Environmental Setting
Fire Protection: The City contracts with CAL FIRE for its local service. The nearest fire station is Station 37 at 65958 Pierson Boulevard, approximately 2.6 miles north of the subject property.
Police Protection: The Desert Hot Springs Police Department is responsible for law enforcement and residents’ safety in the City. The main police station operates at 65950 Pierson Boulevard, approximately
2.6 miles north of the subject property.
Schools: The project site is located within the Palm Springs Unified School District (PSUSD), which provides public school facilities to accommodate students. The PSUSD currently operates sixteen elementary schools, four middle schools, three alternative high schools, and four high schools throughout its service area. The District uses portable classroom buildings on most campuses in addition to permanent classroom facilities. The nearest school to the project site is Two Bunch Palms Elementary School, located approximately 1.45 miles north of the subject property.
Parks: A total of 223 acres of land is dedicated for parks in the City. The City prepared its Parks and Recreation Master Plan in 2013 to guide the City’s delivery of parks and recreation facilities and services for the next 10 years (2013 to 2023). The nearest park to the project site is Desert Hot Springs Soccer Park, approximately 1.3 miles northeast of the site.
Discussion of Impacts
a) Less Than Significant Impact. The proposed project site is currently undeveloped vacant land.
The ultimate development of the proposed project site will result in the addition of an RV storage facility and one caretaker residence that would marginally increase the demand on fire service in the City. The proposed project will result in a fully sprinklered building, which will reduce the demand on fire services. Further, the proposed use is not at high risk for fire. The existing Fire Department is furnished with sufficient number of a staff (firefighting personnel) and equipment available during each 24-hour period, which should accommodate the marginal increase in the service demand.
Item Number: 3.
City of Desert Hot Springs
Date: July 2023
Project Name: Desert Storage Specific Plan
Fire personnel will be able to reach the site within the target five-minute response time. Emergency access will be provided to the property via the existing public roadway network.
The City has designed Development Impact Fees to allow new development to pay its fair share of future facilities, which will also be required of the proposed project. The project Applicant will be required to pay the City’s development impact fee.
The Fire Department will review the project site plan to ensure it meets applicable fire standards and regulations. No construction of new or expanded fire services or facilities are required for the proposed project. Project-related fire protection impacts will be less than significant. b) Less Than Significant Impact. Development of the project site could potentially result in a need for police protection services to respond to any potential incidents that may occur at the site.
However, the project site is located in a developed part of the City that currently receives police service. While a new commercial and residential land use would require services, it would not result in the need for new police personnel or facilities, as services can adequately be provided by existing personnel out of existing facilities. Therefore, this impact is less than significant. c) Less Than Significant Impact. The proposed project has the potential to generate up to 3 residents. The project will be subject to the PSUSD developer fees in place at the time development occurs, which currently stands at $4.79 per square foot of residential and $0.78 per square foot of commercial. Payment of the developer fee would mitigate potential significant impacts to school resources to less than significant levels.
d,e) Less Than Significant Impact. The proposed project will result in the development of an RV storage facility and caretaker residence, which would generate a population of up to 3 residents (0.005% of 2045 population projections). The proposed development will not induce substantial population growth that would result in significant impacts such as physical deterioration or construction of new recreational facilities or other public facilities. Less than significant impacts are anticipated.

Environmental Setting
There are several mini parks, neighborhood parks, community parks, and special use centers in the City.
For future development within the City, park acreage standards are generally established through an acreage requirement per 1,000 residents. The Subdivision Map Act and the Quimby Act (Section 66477 of the Govt. Code) relating to parkland dedication allows a city to adopt a local ordinance establishing a citywide park standard and the requirement of parkland dedication, or fair market value in-lieu fees, when there is residential development.

Environmental Setting
Existing Conditions
The Project site is currently undeveloped and does not generate any traffic. Key roads in the Project area include Dillon Road and Palm Drive. Dillion Road is an east-west Secondary I roadway partially built out with two lanes with an ultimate width of four lanes to be divided by a medium.
Palm Drive is a north-south roadway classified as an Urban Arterial south of Dillon Road, and a Primary I roadway north of Dillon Road. Palm Drive is partially buildout with two lanes in each direction north of Dillion Road, with an ultimate width of three lanes in each direction. South of Dillon Road, Palm Drive is partially built out with two lanes in each direction with an ultimate wide of four lanes in each direction.
There are currently sidewalks along the frontage of the existing mini-storage facility onsite. In the project vicinity, sidewalks are limited to frontages of developed lots.
SunLine Transit Agency provides bus transit services to the Coachella Valley, including Desert hot Springs. The nearest bus stop is on Palm Drive at Dillon Road approximately 0.25 miles east of the Project site.
Level of Service Threshold and VMT Analysis
The City’s acceptable Level of Service (LOS) for both roadway and intersection operations is Levelof-Service (LOS) D or better. Effective July 1, 2020, the California Environmental Quality Act (CEQA) Guidelines require lead agencies to adopt Vehicle Miles Traveled (VMT) as a replacement for automobile delay-based LOS as the measure for identifying transportation impacts for land use projects. Because the City of Desert Hot Springs does not have its own VMT guidelines, VMT analysis herein is based on the adopted Riverside County “Transportation Analysis Guidelines for Level of Service & Vehicle Miles Traveled.”

Project Trip Generation
Trip generation represents the amount of traffic that is both attracted to and produced by a development. To estimate the Project’s trip generation, the Project traffic analysis applied trip generation rates for Mini-Warehouse (land use code 151) and Single-Family Detached Housing (land use code 210), as provided by the Institute of Transportation Engineers (ITE) in its Trip Generation Manual 11th Edition, to the Project. Based on these rates, the Project is estimated to generate approximately 37 new trips per day, including 4 AM peak hour trips and 4 PM peak hour trips (Table 7).

Level of Service (LOS)
Roadway traffic operations are defined in terms of Level of Service (LOS), a qualitative description of traffic flow ranging from LOS A (free-flowing conditions) to LOS F (breakdown in flow resulting in stop-and-go conditions). The City’s General Plan identifies LOS D as the minimum threshold for acceptable traffic condition. According to the City’s General Plan, the intersection of Palm Drive at Dillon Road, approximately 0.25 miles east of the Project site, would operate at unacceptable levels of service at buildout (2040) after implementation of intersection improvements. This impact was found to be significant and unavoidable in the City’s General Plan Update EIR, and a statement of overriding considerations was adopted.
The City refers to the County of Riverside Transportation Analysis Guidelines (December 2020) (“TA Guidelines”) to determine if certain types of projects, because of their size, nature, or location, are exempt from the requirement of preparing a traffic impact analysis.
As specified in Appendix B of the County’s TA Guidelines, certain types of development proposals are generally exempt from the requirement to prepare a Level of Service transportation impact analysis, including the following:
Item Number: 3.
City of Desert Hot Springs
Date: July 2023
Project Name: Desert Storage Specific Plan
• Mini-storage yards
• Any use which can demonstrate, based on the most recent edition of the Trip Generation Report published by the Institute of Transportation Engineers (ITE) or other approved trip generation data, trip generation of less than 100 vehicle trips during the peak hours.
The proposed project consists of a mini-storage yard (RV storage) and is forecast to generate fewer than 100 trips during the weekday AM and PM peak hours. Therefore, further LOS analysis does not appear to be warranted based on the County’s TA Guidelines.
Impacts to Other Transportation Modes
Pedestrian: Existing pedestrian facilities in the immediate Project area are limited to a sidewalk on the south side of Dillon Road along the frontage of the existing Desert Self Storage property. These improvements will be continued west as part of the proposed Project along the frontage of the RV self-storage property. Future sidewalks are planned along Wolven Street and Beacon Way at the southern and western boundaries of the Project site, respectively, and will be constructed when future street improvements occur.
Bicycles and Transit Service: There would not be any impact to the existing Class II bicycle lanes and SunLine Transit Route in the Project vicinity. The closest bus stops are located
0.25 miles east along Palm Drive at the Dillon Road intersection. There is no bus service along Dillon Road. SunLine periodically reviews and updates its services and facilities based on ridership, budget, and community demand. The Project would have no impact on plans or policies addressing transit facilities.
Summary
Based on the traffic analysis above, the proposed Project would generate up to 37 daily vehicle trips. The LOS at the Palm Drive and Dillon Road intersection is projected to operate at unacceptable levels at General Plan buildout (2040); however, these impacts were previously considered as part of the General Plan Update EIR and statement of overriding considerations were adopted by the City. The Project would not worsen impacts at this intersection. The project would also be required to include sidewalk improvements along Dillon Road. Overall, impacts will be less than significant. b) Less than Significant Impact Pursuant to Senate Bill 743 (SB 743), CEQA Guidelines were amended to require all lead agencies to adopt vehicle miles traveled (VMT) as a replacement for automobile delay-based level of service (LOS) for identifying transportation impacts for land use projects. This statewide mandate went into effect July 1, 2020.
The County’s TA Guidelines also establish evaluation criteria for VMT analysis based on guidance from the Office of Planning and Research’s (OPR) Technical Advisory on Evaluating Transportation Impacts in CEQA (State of California, December 2018). The County’s TA Guidelines identify screening criteria for certain types of projects that typically reduce VMT and may be presumed to result in a less than significant VMT impact. They are as follows:
• Small Projects (generate less greenhouse gas emissions than threshold criteria) • Projects near High Quality Transit
• Local Servicing Retail
• Affordable Housing
• Local Essential Service
Item Number: 3.
City of Desert Hot Springs
Date: July 2023
Project Name: Desert Storage Specific Plan
• Map Based Screening
• Redevelopment Projects
To qualify for screening, a project needs to fulfill only one of the screening types listed. The Project is considered a “small project.” This applies to projects with low trip generation per existing CEQA exemptions or based on the County Greenhouse Gas Emissions Screening Tables, which identify projects that result in less than the 3,000 Metric Tons of Carbon Dioxide Equivalent (MT CO2e) per year screening level threshold. The County used the California Emissions Estimator Model (CalEEMod) to determine the maximum number of dwelling units or square footage for a variety of land uses that would remain within the 3,000 MT CO2e per year threshold established by the South Coast Air Quality Management Districts (SCAQMD). Additional documentation is contained in Appendix G of the County’s TA Guidelines.
As established by the County of Riverside, the following land use quantities are considered “small projects” that may be presumed to result in a less than significant VMT impact:
• Single Family Housing projects less than or equal to 110 Dwelling Units; or • Multi Family (low rise) Housing projects less than or equal to 147 Dwelling Units; or • Multi Family (mid-rise) Housing projects less than or equal to 194 Dwelling Units; or • General Office Building with area less than or equal to 165,000 SF; or • Retail buildings with area less than or equal to 60,000 SF; or • Warehouse (unrefrigerated) buildings with area less than or equal to 208,000 SF; or • General Light Industrial buildings with area less than or equal to 179,000 SF • Project GHG emissions less than 3,000 Metric Tons of Carbon Dioxide Equivalent (MTCO2e) as determined by a methodology acceptable to the Transportation Department; or
• Unless specified above, project trip generation is less than 110 trips per day per the ITE Trip Generation Manual or other acceptable source determined by Riverside County.
According to the traffic analysis herein, the proposed storage facility is forecast to generate fewer than 110 daily trips. Therefore, it is reasonable to presume the proposed project would result in a less than significant VMT impact since it is forecast to generate fewer daily trips than comparable land uses that satisfy the County-established screening criteria for small projects. Therefore, the Project meets the Small Projects screening threshold of the County VMT guidelines and can be determined to have less than significant impacts on circulation. The Project will not conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b).
c) No Impact. The Project is proposed to have access from Dillon Drive. Roadway improvements will be constructed in compliance with City standards and will not cause significant traffic delays or increased traffic hazards. No sharp curves, dangerous intersections, or hazardous geometric features are proposed. The Project vehicle mix will be consistent with the existing mix in the Project area. Construction plans will be coordinated with the city so that construction activity does not interfere with traffic on adjacent and nearby roads.
d) No Impact. The main driveway serves as an emergency access route. Prior to construction, the Fire and Police Departments will review the site plan to ensure safety measures are addressed, including emergency access and vehicle turnaround space.
Construction plans will be coordinated with the city and emergency providers, as needed, to assure that emergency access is maintained throughout all stages of development. No impact will occur.

