Agenda packet — San Jacinto City Council, June 2, 2026 (part 5 of 11)

2D HEC-RAS modeling is used to demonstrate that pre- and post-project velocities will be essentially equal over the EMWD and MWD easements and the existing cover over the EMWD and MWD pipes will not be scoured. The pre-project (existing condition) water surface elevations and velocities are shown in Appendix D 2D HEC-RAS Inlet Existing Model and proposed postproject water surface elevations and velocities are shown in Appendix D 2D HEC-RAS Inlet Proposed Model. Modeling results indicate slow velocities and shallow depths in the 100-Year event scenario. However, where velocities exceed 6 fps, the slope of the training berm will be armored with riprap or a cutoff wall to protect against scour – the specifics of which will be determined in the final design. Modeling results of the 2D HEC-RAS analysis are in Appendix D.

The 100-Year floodplain limits within the Line E footprint are shown in Figure 15.

The placement of the training berms was chosen to avoid disturbing the riparian habitat that is in the area below the spillway. Indeed, the training berms are placed an additional 50 to 100 feet from the riparian habitat to account for temporary construction impacts that might occur from building the berms.

4.2.4 Scour Potential
HEC-RAS was used to model flows in the following three scenarios:
• To assess the highest scour potential conditions, such as in a freshly excavated bare earth unvegetated channel, an “n” value of 0.02 was used. All of the proposed scour mitigation measures will be designed using n = 0.02.
• To assess the post-project condition with a vegetated channel of minimal vegetation density, an “n” value of 0.03 was used, and n = 0.04 was used to represent flows in a vegetated channel with maximum vegetation density. It should be noted that a “n” value of 0.03 was used to plot the HGL on the long plot in Appendix A.

4.2.5 Onsite Basin, Confluence Basin, and Pump Station
The SJCCSP proposes an “Onsite Basin” to capture onsite stormwater and nuisance flows, which works with the proposed MDP Confluence Basin and both basins will be pumped out by a proposed pump station to be located on the SJCCSP property, which will discharge flows into a downstream segment of Line E (Figure 16).

On the other hand, where the concrete-lined portion of Line E outlets to the existing downstream/offsite low flow channel to the north of the Project, as shown in Figure 11, the velocity increases to more than existing. In addition, if the San Jacinto Reservoir overflows, but the San Jacinto River is not overflowing and flooding the area, the functionality of the 60-inch diameter RCP culvert under Ramona Expressway that drains the low flow channel to which the Project drains, is absolutely critical to successful drainage of the study area. However, that capacity is limited and by the time the peak flow from Line E arrives to the culvert at Ramona Expressway, the area will already be inundated. Detailed analysis of offsite downstream properties is not included in this study.

Section 5 Right of Way & Maintenance
Maintenance obligations are currently expected to be assigned as follows, overall maintenance and easement areas are defined in Figure 17 MDP Line E Lower Reach (outlet) and Figure 18 MDP Line E Upper Reach (Inlet):
• Riverside County Flood Control & Water Conservation District Project Components
RCFC&WCD would maintain Training Berms & inlet line and grade via a drainage easement and slope easement, Line E channel (with 20-foot access roads) and owned right of way (includes Line E downstream of confluence basin to MWD right of way and starting from station 80+95 per the Long Plot in Appendix A (from station 80+95 to 82+25 access road transitions from a 15’ to 20’), RCBs, and drop structures within Right of Way, Line E and over the Casa Loma Barrel No. 1 & MWD right-of-way via a maintenance easement, geotechnical and structural measures to protect Casa Loma Barrel No 1. • City of San Jacinto
Project Components
City of San Jacinto would maintain the Line E channel segment (with 15-foot access roads) within the SJCCSP boundary via a drainage easement, onsite water quality basin, Confluence Basin, and Pump Station. The city-maintained segment of Line E ends at the downstream end of the first drop structure, which is station 80+95 per the Long Plot in Appendix A.

It should be noted that MWD will not maintain structural (structural protection of Casa Loma No. 1) or geotechnical (lightweight fill) design components of this project.

Section 6 Recommendations
Based on the analysis presented herein, it is recommended that the City and RCFC&WCD approve the proposed modifications to the MDP Line E alignment. It is also recommended that Line V be removed because this drainage area will now be accommodated by an onsite system on the SJCCSP site. MDP Line E-2 will have to cross MWD Casa Loma Barrel No. 2 to connect to MDP Line E. Feasibility of MDP Line E-2 is not within the scope of this project.

Final design of the Line E system will take place in conjunction with the development of the SJCCSP, Section 7 outlines the final design items. Other future projects will design downstream MDP facilities, Line G and Line E-2 as well as other backbone facilities throughout the City. It should also be noted that the connection of MDP Line E to the San Jacinto Spillway while crossing Casa Loma Barrel No. 2 and the San Diego Pipeline, is planned as a future project. It is recommended that the flow rates established in this report be utilized for the Final Design of Line E and Line G.

SUBJECT: Report of Findings for 2021-2022 Wet-Season Survey for Listed Branchiopods Conducted for the Villages of San Jacinto Project Site, an Approximately 514-Acre Site Located in the City of San Jacinto, Riverside County, California Dear Ms. Love:

Glenn Lukos Associates, Inc. (GLA) conducted wet-season surveys for listed branchiopods (fairy shrimp) of 58 potential seasonally ponded features at the Villages of San Jacinto Project Site (Property), a 514-acre property located in the City of San Jacinto, Riverside County, California.

Frank Wegscheider (TE-038716-4) conducted the 2021-2022 wet season survey with the objective of determining the presence or absence of federally-listed Riverside fairy shrimp (Streptocephalus woottoni), San Diego fairy shrimp (Branchinecta sandiegonensis), and vernal pool fairy shrimp (Branchinecta lynchi).

The versatile fairy shrimp (Branchinecta lindahli) was detected in 7 of the 42 features that ponded sufficiently to conduct sampling. No listed branchiopods were detected on site.

The Study Area, including the main development parcels and additional offsite road improvement areas, is generally bounded by Ramona Expressway, commercial nursey, and agricultural fields to the north, North Sanderson Avenue and agricultural fields to the east, the San Jacinto Valley Sewage Plant to the south, and an egg farm and a dairy to the west.

Transverse Mercator (UTM) coordinates approximately corresponding to the Study Area are 499080 mE and 3740693 mN.

The 2021-2022 wet season survey area consists primarily of active agricultural fields and surrounding roads and an inactive dairy facility. The majority of depressional features consisted of un-vegetated road ruts. A few features support non-native species including red brome (Bromus madritensis ssp. rubens), foxtail barley (Hordeum murinum), London rocket (Sisymbrium irio), common wheat (Triticum aestivum) and Russian thistle (Salsola tragus).

Exhibit 3 depicts the 2021-2022 wet season fairy shrimp survey area.

II. METHODOLOGY
GLA biologist David Moskovitz provided a written notification to commence wet and dry season surveys to the U.S. Fish and Wildlife Service (USFWS), Carlsbad Field Office on December 1, 2021. Rain on December 14, 2021, initiated mapping of features, conducted by Frank Wegscheider, on December 15 and 17, 2021. Several features sustained ponding or were frequently re-inundated due to irrigation run-off.

In accordance with the USFWS Survey Guidelines for the Listed Large Branchiopods (Survey Guidelines) dated November 13, 20171
, site visits were conducted within 24 hours of rain events to determine whether features contained a minimum of three centimeters (cm) of ponding.

Under typical conditions, sampling commences within seven days of initial ponding. Sampling continued weekly until the feature was dry or had been inundated continuously for 120 days. If dried features were re-inundated, sampling would begin again as above. Sampling for the presence of fairy shrimp was performed using a dip net within representative portions of the depression bottom, edges, and vertical water column when there was adequate ponding.

Specimens were placed into vials, with unique depression information, containing 95% ethanol solution. Specimens were identified in the field. Datasheets are attached as Appendix 1.

IV. RESULTS
A total of 58 features were identified as potentially suitable fairy shrimp habitat. A total of 49 features ponded and were sampled during the 2021-2022 wet season. The remaining 9 features never ponded to allow for sampling. Of the 49 features sampled, seven features supported fairy shrimp. The common, versatile fairy shrimp (Branchinecta lindahli) was detected in the seven features. No listed species were detected. Table 1 includes the wet season fairy shrimp survey 1 USFWS.

SUBJECT: Dry Season Survey Results for Listed Branchiopods Conducted for the San Jacinto Commerce Center Specific Plan (formerly the Villages at San Jacinto) Project Site, City of San Jacinto, Riverside County, California Dear Ms. Love:

This letter report documents the results of a dry season survey conducted by Glenn Lukos Associates, Inc. (GLA) for 89 depressional features at the San Jacinto Commerce Center Specific Plan Project Site (formerly the Villages at San Jacinto), an approximately 660-acre site (514-acre onsite area and 146-acre offsite area; hereafter, Study Area) located in the City of San Jacinto, Riverside County, California. GLA notified the U.S. Fish and Wildlife Service (USFWS) of the intent to perform the dry season surveys on December 1, 2021, and a revised notification was sent on November 14, 2023, to clarify changes in project acreages. Dry season soil collection was conducted on October 9, 2023.

GLA biologist David Moskovitz (PER0010680-0) performed the soil collection from the features, with assistance from GLA biologist Stephanie Cashin (TE-20280D-0) and Chris Waterston (ESPER-2380694), and from GLA trainees David Smith and Velvet Park (under supervision). Brent Helm (TE-795930-12) processed the soil samples to determine cyst presence/absence and species identification through culturing. Appendix A summarizes the results of soil analysis, which was provided to GLA in final form on August 2, 2024.

I. SITE LOCATION AND DESCRIPTION
The Study area is located in the City of San Jacinto, Riverside County, California [Exhibit 1 – Regional Map] within Sections 19, 30, and unsectioned portions of Township 4 South and Range 1 West, and Section 24 of Township 4 South, and Range 2 West of the Lakeview, California USGS 7.5-minute quadrangle map [Exhibit 2 – Vicinity Map]. The Study Area, including the Ms. Stacey Love

main development parcels and additional offsite road improvement areas, is generally bounded by Ramona Expressway, commercial nursey, and agricultural fields to the north, North Sanderson Avenue and agricultural fields to the east, the San Jacinto Valley Sewage Plant to the south, an egg farm and a dairy to the west. Universal Transverse Mercator (UTM) coordinates approximately corresponding to the Study Area are 499080 mE and 3740693 mN [Exhibit 3 – Fairy Shrimp Survey Area Map].

II. DESCRIPTION OF THE DEPRESSIONAL FEATURES
A total of 89 ponded features were included for dry season soil sampling. The features were characterized as unvegetated or vegetated. Unvegetated features include road ruts, dirt parking areas, and an agricultural fields. Vegetated features included agricultural and roadside ditches and basins. One ponded feature (Pool 95) that was included in wet season sampling was not able to be included in dry soil sampling as this feature remained ponded from irrigation run-off on the dry season sampling date.

Unvegetated (Road Ruts, Dirt Parking Areas, and Agricultural Fields) Of the 89 features included in dry season soil sampling, 70 features can be described as road ruts, dirt parking areas, and agricultural fields which were all unvegetated. Of the 70 unvegetated features, 58 features were road ruts and represented the majority of the ponded features at the Project (Pools 1,2, 4-16, 25, 26, 28, 31-56, 58, 74, 84-94, and 100). The dirt parking area included ten ponded features (Pools 63 through 72). There were two ponded features (Pools 20 and 21) associated with a flooded agricultural field.

Vegetated (Agricultural and Roadside Ditches and Basins) Of the 89 features included in dry season soil sampling, 19 features can be described as agricultural and roadside ditches and basins (Pools 22, 59-62, 73, 75-83, and 96-99) that supported at least some vegetation. Most of the ditches and basins were sparsely vegetated, commonly supporting weedy annual species including five-hook bassia (Bassia hyssopifolia), stinknet (Oncosiphon piluliferum), Russian thistle (Salsola tragus), lamb’s quarters (Chenopodium album), cheeseweed (Malva parviflora), black mustard (Brassica nigra), and annual brome grasses (Bromus sp.). Native species including Coulter’s goldfields (Lasthenia glabrata ssp. coulteri) and smooth tarplant (Centromadia pungens ssp. laevis) were observed in a few features, as well as Goodding’s willow (Salix gooddingii), mulefat (Baccharis salicifolia), and Canada horseweed (Erigeron canadensis) was observed in some of the basins.

III. METHODOLOGY
A. Soil Collection
Soil sample collection and processing followed the USFWS Survey Guidelines for the Listed Large Branchiopods, November 13, 2017 (USFWS 2017). Soil sample collection was conducted by GLA biologist David Moskovitz with assistance from Stephanie Cashin and Chris Waterston; and GLA biologists, David Smith and Velvet Park (under supervision) on October 9, 2023.

The number of samples collected for the ponded features is summarized in Table 1 below, which follows the Table 1 - Soil Sample Summary in the USFWS 2017 Survey Guidelines. Soil subsampling locations were distributed in a grid pattern to cover the entire feature with targeted collection in the lowest topographic areas that would potentially exhibit past aquatic invertebrate accumulation.

Soil samples of approximately 100 milliliters each were removed at each sub-sample location using a hand trowel and were combined into a labeled bag for each feature with the collection date, location, feature ID, name of collector, and stored for future processing. Samples were stored in a dry location out of direct sunlight until shipped for processing.

B. Soil Processing and Culturing Analysis
Soil sample processing is described in the soil analysis and cyst culturing report [Appendix A] and summarized that soil samples were prepared for analysis by dissolving the clumps of soil in a brine solution while breaking clumps by hand, then skimming and placing floating material into stacked sieves, 600-micron atop 75-micron, pushing material through the sieve by rinsing Ms. Stacey Love

with lukewarm water and gentle rubbing with brush, and finally removing material from 75- micron sieve and spread thinly into petri dishes. The sieved material was examined under a microscope for large branchiopod cysts (embryonic eggs). Cyst identification was assisted using a cyst reference collection and scanning electron micrographs of cysts (Belk 1989, Brendock et al. 2008, Gilchrist 1978, Hill and Shepard 1998, Mura 1991, Thiery et al. 1995, and Rabet 2010).

Isolated cysts were cultured and fairy shrimp were grown until mature and identified using keys and diagrams from “Fairy Shrimps of California’s Puddles, Pools, and Playas” (Eriksen and Belk 1999) and recent publications concerning identification of San Diego fairy shrimp (Branchinecta sandiegonesis) (Simovish et al. 2013, Patel et al. 2018). If listed large branchiopods were identified, mature shrimp were sacrificed in 95% ethyl alcohol as species vouchers.

IV. RESULTS OF DRY SEASON SURVEY
A total of 89 features were sampled during the 2023 dry season surveys. Of the 89 features sampled, cysts of the genus Branchinecta were identified from 54 features. The versatile fairy shrimp (Branchinecta lindahli) was hatched and identified from 32 of the 54 features with Branchinecta cysts. No listed Branchinecta species were hatched. Streptocephalus cysts were not present in any of the features [Appendix A]. No listed species were detected. Table 2 includes the results of 2023 dry season fairy shrimp soil analysis and cyst culturing. Exhibit 4 depicts the results of the 2023 dry season soil analysis and successful cyst culturing.

Representative site photographs are included as Exhibit 5.

DETECTION OF FEDERALLY-LISTED LARGE BRANCHIOPODS
AT THE

VILLAGES OF SAN JACINTO,

RIVERSIDE COUNTY, CALIFORNIA

INTRODUCTION
Helm Biological Consulting (HBC), a division of Tansley Team, Inc., was contracted by Glenn Lukos Associates, Inc. (GLA) to perform an analysis of soils collected from dry seasonallyinundated depressions (hereafter “features”) at the Villages of San Jacinto (hereafter “Project”), for the presence of large branchiopods (fairy shrimp, tadpole shrimp) that are listed as threatened or endangered under the federal Endangered Species Act (e.g., the threatened vernal pool fairy shrimp [Branchinecta lynchi], the endangered Riverside fairy shrimp [Streptocephalus woottoni]). In addition, HBC was contracted by GLA to culture large branchiopod cysts (hatch cysts and rear hatchlings to maturity for positive identification of species) obtained from the soil analysis.

The Project is located in the City of San Jacinto, Riverside County, California, south of Ramona Expressway, east of North Warren Road, west of North Sanderson Avenue, and north of Cottonwood Avenue (Figure 1). The Project resides in the southern ½ of Section 18, part of the southern ½ of Section 17, NE ¼ of Section 19, western ½ of Section 20 and a thin strip along the edge of the western ½ of Section 29 of the San Bernardino Base & Meridian of the U.S.

Dry Soil Analysis and Cyst Culturing for Large Branchiopods Villages of San Jacinto
4 METHODS
Methods followed U.S. Fish and Wildlife Service’s (USFWS 2017) Survey Guidelines for Listed Large Branchiopods for dry-season sampling and consisted of first soil collection, second soil processing and analysis, and last cyst culturing as described below.

SOIL COLLECTION
Dry soils were collected on October 9, 2023 by David Moskovitz (PER0010680-0) and Stephanie Cashin (TE-20280D-0), as authorized by USFWS Section 10(a)(1)(A) of the federal Endangered Species Act (ESA), 16 U.S.C. 1531 et seq., and its implementing regulations (Appendix A). The collected soils were delivered to HBC for subsequent processing and analysis as described below.

SOIL PROCESSING AND ANALYSIS
Soil samples obtained from GLA, on October 24, 2023, were processed and analyzed by Dr.

Brent Helm of HBC as authorized by the USFWS under recovery permit number TE-795930-12 of Section 10(a)(1)(A) of the federal ESA, 16 U.S.C. 1531 et seq., and its implementing regulations. In HBC’s laboratory, a brine solution was prepared by mixing table salt (NaCl) with lukewarm tap water in a large container. The collected soil material was placed in the brine solution. The soil material was then gently worked by hand to breakdown any persistent soil structure. The organic material rising to the top of the brine solution was skimmed off and placed in a 600-micron diameter pore-size sieve stacked atop a 75-micron diameter pore-size sieve. The soil material was processed through the top sieve by flushing it with lukewarm tap water while gently rubbing it with a soft-bristle brush. The soil retained from the 75-micron diameter pore size sieve was then removed and thinly (≈1.0 mm) spread into plastic petri dishes.

The contents of each petri dish were examined under a 10 to 252-power zoom binocular microscope. A minimum of 0.5-hour was spent searching the contents of each petri dish for large branchiopod cysts (embryonic eggs). Dr. Helm’s large branchiopod cyst reference collection and scanning electron micrographs of cysts (Belk 1989, Brendock et al. 2008, Gilchrist 1978, Hill and Shepard 1998, Mura 1991, Thiery et al. 1995, and Rabet 2010) were used to identify and compare any cysts observed within the soil samples. This processing method (described above) favors the detection of cysts belonging to the genera Branchinecta, Lepidurus, and Streptocephalus since these three genera have species that are federally listed. The presence of other aquatic macroinvertebrates encountered was also noted on the laboratory data sheet.

