal is for nonresidential development to be net zero energy consumption by 2030.

However, the project would be designed to meet the most recent Title 24 standards. Title 24 specifically establishes energy efficiency standards for residential and non-residential buildings constructed in the State of California in order to reduce energy demand and consumption. Title 24 is updated periodically to incorporate and consider new energy efficiency technologies and methodologies. Therefore, impacts from the wasteful or inefficient use of electricity or natural gas during operation of the project would be less than significant.
Water Treatment, Conveyance, and Distribution
Water used for indoor and outdoor purposes requires electricity for water treatment, conveyance, and distribution. The project’s water demand was calculated based on default values for the specific land uses proposed by the project using CalEEMod. Based on this methodology the proposed project is estimated to use approximately 1,650 million gallons of indoor water per year as well as 278 million gallons of outdoor water per year. This would result in the use of approximately 6,748,120 kWh of electricity per year.
Although the proposed project would result in electricity use from the treatment, conveyance, and distribution of water to the project site, the project would also require all water fixtures to be compliant with the 2013 California Green Building Standards Code and the MWELO, which would reduce the amount of water used by the project and require compliance with regulations relating to drought conditions. Therefore, the project would not result in the wasteful or inefficient use of electricity for water treatment, conveyance, and distribution and impacts would be less than significant.
Wastewater Service
The project would be served by the City of Patterson Wastewater Treatment Facility (WWTF). Project wastewater generation was estimated using CalEEMod default assumptions for indoor water use required by the project land uses. Project indoor water use of 1,650 Mgal per day would result in the use of 3,153,813 kWh of electricity per year. Compliance with the 2013 California Green Building Standards Code, would reduce the wastewater generated by the project. Energy used for treating project wastewater will increasingly be generated by renewable energy sources to comply with RPS standards that apply to the energy utility serving the project area.
The project site and the entire City of Patterson are nearly flat, but slope in the direction of the WWTF. The elevation at the project site is approximately 113 feet and the elevation at the WWTF is approximately 53 feet. This is expected to limit the need to pump wastewater to a great extent since gravity will do most of the work in moving the effluent. The WWTF would uses standard treatment equipment that would not result in wasteful energy use. Any new facilities that are needed to accommodate the project would be required to meet the latest standards and technologies.
Wastewater service would require an extension of sewer lines to the treatment plant. The energy added for the extension and use of these facilities combined with the project’s estimated electricity and natural gas consumption would not result in substantial new energy generation or transmission infrastructure due to the location and capacity of existing energy infrastructure near the project site.

Therefore, the project would not result in the wasteful or inefficient use of electricity for wastewater treatment, and impacts would be less than significant.
Fuel Consumption
During operation of the proposed project vehicle trips would be generated by the project’s specific land uses. The project’s specific land uses were modeled in CalEEMod using ITE 10th Edition vehicle trip generation rates. As shown in Appendix C, the vehicle trips generated would result in approximately 233,894,978 VMT per year. Based on a countywide average fuel consumption of 21.1 mpg from Emission Factor (EMFAC) 2017 for all vehicle classifications for 2022, the proposed project would result in the consumption of an estimated 11,085,070 gallons per year of transportation fuel.
Various federal and state regulations including the Low Carbon Fuel Standard, Pavley Clean Car Standards, and Low Emission Vehicle Program would serve to reduce the project’s transportation fuel consumption progressively into the future. Therefore, the project would be designed to avoid the wasteful and inefficient use of transportation fuel during operations and impacts would be less than significant.
State and federal regulatory requirements addressing fuel efficiency are expected to increase fuel efficiency over time as older, less fuel-efficient vehicles are retired. The efficiency standards and light/heavy vehicle efficiency/hybridization programs, contribute to increased fuel efficiency and therefore would reduce vehicle fuel energy consumption rates over time. The annual vehicular energy consumption calculated for the proposed project was based on 2022 average rates for Stanislaus County. This is considered a conservative estimate because rates are expected to decline significantly by project buildout in 2040. While the project would increase the consumption of gasoline and diesel proportionately with projected population and employment growth, the increase would be accommodated within the projected growth as part of the energy projections for the state and the region and would not require the construction of new regional energy production facilities.
Therefore, energy impacts related to fuel consumption/efficiency during project operations would be less than significant.
As described above, the project would result in less than significant impacts on the wasteful, inefficient, or unnecessary use of energy due to project design features that will comply with the City’s design guidelines and regulations that apply to the project such as Title 24 Building Energy Efficiency Standards and the California Green Building Standards Code that apply to commercial and residential buildings. These regulations are expected to become increasingly stringent over time and would require the project to minimize the wasteful and inefficient use of energy. Furthermore, various federal and state regulations including the Low Carbon Fuel Standard, Pavley Clean Car Standards, and Low Emission Vehicle Program would serve to reduce the transportation fuel demand by Master Plan projects.
With the adherence to the increasingly stringent building and vehicle efficiency standards as well as implementation of the project’s design features that would reduce energy consumption, the proposed project would not contribute to a cumulative impact to the wasteful or inefficient use of energy. As such, the project would not result in a significant environmental impact due to wasteful,

Impact Analysis
Be Inconsistent with Adopted Plans and Policies
The City of Patterson Sustainability Plan (City of Patterson 2009), prepared in 2009, provides energy goals of and policies for the community. The Patterson Sustainability Plan sets forth specific actions to improve City’s overall sustainability now and in the future. It recommends specific changes to the City’s current operational and decision-making practices, as well as changes the private sector can make (voluntary or otherwise). The objective of the Plan is to preserve the unique character and quality of life in Patterson, minimize adverse environmental impacts, and promote efficient use of land, materials, energy, water, and other finite resources. The Sustainability Plan includes the following goals and policies:
1. Reduce energy use (e.g. electricity, gas) in buildings.
2. Integrate energy efficiency into standard operating procedures for government, residents, and commercial and industrial businesses.
3. Strive to meet all new demand through energy efficiency and renewable energy sources.
4. Increase the amount of on-site renewable energy projects in Patterson.
Goal EE-1: Incorporate sustainable building practices into the City’s development regulations.
Actions
EE-1.1: By 2010, adopt a mandatory Green Building Ordinance for new construction and renovation. a. Require Build It Green’s GreenPoint Rated certification for residential construction and a LEED Silver rating for healthcare facilities and commercial & industrial construction. b. Offer flexibility and options to the property owner in determining which materials and techniques meet their needs and desires for complying with the standards.
EE-1.2 Encourage passive solar design (passive heating and cooling) to avoid or minimize cooling needs through building orientation of all new development.
EE-1.3 Amend Municipal Code to allow more flexible development standards as incentives for development projects that exceed the minimum requirements for LEED or GreenPoint Rated, such as density bonuses, increased maximum building height, increased Floor Area Ratio (FAR), or a reduced on-site parking requirement.
EE-1.4 Develop financial incentives for new construction projects that are LEED-certified. The incentive rate should increase for each additional point earned.
EE-1.5 Preserve existing structures when feasible, and encourage adaptive reuse.
EE-1.6 Encourage commercial & industrial businesses to install cool roofs (painted white) or green roofs (with vegetation).

Goal EE-4: Promote the development of on-site renewable energy (e.g. solar, wind, biomass, and geothermal).
Actions
EE-4.1 Conduct a feasibility study to explore the possibility of installing a methane recovery system at the City’s Water Quality Control Facility (WQCF), or wastewater treatment plant, to generate electricity.
EE-4.2 Amend Municipal Code to streamline the approval of solar panels and small-scale wind turbines. Protect light access for solar energy systems.
EE-4.3 Offer a Solar Fee Waiver for any building permit application fees related to the installation of solar panels.
EE-4.4 Implement a Solar Roof Program under Property Assessed Clean Energy to minimize upfront costs for installing solar panels on residential and non-residential buildings. The landowner will pay an annual ‘special assessment’ property tax.
EE-4.5 Encourage installation and private funding of on-site renewable energy projects in Patterson, e.g. homes; roofs and parking lot solar photovoltaic arrays in the West Patterson Business Park and in commercial centers providing a large area for solar panels, and providing shade for vehicles.
EE-4.6 Collaborate with large landowners, including surrounding agricultural uses in Stanislaus County, to encourage installation and funding of on-site renewable energy projects.
EE-4.7 Encourage the Stanislaus County Environmental Resources Department to install a methane recovery system at the Fink Road Landfill to generate electricity.
Many of the goals and policies of the Sustainability Plan have been accomplished through State regulations described earlier. For example, solar panels are required by 2019 Title 24, RPS standards have resulted in large scale construction of renewable energy projects to meet the RPS renewables mandate. The CalGreen Building code requires solar ready roofs, light colored roofs for industrial buildings, and mandates recycling of construction materials among others.
Through incorporation of the measures described above, for example, the project will be designed to include energy conservation measures to meet or exceed the regulatory requirements, and would comply with the applicable policies of the Sustainability Plan. The project includes non-residential uses that would employ approximately 8,670 people, helping to improve the jobs/housing balance and to reduce the commute distances for area residents. The project will comply with the most recent energy building standards consistent with applicable plans and policies and would not result in wasteful or inefficient use of nonrenewable energy sources. Therefore, impacts would be less than significant.

3.8 - Hazards and Hazardous Materials
3.8.1 - Introduction
This section describes the existing hazards and hazardous materials setting and potential effects from project implementation on the site and its surrounding area. Descriptions and analysis in this section are based, in part, on information contained within the City of Patterson General Plan, the General Plan EIR, the California State Water Resources Control Board’s GeoTracker Database, and information provided by the property owner.
3.8.2 - Environmental Setting
Hazardous Materials
Hazardous materials, as defined by the California Code of Regulations, are substances with certain physical properties that could pose a substantial present or future hazard to human health or the environment when improperly handled, disposed, or otherwise managed. Hazardous materials are grouped into the following four categories, based on their properties:
Toxic—causes human health effects
Ignitable—has the ability to burn
Corrosive—causes severe burns or damage to materials
Reactive—causes explosions or generates toxic gases
A hazardous waste is any hazardous material that is discarded, abandoned, or slated to be recycled.
The criteria that define a material as hazardous also define a waste as hazardous. If improperly handled, hazardous materials and hazardous waste can result in public health hazards if released into the soil or groundwater or through airborne releases in vapors, fumes, or dust. Soil and groundwater having concentrations of hazardous constituents higher than specific regulatory levels must be handled and disposed of as hazardous waste when excavated or pumped from an aquifer.
The California Code of Regulations, Title 22, Sections 66261.20-24 contains technical descriptions of toxic characteristics that could cause soil or groundwater to be classified as hazardous waste.

Of the three sites, two (Patterson Beacon and CAL FIRE) are listed as ‘Case Closed’ signifying that they have been remediated to the satisfaction of the regulatory agency with jurisdiction. The third site (PRC Patterson) is listed as active.
PRC Patterson
PRC Patterson previously supported a petroleum recycling operation 1,750 feet downgradient from the Master plan areas that was abandoned in 1996. Following abandonment, a number of above ground storage tanks, underground storage tanks, and basins were removed, and soil and groundwater testing was performed. The most recent action was in 2010. Given the distance of the Master Plan from this operation and the gradient, to the extent that any soil or groundwater contamination that may be present at this site, it would not pose a risk to the Zacharias Master Plan area.
Radon
Radon is a carcinogenic, radioactive gas resulting from the natural breakdown of uranium in soil, rock, and water. Radon gas enters a building through cracks in foundations and walls. Once inside the building, radon decay products may become attached to dust particles and inhaled, or the decayed radioactive particles alone may be inhaled and cause damage to lung tissue. The United States Environmental Protection Agency (EPA) has established a safe radon exposure threshold of 4 picocuries per liter of air (pCi/l).
The California Department of Health Services has conducted more than 48,000 indoor radon tests in more than 1,700 zip codes through the State, including the one zip code that represents the City of Patterson. According to the test results from the sample taken in the City of Patterson, radon levels within the area did not exceed 4.0 pCi/l. Furthermore, Stanislaus County is identified by the United States Environmental Protection Agency as Radon Zone 3, which represents areas with low potential for radon levels exceeding 2.0 pCi/L. Therefore, radon is not considered an issue of concern in the Patterson area.
Low-Frequency Electromagnetic Fields
Electrical transmission and distribution lines emit extremely low-frequency electromagnetic fields (EMFs), which have been suspected to be linked to cancer. However, scientific research has never conclusively established a link between EMFs and cancer. In 2007, the World Health Organization issued a report titled “Extremely Low Frequency Fields, Environmental Health Criteria Monograph No. 238” that concluded that evidence between extremely low-frequency EMFs and childhood leukemia is not strong enough to be considered causal, although it did note that the issue still was of

The same report indicated that there is inadequate evidence or no evidence linking lowfrequency EMFs and health effects associated with all other diseases.
According to the California Energy Commission, no major electrical transmission lines are located within either the Baldwin or the Zacharias Master Plan Areas. The nearest high voltage electrical facility to the Zacharias Master Plan is the Turlock Irrigation District substation on Rogers Road, a distance of 0.25-mile. The nearest high voltage electrical transmission line to the Baldwin Master Plan Area is a 220 kilovolt tower line located on the west side of Interstate 5, a distance of 1.68 miles.
3.8.3 - Regulatory Framework
Federal
Federal Toxic Substances Control Act and Resource Conservation and Recovery Act The Federal Toxic Substances Control Act of 1976 and the Resource Conservation and Recovery Act of 1976 (RCRA) regulate the generation, transportation, treatment, storage, and disposal of hazardous and non-hazardous waste. The regulatory program is administered by the EPA. It mandates that hazardous wastes be tracked from the point of generation to their ultimate fate in the environment. This includes detailed tracking of hazardous materials during transport and permitting of hazardous material handling facilities. RCRA was amended in 1984 by the Hazardous and Solid Waste Act (HSWA), which affirmed and extended the “cradle to grave” system of regulating hazardous wastes. The HSWA also prohibited the use of certain techniques for the disposal of some hazardous wastes, and provided the framework for a regulatory program designed to prevent releases from USTs. The program establishes tank and leak detection standards, including spill and overflow protection devices for new tanks, and performance standards to ensure that the stored material will not corrode the tanks.
Comprehensive Environmental Response, Compensation, and Liability Act The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) introduced active federal involvement to emergency response, site remediation, and spill prevention, most notably the Superfund program. The Act was intended to be comprehensive in encompassing both the prevention of, and response to, uncontrolled hazardous substances releases.
The Act deals with environmental response, providing mechanisms for reacting to emergencies and to chronic hazardous material releases. In addition to establishing procedures to prevent and remedy problems, it establishes a system for compensating appropriate individuals and assigning appropriate liability. It is designed to plan for and respond to failure in other regulatory programs and to remedy problems resulting from action taken before the era of comprehensive regulatory protection.
Transportation of Hazardous Materials
The Hazardous Materials Transportation Act of 1974, as amended, is the basic statute regulating hazardous materials transportation in the United States. Transportation of hazardous materials is regulated by the U.S. Department of Transportation’s Office of Hazardous Materials Safety. The Office of Hazardous Materials Safety formulates, issues, and revises hazardous materials regulations

The hazardous materials regulations cover hazardous materials definitions and classifications, hazard communications, shipper and carrier operations, training and security requirements, and packaging and container specifications.
The hazardous materials transportation regulations are codified in 49 Code of Federal Regulations Parts 100-185.
The hazardous materials transportation regulations require carriers transporting hazardous materials to receive training in the handling and transportation of hazardous materials. Training requirements include pre-trip safety inspections, use of vehicle controls and equipment including emergency equipment, procedures for safe operation of the transport vehicle, training on the properties of the hazardous material being transported, and loading and unloading procedures. All drivers must possess a commercial driver’s license as required by 49 Code of Federal Regulations Part 383.
Vehicles transporting hazardous materials must be properly placarded. In addition, the carrier is responsible for the safe unloading of hazardous materials at the site, and operators must follow specific procedures during unloading to minimize the potential for an accidental release of hazardous materials.
State
Cortese List
The provisions in Government Code Section 65962.5 are commonly referred to as the “Cortese List.” The list, or a site’s presence on the list, has bearing on the local permitting process as well as on compliance with the California Environmental Quality Act (CEQA). While Government Code Section 65962.5 makes reference to the preparation of a ‘list,’ many changes have occurred related to webbased information access since 1992 and this information is now largely available on the websites of GeoTracker and EnviroStor. Those requesting a copy of the Cortese “list” are now referred directly to the appropriate information resources contained on the Internet web sites (e.g., GeoTracker and EnviroStor).
Handling and Storage of Hazardous Waste
The handling and storage of hazardous materials is regulated on the federal level by the EPA under the CERCLA as amended by the Superfund Amendments and Reauthorization Act (SARA). Under SARA Title III, a nationwide emergency planning and response program was established that imposed reporting requirements for businesses that store, handle, or produce significant quantities of hazardous or acutely toxic substances as defined under federal laws. SARA Title III required each state to implement a comprehensive system to inform federal authorities, local agencies, and the public when a significant quantity of hazardous, acutely toxic substances are stored or handled at a facility.
In California, the handling and storage of hazardous materials is regulated by Chapter 6.95 of the California Health and Safety Code. Under Sections 25500-25543.3, facilities handling hazardous materials are required to prepare a Hazardous Materials Business Plan. The business plan provides information to the local emergency response agency regarding the types and quantities of hazardous materials stored at a facility and provides detailed emergency planning and response procedures in the event of a hazardous materials release. In the event that a facility stores quantities of specific

California Hazardous Waste Control Law
The California Hazardous Waste Control Law (HWCL) is administered by the California Environmental Protection Agency to regulate hazardous wastes. While the HWCL is generally more stringent than RCRA, until the EPA approves the California program, both the state and federal laws apply in California. The HWCL lists 791 chemicals and approximately 300 common materials that may be hazardous; establishes criteria for identifying, packaging, and labeling hazardous wastes; prescribes management controls; establishes permit requirements for treatment, storage, disposal, and transportation; and identifies some wastes that cannot be disposed of in landfills.
The California Code of Regulations, Title 22, Chapter 11, Article 2, Section 66261.10 defines hazardous waste as a substance that may:
(1) Cause, or significantly contribute to, an increase in mortality or an increase in serious irreversible or incapacitating reversible, illness; or (2) pose a substantial present or potential hazard to human health or environment when improperly treated, stored, transported, or disposed or otherwise managed.
According to California Code of Regulations Title 22, substances having a characteristic of toxicity, ignitability, corrosivity, or reactivity are considered hazardous waste. Hazardous wastes are hazardous substances that no longer have a practical use, such as material that has been abandoned, discarded, spilled, or contaminated or is being stored prior to proper disposal.
Toxic substances may cause short-term or long-lasting health effects, ranging from temporary effects to permanent disability or death. For example, toxic substances can cause eye or skin irritation, disorientation, headache, nausea, allergic reactions, acute poisoning, chronic illness, or other adverse health effects if human exposure exceeds certain levels (the level depends on the substance involved). Carcinogens (substances known to cause cancer) are a special class of toxic substances.
Examples of toxic substances include most heavy metals, pesticides, and benzene (a carcinogenic component of gasoline). Ignitable substances are hazardous because of their flammable properties.
Gasoline, hexane, and natural gas are examples of ignitable substances. Corrosive substances are chemically active and can damage other materials or cause severe bums upon contact. Examples include strong acids and bases such as sulfuric (battery) acid or lye. Reactive substances may cause explosions or generate gases or fumes. Explosives, pressurized canisters, and pure sodium metal (which reacts violently with water) are examples of reactive materials.
Other types of hazardous materials include radioactive and biohazardous materials. Radioactive materials and wastes contain radioisotopes, which are atoms with unstable nuclei that emit ionizing radiation to increase their stability. Radioactive waste mixed with chemical hazardous waste is referred to as “mixed wastes.” Biohazardous materials and wastes include anything derived from living organisms. They may be contaminated with disease-causing agents, such as bacteria or viruses.