Environmental Setting
As discussed under Section V, Cultural Resources, the oldest cultural resources reported in the City of Desert Hot Springs are from the “Paleo-Indian Period” which dates back to at least 11,000 B.C., which probably occur in the vicinity of fault-related mesquite and palms, as well as resources associated with mountain washes, streams and canyons.
Discussion of Impacts
a i, ii) Less Than Significant Impact with Mitigation Incorporated. Based on the CRM TECH findings, no historical or archaeological resource is known to occur at the project site’s surface. However, the site is within the ACBCI Tribe’s aboriginal territory or traditional land use area and potentially contains sub-surface archaeological resources. Therefore, mitigation measures and a monitoring program are included in Section V (Cultural Resources) to reduce potential impacts to less than significant levels, consistent with the concerns of the ACBCI.

The City conducted Tribal Consultation in conformance with both SB 18 and AB 52 requirements and contacted 14 tribes in writing in a letter dated May 30, 2023. The letter from the City indicated that all Tribes had 90 days from the date of the letter to request consultation in writing regarding the proposed Project. As of July 17, 2023, two tribes have formally responded in writing, including the Agua Caliente Band of Cahuilla Indians and the Yuhaaviatam of San Manuel Nation (formerly known as the San Manual Band of Mission Indians) (Appendix E Tribal Consultation).
The Agua Caliente Band of Cahuilla Indians (ACBCI) responded in a letter dated June 5, 2023 indicating that the site is within the Tribe’s Traditional Use Area and requested the following:
• Copies of any cultural resource documentation (report and site records) generated in connection with this project.
• A copy of the records search with associated survey reports and site records from the information center.
• A copy of the Mitigated Negative Declaration report.
• The presence of an approved Agua Caliente Native American Cultural Resource Monitor(s) during any ground disturbing activities (including archaeological testing and surveys).
Should buried cultural deposits be encountered, the Monitor may request that destructive construction halt and the Monitor shall notify a Qualified Archaeologist (Secretary of the Interior’s Standards and Guidelines) to investigate and, if necessary, prepare a mitigation plan for submission to the State Historic Preservation Officer and the Agua Caliente Tribal Historic Preservation Office.
• Formal government to government consultation under California Senate Bill 18 • Formal government to government consultation under California Assembly Bill No. 52 (AB52).
After review of the Mitigated Negative Declaration, ACBCI responded in a follow-up letter dated July 13, 2023, indicating that the concerns of the Tribe have been addressed and proper mitigation measures were provided in the ISMND (CUL-1), and that AB 52 and SB 18 consultation efforts have been concluded.
The Yuhaaviatam of San Manuel Nation (YSMN) responded in an email dated June 13, 2023, indicating that the Project is located outside the Serrano ancestral territory and, as such, the (YSMN) did not request further consultation.
If additional Tribes request Tribal consultation before the close of the 90 day request window indicated in the notification letter, which is August 29, 2023, the results of consultation will be included either as mitigation prior to the adoption of the Initial Study, or as conditions of approval.
However, the mitigation measure included in Section V, Cultural Resources, requires that an archaeologist and/or Tribal monitor be consulted should any resources be identified during grading, to assure that impacts are reduced to less than significant levels. Should a consulting tribe request additional mitigation, it will be added to this Initial Study or to conditions of approval for the Project.

Environmental Setting
Wastewater Treatment
The Coachella Valley Water District (CVWD) also provides sewer service to portions of the City of Desert Ho Springs, including the project area. The Project will extend sewer lines from an existing 15-inch sewer main in Dillion Road in the project vicinity.
CVWD maintains sewer trunk lines ranging in size from 4 to 24 inches and five sewer lift stations in City boundaries. CVWD operates five WRPs, two of which (WRP-7 and WRP-10) generate recycled water for irrigation of golf courses and large landscaped areas. Effluent from the City is conveyed to CVWD’s Cook Street treatment plant (Water Reclamation Plant No. 10), which has a total capacity of 18 million gallons per day (mgd), including 15 mgd tertiary treatment capacity. CVWD also implements the requirements of the Regional Water Quality Control Board pertaining to domestic water quality and wastewater discharge.
Domestic Water
The Project site is within the Coachella Valley Water District (CVWD) service area for domestic water. Its primary water source is groundwater extracted through a system of wells from the Whitewater River subbasin. In addition to groundwater, CVWD relies on imported water brought to the region by canals.
CVWD’s domestic water system includes 97 wells with a total daily pumping capacity of 244 million gallons.
CVWD has a total of 64 reservoirs, with an average storage capacity of 153.2 million gallons. CVWD also owns and operates the water distribution system, which is generally located under existing streets in the public right-of-way. There are existing 12-inch water lines within Dillon Road in the project vicinity.

Project Name: Desert Storage Specific Plan
CVWD is responsible, under the California Water Code, for analyzing its current and future water supply and assuring that sufficient supply is available to serve land uses within the District, through the preparation of an Urban Water Management Plan (UWMP). CVWD is required to periodically update the Plan.
Storm Water Management
The project site is located in the northern portion of the Coachella Valley. A network of natural and improved streams, storm drains, storm channels, and catch basins form the storm water drainage infrastructure within the City. The City implements standard requirements for the retention of storm flows, and participates in the National Pollution Discharge Elimination System (NPDES) to protect surface waters from pollution.
Development projects must retain the 100-year storm flow on site. Please also see Section X, Hydrology and Water Resources.
Solid Waste
Solid waste disposal services are provided by Desert Valley Disposal, Inc. (DVD), whose services include complete residential, commercial and roll-off trash disposal. Trash and recycled materials are collected from customers in the City and transported to the Lamb Canyon landfill, located at 16411 Lamb Canyon Road, Beaumont. Lambs Canyon is operated by the County of Riverside.
Discussion of Impacts
a-c) Less Than Significant Impact.
Water
The proposed project will be connected to the existing domestic water pipelines in the Dillon Road ROW, and thus will not require the relocation of facilities. As shown in Table 6 in Section X, Hydrology and Water Quality, the total projected water demand for the Project is 2.03 acre-feet per year (AFY). This accounts for 0.001% of the CVWD’s total planned increases in demand of 164,966 AFY by 2045.
In developing projections for future water demand, the CVWD partially bases its analysis on the City’s General Plan. The proposed uses are consistent with the commercial and residential land uses in the General Plan, and thus its impacts to water demand can be expected to be accounted for in the CVWD’s projections. Additionally, the Project will be required to implement all water conservation measures imposed by the CVWD for normal and drought conditions.
In conclusion, the Project’s impacts related to domestic water demand are anticipated to be less than significant.
Wastewater Treatment
The project area is currently served by CVWD wastewater services. The project will connect to these utility service networks and, other than parcel-level connections, will not require the construction or expansion of additional facilities because the proposed project will not significantly increase demand for services. Impacts will be less than significant.
The CVWD is subject to wastewater treatment standards established by the Regional Water Quality Control Board. All components of the proposed project will be required to design facilities consistent with CVWD and Regional Board standards. This will assure that impacts associated with wastewater treatment will be less than significant.
Drainage System
Christiansen & Company prepared a Preliminary Hydrology Study for the project site in May 2023.
According to the drainage report, on-site retention for the 100-year, 24-hour storm event will be provided, as per the City of Desert Hot Springs requirements. Onsite drainage facilities will consist Item Number: 3.

of valley gutters (inverted section), one 36”’x36” grate inlet, 72” Contech CMP perforated Pipe Underground Storage Chamber and proposed retention basin. The Contech Chamber shall have a total capacity of 5044 cf. Once capacity has been met in the chamber the overflow shall traverse to the onsite retention basin (25880 cf) via a 24” HDPE Storm Drainpipe. The proposed site shall contain 100% of the critical 100 yr storm event.
The Project will implement standard Best Management Practices (BMP) through the preparation of a Water Quality Management Plan (WQMP) to reduce pollutants of concern and reduce any project-related impacts to water quality, as required by the City in order to comply with the National Pollutant Discharge Elimination System (NPDES). Project-related impacts to stormwater drainage will be less than significant.
Electricity
The Project connect to the existing SCE infrastructure in the Project area. The project will not require the addition or expansion of electric power facilities.
Natural Gas
Natural gas will be provided to the Project by Southern California Gas (SoCalGas). The project will connect to existing SoCalGas infrastructure in the project area. The project will not require the addition or expansion of natural gas facilities.
Telecommunications
The project will provide local connections to the existing Frontier Communications infrastructure in the project area. The project will not require to the addition or expansion of telecommunication facilities.
d, e) Less Than Significant Impact. Solid waste transported by both public and private haulers is either recycled, reused, or transferred at a waste-to-energy facility, or disposed of at a closest landfill, Lamb Canyon landfill by Desert Valley Disposal, Inc. The Lamb Canyon Landfill has a permitted capacity of 39,681,513 cubic yards, with a maximum disposal capacity of 5,000 tons per day.