Because there are several species within the genus Branchinecta that could occur or are known to occur within the vicinity of the Project, cysts belonging to the genus Branchinecta observed within the soils, were cultured to determine species as described below.

Dry Soil Analysis and Cyst Culturing for Large Branchiopods Villages of San Jacinto
5 CYST CULTURING
Petri dishes containing soils with Branchinecta cysts were placed into individual six-quart plastic containers. The soils were saturated with 50o F well water (non-chlorinated) and allowed to dry.

This saturation and drying process was repeated three times. The soils were then inundated completely with 50o F well water. The containers holding the inundated soils were inserted into an environmental chamber. The environmental chamber controls were set to mimic the winter light, humidity, and temperature fluctuations of the Project’s vicinity. The contents of the containers were monitored daily for fairy shrimp hatchlings (instars).

If no hatchlings were observed after ten (10) days, the containers were removed from the environmental chamber and the soils were allowed to completely dry before reinitiating the hatching process described above. A total of three hatching attempts were performed on each soil sample.

Fairy shrimp hatchlings were feed ground fish food and reared in the environmental chamber until they were mature enough to be identified using dichotomous keys and diagrams from “Fairy Shrimps of California’s Puddles, Pools, and Playas” (Eriksen and Belk 1999) and two more recent publications concerning the identification of San Diego fairy shrimp (Branchinecta sandiegonensis) (Simovich et al. 2013, Patel et al. 2018); along with comparisons to Dr. Helm’s large branchiopod reference collection. Representative mature listed large branchiopods specimens were obtained from each container and preserved in 95% ethanol as species vouchers.

6 RESULTS

SOIL COLLECTION
Soil samples collected from a total of 89 dry features (Exhibit 1A – 1J) by GLA were processed and analyzed by HBC.

SOIL PROCESSING AND ANALYSIS
Visual examinations of the processed soils revealed the presence of cysts belonging to the genus Branchinecta in 54 of the soils collected from 89 features (Table 1). No evidence of cysts belonging to the genus Streptocephalus were observed in the processed soils. Representative photographs of the features sampled using dry-season techniques are provided in Appendix B.

CYST CULTURING
The non-special status versatile fairy shrimp (Branchinecta lindahli) was successfully hatched and raised to maturity from 32 of the 54 feature soils that were observed to have Branchinecta cysts. After three hatching attempts, a total of 1,505 fairy shrimp were hatched and 213 were raised to maturity and identified as the versatile fairy shrimp (Table 2).

SUBJECT: Revised Notification to Commence Dry Season Surveys for Listed Fairy Shrimp at the Villages of San Jacinto Project Site, an Approximately 660-Acre Site Located in the City of San Jacinto, Riverside County, California Dear Ms. Love:

Please accept this letter and attachments as a revised notification to conduct dry season surveys for listed fairy shrimp at the Villages of San Jacinto Project Site, an approximately 660-acre site (514-acre onsite area and 146-acre offsite area) located in the City of San Jacinto, Riverside County, California (Study Area).

Pursuant to the original 2021 notification, GLA performed wet season surveys for both the onsite (2021-2022) and offsite (2022-2023) areas. Also pursuant to the original notification, dry season surveys were initiated with soil sample collection on October 9, 2023 for those features sampled during the wet season surveys. Soil samples were collected by David Moskovitz (PER0010680- 0), supervising Stephanie Cashin (TE-20280D-0), per the USFWS survey protocol entitled Survey Guidelines for the Listed Large Branchiopods (dated November 13, 2017). This revised notification is being submitted to identify that soil processing and cyst culturing will be performed by Brent Helm (TE-795930-12) of Helm Biological Consulting. Within 90 days of completing the processing, a report will be submitted to USFWS documenting the dry season survey results.

The Project site is located in the City of San Jacinto, Riverside County, California [Exhibit 1 – Regional Map] within Sections 19, 30, and unsectioned portions of , Township 4 South, and Range 1 West and Section 24 of Township 4 South, and Range 2 West of the Lakeview, California USGS 7.5-minute quadrangle map [Exhibit 2 – Vicinity Map]. The Study Area, including the main development parcels and additional offsite road improvement areas, is generally bounded by Ramona Expressway, commercial nursey, and agricultural fields to the north, North Sanderson Avenue and agricultural fields to the east, the San Jacinto Valley Sewage Stacey Love

SUBJECT: Report of Findings for a Wet-Season Survey for Listed Branchiopods Conducted for the Master Drainage Plan (MDP) Line E Project, an Approximately 14,000 Linear-Foot Drainage Alignment in the City of San Jacinto, Riverside County, California
Dear Ms. Love:

Glenn Lukos Associates, Inc. (GLA) conducted wet-season surveys for listed branchiopods (fairy shrimp) of three seasonally ponded features within the Master Drainage Plan (MDP) Line E Project (Project) located in the City of San Jacinto, Riverside County.

GLA biologists Stephanie Cashin (TE-20280D-0) and Chris Waterston (ESPER-2380694) conducted the wet season surveys, assisted by GLA field staff David Smith and Velvet Park, with the objective of determining the presence or absence of federally-listed Riverside fairy shrimp (Streptocephalus woottoni), San Diego fairy shrimp (Branchinecta sandiegonensis), and vernal pool fairy shrimp (Branchinecta lynchi).

No large branchiopods, including listed species, were detected within these features.

The Study Area includes two portions of the MDP Line E Project (Project) alignment in the northwest and southeast. The proposed Project alignment will extend through the San Jacinto Commerce Center Specific Plan (SJCCSP) property, formerly named the Villages at San Jacinto Ms. Stacey Love

Project, which GLA has surveyed separately. The Project is generally bounded by Ramona Expressway and agricultural fields to the north, the San Jacinto Reservoir, agricultural fields, and the SJCCSP property to the east and south, agricultural fields, dairy farms, and Warren Road to the west. Universal Transverse Mercator (UTM) coordinates approximately corresponding to the Study Area are 499535 mE and 3741019 mN.

The wet season survey area consists of road ruts, riparian areas, and agricultural fields. The road ruts were unvegetated. The agricultural fields were either bare and tilled or planted with watermelon. Feature E-1 was partially vegetated with weedy species including non-native species including fivehorn smotherweed (Bassia hyssopifolia), perennial pepperweed (Lepidium latifolium), red brome (Bromus madritensis ssp. rubens), foxtail barley (Hordeum murinum), , Russian thistle (Salsola tragus), and alkali mallow (Malvella leprosa) Exhibit 3 depicts the wet season fairy shrimp survey area.

II. METHODOLOGY
GLA provided a written notification to commence wet season surveys to the U.S. Fish and Wildlife Service (USFWS), Carlsbad Field Office on November 9, 2023. Rain initiated hydrological monitoring on November 20, 2023. Storms in late December 2023 and early January 2024 initiated mapping of features. Sampling of Features E-2 and E-3 began on January 5, 2024. Feature E-1 began to sustain ponding after storms between January 19 – 23, 2024, with sampling beginning January 26, 2024. Features E-2 and E-3 dried and re-ponded several times and were completely dry on April 12, 2024. Feature E-1 remained ponded past 120 days with the last visit on May 22, 2024.

Specimens were placed into vials, with unique depression information, containing 95% ethanol solution. Specimens were identified through microscopy and using the “Key to California Fairy 1 USFWS. Survey Guidelines for the Listed Large Branchiopods, Revised: November 13, 2017.

SUBJECT: Dry Season Survey Results for Listed Branchiopods Conducted for the Master Drainage Plan (MDP) Line E Project, an Approximately 14,000 Linear-Foot Drainage Alignment, City of San Jacinto, Riverside County, California Dear Mr. Sattler:

This letter report documents the results of a dry season survey conducted by Glenn Lukos Associates, Inc. (GLA) for three depressional features at the Master Drainage Plan (MDP) Line E Project (Project), an Approximately 14,000 Linear-Foot Drainage Alignment located in the City of San Jacinto, Riverside County, California. GLA notified the U.S. Fish and Wildlife Service (USFWS) of the intent to perform the dry season surveys on September 3, 2024, with an email approval received on September 10, 2025. Dry season soil collection was conducted on September 20, 2024.

GLA biologist Chris Waterston (ESPER-2380694) performed the soil collection from the features, with assistance from GLA biologist Stephanie Cashin (PER11730977-1) and from GLA trainee Velvet Park (under supervision). Frank Wegscheider (TE-038716-4) processed the soil samples to determine cyst presence/absence.

I. SITE LOCATION AND DESCRIPTION
The Project site is located in the City of San Jacinto, Riverside County, California [Exhibit 1 – Regional Map] within Sections 19, 30, and unsectioned portions of Township 4 South, and Range 1 West and Section 24 of Township 4 South, and Range 2 West of the Lakeview, California USGS 7.5-minute quadrangle map [Exhibit 2 – Vicinity Map]. The Study Area includes two portions of the MDP Line E Project alignment in the northwest and southeast. The proposed Project alignment will extend through the San Jacinto Commerce Center Specific Plan (SJCCSP) property, formerly named the Villages at San Jacinto Project, which GLA has Mr. Jess Sattler

surveyed separately. The Project is generally bounded by Ramona Expressway and agricultural fields to the north, the San Jacinto Reservoir, agricultural fields, and the SJCCSP property to the east and south, agricultural fields, dairy farms, and Warren Road to the west. Universal Transverse Mercator (UTM) coordinates approximately corresponding to the Study Area are 499535 mE and 3741019 mN [Exhibit 3 – Fairy Shrimp Survey Area Map].

II. DESCRIPTION OF THE DEPRESSIONAL FEATURES
A total of three ponded features were included for dry season soil sampling. The features were characterized as unvegetated or vegetated. Unvegetated features included road ruts. The vegetated feature included an agricultural field basin.

Unvegetated (Road Ruts, Dirt Parking Areas, and Agricultural Fields) Of the three features included in dry season soil sampling, two features were described as road ruts (E-2 and E-3) which were unvegetated.

Vegetated (Agricultural and Roadside Ditches and Basins) Of the three features included in dry season soil sampling, one feature can be described as an agricultural basin (Pool E-1) that supported at least some vegetation. The basin included weedy annual species including five-hook bassia (Bassia hyssopifolia), stinknet (Oncosiphon piluliferum), Russian thistle (Salsola tragus), lamb’s quarters (Chenopodium album), cheeseweed (Malva parviflora), black mustard (Brassica nigra), and annual brome grasses (Bromus sp.).

III. METHODOLOGY
A. Soil Collection
Soil sample collection and processing followed the USFWS Survey Guidelines for the Listed Large Branchiopods, November 13, 2017 (USFWS 2017). Soil sample collection was conducted by GLA biologist Chris Waterston with assistance from Stephanie Cashin; and GLA biologist Velvet Park (under supervision) on September 20, 2024.

The number of samples collected for the ponded features is summarized in Table 1 below, which follows the Table 1 - Soil Sample Summary in the USFWS 2017 Survey Guidelines. Soil subsampling locations were distributed in a grid pattern to cover the entire feature with targeted Mr. Jess Sattler

B. Soil Processing
Soil analyses were conducted by USFWS-approved branchiopod biologist Frank Wegscheider.

Soil samples were placed into a one-gallon plastic container and allowed to pre-soak in water.

The resulting slurry was slowly poured into a graded set of stacked U.S. standard 8-inch soil sieves (710, 300, and 150 micron), while concurrently being gently washed with flowing water.

Water was directed through the samples for a time period sufficient to wash all of the resting eggs (cysts) into the 150-micron sieve. Soil remaining in the 150-micron and 300-micron sieves was used for analysis. The Project site lies outside of the currently documented range of the federally endangered vernal pool tadpole shrimp (Lepidurus packardi), which is endemic to California’s Central Valley (Rogers, 2001); therefore, it was not necessary to examine the 300- micron samples. Nonetheless, the 300-micron samples were examined for the presence of Cladoceran Ephippia. To facilitate the analyses, the 150-micron samples were transferred to a 150 ml beaker, whereupon the organic components were thrice-decanted. The remaining organic contents were then examined under a Celestron dissecting microscope at 10-30X for the presence of Anostracan cysts.

IV. RESULTS OF DRY SEASON SURVEY
A total of three features were sampled during the 2024 dry season surveys. No cysts of the genus Branchinecta or Streptocephalus, including listed species, were identified from the three features. No cyst culturing was necessary as no cysts were detected during processing. No listed species were detected. Table 2 includes the results of 2024 dry season fairy shrimp soil analysis.

Dear Ms. Love:

This letter report summarizes the methodology and findings of presence/absence surveys for the federally listed endangered southwestern willow flycatcher (Empidonax traillii extimus) (“SWFL”) conducted by Glenn Lukos Associates, Inc. (GLA) within the above referenced property located in the City of San Jacinto, Riverside County, California.

SWFL surveys were conducted from May 20 through July 3, 2024, in all areas of suitable habitat in accordance with U.S. Fish and Wildlife Service (USFWS) guidelines. The SWFL was not detected during the focused surveys. In addition, three least Bell’s vireo (Vireo bellii pusillus) “LBV” territories were detected onsite during the focused surveys.

1.0 INTRODUCTION
Southwestern Willow Flycatcher (SWFL)
The SWFL is a small, migratory songbird, which inhabits riparian habitats throughout southern California and is one of four subspecies of willow flycatcher (WIFL) currently recognized. It was officially designated as a state-endangered species on January 2, 1991, and federally designated as endangered on March 29, 1995. The SWFL measures about 5.75 inches (15 cm) in length and weighs only about 0.4 ounces (12 g). Overall, it is roughly the size of a small sparrow.

Both sexes look alike. Its appearance is overall greenish or brownish gray above, with a white throat that contrasts with a pale olive breast. The belly is pale yellow. Two white wing bars are visible, but the eye ring is faint or absent. The upper mandible is dark and the lower mandible light (USGS). It closely resembles the other races of willow flycatcher, and several other species of the Empidonax genus, particularly the closely related Alder flycatcher (Empidonax alnorum).

The SWFL breeds in relatively dense riparian habitats in all or parts of seven southwestern states, from near sea level to over 2,000 m (6,100 ft). More specifically, the SWFL breeds in riparian habitats along rivers, streams, or other wetlands, where relatively dense growths of trees and shrubs are established, near or adjacent to surface water or underlain by saturated soil (McCabe 1991). Common tree and shrub species comprising nesting habitat include willow (Salix sp.), boxelder (Acer negundo), tamarisk (Tamarix ramosissima), and Russian olive (Eleagnus angustifolia) (USFWS 2002).

Habitat characteristics such as plant species composition, size and shape of habitat patch, canopy structure, vegetation height, and vegetation density vary across the subspecies range. However, regardless of the plant species composition or height, occupied sites usually consist of dense vegetation in the patch interior, or an aggregate of dense patches interspersed with openings. In most cases this dense vegetation occurs within the first 3-4 m (10-13 ft) above ground. These dense patches are often interspersed with small openings, open water or marsh, or shorter/sparser vegetation creating a mosaic that is not uniformly dense (USFWS 2002). The SWFL winters in Mexico and Central America and northern South America (Phillips 1948, Gorsiki 1969, McCabe 1991, Koronkiewicz et al. 1998, Unitt 1999).

3.0 METHODOLOGY
Surveys for the SWFL were conducted in accordance with the 2010 U.S. Fish and Wildlife Service (USFWS) guidelines1, which stipulate that five surveys (divided into three survey periods) shall be conducted in all areas of suitable habitat. One survey was conducted during the first survey period (May 15 to May 31). Two surveys were conducted during the second survey period (June 1 to June 24), and two surveys were conducted during the third survey period (June 25 to July 17). GLA biologist Jeff Ahrens (TE 052159-6) conducted SWFL surveys on May 20, June 11, June 21, June 27, and July 3, 2024. Mr. Ahrens was accompanied by GLA biologist Chris Waterston (non-permitted) on June 27, 2024.

All surveys were conducted during the morning hours and were completed before 10:45 A.M.

No surveys were conducted during extreme weather conditions (i.e., winds exceeding 15 miles per hour, rain, or temperatures in excess of 95ºF). All areas of suitable habitat were surveyed on foot by walking slowly and methodically. Taped vocalizations primarily using the WIFL’s main contact call “fitz-bew” were used to elicit responses from WIFLs that might be present on site.

The detection of WIFLs on site was based on both sight and call.

Weather conditions during the SWFL surveys was conducive to a high level of bird activity.

Temperatures ranged from approximately 52 degrees Fahrenheit to 90 degrees Fahrenheit. Wind speeds ranged from 1-5 miles per hour during the surveys. Table 1 summarizes the survey dates and weather information for each survey date.

4.0 RESULTS
The SWFL was not detected on site during the focused surveys. GLA biologists detected three least Bell’s vireo (Vireo bellii pusillus; LBV) territories on site during the focused surveys.

Based on observed behavior, all three LBV territories appeared to be paired and nesting. The brown-headed cowbird (Molothrus ater) was detected on site and is a known nest parasite of the LBV and other riparian bird species.

Bird commonly observed during the focused surveys included the following: song sparrow (Melospiza melodia), mourning dove (Zenaida macroura), bushtit (Psaltriparus minimus), Nuttall’s woodpecker (Picoides nuttallii), Anna’s hummingbird (Calypte anna), common yellowthroat (Geothlypis trichas), house finch (Carpodacus mexicanus), lesser goldfinch (Spinus psaltria), black phoebe (Sayornis nigricans), Allen’s hummingbird (Selasphorus sasin), northern mockingbird (Mimus polyglottos) and house wren (Troglodytes aedon). An avian compendium is included in Appendix A.

Data sheets and an avian compendium listing all avian species detected during the focused surveys is included at the end of this report. Exhibits 3 and 4 depict the survey area and LBV locations on an aerial map and topographic map, respectively.

I certify that the information in this survey report and attached exhibits fully and accurately represents my work.

Good morning,
The U.S. Fish and Wildlife Service and the California Department of Fish and Wildlife, hereafter referred to jointly as the Wildlife Agencies, have reviewed the revised Determination of Biologically Equivalent or Superior Preservation (DBESP) for the San Jacinto Valley Master Drainage Plan Line E Project (Project), which we received from the City of San Jacinto on February 23, 2026 with our review and comment period ending on 4/24/2026.

The Wildlife Agencies appreciate the efforts in addressing our comments and providing a comparison of functions and values presented in the revised DBESP. We have reviewed the revised DBESP (dated January 2026), and we agree that the Project’s assessment of the onsite impacts (4.03 acre of permanent impacts associated with Ditches A, B, D, E, F, and Drainage A area) to riparian/riverine resources and the associated mitigation strategy would be biologically equivalent or superior to a complete preservation alternative.

Please condition the Project to provide a Habitat and Mitigation and Monitoring Plan (HMMP) to the Wildlife Agencies for review and approval for the restoration of 8.06 acres riparian/riverine mitigation area at least 60 days prior to the initiation of project activities.