The Porter-Cologne Water Quality Act (California Water Code, Section 13000, et seq.) established the authority of the State Water Resources Control Board (State Water Board) and provided the Regional Water Quality Control Board (RWQCB) with the primary responsibility of the protection of water quality in the State of California.
Hazardous Materials Worker Safety
The California Occupational Safety and Health Administration (Cal-OSHA) and the Federal Occupational Safety and Health Administration (OSHA) are the agencies responsible for assuring worker safety by developing and enforcing workplace safety regulations in the handling and use of chemicals in the workplace. Cal-OSHA standards are generally more stringent than federal regulations. The employer is required to monitor worker exposure to listed hazardous substances and notify workers of exposure (8 CCR §§ 337-340, Chapter 3.2). The regulations specify requirements for employee training, availability of safety equipment, accident prevention programs, and hazardous substance exposure warnings.
California Fire Code
California Code of Regulations, Title 24, also known as the California Building Standards Code, contains the California Fire Code (CFC) at Part 9. The CFC includes provisions and standards for emergency planning and preparedness, fire service features, fire protection systems, hazardous materials, fire flow requirements, and fire hydrant locations and distribution.
California Department of Transportation (Caltrans) and California Highway Patrol The California Vehicle Code Section 31303 requires that hazardous materials be transported via routes with the least overall travel time, and prohibits the transportation of hazardous materials through residential neighborhoods. In California, the California Highway Patrol (CHP) is authorized to designate and enforce route restrictions for the transportation of hazardous materials. To operate in California, all hazardous waste transporters must be registered with the DTSC. Unless specifically exempted, hazardous waste transporters must comply with the California Highway Patrol Regulations, the California State Fire Marshal Regulations, and the United States Department of Transportation Regulations. In addition, hazardous waste transporters must comply with Division 20, Chapter 6.5, Article 6 and 13 of the California Health and Safety Code, and the Title 22, Division 4.5, Chapter 13 of the California Code of Regulations, both of which are administered by the DTSC.

3.8.5 - Thresholds of Significance
According to Appendix G, Environmental Checklist, of the CEQA Guidelines, hazards and hazardous materials impacts resulting from the implementation of the proposed project would be considered significant if the project would:
a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials?
b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment?
c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment?
e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working the project area? (Refer to Section 7, Effects Found Not To Be Significant)
f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?
g) Expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? (Refer to Section 7, Effects Found Not To Be Significant)
3.8.6 - Project Impacts and Mitigation Measures
This section discusses potential impacts associated with the development of the project and provides mitigation measures where appropriate.
Routine Transport, Use, or Disposal of Hazardous Materials / Risk of Upset Impact HAZ-1: Buildout of the Master Plans would not create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials and would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment.
Impact Analysis
The proposed Master Plans contemplate the development of up to 5,086 dwelling units, 7.765 million square feet of non-residential uses, two schools, parks, a trail network, and flood control basin.

Construction
The two Master Plan Areas are currently developed with agricultural land. Small quantities of potentially hazardous materials and substances would be expected to be present during construction. However, based on the duration of construction, the presence of regulatory oversight, and the overall nature of construction, the use of significant quantities of hazardous materials is not expected and would not represent a significant environmental or public hazard.
Operation
The Master Plan’s residential, mixed use, school, and park uses would not involve the use of large quantities of hazardous materials. The Zacharias Master Plan’s industrial uses would be expected to be similar to those that currently existing in the West Patterson Business Park, which are mostly distribution and logistics. These facilities receive and ship merchandise; they do not engage in manufacturing or processing; thus, they are not large quantity users of hazardous materials. To the extent that an industrial use that involves the routine use of large quantities of hazardous materials were to locate within the Zacharias Master Plan, it would be subject to state and local requirements including, but not limited to, secondary containment, regular inspection, and worker training.
Impacts would be less than significant.
Level of Significance Before Mitigation
Less than significant impact.
Mitigation Measures
None required.
Level of Significance After Mitigation
Less than significant impact.
Exposure of Schools to Hazardous Materials
Impact HAZ-2: Buildout of the Master Plans would not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within onequarter mile of an existing or proposed school.
Impact Analysis
The proposed Master Plans contemplate the development of up to 5,086 dwelling units, 7.765 million square feet of non-residential uses, two schools, parks, a trail network, and flood control basin.
Baldwin Master Plan Area
There are no existing or planned schools within the Baldwin Master Plan area or within 0.25 mile of the plan area. This condition precludes the possibility of impacts in this regard.

The proposed project includes the development of an elementary and middle school within the Zacharias Master Plan Area. Additionally, Patterson Unified School District has acquired land to develop a high school at the northwest quadrant of the Baldwin Road / Zacharias Road intersection just outside the Master Plan boundaries.
The middle school would be developed on the west side of Baldwin Road and may be within 0.25 mile of the planned industrial uses along Rogers Road or the existing Keystone Pacific Business Park to the south. Distribution centers are the closest uses within the Keystone Pacific Business Park that may be within 0.25 mile of the school. These facilities receive and ship merchandise; they do not engage in manufacturing or processing; thus, they are not large quantity users of hazardous materials. As such, the middle school would not be exposed to hazardous materials.
The elementary school would be developed on the east side of Baldwin Road and may be within 0.25 mile of the planned mixed uses. The closest types of mixed commercial uses would be restaurants, small retail, and services, which would not be large quantity users of hazardous materials. As such, the elementary school would not be exposed to hazardous materials.
The Master Plan does not propose any land uses within 0.25-mile of the high school site that would handle large quantities of hazardous materials or emit substantial hazardous air emissions.
Therefore, impacts associated with the potential exposure of schools to hazardous materials would are less than significant.
Level of Significance Before Mitigation
Less than significant impact.
Mitigation Measures
None required.
Level of Significance After Mitigation
Less than significant impact.
Government Code Section 65962.5 Sites
Impact HAZ-3: Buildout of the Master Plans would not be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would not create a significant hazard to the public or the environment.

Cortese List
Neither the Zacharias nor Baldwin Master Plan areas are listed on the Cortese List, which includes various hazardous materials databases compiled to Government Code 65962.5.
In terms of surrounding sites, PRC Patterson is listed on the Cortese List. The site is 1,750 feet from the Zacharias Master Plan area and is down gradient. As such, to the extent that any soil or groundwater contamination that may be present at this site, it would not pose a risk to either of the Master Plan areas.
Agricultural Chemicals
The majority of the Master Plan areas have been in cultivated agricultural production for decades.
Such activities typically involve application of agricultural chemicals including herbicides and pesticides. Following application, residual concentrations of these chemicals will remain in upper soil layers. Accordingly, Mitigation Measure (MM) HAZ-3a requires the applicant to conduct soil testing for agricultural chemicals and, if detected above acceptable levels, to remediate the property in accordance with best management practices.
Hazardous Building Materials
Both Master Plan areas contain structures that appear to predate the Federal bans on asbestos and lead based paint. Additionally, these structures may contain mercury and polychlorinated biphenyls.
As such, the demolition of these structures may expose human health or the environment to hazardous building materials. Accordingly, MM HAZ-3b requires the project applicant to retain a certified hazardous waste contractor to properly remove and dispose of all materials containing asbestos, lead, mercury, and polychlorinated biphenyls prior to demolition.
Electromagnetic Fields
The nearest high voltage electrical facility to the Zacharias Master Plan is the Turlock Irrigation District substation on Rogers Road, a distance of 0.25-mile. The nearest high voltage electrical transmission line to the Baldwin Master Plan Area is a 220 kilovolt tower line located on the west side of Interstate 5, a distance of 1.68 miles. Of these facilities, the Rogers Road facility is of greatest concern; the tower line is too far from the Baldwin Master Plan area to expose to low-frequency EMFs.
Power lines (and by extension substations) emit low-frequency EMFs that range from 1 to 80 milligauss directly under or next to them. This EMF range is similar to that of clothes washers, electric ranges, compact fluorescent light bulbs, and a liquid crystal display/plasma television.
Because the Rogers Road substation is 0.25-mile away from the Zacharias Master Plan area, the exposure level would be even less. Thus, impacts would be less than significant.
Level of Significance Before Mitigation
Potentially significant impact.

MM HAZ-3a Prior to issuance of grading permits for any portion of the project site where pesticides or other agricultural chemicals have been applied within the past 5 years, the project applicant shall retain a qualified consultant to perform soil testing for residual concentrations of agricultural chemicals. Soils shall be laboratory tested in accordance with California Department of Toxic Substances Control (DTSC) Guidelines. If the testing finds concentrations in excess of acceptable limits, the project applicant shall retain a qualified contractor to conduct remediation activities, which may include treatment or removal. The soil remediation activities shall be completed prior to grading.

Upon completion, the applicant shall submit documentation to the City of Patterson verifying such activities have been completed.
Level of Significance After Mitigation
Less than significant impact with mitigation incorporated.
Emergency Response and Evacuation
Impact HAZ-4: Buildout of the Master Plans would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan.
Impact Analysis
The proposed Master Plans contemplate the development of up to 5,086 dwelling units, 7.765 million square feet of non-residential uses, two schools, parks, a trail network, and flood control basin.
Baldwin Master Plan Area
The Baldwin Master Plan contemplates a looped internal circulation network that would connect to existing segments of the City of Paterson’s roadway network at Baldwin Road and the City of Patterson Corporation Yard access road. Thus, two points of connection would be provided.
Moreover, the Master Plan incorporates the General Plan Circulation Element’s roadway sections and, thus, the internal roadways would meet City standards for access and circulation. As such, adequate emergency response and evacuation would be provided.
Zacharias Master Plan Area
The Zacharias Master Plan contemplates an internal circulation network with multiple connections to the City of Paterson’s roadway network at Rogers Road, Zacharias Road, Baldwin Road, and Ward Avenue. The Zacharias Master Plan also contemplates an East-West Connector that would link the Master Plan area to State Route 33. Additionally, two Emergency Vehicle Access (EVA) points would be provided at the existing Ivy Avenue and Rose Avenue cul-de-sacs. Moreover, the Master Plan

3.9 - Hydrology and Water Quality
3.9.1 - Introduction
This section describes the existing hydrology and water quality setting, and potential effects from the Zacharias and Baldwin Master Plan Projects (project) implementation on the project site and its surrounding area. Individual planning areas are highlighted where needed, otherwise the discussions in this chapter pertain to both the Zacharias and Baldwin planning areas. Balance Hydrologics assessed the potential for flooding in the Zacharias Master Plan area. An accompanying Technical Memo is provided in Appendix H. Additional information was provided by the City of Patterson, Federal Emergency Management Agency, the Central Valley Regional Water Quality Control Board, California Department of Water Resources, and National Oceanic and Atmospheric Administration.
3.9.2 - Environmental Setting
Regional climate can be characterized as a semi-arid Mediterranean climate, with cooler winters and hotter summers typical of the transition zone from the coastal mountains to the San Joaquin Valley.
Monthly temperatures in the winter range from lows of mid-30° F to highs of low-60° F, and in the summer range from lows of mid-50° F to highs of mid-90° F. The project site receives approximately
11.5 inches of rain per year (Table 3.9-1). Modest rainfall totals can be attributed to the general climate as well as to a rain shadow effect of the California Coast Diablo Range to the west.
Average monthly precipitation, temperature, and reference evapotranspiration (ETo) for the period are shown in Table 3.9-1. Precipitation exceeds ETo only in the winter month of January and the two are approximately in equilibrium in December and February. ETo exceeds precipitation on a yearly basis at a 5:1 ratio, with the largest deficits in summer months with high temperatures and incidental amounts of rain.

Master Plan Area
The Baldwin and Zacharias and Baldwin Master Plan areas are predominately used for agricultural production and contain no stormwater drainage infrastructure. Rural residential land is located in the eastern portion of the Zacharias planning area. No formal storm drainage facilities are located

Under existing conditions, runoff either ponds on-site and infiltrates into the local aquifer or flows into ditches or swales that convey to city streets that drain to Salado Creek. The Zacharias project area slopes gently away from Del Puerto Creek and is over one-half mile from the creek, thus runoff flows away from the creek rather than toward it. Storm drainage facilities are expected to be built out as development of these areas moves forward per the City of Patterson Draft Water Master Plan (WMP).
Surface Hydrology
The Patterson area features a network of natural streams and rivers, whereas predominately manmade surface water elements include canals and ditches that are used for water supplies and agricultural irrigation. The following is a description of the principal surface water bodies local to the Patterson area.
San Joaquin River
Patterson is located within the San Joaquin River watershed. The San Joaquin River is the secondlongest river in California, extending 300 miles from the Sierra Nevada Mountains to the San Joaquin Delta. The river and its tributaries drain a watershed encompassing approximately 32,000 square miles. In the Patterson area, the river is located approximately 2 miles east of the City and drains from south to north.
Del Puerto Creek
Del Puerto Creek is the principal natural waterway on the north side of the City of Patterson with a contributing watershed area of 72.6 square miles. The waterway is an intermittent stream with natural flows during the rainy season. Water flowing through the creek channel in the dry season comes from irrigation runoff (agricultural) or potentially seepage from irrigation ditches and/or aqueducts. The creek originates in Del Puerto Canyon in the Diablo Range west of Patterson, enters the area from the west through culverts under Interstate 5, the California Aqueduct, and the DeltaMendota Canal, and then meanders northeastward before discharging into the San Joaquin River approximately 4.75 miles north of the City limits. Although there is no official watershed delineation of Del Puerto Creek on the alluvial plain east of Interstate 5 other than along the channel itself (Exhibit 3.9-1), Federal Emergency Management Agency (FEMA) flood mapping indicates that overbank flood flows have the potential to move water into and through the project area (see “Flood Hazard Mapping” section for further information). The Zacharias planning area overlaps with the FEMA flood zone described above as the alluvial plain slopes southeastward, away from Del Puerto Creek. The City of Patterson General Plan indicates that Del Puerto Creek and its associated overbank alluvial plain are subject to flooding during major storm events.
Salado Creek
Salado Creek is the principal natural waterway that runs through the urbanized portions of the City of Patterson with a contribution watershed area of 25.3 square miles. The creek is an intermittent stream originating in the Diablo Range west of Patterson with natural flows during the rainy season.
Water flowing through the creek channel in the dry season comes from irrigation runoff (agricultural or urban) or potentially seepage from irrigation ditches and/or aqueducts. The creek is channelized before it enters Patterson from the south, remains channelized through the City, and ultimately

Urban discharge primarily originating from irrigation of lawns and parks can be found in the channel running through the City throughout the year. In the late 1990s, flood control improvements were made to Salado Creek, including enlarging the channel within the city limits and installing a 96-inch-diameter pipeline under Olive Avenue that runs from the railroad tracks at State Route 33 to the San Joaquin River. The Baldwin planning area is within the Salado Creek watershed, located about 2,000 feet west of the creek channel as it approaches the City boundary. The channelized creek within the City is piped along the boundary of the Zacharias planning area from east of Cliff Shallow Drive to Ward Avenue.
Delta Mendota Canal
The Delta-Mendota Canal is a 117-mile-long channel that is part of the Central Valley Water Project, a joint federal and state water project that spans the length of the San Joaquin Valley and provides water for agricultural, urban, and wildlife use. The canal conveys water from the Tracy Pumping Plant near Tracy to the Mendota Pool in Fresno County. In the Patterson area, the canal meanders through the west side of the City, approximately parallel to the east side of Interstate 5. No portion of this project is intersected by the Delta-Mendota Canal.
California Aqueduct
The California Aqueduct is a 444-mile-long conveyance channel that is part of the State Water Project, a state-built and -operated water storage and delivery system that provides water to 29 urban and agricultural water suppliers throughout California. The aqueduct conveys water from the Banks Pumping Plant near Tracy to a point south of the Tehachapi Mountains. In the Patterson area, the aqueduct runs between the east side of Interstate 5 and the Delta-Mendota Canal. No portion of this project is intersected by the California Aqueduct.
Irrigation Ditches
Irrigation ditches have been built throughout the alluvial plain east of the Diablo Range foothills. This area is prime agricultural land that depends on the regular delivery of water to fields, including existing agricultural fields in the project area. The ditches run parallel to the San Joaquin River and the gentle slope of the alluvial plain and generally perpendicular to the creeks. The Patterson Irrigation District was formed in 1955 to manage water delivery to agricultural lands (Paterson Irrigation District Water Management Plan 2016) in the Patterson area. Water allocations in 2010, the most recent year with data, came from Federal agricultural water via the Delta-Mendota Canal (approximately 6%), from local San Joaquin River surface water (approximately 82 percent), and from District groundwater (approximately 12 percent).
Surface Water Quality
Del Puerto Creek, Salsado Creek, and the San Joaquin River are listed on the U.S. Environmental Protection Agency (EPA) 303(d) list of impaired water bodies and associated pollutants, as administered by the Central Valley Regional Water Quality Control Board (RWQCB). Listings in the current 303(d) (Central Valley RWQCB 2016) are defined as those water bodies that do not meet, or are not expected to meet, water quality standards for a specified pollutant. For water bodies identified as impaired, the State is required to develop a Total Maximum Daily Load (TMDL) to account for all sources of pollutants from both point and nonpoint sources that are attributed to its

The FEMA Flood Insurance Rate Map (FIRM) associated with the Flood Insurance Study (FIS 06099CV000A) that contains the Zacharias planning area indicates that some portions of the project lie within Del Puerto Creek Zone AO (Exhibit 3.9-2), which is a flood hazard area predicted to have flood depths of 1 to 3 feet (generally sheet flow on sloping terrain) in a 100-year flood event (1 percent annual chance flood hazard)
The FEMA FIRM that contains the Baldwin planning area (also FIS 06099CV000A) indicates that a minor portion of the eastern edge of the project lies along the western edge of Salado Creek shaded Zone X area (Exhibit 3.9-3), which is a flood hazard area predicted to have flood depth of less than 1 foot in a 500-year flood event (0.2 percent annual chance flood hazard).
Groundwater
The City of Patterson overlies the Delta-Mendota Groundwater Subbasin (5-022.07; Delta-Mendota Subbasin), which covers 1,170 square miles in western Fresno, Madera, Merced, and Stanislaus counties and is a subbasin of the San Joaquin Valley Groundwater Basin. A summary of hydrogeologic characteristics of the Delta-Mendota Subbasin as reported in California Department of Water Resources (DWR) Bulletin 118 is detailed as follows.
Hydrogeologic Formations
The primary groundwater-bearing units of the Delta-Mendota Subbasin consist of unconsolidated terrace, alluvium, and flood-basin deposits of alternating beds of clay, sand, and gravel in the Tulare Formation geologic unit, which includes the alluvial fan materials of Del Puerto Creek and Salado Creek. The relatively large grain size of the upslope alluvial fan deposits suggests their value as possible recharge sites, whereas the downslope Corcoran Clay layers define the confining units important to the Delta-Mendota Subbasin aquifers.
The Delta-Mendota Subbasin near Patterson contains two primary aquifers separated by the Corcoran Clay confining unit: a lower fully-confined water-bearing zone (“lower aquifer”) and an upper semi-confined zone (“upper aquifer”). The Corcoran Clay unit is present under the City of Patterson and thins out to the west as the Del Puerto Creek alluvial fan rises toward the base of the Coast Range near Interstate 5 and the Delta-Mendota Canal. The lower aquifer can range below ground surface to about two-thousand feet deep. The upper aquifer extends to depths ranging from about 150 feet to greater than 350 feet below ground surface. The lower aquifer is utilized as a source of groundwater for drinking water and other uses such as agricultural irrigation, whereas upper aquifer groundwater is of lower quality. While the upper aquifer water is considered nonpotable, it is used for agricultural irrigation.
Local Hydrogeological Studies
Kenneth D. Schmidt and Associates (KSA) conducted a series of hydrogeological studies in the Patterson area over the past 20 years. In the most recent studies, KSA drilled new borings and performed well tests along the Del Puerto Creek alluvial fan in 2017 to assess the best site conditions for potential recharge basins that could recharge the lower aquifer recharge. This study confirmed

