Joshua Winter, Senior Planner 2 September 11, 2025 photographs, South Coast AQMD staff found that the nearest sensitive receptor (e.g., residential development) is located 90 feet from the project site.5 South Coast AQMD Comments
Contradiction in Project Hauling Assumptions
The IS/Draft MND states that excavation for the Project would reach a maximum depth of 4-6 feet below ground surface,disturbing approximately 123,501 square feet of soil.It further indicates that excavated soil would be reused on site and that no import or export of soil would be required (Section 2.2.6 of IS/Draft MND — Demolition and Construction). In contrast, Appendix A —Air Quality and Greenhouse Gas Technical Memorandum states that the Project would require H-1 removal of approximately 1,700 tons of roadway debris from the site and the import of approximately 900 cubic yards of soil during construction. These statements directly conflict with one another. Therefore, it is recommended that the Lead Agency to; 1) clarify whether the Project would involve import and/or export of materials; and 2) identify the appropriate landfill location and incorporate the corresponding haul distance into the CalEEMod modeling to accurately estimate hauling emissions.
South Coast AQMD Air Permits and Role as a Responsible Agency If implementation of the Proposed Project would require the use of new stationary and portable sources, including but not limited to emergency generators, fire water pumps, boilers, etc., air permits from South Coast AQMD will be required. The final CEQA document, should include a discussion about the potentially applicable rules that the Proposed Project needs to comply with.
Those rules may include, for example, Rule 201 — Permit to Construct,6 Rule 203 — Permit to Operate,' Rule 401 —Visible Emissions,' Rule 402—Nuisance,' Rule 403 —Fugitive Dust,10 Rule 1110.2 — Emissions from Gaseous and Liquid Fueled Engines,11 Rule 1113 — Architectural H-2 Coating,'2 Rule 1166 —Volatile Organic Compound Emissions from Decontamination of Soil," Rule 1179 — Publicly Owned Treatment Works Operations,14 Regulation XIII — New Source Review,15 Rule 1401 —New Source Review of Toxic Air Contaminants,16 Rule 1466—Control of Particulate Emissions from Soils with Toxic Air Contaminants,' Rule 1470 — Requirements for Stationary Diesel-Fueled Internal Combustion and Other Compression Ignition Engines," etc. It is important to note that when air permits from South Coast AQMD are required, the role of South Coast AQMD would change from a Commenting Agency to a Responsible Agency under CEQA.
In addition, if South Coast AQMD is identified as a Responsible Agency, per CEQA Guidelines Sections 15086, the Lead Agency is required to consult with South Coast AQMD. 5 Appendix A—Page 139.

Joshua Winter, Senior Planner 3 September 11, 2025 CEQA Guidelines Section 15096 sets forth specific procedures for a Responsible Agency, including making a decision on the adequacy of the CEQA document for use as part of the process for conducting a review of the Proposed Project and issuing discretionary approvals.
For these reasons, the final CEQA document should be revised to include a discussion about any and all new stationary and portable equipment requiring South Coast AQMD air permits,provide the evaluation of their air quality and greenhouse gas impacts, and identify South Coast AQMD as a Responsible Agency for the Proposed Project as this information will be relied upon as the H-3 basis for the permit conditions and emission limits for the air permit(s). Please contact South Coast AQMD's Engineering and Permitting staff at (909) 396-3385 for questions regarding what types of equipment would require air permits. For more general information on permits, please visit South Coast AQMD's webpage at https://www.aqmd.gov/home/permits .
Conclusion
The Lead Agency is recommended to revise the CEQA analysis to address the aforementioned comments and provide the necessary evidence to sufficiently support the conclusions reached. If the requested information and analysis are not included in the final CEQA document, either the Final MND or other type of CEQA document, the Lead Agency should provide reasons for not doing so. Pursuant to California Public Resources Code Section 21092.5(b)and CEQA Guidelines Section 15074,prior to approving the Proposed Project, the Lead Agency shall consider the MND for adoption together with any comments received during the public review process and notify each public agency when any public hearings are scheduled. Please provide South Coast AQMD H-4 with written responses to all comments contained herein prior to the adoption of the Final MND.
When responding to issues raised in the comments, detailed reasons supported by substantial evidence in the record to explain why specific comments and suggestions are not accepted must be provided. In addition,if the Lead Agency decides to adopt the Final MND,please provide South Coast AQMD with a notice of any scheduled public hearing(s).
Thank you for the opportunity to provide comments. South Coast AQMD staff is available to work with the Lead Agency to address any air quality questions that may arise from this comment letter.
Please contact Jivar Afshar, Air Quality Specialist, at [email protected] should you have any questions.

Hello,
We live with 20th as a cross street so this development on the end of 20th Street is a concern for us.
We would like to be sure that this SAWCo headquarters will not open public driving access to Campus. We see in their 1- plans that they will have a access road opening to Campus to their employee parking.
How many visitors does SAWCo anticipate having yearly? Will extra visitors be parking on 20th street if their visitor 1-2 parking gets full?
They only mention how many employees will work there.
As we look at the conceptual site plan,the driveway to the visitor parking lot feeds directly into Winston Ct. With the 1-3 road grade of 20th increasing near the end of the block and having additional traffic at this intersection, it would be safer if this driveway would be positioned further west so their driveway would be offset from Winston Ct.
We understand that this headquarters will be going in but we don't want to change our living location into a roadway for suppliers of SAWCo.
This immediate area is still primarily residential with expensive single family homes.
Stephanie and Matthew Zilmer

MITIGATION MONITORING AND REPORTING PROGRAM
This Mitigation Monitoring and Reporting Program (MMRP) is formulated based upon the findings of the Initial Study/Mitigated Negative Declaration (IS/MND) prepared for the San Antonio Water Company(SAWCo) Headquarters Project(Project).The MMRP, which is found in Table 1, lists mitigation measures recommended in the IS/MND prepared for the Project and identifies mitigation monitoring requirements.The Final MMRP must be adopted when the City of Upland (City) makes a final decision on the Project.
This MMRP has been prepared to comply with the requirements of State law (Public Resources Code Section 21081.6). State law requires the Lead Agency to adopt an MMRP when mitigation measures are required to avoid significant impacts.The MMRP is intended to ensure compliance with the mitigation measures identified in the IS/MND during implementation of the Project.
The MMRP is organized in a matrix format.The first two columns identify the potential impacts and corresponding mitigation measures.The third column, entitled "Timeframe for Implementation," refers to when monitoring will occur to ensure that the mitigating action is completed.The fourth column, entitled "Responsibility for Implementation," refers to the party responsible for implementing the mitigation measure. The fifth column, entitled, "Oversight of Implementation," refers to the party responsible for oversight or ensuring that the mitigation measure is implemented.

Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resource Code section 21080.3.1?If so,is there a plan for consultation that includes,for example,the determination of significance of impacts to tribal cultural resources,procedures regarding confidentiality,etc.? Native American consultation was conducted by the City in compliance with AB 52 and SB18.As part of the consultation process, a review of the Sacred Lands File(SLF) by the Native American Heritage Commission (NAHC) indicated that the results of the file search were positive and NAHC identified methodologies and contacts for conducting the required AB 52 and SB 18 tribal consultation.The NAHC recommended that 25 Native American individuals representing the Agua Caliente, Cahuila,Gabrieleno,Gabrielino Tongva, Morongo,Quechan,San Manuel,Santa Rosa,Serrano, and Soboba groups be contacted for information regarding cultural resources that could be affected by the Project.
The City provided notice of the Project via certified mail on March 5,2025,to Native American tribal contacts provided by the NAHC,as well as local Native American tribal representatives that previously requested to be notified of future projects proposed by the City in compliance with AB 52 and SB18. The City received responses from the Yuhaaviatam of San Manuel Nation (San Manuel Nation)and the Gabrieleno Band of Mission Indians—Kizh Nation (Kizh Nation).
Consultation with Native American tribes was conducted by the City of Upland in accordance with Public Resource Code section 21080.3.1 as described further in Section 4.18,Tribal Cultural Resources.

2.1.2.1 Surrounding Land Uses
As shown in Figure 2-2,the Project site is generally surrounded by a mix of residential,commercial, and industrial uses.To the north,across East 20th Street,are single-family residences.To the east, undeveloped open space owned by Southern California Edison Company,which borders the site, with commercial and industrial uses further east, including a concrete supplier and gravel mine.To the south,SR-210 separates the site from two large water storage tanks, single-family residences, and commercial uses.To the west, across Flower Court, are additional single-family residential homes.
2.1.2.2 Land Use and Zoning
The Project site is currently designated Single-Family Residential Low(SFR-L) in the City of Upland General Plan Land Use Map'.The SFR-L designation provides for the development of detached single-family units and allows for a density of zero to four dwelling units per acre.The City of Upland Zoning Map identifies the Project site as single-family residential RS-10,000 IRS-10), intended for lots with a minimum area of 10,000 square feet,accommodating no more than one single-family dwelling and its accessory buildings.These lots are characterized by larger single-family dwellings (i.e.,a 1,600-square-foot-minimum floor area),ample open space, lush landscaping, and medium separations between single-family dwellings and/or permitted accessory buildings.
2.2 PROPOSED PROJECT
The Project would result in the construction of a new SAWCo headquarters and associated improvements as described in detail below.
2.2.1 Rezone and General Plan Amendment
The proposed use is not currently permitted at the site under the current SFR-L General Plan land use designation and RS-10 zoning.To comply with the City's General Plan and zoning regulations, the Project would require a General Plan amendment and a zone change to Public Utilities(PU) land use designation and Public/Institutional (PB/I)zoning.The PU designation accommodates landfills, flood control/recharge facilities, and public utilities, including gas,electricity, and water.The purpose of the PB/1 zone is to allow for public and quasi-public facilities that serve the City's residents and visitors.The PU designation and PB/I zone permit a maximum Floor Area Ratio (FAR) of 0.5.
2.2.2 Building Program
As shown in Figure 2-3,the Project would result in the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard,driveway, parking,solar cover, landscaping,and utility improvements.
The headquarters building would feature office space, meeting and conference rooms,a lobby,an archive room, a break room,two Americans with Disabilities Act(ADA) restrooms,a quiet room, 1 City of Upland.2015a.City of Upland General Plan Update,Figure LU-1 General Plan Land Use.

a copy room,and a work area.The maintenance building would include storage space,an outdoor welding area,a motor repair room, electrical rooms, an ADA restroom,a locker room, and a maintenance office/break room.The existing water storage tank, pump station,and signal buildings and tower would remain in place.The buildings would be a maximum height of 23 feet and have a FAR of 0.07.Approximately ten people are expected to be employed on site.
2.2.3 Open Space and Landscaping
The Project would include a citrus grove buffer along the eastern half of the northern property line, along with various trees and shrubs around the parking areas and the main headquarters building.
Approximately 46,077 square feet of landscaped area would be provided. Up to two of the existing street trees would be removed to accommodate the driveway off East 20th Street, and various shrubs and associated grassland would be removed to accommodate the driveway off Campus Avenue and East 20th Street.The three existing trees at the southwestern corner of the Project site would remain in place,and 51 new ornamental trees and 64 new citrus trees would be planted as part of the Project's landscape design.
2.2.4 Access,Circulation,and Parking
Vehicular access to the Project site would be provided via two paved driveways with gates for security.Two new driveways would be constructed,as shown in Figure 2-3. One new 26-foot-wide driveway would be constructed off of East 20th Street along the northern property boundary that would access the visitor and customer parking area. An additional 25-foot-wide driveway would enter the Project site at the northeastern corner and would connect to the intersection of Campus Avenue and East 20th Street approximately 275 feet east of the Project site.This driveway would cross undeveloped land owned by the Southern California Edison company and require an easement.This driveway would enter the Project site at the northeastern corner and run south along the eastern property line to access the covered employee parking area, maintenance building, and covered truck parking area.This driveway would serve as a SAWCo maintenance vehicle private access road and would be secured by a 20-foot-wide,5-foot-tall steel gate located just west of the Campus Avenue and East 20th Street intersection that would be open during business hours. No public access will be allowed through this new driveway.
The visitor and customer parking lot would be located south of the citrus grove and north of the main headquarters building and would provide 14 surface parking spaces, including two ADA compliant parking spots.The employee parking area would be located east of the main headquarters building,would be covered by photovoltaic panels, and would include 14 surface parking spaces,including two ADA compliant parking spots.The Project would also provide eight covered truck parking spots west of the maintenance building.
2.2.5 Utilities and Infrastructure
The Project site is in an urban area with existing utilities, including water,sanitary sewer, storm drainage, electricity,and telecommunications. Natural gas is not proposed as part of the Project.
The following sections detail the utility connections.

LC SAN AN,ONIO WATER COMPANY HEAD QUARTERS PROJECT INITIAL STUDY/MITIGATED NEGATIVE DECLARATION _.1/ UPLAND,CALIFORNIA AuGusr 2025
2.2.5.1 Water
The City owns and operates its water distribution system,serving residential,commercial,and industrial users within City limits, including the Project site.The Project would include new on-site water lines that would be constructed and connected to existing nearby water main lines in conformance with City standards.
2.2.5.2 Wastewater
The City also owns and operates the local sewer lines with wastewater treatment provided by reclamation facilities maintained by the Inland Empire Utilities Agency(IEUA).The Project would include new on-site sanitary sewer lines connected to existing nearby sanitary sewer main lines in compliance with City standards.
2.2.5.3 Stormwater
The existing water storage tank, structures, paving,and other impervious surfaces account for approximately 24,793 square feet(11.6 percent)of the 4.92-acre Project site.The remaining 189,566 square feet are pervious surfaces consisting of undeveloped exposed soil.There is currently no existing stormwater infrastructure on the Project site.Stormwater flows to the southwest to a natural ravine that discharges into an existing ditch along the freeway right-of-way which discharges to a City of Fontana storm drain along Poplar Avenue.
Post-construction,approximately 71,697 square feet(33.4 percent)of the Project site would be covered by impervious surfaces,while approximately 142,660 square feet(66.6 percent)would be covered by pervious surfaces, consisting of a landscaped area, undeveloped space,and bioretention area.Stormwater drains and catch basins would be installed throughout the site,connecting to an infiltration basin and an underground storage infiltration system that would be used for stormwater control,treatment,and infiltration.
2.2.5.4 Electricity
Electrical power is provided to the Project site and surrounding area by the Southern California Edison Company.The Project would connect to existing overhead electricity lines along East 206 Street.While City policy generally requires utility lines to be placed underground as part of development or infrastructure improvement projects,the City may exercise discretion to exempt certain components from this requirement'.The existing transmission lines located in front of the Project site would not be disturbed as part of the proposed activities. However, any new lateral connections associated with the Project would be installed underground on the site.
2.2.6 Demolition and Construction
Excavation for the Project would reach a maximum depth of 4-6 feet below ground surface, disturbing approximately 123,501 square feet of soil. It is anticipated that excavated soil would be used on site, and would not require the import or export of soil materials. Construction of the Project is anticipated to begin in 2025 and be completed by the end of 2026. 2 City of Upland Municipal Code.Chapter 12.28.

d) Create a new source of substantial light or glare which would ❑ ❑ ® ❑ adversely affect day or nighttime views in the area?
a. Would the project have a substantial effect on a scenic vista?(Less Than Significant Impact) In Upland, a scenic vista is defined as a view of undisturbed natural lands exhibiting a unique or unusual feature that comprises an important or dominant portion of the viewshed. Natural visual resources include mountain ranges, hillsides, low-lying valley,and streams.Scenic vistas may also be represented by a particular distant view that provides visual relief from less attractive views of nearby features.The City's General Plan does not designate any official scenic views or vistas within the City; however,scenic resources within Upland include surrounding mountains and hillsides located north of the City, including the San Gabriel Mountains and Mount Baldy.Additionally,the northern portion of the City is comprised of hilly terrain,which provides scenic views of the City and surrounding region.The General Plan also identifies the following Scenic Roadways: Euclid Avenue, Mountain Avenue, Foothill Boulevard,and Benson Avenue.' The Project site is located in the northern portion of the City in a relatively flat area primarily surrounded by a mix of residential, commercial, and industrial development.The San Gabriel Mountains and Mount Baldy are visible to the north; however,these views are partially obstructed by existing development and trees. Euclid Avenue is located approximately 0.27 mile to the west; however,the Project site is not visible from Euclid Avenue due to existing development and trees.
All other identified Scenic Roadways are located over a mile from the Project site and the Project 3 City of Upland.2015b.Final Program Environmental Impact Report General Plan Update(GPU 08-03),Zoning Code Update(ZCU 08-03),Climate Action Plan,and Cable Airport Land Use Compatibility Plan Update 5CN No. 2012041006).September 28.