We have no further comments to submit to the City of San Jacinto on the DBESP. This concludes our review of the revised DBESP for the San Jacinto Valley Master Drainage Plan Line E Project.

SUBJECT: Results of Focused Surveys for Crotch’s Bumble Bee Conducted for the MDP Line E Project, an Approximately 14,000 Linear-Foot Alignment in the City of San Jacinto, Riverside County, California
Dear Ms. Standerfer:

This letter report documents the results of focused Crotch’s bumble bee (Bombus crotchii; CBB) surveys conducted by Glenn Lukos Associates (GLA) for the MDP Line E Project. The CBB surveys were conducted in accordance with CDFW’s 2023 Survey Considerations for California Endangered Species Act (CESA) Candidate Bumble Bee Species. The CBB was not detected onsite.

1.0 SITE LOCATION
The MDP Line E Project (Project site) is located in the City of San Jacinto, Riverside County, California [Exhibit 1 – Regional Map] within unsectioned portions of Township 4 South, and Range 1 West of the Lakeview and San Jacinto, California USGS 7.5-minute quadrangle maps [Exhibit 2 – Vicinity Map]. The Project site is generally bounded by the San Jacinto Reservoir to the south, North Sanderson Avenue to the east and west, and Ramona Expressway to the north.

Exhibit 3 identifies the Project site. Specifically, the Universal Transverse Mercator (UTM) coordinates corresponding to the site are 499923.20 mE and 3740091.36 mN.

2.0 EXISTING CONDITIONS
The Project site is flat and predominantly supports active agricultural fields that are rotated regulary, and therefore the lands are dominated by plants associated with crop areas as well as Stephanie Standerfer
Albert A. Webb Associates
August 14, 2025

Page 2 ends

non-native vegetation associated with disturbed/ruderal areas. At the time of the survey some fields were fallow and some fields were planted with watermelon (Citrullus lanatus).

The 120.33-acre Project site consists of 94.41 acres of agricultural fields, 11.92 acres of annual brome grasslands, 10.43 acres of disturbed and developed areas, 0.03 acre of eucalyptus groves, and 3.54 acres of perennial pepperweed-prickly lettuce patches. Exhibit 3 provides an aerial image of the site, including the property boundary, which represents the CBB Survey Area.

Site photographs depicting the Project site are included in Exhibit 4.

3.0 METHODOLOGY
GLA biologists Jeff Ahrens, Stephanie Cashin and Ian Rhodes performed focused foraging surveys for the CBB in suitable habitat areas of the Project during the 2025 survey period. All three biologists are familiar with bumble bee natural history, bumble bee species identification and have detected the CBB on numerous sites throughout southern California. In addition, Ms.

Cashin (S-202690004-20273-001) holds a Scientific Collecting Permit (SCP) and a Section 2081(a) permit authorizing capture and release of CESA Candidate and/or TVPICP List bumble bees, including CBB.

Surveys generally followed the methods described by CDFW (2023) in Survey Considerations for California Endangered Species Act (CESA) Candidate Bumble Bee Species, which is not a mandated survey protocol, but instead “is intended to assist CDFW staff, project proponents, and consultants in developing, proposing, and evaluating survey protocols and surveys on a projectand site-specific basis.” The Survey Considerations provides an overview of and incorporates the methodology of established protocols (e.g. the USFWS rusty patched bumble bee protocol [USFWS 2019]), while allowing for modifications to the number and type of surveys based on factors including the size of a Project site, the vegetation alliances and the phenology of the floral resources present within those alliances, and the patchiness of suitable habitat. The Survey Considerations state that survey efforts should include multiple survey visits, with the timing of the visits determined on a project-by-project basis based on seasonality and when CBB utilization will most likely occur. The timing of the surveys may vary depending on the location, elevation, seasonal rainfall, average ambient air temperatures, and local seasonal weather conditions.

To increase probability of detecting foraging bumble bees, survey efforts at the Project site were conducted during peak bloom periods that encompass the queen flight season (February through March) as well as the Colony Active Period (April through August) when the queen, daughters, and males are generally active. Surveys were spaced at least two to four weeks apart throughout Stephanie Standerfer

the queen flight season and Colony Active Period to take advantage of the different blooming periods of floral resources.

The Project site supports both annual and perennial floral resources with the potential for utilization by CBB. The annual floral resources onsite (that CBB are known to use) consisted of common fiddleneck (Amsinckia intermedia), which was located primarily east of North Sanderson Avenue and along the edges of agricultural areas within the western portion of the site. Other annual species including smooth tarplant (Centromedia pungens ssp.), which have not been documented to be utilized by CBB were also surveyed. Perennial floral resources onsite with potential to be utilized by CBB was limited to alfalfa (Medicago sativa). Alfalfa is generally considered to be a perennial plant as it can live for more than two years, but at the Project site, alfalfa is generally grown as a short-season annual row crop that is rotated. Alfalfa within the Project site occurred west of North Sanderson Avenue. In addition to alfalfa, a small patch of branching phacelia (Phacelia ramosissima) was detected immediately offsite along the southeasternmost portion of the Project site within riparian habitat and was visually monitored when it was flowering as CBB is known to forage on it. GLA biologists surveyed the Project site in March, April, May, and June to capture the peak blooming periods of both annual and perennial floral resources.

Because of the patchy distribution of floral resources at the Project site, the location of which exhibited spatial and temporal variation depending on the particular species in bloom at any given time, each survey visit consisted of large meandering transects incorporating patches of floral resources across the landscape. During these transects, the surveyor spent approximately one person-hour of visual survey effort per three acres of suitable blooming habitat, which comprised multiple separate patches of suitable habitat totaling up to three acres rather than a single three-acre patch. In addition to floral resources, rodent burrows and other suitable features with potential to be used for nesting were examined for evidence of nesting activity including high levels of bee movements from the suspected nest location. The survey continued at a pace of approximately three acres of suitable habitat/blooming floral resources per survey hour as long as weather conditions were favorable for Bombus activity. Minimal time was spent in lesser quality habitat. All Bombus observations and floral resources used were recorded using GPS.

Photo vouchers of Bombus species were obtained by photographing bumble bees in situ from multiple angles with a professional level telephoto zoom lens and a camera body with a sensor capable of producing highly detailed images to ensure sufficient detail of identifying characteristics. Pursuant to the survey guidelines, the surveys were conducted between an hour after sunrise up until two hours before sunset, during times when weather conditions during the surveys are conducive to a high level of bee activity with temperatures generally 52-90 degrees Fahrenheit and wind less than seven miles per hour. Table 1 summarizes the CBB survey visits.

The results of the CBB surveys are documented in Section 3.0 of this report.

MANAGEMENT SUMMARY
The City of San Jacinto (City) proposes the construction of a three-mile-long corridor for the San Jacinto Master Drainage Plan Line E Project (Project). The Project involves development within Assessor’s Parcel Numbers 430-100-009, -012, -015, and -018; 430-130-043, -044, -073, -075, and -079; 436-010-002, -003, and -004; 436-030-001; and 436-170-001, -008, and -016 (approximately 1,920 acres), south of Ramona Expressway and east of Sanderson Avenue, in the city of San Jacinto, Riverside County, California. Under contract to the Albert A. Webb Associates, Applied EarthWorks, Inc. (Æ) conducted a cultural resource study of the Project in accordance with the California Environmental Quality Act (CEQA). The City is the lead agency for compliance with CEQA.

This report summarizes the methods and results of the cultural resource study, including a records search and literature review, communication with Native American Tribal representatives, and an archaeological survey of the Project area. The purpose of the study was to determine the potential for the proposed Project to impact historical resources eligible for or listed in the California Register of Historical Resources (CRHR).

The literature and records search at the Eastern Information Center of the California Historical Resources Information System indicated eight cultural resources have been documented within a

0.5-mile radius of the Project area. One of these previously identified cultural resources, a segment of the Colorado River Aqueduct, is located within the Project area.

Results of the Native American Heritage Commission (NAHC) Sacred Lands File search were negative for Native American cultural resources within the Project area. Per the NAHC’s request, Æ contacted 15 Native American individuals and organizations to elicit information on Native American resources within the Project area and received responses from representatives of seven tribes—Agua Caliente Band of Cahuilla Indians, Augustine Band of Cahuilla Indians, Cahuilla Band of Indians, Pechanga Band of Indians, Rincon Band of Luiseño Indians, San Manuel Band of Mission Indians, and Soboba Band of Luiseño Indians.

Æ archaeologist Andrew DeLeon completed an intensive pedestrian archaeological survey of the Project area on November 29, 2023. DeLeon revisited the location of the single subterranean cultural resource mapped within the Project area during the survey. No other cultural resources were identified within the Project area.

Although the Project area is disturbed and soil sensitivity appears low, the cultural resources identified adjacent to the Project area suggest some potential for subsurface archaeological deposits. In addition, it is Æ’s experience in this region that buried deposits can be found near the San Jacinto River. Therefore, Æ recommends archaeological monitoring during surface grubbing or clearing and initial grading within the Project area.

Field notes documenting the current study are on file at Æ’s Hemet office. A copy of this report will also be submitted to the Eastern Information Center.

Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 1 1 INTRODUCTION
The City of San Jacinto proposes the design and construction of a three-mile-long corridor for the San Jacinto Master Drainage Plan Line E Project (Project). The Project involves development within Assessor’s Parcel Numbers 430-100-009, -012, -015, and -018; 430-130-043, -044, -073, -075, and -079; 436-010-002, -003, and -004; 436-030-001; and 436-170-001, -008, and -016 (approximately 1,920 acres), south of Ramona Expressway and east of Sanderson Avenue, in the city of San Jacinto, Riverside County, California. Under contract to the Albert A. Webb Associates, Applied EarthWorks, Inc. (Æ) conducted a cultural resource study of the Project in accordance with the California Environmental Quality Act (CEQA). The City is the lead agency for compliance with CEQA.

Æ Principal Investigator M. Colleen Hamilton (M.A., Registered Professional Archaeologist [RPA] 12588) was responsible for overall quality control for the Project. Æ Senior Archaeologist Joan George (B.S., Registered Archaeologist 28093) served as project manager. The report was compiled and written by Jessica Cochran (B.A.). Fieldwork was conducted by Æ Associate Archaeologist Andrew DeLeon (M.A., RPA 17087).

1.1 PROJECT LOCATION AND DESCRIPTION
The Project is within the western portion of the city of San Jacinto in Riverside County (Figure 1-1). Specifically, the Project is mapped within Sections 19, 20, and 29, Township 4 South, Range 1 West of the San Bernardino Baseline and Meridian, and the San Jacinto Viejo land grant as shown on the U.S. Geological Survey (USGS) Lakeview and San Jacinto, California 7.5-minute topographic quadrangle maps (Figure 1-2). The elevation is approximately 1,467 feet above mean sea level.

The Project involves the design and construction of Line E as part of the San Jacinto Valley Master Drainage Plan (MDP), which aims to provide flood protection to the San Jacinto Commerce Center Specific Plan. The Project consists of a three-mile storm-drain channel that starts at the outlet channel of a joint flood control and confluence basin and ends at the existing Metropolitan Water District of Southern California (MWD) aqueduct right-of-way. A three-mile earthen channel with inclined side slopes at 4:1 and 20-foot-wide access roads on both sides will be constructed for stormwater to flow from south to north. Seven reinforced concrete box culverts, one of which will intersect Sanderson Avenue, will be installed. Berms will replace channelization at the southern end, while a concrete trapezoidal channel with inclined side slopes at 1.5:1 and up to 10 feet high will be built at the northern end. A bridge-type structure will be used to cross an existing MWD buried pipeline, Casa Loma Siphon No.1, to prevent adding loads to the existing pipeline. The maximum depth of ground disturbance during Project construction is not expected to exceed 20 feet.

1.2 REGULATORY CONTEXT

1.2.1 California Environmental Quality Act
The Project requires discretionary approval from the City and is therefore subject to the requirements of CEQA. The CEQA Statute and Guidelines directs lead agencies to determine whether a project will have a significant impact on historical resources. A cultural resource considered “historically significant” is considered a “historical resource,” if it is over 50 years of age, is included in a local register of historical resources, or is listed in or determined eligible for listing in the California Register of Historical Resources (CRHR) under any one of the following criteria (California Code of Regulations [CCR], Title 14, Section 15064.5):

1. Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage;

2. Is associated with the lives of persons important in our past;

3. Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or,

4. Has yielded, or may be likely to yield, information important in prehistory or history.

Compliance with CEQA’s cultural resource provisions typically involves several steps. Briefly, archival research and field surveys are needed, and identified cultural resources are inventoried and evaluated in prescribed ways. Prehistoric and historic archaeological sites as well as standing structures, buildings, and objects deemed historically significant and sufficiently intact (i.e., historical resources) must be considered in project planning and development.

A project with an effect that may cause a substantial adverse change in the significance of a historical resource is a project that may have a significant impact on the environment (14 CCR 15064.5[b]) and the lead agency is responsible for identifying potentially feasible measures to mitigate significant adverse changes in the significance of a historical resource (14 CCR 15064.5[b]4).

DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 5 2 SETTING
This chapter describes the prehistoric, ethnographic, and historic cultural setting of the Project area to provide a context for understanding the nature and significance of cultural resources identified within the region. Prehistorically, ethnographically, and historically, the nature and distribution of human activities in the region have been affected by such factors as topography and the availability of water and natural resources. Therefore, prior to a discussion of the cultural setting, the environmental setting of the area is summarized below.

2.1 ENVIRONMENTAL SETTING
The Project is in western Riverside County within the greater San Jacinto Valley. This area is in the Southern California batholith, a massive geological intrusion of granite that is part of the Peninsular Range formed in the late Cretaceous and uplifted in the early Tertiary. This mountain range extends from the San Gabriel Mountains to southern Baja Mexico. The physiography of the province is characterized by three northwest-trending mountainous regions composed of stable crustal blocks, separated by active fault zones, including (from east to west) the San Jacinto Mountains, the Perris Block, and the Santa Ana Mountains (Morton et al. 2006). The San Jacinto and Elsinore fault zones separate the three regions. The Project area is within the Perris Block, which consists of bedrock highlands and isolated hills separated by alluvium-filled valleys.

The primary drainage in the San Jacinto Valley is the San Jacinto River, the headwaters of which are in the San Jacinto Mountains; a portion of this river flows through the Project area and in the past, would have meandered across or near the Project area. The river flows northwesterly through the San Jacinto Valley and then west and southwest until it empties into Lake Elsinore, a sink in the Elsinore fault zone. Levees built between 1919 and 1939 altered the course of the river, shifting it as much as a mile south of its historic course. Prior to historic hydrological modifications, the San Jacinto River flowed perennially only in the eastern portion of the valley; during the wet season, however, the river flowed farther than today, collecting in the northern part of the valley (about 5 miles northwest of the Project) in an elongate depression forming a shallow, ephemeral lake now known as Mystic Lake (Morton 1977; Whitney 1982). Overflow from the lake drained to the southwest, eventually reaching Lake Elsinore. Because the lake existed before 1895, which predates groundwater withdrawal in the valley, Morton (1977) inferred that the depression is of tectonic origin.

Soils in the Project area, as mapped by the U.S. Department of Agriculture Natural Resources Conservation Service, include four soil series. The Chino and Grangeville soils are Mollisols, Dello soils are Entisols, and Traver soils are Alfisols. Mollisols are a taxonomic order of soils that consist mostly of minerals with a fertile surface horizon found extensively in the North American plains. Entisols are a taxonomic order of soils that consist mostly of minerals and are not in place long enough to form diagnostic horizons. Alfisols are soils that typically retain water DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 6 well for 3 months of the year during warm seasons, which fosters sufficient plant growth (Soil Survey Staff 1999b).

Chino soils are poorly drained silt loams and silty clay loams that formed in alluvium derived from granitic rocks (Soil Survey Staff 2020). Dello soils are very deep and poorly drained soils that formed in alluvium from granitic rock (Soil Survey Staff 1990). Grangeville soils are very deep and poorly drained soils that formed in moderately coarse-textured alluvium from granitic rock (Soil Survey Staff 1999a). Traver soils are moderately well to poorly drained soils that formed in alluvium derived from granitic bedrock (Soil Survey Staff 2003).

Considering the presence of each soil series and the disturbed nature of the Project area, the archaeological sensitivity is low. While the Chino soil contains well-defined A and C horizons, the integrity of the deposits is questionable because of agricultural disturbances. The Dello, Grangeville, and Traver soils are less defined. Furthermore, none of the soil series contains buried A (Ab) horizons that typically indicate the potential for buried archaeological deposits.

2.2 PREHISTORIC SETTING
The prehistory of inland Southern California is less thoroughly understood than in the adjacent desert and coastal regions. This is partially a result of historic circumstances, such as ease of access, the location of universities, and public versus private land ownership, and partly due to the nature of archaeological research in these interior valleys and mountains of Southern California (Goldberg and Arnold 1988). In the absence of absolute chronological indicators for inland sites, researchers generally employ typological cross-dating from either coastal or desert sequences, often as the sole means for assigning age to archaeological sites within the interior valleys, including the Project area.

Two large reservoir projects, Perris Reservoir (O’Connell et al. 1974) and Eastside Reservoir Project (ESRP) (Goldberg et al. 2001), generated large data sets to provide a basis for resolving some of these regional problems. It is difficult to extrapolate the geographic extent of the prehistoric cultural patterns discerned from excavations at these two reservoirs, which are 12 miles apart in central western Riverside County. The ESRP is approximately 7 miles south of the Project, and it is almost certain that prehistoric patterns are like those discerned for the ESRP studies.

This discussion of the Project’s prehistoric cultural setting is drawn from the cultural sequence developed for the ESRP. This chronology was based first on artifact cross-dating, and then refined with radiocarbon and obsidian hydration dates (Onken and Horne 2001; Robinson 1998, 2001); however, the ESRP chronology draws heavily on a cultural sequence defined by Warren (1984) for Southern California, which is based largely on archaeological work conducted in the Colorado and Mojave deserts. Because Warren’s chronology used period names that suggest links to the Mojave, these were replaced in the ESRP chronology by value-neutral terms.

Because no sites dating to the Paleoindian Period (circa 12,000–9500 before present [B.P.]) have been documented within the region, the discussion below begins with the Early Archaic Period.

DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 7

2.2.1 Early Archaic Period (circa 9500–7000 B.P.)
During this period, the environment of the interior deserts was more favorable for human occupation than the cismontane valleys of Southern California, where the Project is located.

Populations in the interior valleys would have been tethered to the few reliable, drought-resistant water sources such as Lake Elsinore, Mystic Lake, and possibly the Cajalco Basin. In general, small, highly mobile groups traveled widely, using highly portable tool kits to procure and process critical resources, with brief and anticipated intervals of seasonal sedentism near predictable water locations. Due to isolated locations where the conditions for occupation were met, Early Archaic Period sites are rare compared to later periods of prehistory (Goldberg et al. 2001; Grenda 1997; Horne and McDougall 2008; McDougall 1995).