Groundwater Level Trends
Within the area of the Delta-Mendota North-Central Groundwater Sustainability Plan (GSP), the long-term trends for both the upper and lower aquifers indicate similar levels of fluctuations over time; groundwater elevations typically increased or remained relatively stable during the period from the 1980s through the early 2000s. Wells in the lower aquifer generally exhibited fewer seasonal differences in groundwater elevations, with a general decline during the 2012-2016 drought years followed by recovery in 2017-2018.
Based on wells monitored, maintained and measured by DWR and cooperators, groundwater elevations in upper aquifer wells were generally stable (±10 feet) between 2005 and 2010. The Groundwater Information Center’s interactive map showed that depth-to-groundwater remained steady in the upper aquifer from 2012 to 2018, in the range of 80- to 100-feet below ground surface in the proposed Zacharias project area.
A pattern of increased drought-driven groundwater pumping, accompanied by declining groundwater elevations, followed by recovery is a predominant factor to be considered in the sustainable management of both aquifers in the Delta-Mendota Subbasin.
Groundwater Recharge
Most of the natural recharge to the lower aquifer of the Delta-Mendota Subbasin near Patterson occurs from runoff and infiltration in the alluvial fans from the Coast Range streams along the western side of the basin. Rainfall, creek and overland runoff and irrigation water percolation recharge the upper aquifer.
Natural inflows to the upper and lower aquifers in the Patterson area were estimated by KSA and reported in the City’s Water Master Plan to be 3,500 acre-feet per year (AFY) in the upper aquifer and 8,900 AFY in the lower aquifer, based on basin hydraulic conductivity, transmissivity, and gradients. Additional seepage from irrigation canals, percolation of irrigation water, and stream flow percolation likely contribute additional recharge into the upper aquifer.
The WMP identifies the area between the Delta-Mendota Canal and the California Aqueduct as potentially most amenable to development of percolation ponds as a means to recharge the lower aquifer, with the intent of implementing a pilot recharge project to determine specific recharge capacity. Specifically, subsurface geologic conditions, investigated via well boring logs beneath the Del Puerto Creek alluvial fan near the Delta-Mendota Canal suggest favorable conditions for intentional lower aquifer recharge, whereas to the east along Zacharias Road conditions are not as favorable.
Groundwater Storage
Annual changes in groundwater storage for both the upper and lower aquifers in the Northern and Central Delta-Mendota Region were generated through the development of recent water year (WY) budgets to estimate annual and cumulative change in storage relative to the start of the historic

Cumulative change in storage from WY2003 through WY2013 were derived from available hydrograph data, whereas cumulative change in storage from WY2014 through WY2018 were estimated based on the average change in storage by water year type (wet, average, dry, and Shasta critical) as correlated between WY2003 to WY2013. Both aquifers followed the same trend: changes in storage were negative for the same 12 out of the 16 years of study, and negative for same four out of the eight wet and average water year types. Despite periods of wet conditions where recharge outpaced extractions, an overall declining trend in groundwater storage was observed in both the upper and lower aquifers. Between WY2003 and WY2018, groundwater storage declined more rapidly in the upper aquifer at 830,000 acre-feet (AF) compared to the lower aquifer at 160,000 AF.
Groundwater Quality
Groundwater in the Delta-Mendota Subbasin is characterized by mixed sulfate to bicarbonate types in the northern and central portion with areas of sodium-chloride- and sodium sulfate-rich waters in the central and southern portion. Shallow, saline groundwater occurs within about 10 feet of the ground surface over a large portion of the Delta-Mendota Subbasin with localized areas of high concentrations of iron, fluoride, nitrate, and boron; the primary constituents of concern are nitrates, total dissolved solids (TDS) and pesticides.
Groundwater in shallower aquifers, such as that above the Corcoran Clay within the City of Patterson, generally contain higher concentrations of anthropogenic contaminants than in deeper aquifers, indicating pollutants from current land use activities. Reported chemical contaminants that may affect groundwater in the San Joaquin Valley Region include salinity (evaporation and poor drainage); boron and chloride (evaporation); nitrate (fertilizer); agricultural pesticides and herbicides; volatile organic compounds (industrial solvents, petrochemicals); and naturally occurring arsenic, gross alpha, and uranium. In the City of Patterson, two production wells supply water from the upper aquifer. These withdrawals can exceed total dissolved solids (salinity) maximum contaminant level (MCL) as well as nitrate and chloride MCL standards and thus are used exclusively for outdoor irrigation and other non-potable uses.
City of Patterson Municipal Water Supply
The City supplies citizens and businesses with potable water from seven production wells screened in the lower aquifer, which requires only disinfection prior to distribution. Water quality in the lower aquifer is generally suitable for potable use, however there are some instances of high TDS and Chrome 6 levels. Hexavalent chromium (chromium 6) was detected above the MCL of 10 micrograms per liter in the City supply when testing for a stricter standard was ordered in 2014 by the State Water Resources Control Board, Division of Drinking Water. The City proposed a Corrective Action Plan in 2015 that included moving well screen depths to portions of the aquifer that potentially contain lower chromium 6 levels. However, in 2017, the chromium 6 MCL was withdrawn as stipulated by a court order so changes to screen depths were not implemented. A new standard has not yet been established; however, the Chrome 6 levels would not be in compliance if the 2014 standard was re-imposed. The City’s most recent Consumer Confidence Report indicates that there were no sampled constituent exceedances of State or Federal MCL standards in the lower aquifer.

Total potable water demand in 2018 was 3,102 AFY. Due to implementation of an effective water conservation program, 2018 water demand was about 16 percent lower than 2013 water demand as reported in the WMP. Future potable water demand for the year 2040 was estimated to be 9,642 AFY, taking into account the proposed project and the City’s planned conservation efforts at the time the WMP and UWMP (2016) were developed. The City’s UWMP reports a baseline (current) water use rate of 135 gallons per capita per day (GPCD) versus the 2020 target water use rate of 164 GPCD. More recent data were not available, though the UWMP reported that the City expected to be in compliance in 2020 based on current usage and conservation patterns.
3.9.3 - Regulatory Framework
Federal
Clean Water Act
Section 303 of the Clean Water Act requires states to adopt water quality standards for all surface waters of the United States. Water quality standards may be numeric, although narrative criteria based upon biomonitoring methods may be employed where numerical standards cannot be established or where they are needed to supplement numerical standards. See a description of the California State Porter-Cologne Water Quality Control Act, below, for California’s implementation framework. Standards are based on the designated beneficial use(s) of the water body. Where multiple uses exist, water quality standards must protect the most sensitive use.
National Pollutant Discharge Elimination System
Construction
Section 402 of the Clean Water Act mandates that certain types of construction activity comply with the requirements of the National Pollutant Discharge Elimination System (NPDES) stormwater program. In California, permitting occurs under the statewide General Permit for Stormwater Discharges Associated with Construction Activity (“Construction Permit”), issued through the State Water Resources Control Board (State Water Board) and implemented and enforced by nine Regional Water Quality Control Boards (RWQCBs). The project site is within the boundaries of the Central Valley RWQCB.
The NPDES General Permit for Storm Water Discharges Associated with Construction Activity (Order 2009-0009-DWQ as amended by Order 2010-0014-DWQ and Order 2012-0006-DWQ) – Order 2012- 0006-DWQ became effective on July 12, 2012 and covers construction projects that disturb one (1) or more acres or are part of a larger common plan of development that disturbs more than 1 acre in total (e.g., large linear utility projects). The Order requires that construction activities that disturb land equal to or greater than 1 acre be permitted under the NPDES program, and that a Waste Discharge Identification Number must be on file with the City, before any work begins. A project must also submit a Notice of Intent to the State Water Board prior to the beginning of construction.
Once the Construction Permit is issued, it requires permittees to develop and implement a Storm Water Pollution Prevention Plan (SWPPP) that shall be amended or revised when necessary to meet the following objectives:

1. Identify all pollutant sources of sediment that may affect the quality of storm water discharges associated with construction activity (stormwater discharges) from the construction site.
2. Identify non-storm water discharges.
3. Identify, construct, and implement Best Management Practices (BMPs) in accordance with a time schedule to reduce or eliminate pollutants in storm water discharges and authorized non-storm water discharges from the construction site during construction.
4. Develop a maintenance schedule for BMPs installed during construction designed to reduce or eliminate pollutants after construction is completed (post-construction BMPs).
Over the last decade, the State Water Board adopted a series of amendments to the Construction Permit. One of the most notable amendments involves Best Management Practices (BMPs). The Construction Permit now requires specific BMPs as well as numeric action levels (NALs) so that minimum federal standards are met, a SWPPP and a Rain Event Action Plan (REAP) are developed by a certified Qualified SWPPP Developer (QSD), and that the discharger comply with specific BMPs and NALs. Construction activities are also required to control pollutant discharges that utilize best available technology economically achievable (BAT) for toxic and non-conventional pollutants, and best conventional pollutant control technology (BCT) for conventional pollutants.
Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, excavation, or landscaping operations. Regulations and requirements must be met during the construction phase of all new development projects, primarily through control of discharges of pollutants into storm drains or creek channels. Avoidance of such discharges can be attained by the use of seasonal- and phase-appropriate effective BMPs, including erosion control, run-on and runoff control, sediment control, active treatment systems, good site management, and non-storm water management through all phases of construction until the site is fully stabilized by landscaping or the installation of permanent erosion control measures. These criteria are required to be established in the SWPPP, conforming to the prevailing CASQA BMP construction handbook, Caltrans stormwater quality construction site BMP handbook, and/or any other or newer BMPs available since the release of the handbooks, as required given project needs. When project construction is completed, the applicant must file a notice of termination.
Stormwater Discharges
The current municipal stormwater permit under the NPDES permit program (Phase II Small MS4 General Permit, 2013-0001-DWQ; “Phase II Permit”) that is in effect for the City of Patterson was issued by the State Water Board in 2013. The permit requires that permittees implement controls to reduce discharge of pollutants from their MS4s to the maximum extent practicable and to effectively prohibit non-stormwater discharges into municipal storm drain systems and watercourses. The permit incorporates stormwater pollution management requirements for post construction stormwater management as set forth in Section E.12.
Section E.12 requires that new development projects incorporate post-construction stormwater pollution management measures in addition to standard BMPs that include stormwater treatment

The Porter-Cologne Water Quality Control Act of 1969 authorized the State Water Board to provide comprehensive protection for California’s waters through water allocation and water quality protection. The State Water Board implements the requirements of the Clean Water Act Section 303, indicating that water quality standards have to be set for certain waters by adopting water quality control plans under the Porter-Cologne Act. The Porter-Cologne Act established the responsibilities and authorities of the nine RWQCBs, which include preparing water quality plans for areas in each region, identifying water quality objectives, and issuing NPDES permits and Waste Discharge Requirements.
Central Valley Regional Water Quality Control Board
The current Central Valley RWQCB Basin Plan (2018) includes the Delta-Mendota Canal Hydrologic Unit 541.10 Patterson, a sub-basin of the San Joaquin River Hydrologic Unit. Beneficial uses designated for the Patterson sub-unit include municipal and domestic supply, irrigation, stock watering, recreation-1 (contact), recreation-2 (other noncontact), freshwater habitat (warm), and wildlife habitat. The Basin Plan designates or establishes such beneficial uses of waters to be protected, water quality objectives to protect those uses, and a program of implementation needed for achieving the objectives. Water quality objectives are defined as limits or levels of water quality constituents and characteristics established for reasonable protection of beneficial uses or prevention of nuisance.

The UWMPs must be updated every five years to include projections of both potable and recycles water use, identify current reclamation practices, address additional alternative conservation measures, and describe findings, actions, and planning related to a number of water conservation and reclamation measures. In addition, an Urban Water Shortage Contingency Plan must be prepared and updated every five years, specifying proposed measure for response to shortand long-term water shortages.
The State of California passed Senate Bill (SB) X7-7 as a water conservation measure seeking a 20 percent statewide reduction in urban per capita water use by December 31, 2020. SB X7-7 required that each retail water agency preparing a 2010 UWMP must calculate baseline water use as well as an interim (for 2015) and final (for 2020) water use reduction target using specified guidelines.
Sustainable Groundwater Management Act
The State of California established a legislative framework for sustainable groundwater management, the Sustainable Groundwater Management Act (SGMA), that became law on September 16, 2014. SGMA requires governments and water agencies to halt overdraft and bring groundwater basins into balanced levels of pumping and recharge within a specified timeframe depending on a groundwater basin prioritization system that ranks each groundwater basin’s overdraft condition (e.g., low, medium, high priority, etc.).
Groundwater basins in California are vulnerable to six types of undesirable results (UCS 2017), which GSPs are to be designed to avoid. These undesirable results include:
1. Significant and unreasonable reduction of groundwater storage.
2. Significant and unreasonable lowering of groundwater levels.
3. Significant and unreasonable seawater intrusion.
4. Significant and unreasonable degraded water quality.
5. Significant and unreasonable land subsidence.
6. Significant and unreasonable depletions of interconnected surface water.
There is no technical definition for sustainability. It is not simply the presence or absence of a result like land subsidence that is in itself undesirable; rather, it is the extent to which the result is undesirable. For each undesirable result, the local community will be tasked to decide how much damage is acceptable, or conversely, how much repair is desired. Despite the flexibility around local sustainability goals, there are two definite boundaries that limit the interpretation of sustainability.
The California Water Code states that one basin’s definition of sustainability cannot threaten others’ ability to achieve their sustainability goals (Section 10733(c)), and, second, indicates that both continued overdraft and significant depletion of interconnected surface waters are unacceptable long-term strategies (Section 10735.2(a)(5)).

SGMA requires that local agencies form Groundwater Sustainability Agencies (GSAs) to manage basins sustainably and that GSPs are adopted for these critically overdrafted basins by January 2020 with measures necessary to attain sustainable conditions in those subbasins by 2040. A GSP must generally outline how the GSA will implement, manage and measure specific actions for the health and viability of the basin. The City of Patterson has elected to form its own GSA within City boundaries and is a partner in the Northern & Central Delta-Mendota GSP Group along with other local GSAs.
A public draft version of the Northern & Central Delta-Mendota groundwater sustainability plan (GSP, 2019) was submitted to the State of California in January 2020 for review and public comment.
Groundwater management measures expected to be implemented include:
Increased conservation and efficiency
Increased groundwater recharge
Increased water recycling and reuse
Integrated groundwater management with other water resources (such as stormwater) Lower aquifer pumping limitations to minimize inelastic land subsidence The GSP (2019) includes policies from the City of Patterson’s General Plan for urban development and land use projections to 2030 and 2050, including designated expansion areas that encompass future developments the Zacharias and Baldwin planning areas. These planning areas are included in Chapter 5.4.6 in the GSP under the “Projected Water Budget with Climate Change and Project & Management Actions” section, where future projected conditions are evaluated.

Title 17, Chapter 17.12 sets forth standards for development in flood hazard areas. The chapter requires that new construction comply with federal floodplain safety requirements, including elevating residential structures 1 foot above the 100-year flood elevation in FEMA Zones A1-30, AE, and AH. Residential structures in Zone AO must be elevated, including basement, above the highest adjacent grade as least as high as the depth number specified in feet on the FIRM plus one foot, or at least three feet if no depth number is specified. Nonresidential structures either adhere to residential requirements or be floodproofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water, is resistant to hydrostatic and hydrodynamic loads and effects of buoyancy and is certified by a registered professional engineer or architect.
3.9.4 - Methodology
Balance Hydrologics, Inc. analyzed the potential hydrologic and water quality impacts associated with the proposed Zacharias Master Plan, based on the Administrative Draft Environmental Impact Report Project Description and other project documents within the context of local, state, and federal regulations.
Phased development is expected within the project envelope, which is defined as two distinct areas.
The Zacharias planning areas is located north of existing Patterson city limits. Areas to the west of Baldwin Road are designated as industrial and commercial space, while residential neighborhoods are planned for areas east of Baldwin Road. The Baldwin planning area is located south of existing Patterson city limits at the current southern terminus of Baldwin Road. Residential neighborhoods are planned for this area. From a hydrologic and water quality perspective, potential impacts of the planning areas would generally be similar and thus are grouped together for analysis; when needed the Zacharias or Baldwin planning areas are individual analyzed.
3.9.5 - Thresholds of Significance
In accordance with Appendix G of the CEQA Guidelines, the impact of the proposed project on hydrology and water quality would be considered significant if it would:
a) violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality;
b) substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin;

(iii) create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems, or provide substantial additional sources of polluted runoff; or
d) in flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation; (Refer to Section 7, Effects Found Not To Be Significant) e) conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan.
3.9.6 - Project Impacts and Mitigation Measures
This section discusses potential impacts associated with development of the project and provides mitigation measures where appropriate.
Water Quality
Impact HYD-1: Buildout of the Master Plan may violate water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality?
Impact Analysis
This impact will address surface water quality and groundwater quality.
Surface-Water Quality
Construction Phase
Project implementation would involve the development of up to 5,391 dwelling units, 7,765,000 square feet of non-residential uses, 29 acres of school space, 65 acres of park space, and 13 acres of open space on 1,293 acres at full build-out across the combined Zacharias and Baldwin planning areas (WSA 2020). Existing PID irrigation canals that cross the project may be realigned to accommodate roadway improvements and may be relocated underground as pipelines. A setback will be established between the Delta-Mendota Canal and development of the Baldwin planning area. For the purposes of this EIR, buildout is assumed to occur over a 20-year period.
During construction activities in the Zacharias planning area, clearing, grading and other activities would increase the potential for on-site erosion, potentially leading to increased turbidity and sedimentation via overland sheet flow into existing PID irrigation canals as well as Salado Creek and ultimately into the San Joaquin River. The southern-most boundary east of Baldwin Road in the Zacharias planning area is adjacent to a piped section of Salado Creek from east of Cliff Shallow Drive to Ward Avenue. The creek is daylighted upstream and downstream of this area, and there is

During construction activities in the Baldwin planning area, clearing, grading and other activities would increase the potential for on-site erosion, potentially leading to increased turbidity and sedimentation via overland sheet flow into Salado Creek and ultimately into the San Joaquin River. In addition, the western boundary of the Baldwin planning area is adjacent to the Delta-Mendota Canal, so there is potential for soil erosion to occur along project boundaries during construction in areas where temporary soil storage is required.
Other pollutants that might impact surface water quality during project construction include petroleum products (gasoline, diesel, kerosene, oil and grease), hydrocarbons from asphalt paving, paints, solvents, and litter. An accidental release of any of these substances could degrade the water quality of the surface water runoff.
Because the project would disturb more than one acre of land, the applicant is required to prepare a Stormwater Pollution Prevention Plan (SWPPP), per the NPDES Construction Permit requirements through the State Water Resources Control Board (State Water Board). The SWPPP would address potential erosion and sedimentation issues through a project-specific erosion control plan, as well as other best management practices (BMPs) to reduce the potential for spills and other contamination from on-site construction activities. Appropriate BMP implementation measures for control of sediment and other pollutants from construction sites can be found in the most recent version of the CASQA BMP construction handbook, Caltrans stormwater quality construction site BMP handbook, and/or any other or newer BMPs available since the release of the handbooks, as required given project needs. The project SWPPP is likely to include, but is not limited to, the following BMPs related to construction water-quality impacts:
If the entire site is not graded in a single operation, leave existing vegetated areas undisturbed until construction of improvements on each portion of the development site is ready to begin; Immediately re-vegetate or use erosion control measures to otherwise protect all disturbed areas from both wind and water erosion during and after completion of grading; Collect storm water runoff into stable drainage channels and/or small drainage basins to prevent the buildup of large, potentially erosive storm water flows; Direct runoff away from all areas disturbed by construction; Use sediment ponds or siltation basins to trap eroded soils before runoff is discharged into onsite or off-site drainage culverts and channels; Install straw rolls, hay bales or other approved materials below all disturbed areas adjacent to Salado Creek to prevent eroded soils from entering the stream channel. Maintain these facilities until all disturbed upslope areas are fully stabilized, in the opinion of the City Engineer;
To the extent possible, schedule major site development work involving excavation and earthmoving for construction during the dry season;

Avoid cleaning, fueling, or maintaining vehicles on-site, except in an area designated to contain and treat runoff; and
During and after construction, inspect all drainage facilities immediately downstream of the grading site for accumulated sediment, and clear these facilities of debris and sediment as necessary;
BMP performance and effectiveness shall be determined either by visual means where applicable (e.g., observation of above-normal sediment release), or by actual water sampling in cases where verification of contaminant reduction or elimination (such as inadvertent petroleum release) is required by the Central Valley RWQCB to determine adequacy of the measure;
In the event of significant construction or final landscape installation delays, native grasses or other appropriate vegetative cover shall be established on the construction site as soon as possible after disturbance, as an interim erosion control measure throughout the wet season.
In compliance with the requirements of the statewide NPDES Construction Permit, the City or its qualified SWPPP developer will prepare a SWPPP for submittal with a Notice of Intent to the Central Valley RWQCB prior to the start of construction. The SWPPP would specify BMPs to be employed during the construction phase to control sediment loads and pollutants. The SWPPP shall include the minimum BMPs required for the identified Risk Level of the project and receiving waters. BMP implementation shall be consistent with the BMP requirements in the most recent version of the California Stormwater Quality Association Stormwater Best Management Handbook-Construction or the Caltrans Stormwater Quality Handbook Construction Site BMPs Manual.
Mitigation Measure HYD-1a requires implementation of a SWPPP in conjunction with each development phase of the Master Plans. Proper implementation of the project-specific SWPPP would reduce the potential construction-related water quality impacts to a less than significant level.
Operational Phase
The proposed project would increase impervious surfaces as new roads, parking areas, and rooftops are built out. Parking lots are prone to contributing oil, grease, metal brake dust, and trash to stormwater runoff. While rooftop runoff does not typically contribute stormwater contaminants at levels as high as from parking areas, contributions from rooftops includes airborne deposition of particulate matter that may subsequently be carried into the stormwater drainage system and could be elevated given the proximity of Interstate 5 and traffic associated with the project itself.
Impervious areas and associated stormwater drainage systems can provide an efficient conveyance system for other potential contaminants, including fertilizers and pesticides, to the receiving streams. Untreated, the above contaminant sources are likely to adversely impact water quality in Salado Creek and downstream San Joaquin River.