site is not visible from these corridors due to existing development,trees,and intervening topography.
The Project site is visible from its northern and western boundaries by vehicles and pedestrians traveling along East 20th Street and Flower Court, respectively.The Project site is also partially visible from North Campus Avenue and East 20th Street,the intersection of which would connect to the new driveway associated with the Project.The surrounding views primarily consist of urban views of single-family residences to the north and west.Open space is visible in foreground views to the east, with commercial development visible in background views.Views to the south are largely obstructed by an existing masonry wall that runs along the southern property boundary.
Buildings in the vicinity of the Project site primarily include residential and commercial buildings that range from one to two stories in height.The proposed headquarters and maintenance buildings would be two stories with a maximum height of 23 feet.As such,the height and mass of the proposed structure would be similar to the surrounding development. Furthermore,the Project would include new landscaping and trees along the perimeter of the Project site and within the surface parking lot,shielding the proposed building and improving the site's overall visual appearance.Therefore, public views of the Project site from surrounding areas would generally blend with surrounding urban development.The Project would not result in a substantial adverse effect on a scenic vista and this impact would be less than significant. b. Would the project substantially damage scenic resources, including,but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway?(No Impart) The Project is not located within the vicinity of any State Scenic Highways.4 State Route(SR) 142 is the nearest eligible State Scenic Highway, which is located approximately 11.6 miles southwest of the Project site.The nearest Officially Designated State Scenic Highway is SR-2, which is located 16 miles north of the Project site. Due to distance,topography,and intervening development, no portion of the Project site or surrounding area is visible from the officially designated portion of 5R-2 or the eligible portion of SR-142.Therefore, no impacts to scenic resources,including trees, rock outcroppings,or historic buildings visible from a State Scenic Highway would occur. No mitigation is required.
c. In non-urbanized areas, would the project substantially degrade the existing visual character or quality of public views of the site and its surroundings?(Public views are those that are experienced from a publicly accessible vantage point.)If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? (Less Than Significant Impact)
The Project site is located within an urbanized area.As noted in Chapter 2.0, Project Description,the Project site is currently located within the single-family residential RS-10,000(RS-10) zone but a zone change to Public/Institutional (PB/I)zoning is proposed.The purpose of the PB/I zone is to 4 California Department of Transportation(Caltrans).2018.California State Scenic Highway System Map.

allow for public and quasi-public facilities that serve Upland residents and visitors. Permitted uses in the PB/I zone include public schools; parks and playgrounds;community centers; museums,cultural, and interpretive facilities; public libraries;governmental offices; police and fire stations;and hospitals.
The PB/I zone allows a maximum floor area ratio(FAR)of 0.5 and a maximum structure height of 45 feet.The Project would have a FAR of 0.07 and a maximum structure height of 23 feet.Structure setback standards in the PB/I Zone include a minimum 20-foot front setback and a minimum 20-foot rear setback.The Project would have a front setback of 152.8 feet and a rear setback of 35.1 feet.
Furthermore,the Project would be required to undergo Development Plan Review per the City's Municipal Code Chapter 17.44.030 which would provide for the review of the physical improvements to the Project site,including the overall building scale, massing, and design to ensure compatibility and compliance with City requirements governing scenic quality.As detailed in the City's Municipal Code Chapter 17.44.030(H. Findings),the approval of an application for Development Review would require compliance with applicable standards in the Zoning Ordinance, other City ordinances,the General Plan, and any other applicable community or specific plans, and the following findings:
1. The design and layout of the proposed project will not interfere with the use and enjoyment of existing and future neighboring properties and structures.
2. The proposed architectural design makes use of appropriate materials,texture,and color, and will remain aesthetically appealing and appropriately maintained.
3. The proposed landscaping design, including color, location,size,texture,type, and coverage of plant materials, as well as provisions for irrigation, maintenance, and protection of landscaping elements,will complement structures and provide an attractive environment.
4. The proposed design will not be materially detrimental to the public health,safety,or welfare, or be injurious to the property or improvements in the vicinity of the proposed project.
Therefore,with approval of the required Development Plan Review,the Project would not conflict with applicable zoning and other regulations governing scenic quality,and impacts related to applicable zoning and other regulations governing scenic quality would be less than significant. No mitigation is required.
d. Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?(Less Than Significant Impact) The Project site is located in an urbanized area,which is subject to preexisting exterior lighting from surrounding residential,commercial,and industrial development and existing street lighting.The Project would introduce new sources of light and glare to the area in the form of new windows, interior lighting,and exterior safety and security lighting. However, new sources of light and glare associated with the Project would not be substantial in the context of existing lighting sources and lighting associated with the Project would be consistent with surrounding residential, commercial, p:\2024\2O241723 San Antonia Driveway Expansion\PRODUCTS\CEOA Publit Review❑raft\5an Antonio Water Headquarters ISMND_48.08.25.dacx(08102125) 4-3

and industrial uses. Furthermore,the Project would be subject to the following standards related to outdoor lighting per Chapter 17.14 Outdoor Lighting,of the City's Municipal Codes:
• Light trespass that results in glare is prohibited. • All non-residential outdoor lighting shall be located, adequately shielded,and directed such that no direct light falls outside the property line or into the public right-of-way. • Luminaires shall be so designed and shielded by horizontal cutoff to eliminate all light directed above the horizontal plane.The lower edge of the luminaires housing shall extend below the entire light source and all glassware so that any light emitted above the horizontal is eliminated.
Light-directing refractors shall be considered to be light sources. • Outdoor lighting shall comply with the State of California Title 24 Energy Efficiency Standards outdoor lighting requirements. If a conflict between the requirements of this chapter and the State of California Title 24 Energy Efficiency Standards arises,that which produces the least glare shall apply.
• Lighting that flashes,flickers, blinks, changes color, or changes intensity such that it is distracting or may be confused with traffic or emergency signals shall be prohibited. • Parking area luminaires shall be no taller than 20 feet as measured from the adjacent grade to their tallest point.Taller poles may be approved by the Development Services Director. • Lighting,where provided to illuminate parking,sales,or display areas shall be hooded or shielded.
Daytime glare would not be substantial as no highly-reflective glass elements are proposed as part of the Project.Therefore,the Project would not create a new source of substantial light or glare which would adversely affect day or nighttime views in the area.With adherence to Title 24 and Municipal Code requirements,the Project would have a less than significant impact related to new sources of substantial light and glare,and no mitigation is required.

4.2 AGRICULTURE AND FORESTRY RESOURCES
In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland,are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the State's inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment Project; and the forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board.

a. Would the project conflict with or obstruct implementation of the applicable air quality plan? (Less Than Significant impact)
The Project site is located within the South Coast Air Basin(Basin),which includes the non-desert portions of Los Angeles, Riverside, and San Bernardino Counties and all of Orange County, and is within the jurisdictional boundaries of the South Coast Air Quality Management District(SCAQMD).
The SCAQMD administers the Air Quality Management Plan(AQMP)for the Basin,which is a comprehensive document outlining an air pollution control program for attaining all California Ambient Air Quality Standards(CAAQS) and National Ambient Air Quality Standards(NAAQS).8 The most recent adopted AQMP is the 2022 AQMP, which was adopted by the SCAQMD Governing Board in December 2022.The 2022 AQMP builds upon measures already in place from previous AQMPs. It also includes a variety of additional strategies such as regulation,accelerated deployment of available cleaner technologies(e.g.,zero emissions technologies,when cost-effective and feasible,and low nitrogen oxides(NOx)technologies in other applications), best management ' LSA Associates, Inc.

practices,co-benefits from existing programs(e.g.,climate and energy efficiency), incentives,and other Clean Air Act(CAA) measures to achieve the 2015 8-hour ozone standard.
The City of Upland General Plan is consistent with the Southern California Association of Governments(SLAG) Regional Comprehensive Plan Guidelines9 and the SCAQMD AQMP.The revisions to accommodate this Project will not change that. Pursuant to the methodology provided in the SCAQMD CEQA Air Quality Handbook,1°consistency with the Basin AQMP is affirmed when a project(1)would not increase the frequency or severity of an air quality standards violation or cause a new violation, and(2) is consistent with the growth assumptions in the AQMP. Consistency review is presented as follows:
1. The Project would result in short-term construction and long-term operational pollutant emissions that are all less than the CEQA significance emissions thresholds established by SCAQMD,as demonstrated below under Section 4.3.b;therefore,the Project would not result in an increase in the frequency or severity of an air quality standards violation or cause a new air quality standards violation.
2. The CEQA Air Quality Handbook indicates that consistency with AQMP growth assumptions must be analyzed for new or amended General Plan elements,Specific Plans,and significant projects.
Significant projects include airports,electrical generating facilities, petroleum and gas refineries, designation of oil drilling districts,water ports, solid waste disposal sites,and offshore drilling facilities;therefore,the Project is not defined as significant.According to SCAG's Connect SoCal:
The 2024-2050 Regional Transportation Plan/Sustainable Communities Strategy(2024-2050 RTP/SCS),the City of Upland's households and jobs are forecast to increase by approximately 5,700 households and 4,900 jobs, respectively, between 2019 and 2050. Based on information provided by the Project Applicant,the Project would have approximately 10 employees.The number of new employees generated by the Project would fall within the 4,900 projected jobs for the City.Accordingly,the Project's labor demand would not be expected to substantially increase population, households,or employment in Upland since the number of employees associated with the Project would be a small fraction (approximately 0.2 percent)of the projected job growth for the City.Therefore, implementation of the Project would not interfere with SCAG's ability to implement the regional strategies outlined in the 2024-2050 RTP/SCS.
Based on the consistency analysis presented above,the Project would be consistent with the regional AQMP.Therefore,the Project would not conflict with or obstruct implementation of the applicable air quality plan. Impacts would be less than significant,and no mitigation is required. 9 Southern California Association of Governments(SCAG).2008.Final 2008 Regional Comprehensive Plan.

b. Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard?(Less Than Significant Impact)
The Basin is currently designated as nonattainment for the federal and State standards for ozone(or smog) (03)and particulate matter less than 2.5 microns in size(PM2.5). In addition,the Basin is in nonattainment for the particulate matter less than 10 microns in size(PM10)standard.11 The Basin's nonattainment status is attributed to the region's development history. Past, present,and future development projects contribute to the region's adverse air quality impacts on a cumulative basis.
By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of an ambient air quality standard. Instead,a project's individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project's contribution to the cumulative impact is considerable,then the project's impact on air quality would be considered significant.The following analysis assesses the potential Project-level air quality impacts associated with construction and operation of the Project.
Construction Emissions. During construction,short-term degradation of air quality may occur due to the release of particulate matter emissions(i.e.,fugitive dust)generated by ground disturbance, paving, and other activities. Emissions from construction equipment are also anticipated and would include carbon monoxide(CO), NOx,volatile organic compounds(VOCs),directly emitted PM2 5 or PM1a,and toxic air contaminants such as diesel exhaust particulate matter.
Project construction activities would include grubbing and land clearing,grading,drainage, utilities, building construction,and paving activities.Sources of fugitive dust would include disturbed soils at the construction site. Unless properly controlled,vehicles leaving the site would deposit dirt and mud on local streets,which could be an additional source of airborne dust after it dries. PM10 emissions would vary from day to day,depending on the nature and magnitude of construction activity and local weather conditions. PM10 emissions would depend on soil moisture,silt content of soil, wind speed,and amount of operating equipment. Larger dust particles would settle near the source,whereas fine particles would be dispersed over greater distances from the construction site.
Water or other soil stabilizers can be used to control dust, resulting in emission reductions of 50 percent or more.SCAQMD has established Rule 403: Fugitive Dust,which would require the Project Applicant to implement measures that would reduce the amount of particulate matter generated during the construction period.The Rule 403 measures that were incorporated in this analysis include:12
• Water active sites at least twice daily(locations where earth disturbance is to occur shall be thoroughly watered prior to earthmoving).

• Cover all trucks hauling dirt,sand,soil, or other loose materials,or maintain at least 2 feet (0.6 meter)of freeboard (vertical space between the top of the load and the top of the trailer) in accordance with the requirements of California Vehicle Code Section 23114. • Reduce traffic speeds on all unpaved roads to 15 miles per hour or less.
In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO,sulfur oxides(SOx}, NOx,VOCs,and some soot particulate(PM2.5and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area,CO and other emissions from traffic would increase slightly while those vehicles idle in traffic.These emissions would be temporary in nature and limited to the immediate area surrounding the construction site.
Construction emissions were estimated for the Project using California Emissions Estimator Model version 2022.1 (CalEEMod) and are summarized in Table 4.3.A.CalEEMod output sheets are included in Appendix A.

The results shown in Table 4.3.A indicate the Project would not exceed the significance criteria for daily VOCs, NOx,CO,SOx, PM10, or PM2.5 emissions.Therefore,construction of the Project would not result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is in nonattainment under an applicable federal or State AAQS. Impacts would be less than significant, and no mitigation is required.
Operational Air Quality Impacts. Long-term air pollutant emissions associated with operation of the Project include emissions from area,energy,and mobile sources. Area-source emissions include architectural coatings,consumer products,and landscaping. Energy-source emissions result from utility plants generating electricity used by the Project.Typically, energy-source emissions would also include emissions from natural gas consumption; however,the Project would not use natural 4-10 P:\2024\20241723_5an Antonio Driveway Expansion\PRODUCTS\CEQA\Public Review nraft45an Antonio Water Headquarters 15MND_08.0S25.docx(02108125)

Additionally, PMlo emissions result from running exhaust,tire and brake wear,and the entrainment of dust into the atmosphere from vehicles traveling on paved roadways.

The results shown in Table 4.3.B indicate the Project would not exceed the significance criteria for daily VOCs, NOx, CO,SON, PM/0,or PM2.s emissions.Therefore,operation of the Project would not result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is in nonattainment under applicable NAAQS or CAAQS. Impacts would be less than significant,and no mitigation is required.
c. Would the project expose sensitive receptors to substantial pollutant concentrations?(Less Than Significant Impact)
Sensitive receptors are defined as people that have an increased sensitivity to air pollution or environmental contaminants.Sensitive receptor locations include schools, parks and playgrounds, daycare centers, nursing homes, hospitals,and residential dwelling units.The nearest sensitive receptors are the existing single-family residences to the west approximately 90 feet from the Project boundary.13 Although the majority of the construction activities would occur in the eastern half of the Project site much further from these residences,this analysis assumes that at some point construction equipment could operate along the western boundary of the Project site.As the Project's operational emissions would occur in the eastern portion of the Project site around the 13 Distance for construction air quality impact potential includes the assumption that heavy construction equipment would operate adjacent to the proposed project boundary,which is approximately 90 feet from the center of the nearest off-site structures where a person would live.

proposed buildings,the closest sensitive receptors to these emissions are the existing single-family residences to the north approximately 300 feet from the centroid of the operational area.
The following section describes the potential impacts on sensitive receptors from construction and operation of the Project and includes a CO hot-spot analysis and a localized significance analysis.
Long-Term Microscale(CO Hot-Spot)Analysis.Vehicular trips associated with the Project would contribute to congestion at intersections and along roadway segments in the vicinity of the Project site. Localized air quality impacts would occur when emissions from vehicular traffic increase as a result of the Project.The primary mobile-source pollutant of local concern is CO,a direct function of vehicle idling time and,thus, of traffic flow conditions. CO transport is extremely limited. Under normal meteorological conditions,it disperses rapidly with distance from the source. However, under certain extreme meteorological conditions,CO concentrations near a congested roadway or intersection may reach unhealthful levels,thereby affecting local sensitive receptors(e.g., residents, schoolchildren,the elderly,and hospital patients).
Typically, high CO concentrations are associated with roadways or intersections operating at unacceptable levels of service or with extremely high traffic volumes. In areas with high ambient background CO concentrations, modeling is recommended to determine a project's effect on local CO levels.
An assessment of Project-related impacts on localized ambient air quality requires that future ambient air quality levels be projected. Existing CO concentrations in the immediate Project vicinity are not available.Ambient CO levels monitored at the Fontana-Arrow Highway station (the closest station to the Project site),showed a highest recorded 1-hour concentration of 1.9 parts per million (ppm)(the State standard is 20 ppm)and a highest 8-hour concentration of 1.4 ppm(the State standard is 9 ppm) from 2021 to 2023.The highest CO concentrations would normally occur during peak traffic hours; hence,CO impacts calculated under peak traffic conditions represent a worst-case analysis. Reduced speeds and vehicular congestion at intersections result in increased CO emissions.
The Project is expected to generate 85 new average daily trips,with 8 net new trips occurring in the a.m. peak hour and 10 net new trips occurring in the p.m. peak hour.14 Therefore,given the extremely low level of CO concentrations in the Project area and the lack of traffic impacts at any intersections, Project-related vehicles are not expected to result in CO concentrations exceeding the State or federal CO standards. No CO hot spots would occur, and the Project would not result in any Project-related impacts on CO concentrations.
Localized Significance Thresholds Analysis.A Localized Significance Thresholds(LST)analysis was completed to show the construction and operational impacts to the nearest sensitive receptors to the Project site, based on a 4.92-acre daily disturbance area for construction and a 4.92-acre area for operations.As previously discussed,the nearest sensitive receptors are 90 feet to the west during construction and 300 feet to the north after construction during operations.
By design,the localized impact analysis only includes on-site sources; however,the CalEEMod outputs do not separate on-site and off-site emissions for mobile sources. For a worst-case scenario 14 LSA.2024b. Traffic Impact Analysis San Antonio Water Headquarters Project.

assessment,the emissions detailed in Table 4.3.0 assume all area-and energy-source emissions would occur on site,and 5 percent of the Project-related new mobile sources(which is an estimate of the amount of Project-related vehicle travel would occur on site).Considering the total trip length included in CalEEMod,the 5 percent assumption is conservative.Table 4.3.0 shows the results of the LST analysis during Project construction and operation.