2.2.2 Middle Archaic Period (circa 7000–4000 B.P.)
A gradual transition from wet pluvial conditions to arid desert conditions during the Early Holocene marks the transition to the Middle Archaic Period. Middle Archaic Period sites in Southern California include two in the ESRP, one at Lake Elsinore, the Stahl Site in Owens Valley, desert sites in Death Valley, Salt Springs, and at Pinto Basin in Joshua Tree National Park. Middle Archaic Period sites are associated with the margins of pluvial lakes and with nowextinct springs. Pinto-series projectile points, a type of basally notched or bifurcate base dart point, are the most distinctive artifact type of this period (Justice 2002). Other artifacts found at Middle Archaic Period sites include leaf-shaped bifacial knives, split cobble choppers and scrapers, scraper-planes, and small milling slabs and manos. With a few exceptions in the ESRP area and the Stahl Site, most sites of this age are small surface deposits of lithic artifacts, suggestive of temporary and perhaps seasonal occupation by small groups of people.

2.2.3 Late Archaic Period (circa 4000–1500 B.P.)
The Late Archaic Period was one of cultural intensification coinciding with the Little Pluvial, a period when increased moisture allowed for more extensive occupation of the region. Sedentism likely increased during this period, with large occupation sites located adjacent to permanent water sources such as perennial springs and streams. Projectile points diagnostic of this period include Humboldt, Gypsum, and Elko-series dart points (Warren 1984), although Rose Spring arrow points appeared late within this period in the deserts. The mortar and pestle, used for processing acorns and hard seeds, also first appeared. A warming and drying trend began around 2100 B.P., leading to intensification of use of certain resources (Goldberg et al. 2001).

2.2.4 Saratoga Springs Period (circa 1500–750 B.P.)
Occupants of the region continued to adapt to the arid environment in the deserts (Warren 1984).

Lake Cahuilla likely refilled the Coachella Valley around 1450 B.P. and was the focus of exploitation of fish and wetland resources. Occupation around large local water sources declined as these dried, however, and people became tethered to springs (Goldberg et al. 2001). Cultural trends continued from the Late Archaic Period, as Saratoga Springs projectile points, also associated with early use of the bow and arrow, appeared. The sparse assemblages found within the region obscure the timing of local adoption of the bow and arrow (Goldberg et al. 2001).

Shoshonean language speakers likely moved into Southern California at this time. Brown and Buff Ware pottery first appeared on the lower Colorado River at about 1200 B.P. and started to DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 8 diffuse across the California deserts by about 1100 B.P. (Moratto 1984). The warmer and drier Medieval Warm Period set in throughout the Southwest by about 1060 B.P. (Stine 1994; Warren 1984) and led to the withdrawal of Native American populations from marginal desert areas.

2.2.5 Late Prehistoric Period (circa 750–410 B.P.)
A period of lower temperatures and increased precipitation known as the Little Ice Age resulted in increased resource productivity in the region and subsequent population increase. Cottonwood Triangular points appear in inland assemblages and Obsidian Butte glass became much more common (Goldberg et al. 2001). Lake Cahuilla began to recede (Waters 1983), and the large Patayan populations occupying its shores moved westward to areas such as Anza Borrego, Coyote Canyon, the Upper Coachella Valley, the Little San Bernardino Mountains, and the San Jacinto Plain (Wilke 1976). The final recession of Lake Cahuilla, which had occurred by approximately 400 B.P., resulted in a population shift away from the lakebed into the Peninsular Ranges to the west and the Colorado River regions to the east.

2.2.6 Protohistoric Period (circa 410–180 B.P.)
Sedentism intensified during the Protohistoric Period. Increased hunting with bow and arrow and widespread exploitation of acorns, other hard nuts, and berries (indicated by the abundance of mortars and pestles) provided reliable and storable food resources. Reliable food sources likely prompted the establishment of small, completely sedentary villages with resource catchment areas around them (True 1966, 1970). Ceramic technology first appeared in the region around 350 B.P. Cottonwood Triangular points were supplemented by Desert Side-notched points. This period ended in 1769 A.D. when Spanish settlement began in Upper California.

2.3 ETHNOGRAPHIC SETTING
This description of the ethnographic setting is based on information passed down from tribal elders; found in published academic works in the areas of anthropology, history, and ethnohistory; and provided in recorded ethnographic and linguistic accounts (cf., Kroeber 1925; Smith and Freers 1994; Strong 1929; Vane 2000). The Project lies within the ancestral cultural territory of the Luiseño Native American cultural group, and more specifically, within the traditional territory of the Soboba Band of Luiseño Indians. However, the area also may have been occupied by the Cahuilla Native American cultural group due to population shifts in the historic era (Bean 1978). Both tribes speak a language of the Takic branch of the Shoshonean family, part of the larger Uto-Aztecan language stock.

Luiseño territory in ethnographic times encompassed a stretch of the California coast and included most of the drainage of the San Luis Rey and Santa Margarita rivers. Inland, Luiseño territory extended south from Santiago Peak, including the Elsinore and Temecula valleys, and extended farther south to Mount Palomar and the San Jose Valley, then west to the coast at Agua Hedionda Creek. The coastal territory of the Luiseño extended north to near San Mateo Creek in Orange County (Bean 1978). Elders of the Pechanga Band of Luiseño Indians add that the Temecula/Pechanga people had usage/gathering rights to an area extending from Rawson Canyon on the east to Lake Mathews (modern) on the northwest, down Temescal Canyon to Temecula, eastward to Aguanga, and then along the crest of the Cahuilla Range back to Rawson Canyon.

DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 9 Ethnographically, Cahuilla territory spanned from the summit of the San Bernardino Mountains in the north to Borrego Springs and the Chocolate Mountains in the south, a portion of the Colorado Desert west of Orocopia Mountain to the east, the San Jacinto Plain as far as Riverside, and the eastern slopes of Palomar Mountain to the west (Bean 1978).

2.3.1 Ethnographic Lifeways of the Soboba Band of Luiseño Native Americans and the Cahuilla Native Americans
Prior to the Mission Period (before circa 1769), each Luiseño village was organized as a clan tribelet: a group of people patrilineally related who owned an area in common and who were politically and economically autonomous from neighboring groups. The entire social structure is obscure. It does not appear that they were organized into exogamous moieties such as were the Cahuilla (Strong 1929:291).

The Cahuilla had nonpolitical, nonterritorial moieties that governed marriage patterns as well as patrilineal clans and lineages. The words for these moieties mean “Coyote” and “Wildcat.” In turn, the political-ritual-corporate units (clans) were composed of 3–10 lineages, distinctly different, named, and claiming a common genitor, with one lineage recognized as the founding lineage (Bean 1978; Bean and Vane 2001). Clans owned a large territory in which each lineage owned a village site and specific resource areas. Clan lineages cooperated in large communal subsistence activities (including animal drives, hunts, controlled burns) and in performing rituals.

The Luiseño and Cahuilla were, for the most part, hunters, collectors, and harvesters. Clans were apt to own land in valleys, foothill, and mountain areas, providing them with the resources of many different ecological niches. Individual lineages or families owned specific resource areas within the clan territory. Although any given village had access to only some of the necessary resources, briskly flourishing systems of trade and exchange gave them access to neighboring and distant resources. Rules that forbade marriage to anyone related within five generations or belonging to the same moiety ensured that everyone had relatives living in many ecozones; this was an important arrangement because relatives were invited to ceremonies. The ceremonial exchange of gifts at such events provided a way for drought-stricken groups to get food in return for treasure goods.

The Luiseño and Cahuilla, like other California Indians, understand the universe in terms of power, which they believed to be sentient and willful. In their view, power is the principal causative agent for all phenomena. Unusual natural phenomena are viewed as especially sacred, serving as the repositories of concentrations of power. Mountain tops are held sacred, as are unusual rock formations, springs, and streams. Rock art sites are sacred, having been the sites of ceremonies. Burial and cremation sites are also sacred, as are many other places of residual power. In addition, various birds, but especially eagles, condors, hawks, and other birds of prey and their symbolic representations, are revered as sacred beings of great power and were sometimes killed ritually and mourned in mortuary ceremonies similar to those for human elites.

For this reason, bird cremation sites are also sacred.

Because of these strong beliefs, rituals were (and continue to be) a constant factor in the life of Native American individuals. Some rituals were scheduled and routine (e.g., birth, puberty, death, mourning, and the eagle ritual and first rites), while others, such as the deer ceremony, DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 10 bird dance, enemy songs, and rain ritual, were sporadic and situationally performed (Bean 1978; Bean and Vane 2001:VII.A-3-10).

2.4 HISTORIC SETTING
The Spanish occupation of Alta California and the founding of the San Diego de Alcalá mission in San Diego occurred in 1769, resulting in compilation of written records. The following historic context of California was taken primarily from Clark and Smallwood (2015).

Exploration of the California coast in the sixteenth and seventeenth centuries was the basis for the Spanish claim to the region. In the eighteenth century, Spain recognized that to strengthen its claim, it would have to settle Alta California to preclude encroachment by the Russians and British traders from the north. Therefore, in the latter half of the eighteenth century, Spain and the Franciscan Order founded a series of 3 presidios, or military camps, and 21 missions along the California coast, beginning at San Diego in 1769. The Spanish also carried out exploratory expeditions into the interior regions, including the Mojave Desert, to identify travel routes to the coast and to establish interior settlements.

With the signing of the Treaty of Guadalupe-Hidalgo on February 2, 1848, California had formally become an American territory, and 2 years later, on September 9, 1850, California became the thirty-first state in the Union. Between those 2 years came a large influx of eastern immigrants seeking their fortunes. The catalyst for this influx was James Marshall’s 1848 discovery of gold at Sutter’s Mill (Starr 2005), and the population and wealth in the early statehood years were concentrated in the northern part of the state. Ranching was the main occupation in the southern counties, providing meat and supplies to the north. The floods and drought of the 1860s brought that era to a close, and the completion of the transcontinental railroad in 1869 opened California to agricultural settlement.

Southern California was promoted as an ideal agricultural area, with fertile soil and a mild climate. Reports on California painted beautiful pictures that appealed to both Americans and Europeans alike. There were three land booms tied to railroad expansion: (1) after the transcontinental railroad was completed, enabling easy travel to California; (2) in the late 1870s after the Southern Pacific Railroad was completed; and (3) in 1886–1888, when the Santa Fe Railway transcontinental line was completed. Competition between these lines incited a rate war, and both tourists and potential settlers took advantage of the low fares to come to California (Lech 2004:222).

2.4.1 Local History
As the railroads spurred land development, local population increased, and a successful movement to form a new county followed. In 1893, Riverside County was formed from parts of San Diego and San Bernardino counties, with the city of Riverside as the county seat. San Jacinto was originally part of San Diego County.

As early as 1867, the Estudillo family began to sell off some of their land grant in the San Jacinto Valley to new arrivals (Brigandi 2001). By 1868, a school district was needed to educate numerous children. Around the same time, Procco Akimo (a Russian immigrant) opened the first local store, around which grew the first settlement named San Jacinto. In May 1870, a new mail DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 11 route established between San Bernardino and San Diego passed through the valley (Brigandi 2001).

In 1883, San Jacinto was laid out on 160 acres owned by the San Jacinto Land Association. By 1886, San Jacinto had a population of 250 and the town boasted a two-story schoolhouse, a large hotel, and a downtown commercial block. Bacon & Ashenfelter (the largest construction firm) advertised the services of architects, contractors, and builders, with plans and specifications furnished, as well as brick contractors. There were four masons and plasterers in town, two brickyards, and a planing mill. No saloons were allowed in the town (Lech 2004). The leading families built fashionable houses, the most prominent of which was that of Francisco Estudillo.

H. C. Ashenfelter (“Harry”) went into real estate, among other concerns; he was also a mine owner, with interests in the community of Strawberry (now Idyllwild). Lech (2004) provided the following information from an article in the San Jacinto Weekly Register published on March 17, 1889:

We all know Harry, as he has been identified with the business interests of San Jacinto ever since it started and from time to time has been connected with a number of very important business transactions which have been stepping stones toward the present and prospective future of our thriving little town.

The railroad arrived in town on the same day San Jacinto became incorporated as a city: April 9, 1888. To take advantage of the railroad for agricultural shipping, Francisco Estudillo built a large brick warehouse northeast of the depot, where space was available to local farmers (Brigandi 2001). He also built a livery stable in town, and on February 9, 1893, the San Jacinto Register acknowledged that he had done “his full share in aiding the growth of the town” (Brigandi 2001:12). The town grew and prospered from its role as a railroad terminus, as the station was used to transport agricultural products from the valley and lumber from the San Jacinto Mountains.

All sorts of agricultural endeavors were encouraged in the 1880s. As wells were drilled on ranches west of town, more land was put into alfalfa. Notices of new arrivals and land transfers were published in the newspaper, as was every new house and business built.

The San Jacinto Valley has been important in the production of agricultural products in Southern California for more than the last 100 years. As reliable sources of water became available during this period, farms were founded, and settlers raised a variety of crops and tended domestic animals. In this rural landscape, traditional farm buildings were constructed, occupied, and used to store agricultural products and to house livestock. As some of the farming enterprises declined, the buildings were torn down or allowed to deteriorate, leaving only traces of their physical remains. Landscape features, such as apricot orchards that once dominated the countryside, have been removed. Further loss has resulted from increasing suburban construction in the last 25 years, and this trend continued to accelerate. Nonetheless, the valley is still largely rural, with remnant farms intermixed with modern housing developments. Although some farms and rural homesteads still flourish, others have been converted to business enterprises or have disappeared completely.

Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 12 3 CULTURAL LITERATURE AND RECORDS SEARCH
On March 8, 2023, prior to the field survey of the Project area, Æ engaged the Eastern Information Center (EIC), the branch of the California Historical Resource Information System housed at the University of California, Riverside, to complete a literature and records search. The objective of this records search was to determine whether any prehistoric or historic cultural resources had been recorded previously within the Project area and a 0.5-mile search radius of the proposed Project.

3.1 RECORDS SEARCH RESULTS
Results of the records search indicated 43 cultural resource studies have been conducted previously within the 0.5-mile search radius (Table 3-1). Eighteen of the previous studies involved a portion of the Project area. As a result, approximately 40 percent of the Project area has been studied previously.

The records search resulted in the identification of a total of eight previously recorded cultural resources within the 0.5-mile search radius. Six of the resources are archaeological: three prehistoric isolated artifacts, one historic refuse scatter, and two irrigation wells. In addition, two built-environment resources were identified within the 0.5-mile search radius (Table 3-2). One of the cultural resources, the Colorado River Aqueduct, is documented within the Project area. This resource is described in further detail below.

3.1.1 CA-RIV-6726H/33-011265—Colorado River Aqueduct
Originally recorded by Goodman and Neves (2000), CA-RIV-6726H consists of the Colorado River Aqueduct and its various segments, constructed in the early 1930s. The aqueduct begins at the Whitsett Intake Pumping Plant in Lake Havasu California and extends approximately DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 16 242 miles to its terminus at Lake Mathews. The Colorado River Aqueduct has been recommended as eligible for listing in the National Register of Historic Places (NRHP) under Criteria A, C, and D (Beedle 2008:5). Furthermore, a portion of the aqueduct was determined eligible for the NRHP with concurrence from the State Historic Preservation Officer.

3.2 HISTORIC MAP REVIEW
A series of historic maps were consulted to assess land use and development in the study area.

Several USGS topographic quadrangle maps were consulted: 1901 Elsinore 1:125,000, 1901 Southern California 1:125,000, 1942 Perris 1:62,500, 1953 and 1967 Lakeview 1:24,000.

Two historic roads that appear to be aligned with modern-day Ramona Expressway and Warren Road are visible on the 1901 Elsinore map north of the Project and continue to be displayed on the latest examined maps. The 1953 Lakeview map shows a segment of the Colorado River Aqueduct in the northwestern portion of the Project, along with a component of the Colorado River Aqueduct and three structures within the agricultural fields in the southeastern Project area. The structures also appear in aerial photographs from 1966 to 1978, available online (historicaerials.com/viewer). The three structures on the southeastern corner of the Project area are no longer visible in imagery from 1985 and were likely demolished. All the maps exhibit the Colorado River Aqueduct tunnel north and south of the Project area. No other buildings, structures, or features of interest are shown in the Project area on any of the historic maps or photographs examined.

Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 17 4 NATIVE AMERICAN COMMUNICATION
Æ contacted the Native American Heritage Commission (NAHC) on March 8, 2023, for a review of their Sacred Lands File to determine if any known Native American cultural properties (e.g., traditional use or gathering areas, or places of religious or sacred activity) are present within or adjacent to the Project area. The NAHC responded on March 15, 2023, stating the Sacred Lands File search was completed with negative results. The NAHC requested that Æ contact Native American individuals and organizations to elicit information regarding cultural resource issues related to the proposed Project, if any.

Upon review of the Native American contact list, Æ narrowed the list to 15 individuals and organizations traditionally and culturally affiliated with the geographic area of the Project. Æ sent out Project scoping letters via email and U.S. Postal Service on December 8, 2023, describing the Project and asking these individuals and organizations for their input. Copies of the letters, the list of contacts, and received responses are included in Appendix A. Æ sent follow-up email correspondence on December 22, 2023, to the organizations who had not responded to the initial request on December 8, 2023.