The Phase II Permit requires project proponents to incorporate site design measures, source controls, stormwater treatment measures, and/or other low impact development (LID) measures to reduce stormwater runoff and limit the transport of pollutants to receiving waters. The Phase II Permit also requires implementation of source control measures for specific pollution-generating activities such as accidental spills or leaks and landscape/outdoor pesticide use. Potential sources of runoff pollutants are identified by the City (such as Patterson General Plan Policy PS-3.13: Surface pollutant control and Policy PS-3.14: Erosion Control, as well as Patterson Municipal Code Chapter 13.32) that require implementation of appropriate permanent and operational source control BMPs.
Under existing conditions, stormwater runoff within the existing Zacharias planning area predominantly infiltrates into agricultural fields or moves across the landscape as overland flow toward Salado Creek to the south-southeast. Stormwater runoff within the existing Baldwin planning area predominantly infiltrates into agricultural fields or moves across the landscape to the east as overland flow toward Salado Creek. Under post-project conditions, stormwater discharge from impervious surfaces, including roof, roadway, sidewalk and hardscape would be directed to on-site stormwater runoff basins that meet Phase II Permit water quality treatment requirements. The master plans have designated basin locations that would be worked into the landscaped areas surrounding the proposed buildings, parking areas, roads, and related impervious infrastructure.
Stormwater runoff basins would be located in areas where design percolation rates have been tested and calculated by a registered hydrogeologist (Soares, 2013; Ballard and Krause, 2019a,b,c and 2020), and which support fulfillment of Phase II Permit BMP design requirements. Under postproject conditions, the project would include approximately 765 acres of permeable surfaces (approximately 62 percent of the 1227.1-acre project site), suggesting that ample space would be available in which to accommodate appropriate stormwater treatment BMP features.
The proposed project is required to comply with provisions of the Phase II Permit for postconstruction best management practices and incorporate LID concepts into the project design in order to reduce post-project runoff (and associated non-point-source contaminant transport) to receiving waters. The project applicant will be required to prepare and submit a Stormwater Quality Management Plan (SWQMP) to the City of Patterson for review and approval prior to issuance of building permits for the proposed project. The plan would require documentation of stormwater quality control measures to ensure that runoff associated with operational activities would not contribute to the degradation of water quality in downstream waterways. Proper design, sizing, and implementation of the stormwater basins would effectively address both water quality and hydromodification concerns. Documentation is required once final designs are completed in order to verify compliance with the water quality and hydromodification provisions. Implementation of the stormwater control plan, in compliance with the NPDES Phase II permit, would reduce potential stormwater quality and hydromodification impacts to a less than significant level. No further mitigation is required.

The stormwater treatment BMPs discussed above are intended to maximize infiltration, assuming infiltration rates are sufficient and that depth to the seasonal groundwater peak elevation meets the performance/design standards of the BMPs. If not, underdrains may be required. Under either scenario, the BMPs are expected to meet water quality treatment standards as required under Provision E.12 of the Phase II Permit.
All stormwater runoff within the Zacharias planning area will ultimately drain to two lakes, and then be pumped up to a basin for recharge to groundwater in order to support the City’s effort to sustainably manage the lower aquifer that supplies potable water to the City. Technically, stormwater treatment BMPs may not be required in this area, as the planning area will not discharge to the City storm drain system or to any surface receiving water (such as Del Puerto Creek, Salado Creek or the San Joaquin River; essentially, the planning area will operate as a large self-retaining area). However, direct drainage of stormwater to the receiving detention/retention ponds without treatment could result in accumulation of contaminants within the retention lake, that could ultimately be pumped up to the recharge basin.
Pretreatment, which refers to design features that provide settling of large particles before stormwater runoff enters a stormwater treatment control measure, is important to ensure proper operation of a bioretention facility and reduce the long-term maintenance burden. Pretreatment (e.g., vegetated swales, proprietary devices) must be provided to reduce the sediment load entering a bioretention facility in order to prevent the engineered planting media and/or underlying soil from being occluded prematurely and maintain the infiltration rate of the bioretention facility.
Additionally, for sites with high infiltration rates (or where recharge is desired), pretreatment is required to protect groundwater quality.
The proposed recharge basin location was specifically selected due to the occurrence of relatively high infiltration rates in that area and a thinning out of the Corcoran clay layer, and thus may not provide adequate treatment in order to protect groundwater quality, especially considering that it is recharging to the lower aquifer that serves as the City’s primary source of drinking water. This would be a significant impact to groundwater quality. The following mitigation measure requires the Zacharias Planning area to incorporate stormwater quality BMPs similar to those that are required for the Baldwin Planning Area (because that portion does ultimately drain to Solado Creek).

Groundwater Supply and Recharge
Impact HYD-2: Would buildout of the project substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? Impact Analysis
This impact addresses groundwater supply and recharge.
Groundwater Supply
The City of Patterson will supply potable and non-potable water to the project. The City obtains all their water supply from groundwater and does not currently purchase or import water or have any current plans to do so in the future. The City anticipates developing new well heads within the Zacharias planning area to extract potable water from the lower aquifer in support of increased water demand due to the project, when project buildout requires it. All parks and public landscape space will be irrigated with non-potable water.
The Delta-Mendota groundwater subbasin, from which the City’s potable water is extracted, was classified as a critically overdrafted aquifer under SGMA in 2014. SGMA required that GSAs in critically overdrafted areas prepare and submit a GSP by January 31, 2020 with measures necessary to attain sustainable conditions in those subbasins by 2040. The City of Patterson formed a GSA and became a member of the Northern & Central Delta-Mendota GSP Group. The group submitted a draft GSP to the state in January 2020 (GSP 2019) that outlines projects and management actions to halt long-term declines in groundwater storage in both the upper and lower aquifers.
On a regional scale, primary groundwater management measures that would be implemented via the GSP include increased conservation and efficiency, increased groundwater recharge, increased water recycling and reuse, integrated groundwater management with other water resources such as stormwater, and lower aquifer pumping limitations relative to water levels at key index wells to minimize inelastic land subsidence (GSP 2019).
On a local scale, the City of Patterson assessed future water demand needs in recent water management planning documents (WMP 2018; UWMP 2016). The City selected a portfolio for water

The WMP also evaluated supply options that included import or purchase of water, but deemed that they are not necessary at this time and would require additional study if they were to eventually be implemented in coming years. The WMP concluded that, with the implementation of planned projects and conservation efforts, the City’s potable and non-potable water supply is sufficient to support expected growth over the 30-year planning period (including growth associated with development at the project site), and that expected water usage would not significantly impact groundwater resources in the subbasin from which the City draws its supply.
The total annual groundwater pumping capacity of the City is 7,550 AFY (as of 2018), with about 3,318 AFY of that capacity currently being utilized (WSA 2020). Potable water demand in 2018 was 3,102 AFY and non-potable was 216 AFY. An Operational Yield Study (WMP 2018) was conducted to estimate the volume of groundwater that the City could safely extract from the Delta-Mendota Subbasin. The study concluded that the City could construct additional groundwater wells to increase its pumping capacity to the range of 10,000 – 12,000 AFY without impacting current groundwater pumping infrastructure and without significantly impacting the use of groundwater resources in the area surrounding the City’s Sphere of Influence (which would include the Zacharias planning area once annexed). Under the City’s selected future supply portfolio, it is assumed that the City would construct enough potable wells to produce up to 10,115 AFY at buildout (WAS , 2020), which would be on the low side of the range found to be without significant impacts to groundwater infrastructure or groundwater resources. Accordingly, increased water demand from this project (which has been included in the City’s long-term demand projections) will not result in significant impacts to groundwater supply relative to other users in the area. Additionally, as discussed further below, the proposed project would contribute to recharge of the lower aquifer through infiltration of stormwater runoff from the project site, contributing to sustainable operation of the City’s potable groundwater supply, as well as having a markedly smaller upper aquifer water demand.
Total existing water demand for the project area was estimated to be 5,384 AFY, of which 5,370 AFY was estimated as the maximum non-potable groundwater withdrawals for agricultural use (drawn from the upper aquifer) and 14 AFY was residential potable water use (WSA 2020). Groundwater withdrawals were lower in years when surface water supplies were available. 1 Total predicted water
demand of the project at full build-out is projected as 2,159 AFY for an average water year, a net reduction compared to existing conditions (WSA 2020).
Project-Specific Potable Water Supply
Even though overall water use would decrease under post-project conditions, the amount of potable water needed would increase. Projected potable water demand would be 1,560 AFY, an increase in demand of 1,546 AFY from the lower aquifer relative to existing conditions. In order to support the City’s goal to sustainably manage the underlying groundwater resources, the project has plans to pump all stormwater runoff to a newly established recharge basin located west of the project, centered within the footprint of an abandoned gravel-mining quarry adjacent to the south side of 1 Surface water deliveries to agricultural lands in the Zacharias planning area ranged from approximately 750 AFY to 2300 AFY between 2009-2019 (pers. comm. Maria Encinas, City of Patterson via information supplied by West Stanislaus Irrigation District).

Hydrogeological studies by KSA indicate that recharge basin(s) near the Delta-Mendota Canal would recharge to the lower aquifer.
Thus, the recharge basin site selected for this project (in coordination with the City) is expected to help replenish the City’s potable water supply more so than it would if recharge were concentrated at the project site itself, where infiltration to the lower aquifer would be impeded by the presence of the Corcoran clay confining layer.
The WSA (2020) concluded that the City of Patterson has an adequate groundwater supply to serve the project area while also serving the City’s current customers. Recommendations to reduce projected demand include additional conservation programs, requiring high water efficiency standards for all fixtures, appliances and industrial processes installed in the project area, and consideration of requiring the use of drought tolerant landscaping or requiring other actions to improve landscape efficiencies. Furthermore, the WSA recommended that the City and project stakeholders confirm phasing of the development and coordinate with the GSA group implementing the Northern & Central Delta-Mendota Region GSP so that the City’s supply projects can be implemented appropriately to ensure a reliable supply for all of its customers through the project build-out.
Project-Specific Non-Potable Water Supply
In addition to the potential impacts to potable water sources discussed above, the project may also affect water supply in the upper aquifer (non-potable supply). The projected non-potable water demand of the project is expected to be 599 AFY, a decrease in demand of 4,771 AFY from the upper aquifer, water which could be used elsewhere, or which would support sustainable management through net pumping reductions within the upper aquifer. Although diverting stormwater runoff from the project site up to the proposed recharge basin (and ultimately to the lower aquifer) would decrease the amount of water available for infiltration to the upper aquifer directly beneath the site, the potential estimated reduction in upper aquifer recharge is considerably less than the decrease in pumping from the upper aquifer (4,771 AFY) that would result from the conversion of the project site from primarily agricultural (non-potable) water use to urban (potable) water use.
The WSA (2020) provides a simplified estimation of the amount of stormwater that would have the potential to recharge the upper aquifer of 1,185 AFY (but which is to be pumped to the recharge basin instead as a result of an agreement between the project applicant and the City, to better support the City’s potable water supply), based on the project area and the City’s annual average rainfall of 11 inches per year. This volume serves as the upper-bound of the average long-term change in recharge to the upper aquifer on the project site itself. In addition, Debler and Chapman (2020) estimated an average annual runoff volume of 598 AFY based on Zacharias project area, mean annual precipitation and a mean runoff coefficient per basin area, which yields a more likely average long-term volume of potential recharge to the upper aquifer (excluding project plans to pump stormwater to the recharge basin). Some of that stormwater runoff volume may still recharge to the upper aquifer, through infiltration in treatment BMPs or within the distributed detention/retention basins located within the project site.
It is important to note that the WSA (2020) makes the assumption that the project will retain and infiltrate all stormwater on-site into the upper aquifer, which differs from the assessment herein. The

Still, as discussed above, this difference from the analysis in the WSA does not conflict with the ultimate conclusion that there will not be a significant impact to water supply in the upper aquifer.
Summary
In summary, based on the discussion above, the net effect of the project would be to:
Reduce pumping from the upper aquifer as a result of conversion to urban uses; Reduce recharge to the upper aquifer as a result of diverting stormwater runoff to the loweraquifer recharge basin, but at a substantially smaller average annual rate than the increase associated with #1 above;
Increase usage of potable water by 1,546 AFY (provided by the City), but still within the acceptable range of operational limits of the City’s facilities and without impacting the use of groundwater resources in the area surrounding the City (per the Operational Yield Study in the WMP, 2018);
Increase recharge of water to the lower aquifer to help offset the increase in potable water demand at the project site, and to help the City achieve its sustainability goals under the SMGA GSP.
In coordination with the City of Patterson, the project has identified conservation strategies that reduce potable water demand and aquifer recharge strategies that support lower aquifer recharge to optimize potable water supply. Required implementation of conservation measures and other potential supply and/or recharge activities would further support sustainable groundwater management of the basin. In concert with implementation of SGMA requirements, the above project plans and City requirements would reduce the potential impacts related to groundwater quantity and recharge to a less than significant level.

Impact HYD-3: Buildout of the Master Plans may alter the existing drainage pattern of the site that may create erosion or downstream flooding problems.
Impact Analysis
This impact addresses drainage issues including erosion and siltation, the stormwater drainage system, and on-site and off-site flooding.
Erosion or Siltation
Construction-related impacts relating to erosion or siltation both on and off-site are discussed in Impact HYD-1. Implementation of the project-specific SWPPP, in compliance with the Central Valley RWQCB Construction Permit requirements, would mitigate the impact related to erosion and downstream flooding during project construction. The resulting construction-related impacts would be less than significant. No further mitigation is required.
Runoff and potential pollution (including sediment) generated by newly impervious surfaces, as discussed in Impact HYD-1, will be mitigated through implementation of Mitigation Measures HYD1a and HYD-1b such that impacts related to high flows, erosion or increased pollutant levels in downstream waterbodies would be avoided. The resulting post-construction related impacts related to potential hydromodification effects would be less-than-significant. No further mitigation is required.
Stormwater Drainage System
The proposed project would increase the amount of impervious surfaces within the project area by as much as 460 acres, which is likely to increase the amount and rate of surface-water runoff and result in flooding within or downstream of the project site if not adequately controlled. The project includes installation of a new storm drainage system consisting of retention and detention basins, lakes, bioswales, inlets, and underground piping that would be designed to capture and detain runoff from the project area in compliance with City of Patterson Standard Specifications, Section 8, Storm Drainage. Compliance with City development standards would ensure that the proposed storm drainage system is appropriately designed and implemented in order to prevent flooding onsite, as the project applicant would be required to submit storm drainage master plans to the City of Patterson for review and approval prior to permit issuance such that impacts would be avoided.
Zacharias Master Plan
Balance Hydrologics assessed the potential for flooding in the Zacharias Master Plan area. An accompanying Technical Memo is provided in Appendix H.
The storm drainage control facilities will be implemented within the Zacharias Master Planning Area with the intention of achieving following:
Flood Control for the 10-year, 24-hour storm (detention basins) for individual areas, and corresponding Supervisory Control and Data Acquisition (SCADA) outlet devices and lines.

The FEMA Solution for retaining the 100-year FEMA floodplain (183 acre-feet of runoff based on the 100-year Flood Depths for Del Puerto Creek Hydraulic Model by Balance Hydrologies, Inc.) for the Zacharias Master Planning Area.
Recharge of the stormwater runoff into the lower aquifer groundwater table below to Corcoran Clay Layer, where the City’s potable water wells draw water from.
The storm drainage system will utilize multiple stages of storage involving both detention and retention purposes for the project site. The Zacharias Ranch Planning Area will utilize a mix of detention (designed for 10-year, 24-hour storage) and retention (designed for 100-year, 24-hour storage) basins. Both types of basins will have SCADA gravity outlet systems with corresponding pipelines to meter the flow out of the basins. The retention basins will be designed to drain stormwater through the SCADA system for up to a 10-year, 24-hour storm event, with the basin retaining and percolating the runoff for corresponding drainage areas for any storm event exceeding a 10-year, 24-hour event; up to a 100-year, 24-hour event. The TPF Development and Keystone Ranch Planning Areas will each have a retention basin with corresponding SCADA outlet systems draining to the lakes. The Ivy Rose Gardens Planning Area will have a detention basin with a pump station and force main for metering water out of the basin to the lakes. The pump station will be designed for a minimum 1360 gallons per minute (gpm) flowrate.
The Lakeside Hills Development Area will have a series of wet basin lakes for flood control. These lakes will be designed to hold the entirety of the 100-year, 24-hour storm event for the Lakeside Hills Development Area, as well as the difference between the 100-year and 10-year events for the detention basins within the Zacharias Ranch and Ivy Rose Gardens Planning Areas. This will achieve the ultimate goal of storing the 100-year, 24-hour storm event for the entirety of the Zacharias Master Planning Area between the lakes and retention basins. Consequently, the lakes will store the 10-year, 24-hour storm event for the entire Zacharias Master Planning Area, as both the detention and retention basins will drain to the lakes for any storm event equal to or below the 10-year event.
The lakes will drain to a pump station that will meter out through a force main to the FEMA Basin.
The pump station will have a maximum output of 2000 gpm for draining the lakes. Note that the dry basins (detention basins and retention basins) are designed for a maximum 48-hour drawdown period, whereas the lakes are not required as such.
The FEMA Basin will act as a solution to the FEMA requirement to divert or retain the 100-year flood runoff for the Zacharias Master Planning Area. The basin will be designed with a two-stage system for an upper reservoir and lower reservoir area. The lower reservoir will be utilized during smaller storms for a combination of runoff from the floodplain, and for intermediate storage for the stormwater pumped from the lakes. The upper reservoir will be reserved for major storms where floodplain runoff exceeds the lower reservoir. The basin will be designed to percolate the FEMA floodplain runoff within a 48-hour drawdown period. The basin will have an inlet structure attached to the force main coming from the wet basin lakes, and an outlet structure with corresponding pump station. The basin pump will operate at a maximum 2000 gpm flowrate, so as to drain the

The outlet force main from the FEMA Basin will flow to the Recharge Basin Facility, to the northwest of the Zacharias Master Planning Area. The Recharge Basin Facility will be located at the existing rock quarry, where a location has been designated by the City of Patterson. The location noted does not have the Corcoran Clay Layer (an impervious layer separating the potable and non-potable water tables), and instead infiltrates directly into the lower aquifer. The overall Zacharias Master Planning Area will have an annual runoff of 604 acre-feet per year, or 0.539 million gallons per day. The vast majority of this stormwater will be recharged through the Recharge Basin Facility.
The project area facilities provided will be subject to the most up-to-date version of the City of Patterson’s Multi-Agency Post Construction Manual, and the corresponding Phase II Permit requirements for stormwater. The developers for each project area will be responsible for meeting these requirements within their project areas (Zacharias Ranch, TPF Development, Keystone Ranch, Lakeside Hills, and Ivy Rose Gardens Planning Areas) and maintaining such facilities as required.
The Storm Drain Master Plan for the project area storm drain facilities is shown in Section 2, Project Description, Exhibit 2-9a. The FEMA Solution Basin and corresponding facilities is shown on Exhibit 2-9b, and the recharge Basin Facility and corresponding force main is shown on Exhibit 2-9c.
Analysis
Stormwater within the Zacharias planning area up to the 100-year event would be retained on-site and/or pumped up to a newly established groundwater recharge basin. The planning area would have a series of basins sized to accommodate the 10-year runoff volume for detention basins and the 50-year runoff volume for retention basins, per City of Patterson flood control requirements.
Runoff would be conveyed via storm drains within 48 hours to two centralized lake features that would be sized to accommodate the 50-year runoff volume. In a 100-year event, runoff beyond the 50-year holding capacity would be conveyed from the lakes via pumping approximately 2 miles west, upslope along Zacharias Road, to the off-site recharge basin.
For the Zacharias planning area, all stormwater runoff up to the 100-year event would be retained on-site and/or pumped to the planned recharge basin within a new drainage system, which would result in less-than-significant impacts to flooding potential. However, the proposed stormwater drainage system in the Zacharias planning area includes two lakes that would be fitted with pumps with the capacity to move stormwater runoff greater than the 50-year storage capacity of the lakes to the upslope recharge basin. A pump system failure could constitute a significant impact to onand/or off-site flooding. The following mitigation measure requires the Zacharias planning area to develop an emergency action plan for pump failure.
Mitigation Measure HYD-3a requires the first Zacharias applicant to develop an emergency action plan for pump failure to prevent downstream inundation. Implementation of Mitigation Measure HYD-3a would reduce the potential impact of flooding in the Zacharia planning area to a less than significant level.