Environmental Setting
Large areas of California are at risk of fires due to the weather, topography, and native vegetation.
It continues to experience longer and more severe wildfire seasons, in part as a result of climate change and fire suppression techniques.
The California Department of Forestry and Fire Protection (CalFire) prepares maps that identify state responsibility areas (SRA), local responsibility areas (LRA), and Very High Fire Hazard Severity Zones (VHFHSZ). These maps show that the majority of Thousand Palms is in local responsibility areas and outside fire hazard zones. According to the City’s General Plan Update Figure SN-5, Wildfire Hazards, the Project area is not within or near any locally or state designated fire hazard zones or SRAs. In addition to the City’s implementation of the California Fire Code, development standards from the Riverside County Fire Department (RCFD) also apply. These standards are implemented through the review of development proposals by the RCFD in coordination with review by City staff.
Discussion of Impacts
a) No Impact. The primary emergency evacuation routes in the project vicinity include Interstate 10, Palm Drive, and Dillon Road. The project site is located in proximity to Palm Drive and Dillon Road, which provides regional access in an emergency. Development on the subject property would not substantially impair the City’s adopted emergency evacuation and response plans as the project is not proposing to amend these routes to impede emergency evacuation. No impact is anticipated.

Date: July 2023
Project Name: Desert Storage Specific Plan
b) No Impact. The project area is not located within a wildfire hazard severity zone nor a wildland-urban interface (WUI). The project site is miles from an area of wildland fire potential. Project occupants may experience decreases in air quality as a result of wildfires in the region, however, due to the project site’s distance from state responsibility areas or lands classified as very high fire hazard severity zones. No impact is anticipated. c) No Impact. The project will not require the installation or maintenance of associated infrastructure that could exacerbate fire risk or that may result in temporary or ongoing impacts to the environment. No impact is anticipated.
d) No Impact. The project site is located on a relatively flat area on the floor of the Coachella Valley where there is no potential for landslide, or post-fire slope instability. The proposed project would not expose people or structures to significant risks such as downslope or downstream flooding or landslides, post-fire slope instability, or drainage changes. No impact is anticipated.
Mitigation Measures: None required.
Monitoring: None required.

Significant
with
Mitigation
Incorporated
Less Than
Significant
Impact
No
Impact
a) Does the project have the potential to
substantially degrade the quality of the
environment, substantially reduce the habitat
of a fish or wildlife species, cause a fish or
wildlife population to drop below selfsustaining levels, threaten to eliminate a plant or animal community, substantially reduce the
number or restrict the range of a rare or
endangered plant or animal or eliminate
important examples of the major periods of
California history or prehistory?
ü
b) Does the project have impacts that are
individually limited, but cumulatively
considerable? (Cumulatively considerable
means that the incremental effects of a
project are considerable when viewed in
connection with the effects of past projects,
the effects of other current projects, and the
effects of probable future projects)?
ü
c) Does the project have environmental
effects which will cause substantial adverse
effects on human beings, either directly or
indirectly?
ü
Discussion of Impacts
a) Less Than Significant Impact with Mitigation Incorporated:
Biological Resources
The project site is an undeveloped land which is sparsely covered by native plant species which could provide habitat for nesting birds. Therefore, a pre-construction survey will be required to avoid impacts to nesting birds covered by the MBTA.
The proposed project will not significantly reduce fish or wildlife habitat or otherwise adversely impact a fish or wildlife species. The construction of the project has the potential to impact nesting birds, but the mitigation measures included in this document will reduce those impacts to less than significant levels.
The project site is located within the boundaries of a CVMSHCP jurisdiction but not within a designated conservation area and does not contain any wildlife corridors or biological linkage areas. The project is required to adhere to the Land Use Adjacency Guidelines of the CVMSHCP because it is located immediately adjacent to the Willow Hole Conservation Area and Upper Mission Creek/Big Morongo Canyon Conservation Area. The site is subject to payment of the Development Mitigation Fee to mitigate potential impacts to covered species under the CVMSHCP.
Item Number: 3.
City of Desert Hot Springs
Date: July 2023
Project Name: Desert Storage Specific Plan
Cultural Resources
The project site does not contain any historical or archaeological resource which could show major periods of California history or prehistory. Nonetheless, an archeologist and Tribal monitor shall be on site during pre-construction phases, including all earth moving activities to ensure potential impacts to archeological or tribal resources are mitigated to less than significant levels. b) Less Than Significant Impact. A significant impact could occur if the proposed project, in conjunction with related projects, would result in impacts that would be less than significant when viewed separately, but would be significant when viewed together. The impacts of the proposed project are individually limited and not cumulatively considerable. When viewed in conjunction with other closely related past, present or reasonably foreseeable future projects, cumulative impacts would not be significant.
c) Less Than Significant Impact. This project is not anticipated to have any environmental effects which would cause substantial adverse effects on human beings, either directly or indirectly, with the implementation of the City’s Municipal Code and other standard requirements and requirements of law. All potential impacts are expected to remain at less than significant levels.

1.0 INTRODUCTION
At the request of Terra Nova Planning & Research (Terra Nova), this biological resource assessment report (BRAR) was prepared by WSP Environment & Infrastructure, Inc. (WSP) for the proposed Dillon Road Desert RV Storage Facility Project (project site/project), located in the city of Desert Hot Springs, California. Information contained herein is intended to be used for compliance with the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP), California Environmental Quality Act (CEQA), as well as federal and California Endangered Species Acts.
2.0 PROJECT LOCATION / DESCRIPTION
Terra Nova is preparing the Specific Plan for a residential vehicle storage facility on APN 657- 220-003 and an upgrade to the façade of the existing storage facility on the adjoining APN 657- 220-023. Taken together the acreage of the two parcels is approximately 9.37-acres, although only APN 657-220-003 is undeveloped, -023 is already fully developed and does not support any biological resources. The project site is located on the south side of Dillon Road and is located west of Palm Drive, east of the dirt extension of Atlantic Avenue, and north of 18th Avenue, in the city of Desert Hot Springs, Riverside County, California (Appendix A – Figure 1). The project site includes two separate Assessor’s Parcel Numbers: 657-220-003 (4.69-acres) and 657-220-023 (4.68-acres). Specifically, the project site is located within the southwest ¼ of Section 7, Township 3 South; Range 5 East as shown on the United States Geological Survey (USGS) Desert Hot Springs, California, 7.5-minute topographic quadrangle (Appendix A – Figure 2). The geographic coordinates near the approximate center of the project area are 33°55'26.54" north latitude and 116°30'25.87" west longitude. The elevation of the project site ranges from approximately 815 to 830 feet above mean sea level.
3.0 REGULATORY FRAMEWORK
3.1 Federal
Endangered Species Act (ESA) – The United States Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service are the designated federal agencies accountable for administering the ESA. The ESA defines species as “endangered” or “threatened” and provides regulatory protection at the federal level.
• Section 9 of the ESA prohibits the “take” of listed (i.e., endangered or threatened) species.
The ESA’s definition of take is “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in such conduct.” Recognizing that take cannot always be avoided, Section 10(a) includes provisions for take that is incidental to, but not the purpose of, otherwise lawful activities. Specifically, Section 10(a) (1) (A) permits (authorized take permits) are issued for scientific purposes. Section 10(a) (1) (B) permits (incidental take permits) are issued for the incidental take of listed species that does not jeopardize the species.
• Section 7 (a) (2) requires federal agencies to evaluate the proposed project with respect to listed or proposed listed, species and their respective critical habitat (if applicable). Federal agencies must employ programs for the conservation of listed species and are prohibited from authorizing, funding, or carrying out any action that would jeopardize a listed species or destroy or modify its “critical habitat.”
As defined by the ESA, “individuals, organizations, states, local governments, and other nonfederal entities are affected by the designation of critical habitat only if their actions occur on federal lands, require a federal permit, license, or other authorization, or involve federal funding.
Item Number: 3.