Ibs/day=pounds per day PM,.5=particulate matter less than 2.5 microns in size LSTs=Localized Significance Thresholds PMio=particulate matter less than 10 microns in size As shown in Table 4.3.C,the Project would not result in an exceedance of a SCAQMD LST during Project construction or operation. During construction,construction contractors would be required to implement measures to reduce or eliminate emissions by implementing SCAQMD Rule 403 dust control measures.15 In addition,the maximum daily emissions associated with Project construction emissions indicate the Project would not exceed the significance criteria for VOCs, NO,CO,SON, PM10,or PM2,5 emissions.Therefore,the emissions associated with construction of the Project would not be expected to exceed the most stringent applicable federal or State ambient air quality standards. It should be noted that the ambient air quality standards are developed and represent levels at which the most susceptible persons(children and the elderly)are protected. In other words,the ambient air quality standards are purposefully set low to protect children,the elderly, and those with existing respiratory problems.Therefore,given the temporary nature of short-term construction impacts,and the absence of any exceeded threshold of significance related to construction impacts,construction of the Project would not exceed SCAQMD thresholds and would not expose nearby sensitive receptors to substantial pollutant concentrations. No significant health risk would occur from Project construction emissions.
Similarly,as indicated in Table 4.3.B, operation of the Project would not exceed the significance criteria for VOCs, NOx,CO,SOx, PM10, or PM2.5 emissions. 15 SCAQMD.2024b.Op.cit.

The SCAQMD's numeric regional mass daily emissions thresholds are based in part on Section 180 (e)of the federal Clean Air Act. It should be noted that the numeric regional mass daily emissions thresholds have not changed since their adoption as part of SCAQMD's CEQ4 Air Quality Handbook published in 1993 (over 30 years ago).16 The numeric regional mass daily emission thresholds are also intended to provide a means of consistency in significance determination within the environmental review process.
As noted in the Brief of Amicus Curiae by the SCAQM D,17 the SCAQMD has acknowledged that for criteria pollutants, it would be extremely difficult, if not impossible,to quantify health impacts for various reasons,including modeling limitations as well as where in the atmosphere air pollutants interact and form.
Additionally,the SCAQMD acknowledges that health effects quantification from 03,as an example, is correlated with the increases in ambient levels of 03 in the air(concentration)that an individual person breathes.The SCAQMD goes on to state that it would take a large amount of additional emissions to result in a modeled increase in ambient 03 levels over the entire region.The SCAQMD states that based on its own modeling in its 2012 AQMP,18 a reduction of 432 tons(864,000 pounds) per day of NOx and a reduction of 187 tons(374,000 pounds) per day of VOCs would reduce 03 levels at the highest monitored site by only 9 parts per billion (ppb).As such,the SCAQMD concludes that it is not currently possible to accurately quantify 03-related health impacts caused by NOx or VOC emissions from relatively small projects(defined as projects that are not regional in scope) due to photochemistry and regional model limitations(see page 11 of the SCAQMD Brief of Amicus Curiae).
To underscore this point,the SCAQMD goes on to state that it has only been able to correlate potential health outcomes for very large emissions sources.As part of its rulemaking activity, specifically 6,620 pounds per day(Ibs/day) of NOx and 89,180 lbs/day of VOCs were expected to result in approximately 20 premature deaths per year and 89,947 school absences due to 03.As identified in Tables 4.3.A and 4.3.B, NOx and VOC emissions during Project construction and operation would be well below 6,620 Ibs/day of NOx and 89,180 Ibs/day of VOCs.
Due to the small size of the Project in relation to the overall Basin,the level of emissions is not sufficiently high to use a regional modeling program to correlate health effects on a Basin-wide level.On a regional scale,the quantity of emissions from the Project is incrementally minor. Because the SCAQMD has not identified any other methods to quantify health impacts from small projects and due to the size of the Project, it is speculative to assign any specific health effects to small Project-related emissions. However, based on this localized analysis,the Project would not expose sensitive receptors to substantial pollutant concentrations.Therefore,the Project would not expose lfi SCAQMD. 1993.Op.cit.

sensitive receptors to substantial levels of pollutant concentrations,impacts would be less than significant.
d. Would the project result in other emissions(such as those leading to odors)adversely affecting a substantial number of people?(Less Than Significant Impact) Heavy-duty equipment on the Project site during construction would emit odors, primarily from equipment exhaust. However,the construction activity would cease after individual construction is completed. No other sources of objectionable odors have been identified for the Project during construction.
The Project would be required to comply with SCAQMD Rule 402.SCAQMD Rule 402 regarding nuisances states, "A person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public,or which endanger the comfort, repose, health or safety of any such persons or the public,or which cause,or have a natural tendency to cause, injury or damage to business or property."
Examples of odor-generating projects are wastewater treatment plants, compost facilities, landfills, solid-waste transfer stations,fiberglass manufacturing facilities, paint/coating operations(e.g.,auto body shops),dairy farms, petroleum refineries,asphalt batch plants,chemical manufacturing,and food manufacturing facilities.The Project would include a new 3,698-square-foot SAWCo headquarters and associated improvements and a 4,066-square-foot maintenance building, maintenance yard, driveway, parking,solar cover,and landscaping;therefore,the Project would not include land uses that would be expected to generate odors.
Once operational,the Project would involve minor odor-generating activities(e.g.,trash, landscape equipment,application of exterior paints,etc.). However, unlike the odor-generating land uses identified above,these are not considered potential generators of odor that could affect a substantial number of people. Further, Project-generated refuse would be stored in covered containers and would be removed at regular intervals to minimize odors. In addition,the Project would be required to comply with the California Department of Resources Recycling and Recovery (CalRecycle)waste diversion program and recycling of solid and organic waste.Therefore, operational uses are not anticipated to emit any objectionable odors.Therefore,the Project would not result in other emissions (e.g.,those leading to odors)adversely affecting a substantial number of people. Impacts would be less than significant,and no mitigation is required.

The Project site is generally flat and largely undeveloped.The site itself primarily consists of nonnative,disturbed vegetation. Existing developments include a one-million-gallon water storage tank located underground at the northwestern corner of the parcel, a pump station located at the southwestern corner of the parcel,and a cellular building and tower located at the southeastern corner of the parcel.The disturbed vegetation occurring within the Project site is considered low-quality habitat for most native wildlife species.
A literature review and records search were conducted to determine which special-status biological resources have the potential to occur on or within the general vicinity of the Project site. In addition to the literature review,a general habitat assessment or field investigation of the Project site was conducted to document existing conditions and assess the potential for special-status biological resources to occur within the Project site.
No special-status plant or wildlife species were observed during the field survey.The Biological Resources Assessment identifies special-status plant and animal species with California Natural Diversity Database(CNDDB) record search occurrence and includes detailed information about each species' habitat and distribution,as well as State and federal status designations and the probability of occurrence within the Project disturbance limits.As detailed in the Biological Resources Assessment prepared for the Project, no regionally occurring special-status animal species are expected to be present on the Project site or to be adversely affected by the Project due to the lack of suitable habitats and the developed/disturbed conditions within the direct disturbance limits of the Project.Additionally, no federal or State-listed endangered plant species are expected to occur on the Project site due to the lack of suitable soils.
Burrowing owls,a non-listed State species of special concern, have a low to moderate probability of occurrence within the Project site. Burrowing owls inhabit open country across much of North America,typically occupying ground squirrel burrows in open,dry grasslands,agricultural and range lands,and other developed/ornamental areas.They often utilize man-made structures and avoid tall,thick vegetation and brush. While the Project site does have disturbed soils and minimal vegetation cover conducive to burrowing owl usage, no burrows or signs of burrowing owls were observed during the field survey. Nevertheless, Mitigation Measure(MM) BIO-1 would be required to avoid impacts to western burrowing owl prior to commencement of construction.

MM BI0-1 Burrowing Owl Clearance Survey. Fourteen days prior to the commencement of Project activities,a qualified biologist will conduct a Presence/Absence survey of suitable habitat on the Project site as well as survey for signs of scat/burrow usage.
If burrowing owls/active burrows are directly observed within the Project site during the preconstruction survey,a suitable buffer will be placed around the active burrow as determined by a qualified biologist and avoided until the individuals leave of their own accord.Additionally, if burrowing owl is found during the preconstruction survey,the Project proponent will need to inform the California Department of Fish and Wildlife(CDFW)and the United States Fish and Wildlife Service(USFWS)and prepare a Burrowing Owl Protection and Relocation Plan for approval by these agencies prior to initiating ground disturbance.
There are trees adjacent to and within the Project site and construction activities could result in impacts to nesting bird species. Nesting birds are protected pursuant to the Migratory Bird Treaty Act(META)and the California Fish and Game Code(Sections 3503, 3503.5,3511, and 3513 prohibit the take, possession,or destruction of birds,their nests or their eggs).To avoid impacts to nesting birds from implementation of the Project,a pre-construction nesting bird survey would be required prior to removal of any landscaped vegetation, as detailed in MM B10-2.
MM 13I0-2 Nesting Bird Clearance Survey.The Project's construction activities will occur, if feasible, between September 15 and January 31 (outside of nesting bird season) in an effort to avoid impacts to nesting birds. If activities must occur within nesting bird season(February 1 to September 15),a qualified biologist will conduct a pre- construction survey no more than 3 days(72 hours) prior to any construction activities and vegetation removal. Should nesting birds be found,an exclusionary buffer will be established by the qualified biologist.The buffer will be clearly marked in the field by construction personnel under guidance of the qualified biologist. No construction activities will be allowed within this zone until the qualified biologist determines that the young have fledged,or the nest is no longer active.
To the greatest extent feasible,tree trimming/removal activities will be performed outside of the nesting season for birds(February 1—September 15). If trimming or removal of trees during the nesting bird season cannot be avoided, a qualified biologist will monitor tree trimming and removal activities, if nests are found present during the pre-construction survey.
With implementation of MMs BID-1 and BI0-2,the Project would not have a substantial adverse effect, either directly or through habitat modifications,on any species identified as a candidate, sensitive,or special-status species in local or regional plans, policies,or regulations,or by the California Department of Fish and Wildlife (CDFW)or United States Fish and Wildlife Service (USFWS).

b. Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans,policies, regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service?(No Impact) According to the Biological Resources Assessment completed for the Project,there are no riparian habitat areas or other sensitive natural communities present on the Project site. Furthermore, according to CNDDB,there are no recorded observations of natural communities of special concern with potential to occur within the Project site or vicinity.Therefore,the Project would not have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations,or by the CDFW or USFWS.There would be no impact, and no mitigation is required.
c. Would the project have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.)through direct removal,filling, hydrological interruption, or other means?(No impact)
According to the Biological Resources Assessment completed for the Project, no drainage features, ponded areas,wetlands,or riparian habitat subject to jurisdiction of CDFW, United States Army Corps of Engineers (USAGE),and/or Regional Water Quality Control Board (RWQCB)are present within the Project site.As such,implementation of the Project would not adversely affect any State or federally protected wetlands,and no impact would occur. d. Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites?(Less Than Significant with Mitigation Incorporated)
Habitat linkages provide connections between larger habitat areas that are separated by development.Wildlife corridors are similar to linkages but provide specific opportunities for animals to disperse or migrate between areas.A corridor can be defined as a linear landscape feature of sufficient width to allow animal movement between two comparatively undisturbed habitat fragments.Adequate cover is essential for a corridor to function as a wildlife movement area. it is possible for a habitat corridor to be adequate for one species yet still inadequate for others. Wildlife corridors are features that allow for the dispersal, seasonal migration, breeding, and foraging of a variety of wildlife species.Additionally, open space can provide a buffer against both human disturbance and natural fluctuations in resources.
Although there is an undeveloped lot adjacent to the eastern boundary of the Project site,the areas south,west,and north of the Project site are fully developed and provide little to no value to wildlife movement. Furthermore,there are no riparian corridors,creeks,or useful patches of habitat within or connecting the Project site to any identified wildlife corridors or linkages. Because the Project site is surrounded by development and an existing masonry wall,the Project would not substantially limit wildlife movement more than the existing movement limitations in the Project vicinity.
Therefore,the Project would not interfere with the movement of any wildlife species or with established wildlife corridors.

While no active nests or birds displaying nesting behavior were observed during the field investigation,the trees adjacent to and within the Project site have the potential to provide minimal foraging and nesting habitat for year-round and seasonal avian residents,as well as migrating songbirds that could occur in the area that are adapted to urban environments.As such, MM BIO-2 would be required to reduce impacts to nesting birds prior to commencement of construction.
With implementation of MM BIO-2,the Project would not interfere with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors or impede the use of native wildlife nursery sites,and impacts would be less than significant with mitigation incorporated.
e. Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance?(No Impact) The City of Upland Municipal Code Chapter 12.24.100,Tree removal—Permit,2°requires a permit and approval by the City Manager for the removal of any street trees located between the improved vehicular roadway portion of a public street and the abutting property. Up to two of the existing street trees would be removed to accommodate the driveway off East 20th Street.The Project Applicant would be required to request approval from the City for the removal of any street trees and would follow the requirements of Chapter 12.24.100 of the City's Municipal Code.Therefore, the Project would not conflict with any local policies or ordinances protecting biological resources, and no impact would occur.
f Would the project conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan?(No impact)
The Project is not subject to any Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional,or State habitat conservation plan.As a result, no impact would occur.