In the Baldwin planning area, storm drains, inlets, and underground piping would convey runoff to stormwater basins within the project site. The basins will be sized to accommodate the 10-year runoff volume per City of Patterson flood control requirements and would connect to the existing municipal storm drainage system.
On-site Flooding
The proposed project would increase impervious surfaces within the project site by as much as 460 acres and would build storm drain networks consistent with the new project configuration. As discussed in Impact HYD-2, preliminary drainage plans indicate that stormwater runoff in the Zacharias planning area will be retained or detained in a series of on-site bioswales, basins and lakes sized to accommodate a 100-year flood event, and in the Baldwin planning area a basin would accommodate a 10-year flood event and CTE CAL, Inc. performed percolation tests, in accordance with Stanislaus County requirements for preparing and pre-saturating the soil in the test holes, to develop recommended drainage design infiltration rates in the proposed Zacharias planning area for the detention/retention basins, lakes, flood control basin and recharge basin. Drainage infrastructure for the project site will be completely new and designed for a capacity specific to meet the needs of the project site and in compliance with City of Patterson flood control requirements.
Zacharias Master Plan
Portions of the Zacharias planning area are designated as FEMA Zone AO, which is defined as subject to flood depths of 1 foot in a 100-year flood event (1 percent annual chance flood hazard). A FEMA Letter of Map Revision (LOMR) for the Villages of Patterson community, located to the east of the planning area across State Route 33 was submitted, and a revision approved (dated August 3, 2018), to change the FEMA designation for the community from Zone AO to Zone X (shaded), which removed it from the 100-year flood hazard area.
The Villages of Patterson remapping effort suggested that the Zacharias planning area subject to FEMA Zone AO would also be substantially reduced as a result of additional modeling that would show fewer flooding effects than the currently effective FEMA flood map of the area. New modeling was conducted that focused on flooding potential to the Zacharias planning area. Results estimated that flows above 1,600 cfs would overtop Del Puerto Creek to the south toward the planning area; the 100-year overflow volume was estimated as 182 AF. Overflows onto the south overbank area were predicted to be generally well-dispersed over the relatively uniform terrain with maximum flood depths generally less than 2 feet.
A proposed flood control retention basin along the Del Puerto Creek south overbank flow path would consist of an excavated area immediately north of Zacharias Road, located within the flow path and sized to retain the 182 AF of overflow from Del Puerto Creek that is predicted to occur during the 100-year flood event. The basin would cover an area of approximately 27 acres and would be sized to yield a total storage volume of approximately 189 AF with one foot of free board.
Berms and swales would be utilized to hold overbank flows to the north of Zacharias Road and direct flows into the flood control basin. Interception of overbank flow would essentially eliminate the flood hazard from Del Puerto Creek within the Zacharias planning area and would have the

Baldwin Master Plan
The vast majority of the Baldwin planning area lies outside of any FEMA flood designation; the eastern edge of the planning area falls just within the western edge of a predicted Salado Creek Zone X area, defined as an area with 0.2% annual chance (500-year) flood hazard. Baldwin Road would be improved along the eastern edge of the planning area to accommodate planned traffic patterns (AMG, 2020), which would serve to eliminate the potential for Zone X flows to impact the area.
Off-site Flooding Potential
Zacharias Master Plan
In the Zacharias planning area, all stormwater up to the 100-yr event would be detained, retained and/or pumped to the recharge basin (Debler and Chapman, 2020), which would result in very little to no runoff leaving the site; this would improve downstream conditions relative to current conditions.
The proposed flood control basin would reduce the potential for flooding from Del Puerto Creek overbank flow into the project area as well into as existing portions of the City to the south and east, as described above. A planned FEMA LOMR study and application is expected to result in removal of all Zone AO areas within the Zacharias planning area, as well as portions of the City to the south and east, from the FEMA FIRM.

In the Baldwin planning area, all stormwater up to the 10-year event would be detained/retained onsite in compliance with City requirements and then would drain north through the existing storm drain/irrigation lateral along Baldwin Road to Sperry Avenue, which could result in a significant impact to the downstream storm drain system, as existing Salado Creek capacity is limited from the Delta Mendota Canal north to the southern limit of existing residential development.
Implementation of site design and treatment measures mandated by the Phase II Permit and the City would have the effect of reducing and attenuating volumes and rates of runoff.
Mitigation Measure HYD-3b requires applicants to prepare and submit drainage plans that demonstrate that new development does not create downstream flooding problems.
Implementation of Mitigation Measure HYD-3b would reduce the potential impact of stormwater runoff from the Baldwin planning area to the downstream storm drain system to a less than significant level.
Summary
In summary, based on the discussion above, the net effect of the project would be to:
Installation of an all new stormwater drainage system that meets or exceeds City flood control requirements and reduces the impact of on-site flooding to a less-than-significant level.

This stormwater plan complies with and exceeds City flood control requirements and would result in improved conditions downstream relative to current conditions.
- Implementation of mitigation measure HYD-3a in support of a pump failure action plan would bring potential impacts to a less-than-significant level.
The proposed flood basin would be designed to collect the Del Puerto 100-yr overbank flow event, thus effectively reducing the potential for flooding to the Zacharias planning area to a less-than-significant level and resulting in a net improvement to flood conditions within the City areas to the south-southwest of the planning area.
In the Baldwin planning area, all stormwater up to the 10-yr event would be detained on-site in compliance with City flood control requirements and then released to City stormwater system.
- Implementation of Mitigation Measure HYD-3b in support of detention/retention and/or metering of stormwater runoff up to the 100-year event would bring potential impacts to a less-than-significant level.
As summarized above, new stormwater infrastructure compliant with City requirements would eliminate potential concerns for exceedance of storm drain system capacity on the project site and a flood control basin would eliminate potential on-site or off-site flooding concerns. Implementation of the above actions in compliance with City requirements would reduce potential drainage and flooding impacts to a less than significant level.
Level of Significance Before Mitigation
Potentially significant impact.
Mitigation Measures
MM HYD-3a Prior to operation of the stormwater lift station that would serve the Zacharias Master Plan, the applicant shall prepare and submit an emergency action plan for lift station failure to the City of Patterson for review and approval. The plan shall outline pump and power redundancy plans, potential flow routing, and other potential actions to be taken if pump failure occurs. The approved plan shall be implemented.
MM HYD-3b Prior to issuance of a grading permit for the Baldwin Master Plan, the project applicant shall submit stormwater calculations to the City for approval that confirm that increases in downstream flow rates for storms greater than the 10-year event up to the 100-year event would not cause downstream flooding issues, or, submit plans for adequate additional detention, retention and/or metering to mitigate stormwater runoff to comply with the City Storm Drain Master Plan up to the 100- year peak flow event.
Level of Significance After Mitigation
Less than significant impact.

Impact HYD-4: Buildout of the Master Plans would not result in release of pollutants due.
Impact Analysis
This impact addresses threshold of significance questions (d), focused on the potential for development activities to increase the risk of release of pollutants due to susceptibly to downstream flooding, erosion, or elevated pollutant levels as a result of increased impervious surfaces, which could lead to an increase in pollutant-laden runoff volume or peak flows.
Construction-related impacts relating to erosion or siltation both on and off-site would be avoided in compliance with the SWPPP as discussed in Impact HYD-1. Post-construction implementation of stormwater treatment BMPs in compliance with the Phase II Permit are also discussed in Impact HYD-1. The new stormwater drainage system will be designed to capture and detain all runoff from the project area in compliance with City of Patterson standards as discussed in Impact HYD-3.
Furthermore, implementation of the flood control basin as discussed in Impact HYD-3 would eliminate the risk of project area inundation from overbank flooding from Del Puerto Creek.
Implementation of these required strategies would result in avoidance of impacts related to increased pollutant levels in flood hazard zones. Flood hazard impacts causing an increased risk of pollutants associated with development in this area would be less than significant.
Level of Significance Before Mitigation
Less than significant impact.
Mitigation Measures
No mitigation is required.
Level of Significance After Mitigation
Less than significant impact.
Conflicts With Water Management Plans
Impact HYD-5: Buildout of the Master Plans would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan.
Impact Analysis
This impact addresses conflicts with an adopted water management plan.
Water Quality Control Plan
The currently effective Central Valley RWQCB Basin Plan (2018) includes the Delta-Mendota Canal Hydrologic Unit 541.10 Patterson, a sub-basin of the San Joaquin River Hydrologic Unit. Beneficial uses designated for the Patterson sub-unit include municipal and domestic supply, irrigation, stock watering, recreation-1 (contact), recreation-2 (other noncontact), freshwater habitat (warm), and wildlife habitat. The Basin Plan designates or establishes such beneficial uses of waters to be protected, water quality objectives to protect those uses, and a program of implementation needed for achieving the objectives. Water quality objectives are defined as limits or levels of water quality

The implementation of a SWPPP during construction activities in compliance with the NPDES Construction Permit as described in Impact HYD-1 and implementation of a SWQMP in compliance with the Phase II permit as described in Impact HYD-1 brings the project into compliance with the Basin Plan and as such does not conflict with or obstruct implementation of a water quality control plan, and the potential impact would be less than significant.
Sustainable Groundwater Management Plan
The State of California established a legislative framework for sustainable groundwater management, the Sustainable Groundwater Management Act (SGMA), that became law on September 16, 2014. SGMA requires governments and water agencies to halt overdraft and bring groundwater basins into balanced levels of pumping and recharge within a specified timeframe.
GSAs within the Delta-Mendota Subbasin, which was listed as critically overdrafted, were required to submit GSPs by January 2020.
The City of Patterson created a GSA and joined with other GSAs to form the Northern & Central Delta-Mendota GSP Group. A draft GSP was submitted to the state in January 2020 that outlines projects and management actions to halt long-term declines in groundwater storage in both the upper and lower aquifers as discussed in Impact HYD-2. As also discussed in Impact HYD-2, project implementation of an infiltration basin to recharge stormwater into the lower aquifer, and a significant decrease in the amount of pumping from the upper aquifer support, the goals of the GSP.
The project is in compliance with City and SMGA requirements, and as such would have a less than significant impact on the sustainable groundwater management plan.
Level of Significance Before Mitigation
Less than significant impact.
Mitigation Measures
No mitigation is required.

3.10 - Land Use
3.10.1 - Introduction
This section describes the existing land use context and potential effects from project implementation on the site and its surrounding area. Descriptions and analysis in this section are based on site reconnaissance, review of the City of Patterson General Plan, the Patterson Municipal Code, the Stanislaus County General Plan, and Stanislaus Local Agency Formation Commission (LAFCo) procedures, and the proposed Baldwin and Zacharias Master Plans.
3.10.2 - Environmental Setting
Land Use
Baldwin Master Plan
The Baldwin Master Plan area contain agricultural land (orchards). A cluster of residential and agricultural buildings is present at the terminus of Baldwin Road. Exhibit 2-3 provides a photograph of this area.
Zacharias Master Plan
The area west of Baldwin Road contains agricultural land (orchards and row crops). A cluster of residential and agricultural buildings is present along Baldwin Avenue. Lateral Six South, a Patterson Irrigation District (PID) canal, runs south-to-north near Rogers Road.
The area east of Baldwin Road contains agricultural land (row crops) west of the PID Lateral M canal and the “Ranchette” residential area on the east side. PID Lateral Five South, an irrigation canal, runs south-to-north along Baldwin Road.
The approximately 137-acre Ranchette Triangle consists of 31 parcels, 24 of which support a residence. Of the 24 parcels with a residence, 15 of them are residential only (most of which are 1 acre or less). The largest parcels (4 acres or more) support most of the agricultural acreage. Six of the parcels totaling 47.73 acres are encumbered by active Williamson Act Contracts.
Exhibit 2-3 provides a photograph of this area.

Land Use Designations
County of Stanislaus
Baldwin Master Plan
The Stanislaus County General Plan designates the Baldwin Master Plan area as “Agriculture.” The Stanislaus County Zoning Ordinances zones the Baldwin Master Plan area as “General Agriculture (A2).” Zacharias Master Plan
The Stanislaus County General Plan designates the area west of the PID canal as “Agriculture.” The Stanislaus County General Plan designates the area east of the canal as “Urban Transition.” The Stanislaus County Zoning Ordinances zones the area west of the PID canal as “General Agriculture (A-2).” The Stanislaus County Zoning Ordinances zones the area east of the PID canal as “General Agriculture (A-2-10).”
City of Patterson
The City of Patterson General Plan designates the Master Plan areas as “Low Density Residential,” which is a non-binding designation. This is also a “placeholder” land use designation the City has assigned to unincorporated areas around the Patterson city limits and does not necessarily signify that the City intends for all of this land to be developed as low density residential.

The approximately 137-acre Ranchette Triangle is within the Patterson Sphere of Influence. All other portions of the Master Plan area are outside the Sphere of Influence.
3.10.3 - Regulatory Framework
Local
City of Patterson
General Plan
The City of Patterson General Plan provides a blueprint for growth within the Patterson city limits and Sphere of Influence. The General Plan was adopted by the Patterson City Council on November 30, 2010. The General Plan contains the following topical chapters: Land Use, Housing, Community Design, Economic Development, Circulation, Air Resources and Climate Change, Public Services, Parks, Recreation and Cultural Resources, Health and Safety (Noise, Safety), Natural Resources (Conservation and Open Space), and Administration and Implementation. The General Plan includes the goals, policies, standards, implementation programs, quantified objectives, a draft land use diagram, and a draft circulation plan diagram that constitute the formal policy of the City of Patterson for land use, development, and environmental quality.
Municipal Code
The Patterson Municipal Code establishes specific regulations for land use activities and development within the City of Patterson. Title 18, Zoning, contains the City of Patterson Zoning Code, which promotes and protects the public health, safety, peace, morals, comfort, convenience, and general welfare of the public, and insures the orderly development of the City.
Stanislaus Local Agency Formation Commission
Stanislaus LAFCo reviews proposals for the formation of new local governmental agencies and for changes in the organization of existing agencies with Stanislaus County. Stanislaus LAFCo regulates, through approval or denial, boundary changes proposed by other public agencies or individuals.
Boundary changes are assessed against the criteria set forth in California Government Code Section 56668, which establishes factors LAFCo agencies must use in reviewing annexation proposals.
3.10.4 - Methodology
FCS evaluated the potential for land use impacts through site reconnaissance and review of applicable land use policy documents. FCS personnel performed site reconnaissance on the Master Plan areas and surrounding land uses on multiple occasions in 2018. Photographs were taken of the Master Plan areas and surrounding land uses to document existing conditions. FCS reviewed the City of Patterson General Plan, the Patterson Municipal Code, and the Stanislaus County General Plan to identify applicable policies and provisions that pertain to the proposed Master Plans.

3.10.5 - Thresholds of Significance
According to the CEQA Guidelines’ Appendix G Environmental Checklist, to determine whether land use and planning impacts are significant environmental effects, the following questions are analyzed and evaluated. Would the project:
a) Physically divide an established community?
b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? Please note that the second threshold is evaluated in Impacts LU-2, LU-3, and LU-4 in the interests of distinguishing between the General Plan, Municipal Code, and LAFCo policy.
3.10.6 - Project Impacts Mitigation Measures
This section discusses potential impacts associated with the proposed Master Plan and provides mitigation measures where necessary.
Divide an Established Community
Impact LU-1: Buildout of the proposed Master Plans would not physically divide an established community.
Impact Analysis
This impact assesses whether the proposed Master Plans would physically divide an established community. For the purposes of this evaluation, an established community is defined as a grouping of occupied dwelling units inhabited by persons who would be involuntarily displaced by the buildout of the Master Plans.
Baldwin Master Plan
Buildout of the Master Plan would be limited to the Master Plan boundaries. No off-site improvements would be required that would have the potential to divide an established community.
The existing cluster of structures would be removed. This cluster would not constitute an “established community.” Moreover, their removal would be at the behest of their owner. Impacts would be less than significant.
Zacharias Master Plan
The 1,160 acres of the Master Plan area that excludes the Ranchettes contains agricultural land.
There are two clusters of residential and agricultural structures within this area that would ultimately be removed as the Master Plan builds out. These two clusters of structures would not constitute an “established community.” Moreover, their removal would be at the behest of their owners. Thus, buildout of this portion of the Master Plan area would not constitute the division of an established community.
The 137-acre Ranchette Triangle contains more than 30 separate parcels. The Master Plan allows property owners to continue existing land use activities after annexation. Thus, any change in land

The East-West Connection would cross through the Ranchette area. The alignment of this road follows an existing property line (west of Ward Avenue) and through a vacant land associated with a medical office building (east of Ward Avenue). The Master Plan applicant team have met with the affected property owners and found that there is preliminary support for this connection. The development of this roadway would not require removal of any structures. Moreover, it would allow for a direct connection from Ward Avenue and SR-33 to the Zacharias Master Plan area, which would improve circulation within Patterson. Impacts would be less than significant.
Level of Significance Before Mitigation
Less than significant impact.
Mitigation Measures
No mitigation is necessary.
Level of Significance After Mitigation
Less than significant impact.
General Plan Consistency
Impact LU-2: Buildout of the proposed Master Plans would not conflict with the City of Patterson General Plan.
Impact Analysis
This impact assesses whether the proposed Master Plans would conflict with the General Plan.
Baldwin and Zacharias Master Plan
General Plan Amendment
The Master Plan areas are currently located outside the City of Patterson’s Sphere of Influence. As part of the project’s discretionary approvals, a General Plan Amendment would be processed to expand the City’s Sphere of Influence to encompass the 1,286-gross-acre Master Plan areas to be coterminus with the proposed annexation request. This General Plan Amendment is expected to occur concurrently with the annexation/pre-zoning approvals. Note that Stanislaus LAFCo would also be required to approve the Sphere of Influence expansion request.
This General Plan Amendment would ensure that the City of Patterson’s jurisdictional boundaries are in conformance with state requirements. Furthermore, because the General Plan contemplates annexation of the entire project site at some future, undetermined date, adjusting the Sphere of Influence to be co-terminus with expanded city limits would not be in conflict with any aspect of the General Plan. Impacts would be less than significant.

development strategy
embodied in the Patterson
General Plan is based on the
premise that the outward
urban expansion of the City
will occur through the
incremental annexation and
development of “complete”
neighborhoods, incorporating
the following characteristics:
a. A mix of housing products
and densities serving the
broadest range of
households, incomes and
ages;
b. A neighborhood center

Consistent: The Master Plan
allows a mix of single-family
housing products, parks, and a
trail system. Because the
Master Plan would represent
the southern-most residential
development area in the City
of Patterson, non-residential
uses are neither feasible nor
desirable because of their
distance from main
thoroughfares
Consistent: The Master Plan
allows a range of housing
products including singlefamily and multi-family, light industrial uses, commercial
uses, a lakeside mixed use
activity area, two schools,
parks, and a trail system.