Individuals/organizations contacted include:
• Reid Milanovich, Chairperson for the Agua Caliente Band of Cahuilla Indians • Amanda Vance, Chairperson of the Augustine Band of Cahuilla Indians • Doug Welmas, Chairperson of the Cabazon Band of Mission Indians • Daniel Salgado, Chairperson of the Cahuilla Band of Indians • Ray Chapparosa, Chairman of the Los Coyotes Band of Cahuilla and Cupeño Indians • Robert Martin, Chairperson for the Morongo Band of Mission Indians • Shasta Gaughen, Tribal Historic Preservation Officer for the Pala Band of Mission Indians
• Mark Macarro, Chairperson for the Pechanga Band of Indians • Manfred Scott, Acting Chairperson for the Quechan Tribe of the Fort Yuma Reservation
• Joseph Hamilton, Chairperson of the Ramona Band of Cahuilla • Bo Mazzetti, Chairperson for the Rincon Band of Luisen͂o Indians DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 18 • Jessica Mauck, Director of Cultural Resources for the San Manuel Band of Mission Indians
• Lovina Redner, Tribal Chair of the Santa Rosa Band of Cahuilla Indians • Isaiah Vivanco, Chairperson for the Soboba Band of Luiseño Indians • Cultural Committee of the Torres-Martinez Desert Cahuilla Indians As of January 12, 2024, Æ has received seven responses. • Because the Project falls within the Agua Caliente Band of Cahuilla Indians’ Traditional Use Area, the Tribe requested a copy of the records search, survey reports, and site records from the EIC, copies of any cultural resource documentation generated from the current Project, and shapefiles of the Project area. • The Augustine Band of Cahuilla Indians are unaware of any cultural resources that would be affected by the Project but wish to be contacted immediately if any resources are discovered during development.
• The Cahuilla Band of Indians are unaware of any cultural resources that would be affected by the Project but wish to be contacted immediately if any resources are discovered during development. However, since this Project is within the Cahuilla Band’s traditional land use area, they request to participate in monitoring once construction starts.
• The Pechanga Band of Indians requested consultation on the Project because part of the Project area is within a Traditional Cultural Property and nearly adjacent to a second Traditional Cultural Property. Therefore, the Tribe requests notification of Project start, copies of all applicable reports, government-to-government consultation with the lead agency, and monitoring by a Riverside County qualified archaeologist and Pechanga Tribal Monitor.
• The Rincon Band of Luiseño Indians has no additional information to provide, but they recommend that Æ directly contact the Soboba of Luiseño Indians as they are closer to the Project and may have pertinent information. • The San Manuel Band of Mission Indians stated that the Project is located outside of Serrano's ancestral territory and, therefore, San Manuel will not be requesting to receive consulting party status with the lead agency or to participate in the scoping, development, or review of documents created under legal and regulatory mandates. • The Soboba Band of Luiseño Indians stated that Project Line E is located within an area of high concern for Tribal Cultural Resources. Substantial information will be provided to the lead agency during consultation.

Complete responses from each contact are attached in Appendix A.

Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 19 5 METHODS AND RESULTS
This chapter details the methods and results of the intensive pedestrian survey of the Project area.

Portions of the Project were previously surveyed during initial phases of the Project.

Approximately 20 percent of the Project area was inaccessible during the current survey due mainly to dense tree and weed growth in various areas (Figure 5-1). The intensive survey was completed by Æ archaeologist Andrew DeLeon on November 29, 2023.

5.1 SURVEY METHODS
DeLeon began surveying on the northwestern portion of the Project area and proceeded south.

The survey was conducted in 15-meter transects oriented east–west, moving westward through the Project area. While surveying, DeLeon photographed the Project area at various locations to document its current condition. Any newly identified resources were to be photographed and mapped with an Arrow 100 global navigation satellite system receiving unit and iPad. DeLeon also visited the locations of the previously recorded cultural resource mapped within the Project area.

5.2 SURVEY RESULTS
The entire Project area is heavily disturbed, with the northwestern and southeastern portions being the most affected. In the northwestern portion, DeLeon encountered challenges due to heavy weed growth and loose dogs near the greenhouses on the western side, which prevented survey of the open field areas south of the Colorado River Aqueduct (CRA, 33-011265/ CA-RIV-6726H). However, DeLeon was able to conduct transects with 15-meter spacing north of the CRA. The northwestern portion of the Project area appeared to be disturbed entirely, primarily due to active facilities and agriculture. The ground visibility was poor, with only two percent visibility due to extensive grass coverage (Figure 5-2). The surface soil was a soft gray silt loam.

Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 21 Figure 5-2 Northwestern corner, facing south.

Almost all the area was disturbed in the southeastern portion of the Project, mainly due to active agriculture and occupied homestead property (Figure 5-3). The agricultural fields were visible on satellite imagery, indicating the extent of the disturbance. However, the southern half of the southeastern Project area contained densely forested areas of mainly eucalyptus, cottonwood, willow, palo verde trees, and Russian thistle, which made surveying on foot difficult.

Considering the inconsistent terrain, DeLeon focused on surveying open areas clear of dense vegetation. Only the southernmost extension of the southeastern Project area was accessible for on-foot surveying.

5.2.1 Previously Documented Resources
Upon completion of the survey, Æ confirmed the Colorado River Aqueduct (CA-RIV-6726H/ 33-011265) crosses through the Project area underground at two locations. This resource is outside the Project area’s vertical limits and, therefore, will not be impacted by construction of the Project.

DRAFT
Cultural Resource Study for the San Jacinto Master Drainage Plan Line E 23 6 MANAGEMENT RECOMMENDATIONS
Æ did not encounter any previously unrecorded cultural resources within the Project area during the intensive pedestrian survey. However, the previously recorded cultural resource within the Project area was revisited—segments of the Colorado River Aqueduct (33-011265/ CA-RIV-6726H). The Colorado River Aqueduct crosses the Project area underground. This resource is outside the Project’s vertical limits and, therefore, will not be impacted by the construction of the Project.

The entire Project area is highly disturbed on the surface by agricultural activity, road development, and addition of modern structures. Geological data indicate no Ab (buried) horizons for soil series mapped within the Project area. Although the Chino soil series contains well developed A and C horizons, the integrity of those deposits is questionable due to modern agricultural activities. Although the Project area is disturbed from agricultural activity and soil sensitivity appears low, previous prehistoric isolated finds and historic archaeological sites identified by the records search in the buffer for the current Project indicate a potential for subsurface deposits. In addition, it is Æ’s experience in this region that buried deposits can be found near the San Jacinto River. Therefore, Æ recommends archaeological monitoring during surface grubbing or clearing and initial grading within the Project area.

It should be noted that the Project falls within the traditional land use area of the Agua Caliente Band of Cahuilla Indians. The Augustine Band of Cahuilla Indians and the Cahuilla Band of Indians are unaware of any cultural resources that would be affected by the Project but request to be notified immediately if any resources are discovered during development. However, since this Project is within the Cahuilla Band’s traditional land use, they requested to participate in monitoring once construction begins. The Pechanga Band of Indians requested consultation on the Project, as part of the Project area is within a Traditional Cultural Property. The Rincon Band of Luiseño Indians has no additional information to provide, but they recommend that Æ directly contact Soboba of Luiseño Indians as they are closer to the Project and may have pertinent information. The San Manuel Band of Mission Indians will not participate as the Project is located outside of Serrano ancestral territory. The Soboba Band of Luiseño Indians stated that Project Line E is within an area of high concern for Tribal Cultural Resources. No further comments were received from the tribes after follow-up communication.

Finally, if the Project area is expanded to include areas not covered by this survey or other recent cultural resource studies, additional cultural resource studies may be required.

March 15, 2023
Andrew DeLeon
Applied EarthWorks, Inc.

Via Email to: [email protected]
Re: San Jacinto Master Drainage Plan Project, Riverside County Dear Mr. DeLeon:

A record search of the Native American Heritage Commission (NAHC) Sacred Lands File (SLF) was completed for the information you have submitted for the above referenced project. The results were negative. However, the absence of specific site information in the SLF does not indicate the absence of cultural resources in any project area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites.

Attached is a list of Native American tribes who may also have knowledge of cultural resources in the project area. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated; if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe. If a response has not been received within two weeks of notification, the Commission requests that you follow-up with a telephone call or email to ensure that the project information has been received.

If you receive notification of change of addresses and phone numbers from tribes, please notify me. With your assistance, we can assure that our lists contain current information.

If you have any questions or need additional information, please contact me at my email address: [email protected].

Sincerely,
Andrew Green
Cultural Resources Analyst

Re: Cultural Resource Assessment for the San Jacinto Master Drainage Plan Line E Project, City of San Jacinto, Riverside County, California
Dear Chairperson Amanda Vance:

On behalf of Albert A. Webb Associates, Applied EarthWorks, Inc. (Æ) is conducting a cultural resource study for the San Jacinto Master Drainage Plan Line E Project, City of San Jacinto, Riverside County, California (Project).

The Project involves construction of a 3-mile-long storm drain channel (Line E) which is an implement of the overall San Jacinto Master Drainage Plan. The Project is subject to the California Environmental Quality Act (CEQA) with the City of San Jacinto as the lead CEQA agency. The Project is located within Sections 18, 20, and 29 of Township 4 South, Range 1 West as indicated on the attached map. Specifically, the Project area is located south of Ramona Expressway and east of Sanderson Avenue.

Æ conducted a literature and records search review, which indicated 8 cultural resources within a 0.5-mile radius of the Project area. One of those resources (The Colorado River Aqueduct) is documented within the project area.

Æ was contracted to perform an archaeological survey of the Project area, which was completed on November 29, 2023. The project area consists primarily of active agricultural facilities, land, and a modern homestead. AE was able to reidentify the single subterranean cultural resource mapped within the Project area during the survey. No other cultural resources were identified within the Project area.

As part of the cultural resource assessment of the Project area, Æ requested a search of the Sacred Lands File by the Native American Heritage Commission (NAHC) on March 8, 2023. The NAHC responded on March 15, 2023, noting that Sacred Lands File search was completed with negative results. Should your records show that cultural properties exist within or near the Project area shown on the enclosed map, or if you have any concerns regarding Native American issues related to the overall Project, please contact me at (951) 766-2000 or via letter expressing your concerns. You may also e-mail me at [email protected]. If I do not hear from you within the next two weeks, I will contact you with a follow-up email or phone call.

Please be aware that your comments and concerns are very important to us, as well as to the successful completion of this Project. I look forward to hearing from you in the near future. Thank you, in advance, for taking the time to review this request.

Respectfully yours,

MANAGEMENT SUMMARY
Applied EarthWorks, Inc. (Æ), at the request of Albert A. Webb Associates, assessed the potential for impacts to significant paleontological resources for the San Jacinto Master Drainage Plan (MDP) Line E Project (Project) in the city of San Jacinto, Riverside County, California. The Project involves the construction of a 3-mile-long storm-drain channel as part of the MDP on approximately 1,920 acres of land in northern San Jacinto, which will provide flood protection to the San Jacinto Commerce Center Specific Plan. Æ prepared this Paleontological Resource Assessment (PRA) in partial satisfaction of California Environmental Quality Act (CEQA) requirements. The City of San Jacinto is the lead agency for CEQA compliance.

This PRA was completed from a combination of desktop studies and fieldwork. The desktop studies included a review of published and unpublished literature and maps, as well as museum records searches. The purpose of these studies was to identify the geologic units in the Project area and to determine whether previously recorded paleontological localities occur either within the Project area, or within the same geologic units nearby but outside the Project area. As a result of the desktop studies and fieldwork, Æ has determined that the Project area has High B Sensitivity based on Riverside County’s sensitivity rankings.

Æ recommends preparation of a Paleontological Resource Impact Mitigation Program (PRIMP) by a qualified professional paleontologist (Paleontological Principal Investigator, Project Paleontologist) as defined by mitigation paleontology industry standards and/or the Society of Vertebrate Paleontology. The PRIMP will specify the steps to be taken to mitigate impacts to paleontological resources. For instance, Worker’s Environmental Awareness Program training should be prepared prior to the start of Project-related ground disturbance and presented in person to all field personnel to describe the types of paleontological resources that may be found and the procedures to follow if any are encountered. The PRIMP also will include a monitoring plan that indicates where construction monitoring will be required and the frequency of required monitoring (i.e., full-time, spot-checks, etc.). to ensure adverse impacts to paleontological resources will be reduced to a less-than-significant level in accordance with CEQA.

Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 1 1 INTRODUCTION
Applied EarthWorks, Inc. (Æ), at the request of Albert A. Webb Associates, assessed the potential for impacts to significant paleontological resources for the San Jacinto Master Drainage Plan (MDP) Line E Project (Project) in the city of San Jacinto, Riverside County, California. Æ prepared this Paleontological Resource Assessment (PRA) in partial satisfaction of California Environmental Quality Act (CEQA) requirements. The City of San Jacinto (City) is the lead agency for CEQA compliance.

1.1 PROJECT DESCRIPTION
The Project is within the western portion of the city of San Jacinto in Riverside County (Figure 1-1). Specifically, the approximately 1,920-acre Project area is south-southwest of the intersection of Ramona Expressway and North Sanderson Avenue. The northwestern corner of the Project area is approximately 1 mile west of the intersection, and the southeastern corner borders and partially overlaps the east-northeastern side of the San Jacinto Reservoir approximately 1.7 miles south of the intersection. The Project area is mapped in Sections 18, 19, 20, and 29, and unsectioned areas of Township 4 South, Range 1 West, San Bernardino Baseline and Meridian, as shown on the U.S. Geological Survey (USGS) Lakeview and San Jacinto, CA,

7.5-minute topographic quadrangle maps (Figure 1-2).

The Project is a component of the MDP that involves development of a 3-mile-long storm-drain channel that will provide flood protection to the San Jacinto Commerce Center Specific Plan.

Storm water will flow from south to north, beginning from an outlet channel of a large joint flood-control and confluence basin at the southeastern terminus and ending at the existing Metropolitan Water District of Southern California aqueduct right-of-way at the northwestern terminus. The Project will involve construction of an earthen channel measuring 65 feet wide and up to 10 feet high, with side slopes inclined at 4:1 (horizontal:vertical), as well as several sloped rip-rap drops along the alignment. The Project also will include 20-foot-wide access roads on both sides of the channel along with seven 6- to 8-cell reinforced concrete box culverts. One of the culverts will intersect Sanderson Avenue, and the remaining culverts will intersect future roadways. The maximum anticipated depth of excavation for the Project is approximately 20 feet below ground surface (bgs).

1.2 PURPOSE OF INVESTIGATION
This PRA is designed to accomplish several goals: (1) identify the geologic units within the Project area and assess their paleontological resource potential; (2) determine whether the Project has the potential to adversely impact scientifically significant paleontological resources; (3) provide Project-specific management recommendations for paleontological resources, as necessary; and (4) demonstrate compliance with state laws and local regulations. Section 1.4 describes the ways in which this PRA meets the stated goals.

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 5 2 REGULATORY ENVIRONMENT
Paleontological resources (i.e., fossils) are considered nonrenewable because when they are destroyed, they cannot be replaced. As such, paleontological resources are afforded protection under various federal, state, and local laws. This Project is not subject to federal laws.

Consequently, all resources are protected under state and local laws, as described in the following sections.

2.1 STATE
California is among the states that protect significant paleontological resources. CEQA is the legal framework through which this protection is accomplished. Enacted in 1970, CEQA does not directly regulate land uses but instead requires state and local agencies within California to follow a protocol of analysis and public disclosure of unavoidable environmental impacts of proposed projects and to adopt all feasible measures to mitigate those impacts.

2.1.1 California Environmental Quality Act
This Project is subject to Section 15002(a)(3) of the Guidelines for Implementation of CEQA (California Code of Regulations, Title 14, Chapter 3), which states one of the basic purposes of CEQA is the intention to “prevent significant, avoidable damage to the environment by requiring changes in projects through the use of alternatives or mitigation measures when the governmental agency finds the changes to be feasible.” Therefore, CEQA requires detailed studies that analyze the environmental effects of a proposed project.

If a project is determined to have a potential significant environmental effect, the act requires that alternative plans and mitigation measures be considered. Specifically, Section VII(f) of Appendix G of the CEQA Guidelines, the Environmental Checklist Form, poses the question, “Will the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?” If paleontological resources are identified as being within the proposed project area, the sponsoring agency must take those resources into consideration when evaluating project effects. The level of consideration may vary with the importance of the resource.

2.1.2 CEQA Implementation
Guidelines for implementation of CEQA are codified in 14 CCR 15000 et seq., which requires state and local public agencies to identify the environmental impacts of proposed discretionary activities or projects, determine if the impacts will be significant, and identify alternatives and mitigation measures that will substantially reduce or eliminate significant impacts to the environment. The various agencies within state government all have their own guidance documents to assist with CEQA compliance. The City is the government agency responsible for CEQA compliance for the Project.

Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 6

2.2 LOCAL
In addition to state-level implementing regulations, policies, and guidance, various counties and municipalities throughout California also have developed environmental goals, policies, and guidance that pertain to paleontological resources. The following sections list all relevant goals, objectives, and policies.

2.2.1 County of Riverside
There are several policies covering paleontological resources within the County of Riverside (County) General Plan, Multipurpose Open Space (OS) Element (Riverside County Planning Department, 2015:OS-51):

OS 19.6: Whenever existing information indicates that a site proposed for development has high paleontological sensitivity as shown on Figure OS-8, paleontological resource impact mitigation program (PRIMP) shall be filed with the Riverside County Geologist prior to site grading. The PRIMP shall specify the steps to be taken to mitigate impacts to paleontological resources.

OS 19.7: Whenever existing information indicates that a site proposed for development has low paleontological sensitivity as shown on Figure OS-8, no direct mitigation is required unless a fossil is encountered during site development. Should a fossil be encountered, the Riverside County Geologist shall be notified and a paleontologist shall be retained by the project proponent. The paleontologist shall document the extent and potential significance of the paleontological resources on the site and establish appropriate mitigation measures for further site development.

OS 19.8: Whenever existing information indicates that a site proposed for development has undetermined paleontological sensitivity as shown on Figure OS-8, a report shall be filed with the Riverside County Geologist documenting the extent and potential significance of the paleontological resources on site and identifying mitigation measures for the fossil and for impacts to significant paleontological resources prior to approval of that department.

OS 19.9: Whenever paleontological resources are found, the County Geologist shall direct them to a facility within Riverside County for their curation, including the Western Science Center in the City of Hemet.

2.2.2 City of San Jacinto
The City’s General Plan, Resource Management (RM) Element also includes goals, policies, and implementation program that pertain to paleontological resources (City of San Jacinto, 2006:RM-9 and Appendix RM-5 and RM-6). Those within the cultural resources section of the document that are relevant to paleontological resources include:

Resource Management (RM) Goal 4: Promote cultural awareness through the preservation of the City’s historical, archaeological, and paleontological resources.

The first two policies, a and b, cover archaeological and builtenvironment resources, but the third policy addresses paleontological resources:
c. The City shall require an assessment of the potential for development proposals to significantly impact paleontological resources pursuant to the California Environmental Quality Act Guidelines. If the project involves earthworks, the City may require a study conducted by a professional paleontologist to determine if paleontological assets are present, and if the project will significantly impact the resources. If significant impacts are identified, the City may require the project to be modified to avoid impacting the paleontological materials, require monitoring of rock units with high potential to contain significant nonrenewable paleontologic [sic] resources, or require mitigation measures to mitigate the impacts, such as recovering the paleontological resources for preservation.

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 8 3 PALEONTOLOGICAL RESOURCE ASSESSMENT GUIDELINES
Protection of paleontological resources requires assessment of the potential for geologic units to yield significant paleontological resources that could be directly or indirectly impacted or destroyed during Project development. Successful protection also involves the formulation and implementation of appropriate management measures to mitigate impacts. Mitigation measures are proportional to the potential of individual areas to yield intact and significant paleontological resources.

3.1 DEFINITION OF PALEONTOLOGICAL RESOURCES AND

SIGNIFICANCE CRITERIA
The SVP guidelines define paleontological resources as fossils and fossiliferous deposits (SVP, 2010). Fossils are the evidence of once-living organisms as preserved in the rock record. They include both the lithified remains of ancient plants and animals and the traces thereof (trackways, imprints, burrows, etc.). In general, the SVP considers fossils to be greater than 5,000 years old (older than middle Holocene1
) and to typically be preserved in sedimentary rocks, although certain volcanic rocks and low-grade metamorphic rocks may be fossiliferous if formed under certain conditions.

