METHODS
LITERATURE REVIEW
A literature review and record search were conducted in July 2024 to identify the existence and potential for occurrence of sensitive or special-status plant and animal species in the Project vicinity.
A thorough search of the databases for published accounts of special-status plant and animal species was conducted for the Mount Baldy 7.5-minute quadrangle that contains the Project, and for the three surrounding quadrangles: Cucamonga Peak, Guasti, and Ontario. Federal and State lists of sensitive species were also examined. Current electronic database records reviewed included the following:
• California Natural Diversity Database information (CNDDB—RareFind 5) (California Department of Fish and Wildlife [CDFW] 2024), which is administered by the CDFW,formerly known as the California Department of Fish and Game.This database covers sensitive plant and animal species, as well as sensitive natural communities that occur in California. • California Native Plant Society's (CNPS) Electronic Inventory of Rare and Endangered Vascular Plants (CNPS 2024), which uses four specific categories or "lists" of sensitive plant species to assist with the conservation of rare or endangered botanical resources. All of the plants constituting California Rare Plant Ranks 1A, 1B, 2A, and 2B are intended to meet the status definitions of"threatened" or"endangered" in the California Endangered Species Act(CESA) and the California Fish and Game Code and are considered by CNPS to be eligible for State listing. At the discretion of the CEQA Lead Agency, impacts to these species may be analyzed as such, pursuant to State CEQA Guidelines Sections 15125(c) and 15380. Plants in Rank 3 (limited information; review list), Rank 4 (limited distribution; watch list), or that are considered Locally Unusual and Significant may be analyzed under CEQA if there is sufficient information to assess potential significant impacts.
• United States Fish and Wildlife Service's (USFWS) Information for Planning and Consultation (IPaC) Online System (USFWS 2024a), which lists all proposed, candidate,threatened, and endangered species managed by the USFWS Endangered Species Program that have the potential to occur on or near a particular site.This database also lists all known critical habitats, national wildlife refuges, and migratory birds that could potentially be impacted by activities from a proposed project. An IPaC resource report was generated for the Project.
In addition to the databases listed above, historic and current aerial imagery, existing environmental reports for developments in the Project vicinity, and regional habitat conservation plans, and local land use policies related to biological resources were reviewed. Wetland resources including riparian corridors were determined using the USFWS Wetlands Mapper online edition (USFWS 2024d). Soil types were determined using the United States Department of Agriculture Natural Resources Conservation Service (NRCS)WebSoil Survey(NRCS 2024).

RECONNAISSANCE FIELD SURVEY
LSA Biologist Chrissy Kent conducted a general reconnaissance-level, pedestrian field survey on July 19, 2024, from 7:40 a.m.to 9:00 a.m. Weather conditions during the survey consisted of clear, sunny skies, with a temperature ranging from 76 to 81 degrees Fahrenheit and a light breeze of 2 to 5 miles per hour.All areas within the approximate 4.92-acre Project site were surveyed on foot, using binoculars to assist in identifying species present. Observations on general site conditions, vegetation, and habitat suitability for various special-status elements were recorded, and a list of observed and detected plant and animal species is provided in Appendix B. \\eznasunifiler1\projects\20241723_Sen Antonio Driveway Expansion\PRODUCTS\Technical Studies\Biological Resources\Draft Report\20241723_SAWH_BRA_Report.door(09/03/24) 3

RESULTS
EXISTING SITE CONDITIONS
The parcel is composed of existing developments including an underground one-million-gallon water storage tank located at the northwestern corner, a pump station located at the southwestern corner, and a signal building and tower located at the southeastern corner.Approximately five SAWCO employees within the Operations Department use the Project site on a daily basis for equipment and material storage.The existing water storage tank, pump station, and signal buildings and tower would remain in place.
The site is bordered by developed areas to the north, west, and south. Residential communities surround the north and west sides, while the south side features a developed roadway—Route 210, Foothill freeway. Directly adjacent to the Project site to the east is an undeveloped open space owned by Southern California Edison Company;this vacant lot connects to East 20th Street and is next to Holliday Rock, a ready-mix concrete supplier.The site itself primarily consists of nonnative, disturbed vegetation.The following sections discuss topography and soils,vegetation, and wildlife within the Project site.
Topography and Soils
The topography of the Project site is relatively level, with a slope of 3.9 percent and elevations ranging from 1,634 to 1,659 feet above mean sea level.
Three soil types were mapped on the Project site: Soboba stony loamy with 2 to 9 percent slopes, Soboba gravelly loamy sand with 0 to 9 percent slopes, and Hanford coarse sandy loam with 2 to 9 percent slopes (see Table A and Figure 3).These soils are not classified as hydric and have a drainage class of excessively drained and well drained (NRCS 2024).The existing soils across the Project site are highly compacted, which is indicative of long-term disturbance and consistent with the current site conditions.
Table A: Mapped Soils Classification
Soil Drainage Class Frequency of Flooding Frequency of Ponding Hydric Soil Rating Soboba stony loamy,2 to 0 Excessively Rare None No percent slopes Drained
Soboba gravelly loamy sand,0 to 9 Excessively Rare None No percent slopes Drained
Hanford coarse sandy loam,2 to 9 Well Drained Rare None No percent slopes