Impact Analysis
This impact assesses whether the proposed Master Plans would conflict with the Municipal Code.
Baldwin and Zacharias Master Plans
The proposed Baldwin Master Plan and Zacharias Master Plan each establishes the regulatory framework that would govern buildout. The Master Plans are intended to supplement the General Plan by establishing area-specific development standards and design guidelines that will apply to new development within the plan boundaries. The Master Plans provide specific area-wide development standards which supplement municipal codes, but since the lands would be annexed into the city, Municipal Code requirements would still apply in other respects, where applicable.
The proposed Master Plans would facilitate the orderly and planned development of the proposed land uses within the Master Plan boundaries. The Master Plan requires structures to be developed in accordance with a set of design standards and guidelines to encourage sensitive, integrated, innovative and sustainable project designs. In summary, the proposed Master Plans comply with all applicable requirements of the Patterson Municipal Code.

The proposed Master Plan would require approval from Stanislaus Local Agency Formation Commission (LAFCo) for annexation of the Baldwin and Zacharias Master Plan areas into the Patterson city limits. Pursuant to state law and Stanislaus LAFCo procedures, a city’s corporate limits must be at a minimum co-terminus with its Sphere of Influence. The applicant is seeking to expand the Sphere of Influence in a manner that renders it co-terminus with the city limits contemplated by the annexation.
As such, this EIR will address project consistency with the criteria set forth in California Government Code Section 56668 (also known as the Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000), which establishes factors LAFCo agencies must use in reviewing adjustments to jurisdictional boundaries.

3.11 - Noise
3.11.1 - Introduction
This section describes the existing noise setting and potential effects from project implementation on the site and its surrounding area. Descriptions and analysis in this section are based on noise modeling performed by FirstCarbon Solutions (FCS). The noise modeling output is included in this Draft EIR as Appendix G.
3.11.2 - Environmental Setting
Characteristics of Noise
Noise is defined as unwanted sound. Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm or when it has adverse effects on health. Sound is produced by the vibration of sound pressure waves in the air. Sound pressure levels are used to measure the intensity of sound and are described in terms of decibels. The decibel (dB) is a logarithmic unit, which expresses the ratio of the sound pressure level being measured to a standard reference level. The 0 point on the dB scale is based on the lowest sound level that the healthy, unimpaired human ear can detect. Changes of 3 dB or less are only perceptible in laboratory environments. Audible increases in noise levels generally refer to a change of 3 dB or more, as this level has been found to be barely perceptible to the human ear in outdoor environments. Only audible changes in existing ambient or background noise levels are considered potentially significant.
A-weighted decibels (dBA) approximate the subjective response of the human ear to a broad frequency noise source by discriminating against very low and very high frequencies of the audible spectrum. They are adjusted to reflect only those frequencies that are audible to the human ear.
Because decibels are logarithmic units, they cannot be added or subtracted by ordinary arithmetic means. For example, if one noise source produces a noise level of 70 dB, the addition of another noise source with the same noise level would not produce 140 dB; rather, they would combine to produce a noise level of 73 dB.
Noise Descriptors
There are many ways to rate noise for various time-periods, but an appropriate rating of ambient noise affecting humans also accounts for the annoying effects of sound. Equivalent continuous sound level (Leq) is the total sound energy of time-varying noise over a sample period. However, the predominant rating scales for human communities in the State of California are the Leq and Community Noise Equivalent Level (CNEL) or the day-night average level (Ldn) based on dBA. CNEL is the time-varying noise over a 24-hour period, with a 5 dBA weighting factor applied to the hourly Leq for noises occurring from 7:00 p.m. to 10:00 p.m. (defined as relaxation hours) and a 10 dBA weighting factor applied to noise occurring from 10:00 p.m. to 7:00 a.m. (defined as sleeping hours).
Ldn is similar to the CNEL scale but without the adjustment for events occurring during the evening hours. CNEL and Ldn are within one dBA of each other and are normally exchangeable.
Other noise rating scales of importance when assessing the annoyance factor include the maximum noise level (Lmax), which is the highest exponential time-averaged sound level that occurs during a

The noise environments discussed in this analysis are specified in terms of maximum levels denoted by Lmax for short-term noise impacts. Lmax reflects peak operating conditions and addresses the annoying aspects of intermittent noise.
Noise Propagation
From the noise source to the receiver, noise changes both in level and frequency spectrum. The most obvious is the decrease in noise as the distance from the source increases. The manner in which noise reduces with distance depends on whether the source is a point or line source, as well as ground absorption, atmospheric effects and refraction, and shielding by natural and manmade features. Sound from point sources, such as an air conditioning condenser, a piece of construction equipment, or an idling truck, radiates uniformly outward as it travels away from the source in a spherical pattern.
The attenuation or sound drop-off rate is dependent on the conditions of the land between the noise source and receiver. To account for this ground-effect attenuation (absorption), two types of site conditions are commonly used in noise models: soft-site and hard-site conditions. Soft-site conditions account for the sound propagation loss over natural surfaces such as normal earth and ground vegetation. For point sources, a drop-off rate of 7.5 dBA per each doubling of the distance (dBA/DD) is typically observed over soft ground with landscaping, as compared with a 6 dBA/DD drop-off rate over hard ground such as asphalt, concrete, stone and very hard packed earth. For line sources, such as traffic noise on a roadway, a 4.5 dBA/DD is typically observed for soft-site conditions compared to the 3 dBA/DD drop-off rate for hard-site conditions.
Traffic Noise
The level of traffic noise depends on the three primary factors: (1) the volume of the traffic, (2) the speed of the traffic, and (3) the number of trucks in the flow of traffic. Generally, the loudness of traffic noise is increased by heavier traffic volumes, higher speeds, and greater number of trucks. Vehicle noise is a combination of the noise produced by the engine, exhaust, and tires. Because of the logarithmic nature of noise levels, a doubling of the traffic volume (assuming that the speed and truck mix do not change) results in a noise level increase of 3 dBA. Based on the Federal Highway Administration (FHWA) community noise assessment criteria, this change is “barely perceptible;” for reference, a doubling of perceived noise levels would require an increase of approximately 10 dBA. The truck mix on a given roadway also has an effect on community noise levels. As the number of heavy trucks increases and becomes a larger percentage of the vehicle mix, adjacent noise levels increase.
Stationary Noise
A stationary noise producer is any entity in a fixed location that emits noise. Examples of stationary noise sources include machinery, engines, energy production, and other mechanical or powered equipment and activities such as loading and unloading or public assembly that may occur at commercial, industrial, manufacturing, or institutional facilities. Furthermore, while noise generated by the use of motor vehicles over public roads is preempted from local regulation, although the use of these vehicles is considered a stationary noise source when operated on private property such as at a construction site, a truck terminal, or warehousing facility. The emitted noise from the producer can be mitigated to acceptable levels either at the source or on the adjacent property through the

The effects of stationary noise depend on factors such as characteristics of the equipment and operations, distance and pathway between the generator and receptor, and weather. Stationary noise sources may be regulated at the point of manufacture (e.g., equipment or engines), with limitations on the hours of operation, or with provision of intervening structures, barriers or topography.
Construction activities are a common source of stationary noise. Construction-period noise levels are higher than background ambient noise levels but eventually cease once construction is complete.
Construction is performed in discrete steps, each of which has its own mix of equipment and, consequently, its own noise characteristics. These various sequential phases would change the character of the noise generated on each construction site, and therefore, would change the noise levels as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction related noise ranges to be categorized by work phase. Table 3.11-1 shows typical noise levels of construction equipment as measured at a distance of 50 feet from the operating equipment.

Characteristics of Vibration
Groundborne vibrations consist of rapidly fluctuating motions within the ground that have an average motion of zero. The effects of groundborne vibrations typically only cause a nuisance to people, but in extreme cases, excessive groundborne vibration has the potential to cause structural damage to buildings. Although groundborne vibration can be felt outdoors, it is typically only an annoyance to people indoors where the associated effects of the shaking of a building can be notable. Groundborne noise is an effect of groundborne vibration and only exists indoors, since it is produced from noise radiated from the motion of the walls and floors of a room, and may also consist of the rattling of windows or dishes on shelves.
Several different methods are used to quantify vibration amplitude such as the maximum instantaneous peak in the vibrations velocity, which is known as the peak particle velocity (PPV) or the root mean square (rms) amplitude of the vibration velocity. Because of the typically small amplitudes of vibrations, vibration velocity is often expressed in decibels—denoted as LV—and is based on the reference quantity of 1 micro inch per second. To distinguish these vibration levels referenced in decibels from noise levels referenced in decibels, the unit is written as “VdB.” Although groundborne vibration can be felt outdoors, it is typically only an annoyance to people indoors where the associated effects of the shaking of a building can be notable. When assessing annoyance from groundborne vibration, vibration is typically expressed as rms velocity in units of decibels of 1 micro-inch per second, with the unit written in VdB. Typically, developed areas are continuously affected by vibration velocities of 50 VdB or lower. Human perception to vibration starts at levels as low as 67 VdB. Annoyance due to vibration in residential settings starts at approximately 70 VdB.
Off-site sources that may produce perceptible vibrations are usually caused by construction equipment, steel-wheeled trains, and traffic on rough roads, while smooth roads rarely produce perceptible groundborne noise or vibration. Construction activities, such as blasting, pile driving and operating heavy earthmoving equipment, are common sources of groundborne vibration.
Construction vibration impacts on building structures are generally assessed in terms of PPV. Typical vibration source levels from construction equipment are shown in Table 3.11-2.

The propagation of groundborne vibration is not as simple to model as airborne noise. This is because noise in the air travels through a relatively uniform medium, while groundborne vibrations travel through the earth, which may contain significant geological differences. Factors that influence groundborne vibration include:
Vibration source: Type of activity or equipment, such as impact or mobile, and depth of vibration source;
Vibration path: Soil type, rock layers, soil layering, depth to water table, and frost depth; and Vibration receiver: Foundation type, building construction, and acoustical absorption.

In addition, soil conditions are known to have a strong influence on the levels of groundborne vibration. Among the most important factors are the stiffness and internal damping of the soil and the depth to bedrock. Vibration propagation is more efficient in stiff clay soils than in loose sandy soils, and shallow rock seems to concentrate the vibration energy close to the surface, and can result in groundborne vibration problems at large distance from the source. Factors such as layering of the soil and depth to the water table can have significant effects on the propagation of groundborne vibration. Soft, loose, sandy soils tend to attenuate more vibration energy than hard, rocky materials.
Vibration propagation through groundwater is more efficient than through sandy soils. There are three main types of vibration propagation: surface, compression, and shear waves. Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water. Pwaves, or compression waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). P-waves are analogous to airborne sound waves. S-waves, or shear waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse, or side-to-side and perpendicular to the direction of propagation.
As vibration waves propagate from a source, the vibration energy decreases in a logarithmic nature and the vibration levels typically decrease by 6 VdB per doubling of the distance from the vibration source. As stated above, this drop-off rate can vary greatly depending on the soil type, but it has been shown to be effective enough for screening purposes, in order to identify potential vibration impacts that may need to be studied through actual field tests. The vibration level (PPV) at a distance from a point source can generally be calculated using the vibration reference equation:
PPV= PPVref * (25/D)^n (in/sec)
Where:
PPVref = reference measurement at 25 feet from vibration source D = distance from equipment to the receptor
n = vibration attenuation rate through ground
According to Chapter 12 of the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment manual (2006), an “n” value of 1.5 is recommended to calculate vibration propagation through typical soil conditions.
Existing Traffic Noise Levels
Existing traffic noise levels along selected roadway segments in the proposed project vicinity were modeled using the FHWA Traffic Noise Prediction Model (FHWA-RD-77-108). Site-specific information is entered, such as roadway traffic volumes, roadway active width, source-to-receiver distances, travel speed, noise source and receiver heights, and the percentages of automobiles, medium trucks, and heavy trucks that the traffic is made up of throughout the day, amongst other variables. The modeled average daily traffic (ADT) volumes were obtained by multiplying the PM

3.11.3 - Regulatory Framework
Federal
Noise Control Act
The adverse impact of noise was officially recognized by the federal government in the Noise Control Act of 1972, which serves three purposes:
Promulgating noise emission standardsfor interstate commerce Assisting State and local abatement efforts
Promoting noise education and research
The Federal Office of Noise Abatement and Control (ONAC) was initially tasked with implementing the Noise Control Act. However, the ONAC has since been eliminated, leaving the development of federal noise policies and programs to other federal agencies and interagency committees.
Among the agencies now regulating noise are the Occupational Safety and Health Administration (OSHA), which limits noise exposure of workers to 90 dB Leq or less for 8 continuous hours or 105 dB Leq or less for 1 continuous hour; the United States Department of Transportation (USDOT), which assumed a significant role in noise control through its various operating agencies; and the Federal Aviation Administration (FAA), which regulates noise of aircraft and airports. Surface transportation system noise is regulated by a host of agencies, including the FTA. Transit noise is regulated by the federal Urban Mass Transit Administration, while freeways that are part of the interstate highway system are regulated by the FHWA. Finally, the federal government actively advocates that local jurisdictions use their land use regulatory authority to arrange new development in such a way that “noise sensitive” uses are either prohibited from being sited adjacent to a highway, or alternatively, that developments are planned and constructed in such a manner that minimize potential noise impacts.
Since the federal government has preempted the setting of standards for noise levels that can be emitted by transportation sources, local jurisdictions are limited to regulating the noise generated by the transportation system through nuisance abatement ordinances and land use planning.
Federal Transit Administration
The proposed project is not subject to the regulation requirements of the FTA; however, the FTA’s vibration impact criteria are accepted industry-wide as the best vibration impact guidelines when a local governing agency does not have vibration standards of its own.
The FTA has established industry accepted standards for vibration impact criteria and impact assessment. These guidelines are published in its Transit Noise and Vibration Impact Assessment Manual, dated September 2018. The FTA guidelines include thresholds for construction vibration impacts for various structural categories as shown in Table 3.11-4.

State
The State of California has established regulations that help prevent adverse impacts to occupants of buildings located near noise sources. Referred to as the “State Noise Insulation Standard,” it requires buildings to meet performance standards through design and/or building materials that would offset any noise source in the vicinity of the receptor. State regulations include requirements for the construction of new hotels, motels, apartment houses, and dwellings other than detached singlefamily dwellings that are intended to limit the extent of noise transmitted into habitable spaces.
These requirements are found in the California Code of Regulations, Title 24 (known as the Building Standards Administrative Code), Part 2 (known as the California Building Code), Appendix Chapters 12 and 12A. For limiting noise transmitted between adjacent dwelling units, the noise insulation standards specify the extent to which walls, doors, and floor-ceiling assemblies must block or absorb sound. For limiting noise from exterior noise sources, the noise insulation standards set an interior standard of 45 dBA CNEL in any habitable room with all doors and windows closed. In addition, the standards require preparation of an acoustical analysis demonstrating the manner in which dwelling units have been designed to meet this interior standard, where such units are proposed in an area with exterior noise levels greater than 60 dBA CNEL.
Government Code Section 65302 mandates that the legislative body of each county and city in California adopt a noise element as part of its comprehensive general plan. The local noise element must recognize the land use compatibility guidelines published by the State Department of Health Services. These guidelines rank noise and land use compatibility in terms of normally acceptable, conditionally acceptable, normally unacceptable, and clearly unacceptable.
Local
The project site is located within the City of Patterson, in the County of Stanislaus. The City of Patterson addresses noise in the Health and Safety Element of its General Plan, adopted by the City of Patterson in 2010, and in the Noise Control Chapter of its Municipal Code, approved by the City in 2018.
City of Patterson 2010 General Plan
The City of Patterson adopted its General Plan in November of 2010. The objective of the Health and Safety Element’s noise section is to protect City residents from the harmful and undesirable effects of excessive noise. To assist with meeting this objective, the City’s Plan establishes land use noise

The City of Patterson establishes its land use noise compatibility guidelines for new developments in Figure HS-1 of its General Plan (shown in Table 3.11-5 below). Because the proposed project will include the development of various land use types, more than one land use category from this figure is applicable to the proposed project.
The City of Patterson rates land use compatibility in terms of normally acceptable, conditionally acceptable, normally unacceptable, and clearly unacceptable. If noise levels at a project site are within the conditionally acceptable range, new construction or development should be undertaken only after a detailed analysis of the noise reduction requirement is made and needed noise insulation features included in the design. Development of project sites with noise levels in the normally unacceptable range should generally be discouraged. However, if new construction or development does proceed under this scenario, a detailed analysis of the noise reduction requirements must be made with needed noise insulation features included in the design, and outdoor areas must be shielded.

Key:
Normally Acceptable: Specified land use is satisfactory based upon the assumption that any buildings involved are of normal conventional construction, without any special noise insulation requirements.
Conditionally Acceptable: New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements is made and needed noise insulation features included in the design.
Conventional construction, but with closed windows and fresh air supply systems or air conditioning will normally suffice. Outdoor environment will seem noisy.
Normally Unacceptable: New construction and development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made with needed noise insulation features included in the design. Outdoor areas must be shielded.
Clearly Unacceptable: New construction or development should generally not be undertaken.
The City establishes noise performance standards for noise-sensitive land uses affected by nontransportation noise sources in Table HS-1 of its General Plan (shown in Table 3.11-6 below).
According to this table and the General Plan’s policies, non-transportation noise sources shall not generate exterior noise in excess of the levels established in Table HS-1 at the property line of any planned or existing noise-sensitive land use.

3.11.4 - Methodology
Traffic Noise Modeling Methodology
The FHWA highway traffic noise prediction model (FHWA RD-77-108) was used to evaluate trafficrelated noise conditions in the vicinity of the proposed project site. Traffic data used in the model was obtained from the Advanced Mobility Group Traffic Impact Study (TIS) prepared for the proposed project. The resultant noise levels were weighed and summed over a 24-hour period in order to determine the CNEL values. The FHWA-RD-77-108 Model arrives at a predicted noise level through a series of adjustments to the Reference Energy Mean Emission Level. Adjustments are then made to the reference energy mean emission level to account for the roadway active width (i.e., the distance between the center of the outermost travel lanes on each side of the roadway); the total ADT; and the percentage of ADT that flows during the day, evening, and night; the travel speed; the vehicle mix on the roadway; a percentage of the volume of automobiles, medium trucks, and heavy trucks; the roadway grade; the angle of view of the observer exposed to the roadway; and the site conditions (“hard” or “soft”) as they relate to the absorption of the ground, pavement, or landscaping.
The level of traffic noise depends on the three primary factors: (1) the volume of the traffic, (2) the speed of the traffic, and (3) the number of trucks in the flow of traffic. Generally, the loudness of traffic noise is increased by heavier traffic volumes, higher speeds, and greater number of trucks.
Vehicle noise is a combination of the noise produced by the engine, exhaust, and tires. Because of the logarithmic nature of traffic noise levels, a doubling of the traffic volume (assuming that the speed and truck mix do not change) results in a noise level increase of 3 dBA. Based on the FHWA community noise assessment criteria, this change is “barely perceptible.” For reference, a doubling of perceived noise levels would require an increase of approximately 10 dBA. The truck mix on a given roadway also has an effect on community noise levels. As the number of heavy trucks increases and becomes a larger percentage of the vehicle mix, adjacent noise levels increase.
The model analyzed the noise impacts from the nearby roadways onto the proposed project vicinity, which consists of the area that has the potential of being impacted from the on-site noise sources as well as the proposed project-generated traffic on the nearby roadways. The roadways were analyzed based on a single-lane-equivalent noise source combining both directions of travel. A single-laneequivalent noise source exists when the vehicular traffic from all lanes is combined into a theoretical single lane that has a width equal to the distance between the two outside lanes of a roadway, which provides almost identical results to analyzing each lane separately where elevation changes are minimal.