Section 10(a) of the ESA authorizes the issuance of incidental take permits and establishes standards for the content of habitat conservation plans (see Section 3.3 below).
Migratory Bird Treaty Act (MBTA) – Treaties signed by the U.S., Great Britain, Mexico, Japan, and the countries of the former Soviet Union make it unlawful to pursue, capture, kill, and/or possess, or attempt to engage in any such conduct to any migratory bird, nest, egg or parts thereof listed in the document. As with the ESA, the MBTA also allows the Secretary of the Interior to grant permits for the incidental take of these protected migratory bird species.
National Environmental Policy Act (NEPA) – If portions of a proposed project could fall under the jurisdiction of a federal agency (i.e., U.S. Bureau of Reclamation, U.S. Army Corps of Engineers) they are subject to environmental review pursuant to NEPA. NEPA establishes certain criteria that must be adhered to for any project that is “financed, assisted, conducted or approved” by a federal agency. The federal lead agency is required to “determine whether the proposed action will significantly affect the quality of the human environment.” Section 404 of the Clean Water Act – This section of the Clean Water Act, administered by the U.S. Army Corps of Engineers (USACE), regulates the discharge of dredged and fill material into “waters of the United States.” The USACE has created a series of nationwide permits that authorize certain activities within waters of the U.S. provided that the proposed activity does not exceed the impact threshold of 0.5 acre for nationwide permits, takes steps to avoid impacts to wetlands and other designated U.S. waters where practicable, minimizes potential impacts to wetlands, and provides compensation for any remaining, unavoidable impacts through activities to restore or create wetlands. For projects that exceed the threshold for nationwide permits, individual permits under Section 404 can be issued. An inspection of the project site to determine presence or absence of potential jurisdictional wetlands and waters was conducted during the assessment for this project, none were found.
3.2 State
California Endangered Species Act (CESA) – This legislation is similar to the federal ESA, but it is administered by the California Department of Fish and Wildlife (CDFW – formerly Department of Fish and Game). The CDFW is authorized to enter into “memoranda of understanding” with individuals, public agencies, and other institutions to import, export, take, or possess state-listed species for scientific, educational, or management purposes. CESA prohibits the take of statelisted species except as otherwise provided in state law. Unlike the federal ESA, the CESA applies the take prohibitions to species currently petitioned for state-listing status (candidate species).
State lead agencies are required to consult with CDFW to ensure that actions are not likely to jeopardize the continued existence of any state-listed species or result in the destruction or degradation of occupied habitat.
California Environmental Quality Act (CEQA) – The basic goal of CEQA is to maintain a highquality environment now and in the future. The specific goals are for California's public agencies to:
1) identify the significant environmental effects of their actions; and, either 2) avoid those significant environmental effects, where feasible; or 3) mitigate those significant environmental effects, where feasible.
CEQA applies to "projects" proposed to be undertaken or requiring approval by state and local government agencies. Projects are activities that have the potential to have a physical impact on the environment and may include the enactment of zoning ordinances, the issuance of conditional use permits and the approval of tentative subdivision maps. Where a project requires approvals Item Number: 3.

Biological Resources Assessment
City of Desert Hot Springs, CA

from more than one public agency, CEQA requires one of these public agencies to serve as the "lead agency."
A "lead agency" must complete the environmental review process required by CEQA. The most basic steps of the environmental review process are to:
4) Determine if the activity is a "project" subject to CEQA. 5) Determine if the "project" is exempt from CEQA.
6) Perform an Initial Study to identify the environmental impacts of the project and determine whether the identified impacts are "significant". Based on its findings of "significance", the lead agency prepares one of the following environmental review documents:
a) Negative Declaration if it finds no "significant" impacts. b) Mitigated Negative Declaration if it finds "significant" impacts but revises the project to avoid or mitigate those significant impacts.
c) Environmental Impact Report (EIR) if it finds "significant" impacts.
While there is no ironclad definition of "significance", Article 5 of the State CEQA Guidelines (California Natural Resources Agency 2014) provides criteria to lead agencies in determining whether a project may have significant effects.
The Native Plant Protection Act (NPPA) – The NPPA includes measures to preserve, protect, and enhance rare and endangered native plant species. Definitions for “rare and endangered” are different from those contained in CESA. However, the list of species afforded protection in accordance with the NPPA includes those listed as rare and endangered under CESA. NPPA provides limitations on take as follows: “no person will import into this state, or take, possess, or sell within this state” any rare or endangered native plants, except in accordance with the provisions outlined in the act. If a landowner is notified by CDFW, pursuant to section 1903.5 that a rare or endangered plant is growing on their property, the landowner shall notify CDFW at least 10 days prior to the changing of land uses to allow CDFW to salvage the plants.
Natural Community Conservation Planning (NCCP) Program – A NCCP, which is managed by the CDFW, is intended to conserve multiple species and their associated habitats, while also providing for compatible use of private lands. Through local planning, the NCCP planning process is designed to provide protection for wildlife and natural habitats before the environment becomes so fragmented or degraded by development that species listing are required under CESA. Instead of conserving small, often isolated “islands” of habitat for just one listed species, agencies, local jurisdictions, and/or other interested parties have an opportunity through the NCCP to work cooperatively to develop plans that consider broad areas of land for conservation that would provide habitat for many species. Partners enroll in the programs, and by mutual consent, areas considered to have high conservation priorities or values are set aside and protected from development. Partners may also agree to study, monitor, and develop management plans for these high value “reserve” areas. The NCCP provides an avenue for fostering economic growth by allowing approved development in areas with lower conservation value. The project site is in a combined Habitat Conservation Plan (HCP) / NCCP, see Section 3.3.
Sections 1600-1603 of the State Fish and Game Code – The California Fish and Game (Wildlife) Code, pursuant to Sections 1600 through 1603, regulates all diversions, obstructions, or changes to the natural flow or bed, channel, or bank of any river, stream, or lake that supports fish or wildlife resources. Under state code, CDFW jurisdiction is assessed in the field based on one, or a combination, of the following criteria:
7) At minimum, intermittent, and seasonal flow through a bed or channel with banks and that also supports fish or other aquatic life.
Item Number: 3.

8) A watercourse having a surface or subsurface flow regime that supports or that has supported riparian vegetation.
9) Hydrogeomorphically distinct top-of-embankment to top-of-embankment limits. 10) Outer ground cover and canopy extents of, typically, riparian associated vegetation species that would be sustained by surface and/or subsurface waters of the watercourse.
The CDFW requires that public and private interests apply for a “Streambed Alteration Agreement” for any project that may impact a streambed or wetland. The CDFW has maintained a “no net loss” policy regarding impacts to streams and waterways and requires replacement of lost habitats on at least a 1:1 ratio.
Section 2081 of the State Fish and Game Code – Under Section 2081 of the California Fish and Game Code, the CDFW authorizes individuals or public agencies to import, export, take, or possess state endangered, threatened, or candidate species in California through permits or memoranda of understanding. These acts, which are otherwise prohibited, may be authorized through permits or “memoranda of understanding” if (1) the take is incidental to otherwise lawful activities, (2) impacts of the take are minimized and fully mitigated, (3) the permit is consistent with regulations adopted in accordance with any recovery plan for the species in question, and (4) the applicant ensures suitable funding to implement the measures required by the CDFW. The CDFW shall make this determination based on the best scientific information reasonably available and shall include consideration of the species’ capability to survive and reproduce.
Section 3505.5 of the State Fish and Game Code – This section makes it unlawful to take, possess, or destroy any birds in the order Falconiformes or Strigiformes (birds-of-prey, e.g.: owls, hawks, eagles, etc.) or to take, possess, or destroy the nest or eggs of any bird-of-prey.
Clean Water Act – The Regional Water Quality Control Board (RWQCB) regulates activities pursuant to Section 401(a)(1) of the Clean Water Act (CWA). Section 401 of the CWA specifies that certification from the State is required for any applicant requesting a federal license or permit to conduct any activity including, but not limited to, the construction or operation of facilities that may result in any discharge into navigable waters. Through the Porter Cologne Water Quality Control Act, the RWQCB asserts jurisdiction over Waters of the State of California (WSC) which is generally the same as WUS but may also include isolated waterbodies. The Porter Cologne Act defines WSC as “surface water or ground water, including saline waters, within the boundaries of the state”.
3.3 Coachella Valley Multiple Species Habitat Conservation Plan Finalized in October 2008, and amended in 2016, the CVMSHCP is a comprehensive regional plan that addresses the conservation needs of 27 species of native flora and fauna and 24 natural vegetation communities occurring throughout the Coachella Valley region of western Riverside County, California. Permits for the CVMSHCP were issued by the CDFW on September 9, 2008 and by the United States Fish and Wildlife Service (USFWS) on October 1, 2008 (TE104604-0).
Managed by the Coachella Valley Conservation Commission (CVCC), CVMSHCP participants include Riverside County, the Cities of Cathedral City, Coachella, Desert Hot Springs, Indian Wells, Indio, La Quinta, Palm Desert, Palm Springs, Rancho Mirage, as well as the Coachella Valley Association of Governments (CVAG), Coachella Valley Water District, Imperial Irrigation District, Mission Springs Water District and the California Department of Transportation (CVAG 2008, 2016).
The CVMSHCP serves two primary purposes: Balancing environmental protection and economic development objectives in the CVMSHCP planning area and simplifying compliance with endangered species related laws. The CVMSHCP accomplishes this by conserving unfragmented habitat to permanently protect and secure viable populations of the covered 27 Item Number: 3.