Vegetation and Land Cover
The Project site is almost entirely disturbed and exhibits minimal cover by native species. However, there is a small portion of the site that is composed of native scale broom (Lepidospartum squamatum). Figure 4 shows a map of vegetation and land cover types existing on the Project site, \\eznasunifilerl\projects\20241723_Sen Antonio Driveway Expansion\PRODUCTS\Technical Studies\Biological Resources\Draft Report\20241723_SAWH_BRA_Report.door(09/03/24) 4

Developed 0.64
Disturbed 4.33
Scale broom scrub 0.18
Total 5.12 _
Source:Compilation from field surveys LSA conducted on July 19,2024.
A total of nine vascular plant species were identified within the Project site during the field survey. A majority of these plant species represent non-native taxa. See Appendix B for a full list of plant species identified.
Areas mapped as disturbed land cover make up approximately 4.33 acres of the Project site and is dominated by the following nonnative plant species: erodium (Erodium cicutarium),flax-leaved horseweed (Erigeron bonariensis), and red brome (Bromus rubens).
Native land cover is entirely composed of scale broom scrub and approximately 0.18 acre would potentially be impacted by the Project.
Wetlands and Other Jurisdictional Waters
The United States Army Corps of Engineers (USACE), under Section 404 of the federal Clean Water Act (CWA), regulates discharges of dredged or fill material into "waters of the United States."These waters include wetlands and non-wetland bodies of water that meet specific criteria, including a connection to interstate commerce.This connection may be direct (through a tributary system linking a stream channel with traditional navigable waters used in interstate or foreign commerce) or it may be indirect (through a connection identified in USACE regulations).The USACE typically regulates as non-wetland waters of the United States any body of water displaying an "ordinary high-water mark."To be considered a "jurisdictional wetland" under Section 404, an area must possess hydrophytic vegetation, hydric soils, and wetland hydrology.The CDFW, under Sections 1600 et seq. of the California Fish and Game Code, regulates alterations to lakes, rivers, and streams. A stream is defined by the presence of a channel bed and banks and at least an occasional flow of water.The Regional Water Quality Control Board (RWQCB) is responsible for the administration of Section 401 of the CWA through water quality certification of any activity that may result in a discharge to jurisdictional waters of the United States.The RWQCB may also regulate discharges to "waters of the State," including wetlands, under the California Porter-Cologne Water Quality Control Act.
No drainage features, ponded areas, wetlands, or riparian habitat subject to jurisdiction of CDFW, USACE, and/or RWQCB were found within the Project site. \\eznasunifilerl\projects\20241723_Sen Antonio Driveway Expansion\PRODUCTS\Technical Studies\Biological Resources\Draft Report\20241723_SAWH_BRA_Report.door(09/03/24) 5

Wildlife
The disturbed vegetation occurring within the Project site is considered low-quality habitat for most native wildlife species.There are trees adjacent to the Project site and native vegetation that could contribute to nesting but would not be significantly impacted by the proposed development. A total of six wildlife species were observed in (or foraging over)the Project site during the field survey:
mourning Dove (Zenaida macroura), lesser goldfinch (Spinus psaltria), northern mockingbird (Mimus polyglottos), Anna's hummingbird (Calypte anna), and western fence lizard (Sceloporus occidentalis).
Each of these species commonly occur in and around developed areas throughout Southern California.
No federally listed, State-listed, or other special-status species or signs were observed during the field survey.The Project site lacks habitat that would attract special-status wildlife species. Based on field observations and a block security wall, there is no evidence that the site functions as a wildlife movement corridor or an important stopover point for migratory species.
Special-Status Species
No special-status plant or wildlife species were observed during the field survey, but there are three known occurrence records of special-status species within 0.5 mile of the Project.Table C, below, identifies those special-status plant and animal species with CNDDB occurrence record search, 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. It should be noted that the literature review and record search covered a large, geographically diverse area containing numerous habitat types not found within or around the Project.
None of the species identified in the literature review are expected to occur on the Project site due to historic and ongoing anthropogenic disturbances and the lack of suitable habitats for these species.