3.11.5 - Thresholds of Significance
According to Appendix G, Environmental Checklist, of the CEQA Guidelines, noise impacts resulting from the implementation of the proposed project would be considered significant if the proposed project would result in:
a) A significant environmental impact due to a conflict with any applicable land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? b) 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?
c) Generation of excessive groundborne vibration or groundborne noise levels? d) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
It should be noted that the significance criteria question a), above, is from the Land Use and Planning section of the CEQA Guidelines Appendix G checklist questions. However, this question addresses impacts related to conflicts with land use plans, which would include project-related conflicts to the noise land use compatibility standards of the Noise Element of the General Plan.
Therefore, these impacts are addressed here.
3.11.6 - Project Impacts and Mitigation Measures
This section discusses potential impacts associated with the development of the proposed project and provides mitigation measures where appropriate.
Noise Levels That Would Conflict with Any Land Use Plan, Policy, or Regulation Impact NOI-1: Buildout of the Master Plans may cause a significant environmental impact due to a conflict with any applicable land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect.
Impact Analysis
Zacharias and Baldwin Master Plans
A significant impact would occur if implementation of the proposed project would expose the proposed noise sensitive receptors to noise levels in excess of the City’s exterior noise level standards for new land use development. For example, the City considers environments with ambient noise levels of up to 60 dBA CNEL to be “normally acceptable” for new residential land use development, and environments with noise levels above 60 dBA and up to 70 dBA CNEL are considered “conditionally acceptable” for new residential land use development.

Traffic modeling was performed using the data obtained from the proposed project-specific traffic impact study conducted by Advanced Mobility Group. This traffic impact study provides data for existing (2019) and cumulative (2040) conditions. The resultant noise levels were weighed and summed over a 24-hour period to determine the CNEL values. The traffic noise modeling input and output files—including the 60 dBA, 65 dBA, and 70 dBA CNEL noise contour distances—are included in Appendix H. Table 3.11-8 shows a summary of the traffic noise levels for existing (2019), existing plus approved projects, existing plus approved projects plus proposed project, 2040 cumulative no project, 2040 cumulative plus project, and the 2040 cumulative plus project (with new Zacharias Avenue/Interstate 5 [I-5] interchange) conditions, as measured at 50 feet from the centerline of the outermost travel lane.

The highest traffic noise levels that would be experienced at the proposed project would occur on Zacharias Road between Baldwin Road and Highway 33 under Existing Plus Approved Projects Plus Proposed Project conditions. These traffic noise levels would range up to approximately 68.8 dBA CNEL as measured at 50 feet from the centerline of the nearest travel lane. Based on the proposed plan development areas, the nearest proposed residential façades could be located approximately 90 feet from the centerline of the roadway. At this distance, traffic noise levels would attenuate to below 64 dBA CNEL. These traffic noise levels are between 60 dBA and 70 dBA CNEL which the City considers to be “conditionally acceptable” for new residential land use developments.
Based on the United States Environmental Protection Agency (EPA) Protective Noise Levels,1a combination of walls, doors, and windows provided in accordance with State building code requirements for the proposed residential development would result in a 25 dBA in exterior-tointerior noise reduction with windows closed and a 15 dBA or more with windows open. With windows open, interior noise levels of the nearest proposed units to Highway 33 would not meet the interior noise standard of 45 dBA Leq (i.e., 64 dBA–15 dBA = 49 dBA). This impact is potentially 1 United States Environmental Protection Agency (EPA) 550/9-79-100, November 1978.

Therefore, Mitigation Measure (MM) NOI-1 is included, which requires that the proposed project shall include a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods. The inclusion of the proposed air conditioning system would allow windows to remain closed and would provide attenuation of up to 25 dBA, which would be sufficient to reduce traffic noise levels to meet the interior noise level standard of 45 dBA Leq (i.e., 64 dBA–25 dBA = 39 dBA). This mitigation measure would ensure that potentially impacted interior residential units would meet the interior noise level requirement of 45 dBA Leq. Therefore, with implementation of MM NOI-1, future projected traffic noise impacts would be reduced to less than significant.
Thus, traffic noise levels adjacent to the proposed project site would not exceed noise levels that the City of Patterson considers acceptable for new residential land uses. As such, traffic noise would result in a less than significant impact for the proposed residential development.
Therefore, the impact related to noise land use compatibility standards consistency would be less than significant.
Level of Significance Before Mitigation
Potentially significant impact.
Mitigation Measures
MM NOI-1 Prior to issuance of residential building permits for the Zacharias Master Plan, the applicant shall submit building plans to the City of Patterson for review and approval that demonstrate that each dwelling unit includes a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods for all residential units within 100 feet of Zacharias Road, Baldwin Road, or State Route 33.
Level of Significance After Mitigation
Less than significant impact.
Substantial Noise Increase in Excess of Standards
Impact NOI-2: Buildout of the Master Plans may 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.
Impact Analysis
This impact assesses construction and operational noise.
Baldwin and Zacharias Master Plans
Construction
A significant impact would occur if construction activities would result in a substantial increase in ambient noise levels outside of the City’s permissible hours for construction that would result in annoyance or sleep disturbance of nearby sensitive receptors.

Two types of short-term noise impacts would occur during site preparation and project construction.
The first type would result from the increase in traffic flow on local streets, associated with the transport of workers, equipment, and materials to and from the proposed project site. The transport of workers and construction equipment and materials to the proposed project site would incrementally increase noise levels on access roads leading to the site. Because workers and construction equipment would use existing routes, noise from passing trucks would be similar to existing vehicle-generated noise on these local roadways. Typically, a doubling of the average daily trip (ADT) hourly volumes on a roadway segment is required in order to result in an increase of 3 dBA in traffic noise levels; which, as discussed in the characteristics of noise discussion above, is the lowest change that can be perceptible to the human ear in outdoor environments. Project-related construction trips would not be expected to double the hourly traffic volumes along any roadway segment in the proposed project vicinity. For these reasons, short-term intermittent noise from trucks would be minor when averaged over a longer time-period. Therefore, short-term construction-related noise impacts associated with worker commute and equipment transport to the proposed project site would not exceed applicable significance thresholds and would be less than significant.
The second type of short-term noise impact is related to noise generated during site-preparation, grading, and construction activities. Construction is performed in discrete steps, each of which has its own mix of equipment, and consequently, its own noise characteristics. These various sequential phases would change the character of the noise generated on-site. Thus, the noise levels vary as construction progresses through each phase. Despite the variety in the types and sizes of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction noise ranges to be categorized by work phase. Table 3.11-1 shows typical noise levels of construction equipment as measured at a distance of 50 feet from the operating equipment.
The site preparation phase, which includes excavation and grading activities, generate the highest noise levels because the noisiest construction equipment is earthmoving equipment. Earthmoving equipment includes excavating machinery and compacting equipment, such as bulldozers, draglines, backhoes, front loaders, roller compactors, scrapers, and graders. Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 or 4 minutes at lower power settings.
The proposed project is expected to require the use of scrapers, bulldozers, water trucks, haul trucks, and pickup trucks. Based on the information provided in Table 3.11-1, the maximum noise level generated by each scraper is assumed to be 85 dBA Lmax at 50 feet from this equipment. Each bulldozer would generate 85 dBA Lmax at 50 feet. The maximum noise level generated by graders is approximately 85 dBA Lmax at 50 feet. Each doubling of sound sources with equal strength increases the noise level by 3 dBA. Assuming that each piece of construction equipment operates at some distance from the other equipment, a reasonable worst-case combined noise level during this phase of construction would be 90 dBA Lmax at a distance of 50 feet from the acoustic center of a construction area. This would result in

The acoustical center reference is used because construction equipment must operate at some distance from one another on a project site, and the combined noise level as measured at a point equidistant from the sources (acoustic center) would be the worst-case maximum noise level.
The closest noise-sensitive receptors to the proposed Zacharias Master Plan development areas are single-family residences located along the proposed project site’s southern boundary. The closest residence could be located as close as 115 feet from the acoustic center of construction activity where multiple pieces of heavy construction equipment would potentially operate within the plan area. At this distance, worst-case construction noise levels could range up to approximately 83 dBA Lmax, intermittently, and could have an hourly average of up to 79 dBA Leq, at the façade of the nearest single-family residential home. These noise levels would be intermittent and would be reduced at a rate of 6 dB per doubling of distance as equipment moves over the proposed project site further from adjacent sensitive receptors.
The closest noise-sensitive receptors to the proposed Baldwin Master Plan development areas are single-family residences located northeast of the proposed project site’s northern boundary. The closest residence could be located as close as 350 feet from the acoustic center of construction activity where multiple pieces of heavy construction equipment would potentially operate within the plan area. At this distance, worst-case construction noise levels could range up to approximately 83 dBA Lmax, intermittently, and could have an hourly average of up to 69 dBA Leq, at the façade of the nearest single-family residential home. These noise levels would be intermittent and would be reduced at a rate of 6 dB per doubling of distance as equipment moves over the proposed project site further from adjacent sensitive receptors.
Compliance with City’s permissible construction hours would reduce the effects of noise produced by construction activities on longer-term (hourly or daily) ambient noise levels and would reduce potential impacts that could result in annoyance or sleep disturbances at nearby sensitive receptors.
The City of Patterson limits noise-producing construction activities located within five hundred feet of a residential zone to the hours between 7:00 a.m. and 10:00 p.m., daily. Restricting construction activities to these time-periods and implementing the best management noise reduction techniques and practices outlined in MM NOI-2, would ensure that construction noise levels would not result in a substantial temporary increase in ambient noise levels that could result in annoyance or sleep disturbance of nearby sensitive receptors. Therefore, potential short-term construction noise impacts on receptors in project vicinity would be reduced to a less than significant level.
Operation
The proposed project will result in an increase in traffic on local roadway segments in the proposed project vicinity. In addition, implementation of the proposed project would introduce new stationary noise sources to the ambient noise environment in the proposed project vicinity, including parking lot activities and new mechanical ventilation equipment. The potential for a substantial increase in ambient noise levels resulting from these noise sources is analyzed below.

The City of Patterson also establishes noise level performance standards for new projects affected by or including transportation sources. The maximum noise threshold for outdoor activity areas is 60 CNEL, and the maximum noise threshold for interior spaces is 45 dBA Leq.
The City of Patterson does not define “substantial increase;” therefore, for purpose of this analysis, a substantial increase is based on the following criteria. As noted in the characteristics of noise discussion, audible increases in noise levels generally refer to a change of 3 dBA or more, as this level has been found to be barely perceptible to the human ear in outdoor environments. A change of 5 dBA is considered the minimum readily perceptible change to the human ear in outdoor environments. Therefore, for purposes of this analysis, a significant impact would occur if the proposed project would cause the CNEL to increase by 5 dBA or greater and thereby cause the CNEL in the proposed project vicinity to exceed conditionally acceptable levels for receiving land uses.
The FHWA highway traffic noise prediction model (FHWA RD-77-108) was used to evaluate existing and future project-related traffic noise conditions along modeled roadway segments in the vicinity of the proposed project site. The projected future traffic noise levels on roadways adjacent to the site were analyzed to determine compliance with the City’s noise and land use compatibility standards. Traffic modeling was performed using the data obtained from the proposed project-specific traffic impact study conducted by Advanced Mobility Group. This traffic impact study provides data for Existing (2019), Existing Plus Approved Projects (2019), Cumulative (2040), and Cumulative (with new Zacharias Avenue/I-5 Interchange) conditions. The resultant noise levels were weighed and summed over a 24- hour period to determine the CNEL values. The traffic noise modeling input and output files—including the 60 dBA, 65 dBA, and 70 dBA CNEL noise contour distances—are included in Appendix H. As shown previously, Table 3.11-8 shows a summary of the traffic noise levels for Existing (2019), Existing Plus Approved Projects, Existing Plus Approved Projects Plus Proposed Project, 2040 Cumulative No Project, 2040 Cumulative Plus Project, the 2040 Cumulative Plus Project (with new Zacharias Avenue/I-5 interchange) conditions, as measured at 50 feet from the centerline of the outermost travel lane.
As shown in Table 3.11-8, the highest traffic noise level increase with implementation of the proposed project would occur along Zacharias Road between Rogers Road and Baldwin Road under 2040 cumulative plus project (with new Zacharias Avenue/I-5 interchange) conditions. Along this roadway segment, the proposed project would result in traffic noise levels ranging up to approximately 63.4 dBA CNEL as measured at 50 feet from the centerline of the nearest travel lane, representing an increase of 9 dBA over 2040 cumulative no project conditions for this roadway segment. However, the resulting traffic noise levels of 63.4 dBA CNEL would still be within the City’s “conditionally acceptable” range for new residential land use developments. Furthermore, none of the modeled roadway segments would experience traffic noise levels that are in excess of the City’s conditionally acceptable land use compatibility standard for residential land uses of 70 dBA CNEL.
Therefore, implementation of the Master Plans would not result in a substantial permanent increase in traffic noise levels that would cause the CNEL to increase by 5 dBA or greater and thereby cause the CNEL in the proposed project vicinity to exceed conditionally acceptable levels for receiving land uses. Thus, traffic noise increase impacts associated with implementation of the Master Plans would be less than significant.

A significant impact would occur if project stationary noise sources would result in a substantial permanent increase in ambient noise levels that would exceed the following thresholds at the property line of any noise-sensitive land use in the proposed project vicinity:
50 dBA Leq or 70 dBA Lmax between the hours of 7:00 a.m. and 10:00 p.m.; or 45 dBA Leq or 65 dBA Lmax between the hours of 10:00 p.m. and 7:00 a.m.
The proposed project would include new stationary noise sources such as parking lot activities and mechanical ventilation system equipment. These would be potential point sources of noise that could affect receptors in the proposed project vicinity.
As described in the characteristics of noise section, as noise spreads from a source, it loses energy so that the farther away the noise receiver is from the noise source, the lower the perceived noise level would be. Geometric spreading causes sound levels to attenuate or be reduced, resulting in a 6-dB reduction in the noise level for each doubling of distance from a single point source of noise to the noise-sensitive receptor of concern. Additionally, if sensitive receptors are shielded from noise by buildings, sound barriers, or other structures, this would provide additional attenuation. The amount of attenuation provided by shielding is a function of the height of the intervening structure and its ability to block the line of site between a noise source and receptor. Therefore, the significance of any potential impact would vary with the distance between proposed stationary noise sources and sensitive receptors and the inclusion of any intervening structures or barriers.
Parking Lot Activities
Proposed medium- and high-density residential land uses would require parking areas for staff, visitors, and persons residing within the plan area. Parking lot activities include vehicles cruising at slow speeds, doors shutting, or cars starting, would generate noise levels of approximately 60 dBA to 70 dBA Lmax at 50 feet. A conversation between two persons at a distance of 3 to 5 feet apart would generate a noise level of 60 dBA Leq at 5 feet, or approximately 40 dBA Leq as measured at 50 feet.
At the time that this analysis was prepared, the location of the proposed parking areas was not identified on the area plan. The closest noise-sensitive receptors to potential areas where parking lots could be developed are single-family residences located within 50-feet of the plan area’s southern boundary. At a distance of 100 feet, parking lot activity intermittent noise levels would attenuate to below the City’s nighttime noise performance standards of 45 dBA Leq or 64 dBA Lmax.
Therefore, proposed parking areas should be located a minimum of 100 feet from existing residential land uses or should provide shielding to block the line of sight to nearby noise sensitive land uses to meet the City’s nighttime noise performance standards. Therefore, with implementation of MM NOI2b parking lot activity associated with the Zacharias Master Plan development would not generate a substantial temporary or permanent increase in excess of the City’s nighttime noise performance standards as measured at the nearest sensitive receptors, and the impact would be reduced to less than significant.

Zacharias Master Plan Area
At the time that this analysis was prepared, the location of potential mechanical ventilation systems was not identified on the area plan. The closest noise-sensitive receptors to potential areas where new mechanical equipment could be located are single-family residences located within 50-feet of the plan area’s southern boundary. At a distance of 55 feet, typical residential mechanical ventilation system operation noise levels would attenuate to below the City’s nighttime noise performance standards of 45 dBA Leq or 64 dBA Lmax. Therefore, proposed mechanical ventilation systems should be located a minimum of 55 feet from existing sensitive receptors or should provide shielding to block the line of sight to nearby noise sensitive land uses to meet the City’s nighttime noise performance standards. Therefore, with implementation of MM NOI-2c mechanical ventilation equipment operations associated with the Zacharias Master Plan development would not generate a substantial temporary or permanent increase in excess of the City’s noise standards as measured at the nearest sensitive receptors, and the impact would be reduced to less than significant Baldwin Master Plan Area
At the time that this analysis was prepared, the location of potential mechanical ventilation systems was not identified on the area plan. The closest existing noise-sensitive receptors are single-family residences, located northeast approximately 300 feet from the Baldwin Master Plan nearest potential areas where new mechanical equipment could be located. At this distance, residential mechanical ventilation system noise levels would attenuate to below 30 dBA Leq at the property line of this nearest sensitive receptor. As a result, noise levels from residential mechanical ventilation system operations would not exceed the City’s nighttime noise performance thresholds of 45 Leq or 65 dBA Lmax at the property line of the nearest existing noise-sensitive land use. Therefore, residential mechanical ventilation system operations associate with the Baldwin Master Plan development would not generate a substantial temporary or permanent increase in excess of the City’s nighttime noise performance standards as measured at the nearest sensitive receptors, and the impact would be reduced to less than significant without mitigation.

If shielding is needed, shielding shall have a minimum height sufficient to completely block line-of-sight between the on-site noise source and the nearest residential dwelling to meet the City’s noise standards.

This section analyzes both construction and operational groundborne vibration impacts. The City of Patterson has not established a standard for excessive groundborne vibration levels resulting from construction activities. Therefore, for purposes of this analysis, the FTA vibration impact criteria are utilized. The FTA has established industry accepted standards for vibration impact assessment in its Transit Noise and Vibration Impact Assessment Manual dated September 2018. These guidelines are summarized in Table 3.11-4.
Construction
Construction activity can result in varying degrees of ground vibration, depending on the equipment used on the site. Operation of construction equipment causes ground vibrations that spread through the ground and diminish in strength with distance. Buildings in the vicinity of a construction site respond to these vibrations with varying results ranging from no perceptible effects at the low levels, to slight damage at the highest levels.
Of the variety of equipment used during construction, the small vibratory rollers that would be used in the site preparation phase of construction would produce the greatest groundborne vibration levels. Small vibratory rollers produce groundborne vibration levels ranging up to 0.101 inch per second (in/sec) PPV at 25 feet from the operating equipment.
The closest off-site structures to development that could occur in the Zacharias Master Plan area are single-family residences located along the plan area’s southern boundary. Based on the proposed land use development plan, the façade of the nearest structure could be located as close as 50 feet from the construction footprint where heavy equipment would operate within the Master Plan area.
At this distance, operation of small vibratory rollers could result in groundborne vibration levels of up to 0.036 PPV at this nearest receptor. This is below the industry standard vibration damage criteria of 0.2 PPV for the most sensitive type of structure: buildings extremely susceptible to vibration damage. Therefore, groundborne vibration levels associated with construction activities at the proposed project site would have a less than significant impact on off-site receptors in the proposed project vicinity.
Operation
The Baldwin Master Plan is residential only and, thus, would not have the potential to introduce new substantial sources of vibration.
The Zacharias Master Plan includes light industrial uses that would be served by trucks. The light industrial uses would be served by Rogers Road, which is currently used by heavy trucks serving Vista Del Lago, the Keystone Pacific Business Park, and the Arambel Business Park. Despite the significant truck volumes on Rogers Road, nearby buildings do not exhibit vibration damage, indicating that truck vibration is de minimis. As such, it would be expected that the Zacharias Master Plan light industrial uses would not result in substantial sources of vibration.
Additionally, the only existing significant permanent sources of groundborne vibration in the vicinity of the area to which the proposed Master Plan area would be exposed is the railroad located adjacent to State Route 33. However, project development would occur beyond 100 feet from the

3.12.3 - Regulatory Setting
State
California Housing Element Law
State law requires each city and county to adopt a general plan for future growth. This plan must include a housing element that identifies housing needs for all economic segments and provides opportunities for housing development to meet that need. At the state level, the Department of Housing and Community Development (HCD) estimates the relative share of California’s projected population growth that would occur in each county in the State, based on DOF population projections and historic growth trends. Where there is a regional council of governments, such as StanCog, HCD provides the regional housing need to the council. The council then assigns a share of the regional housing need to each of its cities and counties. The process of assigning shares provides cities and counties the opportunity to comment on the proposed allocations. HCD oversees the process to ensure that the council of governments distributes its share of the State’s projected housing need.
Each city and county must update its general plan housing element on a regular basis (approximately every 5 years). Among other things, the housing element must incorporate policies and identify potential sites that would accommodate a city’s share of the regional housing need. Before adopting an update to its housing element, a city or county must submit the draft to HCD for review. HCD will

The councils of governments are required to assign regional housing shares to the cities and counties within their region on a similar 5-year schedule. At the beginning of each cycle, HCD provides population projections to the councils of governments, which then allocate shares to their cities and counties. The shares of the regional need are allocated before the end of the cycle so that the cities and counties can amend their housing elements by the deadline.