(1) A resource listed in or determined to be eligible by the State Historical Resources Commission,for listing in the California Register of Historical Resources(California Register) (Pub. Res. Code§5024.1,Title 14 California Code of Regulations[CCR],Section 4850 et seq.).
(2) A resource included in a local register of historical resources, as defined in section 5020.1(k)of the Public Resources Code or identified as significant in an historical resource survey meeting the requirements section 5024.1(g)of the Public Resources Code,shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant.
(3) Any object, building,structure,site,area, place, record, or manuscript which a lead agency determines to be historically significant or significant in the architectural,engineering, scientific, economic,agricultural,educational,social, political, military,or cultural annals of California may be considered to be an historical resource, provided the lead agency's determination is supported by substantial evidence in light of the whole record.Generally,a resource shall be considered by the lead agency to be"historically significant" if the resource 21 LSA.2024d.Cultural Resources Assessment,San Antonio Water Company Headquarters Project, City of Upland,San Bernardino County,California.

meets the criteria for listing on the California Register of Historical Resources (Pub. Res. Code, §5024.1,Title 14 CCR,Section 4852) including the following:
A. Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage.
B. Is associated with the lives of persons important in our past.
C. Embodies the distinctive characteristics of a type, period, region,or method of construction, or represents the work of an important creative individual, or possess high artistic values.
D. Has yielded, or may be likely to yield, information important in prehistory or history.
A"substantial adverse change"to a historical resource,according to PRC Section 5020.1(q),"means demolition,destruction, relocation,or alteration such that the significance of a historical resource would be impaired."
To identify potential historical resources on the Project site,the following tasks were completed: (1) a records search was conducted at the South Central Coastal Information Center(SCCIC)at California State University, Fullerton,on July 11,2024 and the Sacred Lands File(SLF)from the Native American Heritage Commission (NAHC)on July 8, 2024; (2)archival research including, but not limited to, online sources, published literature in local and regional history, news articles, historic aerial photographs, and historic maps was completed during the months of August and September 2024; and (3)field surveys were conducted on the site on July 8,2024, and August 6, 2024.
Data from the records search conducted at the SCCIC indicated there have been 11 cultural resource studies previously conducted within 0.5 mile of the Project site,four of which included portions and the entirety of the Project site.Two cultural resources are documented within/partially within the Project site,and 12 others are recorded within 0.5 mile, all of which consist of built environment.
The only historic-period (50 years of age or older) resource that was identified in the Project site is a mostly subterranean,concrete water reservoir that was built in 1930 as part of the irrigation system for nearby citrus groves.The reservoir's primary purpose now is to provide non-potable water to the nearby Holliday Rock Quarry.The reservoir was evaluated for historical significance using the criteria for listing in the California Register of Historical Resources and designation as a City Cultural Resource. It did not meet any of the State or local criteria and therefore is not considered a historical resource pursuant to Section 15064.5 of the State CEQA Guidelines.
No archaeological resources are documented within a 0.5 mile of the Project site,and none were identified during the archaeological survey. Despite the lack of surface visibility,the parcel has been severely disturbed and the sensitivity for subsurface resources is low.
Although no archaeological deposits have been recorded at the Project site,there is the potential for previously unknown pre-contact archaeological deposits to be unearthed during construction activities.Should Project excavation unearth intact archaeological deposits,a substantial adverse 4-22 P:1,2024\2O241723_San Antonio Driveway Expansion\PRODUCTS\CEQA\Public Review Oraft\5an Antonio Water Headquarters ISMND 48.as25.docx maws)

change to a historical resource would occur due to the partial or complete destruction of the resource.This destruction would undermine the integrity of the resource,such that it would no longer be eligible for listing in the California Register of Historical Resources.As such, Project ground-disturbing activities could have a substantial adverse change on buried archaeological deposits that qualify as historical resources,as defined in State CEQA Guidelines Section 15064.5, and could materially impair pre-contact archaeological deposits. Implementation of Mitigation Measure(MM)CUL-1 would reduce potential impacts to historic archaeological resources to a less than significant level.
MM CUL-1 Unknown Archaeological Resources. In the event that archaeological resources are discovered during excavation,grading,or construction activities,work shall cease within 50 feet of the find until a qualified archaeologist from the San Bernardino County List of Qualified Archaeologists has evaluated the find in accordance with federal,State,and local guidelines to determine whether the find constitutes a "unique archaeological resource,"as defined in Section 21083.2(g) of the California Public Resources Code(PRC). Personnel of the Project shall not collect or move any archaeological materials and associated materials.Construction activity may continue unimpeded on other portions of the Project site.The found deposits shall be treated in accordance with federal,State,and local guidelines, including those set forth in PRC Section 21083.2. Prior to issuance of a grading permit,the Director of Planning Services,or designee, shall ensure that this mitigation measure is documented on the grading plans.
b. Would the project cause a substantial adverse change in the significance of an archaeological resource pursuant to§15064.5?(Less Than Significant with Mitigation Incorporated) In accordance with State CEQA Guidelines Section 15064.5(c)), if the project would affect an archaeological deposit,the lead agency must first determine whether the deposit is a "historical resource" (see CEQA Guidelines Section 15064.5(a)). If the deposit is not a historical resource,the lead agency must determine if the deposit is a "unique archaeological resource." Based on the significance criteria identified above,the Project would have a significant impact on the environment if ground-disturbing activities would cause a substantial adverse change in the significance of a historical or archaeological resource.A substantial adverse change in the significance of an archaeological resource would occur from its demolition,destruction, relocation, or alteration such that the significance of the resource would be materially impaired (CEQA Guidelines Section 15064.5(b)(1)). For the Project,the significance of an archaeological resource would be materially impaired if ground disturbance would alter in an adverse manner those physical characteristics of the resource that convey its historical significance and that justify its eligibility for inclusion in the California Register of Historical Resources.The Project could affect previously unidentified archaeological deposits,thereby causing a substantial adverse change in the significance of an archaeological resource as defined in Section 15064.5. However, potential impacts would be reduced to a less than significant level with implementation of MM CUL-1.

c. Would the project disturb any humans remains, including those interred outside of formal cemeteries?(Less Than Significant with Mitigation incorporated) Although no human remains are known to be on the Project site or are anticipated to be discovered during Project construction,there is always a possibility of encountering unanticipated cultural resources, including human remains,during construction activities. Disturbing human remains could violate the State's Health and Safety Code as well as destroy the resource. In the event that human remains are discovered during construction activities,the Construction Contractor shall implement MM CUL-2,which requires compliance with the State's Health and Safety Code for the treatment of human remains.With implementation of MM CUL-2,the Project would have a less than significant with mitigation incorporated.
MM CUL-2 Human Remains. If human remains are encountered,State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to State Public Resources Code(PRC)Section 5097.98.The County Coroner must be notified of the find immediately. If the remains are determined to be Native American,the County Coroner would notify the Native American Heritage Commission(NAHC),which would determine and notify a Most Likely Descendant(MID).With the permission of the landowner or his/her authorized representative,the MLD may inspect the site of the discovery.The MID shall complete the inspection and make recommendations or preferences for treatment within 48 hours of being granted access to the site.The MID recommendations may include scientific removal and nondestructive analysis of human remains and items associated with Native American burials, preservation of Native American human remains and associated grave goods in place, relinquishment of Native American human remains and associated items to the descendants for treatment,or any other culturally appropriate treatment. Prior to issuance of a grading permit,the Director of Planning Services or designee shall ensure that this mitigation measure is documented on the grading plans.

a. Would the project result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources during project construction or operation?(Less Than Significant Impact)
Construction Energy Use. Construction of the Project is anticipated to begin in 2025 and be completed by the end of 2026.The Project would include site preparation,grading, building construction, paving, and architectural coating activities during construction.
Construction of the Project would require energy for the manufacture and transport of building materials, preparation of the site for grading activities,and building construction. Petroleum fuels (e.g., diesel and gasoline)would be the primary sources of energy for these activities. Energy usage on the Project site during construction would be temporary in nature and would be relatively small in comparison to the State's available energy sources.Additionally,the Project would be subject to the California Air Resources Board's (CARB) In-Use Off-Road Diesel Vehicle Regulation that applies to certain off-road diesel engines,vehicles,or equipment greater than 25 horsepower.The regulation (1) imposes limits on idling, requires a written idling policy,and requires a disclosure when selling vehicles; (2) requires all vehicles to be reported to CARB(using the Diesel Off-Road Online Reporting System) and labeled; (3) restricts the adding of older vehicles into fleets starting on January 1,2014; and (4) requires fleets to reduce their emissions by retiring, replacing,or repowering older engines, or installing Verified Diesel Emission Control Strategies(i.e.,exhaust retrofits).The fleet must either show that its fleet average index was less than or equal to the calculated fleet average target rate, or that the fleet has met the Best Achievable Control Technology requirements.Therefore,impacts to energy resources during construction would be less than significant,and no mitigation is required.
Operational Energy Use.Typically,the consumption of energy during the operation of a project is associated with natural gas use,energy consumption, and fuel used for vehicle trips.The Project would not increase the demand for natural gas as the Project would be designed to be all-electric and would not include the use of any natural gas systems.
Energy consumption was estimated for the Project using default energy intensities by building type in California Emissions Estimator Model (CalEEMod).22 Electricity estimates associated with the 22 ISA.2024b.Traffic impact Analysis San Antonio Water Headquarters Project.November.

Project are shown in Table 4.6.A. In addition,the Project would result in energy usage associated with gasoline and diesel to fuel Project-related vehicle and truck trips. Based on the CalEEMod analysis,the Project would result in approximately 534,492 vehicle miles traveled (VMT) per year.
The average fuel economy for light-duty vehicles(autos, pickups,vans,and SUVs) in the United States has steadily increased from about 14.9 miles per gallon (mpg) in 1980 to 22.9 mpg in 2020.23 Therefore, using these average fuel economy estimates,the Project would result in the consumption of approximately 23,340 gallons of gasoline per year.Table 4.6.A, below, shows the estimated potential increased electricity and gasoline demand associated with operation of the Project.

kWh=kilowatt-hours
As shown in Table 4.6.A,the estimated potential increased electricity demand associated with operation of the Project is 229,785 kilowatt-hours(kWh) per year. In 2022,California's in-State electric generation totaled 203,257 gigawatt-hours(GWh),and the State's total system electric generation,which includes imported electricity,totaled 287,220 GWh.24 Therefore,electricity demand associated with the Project would be approximately 0.0001 percent25 of electricity generated in the State in 2022, which would not represent a substantial demand on available electricity resources. Electrical demand associated with Project operations would be limited to only what is required to efficiently meet the Project's operational needs. In addition,the Project would be designed to the latest mandatory California Green Building Standards Code(CALGreen Code) standards and Title 24 efficiency standards.Additionally,the Project would incorporate sustainability features including a solar cover,which would further reduce the energy demand associated with Project operation.Therefore,the Project's electrical demand would not be considered inefficient,wasteful,or unnecessary.
The Project would also result in energy usage associated with gasoline and diesel to fuel Project- related trips.As shown above in Table 4.6.A,vehicle trips associated with the Project would consume approximately 23,340 gallons of gasoline per year. California is expected to consume approximately 18.5 billion gallons of petroleum per year by 2024 and countywide total petroleum 23 United States Department of Transportation(USDOT)."Table 4-23:Average Fuel Efficiency of U.S. Light Duty Vehicles."Website: https://www.bts.gov/content/average-fuel-efficiency-us-light-duty-vehicles (accessed September 4,2024).

use by vehicles is expected to be 1.221 billion gallons per year by 2024.26 Therefore,the Project would represent approximately 0.002 percent27 of the County's anticipated petroleum usage in 2024.Therefore,gasoline and diesel demand generated by vehicle and truck trips associated with the Project would be a minimal fraction of gasoline and diesel fuel consumption in California.
Therefore, implementation of the Project would not result in a substantial increase in electricity, natural gas,or transportation-related energy,such that it would result in a wasteful,inefficient, or unnecessary consumption of energy resources. Impacts would be less than significant,and no mitigation is required.
b. Conflict with or obstruct a state or local plan for renewable energy or energy efficiency?(Less Than Significant impact)
Less Than Significant Impact. In 2002,the Legislature passed Senate Bill (SB) 1389,which required the California Energy Commission (CEC)to develop an integrated energy plan every 2 years for electricity, natural gas, and transportation fuels for the Integrated Energy Policy Report.The plan calls for the State to assist in the transformation of the transportation system to improve air quality, reduce congestion,and increase the efficient use of fuel supplies with the least environmental and energy costs.To further this policy,the plan identifies a number of strategies, including assistance to public agencies and fleet operators in implementing incentive programs for Zero-Emission Vehicles (ZEVs)and their infrastructure needs,and encouragement of urban designs that reduce VMT and accommodate pedestrian and bicycle access.
The CEC's 2023 Integrated Energy Policy Report provides the results of the CEC's assessments of a variety of energy issues facing California.As indicated above,energy usage on the Project site during construction would be temporary in nature and would be relatively small in comparison to the overall use in the State. In addition,energy usage associated with operation of the Project would be relatively small in comparison to the overall use of the State's available energy resources.Therefore, energy impacts at the regional level would be negligible. Because California's energy conservation planning actions are conducted at a regional level,and because the Project's total impact on regional energy supplies would be minor,the Project would not conflict with or obstruct California's energy conservation plans as described in the CEC's Integrated Energy Policy Report. Additionally, as demonstrated above,the Project would not result in the inefficient,wasteful,and unnecessary consumption of energy. Potential impacts related to conflict with or obstruction of a State or local plan for renewable energy or energy efficiency would be less than significant,and no mitigation is required.

Zones delineate areas around active faults with potential surface fault rupture hazards that would require specific geological investigations prior to approval of certain kinds of development within the delineated area.There are no mapped faults within or adjacent to the Project site,and the Project site is not located within an Alquist-Priolo Zone.2s The nearest mapped fault to the Project site is the Cucamonga Fault,which is located approximately 1.3 miles north of the Project site.
Therefore,the Project would not directly or indirectly cause substantial adverse effects related to fault rupture,and there would be no impact.
ii. Strong seismic ground shaking?(No Impact)
The Project site is in a seismically active area,where earthquakes have the potential to subject the Project to strong seismic ground shaking.The intensity of ground shaking would depend on the characteristics of the fault,distance from the fault,the earthquake magnitude and duration,and site-specific geologic conditions.
The City requires projects to comply with the 2022 California Building Code (CBC) (Title 24,California Code of Regulations),30 which provides for stringent construction requirements on projects in areas of high seismic risk based on numerous inter-related factors. It is acknowledged that seismic hazards cannot be completely eliminated, even with implementation of advanced building practices.
However,the seismic design standards of the CBC are intended to prevent catastrophic structural failure in the most severe earthquakes currently anticipated.Therefore,the Project would not directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury, or death involving seismic ground shaking and there would be no impact. iii. Seismic-related ground failure, including liquefaction?(Na Impact) Liquefaction.Soil liquefaction is a phenomenon primarily associated with saturated soil layers located close to the ground surface. During ground shaking,these soils lose strength and acquire "mobility" sufficient to permit both horizontal and vertical movements.The significant factors on which liquefaction potential of a soil deposit depends,among others include,soil type, relative soil density, intensity of earthquake,duration of ground shaking,and depth of ground water.Soils that are most susceptible to liquefaction are clean, loose, uniformly graded, saturated,fine-grained sands that lie relatively close to the ground surface. However, loose sands that contain a significant amount of fines(i.e., silt and clay) may also liquefy.As detailed in the Report of Geotechnical Evaluations31 completed for the Project, no groundwater was encountered within the depth of 3 feet explored and available recorded groundwater well data in the Project vicinity indicates historical groundwater measured at approximately 267 feet below ground. Based on the Special Publication 117, published by the State of California Department of Conservation, Division of Mines and Geology, soils are non-susceptible to seismically induced soils in the absence of groundwater 29 California Department of Conservation (DOC)California Geologic Survey(CGS).2021.Earthquake Zones of Required Investigation.Website: https://maps.conservation.ca.gov/cgs/EQZApp/app/(accessed July 2, 2024).

within 50 feet below grade.Therefore,the Project site would not be susceptible to liquefaction and no impact would occur.
Lateral Spreading. Lateral spreading is a form of horizontal displacement of soil toward an open channel or other"free"face,such as an excavation boundary. In a lateral spread failure, a layer of ground at the surface is carried on an underlying layer of liquefied material over a nearly flat surface toward a river channel or other bank.The lateral spreading hazard tends to mirror the liquefaction hazard for a site. Because the topography of the site is near level and the Project site is not susceptible to liquefaction,the potential for seismically induced lateral spreading is low.Therefore, the Project site would not be susceptible to lateral spreading and no impact would occur. iv. Landslides?(Na Impact)
A landslide generally occurs on relatively steep slopes and/or on slopes underlain by weak materials.
The Project site is relatively level and is not located next to any slopes.The only area within Upland that has been identified as susceptible to slope stability hazards is San Antonio Heights,which is located approximately 0.75 mile north of the Project site and contains slopes that vary between 15 and 20 percent.32 Therefore,the Project would not directly or indirectly cause potential substantial adverse effects,including the risk of loss, injury,or death involving landslides and there would be no impact.
b. Would the project result in substantial soil erosion or the loss of topsoil?(Less Than Significant Impact)
Topsoil is defined as the upper part of the soil profile that is relatively rich in humus and is technically known as the A-horizon of the soil profile.33 Grading and earthmoving during Project construction has the potential to result in erosion and loss of topsoil. Exposed soils could be entrained in stormwater runoff and transported off the Project site. However,this impact would be reduced to a less than significant level through compliance with the preparation and implementation of a Stormwater Pollution Prevention Plan (SWPPP), as detailed in Section 4.10, Hydrology and Water Quality.Although designed primarily to protect stormwater quality,the SWPPP would incorporate Best Management Practices(BMPs)to minimize impacts related to erosion to a less than significant level.
c. Would the project be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on-or off-site landslide, lateral spreading,subsidence,liquefaction or collapse?(Less Than Significant impact) 32 City of Upland.2015b.Final Program Environmental Impact Report General Plan Update(GPU 08-03), Zoning Code Update(ZCU 08-03), Climate Action Plan,and Cable Airport Land Use Compatibility Plan Update 5CH No.2012041006).September 28.