species within the planning area. The covered species include those plants and animals that are either currently listed as threatened or endangered, are proposed for listing, or are believed by an appointed Scientific Advisory Committee, USFWS and CDFW, to have a high probability of being proposed for listing in the future if not conserved by the CVMSHCP. The goal of the CVMSHCP is to meet the requirements of the ESA and CESA, while at the same time allowing for the economic growth (land development) within the plan area without significant delay or hidden costs. Under the CVMSHCP, land development/mitigation fees are collected from all new development projects occurring in the plan area. The purpose of this fee is to support the assembly of a preserve system for the covered species and natural vegetation communities within areas identified as having high conservation value (CVAG 2008).
4.0 METHODS
4.1 Literature Review
In preparation for the field surveys, a literature search was conducted to identify special status biological resources known from the vicinity of the project site. In the context of this report, and for the purpose of this assessment, vicinity is defined as areas within a 5-mile radius of the project site.
The literature search included a review of the following documents:
• California Natural Diversity Data Base (CNDDB) RareFind 5 (CDFW 2022a) • Special Animals List (CDFW 2022)
• California Native Plant Society's (CNPS) Inventory of Rare, Threatened, and Endangered Plants of California (CNPS 2022a)
• CVMSHCP (CVAG 2008)
• United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS). 2019. Web Soil Survey
• USGS 7.5’ Desert Hot Springs, West Seven Palms Valley, and Palm Springs, Calif. quadrangles (USGS 1972 - 2015)
Scientific nomenclature for this document follows standard reference sources: For plant communities, CVMSHCP (CVAG 2008), Sawyer et. al (2009), and/or Holland (1986); for flora, Jepson eFlora (2022) and the USDA NRCS PLANTS Database (2022); for amphibians, reptiles, and mammals, CDFW (2016); and for birds, California Bird Records Committee (2022).
4.2 Field Assessment
The field assessment was conducted on 28 October 2022 between 11:23 and 13:42 by Wood Senior Wildlife Biologist Nathan Moorhatch. The sky was clear (0% clouds), with low to moderate wind (0 - 9 mph), and warm temperatures (77°F to 81°F). On-site suitable habitat was assessed based on the presence of constituent habitat elements (e.g., soils, vegetation, and topography) characteristic of the potentially occurring special status biological resources determined by the literature review. The entire site was assessed on foot to record pertinent field data and current site conditions. Adjacent undeveloped areas within an approximate 150-meter (~500-foot) buffer zone that were unfenced and unsigned (i.e., not posted with “No Trespassing” and/or “Private Property”) were also assessed for burrowing owl (Athene cunicularia). This area was limited to vacant land located south of the project site. The site is surrounded by the existing Mariscal Cactus and Succulent Plant Nursery on its western side, by the existing Desert Self Storage facility (which is part of this project) on the east side, and by Dillon Road on the north side (see Figure 3 in Appendix A). Inaccessible areas were scanned for burrowing owl habitat and sign (i.e., burrows & perches with whitewash) with binoculars. All on-site flora and fauna observed or Item Number: 3.

otherwise detected (e.g., vocalizations, presence of scat, tracks, and/or bones) during the assessment were recorded in field notes and are included in Appendix B. General weather and site conditions were also recorded at the beginning and end of the survey. Temperatures and wind speeds were recorded with a handheld Kestrel 2000 anemometer. Percent cloud cover was visually estimated.
5.0 RESULTS
The proposed project site is surrounded by development on to the immediate east and west; and is bordered by the paved Dillon Road on the north. South of the project site is open, undeveloped land. The entire project site appears to have been routinely disturbed and has a mixture of barren, disturbed land with areas that have a sparse growth of plants concentrated mainly on the southern 2/3 of APN 657-220-003 (the adjoining 657-220-023 is already developed as a Storage Facility).
No drainage features occur within the project site. Representative site photos are included in Appendix C.
5.1 Coachella Valley Multiple Species Habitat Conservation Plan The entire project is located within the CVMSHCP fee area but is not within a conservation area.
The southwestern corner of the project site is located immediately adjacent to the Willow Hole Conservation Area, and the southern edge of the Upper Mission Creek/Big Morongo Canyon Conservation Area is located on the north side of Dillon Road across from the project site (Figure 6, Appendix A).
5.2 Weather Conditions
Weather conditions during the field assessment were sunny and warm. Skies were clear (0% cloud cover). Temperatures ranged from 77 to 81 degrees Fahrenheit. Winds were calm to moderate with wind speeds measured between 0 to 9 miles per hour.
5.3 Topography and Soils
The proposed project alignment is relatively flat. Only one soil type is mapped on the project site:
1) Myoma fine sand, 0 to 5 percent slopes (MaB) (USDA, NRCS. 2019) (Appendix A - Figure 4).
Myoma series consists of somewhat excessively drained soils that formed in recent alluvium with slopes ranging from 0 to 15 percent. Elevations typically are between 200 feet below sea level to 1,800 feet above sea level. Myoma soils were historically, and still are used for truck crops, citrus, grapes, alfalfa hay, dates, and homesites (USDA, NRCS. 2019).
The field assessment confirmed that on-site soils and substrates are typical of this area and consistent with the soil survey. Much of the area on and adjacent to the project site has been heavily altered for commercial development, road right-of-way maintenance, and the construction and maintenance of Dillon Road.
The site does not contain springs, seeps, or other wet areas. It also lacks active sand dunes, drifts, rock outcrops, significant rocky areas, and clay lenses.
5.4 Vegetation
The majority of the project site is disturbed with areas of cleared, bare ground, a cement pad indicating the former presence of a structure, and fairly extensive trash dumping throughout the undeveloped 657-220-003. Some elements of native vegetation that are common components of the Larrea tridentata – Ambrosia Dumosa Shrubland Alliance (Creosote bush – white bursage scrub) Shrubland Alliance are present. These native species are present sparsely throughout the undeveloped parcel (less so on the northern third of -003), and around the edges of 657-220-023.
There are several large Athel saltcedar (Tamarix aphylla) in a row on-site facing Dillon Road.
Item Number: 3.

A total of 18 plant species were identified across the project site during the assessment (Appendix B). These included a mixture of native and nonnative and/or weedy species. Of the 18 species observed, five were nonnative species (28%). Plant species identified within the project site include four-wing saltbush (Atriplex canescens), Russian thistle (Salsola tragus), California croton (Croton californicus), creosote bush (Larrea tridentata), Saharan mustard (Brassica tournefortii), sandpaper plant (Petalonyx thruberi), brittlebush (Encelia farinosa), and Emory’s indigo bush (Psorothamnus emoryi).
5.5 Wildlife
Vertebrate wildlife directly observed and/or detected otherwise (e.g., scat, bones, tracks, feathers, burrows, etc.) during the assessment was not diverse or abundant, limited to just seven species, most of which are common to the region (Appendix B). The low number of species observed may be attributable to the small size and disturbed nature of the survey area, and relatively brief period of time spent on the site. Wildlife observed or detected included two reptiles, three birds and two mammals: side-blotched lizard (Uta stansburiana), Great Basin whiptail (Aspidoscelis tigris tigris), common raven (Corvus corax), mourning dove (Zenaida macroura), yellow-rumped warbler (Setophaga coronata – wintering at this time of year), coyote (Canis latrans – scat) and Palm Springs round-tailed ground squirrel (Xerospermophilus tereticaudus chlorus – (heard just offsite to the south). The number of species detected does not represent the total number of species that may occur on the project site. Brief, one visit assessments are limited by the seasonal timing and short duration of the survey period as well as the nocturnal, fossorial and/or migratory habits of many animals. The disturbed condition of the project site reduces the potential for use by most special status species, as many of these require higher quality and/or more extensive areas of natural habitats. Some are habitat specialists requiring aeolian deposits, which are not currently present on the project site. No actively nesting birds were detected on or adjacent to the site during the assessment. No old, inactive bird nests were observed on or adjacent to the site.
5.6 Special Status Biological Resources
Some plant and/or animal taxa are designated as having special status due to declining populations, limited geographic distributions and/or vulnerability to climate change, habitat loss and/or fragmentation. Some have been listed as threatened or endangered by the USFWS or by the CDFW and are protected by the federal and state ESAs. Others have been identified, and are managed as sensitive by the USFWS, CDFW, or by private conservation organizations, including the CNPS, but have not been formally listed as threatened or endangered. Impacts to such species can still be considered significant under the CEQA, if not avoided, minimized and/or mitigated by specific project design and implementation.
The literature review and field visit resulted in a list of 63 special status biological resources which occur or potentially occur on the project site and greater project vicinity (4 to 5-mile radius). Tables 1-3 provide a summary of these resources, their current conservation status, habitat associations and potential to occur on the project site. No special status species were observed on-site during the assessment (Appendix B), but Palm Springs round-tailed ground squirrel was heard just south of the site.

California Native Plant Society (CNPS) designations:
California Rare Plant Ranks (CRPR) Note: According to the CNPS (http://www.cnps.org/programs/Rare_Plant/inventory/names.htm), ALL plants on Lists 1A, 1B, 2A, and 2B meet definitions for state listing as threatened or endangered under Secs. 2062 and 2067 (California Endangered Species Act) of the California Department of Fish and Game Code. Certain plants on Lists 3 and 4 do as well.
The CDFW (http://www.dfg.ca.gov/hcpb/species/t_e_spp/nat_plnt_consv.shtml) states that plants on Lists 1A, 1B, 2A, and 2B of the CNPS Inventory consist of plants that may qualify for listing, and recommends they be addressed in CEQA projects (CEQA Guidelines Section 15380). However, a plant need not be in the Inventory to be considered a rare, threatened, or endangered species under CEQA. In addition, CDFW recommends, and local governments may require, protection of plants which are regionally significant, such as locally rare species, disjunct populations of more common plants, or plants on the CNPS Lists 3 and 4.
List 1A: Plants presumed extinct in California.
List 1B: Plants rare and endangered in California and throughout their range.
List 2A: Plants presumed extirpated in California, but more common elsewhere.
List 2B: Plants rare, threatened, or endangered in California, but more common elsewhere.
List 3: Plants for which more information is needed.
List 4: Plants of limited distribution; a "watch list." CA Endemic: Taxa that occur only in California
CNPS Threat Code:
.1 - Seriously endangered in California (over 80% of occurrences threatened / high degree and immediacy of threat) .2 – Fairly endangered in California (20-80% occurrences threatened) .3 – Not very endangered in California (<20% of occurrences threatened, or no current threats known) Note: All List 1A (presumed extinct in California) and some List 3 (need more information- a review list) plants lacking any threat information receive no threat code extension. Also, these Threat Code guidelines represent a starting point in the assessment of threat level. Other factors, such as habitat vulnerability and specificity, distribution, and condition of occurrences, are also considered in setting the Threat Code.
Western Bat Working Group (WBWG) designations:
The Western Bat Working Group is comprised of agencies, organizations and individuals interested in bat research, management and conservation from the 13 western states and provinces. Its goals are (1) to facilitate communication among interested parties and reduce risks of species decline or extinction; (2) to provide a mechanism by which current information on bat ecology, distribution and research techniques can be readily accessed; and (3) to develop a forum to discuss conservation strategies, provide technical assistance and encourage education programs.
H: High: Species which are imperiled or are at high risk of imperilment based on available information on distribution, status, ecology and known threats.
M: Medium: Species which warrant a medium level of concern and need closer evaluation, more research, and conservation actions of both the species and possible threats. A lack of meaningful information is a major obstacle in adequately assessing these species' status and should be considered a threat.
L: Low: Species for which most of the existing data support stable populations, and for which the potential for major changes in status in the near future is considered unlikely. There may be localized concerns, but the overall status of the species is believed to be secure. Conservation actions would still apply for these bats, but limited resources are best used on High and Medium status species.
P: Periphery: This designation indicates a species on the edge of its range, for which no other designation has been determined.