Well-preserved and identifiable individual fossils are considered significant paleontological resources if they are a type specimen, rare, a complete specimen, or part of an important diverse fossil assemblage. Of particular importance are fossils found in situ, or in their primary geologic context. These fossils are important because they are used to examine evolutionary relationships, provide insight on the development of and interaction between biological communities, establish time scales for geologic studies, and for many other scientific purposes, including investigation into paleoenvironments and paleoclimates (Scott and Springer, 2003; SVP, 2010). Among the various types of fossils, intact and in situ vertebrate fossils are usually assigned a greater significance than other types as they are comparatively rare. Consequently, more attention tends to be placed on the recovery of vertebrate fossils than other types.

3.2 PROFESSIONAL STANDARDS AND CLASSIFICATION OF

PALEONTOLOGICAL RESOURCE SENSITIVITY
Most professional paleontologists in California adhere to the guidelines set forth by the SVP (2010) and industrywide standards (Murphey et al., 2019) to determine the course of paleontological mitigation for a given project unless specific city, county, state, or federal guidelines are available. The City does not have its own paleontological sensitivity guidelines.

However, the County of Riverside (County) has developed a system that establishes detailed protocols for the assessment of the paleontological sensitivity of a project area and outlines 1 Middle Holocene: the Holocene Epoch is subdivided into early (11,700 to 8,200 years ago), middle (8,200 to 4,200 years ago), and late (4,200 years ago to present) subepochs (Cohen et al., 2023). The Quaternary Period also includes the older Pleistocene Epoch, which is also subdivided into early (2.6 million to 1.8 million years ago), middle (1.8 million to 77,400 years ago), and late (77,400 to 11,700 years ago) subepochs (Cohen et al., 2023).

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 9 measures to follow in order to mitigate adverse impacts to known or unknown fossil resources during project development (County of Riverside, 2015). Therefore, this PRA utilizes the County’s ranking system and mitigation measures.

Following the County’s established process, baseline information is used to assign the paleontological sensitivity of a geologic unit(s) (or members thereof) to one of four categories— Low, Undetermined, High A (Ha), and High B (Hb) (County of Riverside, 2015). Table 3-1 shows the criteria for the categories in comparison with those of the SVP as well as mitigation recommendations for each category.

Table 3-1
Paleontological Sensitivity Classifications
Sensitivity/Potential
County of
Riverside SVP Criteriaa Mitigation Recommendationsb
High A
High B
High Rock units from which vertebrate or
significant specimens of other fossil
types have been recovered are
considered to have a high potential.

Rock units with high potential also
may include rock units that are
temporally or lithologically suitable for
the preservation of fossils (e.g., Middle
Holocene and older, argillaceous and
carbonate-rich paleosols, fine-grained
marine sandstones, etc.). Rock units
with High B Sensitivity are considered
to have high potential at depths greater
than 4 feet bgs.

Retain a qualified paleontologist and
typically complete a field survey,
PRIMP, and on-site construction
monitoring. Any significant
specimens discovered during
monitoring will need to be prepared,
identified, and curated into a
museum. A final report documenting
the significance of the finds will also
be required.

Undetermined Undetermined In some cases, available literature on a particular rock unit will be scarce and a
determination of whether or not it is
fossiliferous or potentially fossiliferous
will be difficult to make. Under these
circumstances, further study is needed
to determine the unit’s paleontological
resource potential.

A field survey is required to further
assess the unit’s paleontological
potential. The survey may provide
data for development of a PRIMP
prior to construction.

Low Low Rocks units from which few fossils have
been recovered or generally unsuitable
for preservation of fossils are
considered to have a low potential.

These units typically yield fossils only
on rare occasions and under unusual
circumstances (e.g., basalt flows,
recent colluvium, etc.).

Mitigation is not typically required;
however, if an unanticipated
paleontological resource is
encountered, a qualified professional
paleontologist (Principal
Investigator, Project Paleontologist)
may need to evaluate the resource to
consider mitigation.

N/A No Potential Rock units that have no potential for
paleontological resources are those that
are formed under or exposed to
immense heat and pressure, such as
high-grade metamorphic rocks and
plutonic igneous rocks.

No mitigation required.

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 10 4 METHODS
This PRA was completed through desktop studies and a field survey. The twofold purpose of the off- and on-site research was: (1) to identify the geologic units in the Project area and immediate vicinity to determine whether previously recorded paleontological localities occur either within the Project area or within the same geologic units nearby and (2) to determine the sensitivity of the geologic units in the Project area for their potential to yield paleontological resources.

4.1 LITERATURE REVIEWS AND MUSEUM RECORDS SEARCHES
In many areas, the near-surface layers of sediments and sedimentary rocks are broken down and converted to soil (pedogenesis) through chemical and physical weathering processes (Boggs, 2012). During pedogenesis, any fossils preserved within the near-surface layers often are destroyed or rendered unrecognizable. Therefore, intact and identifiable fossils are unlikely to be found in soil. Reviews of relevant geologic maps, regional geological publications, and unpublished reports are necessary to ascertain the geology and stratigraphy of a project area to determine the potential for significant subsurface paleontological resources.

To supplement the map and literature reviews, Æ requested searches of records of the invertebrate and vertebrate collections maintained by the Natural History Museum of Los Angeles County (NHMLAC) and the Western Science Center of Hemet (WSC). Æ also completed online searches of two databases readily available to the public—the Paleobiology Database (PBDB) and the database maintained by the University of California Museum of Paleontology (UCMP). All records searches were completed to identify known fossil localities within or near the Project area. In addition to the museum records searches, Æ examined the geotechnical investigation report for the Project (Marquez, 2023).

4.2 FIELD SURVEY
Prior to the field survey, Shi examined recent aerial photographs of the entire Project area in Google Earth to determine likely locations of geologic outcrops and potential survey routes. For the purpose of discussing survey locations, we have defined two subareas within the Project area.

The northwestern subarea includes the northwestern terminus where the proposed channel alignment meets the existing Metropolitan Water District of Southern California aqueduct rightof-way. An array of greenhouses is located in the central portion of this subarea. The southeastern subarea includes the large joint flood-control and confluence basin at the southeastern terminus, which borders the San Jacinto Reservoir. A homestead also is in the central portion of this subarea. The east-west and north-south stretches of the alignment between these two subareas cross several agricultural fields.

Victor Jiménez-González conducted the paleontological field survey for the Project on November 29, 2023, alongside Æ Associate Archaeologist Andrew DeLeon, who conducted the cultural field survey. The purpose of the survey was to confirm the presence or absence of exposed fossils on the ground surface and to evaluate geologic exposures for their potential to yield significant subsurface paleontological resources.

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 11 Jiménez-González started the survey from the northwestern subarea and proceeded east parallel to Ramona Expressway, then south parallel to Sanderson Avenue before crossing the street and proceeding south to the southeastern subarea. He completed the survey with a combination of close visual inspection and spot-checking. Close visual inspection was conducted where the ground surface was visible and sediments were exposed, including (1) near the array of greenhouses in the northwestern subarea; (2) around the perimeter of the homestead; and (3) within agricultural fields along the north-south stretch of the alignment north of the homestead.

Jiménez-González spot-checked the remainder of the Project area where the ground surface was obscured by vegetation, including (1) most of the northwestern subarea north of the greenhouses; (2) the east-west stretch of the alignment parallel to Ramona Expressway; and (3) most of the southeastern subarea south of the homestead. He used a cellular Global Positioning System receiver to navigate through the Project area, provided notes on his field form using the ArcGIS Survey123 application, and took photographs to document the survey. Any fossils encountered were to be field-documented and not collected.

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 12 5 GEOLOGY AND PALEONTOLOGY
The following sections provide the geological context of the Project area, descriptions of the geologic units mapped as surface exposures within the boundaries of the Project area, and units exposed nearby and thought to be present in the subsurface. The section also includes any paleontological information reported from the units.

5.1 REGIONAL GEOLOGY
The Project area is in the San Jacinto Valley within the northern part of the geologically complex Peninsular Ranges geomorphic province (California Geological Survey, 2002)2. Derived from the same massive batholith (i.e., very deep igneous intrusion) as the core of the Sierra Nevada, the Peninsular Ranges are a series of mountain ranges separated by northwest-trending valleys formed from faults branching from the San Andreas Fault (Norris and Webb, 1976; California Geological Survey, 2002). The mountain ranges are bounded to the east by the Colorado Desert and range in width from 30 to 100 miles (Norris and Webb, 1976).

The Project area is within the San Jacinto Fault Zone and is crossed by the northwest-southeasttrending Casa Loma Fault (Morton et al., 2006a, 2006b). The geologic units in the region date from the Paleozoic3 to the present, with basement rocks represented by the Mesozoic4 Peninsular Ranges batholith and prebatholithic metasedimentary and metavolcanic rocks (Jahns, 1954; Morton et al., 2006b). Thick sequences of Cenozoic5 sediments, mostly Quaternary in age, have accumulated above these in the valleys of the region.

5.2 GEOLOGY AND PALEONTOLOGY OF THE PROJECT AREA
The Project area is mapped on the Lakeview and San Jacinto quadrangles at a scale of 1:24,000 by Morton and Matti (2001) and Dibblee and Minch (2003), respectively. However, more recent 2 A geomorphic province is a region of unique topography and geology that is readily distinguished from other regions based on its landforms and tectonic history (American Geological Institute, 1976). 3 Paleozoic Era: Approximately 539 to 252 million years ago, subdivided into six periods—Cambrian (539–485 million years ago), Ordovician (485–444 million years ago), Silurian (444–419 million years ago), Devonian (419– 359 million years ago), Carboniferous (359–299 million years ago), and Permian (299–252 million years ago) (Cohen et al., 2023). 4 Mesozoic Era: Approximately 252 to 66 million years ago, subdivided into three periods—Triassic (252– 201 million years ago), Jurassic (201–145 million years ago), and Cretaceous (145–66 million years ago) (Cohen et al., 2023). 5 Cenozoic Era (formerly Tertiary): 66 million years ago to present, subdivided into three periods—Paleogene (66– 23 million years ago), Neogene (23–2.6 million years ago), and Quaternary (2.6 million years ago to present). The Paleogene Period is subdivided into the Paleocene, Eocene, and Oligocene epochs; the Paleocene Epoch lasted from approximately 66 to 56 million years ago, the Eocene Epoch lasted from approximately 56 to 34 million years ago, and the Oligocene Epoch lasted from approximately 34 to 23 million years ago. The Neogene Period is subdivided into the Miocene and Pliocene epochs; the Miocene Epoch lasted from approximately 23 to 5.3 million years ago and the Pliocene Epoch lasted from approximately 5.3 to 2.6 million years ago. The Quaternary Period is subdivided into the Pleistocene and Holocene epochs; the Pleistocene Epoch, or last Ice Age, lasted from approximately

2.6 million to 11,700 years ago when the Holocene Epoch began; all dates according to Cohen et al. (2023).

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 13 geologic map compilations at a scale of 1:100,000 by Morton et al. (2006a) and Lancaster et al. (2012) have refined the geology of the these quadrangles and therefore, the geologic map of the Project area (Figure 5-1) is based on these compilations. The following subsections provide additional information from Morton et al. (2006b) where relevant. The subsections also summarize the findings from 19 borings completed along the entire channel alignment as part of the geotechnical investigation (Marquez, 2023).

5.2.1 Young Alluvial-Valley Deposits (Qyva/Qya and Qyv1a) The majority of the Project area falls within undifferentiated late Pleistocene to Holocene young alluvial-valley deposits (Qyva), according to the surface geology map by Morton et al. (2006a).

In addition, small wedges of the oldest, late Pleistocene to early Holocene subunit of the deposits (Qyv1a) occur at the ground surface of the southwestern corner of the northwestern subarea and the west-southwestern side of the southeastern subarea (Morton et al., 2006a). The geologic contact between Qyv1 and Qyva is delineated by the Casa Loma Fault (Morton et al., 2006a). The surface geology of the easternmost third of the southeastern subarea is also mapped by Lancaster et al. (2012) as late Pleistocene to Holocene young alluvial-valley deposits but is instead labeled as Qya. Qyva and Qya sediments are fluvial deposits commonly present along valley floors in the region and consist of unconsolidated to slightly consolidated, undissected to slightly dissected sand, silt, and clay (Morton et al., 2006a, 2006b; Lancaster et al., 2012). These deposits are mostly sandy in composition (subscript “a” = arenaceous) in the vicinity of the Project area. The composition of Qyv1a (Morton et al., 2006a, 2006b) does not differ markedly from that of the Qyva and Qya deposits, other than gravel reported by Lancaster et al. (2012) for the latter unit.

The boring logs from the geotechnical report show alluvial deposits from a depth of 0.5–2.5 feet bgs to their maximum depths of either 21.5 or 51.5 feet bgs (Marquez, 2023). In most of the borings, the deposits alternate between beds with varying proportions of sand and silt (i.e., sand, silty sand, sand with silt, sandy silt, silt with sand). Three of the borings (B-1, B-4, and B-15) also encountered beds of clayey sand. The authors of the report used Morton and Matti (2001) as their reference, and their observations are consistent with the mapping. Specifically, the geologic units mapped in the Project area in Morton and Matti (2001)are identical to those mapped in Morton et al. (2006a), as the latter incorporates data from the former.

All beds of the young alluvial-valley deposits older than middle Holocene in age are potentially fossiliferous. In particular, Pleistocene alluvial deposits are well documented to have yielded a wide variety of megafauna as well as numerous invertebrate and plant taxa throughout inland valleys of Riverside and San Bernardino counties (Reynolds and Reynolds, 1991; Scott, 2007; Springer et al., 2009).

5.2.2 Artificial Fill
Marquez (2023) reported the presence of artificial fill in all the borings to depths of 0.5–2.5 feet bgs. The fill consists of locally derived sandy silt and silty sand. Because the fill consists of local, potentially fossiliferous sediments, it may yield fossils. However, such fossils, if present, are unlikely to be significant as they would be removed from their primary geologic context and may have become damaged during excavation and transport. Despite this, the fill forms only a thin veneer over undisturbed alluvial deposits in the Project area. Therefore, significant, in situ fossils may be preserved in the shallow subsurface just beneath the fill.

Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 15 6 RESULTS AND ANALYSIS
This chapter reports on the results of the desktop studies and fieldwork completed for this Project. Paleontological sensitivity rankings also are assigned to the geologic units mapped at the ground surface as well as those likely present at unknown depths based on the available information.

6.1 GEOTECHNICAL REPORT
The geotechnical investigation for the Project included excavation of 19 hollow-stem auger borings to depths of either 21.5 or 51.5 feet bgs along the length of the Project area, with B-1 completed in the northwestern subarea and B-19 completed in the southeastern subarea (Marquez, 2023). Specifically, borings B-1, B-2, and B-4 reached a depth of 51.5 feet bgs, whereas the rest terminated at 21.5 feet bgs. From the boring logs, a layer of artificial fill derived from local sandy silt and silty sand is at 0.5–2.5 feet bgs, followed by alternating beds of alluvial sand and silt of varying proportions, which extend to the maximum depths of the borings. Three of the borings (B-1, B-4, and B-15) also show beds of clayey sand at various depths. As discussed in the previous chapter, the authors noted the alluvial sediments were consistent with mapping by Morton and Matti (2001), whose geologic data was incorporated into Morton et al. (2006a). No paleontological resources were encountered during the geotechnical investigation.

6.2 RECORDS SEARCHES
The UCMP online database does not list any localities within a 10-mile radius of the Project area. Records search results from the PBDB, WSC, and NHMLAC are detailed below in Table 6-1, which shows all listings within a 10-mile radius of the Project area. The PBDB online database does not list any fossil localities from Pleistocene alluvial deposits within the Project area but shows numerous localities reported from Lakeview 5–6 miles to the west. The WSC search did not yield any localities within the Project area, although numerous localities are listed from Pleistocene alluvial deposits reported during construction of the Eastside Pipeline Project

1.5–2 miles to the southwest. The NHMLAC records search results do not report any localities within the Project area, although several nearby localities to the south-southwest are listed from geologic units similar to those mapped in or in the vicinity of the Project area.

6.3 FIELD SURVEY RESULTS
Low ground visibility and the absence of geologic outcrops or road cuts (Figure 6-1) limited Æ’s close field examinations of the surficial geology in the Project area. The ground surface throughout the Project area was mostly obscured by vegetation, particularly in much of the northwestern and southeastern subareas and in the east-west stretch of the alignment parallel to Ramona Expressway. Jiménez-González observed exposed sediments in a few locations including the perimeter of the greenhouses in the northwestern subarea (Figure 6-2), the perimeter of the homestead in the southeastern subarea (Figure 6-3), and on dirt roads and fields between patches of vegetation along the linear, north-south stretch of the alignment in the southern half of the Project area (Figure 6-4). Most of these exposed sediments appear to have been previously disturbed from cultivation or landscaping. Jiménez-González also observed spoil DRAFT

Because of the low ground visibility, lack of geologic outcrops or road cuts, and previous disturbances throughout most of the Project area, little geologic information such as stratigraphy was discernible during the survey. Of the sediments Jiménez-González did observe, he recorded poorly sorted, white (10YR 8/1) to gray (10YR 6/1) silty sand with angular gravel throughout the entire Project area. He did not observe any notable changes in lithology and did not encounter any paleontological resources during the survey.

6.4 DETERMINATION OF PALEONTOLOGICAL RESOURCE POTENTIAL

WITHIN THE PROJECT AREA
Using information obtained from the desktop studies and field survey, Æ determined the paleontological resource potential of the Project area. Æ’s paleontological sensitivity rankings follow the County of Riverside (2015) classification system. Based on the findings, Æ recommends the assignment of High B Sensitivity to the entire Project area (Figure 6-5).

Æ did not observe any exposures of unequivocally undisturbed alluvial deposits during the survey. Based on the presence of artificial fill in all of the boring logs and the extent of previous disturbance in the Project area, most of the sediments Æ observed during the survey may have been the locally derived artificial fill described by (Marquez, 2023). Therefore, we consider the surficial sediments in the Project area unlikely to yield significant paleontological resources.

However, Æ’s desktop studies indicate deposits of Qyva/Qya as well as Qyv1a have a high potential of preserving significant paleontological resources particularly with increasing depth. (Marquez, 2023) described sediments matching the descriptions of Qyva/Qya at a depth of 0.5–

2.5 feet bgs, just below artificial fill, throughout the Project area. Therefore, construction monitoring for paleontological resources from 4 feet bgs and downward (i.e., High B recommendation) may result in observations that can help to further refine our understanding of the geology of the Project area.