As discussed in Section 4.7.a,site soils would not be subject to landslides, liquefaction,or lateral spreading.
Subsidence.Subsidence can result from the removal of subsurface water resulting in either gradual depression or catastrophic collapse of the ground surface.As detailed in the Report of Geotechnical Evaluations completed for the Project,no groundwater was encountered within the 3-foot depth explored,and available recorded groundwater well data in the Project vicinity indicate historical groundwater measured at approximately 267 feet below ground.The Project would require excavation to a maximum depth of 6 feet below ground surface.Therefore, it is not anticipated that dewatering or shoring of groundwater would be required during construction.Subsidence would not occur, and there would be no impact.
Unstable Soils and Collapse.As detailed in the Report of Geotechnical Evaluations completed for the Project, upper soils on the Project site are generally,dry,silty,and gravelly,with variable consistency. For adequate structural support,the Report of Geotechnical Evaluations recommends the reworking of load bearing soils in the form of sub excavations,followed by scarification, moisturization,and replacement with engineered fills compacted to minimum 90 percent.
Additionally,to minimize potential for differential settlements,the Report of Geotechnical Evaluations recommends that structural footings be established exclusively into engineered fills of local soils,compacted as recommended in the Report of Geotechnical Evaluations.With implementation of the recommendations included in the Report of Geotechnical Evaluations and requirements of the CBC, impacts related to unstable soils and collapse would be less than significant. No mitigation is required.
d. Would the project be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code(1994), creating substantial direct or indirect risks to life or property?(No Impact) Expansive soils are characterized by the potential for shrinking and swelling as the moisture content of the soil decreases and increases, respectively.Shrink-swell potential is influenced by the amount and type of clay minerals present and can be measured by the percent change of the soil volume.As detailed in the Report of Geotechnical Evaluations completed for the Project,soils on-site consist of fine to medium coarse to coarse sands with traces of silts along with rocks and cobbles,which are considered low in expansion potential.Therefore,the Project would not be located on expansive soil,creating substantial direct or indirect risks to life or property,and there would be no impact. e. Would the project have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water?(No Impact)
Development of the Project would not involve the use of septic tanks or alternative wastewater disposal systems.Therefore,the Project would have no impact related to septic tanks or alternative wastewater disposal systems.

f Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?(Less Than Significant with Mitigation incorporated) There are no known paleontological resources or unique geologic features within or near the Project site.The City of Upland lies upon a thin blanket of alluvial sediments derived from southbound erosion of the San Bernardino Mountains. Most of these sediments were deposited during the Holocene era (to 10,000 years before the present),and most paleontologists consider Holocene alluvial sediments too young to contain fossils. Deep excavations may expose strata associated with late Pleistocene(10,000 to 120,000 years ago)alluvial deposition. Depending upon its lithology, Pleistocene strata have moderate potential for paleontological resources.34 Therefore,the possibility of accidental discovery of paleontological resources during Project construction cannot be discounted. Implementation of Mitigation Measure(MM)GEO-1, described below,would reduce potential impacts to paleontological resources to a less than significant level.
MM GEO-1 Paleontological Resources Impact Mitigation Program.Should paleontological resources be encountered during Project subsurface construction activities, all ground-disturbing activities within 25 feet shall be redirected and a qualified paleontologist contacted to assess the situation,consult with agencies as appropriate,and make recommendations for the treatment of the discovery. For purposes of this mitigation,a "qualified paleontologist"shall be an individual with the following qualifications: (1)a graduate degree in paleontology or geology and/or a person with a demonstrated publication record in peer-reviewed paleontological journals; (2) at least two years of professional experience related to paleontology; (3) proficiency in recognizing fossils in the field and determining their significance; (4) expertise in local geology,stratigraphy,and biostratigraphy;and (5) experience collecting vertebrate fossils in the field. If the paleontological resources are found to be significant and Project activities cannot avoid them, measures shall be implemented to ensure that the Project does not cause a substantial adverse change in the significance of the paleontological resource. Measures may include monitoring, recording the fossil locality,data recovery and analysis,a final report, and accessioning the fossil material and technical report to a paleontological repository. Upon completion of the assessment,a report documenting methods, findings,and recommendations shall be prepared and submitted to the City of Upland for review. If paleontological materials are recovered,this report also shall be submitted to a paleontological repository such as the University of California Museum of Paleontology,along with significant paleontological materials. Public educational outreach may also be appropriate.

Would the project:
a) Generate greenhouse gas emissions,either directly or indirectly,that may have a significant impact on the ❑ ❑ ® ❑ environment?
b) Conflict with an applicable plan,policy or regulation adopted for the purpose of reducing the emissions of greenhouse ❑ ❑ ® ❑ gases?
The following discussion and analyses are based on the findings included in the Air Quality and Greenhouse Gas Technical Memorandum3s completed for the Project,which is included as Appendix A to this IS/MND.
a. Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?(Less Than Significant impact) This section describes the Project's construction-and operation-related greenhouse gas(GHG) emissions and contribution to global climate change.The South Coast Air Quality Management District(SCAQMD) has not addressed emission thresholds for construction in its CEQA Air Quality Handbook; however,SCAQMD requires quantification and disclosure.Thus,this section discusses construction emissions.
Construction Greenhouse Gas Emissions.Construction activities associated with the Project would produce combustion emissions from various sources.Construction would emit GHGs through the operation of construction equipment and from worker and builder supply vendor vehicles for the duration of the approximately 15-month construction period.The combustion of fossil-based fuels creates GHGs such as carbon dioxide(CO2), methane(CH4),and nitrous oxide(N20). Furthermore, the fueling of heavy equipment emits CH4. Exhaust emissions from on-site construction activities would vary daily as construction activity levels change.
As indicated above,SCAQMD does not have an adopted threshold of significance for construction- related GHG emissions. However, lead agencies are required to quantify and disclose GHG emissions that would occur during construction.The SCAQMD then requires the construction GHG emissions to be amortized over the life of the project(which is defined as 30 years), added to the operational emissions,and compared to the applicable interim GHG significance threshold tier. Based on California Emissions Estimator Model (CalEEMod),it is estimated that the Project would generate 395 metric tons of carbon dioxide equivalent(MT CO2e)during construction of the Project.When amortized over the 30-year life of the Project,annual emissions would be 13 MT CO2e. 35 LSA.2024a.Air Quality and Greenhouse Gas Technical Memorandum for the Proposed San Antonio Water Headquarters in Upland, California(LSA Project No.2024I723).

Operational Greenhouse Gas Emissions. Long-term GHG emissions are typically generated from mobile sources(e.g.,cars,trucks,and buses), area sources(e.g., maintenance activities and landscaping), indirect emissions from sources associated with energy consumption,and refrigerant fugitive emissions.
GHG emissions were estimated using CalEEMod.Table 4.8.A shows the estimated operational GHG emissions for the Project. Motor vehicle emissions are the largest source of GHG emissions for the Project, at approximately 49 percent of the Project total. Refrigerant sources are the next largest category, at approximately 35 percent. Energy,water, and waste sources represent approximately 14 percent, 1 percent,and 2 percent of the total emissions, respectively. Area sources make up less than 1 percent of the total emissions.

CO2e=carbon dioxide equivalent SCAQMD=South Coast Air Quality Management District As discussed above, a project would have less than significant GHG emissions if it would result in operational-related GHG emissions of less than 3,000 MT CO2e per year. Based on the analysis results,the Project would result in approximately 412 MT CO2e per year,which would not exceed the SCAQMD threshold of 3,000 MT CO2e per year.Therefore, Project-level and cumulative GHG emissions would be less than significant,and operation of the Project would not generate GHG emissions that would have a significant effect on the environment. Impacts would be less than significant, and no mitigation is required.
b. Would the project conflict with an applicable plan,policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?(Less Than Significant impact) The following discussion evaluates the Project according to the goals of the 2022 Scoping Plan and Southern California Association of Governments' (SLAG)2020-2045 Regional Transportation Plan/Sustainable Communities Strategy(RTP/SCS).

2022 Scoping Plan. Executive Order(EO) B-30-15 added the immediate target of reducing GHG emissions to 40 percent below 1990 levels by 2030.Senate Bill (SB)32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reduction target of at least 40 percent below 1990 levels by 2030 contained in EO B-30-15.CARB released the 2017 Scoping Plan to reflect the 2030 target set by EO B-30-15 and codified by SB 32.36 SB 32 builds on Assembly Bill (AB)32 and keeps California on the path toward achieving the State's 2050 objective of reducing emissions to 80 percent below 1990 levels.AB 197,the companion bill to SB 32, provides additional direction to CARB that is related to the adoption of strategies to reduce GHG emissions.Additional direction in AB 197 that is intended to provide easier public access to air emission data collected by CARB was posted in December 2016.AB 1279 codifies the State goals of achieving net carbon neutrality by 2045 and maintaining net negative GHG emissions thereafter.
In addition,the 2022 Scoping PIan37 assesses progress toward the statutory 2030 target while laying out a path to achieving carbon neutrality no later than 2045.The 2022 Scoping Plan focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology,energy deployment, natural and working lands, and others, and is designed to meet the State's long-term climate objectives and support a range of economic,environmental,energy security,environmental justice, and public health priorities.
The 2022 Scoping Plan focuses on building clean energy production and distribution infrastructure for a carbon-neutral future, including transitioning existing energy production and transmission infrastructure to produce zero-carbon electricity and hydrogen, and utilizing biogas resulting from wildfire management or landfill and dairy operations,among other substitutes.The 2022 Scoping Plan states that in almost all sectors,electrification will play an important role.The 2022 Scoping Plan evaluates clean energy and technology options and the transition away from fossil fuels, including adding four times the solar and wind capacity by 2045 and about 1,700 times the amount of current hydrogen supply.As discussed in the 2022 Scoping Plan, EO N-79-20 requires that all new passenger vehicles sold in California be zero-emission by 2035 and that all other fleets transition to zero-emission as fully as possible by 2045,which will reduce the percentage of fossil fuel combustion vehicles.
• Energy-efficient measures are intended to maximize energy efficiency building and appliance standards, pursue additional efficiency efforts including new technologies and new policy and implementation mechanisms,and pursue comparable investment in energy efficiency from all retail providers of electricity in California. In addition,these measures are designed to expand the use of green building practices to reduce the carbon footprint of California's new and existing inventory of buildings.The Project would develop an existing undeveloped portion of SAWCo land into new SAWCo headquarters.As mentioned above,the Project would not be powered by natural gas,and no natural gas would be used during construction or operation of the Project.The elimination of natural gas in new development would help projects implement their"fair share"of achieving long-term 2045 carbon neutrality consistent with State goals.As such, if a project does not use natural gas, a lead agency can conclude that it would be 36 CARB.2022.2022 Scoping Plan for Achieving Carbon Neutrality.

consistent with achieving the 2045 neutrality goal and will not have a cumulative considerable impact on climate change.The Project does not include natural gas. In addition,the Project would comply with the latest Title 24 standards regarding energy conservation and green building standards.Therefore,the Project would comply with applicable energy measures. • Water conservation and efficiency measures are intended to continue efficiency programs and use cleaner energy sources to move and treat water. Increasing the efficiency of water transport and reducing water use would reduce GHG emissions.As noted above,the Project would be required to comply with the latest Title 24 standards,which include a variety of different measures, including reduction of wastewater and water use.The Project would also include low water landscape in their design. In addition,the Project would be required to comply with the California Model Water Efficient Landscape Ordinance.Therefore,the Project would not conflict with any of the water conservation and efficiency measures. • The goal of transportation and motor vehicle measures is to develop regional GHG emissions reduction targets for passenger vehicles.Specific regional emission targets for transportation emissions would not directly apply to the Project. However,vehicles traveling to the Project site would comply with the Pavley II (LEV Ill)Advanced Clean Cars Program.The second phase of Pavley standards reduces GHG emissions from new cars by 34 percent from 2016 levels by 2025, resulted in a 3 percent decrease in average vehicle emissions for all vehicles as of 2020.
Therefore,the Project would not conflict with the identified transportation and motor vehicle measures.
The Project would comply with existing State regulations adopted to achieve the overall GHG emission reduction goals identified in the 2022 Scoping Plan, EO B-30-15,SB 32,AB 197,and AB 1279.
SCAG's Regional Transportation Plan/Sustainable Communities Strategy.SCAG's 2024-2050 RTP/SC538 identifies land use strategies that focus on new housing and job growth in areas served by high-quality transit,and other opportunity areas would be consistent with a land use development pattern that supports and complements the proposed transportation network.The core vision in the 2024-2050 RTP/SCS is to better manage the existing transportation system through design management strategies, integrate land use decisions and technological advancements, create complete streets that are safe for all roadway users, preserve the transportation system, and expand transit and foster development in transit-oriented communities.The 2024-2050 RTP/SCS contains transportation projects to help more efficiently distribute population, housing,and employment growth, as well as providing a forecast development pattern that is generally consistent with regional-level General Plan data.The forecast development pattern,when integrated with the financially constrained transportation investments identified in the 2024-2050 RTP/SCS,would reach the regional target of reducing GHG emissions from automobiles and light- duty trucks by 8 percent by 2020 and 19 percent by 2035 (compared to 2005 levels per capita 98 Southern California Association of Governments(SCAG).2020.Connect SoCal:The 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy of the Southern California Association of Governments.Website:scag.ca.gov/sites/main/files/file-attachments/0903fconnectsocal-plan_0. pdf?1605001176(accessed November 2024).

emission levels).The 2024-2050 RTP/SCS does not require that local General Plans,Specific Plans,or zoning be consistent with the 2024-2050 RTP/SCS, but it provides incentives for consistency for governments and developers.
Implementing SCAG's RTP/SCS will greatly reduce the regional GHG emissions from transportation, helping to achieve statewide emissions reduction targets.As demonstrated in Section 4.3.1 of the Air Quality section,the Project does not meet the criteria identified in State CEQA Guidelines Section 15205.b.2(Projects of Statewide, Regional, or Areawide Significance)for projects of statewide, regional,or areawide significance. In addition,while the Project would require a change to the General Plan land use designation and the current zoning,the City of Upland plans to update both the General Plan and zoning to accommodate the Project. As demonstrated in Table 4.8.A,the Project would not generate significant levels of GHGs,thus would not interfere with SCAG's ability to achieve the region's GHG reduction target of 19 percent below 2005 per capita emissions levels by 2035. Furthermore,the Project is not regionally significant per State CEQA Guidelines Section 15206, and,as such, it would not conflict with the SCAG RTP/SCS targets since those targets were established and are applicable on a regional level. Impacts would be less than significant,and no mitigation is required.