5.7 Discussion of the Special-status Species Tables
Only one of the 29 sensitive plant species known from the greater project vicinity (based on CNDDB records within a five-mile radius of the project site) are expected to have any occurrence probability on the site. Coachella Valley milk-vetch (Astragalus lentiginosus var. coachellae) would have a low probability of occurring on the site due to the degraded nature of the site and low-quality habitat present. There is a 2004 CNDDB record (submitted by the author of this report) less than a half mile southwest of this project site near the northwest corner of the Desert Dunes Golf Course. The project site is adjacent to the CVMSHCP Willow Hole Conservation Area at its southwest corner. Coachella Valley milk-vetch is listed as one of the “Biological resource values” for this Conservation Area, and one of the conservation objectives for this area is to “Conserve at least 863 acres in the Desert Hot Springs portion of the area” for Coachella Valley milk-vetch. It should be noted that no dead or dried remains of milk-vetch that had germinated earlier this year were present on the site during the survey. Coachella Valley milk-vetch is a covered species under the CVMSHCP and payment of the required CVMSHCP development fee will mitigate any potential impacts to this species.
Many of the remaining 28 plants listed in Table 1 are known from the mountain ranges that flank the southern and western edges of the Coachella Valley and occur in completely different habitats and elevations that do not exist on the valley floor. The remaining species are not expected on the site due to a lack of habitat. The northern 1/3 of the site has been extensively disturbed (cleared) and consists of mainly barren ground with some trash deposition, an old cement pad (for a building or structure that is now gone) and does not support a native plant community. The remaining 2/3 of the site is less disturbed but has still endured moderate to heavy disturbance (please see photographs in Appendix C). Only 18 plant species were observed on the site, and five of these (28%) are nonnative, introduced species. Most of these species are common components of the Larrea tridentata – Ambrosia Dumosa Shrubland Alliance (Creosote bush – white bursage scrub). However, this Alliance is not fully developed on this site due to varying amounts of human disturbance and modification. Please refer to Table 1 for details regarding potential presence/absence of sensitive plant species on the site. Similarly, none of the three sensitive habitats known from the general project vicinity (listed in Table 2) are present on the site.
Of the 31 sensitive wildlife species listed in Table 3 as potentially occurring in the project vicinity only five (5) are thought to have potential (low) to forage over the project site or in the immediate area, with one sensitive wildlife species detected immediately adjacent to the site. Four of the species are birds and include: golden eagle (Aquila chrysaetos), prairie falcon (Falco mexicanus), black-tailed gnatcatcher (Polioptila melanura), and burrowing owl (Athene cunicularia). It should be noted that these species are expected to have a low to very low probability of foraging occasionally over or around the site, none are expected to nest on or adjacent to the project site due to a lack of suitable habitat. No burrows or appropriate manmade structures capable of supporting burrowing owls were observed on the site. No burrowing owls or their sign were observed on the site. There is a low probability that western yellow bat could forage over the site and could potentially roost in some of the remnant landscape palms remaining on the site, although these palms are small and in poor condition. A single Palm Springs round-tailed ground squirrel (Xerospermophilus tereticaudus chlorus) was heard during the survey immediately south of the site on undeveloped land. As discussed previously, the site has been moderately to extensively disturbed/altered and does not support the appropriate natural habitats required by the majority of the sensitive wildlife species presented in Table 3. Additionally, many of these species occur in habitats that are not present on or adjacent to site (for example no riparian habitat for least Bell’s vireo or other riparian-obligate species). In short, this is a relatively small (~4.69- Item Number: 3.

acre), disturbed parcel that has little potential to support both common and sensitive wildlife and plant species. The second parcel (APN 657-220-023) has already been developed as a Storage Facility and has no natural habitat. Please see Appendix C Site Photographs for a representation of conditions present on the site at the time of this survey.
5.7.1 CVMSHCP Covered Species
Seventeen (17) of the species presented in Tables 1 – 3 are conserved under the CVMSHCP:
Coachella Valley milk-vetch, triple-ribbed milk-vetch, Little San Bernardino Mountains linanthus, Mecca aster, Coachella Valley Jerusalem cricket, desert tortoise, Coachella Valley fringe-toed lizard, flat-tailed lizard, burrowing owl, crissal thrasher, Le Contes’ thrasher, least Bell’s vireo, southwestern willow flycatcher, western yellow bat, Palm Springs round-tailed ground squirrel, Peninsular bighorn sheep (DPS), and Palm Springs pocket mouse. Participation in the CVMSHCP, payment of the CVMSHCP development/mitigation fee and participation in the plan will fully mitigate project related impacts (although none are anticipated due to lack of presence) to these species. It should be remembered that apart from burrowing owl, Palm Springs roundtailed ground squirrel (heard just offsite to the south), and Coachella Valley milk-vetch, none of these species are expected to occur on or adjacent to the site. Burrowing owls have a very low potential to forage on or adjacent to the site but are not expected to permanently occupy the project site. Similarly, Coachella Valley milk-vetch is also expected to a very low potential to occur on the project site. As mentioned above, a single Palm Springs round-tailed ground squirrel was heard south of the site on undeveloped land. The small and declining palms that appear to be remnant landscape specimens are not likely to provide suitable roosting habitat for western yellow bat.
Suitable nesting habitat for burrowing owl was not observed on the site, and no burrows or burrow surrogates suitable for burrowing owl use were observed within the survey area. No burrowing owls or their sign were observed on the site. For these reasons, burrowing owl is currently not considered to be present on the project site.
5.7.2 Potentially Occurring Species Covered in the USFWS IPAC Report Eight special status species are presented in the USFWS IPAC report generated specifically for the project location. All eight species are included in and addressed in Tables 1-3 of this document. These include Coachella Valley milk-vetch, triple-ribbed milk-vetch, monarch butterfly, desert tortoise, Coachella Valley fringe-toed lizard, least Bell’s vireo, southwestern willow flycatcher, and Peninsular bighorn sheep.
Seven of these sensitive species are not expected on the project site due to the lack of appropriate habitat (including food plant in the case of the Monarch butterfly) and the overall degraded/disturbed nature of the site.
Monarch butterfly are known to occur in the area but the project site did not have any of the larval host plants (milkweed species). This species is not listed as threatened or endangered by any of the resource agencies. It is, however, a recent Candidate Species under the Federal Endangered Species Act.
No riparian habitat is present on or adjacent to the project site to support least Bell’s vireo or southwestern willow flycatcher. No habitat exists on site for desert tortoise, Coachella Valley fringe-toed lizard, Peninsular bighorn sheep or triple-ribbed milk-vetch. Coachella Valley milkvetch has a low probability of occurring on the project site due to the level of disturbance and poor habitat quality. Should project-related disturbance be conducted during the native bird nesting Item Number: 3.

season (1 February through 31 August), a nesting bird clearance survey is recommended to ensure that implementation of the proposed project does not impact nesting birds and complies with the MBTA.
6.0 DISCUSSION
The proposed project includes the development of all 4.69 acres of APN 657-220-003 as an RV Storage facility. APN 657-220-023 has already been developed as Storage Facility. While the site is surrounded by development on the north, east, and west sides, it is adjacent to undeveloped land on its southern edge. The project site does not contain any United States Army Corps of Engineers, Regional Water Quality Control Board, or CDFW jurisdictional waters. The project site is not within any CVMSHCP Conservation Areas, but is adjacent to the Willow Hole Conservation Area, and across the street from the Upper Mission Creek/Big Morongo Canyon Conservation Area. The CVMSHCP has Land Use Adjacency Guidelines that are intended to avoid or minimize indirect effects from Development adjacent to or within the Conservation Areas. Adjacent means sharing a common boundary with any parcel in a Conservation Area. Such indirect effects are commonly referred to as edge effects, and may include noise, lighting, drainage, intrusion of people, and the introduction of non-native plants and non-native predators such as dogs and cats.
A description of these guidelines are:
• Drainage: Proposed Development adjacent to or within a Conservation Area shall incorporate plans to ensure that the quantity and quality of runoff discharged to the adjacent Conservation Area is not altered in an adverse way when compared with existing conditions.
• Toxics: Land uses proposed adjacent to or within a Conservation Area that use chemicals or generate bioproducts such as manure that are potentially toxic or may adversely affect wildlife and plant species, Habitat, or water quality shall incorporate measures to ensure that application of such chemicals does not result in any discharge to the adjacent Conservation Area.
• Lighting: For proposed Development adjacent to or within a Conservation Area, lighting shall be shielded and directed toward the developed area. Landscape shielding or other appropriate methods shall be incorporated in project designs to minimize the effects of lighting adjacent to or within the adjacent Conservation Area in accordance with the guidelines to be included in the Implementation Manual. • Noise: Proposed Development adjacent to or within a Conservation Area that generates noise in excess of 75 dBA Leq hourly shall incorporate setbacks, berms, or walls, as appropriate, to minimize the effects of noise on the adjacent Conservation Area in accordance with the guidelines to be included in the Implementation Manual. • Invasives: Invasive, non-native plant species shall not be incorporated in the landscape for land uses adjacent to or within a Conservation Area. Landscape treatments within or adjacent to a Conservation Area shall incorporate native plant materials to the maximum extent Feasible; recommended native species are listed in Appendix D of this document. • Barriers: Land uses adjacent to or within a Conservation Area shall incorporate barriers in individual project designs to minimize unauthorized public access, domestic animal predation, illegal trespass, or dumping in a Conservation Area. Such barriers may include native landscaping, rocks/boulders, fencing, walls and/or signage. • Grading/Land Development: Manufactured slopes associated with site Development shall not extend into adjacent land in a Conservation Area.