IMPACT FINDINGS
VEGETATION AND HABITAT IMPACTS
Based on the current conditions of the Project site, construction activities would result in less than significant impacts to native habitat and would not result in any direct impacts to sensitive natural communities. According to CNDDB,there are no recorded observations of natural communities of special concern with potential to occur within the Project site or vicinity. Additionally, no natural communities of special concern were observed during the biological survey.
THREATENED AND ENDANGERED SPECIES
Under provisions of Section 7(a)(2) of the federal Endangered Species Act, a federal agency that permits, licenses,funds, or otherwise authorizes a project activity must consult with the USFWS to ensure that its actions would not jeopardize the continued existence of any listed threatened or endangered species or destroy or adversely modify critical habitat.The USFWS designates as threatened or endangered species that are at risk of extinction and may also adopt recovery plans that identify specific areas that are essential to the conservation of a listed species. Critical habitat areas that may require special management considerations or protections can also be designated.
CESA is administered by the CDFW and prohibits the "take" of plant and animal species identified as either threatened or endangered in the State of California by the Fish and Game Commission (Fish and Game Code Sections 2050 to 2097). "Take" is defined as to hunt, pursue, catch, capture, or kill.
Sections 2091 and 2081 of CESA allow the CDFW to authorize exceptions to the prohibition of"take" of State-listed threatened or endangered plant and animal species for purposes such as public and private development.The CDFW requires formal consultation to ensure that a proposed project's actions would not jeopardize the continued existence of any listed species or destroy or adversely affect listed species' habitats.
As described in Table C, 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, as described in Table C, no federal or State-listed endangered plant species are expected to occur on the Project site due to the lack of suitable soils.Therefore, the Project would have no effects on federally listed endangered plant species.
No USFWS designated critical habitat is present on the Project site.Therefore, the Project would have no effects on designated critical habitat.
NON-LISTED SPECIAL-STATUS SPECIES
The following non-listed special-status species as identified in Table C are not expected to occur on the Project site due to a lack of suitable habitat: Southern California legless lizard (Anniella stebbinsi), pallid bat(Antrozous pallidus), California glossy snake (Arizona elegans occidentalis), burrowing owl (Athene cunicularia), western yellow bat(Lasiurus xanthinus), San Diego desert \\eznesunifilerl\projects\20241723_Sen Antonio Driveway Expansion\PRODUCTS\Technical Studies\Biological Resources\Draft Report\20241723_SAWH_BRA_Report.door(09/03/24) 22
BIOLOGICAL RESOURCES ASSESSMENT SAN ANTONIO WATER COMPANY HEADQUARTERS L SA SEPTEMBER 2024 UPLAND, CALIFORNIA
woodrat(Neotoma lepida intermedia), big free-tailed bat (Nyctinomops macrotis), and coast horned lizard (Phrynosoma blainvillii).These species all have a limited population distribution in Southern California.These animals have no official State or federal protection status but require consideration under CEQA.
Burrowing owls, however, 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.
Given the probability of occurrence is "Low to Moderate," LSA recommends the following impact avoidance measure:
• Preconstruction Presence/Absence Survey: 14 days prior to the commencement of proposed 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 CDFW and USFWS and prepare a Burrowing Owl Protection and Relocation Plan for approval by these agencies prior to initiating ground disturbance.
NESTING BIRDS
There are trees adjacent to or within the Project site and construction activities could result in impacts to nesting bird species. To reduce the potential impact, construction activities should try and avoid the nesting bird season (February 1 through September 15) or perform a preconstruction nesting bird survey prior to any Project activities planned during the nesting bird season to ensure compliance with the federal Migratory Bird Treaty Act and California Fish and Game Code Sections 3500-3516. Implementation of the following measures will reduce potential impacts to nesting raptors, migratory birds, and special status birds to a less than significant level under CEQA and will ensure compliance with State and federal laws protecting these avian species. • Construction Activity:The Project's construction activities will occur, if feasible, between September 16 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. \\eznesunifilerl\projects\20241723_Sen Antonio Driveway Expansion\PRODUCTS\Technical Studies\Biological Resources\Draft Report\20241723_SAWH_BRA_Report.door(09/03/24) 23
BIOLOGICAL RESOURCES ASSESSMENT SAN ANTONIO WATER COMPANY HEADQUARTERS L SA SEPTEMBER 2024 UPLAND, CALIFORNIA
• Tree Trimming and Removal: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 nest are found present during the pre-construction survey.
WILDLIFE MOVEMENT, CORRIDORS, AND NURSERY SITES
Wildlife movement includes seasonal migration along corridors as well as daily movements for foraging. Migration corridors may include areas of unobstructed movement of deer, riparian corridors providing cover for migrating birds, routes between breeding waters and upland habitat for amphibians, and areas between roosting and feeding areas for birds.
Wildlife species that occur in the Project vicinity are adapted to the urban-wildland interface and the study area is primarily developed as existing roadway infrastructure and residential development that already restrict wildlife movement.Although there is an undeveloped lot adjacent to the eastern boundary of the Project site, areas south,west, and north are fully developed and provide little to no value to wildlife movement. Because the Project site is surrounded by development and a brick wall,the Project's activities would not place any permanent barriers within any known wildlife movement corridors or interfere with habitat connectivity and therefore would not substantially limit wildlife movement more than current wildlife movement limitations. The Project site does not correspond to any landscape blocks or essential connectivity areas, as documented in the California Essential Habitat Connectivity Project report (Beier et al. 2011).
LOCAL TREE ORDINANCE
Removal of any City tree by anyone other than the City of Upland must comply by the City of Upland's local tree ordinance (12.24.100) (City of Upland Code of Ordinances 2024).Trees were observed within or adjacent to the Project site. However, the Project does not intend to disturb or remove them. Should any potential disturbance or removal of these trees become necessary,the regulations outlined in the City of Upland's Tree Ordinance would need to be followed. \\aznasundderl\projects\20241723_San Antonio Driveway Expansion\PRODUCTS\Technical Studies\Biological Resources\Draft Report\20241723_SAWH_BRA_Report.docx(09/03/24) 24