DRAFT
Paleontological Resource Assessment for the San Jacinto Master Drainage Plan Line E 21 7 RECOMMENDATIONS
Æ concludes that construction activities may impact significant paleontological resources in various locations throughout the Project area. Æ’s desktop studies indicate the Project area has High B Sensitivity for paleontological resources.

Prior to the issuance of grading permits and consistent with applicable policies (County of Riverside, 2015), Æ recommends a PRIMP be prepared by a qualified professional paleontologist (Paleontological Principal Investigator, Project Paleontologist) as defined by mitigation paleontology industry standards (Murphey et al., 2019) and/or the SVP (2010). The PRIMP will specify the steps to be taken to mitigate impacts to paleontological resources. For instance, Worker’s Environmental Awareness Program training should be prepared prior to the start of Project-related ground disturbance and presented in person to all field personnel to describe the types of paleontological resources that may be found and the procedures to follow if any are encountered.

The Project-specific PRIMP also will include a monitoring plan that will indicate where construction monitoring should occur and the frequency of required monitoring (i.e., full-time, spot-checks, etc.). In addition to construction monitoring procedures, the monitoring plan also will provide details about fossil collection, analysis, and preparation for permanent curation at an approved repository, such as the WSC. Lastly, the monitoring plan will describe the different reporting standards to be used, such as monitoring with negative findings versus monitoring resulting in fossil discoveries.

2217.0031L100/R Phase I Environmental Site Assessment | ROUX | iii Executive Summary
Shea Properties (User) retained Roux Associates, Inc. (Roux) to perform a Phase I Environmental Site Assessment (ESA) of the property located along North Sanderson Avenue and Record Road in San Jacinto, Riverside County, California; the property is identified as the Line E - Orange Proposed Irrigation Channel Alignment (Subject Property; Figure 1). Roux performed this Phase I ESA in general accordance with the American Society for Testing Materials (ASTM) Standard Practice for Environmental Site Assessments:

Phase I Environmental Site Assessment Process (ASTM E1527-21) in an effort to identify, to the extent feasible, the presence of recognized environmental conditions (RECs) with respect to the Subject Property as defined in ASTM E1527-21. Exceptions to, or deletions from, this practice are described in Section 9.1 of this report.

The Subject Property consists of a proposed irrigation channel alignment, referred to as the Line E - Orange Proposed Irrigation Channel Alignment, that traverses nine individual parcels (collectively identified as the Parent Property) with Riverside County Assessor’s Parcel Numbers (APNs) 436-170-008, 436-170-016, 436- 170-001, 436-030-004, 436-010-003, 432-030-012, 432-030-010, 432-030-006, and 430-100-018 (Parcels 1 through 9; Figure 2). The proposed irrigation channel project will include buffer and support areas (Figure 2) for construction activities (such as equipment staging), which are largely located within the Parent Property but are not included as part of the Subject Property. North Sanderson Avenue, a north-south trending road, transects the Parent Property and is located east of Parcels 6 and 7 and west of Parcels 2 through 5. Record Road, an east-west trending road, also transects the Parent Property and is located north of Parcels 6 through 8 and south of Parcel 9. A description of the use and/or operation of the Parent Property and each Subject Property area is provided below:
• Parcel 1 is developed with the western portion of the San Jacinto Reservoir. The Subject Property portion of Parcel 1 consists of berms and unpaved roadways. • Parcel 2 is developed as a ranch for retired horses operated by the California Equine Retirement Foundation (805 North Sanderson Avenue). The Subject Property portion of Parcel 2 consists of a vacant area with no structures or notable features;
• Parcel 3, including the Subject Property portion, consists of vacant land; • Parcel 4, including the Subject Property portion, consists of an agricultural field (watermelon); • Parcel 5, including the Subject Property portion, consists of an agricultural field (unknown leafy crop); • Parcel 6, including the Subject Property portion, consists of an agricultural field (watermelon); • Parcels 7 and 8, including the Subject Property portions, consist of vacant land; and • Parcel 9, including the Subject Property portions, consists of an enclosed agricultural field (unknown crop) with greenhouse farming structures.

Based on a review of historical sources, the following site histories were identified for the Parent Property, including Subject Property areas:
• Parcel 1 was vacant land as early as 1901 and has been developed as part of the San Jacinto Reservoir since at least 1949. The Subject Property area of Parcel 1 has consisted of berms and unpaved roadways since the parcel was developed as part of the Reservoir. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | iv • Parcels 2, 3, and 4 were vacant land as early as 1901. By 1949, a dwelling and multiple structures (likely associated with agricultural operations of the surrounding area) were apparent on the westernmost portions of Parcels 2, 3, and 4. Duck ponds were depicted within the central portions of Parcel 3 and 4 (outside the Subject Property area) between the 1960s through 2015 when the land was developed with row crops as part of agricultural operations. The current horse retirement facility and associated structures and features were present on Parcel 2 by 2006. No structures have been present in the Subject Property area of Parcel 2.
• Parcel 5 was vacant land as early as 1901 through the 1940s when the parcel was used as agricultural land. A duck pond (part of a series of duck ponds) was depicted on the eastern portion of the parcel (and within the Subject Property area) from the 1960s through 2012 when the parcel was converted to agricultural land.
• Parcels 6, 7, and 8, including the Subject Property areas, were vacant land from as early as 1901.

By the 1950s, Parcels 6, 7, and 8 were agricultural land with various unpaved roads. A small structure, likely associated with the agricultural operations in the area, was located on the Subject Property portion of Parcel 8 from at least 1975 through 2002. Parcel 8 has been vacant or agricultural land since 2005.
• Parcel 9, including the Subject Property area, was vacant land from as early as 1901 through the 1970s when two small structures, likely associated with the surrounding agricultural operations, appeared within the southwestern portion of the parcel. Parcel 9, including the Subject Property area, was most recently developed with greenhouse farming structures starting in 2023.

On October 12 and 13, 2023, Roux visually assessed the Subject Property during the site reconnaissance for potential RECs, including, but not limited to, potential underground storage tanks (USTs), aboveground storage tanks (ASTs), polychlorinated biphenyl (PCB)-containing equipment, hazardous materials storage or handling areas, containerized or bulk wastes, and visual indications of impacted soil.

Roux, on behalf of User, conducted previous Phase I ESAs and subsurface investigations of Parcels 7 and 8 in 2021 and Parcel 6 in 2023. The Phase I ESAs and subsurface investigations were prepared under separate covers; previous environmental issues identified as RECs, hRECs, and/or OEFs with respect to Parcels 6, 7, and 8 were addressed in the subsurface investigations. Based on the analytical results of the 2021 and 2023 investigations, Roux did not recommend any further investigations with respect to Parcels 6, 7, and 8 (including the Subject Property areas).

Roux also performed a records review in an effort to identify RECs in connection with the Subject Property.

This records review addressed the Subject Property and surrounding properties. Roux reviewed commercially available records associated with the Subject Property and nearby properties to assess potential concerns associated with the migration of hazardous substances. The records review also included reasonably ascertainable historical data, which can be helpful in identifying the past uses of the Subject Property and surrounding areas, as it may relate to the environmental condition of the Subject Property.

Roux performed interviews and/or file reviews with various government agencies and other parties with possible knowledge of the Subject Property and surrounding properties in an effort to identify current and past uses of the Subject Property and surrounding areas, as they may relate to the environmental condition of the Subject Property.

ASTM E 1527-21 defines a Recognized Environmental Condition (REC) as:
“The presence of hazardous substances or petroleum products in, on, or at the Subject Property due to a release to the environment; (2) the likely presence of hazardous substances or petroleum 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | v products in, on or at the Subject Property due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on or at the Subject Property under conditions that pose a material threat of a future release to the environment. A de minimis condition is not a recognized environmental condition.”
A Controlled Recognized Environmental Condition (cREC) as:
“A recognized environmental condition affecting the Subject Property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations and other property use limitations.” And a Historical Recognized Environmental Condition (hREC) as:
“A previous release of hazardous substances or petroleum products affecting the Subject Property that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the Subject Property to any controls (for example, activity and use limitations and other property use limitations.”
The term recognized environmental condition is not intended to include de minimis conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.

This Executive Summary provides a brief overview of the findings of this Phase I ESA. Although the Executive Summary is an integral part of a report, it does not substitute for reading the entire report or the appended or referenced documents in order to fully understand the findings and potential environmental concerns associated with the Subject Property.

Recognized Environmental Conditions (RECs)
Based on the information obtained through the performance of this Phase I ESA, Roux identified the following RECs in connection with the current and historical operations at the Subject Property or adjoining properties.

To the extent possible, the locations of the RECs are shown in Figure 2. To avoid confusion, all RECs, cRECs, hRECs, and OEFs are numbered sequentially.

REC 1 – Former Agricultural Applied Pesticide Area. According to aerial photographs, agricultural operations (row crops) have been conducted on Parcels 3, 4, 5, 6, 7, and 8 (including Subject Property areas) since at least 1949. Parcel 9 appeared developed for agricultural use circa 1975 and again in 2023. Based on the long-term agricultural use, it is possible that agricultural chemicals, such as organochlorine, lead-based, and arsenic-based pesticides, herbicides, and fertilizers, may have been used on-site within Parcels 3 through 8. Previous site investigations conducted within Parcels 6, 7, and 8 did not identify significant evidence of soil contamination associated with historical crop growth. The potential for impacts from agricultural chemicals to onsite soils within Parcels 3, 4, 5, and 9 is considered a REC.

Controlled Recognized Environmental Conditions (cRECs)
Roux did not identify known or suspected cRECs in connection with the current and historical operations at the Subject Property or adjoining properties.
2217.0031L100/R Phase I Environmental Site Assessment | ROUX | vi Historical Recognized Environmental Conditions (hRECs)
Roux did not identify known or suspected hRECs in connection with the current and historical operations at the Subject Property or adjoining properties.

Other Environmental Features (OEFs)
The term recognized environmental condition is not intended to include de minimis conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Other environmental features (OEFs) are environmental conditions that do not meet the definition of a REC, but which may warrant mention in a comprehensive Phase I ESA. Based on the subject Phase I ESA, Roux identified the following OEFs.

OEF 2 – Adjoining Dairy Ponds. The west adjoining dairy farm features several ponds, likely used to store dairy farm effluent including manure. At the time of the inspection, no water was observed in the ponds. The likely use of the adjoining dairy ponds for disposal of dairy farm effluent (including manure) is considered an OEF due to the potential generation and migration of methane gas. The Subject Property is slated to be redeveloped with an irrigation channel with no structures, minimizing the concern for gases beneath future inhabited buildings or structures. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 1

1. Introduction
Roux Associates, Inc. (Roux) completed this Phase I Environmental Site Assessment (ESA) of the property located along North Sanderson Avenue and Record Road in San Jacinto, Riverside County, California; the property is identified as the Line E - Orange Proposed Irrigation Channel Alignment (Subject Property). The Subject Property consists of a proposed irrigation channel alignment and traverses nine individual parcels (collectively identified as the Parent Property) with Riverside County Assessor’s Parcel Numbers (APNs) 436-170-008, 436-170-016, 436-170-001, 436-030-004, 436-010-003, 432-030-012, 432-030-010, 432-030- 006, and 430-100-018 (Parcels 1 through 9). The Subject Property location is shown in Figure 1 and the Subject Property and vicinity is shown in Figure 2. Roux performed this Phase I ESA in compliance with the scope and limitations of American Society for Testing Materials (ASTM) E1527-21 and the terms and conditions of Roux’ proposal dated July 28, 2023. Roux conducted this Phase I ESA for the benefit of Shea Properties (the User).

The following sections of this report present our Phase I ESA findings and conclusions. A glossary containing terms and definitions presented in ASTM E1527-21 is included in Appendix A – Glossary of Terms. Other appendices presented at the end of the report include historical topographic maps, historical aerial photographs, regulatory records review documentation, applicable historical records, and personnel qualifications.

1.1 Purpose
The purpose of this Phase I ESA is to identify and report, to the extent feasible, recognized environmental conditions (RECs) with respect to the Subject Property. Performing a Phase I ESA in general compliance with ASTM E 1527-21 may enable a User to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) liability. That is, the practice that constitutes one of the requirements for “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined in 42 USC Section 9601(35) (B).

1.2 Scope of Services
The scope of services for this Phase I ESA included, but was not limited to, the activities listed below. • A review of reasonably ascertainable and practicably reviewable topographic maps, historical aerial photographs, and city directories, if available, to investigate current and past uses of the Subject Property and surrounding properties;
• A review of specific government lists pursuant to ASTM Standard E 1527-21 regarding environmental activities for the Subject Property and local area properties; • A review of recorded land title records, building, assessors, and fire department records, for permits, citations, and reports connected to the Subject Property that were reasonably ascertainable, practicably reviewable, and publicly available within reasonable time and cost; • An inspection by an environmental professional to investigate the current use of the Subject Property and to identify environmental concerns including but not limited to, the presence of hazardous substances or petroleum products, wastes, underground storage tanks (USTs), aboveground storage tanks (ASTs), or other environmental concerns;
2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 2 • Interviews with available representatives of the owner of the Subject Property, occupants, and local government officials by an environmental professional; and • Preparation of this Phase I ESA report.

Roux initiated this Phase I ESA pursuant to receipt of written authorization to proceed on September 21, 2023.

1.3 Standard of Care
Roux conducted this Phase I ESA using a defined scope of services considered appropriate and agreed upon by all parties on the date the service was authorized, unless the scope of services or the methods used were later modified, in writing, and accepted by all parties prior to performance. Roux conducted this Phase I ESA in accordance with generally accepted practices in a manner consistent with that level of care exercised by other members of our profession in the same locality and under similar conditions of time and accessibility of improvements and information. No other representations, expressed or implied, and no warranty or guarantee is included or intended to be part of this Phase I ESA.

Please note that the scope of services performed in execution of this assessment may not be appropriate to satisfy the needs of other parties. We, therefore, are not responsible for independent conclusions, opinions, or recommendations of others based on our assessment. Furthermore, this Phase I ESA relates to the environmental conditions of the Subject Property and does not address issues raised in transactions such as business risk, purchase of business entities, or interests therein, or of their assets, that may well involve environmental liabilities pertaining to properties previously owned or operated or other off-site liabilities.

Additionally, the findings of this Phase I ESA are based on Roux’ observations, inquiries, and historical research using reasonably ascertainable and practically reviewable information obtained within reasonable time and cost constraints. Roux does not represent that this Phase I ESA is an exhaustive investigation that reflects the findings of all of the information available for the Subject Property, nor is it representative of future Subject Property conditions. If additional information is generated from the Subject Property, it should be provided to Roux so that we may evaluate its impact on our conclusions. As such, activities or episodes that transpire subsequent to this Phase I ESA are not considered in this assessment. It is not intended that a Phase I ESA in accordance with ASTM E1527-21 be an exhaustive assessment of a property nor can it wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property.

1.4 Assumptions
This Phase I ESA Report, including the exhibits attached hereto, describes the results of Roux’ investigation to identify the presence of recognized environmental conditions connected with the Subject Property in accordance with ASTM E1527-21, as allowed by and consistent with the regulatory requirements of the All Appropriate Inquiry Rule, 40 CFR Part 312, Amendment to Standards and Practices for All Appropriate Inquires Under CERCLA, Final Rule, published December 30, 2013 (AAI Rule). Specifically, the preamble to the amended AAI Rule states:

The Environmental Protection Agency (EPA) today is taking final action to amend the standards and practices for conducting all appropriate inquiries under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) to reference a standard practice recently made available by ASTM International, a widely recognized standards development organization. Specifically, this final 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 3 rule amends the ‘‘All Appropriate Inquiries Rule’’ at 40 CFR Part 312 to reference ASTM International’s E1527–13 ‘‘Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process’’ and make clear that persons conducting all appropriate inquiries may use the procedures included in this standard to comply with the All Appropriate Inquiries Rule1.

As of February 13, 2023, the EPA indicated that the updated standard ASTM E1527-21 is now AAI compliant.

While ASTM E1527-21 is now the current standard, the previous standard (ASTM E1527-13) is still AAI compliant until February 13, 2024.

One of the requirements that a person acquiring real property must meet in order to qualify for either the innocent landowner, contiguous owner, or bona fide prospective purchaser (collectively hereinafter “Prospective Purchaser”) defense to liability under the federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended by the Superfund Amendments and Reauthorization Act of 1986, and the Small Business Liability Relief and Brownfields’ Revitalization Act of 2002, 42 U.S.C. 9601-9675 (collectively referred to hereafter as “CERCLA”) is that person must conduct all appropriate inquiries into the previous ownership and uses of the property in conformance with the AAI Rule (or the ASTM E1527-21) prior to acquisition of the property. The User has acknowledged that, under the AAI Rule, Roux’ performance of this Phase I ESA in accordance with ASTM E1527-21 will not alone result in the User satisfying all requirements of the AAI Rule and will not in itself provide a defense to CERCLA liability. The User has acknowledged that the AAI Rule also requires that the Prospective Purchaser undertake certain additional inquiries and post-acquisition activities to satisfy the CERCLA AAI requirements. Accordingly, Roux makes no guarantees or warranties, expressed or implied, regarding this Phase I ESA, including without limitation, that this Phase I ESA will qualify the User for a defense to CERCLA liability.

Roux has performed this Phase I ESA in a professional manner using that degree of skill and care exercised for similar projects under similar conditions by reputable and competent environmental consultants.

Professional judgments expressed herein are based on the facts currently available to Roux.

The AAI Rule requires, and the conclusions and recommendations stated herein represent, the application of a variety of engineering and technical disciplines to material facts and conditions associated with the Subject Property. As such, these conclusions and recommendations are based on subjective interpretations and the exercise of discretion based on the facts available to Roux and conditions at the time of the performance of this Phase I ESA. Many of these facts and conditions are subject to change over time.

Accordingly, the conclusions and recommendations must be considered within this context.

The User has agreed that Roux shall not be responsible for conditions or consequences arising from relevant facts that were concealed, withheld, or not fully disclosed at the time this Phase I ESA was performed. To the extent practicable, Roux has identified data gaps, and has evaluated the potential significance of such data gaps. Recommendations to address those data gaps are presented herein and are based on the data available at the time of the performance of this Phase I ESA. Implementation of the recommendations may not fully address the data gaps, and the information obtained from execution of those recommendations may alter and/or modify the interpretation of the Subject Property conditions and conclusions, herein. This Phase I ESA does not include consideration of matters specifically excluded by ASTM E1527-21, including but not limited to, asbestos-containing building materials, radon, lead-based paint, lead in drinking water, wetlands, regulatory compliance, and mold unless specifically identified herein. 1 Federal Register: December 30, 2013 (Volume 78, Number 250) Page 79319 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 4 Emerging contaminants that are not defined as hazardous substances under CERCLA including, but not limited to per- and polyfluoroalkyl substances (PFAS) are outside the scope of the Phase I ESA. This Phase I ESA does not include the completion of searches for recorded environmental liens.