Implementation of the proposed project is expected to permanently disturb all areas within the project site, which in turn may potentially result in direct or indirect disturbance to the biological resources, sensitive and otherwise, occurring, or potentially occurring on- and/or adjacent to the site. Payment of the required CVMSHCP development fee will mitigate any impacts to species covered under the plan. To prevent impacts to potentially nesting native birds protected by the MBTA and state fish and game code, the following measures should be taken:
6.1 Protection of Nesting Birds
Special status bird species covered by the CVMSHCP as well as a variety of common bird species that are excluded from coverage under the plan are all still protected by the MBTA and the state Fish and Game Code. This includes virtually all native migratory and resident bird species.
Avoidance of impacts to these birds is a requirement of the federal permit issued for the CVMSHCP. To avoid impacting nesting birds both within and outside conservation areas, either avoidance of project-related disturbance during the nesting season (1 February through 31 August) or nesting bird surveys conducted by a qualified ornithologist or biologist immediately prior to on-site disturbance during the nesting season would be required. If nesting birds are found, no work would be permitted near the nest until young have fledged. There is no established protocol for nest avoidance, however, when consulted the CDFW generally recommends avoidance buffers of about 500 feet for birds-of-prey and species listed as threatened or endangered, and 100–300 feet for unlisted songbirds.
6.2 Burrowing Owl
As noted above, no burrowing owls or their sign were observed on the site. Burrowing owls often occupy barren, open sites similar to the project site. This species nests and roosts underground so is uniquely vulnerable to ground disturbing activities. No burrows or “burrow surrogates” such as small culverts or abandoned concrete pipe sections suitable for use by burrowing owls were found on the site during the survey. Since burrowing owls can disperse from nearby occupied areas, a preconstruction survey following CDFG (2012) guidelines must be conducted prior to initiating ground-disturbing activities. Unless avoidable, all burrowing owls present must be relocated prior to any ground disturbing activities. If burrowing owls remain on-site, a Burrowing Owl Relocation and Management Plan will be prepared to describe and outline how the burrowing owl will be actively or passively relocated per CDFW guidelines. Relocation will require prior permission from the CDFW, at a minimum. Since the burrowing owl is a covered species under the CVMSHCP, additional mitigation/conservation measures will not be required.
7.0 CONCLUSION
With the implementation of the recommendations above, impacts to special status biological resources are anticipated to be avoided, minimized, and/or mitigated in accordance with the CVMSHCP and other resource agency requirements.

Project Code: 2023-0013280
Project Name: Desert RV Storage Site
Subject: List of threatened and endangered species that may occur in your proposed project location or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).
New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat.
A biological assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological Item Number: 3.
11/07/2022 2
evaluation similar to a biological assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a biological assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found at the Fish and Wildlife Service's Endangered Species Consultation website at:
https://www.fws.gov/endangered/what-we-do/faq.html
Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act (ESA), there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project-related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php.
The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan (when there is no federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors. For more information on avian stressors and recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-tobirds.php.
In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat. For information regarding the implementation of Executive Order 13186, please visit https://www.fws.gov/birds/policies-and-regulations/ executive-orders/e0-13186.php.
We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

EXECUTIVE SUMMARY
Between October 2022 and January 2023, at the request of Terra Nova Planning and Research, Inc., CRM TECH performed a cultural resources study on approximately nine acres of partially developed land in the City of Desert Hot Springs, Riverside County, California. The subject property of the study consists of Assessor’s Parcel Numbers 657-220-003 and -023, located on the south side of Dillon Road between Palm Drive and Atlantic Avenue, in the southwest quarter of Section 7, Township 3 South, Range 5 East, San Bernardino Baseline and Meridian.
The study is part of the environmental review process for the proposed expansion of the existing Desert Self Storage facility in the eastern portion of the project area (66251 Dillon Road) to accommodate RV storage. The expansion entails primarily the construction of enclosed and outside RV spaces, a caretaker residence, a retaining basin, a perimeter wall/fence, and paved driveways and parking spaces, along with the installation of utility lines, on the western portion of the project area. The City of Desert Hot Springs, as the lead agency for the project, required the study in compliance 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 whether the proposed project would cause substantial adverse changesto any “historical resources,” as defined by CEQA, that may exist in or near the project area.
In order to identify such resources, CRM TECH reviewed the results of recent cultural resources records searches pertaining to the project vicinity, contacted pertinent Native American representatives, pursued historical background research, and carried out a systematic field survey. Throughout the course of the study, no potential “historical resources” were encountered within the project boundaries. Outside but adjacent to the project boundaries, Dillon Road was previously recorded into the California Historical Resources Inventory as Site 33-008410 but was determined not to be eligible for listing in the California Register of Historical Resources. In light of the lack of historic integrity in relation to its period of origin, namely the 1930s era, this study concurs with the previous evaluation of Dillon Road with regard to the segment near the project location.
Based on these findings, CRM TECH recommends to the City of Desert Hot Springs a determination of No Impact regarding “historical resources.” No further cultural resources investigation is recommended for the project unless construction plans undergo such changes as to include areas not covered by this study. However, if buried cultural materials are discovered during earth-moving operations associated with the project, all work in the immediate vicinity should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds.

1 INTRODUCTION
Between October 2022 and January 2023, at the request of Terra Nova Planning and Research, Inc., CRM TECH performed a cultural resources study on approximately nine acres of partially developed land in the City of Desert Hot Springs, Riverside County, California (Figure 1). The subject property of the study consists of Assessor’s Parcel Numbers (APN) 657-220-003 and -023, located on the south side of Dillon Road between Palm Drive and Atlantic Avenue, in the southwest quarter of Section 7, Township 3 South, Range 5 East, San Bernardino Baseline and Meridian (Figures 2, 3).
The study is part of the environmental review process for the proposed expansion of the existing Desert Self Storage facility in the eastern portion of the project area (66251 Dillon Road) to accommodate RV storage. The expansion entails primarily the construction of enclosed and outside RV spaces, a caretaker residence, a retaining basin, a perimeter wall/fence, and paved driveways and parking spaces, along with the installation of utility lines, on the western portion of the project area.
The City of Desert Hot Springs, as the lead agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA; PRC §21000, et seq.).
The purpose of the study is to provide the City with the necessary information and analysis to determine whether the proposed project would cause substantial adverse changes to any “historical resources,” as defined by CEQA, that may exist in or near the project area. In order to identify such resources, CRM TECH reviewed the results of recent cultural resources records searches pertaining to the project vicinity, contacted pertinent Native American representatives, pursued historical background research, and carried out a systematic field survey. The following report is a complete account of the methods, results, and final conclusion of the study. Personnel who participated in the study are named in the appropriate sections below, and their qualifications are provided in Appendix 1.

4 SETTING
CURRENT NATURAL SETTING
The City of Desert Hot Springs lies near the northwestern end of the Coachella Valley, a northwestsoutheast trending desert valley that constitutes the western end of the Colorado Desert. Dictated by this geographic setting, the climate and environment of the region are typical of southern California’s desert country, marked by extremes in temperature and aridity. Temperatures in the region reach over 120 degrees in summer, and dip to freezing in winter. Average annual precipitation is less than five inches, and the average annual evaporation rate exceeds three feet.
The project area is located on the sparsely populated southern outskirts of Desert Hot Springs, surrounded mostly by undeveloped land but with a few scattered commercial establishments and residential properties along Dillon Road, including a plant nursery on the adjacent property to the west (Figure 3). As mentioned above, the eastern portion of the project area, comprising APN 657- 220-023, is occupied by storage units of the Desert Self Storage, while the western portion, comprising APN 657-220-003, is currently vacant but contains foundations left by buildings that have been demolished (Figure 3).
Elevations in the project area range approximately from 830 feet to 833 feet above mean sea level, and the terrain is generally level with a slight incline towards the northwest. Surface soils consist of light brown alluvial sands of mostly granitic origin, ranging in grain size from fine-to-coarse pebbles to cobbles, with small boulders embedded in some areas. The vegetation observed in the vicinity belongs to the creosote bush scrub community, featuring mainly the namesake creosote bush, brittlebush, and saltbush, with some introduced tamarisk trees also present (Figure 4).
CULTURAL SETTING
Prehistoric Context
Numerous investigations on the history of cultural development in southern California have led researchers to propose a number of cultural chronologies for the desert regions. A specific cultural sequence for the Colorado Desert was offered by Schaefer (1994) on the basis of the many archaeological studies conducted in the area. The earliest time period identified is the Paleoindian (ca. 8,000 to 10,000-12,000 years ago), when “small, mobile bands” of hunters and gatherers, who relied on a variety of small and large game animals as well as wild plants for subsistence, roamed the region (ibid.:63). These small groups settled “on mesas and terraces overlooking larger washes” (ibid.:64). Typical artifacts and features from that period include very simple stone tools, “cleared circles, rock rings, [and] some geoglyph types” (ibid.).
The Early Archaic Period follows and dates to ca. 8,000 to 4,000 years ago. It appears that a decrease in population density occurred at this time and that the indigenous groups of the area relied more on foraging than hunting. Very few archaeological remains have been identified to this time period. The ensuing Late Archaic Period (ca. 4,000 to 1,500 years ago) is characterized by continued low population densities and groups of “flexible” sizes that settled near available seasonal food resources and relied on “opportunistic” hunting of game animals. Groundstone artifacts for food processing were prominent during this time period. The most recent period in Schaefer’s Item Number: 3.