Hazardous materials that are currently stored on the site in reportable quantities include diesel fuel in quantities of 120 to 599 gallons.39 Operation of the Project involves routine transport, use, and/or disposal of hazardous materials. Hazardous materials (e.g.,oil,grease,fuels, paint)would be transported and used on-site during construction activities.The routine transport, use,or disposal of these hazardous materials could pose a potential hazard to construction workers and future employees working at the Project site as they would be handling the hazardous materials and could therefore be exposed through inhalation of vapors,direct contact with skin,or accidental ingestion.The routine transport, use,or disposal of these hazardous materials would not pose a significant hazard to the public or 39 California Department of Toxic Substances Control(DTSC).2021.Facilities from the California Environmental Reporting Systems(CERS).Website: https://siteportal.calepa.ca.gov/nsite/site/427484 (accessed July 2,2024).

environment unless the hazardous materials were accidentally spilled or released into the environment, as discussed in Section 4.9.b below.
The Project site would be subject to existing regulatory programs for hazardous materials.The San Bernardino County Fire Protection District(SBCFPD) Hazardous Materials Division is designated as the Certified Unified Program Agency(CUPA)for the City of Upland,and coordinates the regulation of hazardous materials and hazardous wastes in the City of Upland through the following programs; • Hazardous Materials Business Plan
• Hazardous Waste&Onsite Treatment
• Aboveground Petroleum Storage Act(APSA)
• Underground Storage Tank(UST) Program
• California Accidental Release Program (CalARP)
• Uniform Fire Code Hazardous Material Management Plans and Inventories The role of a CUPA is to consolidate,coordinate,and make consistent the administrative requirements, permits, inspections, and enforcement activities associated with the regulation of hazardous materials and hazardous wastes. Businesses that store or use hazardous materials in the City limits of Upland are required to submit chemical and facility information on the California Environmental Reporting Systems(CERS),which is a statewide web-based system to support CUPAs in electronically collecting and reporting various hazardous materials-related data as mandated by the California Health and Safety Code and 2008 legislation(Assembly Bill [AB] 2286).Chapter 6.95 of Division 20 of the California Health and Safety Code requires that an Hazardous Materials Business Plan (HMBP)must be submitted to the local CUPA if on-site hazardous materials exceed in aggregate any of the following: 55 gallons for liquids;500 pounds for solids; or 200 cubic feet of gases at standard temperature and pressure. HMBPs are required to be submitted electronically to the CERS and must include facility information, a Hazardous Materials Inventory Statement,an Emergency Response Plan,and an Emergency Response Training Plan.The HMBP has to be re- certified for completeness and accuracy every year,or updated and revised,as necessary.
Worker health and safety is regulated at the federal level by the United States Department of Labor, Occupational Safety and Health Administration (OSHA). OSHA regulations include training requirements for construction workers and a requirement that hazardous materials are accompanied by manufacturer's Safety Data Sheets(SDSs).The Federal Occupational Safety and Health Act of 1970 authorizes states to establish their own safety and health programs with OSHA approval.Worker health and safety protections in California are regulated by the California Department of Industrial Relations(DIR).The DIR includes the Division of Occupational Safety and Health(DOSH),which acts to protect workers from safety hazards through its California OSHA (Cal/OSHA) program.Cal/OSHA regulations include requirements for protective clothing,training, and limits on exposure to hazardous materials. California standards for workers dealing with hazardous materials are contained in California Code of Regulations(CCR)Title 8 and include practices for all industries(General Industrial Safety Orders),and specific practices for construction, and other industries.The routine transport, use,and disposal of hazardous materials at the Project site during operation and construction activities would be required to comply with a Project Health and Safety Plan(HASP) prepared in accordance with CCR Title 8,which would mitigate potential P:12024\2O241723 SanAntonia Driveway Expansion\PRODUCTS\CEOA Publit ReviewDraft\5an Antonio Water Headquarters ISMND_4A.D8.25.decx(CRIU2/25) 4-39

health hazards for workers related to the routine transport, use,or disposal of hazardous materials to a less than significant level.
As detailed in Section 4.10, Hydrology and Water Quality, because the Project would result in soil disturbance greater than 1 acre, management of hazardous materials during construction activities would be subject to the requirements of the Stormwater Construction General Permit(CGP),which requires preparation and implementation of a Stormwater Pollution Prevention Plan (SWPPP)that includes hazardous materials storage requirements. For example,construction site operators must store chemicals in watertight containers(with appropriate secondary containment to prevent any spillage or leakage)or in a storage shed (completely enclosed).
The transportation of hazardous materials is subject to United States Department of Transportation (USDOT), Resource Conservation and Recovery Act(RCRA), and State regulations. In 1990 and 1994, the federal Hazardous Material Transportation Act was amended to improve the protection of life, property,and the environment from the inherent risks of transporting hazardous material in all major modes of commerce.The USDOT developed hazardous materials regulations,which govern the classification, packaging,communication,transportation, and handling of hazardous materials, as well as employee training and incident reporting.The California Highway Patrol,the California Department of Transportation (Caltrans), and the California Environmental Protection Agency (Cal/EPA) Department of Toxic Substances Control (DISC)are responsible for enforcing federal and State regulations pertaining to the transportation of hazardous materials.
Construction of the Project would result in the generation of various waste materials that would require recycling and/or disposal, including some waste materials that may be classified as hazardous waste. Hazardous wastes would be required to be transported by a licensed hazardous waste hauler and disposed of at facilities that are permitted to accept such materials as required by USDOT, RCRA, and State regulations.
Compliance with the existing hazardous materials regulations and programs described above, including requirements for HMBPs and Risk Management Plans(RMPs)for facilities handling significant quantities of hazardous materials, OSHA and Cal/OSHA regulations,CCR Title 8;the CGP; and USDOT, RCRA, and State regulations,would ensure that the Project would not create a significant hazard to the public or the environment associated with the routine transport, use,or disposal of hazardous materials by ensuring that these materials are properly handled during construction and operation of the Project and therefore,would be considered less than significant. b. Would the project create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment?(Less Than Significant Impact) There are two main ways that the public and/or the environment could be affected by the release of hazardous materials from the Project site, including: (1)exposing workers and/or the public to potentially contaminated soil and groundwater during construction and/or operation of the Project; or(2) exposing workers and/or the public to hazardous building materials(e.g., lead paint,asbestos) during demolition of existing structures.

As described above,diesel fuel in quantities of 120 to 599 gallons and small quantities of other common hazardous materials would be used at the Project site during construction and operation of the Project. Improper use,storage,or handling could result in a release of hazardous materials into the environment which could pose a risk to construction workers and the public. However,the Project Applicant would be required to comply with existing government regulations related to the use and disposal of these materials as detailed previously in Section 4.9.a,and such materials would not be used in sufficient strength or quantity to create a substantial risk to human or environmental health.
The Project would not involve the demolition of any existing structures.The portion of the Project site proposed for development is primarily vacant land that is surrounded by a mix of residential, commercial,and industrial uses.According to the State Water Board's GeoTracker database,there are no documented past releases of hazardous materials in the nearby vicinity of the Project site.4° Based on the observed uses of the properties located immediately adjoining the Project site, it is unlikely that the soil and groundwater are contaminated with significant toxic or hazardous materials that would be released during construction.Additionally,compliance with the regulations described previously in Section 4.9.a would ensure that the Project would not create a significant hazard to the public or the environment through accident conditions involving the release of hazardous materials into the environment during the transport, use,or disposal of hazardous materials by ensuring that these materials are properly handled during construction of the Project.
Therefore,this impact would be less than significant.
c. Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials,substances, or waste within one-quarter mile of an existing or proposed school?(No Impact)
There are no existing or proposed schools within 0.25 mile of the Project site.The closest school to the Project site is the Grace Lutheran Preschool, located approximately 0.35 mile northwest of the Project site. Additionally, as noted in Section 4.9.a,development of the Project would not create a significant hazard to the public or the environment through the routine transport, use,or disposal of hazardous materials and, as noted in Section 4.9.b,construction activities would not create a hazard to the public and environment through reasonably foreseeable upset and accident conditions.
Therefore,there would be no impact.
d. Would the project 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?(No Impact) The Project site is not included on any list of hazardous materials site compiled pursuant to Government Code Section 65962.5,41 and no impact would occur. 40 State Water Resources Control Board(SWRCB).2024.GeoTracker.

e. Would the project be located within an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area?(No Impact) The Project site is located approximately 2.2 miles northeast of the Cable Airport and is not located within the airport's Land Use Compatibility Plan.42 As such, implementation of the Project would not result in a safety hazard or excessive noise for people residing or working in the Project area in association with airports. No impact would occur.
f. Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan?(Less Than Significant Impact) The improvements that would occur as part of the Project are site-specific and do not include any public right-of-way improvements to off-site areas(e.g., roadway improvements, intersection improvements).The Project would not reduce the number of traffic lanes on any adjacent streets and would not alter the existing street grid, and;therefore, it would not alter or obstruct emergency evacuation routes or response plan. The Project site would be accessible to emergency vehicles in the event a hazardous event occurs on the site.Overall,the Project does not include any features that would impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan;therefore,this impact would be less than significant. g. Would the project expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires?(No Impact) The Project site is located in an urban area and is not within or adjacent to a wildland fire hazard area or high fire hazard severity zone.43 Therefore,the Project would not expose people or structures to a significant loss, injury, or death involving wildland fires,and there would be no impact.

The following discussion and analyses are based on the findings included in Preliminary Water Quality Management Plan44 completed for the Project,which is included as Appendix E to this IS!MND.
a. Would the project violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality?(Less Than Significant Impact) The State Water Resources Control Board (SWRCB) and nine Regional Water Quality Control Boards (RWQCBs) regulate the quality of surface water and groundwater bodies throughout California. In Upland,the Santa Ana RWQCB(SARWQCB) is responsible for implementation of the Water Quality Control Plan (Basin Plan).The Basin Plan establishes beneficial water uses and water quality objectives for waterways and water bodies within the region. Section 303(d) of the federal Clean Water Act(CWA) requires that states identify water bodies, including bays, rivers,streams, creeks, and coastal areas,that do not meet water quality standards and the pollutants that are causing the impairment.Total Maximum Daily Loads(TMDLs)describe the maximum amount of a pollutant that °A Land Development Design Company, LLC.2024.Preliminary Water Quality Management Plan For:San Antonio Water Company.September 7.

a water body can receive while still meeting established water quality standards.A TMDL establishes limits for pollutant discharges into impaired water bodies.
As discussed in Chapter 2.0, Project Description,the Project site is undeveloped and does not contain any existing stormwater infrastructure.Stormwater flows to the southwest to a natural ravine which discharges into an existing ditch along the freeway right-of-way which discharges to a City of Fontana storm drain along Poplar Avenue. Receiving waters include the San Sevaine Channel, which flows to the Santa Ana River Reach 3,which drains to the Prado Dam. Prado Dam drains to Santa Ana River Reach 2,which flows to Santa Ana River Reach 1,which discharges to the Pacific Ocean.The receiving waters for stormwater runoff from the Project site are listed as impaired on the 303(d) list for several constituents.4s The San Seavine Channel does not have any listed impairments.The Santa Ana River Reach 3 is listed as an impaired water body for the following pollutants: copper, indicator bacteria,and lead. Prado Basin is listed as impaired for pH,and Santa Ana River Reach 2 and Santa Ana River Reach 1 do not have any listed impairments.
Runoff water quality is regulated by the National Pollutant Discharge Elimination System (NPDES) Program(established through the federal CWA).The NPDES program objective is to control and reduce pollutant discharges to surface water bodies. Compliance with NPDES permits is mandated by State and federal statutes and regulations. Locally,the NPDES Program is administered by the SARWQCB.Construction activities are subject to the SWRCB NPDES General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities,Order No. 2022-0057- DWQ NPDES No. CAS000002(Construction General Permit[CGP]).Any construction activity, including grading,that would result in the disturbance of 1 acre or more would require compliance with SWRCB's CGP,which requires preparation of a SWPPP and implementation of Construction Best Management Practices(BMPs) during construction activities. Construction BMPs would include, but not be limited to, Erosion Control and Sediment Control BMPs designed to minimize erosion and retain sediment on site as well as Good Housekeeping BMPs to prevent spills, leaks,and discharge of construction debris and waste into receiving waters.
Project operations are subject to the NPDES Permit and Waste Discharge Requirements for the San Bernardino County Flood Control District,the County of San Bernardino,and the incorporated Cities of San Bernardino County within the Santa Ana Region, Order No. R8-2010-0036, NPDES No.
CAS618036(MS4 Permit).Any"Significant Redevelopment" projects that add or replace 5,000 square feet or more of impervious surface on an already developed site or"New Development" projects that create 10,000 square feet or more of impervious surface must comply with the requirements of the MS4 Permit.The MS4 permit prohibits discharges,sets limits on pollutants being discharged into receiving waters, and requires implementation of technology-based standards.The MS4 Permit requires co-permittees to develop and implement standard design and post-development BMP guidance to guide application of Low Impact Development(LID) BMPs to the maximum extent practicable.The MS4 Permit requires that a Final Water Quality Management Plan (WQMP) be prepared for new development and significant redevelopment projects within its 45 State Water Resources Control Board(SWRCB).2023.2020-2022 California Integrated Report(Clean Water Act Section 303(d)List and 305(b)Report).Website: https://www.waterboards.ca.gov/water_ issues/progra ms/water quality_assessment/2020_2022_integrated_report.html(accessed September 17, 2024).

jurisdiction. In addition,the NPDES permit includes hydromodification requirements that projects must include management techniques to reduce the potential for impacts, such as a change in runoff and sediment yield because of land use modifications.To address hydromodification requirements with the County of San Bernardino,the Santa Ana RWQCB developed a Technical Guidance Document for Water Quality Management Plans.46 The Final WQMP would specify the Site Design,Source Control, LID,and Treatment Control BMPs that would be implemented to capture,treat,and reduce pollutants of concern in storm water runoff. Design BMPs are storm water management strategies that emphasize conservation and use of existing site features to reduce the amount of runoff and pollutant loading generated from a site.
Source Control BMPs are preventative measures that are implemented to prevent the introduction of pollutants into storm water. LID BMPs mimic a project site's natural hydrology by using design measures that capture,filter,store,evaporate,detain,and infiltrate runoff rather than allowing runoff to flow directly to piped or impervious storm drains.Treatment Control BMPs are structural BMPs designed to treat and reduce pollutants in storm water runoff prior to releasing it to receiving waters.
Construction.The Project involves the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking,solar cover, landscaping,and utility improvements.
Construction activities would result in the disturbance of 2.8 acres of soil. Pollutants of concern during construction include sediments,trash, petroleum products,concrete waste(dry and wet), sanitary waste,and chemicals. Each of these pollutants on its own or in combination with other pollutants can have a detrimental effect on water quality. During construction activities, excavated soil would be exposed,and there would be an increased potential for soil erosion and sedimentation compared to existing conditions. In addition, chemicals, liquid products, petroleum products(e.g., paints,solvents, and fuels), and concrete-related waste may be spilled or leaked, and they have the potential to be transported via storm water runoff into receiving waters.
Because construction of the Project would disturb greater than 1 acre of soil,the Project is subject to the requirements of the CGP,which requires preparation of an SWPPP and implementation of construction BMPs during construction activities. Construction BMPs would include, but are not limited to, Erosion Control and Sediment Control BMPs designed to minimize erosion and retain sediment on site as well as Good Housekeeping BMPs to prevent spills, leaks, and discharge of construction debris and waste into receiving waters.
As detailed in the Report of Geotechnical EvaluationsA7 completed for the Project, no groundwater was encountered within the depth of 3 feet explored and available recorded groundwater well data in the Project vicinity indicates historical groundwater measured at approximately 267 feet below ground.The Project would require excavation to a maximum depth of 6 feet below ground surface.
Therefore, it is not anticipated that dewatering or shoring of groundwater would be required during construction.

Adherence with the CGP, including implementation of the required SWPPP and Construction BMPS, would ensure construction impacts related to surface water quality standards,waste discharge requirements,and surface water quality would be less than significant.
Operation. Pollutants of concern from long-term operations include suspended solids/sediment, nutrients, oil and grease, metals, and trash and debris.The Project would include an infiltration basin and an underground storage infiltration system that would be used for stormwater control, treatment, and infiltration.The Project would also be required to prepare a Final WQMP, consistent with the requirement of the City's M54 permit, because the Project consists of significant new development that would create 10,000 square feet or more of impervious surface.The Final WQMP would specify the Site Design,Source Control, LID,and Treatment Control BMPs that would be implemented to capture,treat,and reduce pollutants of concern in storm water runoff.Therefore, compliance with the requirements of the City and the M54 Permit would ensure that operation impacts to water quality would be less than significant.
Overall, because the Project would be required to comply with existing regulations(including the CGP and the MS4 Permit),the Project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality. Impacts would be less than significant and no mitigation is required. b. Would the project substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin?(Less Than Significant Impact)
The Project site lies within the Upper Santa Ana Valley—Chino Groundwater Basin."The basin has a surface area of approximately 154,000 acres(240 square miles)and is located in southwestern San Bernardino County.The basin is bounded by the Rialto-Colton fault to the east, impermeable rocks forming the Jurupa Mountains to the southeast, impermeable rocks of the Puente Hills and the Chino Fault to the south,the San Jose Fault on the northwest, and impermeable rocks of the San Gabriel Mountains and the Cucamonga Fault to the north.The water-bearing units in the Chino Subbasin include Holocene and Upper Pleistocene alluvium. Recharge to the basin occurs by direct infiltration or precipitation on the subbasin floor, by infiltration of surface flow,and by underflow of ground water from adjacent basins.There are five recharge facilities in the subbasin including Deer Creek, Day Creek, East Etiwanda,San Sevaine,and Victoria.Groundwater levels declined about 80 feet from historical high marks in the 1920s by 1980. By 2000,water levels had recovered about 20 feet.Total storage within the subbasin is approximately 18,300,000 acre-feet and,as of 2000,total storage is estimated to have been 5,325,000 acre-feet.49 Construction.As detailed in the Report of Geotechnical Evaluations50 completed for the Project, no groundwater was encountered within the depth of 3 feet explored and available recorded 48 California Department of Water Resources(DWR). n.d.Groundwater Basin Boundary Assessment Tool.