General Plan
The General Plan establishes the following goals and policies related to population, housing, and employment that are applicable to the proposed project:
Goal ED-2: To prepare and acquire an educated and skilled workforce to match the needs of the local and regional economies.
Goal ED-2: To promote a diverse and balanced mix of employment and housing opportunities.
Policy ED-3.1: Jobs-to-housing ratio. The City shall maintain an adequate retail, business, and industrial land supply to meet a jobs-to-housing ratio of at least 1.0.
Goal H-1: It is the Goal of the City of Patterson to assist in increasing the availability of permanent housing for all community residents.
Policy H-1-6-1: Continue to cooperate with large employers, and major commercial and industrial developers to identify and implement programs to balance employment growth, as outlined in the Land Use Goals of the 2004 Update of the Patterson General Plan, with the ability to provide housing opportunities affordable to the incomes of the newly created job opportunities and consider the effects of new employment, particularly in relation to housing demands, when new commercial or industrial development is proposed.
Goal LU-1.6: Small town character. The City shall seek to preserve Patterson’s traditional small-town qualities and agricultural heritage, while increasing its residential and employment base.
Goal LU-1.9: Managing the relationship between jobs and housing. The City shall monitor residential and non-residential development and encourage adjustments as necessary in land use designations and the rate of project approvals to promote a reasonable citywide balance between new employment-generating development and housing development and to minimize traffic impacts.
3.12.4 - Methodology
Impacts on population, housing, and employment were assessed by reviewing existing and anticipated population, housing, and employment projections provided the California Department of Finance, the California Employment Development Department and the City of Patterson General Plan.

3.12.5 - Thresholds of Significance
According to the CEQA Guidelines’ Appendix G Environmental Checklist, to determine whether impacts to population and housing are significant environmental effects, the following questions are analyzed and evaluated. Would the project:
a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
3.12.6 - Project Impacts and Mitigation Measures
This section discusses potential impacts associated with the proposed project and provides mitigation measures where necessary.
Growth Inducement
Impact POP-1: Buildout of the Master Plans would not induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure).
Impact Analysis
There are two types of direct growth inducement: construction of new dwelling units and the creation of new job opportunities. Indirect growth inducement occurs when “barriers to growth” are removed, such as the extension of essential utilities to unserved areas.
At buildout, the two Master Plans would support an estimated 19,988 new residents and 8,670 employees on existing agricultural land that would be annexed into the City of Patterson.
Additionally, the Master Plans contemplate a network of urban infrastructure including roads and utilities. Each Master Plan is discussed separately.
Baldwin Master Plan
The Baldwin Master Plan would support a population of 1,199 at buildout. Because of its small size and single use, the Baldwin Master Plan would buildout over a period of 5 years. When compared to the historical population growth totals shown in Table 3.12-2, the Baldwin Master Plan would be in line with past growth periods.
The City of Patterson General Plan contemplates a buildout population of 66,673 persons. Given that the City’s existing population (23,764) is roughly half of the projected buildout population, the Baldwin Master Plan would be within the General Plan’s growth projections.
The Baldwin Master Plan would include the extension of roads, storm drainage, water, sewer, electricity, and natural gas services to the Master Plan area. These connections would occur at Baldwin Road or Sperry Avenue. No off-site infrastructure connections would occur through areas

Zacharias Master Plan
The Zacharias Master Plan would support a population of 18,789 and 8,670 employees at buildout.
Because of its size and scale, the Zacharias Master Plan would buildout over a period of 20 years.
When broken down into 5-year increments, this averages to 4,695 additional persons and 2,168 additional employees every 5 years. When compared to the historical population growth totals shown in Table 3.12-2, the Zacharias Master Plan would be in line with past growth periods.
The City of Patterson General Plan contemplates a buildout population of 66,673 persons and 32,196 employees. Given that the City’s existing population (23,764) is roughly half of the projected buildout population and existing employment (9,500) is roughly a third of the projected buildout employment, the Zacharias Master Plan would be within the General Plan’s growth projections.
The Zacharias Master Plan would include the extension of roads, storm drainage, water, sewer, electricity, and natural gas services to the Master Plan area. These connections would occur at Keystone Pacific Parkway, Baldwin Road, and Ward Avenue. No off-site infrastructure connections would occur through areas unserved by urban infrastructure. As such, the proposed Master Plan would not result in growth inducement.
Combined Master Plans
The Baldwin Master Plan and Zacharias Master Plan would add a combined 19,988 persons and 8,670 employees at buildout. The City of Patterson General Plan contemplates a buildout population of 66,673 persons and 32,196 employees. Given that the City’s existing population (23,764) is roughly half of the projected buildout population and existing employment (9,500) is roughly a third of the projected buildout employment, both Master Plans would be within the General Plan’s growth projections. As such, the proposed Master Plan would not result in growth inducement.
Level of Significance Before Mitigation
Less than significant impact.
Mitigation Measures
No mitigation is necessary.
Level of Significance After Mitigation
Less than significant impact.
Housing Displacement
Impact POP-2: The project would not displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere.
Impact Analysis
This impact assesses whether the proposed Master Plans would displace housing or persons.

Buildout of the Master Plan would be limited to the Master Plan boundaries. There is an existing cluster of structures that include at least one residence. The removal of these structures would not represent the loss of a substantial amount of housing given that 305 new dwelling units would be developed in their place. Impacts would be less than significant.
Zacharias Master Plan
The 1,160 acres of the Master Plan area that excludes the Ranchette Triangle contains agricultural land. There are two clusters of residential and agricultural structures within this area that would ultimately be removed as the Master Plan builds out. The removal of these structures would not represent the loss of a substantial amount of housing given that 4,350 new dwelling units would be developed in their place.
The 137-acre Ranchette Triangle contains more than 30 separate parcels. The Master Plan allows property owners to continue existing land use activities after annexation. Thus, any change in land use activities (including development to a higher and better use) would be the prerogative of the property owner. Regardless, there would be a net increase in the number of dwelling units, which would offset the loss of the existing dwelling units.
Impacts would be less than significant.

Mitigation Measures
No mitigation is necessary.

3.13.6 - Project Impacts and Mitigation Measures
Fire Protection
Impact PSR-1: Buildout of the Master Plans may result in a need for new or expanded fire protection facilities.
Impact Analysis
This impact assesses whether the proposed project would result in a need for new or expanded fire protection and emergency medical service facilities.
Baldwin Master Plan
Fire Station No. 2 is located 1.7 miles from the Baldwin Master Plan area. Using an average travel speed of 35 miles per hour, a fire engine traveling from Station No. 2 to the Master Plan area would take 2 minutes, 55 seconds. This is considered an acceptable response time and, thus, the Master Plan would not require the construction of new fire station in order to achieve maintain adequate response times.
The City of Patterson General Plan Policy PS-6.4 sets forth a staffing ratio of 1.0 firefighter per 1,000 residents. Buildout of the Baldwin Master Plan would add 1,199 residents to the City of Patterson and, thus, create a need for 1-2 additional firefighters. Staffing is a policy decision at the discretion of the Patterson City Council and outside the scope of the environmental reviews process because it does not have physical impacts on the environment.
Nonetheless, buildout of the Master Plan would create a citywide need for at least one additional fire station or expansion of one of the two existing fire stations. Mitigation Measure (MM) PSR-1 requires the Master Plan applicant to pay development fees in accordance with the latest adopted

Zacharias Master Plan
Fire Station No. 2 is located 2.5 miles from the intersection of Rogers Road/Zacharias Road, the furthest portion of the Zacharias Master Plan area from the fire station. Using an average travel speed of 35 miles per hour, a fire engine traveling from Station No. 2 to the Master Plan area would take 4 minutes, 17 seconds. This is considered an acceptable response time and, thus, the Master Plan would not require the construction of new fire station in order to achieve maintain adequate response times.
The City of Patterson General Plan Policy PS-6.4 sets forth a staffing ratio of 1.0 firefighter per 1,000 residents. Buildout of the Zacharias Master Plan would add 18,789 residents to the City of Patterson and, thus, create a need for 18-19 additional firefighters. Staffing is a policy decision at the discretion of the Patterson City Council and outside the scope of the environmental reviews process because it does not have physical impacts on the environment.
Nonetheless, buildout of the Master Plan would create a citywide need for at least one additional fire station or expansion of one of the two existing fire stations.

Schools
Impact PSR-3: Buildout of the Master Plans would not result in a need for new or expanded schools beyond those contemplated by the project..
Impact Analysis
This impact assesses whether the proposed project would require a need for new or expanded school facilities.
Baldwin Master Plan
Buildout of the Baldwin Master Plan would add 305 dwelling units and 1,199 residents to the City of Patterson. Using a student generation rate of 0.624 student/dwelling unit, the Baldwin Master Plan would add 191 students to PUSD. This was calculating using a conservative student generation rate of 0.624 student per dwelling unit as set forth in the 2018 School Facility Needs Analysis for the Patterson Join Unified School District.
The Baldwin Master Plan applicant would be required to pay development fees to the School District to fund capital improvements to school facilities. Pursuant to Government Code Section 65995, payment of development fees is “full and complete mitigation” for impacts on schools. Impacts would be less than significant.
Zacharias Master Plan
Buildout of the Zacharias Master Plan would add 4,781 dwelling units and 18,789 residents to the City of Patterson. Using a student generation rate of 0.624 student/dwelling unit, the Zacharias Master Plan would add 2,984 students to PUSD.
The Zacharias Master Plan contemplates an approximately 14-acre elementary school site east of Baldwin Road and a 16-acre middle school site west of Baldwin Road. Those schools are part of the Master Plan and are evaluated in this EIR. Following adoption of the Zacharias Master Plan entitlements, PUSD will have a defined period of time to exercise its option to acquire and develop the schools. The Zacharias Master Plan applicants that would dedicate school sites would be credited the value of the land against is school development fee obligation.
For the Zacharias Master Plan applicants that do not dedicate school sites, they would be required to pay development fees to the School District to fund capital improvements to school facilities.

This section describes the existing transportation setting and potential effects from project implementation on the site and its surrounding area. Descriptions and analysis in this section are based on the Traffic Impact Study prepared by Advanced Mobility Group (AMG). The complete study is provided in Appendix H.
3.14.2 - Environmental Setting
Roadway Network
The following section describes the existing transportation conditions in the vicinity of the study area, including descriptions of the existing street system and intersection operating conditions.
Interstate 5
Interstate 5 (I-5) is a four-lane freeway near Patterson. Per the 2016 traffic counts obtained from the Caltrans website, I-5 carries between 40,000 to 48,000 vehicles per day (vpd) in the vicinity of Sperry Avenue. For regional travel, residents rely primarily on I-5, a major north-south freeway to the west of the city limits. I-5 connects to I-580, approximately 15 miles to the north of Patterson. I-5 and I580 provide access to regional employment centers in Pleasanton, San Ramon, and the rest of the San Francisco Bay Area.
The interchange of I-5/Sperry Avenue is configured as a tight diamond (Type L1) with a narrow underpass road and a steep drop in grade next to the northbound on-ramp. All ramps have one lane in each direction.
State Route 33
State Route 33 (SR-33) is located approximately three miles to the east of I-5. SR-33 provides northsouth access to Westley to the north and the City of Newman to the south. Its ADT is approximately 6,000 vpd. It is the main north-south roadway in Patterson.
Sperry Avenue is a two- to four-lane major arterial roadway that serves as the major route of travel between I-5 to the west and the City of Patterson to the east. Sperry Avenue terminates at SR-33, three miles east of I-5. Near the freeway, its ADT ranges between 12,000 to 14,000 vpd. A recent count to the east of Rogers Road showed the ADT to be approximately 15,040 vpd.
Rogers Road
Rogers Road is a two to three lane north-south collector street located generally to the east of I-5.
The road starts from Sperry Avenue to the south and ends at SR-33 to the north. Its ADT is approximately 2,400 vpd.
East Las Palmas Avenue
East Las Palmas Avenue is a three-lane major east west arterial including a center two-way left-turn lane between SR-33 and Sycamore Avenue, where it narrows to a two-lane road.

Main Street near the San Joaquin River.
Zacharias Road
Zacharias Road is currently a primarily two-lane rural road that extends from SR-33 in the east to slightly past I-5 freeway underpass. West of Rogers Road it is generally unpaved two-lane farm road.
Its ADT is approximately 320 vpd.
Baldwin Road
Baldwin Road is a two-lane north-south collector roadway that connects State Route 33 in the north and a residential neighborhood to the south of Sperry Avenue. This roadway provides access to the industrial and retail establishments in the northwest part of Patterson as well as to residential neighborhoods. Its ADT is approximately 4,910 vpd.

Level of Service
Level of Service is a qualitative index of the performance of an element of the transportation system.
Level of Service (LOS) is a rating scale running from A to F, with A indicating no congestion of any kind, and F indicating intolerable congestion and delays.
The 2010 Highway Capacity Manual (HCM) is the standard reference published by the Transportation Research Board and contains the specific criteria and methods to be used in assessing LOS. There are several software packages that have been developed to implement HCM. In this study the Synchro software was used to calculate the LOS at the study intersections.
Signalized Intersections
The relationship between average control delay, driver’s perception of traffic, and LOS for signalized intersections is summarized in Table 3.14-1.
Table 3.14-1: Signalized Intersection LOS Criteria
LOS Driver’s Perception and Traffic Operation Description Delay in Seconds A Little or no delays < 10
B Short traffic delays > 10–15
C Average traffic delays > 15–25
D Long traffic delays > 25–35
E Very long traffic delays > 35–50
F Extreme traffic delays with intersection capacity exceeded > 50 Source: AMG 2020.
Unsignalized Intersections
The method of unsignalized intersection capacity analysis used in this study is from Chapter 19, “Two-Way Stop-Controlled Intersections” of the Highway Capacity Manual. This method applies to two-way STOP sign or YIELD sign-controlled intersections (or one-way STOP sign or YIELD sign controlled intersections at three-way intersections). At such intersections, drivers on the minor street are forced to use judgment when selecting gaps in the major flow through which to execute crossings or turning maneuvers. Thus, the capacity of the controlled legs of an intersection is based on three factors:
1. The distribution of gaps in the major street traffic stream.
2. Driver judgment in selecting gaps through which to execute their desired maneuvers.
3. Follow-up time required to move into the front-of-queue position.
The level of service criterion for two-way STOP controlled intersections is somewhat different from the criterion used for signalized intersections. The primary reason for this is the difference that drivers expect a signalized intersection to carry higher traffic volumes than unsignalized

intersections. Additionally, several driver behavior conditions combine to make delays at signalized intersections less onerous than at unsignalized intersections.
The HCM provides procedures for calculating LOS on the minor street approaches and individual movements. It does not specify how a City must utilize that information. Depending on the availability of gaps, the minor approach might be operating at LOS D, E, or F while the overall intersection operates at LOS C or better. A minor approach that operates at LOS D, E, or F does not automatically translate into a need for a traffic signal. A signal warrant would still need to be met.
There are many instances where only a few vehicles are experiencing LOS D, E, or F on the minor approach while the whole intersection operates at an acceptable LOS. A signal is usually not warranted under such conditions.
Table 3.14-2 summarizes the relationship between delay and LOS for unsignalized intersections. At side-street stop-controlled intersections, the delay is calculated for each stop-controlled movement, the left-turn movement from the major street, as well as the intersection average. The intersection average delay and highest movement/approach delay are reported for side street stop-controlled intersections.
Table 3.14-2: Unsignalized Intersection LOS Criteria
LOS Driver’s Perception and Traffic Operation Description Delay in Seconds A Operations with very low delay occurring with favorable Progression and/or short cycle length.
< 10
B Operations with low delay occurring with good progression and/or short cycle lengths.
> 10–20
C Operations with average delays resulting from fair progression and/or longer cycle lengths. Individual cycle failures begin to appear. > 20–35
D Operations with longer delays due to a combination of unfavorable progression, long cycle lengths, or high volume-to-capacity (V/C) ratios. Many vehicles stop, and individual cycle failures are noticeable.
> 35–55
E Operations with high delay values indicating poor progression, long cycle lengths, and high V/C ratios. Individual cycle failures are frequent occurrences.
This is considered to be the limit of acceptable delay. > 55–80
F Operation with delays unacceptable to most drivers occurring due to over saturation, poor progression, or very long cycle lengths. > 80
Source: AMG, 2020.
The City of Patterson Guidelines for Traffic Impact Studies generally defines acceptable citywide unsignalized intersection operations as LOS D (35 seconds of delay per vehicle) or better during the morning and evening peak periods.

Significance Standards
City Standards
The following is the City’s criteria of significance to determine the potential impacts associated with a proposed project or action:
The City’s 2010 General Plan, Policy III.A.2 states that “The City shall endeavor to maintain a Level of Service (LOS) “D”, as defined by the 2000 Highway Capacity Manual (HCM) or subsequent revisions, on all streets and intersections within the City.”
County and Caltrans Standards
The minimum acceptable level of service standard for Stanislaus County roadway segments is LOS C.
Therefore, this report uses LOS C as the minimum acceptable standard and mitigation measures are recommended where service levels are below LOS C along roadways within Stanislaus County.
Facilities under the jurisdiction of Caltrans include freeway segments, ramps, ramp terminals, and arterials. Although Caltrans has not designated a LOS standard, Caltrans’ Guide for the Preparation of Traffic Impact Studies (December 2002) indicates attempts to maintain LOS of a State highway facility between the LOS “C/D” threshold. When existing State highway facilities are operating at higher levels of service than noted above, 20-year forecasts or general plan build-out analysis for the facility should be considered to establish equitable project contributions to local development impact fee programs that address cumulative traffic impacts.
Existing Traffic Conditions
Intersections
To accurately model the traffic condition, AMG created a Synchro traffic analysis model to determine the intersection LOS. The Existing Conditions traffic operations were evaluated based on levels of service criteria using Synchro. The macroscopic simulation model, Synchro, was used to evaluate several measures (such as lane geometries, signal optimization, signal phasing and traffic control) at the study intersections. The results of the LOS analysis for the existing intersections are shown in Table 3.14-3.

The I-5 Southbound off-ramp is currently stop control and it is the major gateway into the city from I5. All traffic at the southbound off-ramp needs to stop which contributes to LOS F condition. Very high left-turn volumes during the PM peak-hours from Sperry Avenue and Rogers Road contributed to the LOS E conditions respectively at the intersections of Sperry Avenue and SR-33 and Rogers Road and SR-33. A Project Report and Project Approval & Environmental Documentation (PA & ED) is currently underway and the final design is estimated to be completed by December 2019.3 Both intersections are currently stop controlled intersections and would operate at an acceptable LOS if signalized.

Bicycles
Bicycle facilities are classified by Caltrans into four distinct types of bikeway facilities, as generally described below:
Class I Bikeway (Bike Path). Provides a completely separate right-of-way and is designated for the exclusive use of bicycles and pedestrians with vehicle and pedestrian cross-flow minimized.
Class II Bikeway (Bike Lane). Provides a restricted right-of-way and is designated for the use of bicycles with a striped lane on a street or highway. Vehicle parking and vehicle/pedestrian crossflow are permitted.
Class III Bikeway (Bike Route). Provides for a right-of-way designated by signs or pavement markings for shared use with pedestrians or motor vehicles.
Class IV Bikeway (Separated Bikeway/Cycle Track). Provides a cycle track or protected bike lane, is for the exclusive use of bicycles, physically separated from motor traffic with a vertical feature.
The Class II facilities are generally found along the downtown portion of the existing urbanized area.
These facilities are found along parts of Las Palmas Avenue, Baldwin Road, American Eagle and ‘M’ Street.
The Class III Bike Route network is most prevalent in the Central Patterson area. However, there are gaps in the bike routes. Because of these gaps, it is difficult to fully traverse the city traveling north to south or east to west using the designated bicycle network.
Rail
Freight
The California Northern Railroad operates freight trains through Patterson, parallel to SR-33. The line connects Tracy and Los Banos, with multiple rail connections to local industries. The Union Pacific Railroad owns the tracks. Currently, there is one daily round trip train between Tracy and Los Banos through Patterson.