scheme, the Late Prehistoric, dates from ca. 1,500 years ago to the time of the Spanish missions, and saw the continuation of the seasonal settlement pattern. Peoples of the Late Prehistoric Period were associated with the Patayan cultural pattern and relied more heavily on the availability of seasonal “wild plants and animal resources” (Schaefer 1994:66). It was during this period that brown and buff ware ceramics were introduced into the region.
The shores of Holocene Lake Cahuilla, during times of its presence, attracted much settlement and resource procurement; but in times of the lake’s desiccation around 1700, according to Schaefer (1994:66), the Native people moved away from its receding shores towards rivers, streams, and mountains. Numerous archaeological sites dating to this time period have been identified along the shoreline of Holocene Lake Cahuilla. Testing and mitigative excavations at these sites have recovered brown and buff ware ceramics, a variety of groundstone and projectile point types, ornaments, and cremations.
Ethnohistoric Context
The Coachella Valley is a historical center of Native American settlement, where U.S. surveyors noted large numbers of Indian villages and rancherías, occupied by the Cahuilla people, in the mid19th century. The origin of the name “Cahuilla” is unclear, but may originate from their own word Item Number: 3.
6 káwiya, meaning master or boss (Bean 1978). The Takic-speaking Cahuilla are generally divided by anthropologists into three groups, according to their geographic setting: the Pass Cahuilla of the San Gorgonio Pass-Palm Springs area, the Mountain Cahuilla of the San Jacinto and Santa Rosa Mountains and the Cahuilla Valley, and the Desert Cahuilla of the eastern Coachella Valley. The basic written sources on Cahuilla culture and history include Kroeber (1925), Strong (1929), and Bean (1978), based on information provided by such Cahuilla informants as Juan Siva, Francisco Patencio, Katherine Siva Saubel, and Mariano Saubel. The following ethnohistoric discussion is based primarily on these sources.
The Cahuilla did not have a single name that referred to an all-inclusive tribal affiliation. Instead, membership was in terms of lineages or clans. Each lineage or clan belonged to one of two main divisions of the people, known as moieties. Their moieties were named for the Wildcat, or Tuktum, and Coyote, or Istam. Members of clans in one moiety had to marry into clans from the other moiety. Individual clans had villages, or central places, and territories they called their own, for purposes of hunting game, and gathering raw materials for food, medicine, ritual, or tool use. They interacted with other clans through trade, intermarriage, and ceremonies.
Cahuilla subsistence was defined by the surrounding landscape and primarily based on the hunting and gathering of wild and cultivated foods, exploiting nearly all of the resources available in a highly developed seasonal mobility system. They were adapted to the arid conditions of the desert floor, the lacustral cycles of Holocene Lake Cahuilla, and the cooler temperatures and resources available at higher elevations in the nearby mountains. When the lake was full, or nearly full, the Cahuilla would take advantage of the resources presented by the body of fresh water, building elaborate stone fish traps. Once the lake had desiccated, they relied on the available terrestrial resources.
The Cahuilla diet included seeds, roots, wild fruits and berries, acorns, wild onions, piñon nuts, and mesquite and screw beans. Medicinal plants such as creosote, California sagebrush, yerba buena and elderberry were typically cultivated near villages (Bean and Saubel 1972). Common game animals included deer, antelope, big horn sheep, rabbits, wood rats and, when Holocene Lake Cahuilla was present, fish and waterfowl. The Cahuilla hunted with throwing sticks, clubs, nets, traps, and snares, as well as bows and arrow (Bean 1978; CSRI 2002). Common tools included manos and metates, mortars and pestles, hammerstones, fire drills, awls, arrow-straighteners, and stone knives and scrapers. These lithic tools were made from locally sourced material as well as materials procured through trade or travel. They also used wood, horn, and bone spoons and stirrers; baskets for winnowing, leaching, grinding, transporting, parching, storing, and cooking; and pottery vessels for carrying water, storage, cooking, and serving food and drink (ibid.).
Cahuilla oral tradition tells of a time before there were palms in the area, and how the people, birds, and animals enjoyed the palm fruit once it had arrived (Bean and Saubel 1972). The planting of palms by the Cahuilla is well-documented, as is their enhancement of palm stands through the practice of controlled burning (Bean and Saubel 1972; Anderson 2005). Burning palm stands would increase fruit yield dramatically by eliminating pests such as the palm borer beetle, date scales, and spider mites (Bean and Saubel 1972). Firing palm stands prevented out-of-control wildfires by eliminating dead undergrowth before it accumulated to dangerous levels. The Cahuilla also burned stands of chia to produce higher yields, and deergrass to yield straighter, more abundant stalks for basketry (Bean and Saubel 1972; Anderson 2005).

7 Population data prior to European contact is almost impossible to obtain, but estimates range from 3,600 to as high as 10,000 persons covering a territory of over 2,400 square miles. During the 19th century, the Cahuilla population was decimated as a result of European diseases, most notably smallpox, for which the Native peoples had no immunity. Today, Native Americans of Pass or Desert Cahuilla heritage are mostly affiliated with one or more of the Indian reservations in and near the Coachella Valley, including Agua Caliente, Morongo, Cabazon, Torres Martinez, and Augustine.
There has been a resurgence of traditional ceremonies in recent years, and the language, songs, and stories are now being taught to the youngest generations.
Historic Context
In 1823-1825, José Romero, José Maria Estudillo, and Romualdo Pacheco became the first noted European explorers to travel through the Coachella Valley when they led a series of expeditions in search of a route to Yuma (Johnston 1987:92-95). Due to harsh environmental conditions, few nonIndians ventured into the desert valley during the Mexican and early American periods, save a few sporadic travelers along established trails. The most important of these trails was the Cocomaricopa Trail, an ancient Indian trading route that was “discovered” in 1862 by William David Bradshaw and known after that as the Bradshaw Trail (Gunther 1984:71; Ross 1992:25). In much of the Coachella Valley, this historic wagon road traversed a similar course to that of present-day Highway 111.
During the 1860s-1870s, the Bradshaw Trail served as the main thoroughfare between coastal southern California and the Colorado River, until the completion of the Southern Pacific Railroad in 1876-1877 brought an end to its heyday (Johnston 1987:185).
Non-Indian settlement in the Coachella Valley began in the 1870s with the establishment of railroad stations along the Southern Pacific Railroad, and spread further in the 1880s after public land was opened for claims under the Homestead Act, the Desert Land Act, and other federal land laws (Laflin 1998:35-36; Robinson 1948:169-171). Farming became the dominant economic activity in the valley thanks to the development of underground water sources, often in the form of artesian wells. Around the turn of the century, the date palm was introduced into the Coachella Valley, and by the late 1910s dates were the main agricultural crop and the tree an iconic image celebrating the region as the “Arabia of America” (Shields Date Gardens 1957). Then, starting in the 1920s, a new industry featuring equestrian camps, resorts, hotels, and eventually country clubs began to spread throughout the Coachella Valley, transforming it into southern California’s premier winter retreat.
Present-day City of Desert Hot Springs is among the communities that were largely created by the Coachella Valley’s resort industry. Although sporadic settlement took place in the vicinity as early as 1908, the city owes much of its early growth to the abundance of hot mineral water along the San Andreas fault line. L.W. Coffee, who subdivided the Desert Hot Springs townsite in 1933, is also credited with the first successful development of the hot springs for commercial use (Gunther 1984:151). Advertised in the early and mid-20th century primarily for its potential for health spas and convalescent homes, Desert Hot Springs saw sufficient growth by 1944 to warrant the establishment of a post office. After a further growth spurt during the post-WWII boom, Desert Hot Springs incorporated as a city in 1963.

8 RESEARCH METHODS
RECORDS SEARCH
Upon commencement of this study, CRM TECH archaeologist Nina Gallardo reviewed the results of several historical/archaeological resources records searches completed in the vicinity between 2019 and 2021 for information pertaining to the current project area. These results, obtained from the Eastern Information Center (EIC), University of California, Riverside, provided sufficient coverage to compile a complete inventory of previously identified cultural resources and existing cultural resources reports within a one-mile radius of the project location. Previously identified cultural resources include properties designated as California Historical Landmarks, Points of Historical Interest, or Riverside County Historic Landmarks, as well as those listed in the National Register of Historic Places, the California Register of Historical Resources, or the California Historical Resources Inventory.
NATIVE AMERICAN PARTICIPATION
On October 24, 2022, CRM TECH submitted a written request to the State of California Native American Heritage Commission (NAHC) for a records search in the commission’s Sacred Lands File. In the meantime, CRM TECH contacted the nearby Agua Caliente Band of Cahuilla Indians by electronic mail for additional information on potential Native American cultural resources in the project vicinity and to arrange for tribal participation in the upcoming archaeological fieldwork.
Correspondence between CRM TECH and the Native American representatives is summarized in the sections below, and a complete record is attached to this report in Appendix 2.
HISTORICAL RESEARCH
Historical background research for this study was conducted by CRM TECH principal investigator/ historian Bai “Tom” Tang on the basis of published literature in local and regional history, archival records of the County of Riverside, U.S. General Land Office (GLO) land survey plat maps dated 1856, U.S. Geological Survey (USGS) topographic maps dated 1901-1979, and aerial/satellite photographs taken between 1972 and 2021. The historical maps are accessible at the websites of the U.S. Bureau of Land Management and the USGS, and the aerial and satellite photographs are available at the Nationwide Environmental Title Research (NETR) Online website and through the Google Earth software.
FIELD SURVEY
On December 1, 2022, CRM TECH archaeologist Hunter O’Donnell carried out the field survey of the project area. The open field in the western portion was surveyed at an intensive level by walking a series of parallel east-west transects spaced 15 meters (approximately 50 feet) apart. In the eastern portion, which is almost entirely covered by buildings, concrete pavement, and imported gravel, the survey was conducted at a reconnaissance level by inspecting the buildings and any exposed ground surface. In this way, the entire project area was inspected systematically and carefully for any evidence of human activities dating to the prehistoric or historic period (i.e., 50 years or older).
Ground visibility was generally good to excellent (85-90%) over the native surface in the western half of the project area due to the sparsely scattered vegetation growth.