CULTURAL RESOURCES ASSESSMENT SAN ANTONIO WATER COMPANY HEADQUARTERS PROJECT L SA SEPTEMBER 2 02 4 UPLAND, CALIFORNIA
MANAGEMENT SUMMARY
LSA conducted a cultural resources assessment for the proposed San Antonio Water Company (SAWCo) Headquarters Project(Project) located at the southeast corner of East 20th Street and Flower Court (Assessor's Parcel Number [APN] 1044-091-22) in Upland, San Bernadino County, California.The subject property is approximately 5 acres in size and is currently developed with an underground water reservoir tank and related infrastructure.The Project involves developing an undeveloped portion of the subject property into a new headquarters for SAWCo, which will include two new buildings, a driveway from the intersection of Campus Avenue and East 20th Street, a vehicle gate, employee and visitor parking, a solar cover over the employee parking area, landscaping, and a citrus grove.The City of Upland (City), as Lead Agency for the Project, required this study as part of the environmental review process to comply with the California Environmental Quality Act (CEQA).
The purpose of the study is to provide the City with the necessary information and analysis to determine, as mandated by CEQA, whether the Project would cause substantial adverse changes to any historical/archaeological resources that may exist in or around the Project area. In order to identify and evaluate such resources, LSA conducted a historical/archaeological resources records search, pursued historical background research, and carried out intensive-level field surveys.
No archaeological resources are documented within 0.5 mile of the Project area, 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 appears low.
One historic-period (50 years of age or older) built environment resource, a 1930 water reservoir, was documented in the Project area and evaluated under the criteria for listing in the California Register of Historical Resources (California Register) and for designation as a Cultural Resource under the City's Historic Preservation Ordinance (Chapter 17.26 of the City of Upland Municipal Code; Appendix A).As a result of this evaluation, LSA recommends that the water reservoir is not eligible for listing in the California Register or for designation under the local ordinance.
Through the various avenues of research,this study did not encounter any"historical resources," as defined by CEQA within the Project area.Therefore, LSA recommends to the City a finding of No Impact regarding cultural (historic or prehistoric) resources. No further cultural resources investigation and no mitigation measures are recommended for the Project unless development plans undergo such changes as to include areas not covered by this study. However, standard regulatory compliance measures regarding buried cultural resources are required in conformance with Section 15064.5(e) of the State CEQA Guidelines, Public Resources Code (PRC) Section 5097.98, and State Health and Safety Code Section 7050.5.
If buried cultural materials are encountered during earthmoving operations associated with the Project area, all work in that area should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds.