groundwater well data in the Project vicinity indicates historical groundwater measured at approximately 267 feet below ground.The Project would require excavation to a maximum depth of 6 feet below ground surface.Therefore, it is not anticipated that dewatering or shoring of groundwater would be required during construction,and construction activities associated with the Project would not contribute to a substantial depletion of groundwater supplies.
Operation. Development of the Project would increase impervious surface area by approximately
1.1 acres,which would decrease on-site infiltration.As described above,the Project includes BMPs to collect and infiltrate stormwater at the Project site in accordance with the M54 Permit.Therefore, development of the Project would not substantially decrease the amount of stormwater that infiltrates as compared to the existing conditions.
Water service for the Project would be provided by the City of Upland.The City's water supplies include imported water from the Metropolitan Water District of Southern California (MWD) purchased through Inland Empire Utilities Agency(IEUA),groundwater pumped from City owned wells and West End Consolidated Water Company(WECWC),groundwater purchased from SAWCo, surface water purchased from SAWCo and treated by the City,and recycled water purchased from IEUA.Therefore, operation of the Project would likely involve the use of both surface and groundwater sources for potable water.The 2020 Urban Water Management Plan indicates the City has sufficient water supplies to meet water demands through 2045, including during multiple dry years.51 Therefore,the Project's water needs would not contribute to a substantial depletion of groundwater supplies.
For the reasons listed above, impacts related to the decrease of groundwater supplies or interference with groundwater recharge would be less than significant,and no mitigation is required.
c. Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would:
I. Result in substantial erosion or siltation on-or off-site;(Less Than Significant Impact) As previously discussed,the Project site is undeveloped and does not contain any existing stormwater infrastructure.Stormwater flows to the southwest to a natural ravine which discharges into an existing ditch along the freeway right-of-way which discharges to a City of Fontana storm drain along Poplar Avenue. During construction activities, more than 1 acre of soil would be disturbed.Soil would be exposed,and drainage patterns temporarily altered during grading and other construction activities,and there would be an increased potential for soil erosion and siltation compared to existing conditions.Additionally,during a storm event,soil erosion and siltation could occur at an accelerated rate.The CGP requires the preparation of an SWPPP to identify construction BMPs to be implemented as part of the Project to reduce impacts on water quality during construction, including those impacts associated with soil erosion and siltation.With compliance 51 City of Upland.2021.City of Upland 2020 Urban Water Management Plan and Water Shortage Contingency Plan.June.

with the requirements in the CGP and implementation of construction BMPs,construction impacts related to on-or off-site erosion or siltation would be less than significant.
After the completion of Project construction,the Project would not significantly alter the existing drainage pattern of the site. However,operation of the Project would result in an increase in impervious surfaces on the Project site from approximately 0.57 to 1.65 acres, which would result in a net increase in stormwater runoff that could lead to downstream erosion in receiving waters.
However, as discussed above,the infiltration basin and underground storage infiltration system included in the Project's design would be used for stormwater control,treatment,and infiltration in compliance with the requirements of the M54 Permit. Due to the incorporation of LID techniques as required by the MS4 Permit,operational impacts related to on-or off-site erosion or siltation would be less than significant.
ii. Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on-or offsite;(Less Than Significant impact)
Development of the Project would result in an increase in impervious surfaces on the Project site from approximately 0.57 to 1.65 acres,which could have the potential to increase the volume and rate of stormwater runoff discharged from the Project site, However,as previously discussed,an infiltration basin and underground storage infiltration system included in the Project's design would be used for stormwater control,treatment, and infiltration in compliance with the requirements of the M54 Permit.The proposed drainage facilities and BMPs needed to accommodate stormwater runoff would be appropriately sized so that on-site flooding would not occur.Therefore, due to the implementation of LID techniques as required by the MS4 Permit,the Project would not substantially increase the rate or amount of surface runoff in a manner that would result in flooding on-or off site. Impacts would be less than significant, and no mitigation is required.
Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff,• (Less Than Significant impact)
Stormwater Drainage System Capacity. Under existing conditions,stormwater flows to the southwest to a natural ravine which discharges into an existing ditch along the freeway right-of-way which discharges to a City of Fontana storm drain along Poplar Avenue that discharges to the San Sevaine Channel,which flows to the Santa Ana River Reach 3,which drains to the Prado Dam. Prado Dam drains to Santa Ana River Reach 2,which flows to Santa Ana River Reach 1,which discharges to the Pacific Ocean.52 The Project would include an infiltration basin and underground storage infiltration system,which would reduce site discharge to not exceed pre-developed flow rates.The proposed drainage facilities would be designed in compliance with the MS4 Permit.The proposed drainage facilities and BMPs needed to accommodate stormwater runoff would be appropriately sized such that drainage facility capacity would not be exceeded during a design storm.Therefore, the Project would not result in an exceedance of planned or existing stormwater drainage systems, and impacts would be less than significant.

Polluted Runoff.As discussed in Section 4.10.a, pollutants of concern during construction include sediments,trash, petroleum products,concrete waste (dry and wet),sanitary waste,and chemicals, and each of these pollutants on its own or in combination with other pollutants can have a detrimental effect on water quality. Drainage patterns would be temporarily altered during grading and other construction activities, and construction-related pollutants could be spilled, leaked,or transported via storm runoff into adjacent drainages and downstream receiving waters. However, as previously discussed,the Project would be required to comply with the requirements set forth by the CGP,including preparation of an SWPPP,which would specify BMPs to be implemented to control the discharge of pollutants in stormwater runoff as a result of construction activities.
Therefore,construction-related impacts would be less than significant,and no mitigation is required.
Expected pollutants of concern from long-term operations include suspended solids/sediment, nutrients,oil and grease, metals,and trash and debris.As previously discussed, compliance with the MS4 Permit,the implementation of LID techniques,and the incorporation of operational BMPs to target pollutants of concern would ensure that the Project would not discharge substantial sources of polluted runoff from the Project site.Operation-related impacts would be less than significant, and no mitigation is required.
iv. Impede or redirect flood flows?(No Impact)
According to the Federal Emergency Management Agency(FEMA) Flood Insurance Rate Map (FIRM) No.06071C7870J,the Project site is located in Zone X,which is identified as an area of minimal flood hazard.53 The Project would not alter the topography of the Project site,which is relatively flat, and would not substantially alter drainage patterns. Because the Project would not place improvements and structures directly within a 100-year floodplain,the Project would not impede or redirect flood flows, and there would be no impact.
d. In flood hazard, tsunami, or seiche zones, would the project risk release of pollutants due to project inundation?(No Impact)
Flooding.According to FEMA FIRM No. 06071C7870J,the Project site is located in Zone X,which is identified as an area of minimal flood hazard.54 Therefore,the Project would not risk release of pollutants due to Project inundation due to flood hazard.
Tsunami.The Project site is approximately 38 miles northeast of the Pacific Ocean at an elevation over 1,600 feet above mean sea level (amsl). Based on the distance from the Pacific Ocean,the Project site is not located in a tsunami hazard zone and therefore would not be susceptible to impacts associated with a tsunami.
Seiches.Seiches are waves created in an enclosed body of water(e.g.,a bay, lake,or harbor)that go up and down or oscillate and do not progress forward like standard ocean waves. Limited isolated 53 Federal Emergency Management Agency(FEMA).2016.Flood Insurance Rate Map No.06071C7870J.Map Revised September 2,2016.Website: https://msc.fema.gov/portal/search(accessed July 5,2024). 54 Ibid.

damage to adjacent and down-slope structures has been observed from seiches occurring in swimming pools and in small shallow lakes and ponds.There are no sizeable enclosed bodies of water in the nearby vicinity of the Project site.Therefore,the Project would not risk release of pollutants due to Project inundation due to seiche.
Dam Inundation.The Project site is not located within a mapped dam failure inundation area.' Therefore,the Project site is not at risk of inundation due to dam failure,and no impact would occur.
e. Would the project conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan?(Less Than Significant Impact) The Project is within the jurisdiction of the Santa Ana RWQCB.The Santa Ana RWQCB adopted a Basin Plan(January 1995,with amendments effective on or before June 2019)that designates beneficial uses for all surface and groundwater within their jurisdiction and establishes the water quality objectives and standards necessary to protect those beneficial uses.As previously discussed, the Project would comply with existing NPDES permit requirements, including the CGP and MS4 Permit,and would implement construction and operational BMPs to reduce pollutants of concern in stormwater runoff.Compliance with these regulatory requirements would ensure that the Project would not degrade or alter water quality,cause the receiving waters to exceed the water quality objectives,or impair the beneficial use of receiving waters.As such,the Project would not result in water quality impacts that would conflict with the Basin Plan.Construction and operational impacts related to a conflict with the Basin Plan would be less than significant.
The Sustainable Groundwater Management Act(SGMA),which was enacted in September 2014, requires governments and water agencies of high-and medium-priority basins to halt overdraft of groundwater basins.The SGMA requires the formation of local Groundwater Sustainability Agencies (GSAs),which are required to adopt Groundwater Sustainability Plans (GSPs)to manage the sustainability of the groundwater basins.The Project site is in the Upper Santa Ana Valley—Chino Groundwater Basin,which the California Department of Water Resources designates as a very low priority basin.'Therefore,development of a GSP is not required for the basin associated with the Project.
As discussed above,the Project would comply with regulatory requirements to treat pollutants in stormwater runoff during construction and operation of the Project. Compliance with these regulatory requirements would ensure that stormwater that may infiltrate during construction or operation of the Project would be treated prior to reaching groundwater.Therefore,the Project would not affect groundwater quality(Upper Santa Ana Valley—Chino Groundwater Basin).As previously stated,development of the Project would increase the impervious surface on the Project site by 1.1 acres. Although,development of the Project would increase the impervious surface area 55 California Department of Water Resources(DWR).2015.

on the Project site and decrease on-site infiltration,the Project would collect and infiltrate stormwater from the Project site.Therefore,the Project would not substantially impact groundwater supplies(Upper Santa Ana Valley—Chino Groundwater Basin). Furthermore,as previously stated,the Project site is located within a very low priority basin and therefore the SGMA provisions do not apply. Impacts related to a conflict with or obstruction of a water quality control plan or sustainable groundwater management plan would be less than significant,and no mitigation is required.

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? a. Would the project physically divide an established community?(No Impact) The physical division of an established community typically refers to the construction of a physical feature(e.g.,an interstate highway or railroad tracks)or removal of a means of access(e.g.,a local road or bridge)that would impair mobility within an existing community or between a community and outlying areas. For instance,the construction of an interstate highway through an existing community may constrain travel from one side of the community to another;similarly,such construction may also impair travel to areas outside the community.
The Project would result in the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking, solar cover, landscaping, and utility improvements.The Project site is generally surrounded by a mix of residential,commercial,and industrial uses,and the Project would be consistent with the type and intensity of development in the area.Vehicular access to the Project site would be provided via two new driveways located along the northern and eastern property boundaries.The Project would not require the construction of any new infrastructure that would divide an established community and would not remove any means of access.Therefore,the Project would have no impact related to physically dividing an established community, and no mitigation is required.
b. Would the project 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?(Less Than Significant Impact)
The Project would result in the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking,solar cover, landscaping,and utility improvements.The main documents guiding development and regulating land uses in Upland are the City's General Plan and Zoning Code.The proposed use is not currently permitted at the site under the current SFR-L General Plan land use designation and RS-10 zoning.To comply with the City's General Plan and zoning regulations,the Project will require a General Plan amendment and a zone change to Public Utilities (PU) land use designation and Public/Institutional (PB/I)zoning.
The PU designation provides areas for landfills,flood control/recharge facilities and public utilities including gas, electricity,and water.The purpose of the PB/I zone is to allow for public and quasi- 4-52 PA202442O241723_San Antonio Driveway Expansion\PRODUCTS\CEQA\Public Review Draft45an Antonio Water Headquarters ISMND_was 25.docx(08108125)

public facilities that serve Upland residents and visitors.The PU designation and PB/I zone allow a maximum floor-area ratio(FAR)of 0.5.The Project would have a FAR of 0.07 and is consistent with the allowed uses of the PB/I zone and PU designation.
It should be noted that according to CEQA, policy conflicts do not, in and of themselves, constitute a significant environmental impact. Policy conflicts are considered to be environmental impacts only when they would result in direct physical impacts or where those conflicts relate to avoiding or mitigating environmental impacts.As such,associated physical environmental impacts are discussed in this 15/MND under specific topical sections.The Project would not result in any direct physical impacts that cannot be mitigated to a less than significant level.As a result of the proposed rezone and General Plan amendment,the Project would not conflict with any applicable land use plans, policies,or regulations that were adopted for the purpose of avoiding or mitigating an environmental effect,and this impact would be less than significant.

a. Would the project result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state?(No Impart) The Surface Mining and Reclamation Act(SMARA)enacted by the California Legislature in 1975 provides guidelines to assist with the classification and designation of mineral lands.Areas are classified on the basis of geologic factors without regard to existing land uses and ownership.
SMARA categorizes areas into four Mineral Resource Zones(MRZs):
• MRZ-1:An area where adequate information indicates that no significant mineral deposits are present, or where it is judged that little likelihood exists for their presence. • MRZ-2:An area where adequate information indicates that significant mineral deposits are present, or where it is judged that a high likelihood exists for their presence. • MRZ-3:An area containing mineral deposits of which their significance cannot be properly evaluated.
• MR2-4:An area where information is not adequate enough to be able to assign to any other MRZ zone.
The entire City of Upland is classified as MRZ-2. Geologic data indicate that significant PCC-Grade aggregate resources are present within the City,which is attributed to its location below the foothills of the San Gabriel Mountains and atop the San Antonio Creek and Cucamonga Creek alluvial fans.The City's known mineral resources are in the form of aggregate materials located within the San Antonio Creek and Cucamonga Creek drainage areas.57 Despite the mineral resource designations, no mineral resource extraction activities occur at the Project site under existing conditions.The Project site is not designated as a local mineral resource holding and deposit area or a sector designated by the State Mining and Geology Board as 57 City of Upland.2015a.Final Program Environmental impact Report General Plan Update(GPU 08-03), Zoning Code Update(ZCU 08-03), Climate Action Plan,and Cable Airport Land Use Compatibility Plan Update SCH No.2012041006).September 28.

containing regionally significant PCC-grade aggregate resources.58 The Project would develop the Project site with a new SAWCo headquarters and associated improvements,and no mineral resource extraction activities are proposed as part of the Project.As such,the Project would not result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the State,and no impact would occur.
b. Would the project result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan,specific plan or other land use plan?(Na Impact) The City of Upland General Plan Land Use Element does not include a land use designation specifically intended for mineral production or development of natural resources(i.e., rock and gravel production). Thus,there is no locally important mineral resource recovery site delineated on the current General Plan Land Use Map.Given existing and proposed conditions on site, implementation of the Project would not result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan,specific plan,or other land use plan. No impact would occur,and no mitigation is required. 58 City of Upland.2015b.Op.cit.

The following discussion and analyses are based on the findings included in the Noise and Vibration Impact Analysis'completed for the Project,which is included as Appendix F to this IS/MND. a. Would the project result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?(Less Than Significant Impact)
The primary existing noise sources in the Project area are transportation facilities, including SR-210 to the south.To assess the existing noise conditions in the area, long-term noise measurements were conducted at the Project site.Two long-term, 24-hour measurements were taken from July 16, 2024,to July 17, 2024.Table 4.13.A provides a summary of the existing noise levels and calculated Community Noise Equivalent Level (CNEL) level from the long-term noise level measurements.As shown in Table 4.13.A,the calculated CNEL levels reached 70.1 decibels NBA)CNEL. Hourly noise levels at surrounding uses are as low as 57.9 dBA equivalent continuous sound level {Leq) during nighttime hours and 59.8 dBA Leg during daytime hours.
Short-Term Construction-Related Impacts. Noise impacts associated with construction activities are regulated by Section 9.40.100(M)of the City's Municipal Code,which limits construction activities to the hours between 7:00 a.m.and 6:00 p.m.on weekdays.6p While the City establishes limits to the hours during which construction activity may take place,it has not established numeric maximum acceptable construction source noise levels at potentially affected receivers,which would allow for a quantified determination of what CEQA constitutes as a substantial temporary or periodic noise increase. 59 LSA.2024e.Noise and Vibration Impact Analysis for the Proposed San Antonio Water Headquarters in Upland,California(LSA Project No. 20241723).

Therefore, a numerical construction threshold based on the Federal Transit Administration's(FTA) Transit Noise and Vibration Impact Assessment Manual(FTA Manual)61 is used for analysis of daytime construction impacts.The FTA considers a daytime exterior construction noise level of 80 dBA Leg 1-hour as a reasonable threshold for residential uses,85 dBA Leq 1-hour for commercial uses, and 90 dBA Leg 1-hour for industrial land.
Two types of short-term noise impacts could occur during the construction of the Project. First, construction crew commutes and the transport of construction equipment and materials to the site for the Project would incrementally increase noise levels on access roads leading to the site.
Although there would be a relatively high single-event noise-exposure potential causing intermittent noise nuisance(passing trucks at 50 feet would generate up to 84 dBA Lmax),the effect on longer- term ambient noise levels would be small compared to existing daily traffic volumes on East 20th Street.As detailed in the Noise and Vibration Analysis completed for the Project,the expected traffic noise level increase would be approximately 1.7 dBA.A noise level increase of less than 3 dBA would not be perceptible to the human ear in an outdoor environment.Therefore,short-term, construction-related impacts associated with worker commute and equipment transport to the Project site would be less than significant.

The second type of short-term noise impact is related to noise generated during construction,which includes site preparation,grading, building construction, paving, and architectural coating on the Project site.As detailed in the Noise and Vibration Analysis completed for the Project,the Project construction composite noise levels at a distance of 50 feet(ft)would range from 74 dBA Leq to 86 dBA Leq,with the highest noise levels occurring during the grading phase.Table 4.13.E shows the nearest sensitive uses to the Project site,their distance from the center of construction activities, and composite noise levels expected during construction.These noise level projections do not consider intervening topography or barriers.

' The composite construction noise level represents the grading phase which is expected to result in the greatest noise level as compared to other phases.
dBA L,1=average A-weighted hourly noise level
While construction noise will vary, it is expected that composite noise levels during construction at the nearest sensitive residential uses to the north and west would approach 72 dBA Leg and 68 dBA Leq, respectively,during daytime hours.These predicted noise levels would only occur when all construction equipment is operating simultaneously and,therefore,are assumed to be rather conservative in nature. While construction-related short-term noise levels have the potential to be higher than existing ambient noise levels in the Project area under existing conditions,the noise impacts would no longer occur once Project construction is completed.
As stated above,the City's Noise Ordinance regulates noise impacts associated with construction activities.The Project would comply with the construction hours specified in the City's Noise Ordinance,which states that construction activities are allowed between the hours of 7:00 a.m.and 6:00 p.m.on weekdays. As it relates to off-site uses,construction-related noise impacts would remain below the 80 dBA Leq 1-hour construction noise level criteria for daytime construction noise level criteria as established by the FTA for residential land uses.Therefore, impacts would be less than significant and no mitigation is required.
Long-Term Noise Impacts.The Project would generate long-term noise impacts from both traffic and stationary noise sources,as discussed below.The City's noise standards correlate with land use zoning classifications to maintain identified ambient noise levels and to limit, mitigate,or eliminate intrusive noise that exceeds the ambient noise levels within a specified zone.As shown in Table 4.13.C,the City has adopted local guidelines based, in part,on the community noise compatibility guidelines established by the Governor's Office of Planning and Research for use in assessing the compatibility of various land use types with a range of noise levels. 4-58 PA2024420241723_San Antonio Driveway Expansion\PRODUCTS\CEQA\Public Review Oraft45an Antonio Water Headquarters ISM ND_was 25.docx(08108125)

The City of Upland Municipal Code Chapter 9.40, Unnecessary Noise, limits the noise level generated on a property that can cross to a neighboring property.The City's noise ordinance limits are presented in terms of a 1-hour average sound level and apply to residential uses only.As prescribed in Section 9.40.040,the exterior noise standards for sensitive residential uses are 55 dBA between 7:00 a.m.and 10:00 p.m. (daytime) and 45 dBA between 10:00 p.m. and 7:00 a.m. (nighttime).
Ordinance limits generally apply to"stationary"sources such as mechanical equipment, manufacturing activities, or vehicles operating on private property.
Traffic Noise Impacts.The guidelines included in the Federal Highway Administration (FHWA) Highway Traffic Noise Prediction Model (FHWA-RD-77 108)were used to evaluate highway traffic- related noise conditions along roadway segments in the Project vicinity.As detailed in the Noise and Vibration Analysis completed for the Project,the increase in Project-related traffic noise would be greater than 3 dBA,which is perceptible to the human ear in an outdoor environment. However,the generated CNEL noise levels would be below 60 dBA CNEL,which is acceptable for low-density residential uses as specified in the City's General Plan.Therefore,traffic noise impacts from Project- related traffic on off-site sensitive receptors would be less than significant, and no mitigation measures are required.
Stationary Noise Impacts.Adjacent off-site land uses would be potentially exposed to stationary- source noise impacts from rooftop heating,ventilation,and air conditioning(HVAC)equipment and proposed truck arrival and departure activities.The potential noise impacts to off-site sensitive land uses from the proposed operations are discussed below.
Heating, Ventilation,and Air Conditioning Equipment.The Project would have various rooftop mechanical equipment, including HVAC units,atop the proposed buildings. Based on the Project site plan,the Project is assumed to have two rooftop HVAC units atop each proposed building P:12024\20241723 SanAntonia Driveway Expansion\PRODUCTS\CECIMPublit Review❑raft\5an Antonio Water Headquarters ISMND_4A.DR,25.dacx(08,r02/25) 4-59

(main building and maintenance building)and assumed to operate 24 hours per day.The HVAC equipment could operate 24 hours per day and would generate sound power levels (Lw)of up to 87 dBA Lw or 72 dBA Leg at 5 feet, based on manufacturer data.62 Truck Arrival and Departure Activities. Noise levels generated by delivery trucks would be similar to noise readings from truck loading and unloading activities,which generate a noise level of 75 dBA Leg at 20 feet based on measurements taken by LSA(Operational Noise Impact Analysis for Richmond Wholesale Meat Distribution Center).63 Shorter term noise levels that occur during the docking process taken by LSA for the Operational Noise Impact Analysis for Richmond Wholesale Meat Distribution Center were measured to be 76.3 dBA Leg at 20 feet.
These noise level measures are relevant to the Project because delivery trucks are anticipated during operation of the Project. Delivery trucks would arrive on site and maneuver their trailers so that trailers would be parked within the loading docks. During this process, noise levels are associated with the truck engine noise,air brakes,and back-up alarms while the truck is backing into the dock.These noise levels would occur for a shorter period of time (less than 5 minutes).
After a truck enters the loading dock,the doors would be closed,and the remainder of the truck loading activities would be enclosed and therefore much less perceptible. Consistent with the Traffic Impact Analysis for the San Antonio Water Company Headquarters Project,"it is assumed that truck arrivals and departure activities could occur at 6 parking spaces during peak hour for a period of less than 5 minutes each.
Cumulative Operations Noise Assessment.Tables 4.13.D and 4.13.E below show the combined hourly noise levels generated by HVAC equipment and truck delivery activities at the closest off- site land uses.The results indicated that operational noise levels would be below the daytime hourly noise level standards of 55 dBA Leg for residential uses.Although the operational noise levels may exceed the nighttime hourly noise level standards of 45 dBA Le„ ambient noise levels would not increase by 5 dBA or more.Therefore, operations of the Project would be less than significant and no mitigation is required.

The criteria for environmental impacts resulting from ground-borne vibration and noise are based on the maximum levels for a single event.The City's Municipal Code does not include specific criteria for assessing vibration impacts associated with damage.Therefore,for the purpose of determining the significance of vibration impacts experienced at sensitive uses surrounding the Project site,the guidelines within the 2018 FTA Manual have been used to determine vibration impacts.The FTA Manual guidelines show that a vibration level of up to 0.2 inches per second (in/sec)in peak particle velocity(PPV) is considered safe for non-engineered timber and masonry buildings and would not result in any construction vibration damage.Therefore, in order to be conservative,the 0.2 in/sec in the PPV threshold has been used when evaluating vibration impacts at the nearest structures to the site.

Construction-Period Impacts.Ground-borne noise and vibration from construction activity would be mostly low.The closest structures,which are associated with the residential uses to the west,are approximately 60 feet from the western Project construction boundary.As detailed in the Noise and Vibration Impact Analysis completed for the Project,it is expected that vibration levels generated by dump trucks and other large equipment would generate ground-borne vibration levels of up to
0.024 PPV(in/sec)at the closest structure to the Project site.This vibration level would not exceed the 0.2 in/sec PPV threshold considered safe for non-engineered timber and masonry buildings.
Therefore,construction would not result in any vibration damage. Impacts would be less than significant, and no mitigation is required.
Long-Term Noise Impacts.The Project would not generate noticeable vibration levels related to on- site operations.Trucks traveling to and from the Project site as well as loading and unloading activities may generate vibration levels. However,the closest off-site uses are greater than 25 feet away and vibration levels generated from trucks would not be perceptible. In addition,vibration levels generated from Project-related traffic on the adjacent roadways are unusual for on-road vehicles because the rubber tires and suspension systems of on-road vehicles provide vibration isolation. Based on a reference vibration level of 0.089 in/sec PPV, structures greater than 25 feet from the roadways that contain Project trips would experience vibration levels below the most conservative standard of 0.12 in/sec PPV;therefore,vibration levels generated from Project-related traffic on the adjacent roadways would be less than significant, and no mitigation measures are required.
c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 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?(No Impact)
The nearest airport to the Project site is the Cable Airport, located approximately 2.6 miles northeast of the Project site.The Project site and surrounding sensitive uses are located well outside of the 60 dBA CNEL contour.Therefore,the Project would not be adversely affected by airport/ airfield noise. No impact would occur,and no mitigation is required. 4-62 P.\2O24\2O241723_San Antonio Driveway Eva nsion\PRODUCTS\CEQA\Public Review Oraft\5an Antonio Water Headquarters ISMND_48.0825.docx(02/08f25)

a. Would the project 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)?(Less Than Significant impact) State CEQA Guidelines Section 15126.2[d] identifies a project as growth inducing if it fosters economic or population growth, or the construction of additional housing either directly or indirectly in the surrounding environment. New employees from commercial or industrial development and new population from residential development represent direct forms of growth, which have a secondary effect of expanding the size of local markets and inducing additional economic activity in the area.
Under CEQA,growth inducement is not considered necessarily detrimental, beneficial,or of little significance to the environment.Typically,the growth-inducing potential of a project would be considered substantial if it fosters growth or a concentration of population in excess of what is assumed in pertinent master plans, land use plans,or in projections made by regional planning agencies.
The Project includes the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking,solar cover, landscaping,and utility improvements. It is anticipated that approximately 10 people would be employed on the Project site,an increase of 5 people compared to the 5 people that are currently employed on the Project site under existing conditions.
Construction of the Project would provide short-term construction jobs over an approximately 20- month period. Many of the construction jobs would be temporary and would be specific to the variety of construction activities.The workforce would include a variety of construction trade workers(e.g.,cement finishers, ironworkers,welders, carpenters, electricians, painters,and laborers).Generally,construction workers are only at a job site for the time frame in which their specific skills are needed to complete that phase of construction.Although the Project would increase the number of employees at the Project site during construction activities, it is expected that local and regional construction workers would be available to serve the Project's construction P:12024\20241723 SanAntonia Driveway Expansion\PRODUCTS\CECIMPublit ReviewOraft\5an Antonio Water Headquarters ISMND_4A.DR,25.decx(08102125) 4-63

needs.Therefore,construction of the Project would not directly or indirectly induce population growth by drawing workers from outside the area on a permanent basis.
The Project would not result in direct population growth as the use proposed is not residential and would not contribute to permanent residency on site.Although the Project would result in 5 additional employees at the Project site, it is unlikely that a substantial number of employees would relocate from outside the region to meet the need for employees resulting from implementation of the Project. Furthermore,the Project would be located within a developed area of Upland that is already served by all utilities.The existing regional infrastructure and the established roadway network would be utilized by employees accessing the Project site.The Project would not require the construction of new infrastructure,such as roads or utilities,that would indirectly induce population or growth. Furthermore,after the City's General Plan amendment and zone change,the Project would be consistent with the General Plan land use designation and zoning designation for the site and would not generate growth beyond that anticipated in the General Plan.Therefore,the Project would not directly or indirectly induce population growth, and this impact would be considered less than significant. No mitigation is required. b. Would the project displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?(No Impact) The Project includes the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking, solar cover, landscaping,and utility improvements. Under existing conditions,the Project site does not contain any residential uses and construction of the Project would not displace existing residents within the nearby residential areas.Therefore,the Project would not result in the displacement of people or housing and would not require the construction of replacement housing elsewhere, and there would be no impact.

i. Fire protection?(Less Than Significant Impact)
The San Bernardino County Fire Protection District(SBCFPD)provides fire protection and emergency medical response services throughout the City. SBCFPD's service area includes over 2 million residents within a 278 square mile region through 50 fire stations with 1,166 employees.65 There are five fire stations in Upland,with the closest fire station to the Project site being Fire Station 164 located at 1825 North Campus Avenue,approximately 0.35 mile south of the Project site.
The Project includes the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking,solar cover, landscaping,and utility improvements.The Project could result in an incremental increase in demand for fire protection service due to the increase in daytime population at the Project site as a result of additional employees at the Project site. However,the Project would be required to comply with all applicable codes for fire safety and emergency access and the Project Applicant would be required to submit plans to SBCFPD for review and approval prior to the issuance of building permits to ensure the Project would conform to applicable building and fire codes.Additionally,the Project Applicant would be required to pay a fire development impact fee 65 San Bernardino County Fire Protection District.2024.San Bernardino County Fire Statistics,Fiscal Year 2022-23.Website: https://sbcfire.org/statisticsl#statistics-total-anchor(accessed July 10,2024).

which would be directed towards maintaining adequate service levels,ensuring that any impact to fire protection services that could result from the Project would be offset by development fees.
The SBCFPD would continue providing services to the Project site and would not require additional firefighters to serve the Project.The construction of a new or expanded fire station would not be required.The Project would not result in a significant impact on the physical environment due to the incremental increase in demand for fire protection and life safety services.The incremental increase in demand for services is not expected to adversely affect existing response times to the site or within the City.Therefore, construction and operation of the Project would have a less than significant impact on fire protection and safety services and facilities. ii. Police protection?(Less Than Significant impact)
The Upland Police Department(UPD) provides police protection services to the City and Project site.
The UPD headquarters are located at 1499 West 13th Street,approximately 2.4 miles southwest of the Project site. UPD's service area includes approximately 79,000 residents within a 15.3-square- mile region. UPD includes an Operations Division,Administrative Division,Special Services and Events Division, and Traffic Division.The UPD is currently meeting its target response time of 5 minutes for Priority 1 calls which consist of in-progress emergencies where there is an immediate threat to life or an immediate need for assistance.66
The Project includes the construction of a new 3,698-square-foot SAWCo headquarters and associated improvements including a 4,066-square-foot maintenance building, maintenance yard, driveway, parking, solar cover, landscaping, and utility improvements.The Project could result in an incremental increase in demand for police protection service due to the increase in daytime population at the Project site as a result of additional employees at the Project site. However,the Project would be required to implement Crime Prevention Through Environmental Design principles, and the Project Applicant would be required to pay a police development impact fee that would be directed towards maintaining adequate service levels,ensuring that any impact to police protection services that could result from the Project would be offset by development fees.
The UPD would continue providing services to the Project site and would not require additional police officers to serve the Project.The construction of a new or expanded police station would not be required.The Project would not result in a significant impact on the physical environment due to the incremental increase in demand for police protection services.The incremental increase in demand for services is not expected to adversely affect existing responses times to the site or within the City.Therefore, construction and operation of the Project would have a less than significant impact on police protection services and facilities.

iii. Schools?(Less Than Significant Impact)
The Upland Unified School District(UUSD),which provides kindergarten through high school education,serves the educational needs in the City of Upland.The UUSD had a 2022-2023 enrollment of 10,079 students and includes 9 elementary schools, 1 TK-8th school, 2 middle schools, and 2 high schools.'
The Project does not include any residential uses,and therefore would not directly affect student population. It is anticipated that approximately 10 people would be employed on the Project site, an increase of 5 people compared to the 5 people that are currently employed on the Project site under existing conditions.A fraction of new employees hired as a result of implementation of the Project may move to the City. However,this growth would be minimal and result in an incremental increase in student population and would be spread amongst the whole school district,depending upon place of residence.Therefore,the Project would not result in a substantial increase in the number of school-age children in the area,and this impact would be less than significant. iv. Parks?(Less Than Significant Impact)
The Project does not include any residential uses and would not generate a direct need for additional park space. Park uses associated with the Project would be minimal and may include local park visits from Project employees during work shifts or on breaks.As noted above,a fraction of employees of the Project may move to the City. However,this growth would only result in an incremental increase in demand for parks,and would be spread throughout the City,depending on place of residence.Therefore,the Project would have a less than significant impact related to parks. v. Other public facilities?(Less Than Significant Impact) Development of the Project would not increase demand for other public service including libraries, community centers,and public health care facilities.As previously discussed,the Project does not include development of residential uses and would therefore not result in an increased demand for public facilities,and this impact would be less than significant. 67 National Center for Education Statistics.2024.Search for Public School Districts;District Name:Upland Unified.Website: https://nces.ed.gov/ccdidistrictsearchidistrict_detail.asp?Search=2&ID2=0600016& DistrictlD=0600016&details=1(accessed July 10,2024).