Roux has not collected any soil and/or groundwater samples on the Subject Property for Phase I purposes, and is relying on information presented by others, often in preliminary, draft, or verbal form. By referencing this information, Roux does not accept responsibility for the accuracy of the underlying data, sampling methods, laboratory analysis, or documentation.

This Phase I ESA Report should not be considered a legal interpretation of existing environmental laws and regulations. This Phase I ESA was conducted with a reasonable degree of inquiry to identify recognized environmental conditions, but uncertainty is not eliminated. No Phase I ESA can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property.

The Phase I ESA process is intended to reduce, but not eliminate, the uncertainty involved with identifying recognized environmental conditions.

This Phase I ESA Report is not an appraisal or value judgment of the Subject Property. The User has agreed that Roux shall not be liable for any use of this Phase I ESA Report as an appraisal or value judgment of the Subject Property.

This Phase I ESA Report has been prepared for the exclusive use of the User for specific application to the Subject Property covered by this Phase I ESA Report. The User has agreed that any third-party use of this Phase I ESA Report, upon disclosure by the User, is the sole responsibility and at the sole liability of the User.

1.5 User Reliance
No additional parties may use the information contained in this report without obtaining the written permission of Roux or the User. Roux’ duties and obligations extend to the User and to no other party. Roux’ duties and obligations to the User are not transferable to persons, corporations, or organizations without the express written consent of the User and Roux. The User may rely upon the information provided in this Phase I ESA report for a period of 180 days. After 180 days, this Phase I ESA should be updated in accordance with ASTM E1527-21 guidance. Roux will not be liable for any consequential damages arising from the use of this report for other than its intended purpose, for use of this report beyond 180 days of its issue date, or from unauthorized use by third parties.

This Phase I ESA report must be read and interpreted as a whole and can only be considered representative of the conditions of the Subject Property as of the date of our site reconnaissance described herein. Roux makes no representation whatsoever concerning the condition of the Subject Property beyond the date of our site reconnaissance described herein. Individual sections and appendices of this report are dependent on the balance of this report, and on the terms, conditions, and stipulations contained in the proposal and written amendments accepted by Roux.

West Hettinga Dairy, including ponds (1861 North Warren Road)

2.3 Past Use of the Subject Property
Based on a review of historical sources, the following site histories were identified for the Parent Property, including Subject Property areas:
• Parcel 1 was vacant land as early as 1901 and has been developed as part of the San Jacinto Reservoir since at least 1949. The Subject Property area of Parcel 1 has consisted of berms and unpaved roadways since the parcel was developed as part of the Reservoir. • Parcels 2, 3, and 4 were vacant land as early as 1901. By 1949, a dwelling and multiple structures (likely associated with agricultural operations of the surrounding area) were apparent on the westernmost portions of Parcels 2, 3, and 4. Duck ponds were depicted within the central portions of Parcel 3 and 4 (outside the Subject Property area) between the 1960s through 2015 when the land was developed with row crops as part of agricultural operations. The current ranch for retired horses and associated structures and features were present on Parcel 2 by 2006. No structures have been present in the Subject Property area of Parcel 2.
• Parcel 5 was vacant land as early as 1901 through the 1940s when the parcel was used as agricultural land. A duck pond (part of a series of duck ponds) was depicted on the eastern portion of the parcel (and within the Subject Property area) from the 1960s through 2012 when the parcel was converted to agricultural land.
• Parcels 6, 7, and 8, including the Subject Property areas, were vacant land from as early as 1901.

By the 1950s, Parcels 6, 7, and 8 were agricultural land with various unpaved roads. A small structure, likely associated with the agricultural operations in the area, was located on the Subject 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 7 Property portion of Parcel 8 from at least 1975 through 2002. Parcel 8 has been vacant or agricultural land since 2005.
• Parcel 9, including the Subject Property area, was vacant land from as early as 1901 through the 1970s when two small structures, likely associated with the surrounding agricultural operations, appeared within the southwestern portion of the parcel. Parcel 9, including the Subject Property area, was most recently developed with greenhouse farming structures starting in 2023.

3.1 Historical Sources
To help understand the history of the Subject Property and adjoining properties, historical sources were obtained from Environmental Data Resources, Inc. (EDR), of Shelton, Connecticut. The sources and locations within the Appendices are provided in the table below.

EDR Historical Sources
Historical Range Source Appendix
1901 – 2018 U.S. Geological Survey Topographic Maps B
1938 – 2020 EDR Aerial Photographs “Decade Package” C
No Available Coverage EDR “Certified Sanborn® Map Report” D 1976 – 2020 EDR “City Directory Image Report” E

3.2 Government Databases
To document potential sources of contamination at or near the Subject Property, a government records search was conducted by EDR. The search included local, state, and federal records for the Subject Property and for other properties within ASTM-standard distances of the Subject Property. The records search is summarized in Section 8.0 and copies of “The EDR Radius Map™ Reports with GeoCheck®” are included in its entirety as Appendix F. As recommended by ASTM, all but a few of the databases searched were “current,” i.e., had been updated within 90 days prior to the search date.

3.3 Site Reconnaissance
Roux personnel conducted a reconnaissance of the Subject Property, Parent Property, and surrounding areas on October 12 and 13, 2023. During the site reconnaissance, Roux representatives Ms. Ashley Whitaker and Ms. Francine Cason were able to access all areas of the Subject Property and representative areas of the Parent Property. The observations made during the site reconnaissance are discussed in Section 5.0 and throughout the report. A photographic log of the site reconnaissance is included as Appendix G.

3.4 Interviews
On October 12 and 13, 2023, Roux personnel contacted representatives of the Parent Property parcels via telephone and email regarding access to the Subject Property. No on-site items of features of significant environmental concern were noted during the site reconnaissance. No previous Subject Property owners/operators were available for an interview. This data gap is not considered significant due to sufficient 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 9 information regarding Subject Property history available from previous reports, EDR historical documents, and public records requests.

3.5 User Provided Information
ASTM E1527-21 provides an optional User Questionnaire to present select User-provided information that can assist in identifying possible RECs in connection with the Subject Property. According to ASTM E1527- 21, these tasks do not require the technical expertise of an environmental professional and the environmental professional generally does not perform these tasks. Roux administered the optional questionnaire to the User at the beginning of this Phase I ESA to assist them with these tasks; however, the completed questionnaire has not been returned to Roux as of this report date. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 10

Several portions of the Parent Property (and Subject Property) continue to be used for agricultural purposes (row crops). Environmental concerns associated with historical and current agricultural operations are discussed below in Section 5.2.

Aerial photographs and topographic maps indicate Parcels 3, 4, and 5 were developed with duck ponds between at least 1961 and 1989. Hunting and shooting range, such as those potentially associated with duck ponds, may impact shallow site soils with deposited lead from bullets and other metals. However, evidence indicating local hunting, shooting, or gun club activities was not identified at or near the Subject Property throughout the course of this Phase I ESA.

According to aerial photographs and city directory listings, the California Equine Retirement Foundation has occupied Parcel 2 since at least 2006.

On-site operations do not include the use of significant quantities of hazardous substances or petroleum products. The Subject Property area of Parcel 2 is vacant with no structures or notable features. No environmental issues were identified in association with current and historical horse ranch operations on Parcel 2.

5. Current Subject Property Conditions
A Roux representative conducted a reconnaissance of the Subject Property and surrounding areas on October 12 and 13, 2023. During the Subject Property visit, Roux representatives, Ms. Ashley Whitaker and Ms. Francine Cason, observed the Subject Property and adjoining properties from reasonably accessible locations on the Subject Property and public thoroughfares. During the site reconnaissance, the weather was clear, and the temperature was approximately 90° Fahrenheit. The following sections summarize observations during the inspection. Roux documented the site reconnaissance with photographs which are provided in Appendix G.

5.1 Site Reconnaissance
The Subject Property consists of a proposed irrigation channel alignment which traverses nine contiguous parcels along North Sanderson Avenue and Record Road (Figure 2). North Sanderson Avenue, a northsouth trending road, transects the Parent Property and is located east of Parcels 6 and 7 and west of Parcels 2 through 5. Record Road, an east-west trending road also transects the Paret Property and is located north of Parcels 6 through 8 and south of Parcel 9. A description of the use and/or operation of the Parent Property and each Subject Property area is provided below:
• Parcel 1 is developed with the western portion of the San Jacinto Reservoir. The Subject Property portion of Parcel 1 consists of berms and unpaved roadways. • Parcel 2 is developed as a retired horse ranch occupied by California Equine Retirement Foundation (805 North Sanderson Avenue). The Subject Property portion of Parcel 2 consists of a vacant area with no structures or notable features;
• Parcel 3, including the Subject Property portion, consists of vacant land; • Parcel 4, including the Subject Property portion, consists of an agricultural field (watermelon); • Parcel 5, including the Subject Property portion, consists of an agricultural field (unknown leafy crop); • Parcel 6, including the Subject Property portion, consists of an agricultural field (watermelon); • Parcels 7 and 8, including the Subject Property portions, consist of vacant land; and • Parcel 9, including the Subject Property portions, consists of an enclosed agricultural field (unknown crop) with greenhouse farming structures.

The adjoining properties are developed with agricultural land (row crops and dairy farm), residences, and the Jacinto Valley Regional Water Reclamation Plant.

5.2 Phase I ESA Observations
During the site reconnaissance, Roux personnel attempted to identify any environmental features that may be relevant in the context of the Phase I ESA. The features identified are summarized in the table below.

5.2.1 Former Agricultural Applied Pesticide Area
According to aerial photographs, agricultural operations (row crops) have been conducted on Parcels 3, 4, 5, 6, 7, and 8 (including Subject Property areas) since at least 1949. Parcel 9 appeared developed for agricultural use circa 1975 and again in 2023. At the time of Roux’s site reconnaissance, Parcel 4 was developed as a watermelon field, Parcel 5 was developed with a field (unknown leafy crops), and Parcel 6 was developed with a corn field. Parcels 3, 7, and 8 were vacant. Based on the long-term agricultural use, it is possible that agricultural chemicals, such as organochlorine, lead-based, and arsenic-based pesticides, herbicides, and fertilizers, may have been used on-site within Parcels 3 through 8. Previous site investigations conducted within Parcels 6, 7, and 8 did not identify significant evidence of soil contamination associated with historical crop growth. The potential for impacts from agricultural chemicals to on-site soils within Parcels 3, 4, 5, and 9 is considered a REC.

5.2.2 Pond(s)
The west adjoining dairy farm features several ponds, likely used to store dairy farm effluent including manure. At the time of the inspection, no water was observed in the ponds. The likely use of the adjoining dairy ponds for disposal of dairy farm effluent (including manure) is considered an other environmental feature (OEF) due to the potential for vapor migration of methane gas in soil vapor. The Subject Property is slated to be redeveloped with an irrigation channel with no structures, minimizing the concern for vapor intrusion to future occupants.

Concentrated animal feeding lots such as dairy farms can be a source of local groundwater degradation due to nitrates and total dissolved solids (TDS). The Subject Property and surrounding areas are not located within any known groundwater degradation areas affected by elevated nitrates and TDS. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 23

6. Vapor Migration and Intrusion
As recommended by ASTM E 1527-21 and ASTM E 2600-15 (Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions), Roux performed a vapor migration/intrusion pathway assessment in order to identify the presence or likely presence of chemicals of concern vapors from contaminated soil and/or groundwater either on or near the Subject Property.

The operation of the west adjoining property as a dairy farm constitutes a source for potential vapor intrusion due to possible methane buildup in shallow soils. The dairy farm operations have been identified elsewhere in this report as an OEF.

No other sources for potential vapor intrusion were identified for the Subject Property, Parent Property, or any other adjoining or nearby properties.

7. Summary of Key Previous Investigations
The following sections provide a summary of previous environmental investigations at select Parent Property parcels, including portions of the Subject Property. Previous environmental investigation reports are included in Appendix H.

Roux, on behalf of User, conducted previous Phase I ESAs and subsurface investigations of Parcels 7 and 8 in 2021 and Parcel 6 in 2023. The Phase I ESAs and subsurface investigations were prepared under separate covers; and previous environmental issues identified as RECs, hRECs, and/or OEFs with respect to Parcels 6, 7, and 8 were addressed in the subsurface investigations and are discussed in more detail in the following sections.

7.1 Draft Environmental Impact Report (Dudek, 2009)
Dudek prepared an Environmental Impact Report (EIR) for the City of San Jacinto for the proposed Villages of San Jacinto redevelopment project (the Site). The Site, as defined by Dudek in the 2009 EIR, included Parcels 7 and 8 as well the south adjoining parcel at 870 Sanderson Avenue). The Villages of San Jacinto project consisted of mixed-use redevelopment of the Site including parks, residences, and a high school.

Included in the EIR is a reference to a previous Phase I ESA prepared by Gradient Engineers, dated October 10, 2002 (2002 Phase I ESA). A copy of this report was not included in the appendices provided to Roux.

The following on-Site environmental hazards were identified in the EIR, particularly regarding the former agricultural operations and petroleum storage.
• Former Heifer Farm. A southeastern portion of the Site, totaling approximately 20 acres in size, was formerly developed as a heifer raising farm from at least 1978 through 2002. The former heifer farm operations represented a REC due to the possible presence of methane from manure.

According to the EIR, the Riverside County’s Methane Investigation Protocol would be followed in order to ensure that methane hazards did not exist on the 20-acre portion of the Site formerly used for heifer raising. Methane gas sampling and associated mitigation activities were reportedly planned after grading, in accordance with RCDEH protocols.

Roux note: The former heifer farm was located on the south adjoining parcel and is not considered a REC in the context of this Phase I ESA.
• Petroleum-Stained Soil. During the 2002 Phase I ESA, petroleum-stained soil was observed beneath a diesel aboveground storage tank (AST) located northwest of the reservoir (pond), near the irrigation groundwater well located southwest of the reservoir, and on the floor of the equipment shed, beneath three oil-containing 55-gallon drums. Based on the storage of hazardous substances and petroleum products in uncovered ground areas and evidence of a release, the former chemical storage identified above represented a REC. In order to evaluate and possibly mitigate environmental hazards associated with petroleum releases, the EIR recommended sampling and proper disposal of stained soils.

Roux note: The petroleum-stained soil area was located on the south adjoining parcel and is not considered a REC in the context of this Phase I ESA.
• Septic Systems. According to the EIR, the Site was equipped with two septic systems that historical sources suggest may have been in operation for many decades. The EIR stated the septic systems would be removed along with any residue material in accordance with RCDEH protocols. Based on the likely use of these systems for domestic waste only, the existing septic systems represent an OEF.
2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 25 Roux note: The locations of the septic systems were not identified or and are unlikely to be associated with disposal of hazardous substances or petroleum products. Any potentially on-site septic systems are not considered a REC in the context of this Phase I ESA. • Debris. Debris, including old equipment, water heaters, tires, and trash were observed in several piles throughout the site both in the 2002 Phase I ESA and during Site reconnaissance associated with the EIR. Several mounds of soil also were observed across the Site. According to the EIR, the soil piles were generated from on-Site activities and were piled for storage and eventual removal.

The EIR recommended a qualified environmental professional be present on-Site during removal of debris piles to assess debris and stockpiled soils and direct disposal accordingly. All debris would be disposed of in accordance with state and local laws. Based on observations made during the Site reconnaissance, on-Site debris represent an OEF.

Roux note: The location of the debris was not identified or and is unlikely to be associated with disposal of hazardous substances or petroleum products. Any potentially on-site debris is not considered a REC in the context of this Phase I ESA.

7.2 Phase I ESA (South Shore, 2021)
South Shore Testing and Environmental (South Shore) conducted a Phase I ESA of Parcel 6 in 2021 on behalf of the current property owner, Mr. J.D. Pierce. At the time of the assessment, the property was vacant agricultural land and proposed to be redeveloped for residential use. South Shore identified the potential presence of pesticides in soil from historical agricultural use as a REC and recommended further investigation.

Subsequent soil sampling conducted in Parcel 6 is discussed below.

7.3 Phase I ESA (Roux, 2021A)
Roux prepared a Phase I ESA of Parcels 7 and 8, and the south adjoining property at 870 Sanderson Avenue (Site). A review of historical sources indicated that Parcels 7 and 8 were developed for agricultural use, possibly row crops, by 1949 and remained until approximately 2012. By 1978, 20 acres on the southeastern portion of the site (south adjoining property) were developed with a heifer raising farm including corrals, water cisterns, and covered structures. No heifer or dairy farm operations were identified within Parcel 7 or 8.

Westra Dairy Farm, formerly located at 870 Sanderson Avenue, was identified as having a closed Leaking Underground Storage Tank (LUST) file. The closed LUST case is discussed in Section 7.1.2. Roux identified the remaining petroleum hydrocarbon-impacted soil in the former LUST area as a hREC in the 2021 Phase I ESA.

Other notable items of environmental concern identified for the south adjoining parcel at 870 North Sanderson Avenue include petroleum-stained soil was observed beneath a diesel aboveground storage tank (AST) located northwest of a reservoir (pond), near the irrigation groundwater well located southwest of the reservoir, and on the floor of the equipment shed, beneath three oil-containing 55-gallon drums.

Roux also noted an EnviroStor case, identified as the Proposed High School at the Villages of San Jacinto (Proposed High School), associated with Parcels 7 and 8 of the Parent Property. DTSC records for the Proposed High School indicate soil samples, composite surface soil samples, and discrete soil samples were collected and analyzed for metals and organochlorine pesticides in order to determine potential threat to public health and/or the environment related to former agricultural use. A letter of “No Further Action” was 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 26 given on September 24, 2008. Based on the “No Further Action” letter and the lack of additional investigation, the Proposed High School property was not considered an environmental concern in the context of the Phase I ESA. Based on the available information, Roux identified the former Heifer Farm, petroleum-stained soil, unlined pond, and former agricultural use as RECs.

Roux note: For the purposes of this Phase I ESA, the former agricultural use of the Site was the only REC appliable to Parcels 7 and 8. The remaining RECs apply to the south adjoining property at 870 North Sanderson Avenue and are not considered RECs in the context of this Phase I ESA.

7.4 Phase II Subsurface Investigation Letter Report (Roux, 2021B) Roux conducted Phase II a subsurface investigation on Parcels 7 and 8, and the south adjoining property at 870 Sanderson Avenue) to address environmental concerns identified by Roux in the 2021 Phase I ESA.

The scope of work attempted to address the following:
• Residual petroleum-impacted soil in the former UST area; • Potential petroleum impacts from former on-Site ASTs; • Potential volatile organic compounds, metals, pesticides, and total petroleum hydrocarbon (TPH), methane impacts from former on-Site heifer raising farm uses, including multiple livestock corrals and an unlined pond; and
• Potential pesticide impacts to shallow soils from former agricultural (row crop) uses.

Roux note: Potential pesticide impacts to shallow soils were the only environmental concerns located within the Subject Property. The remaining environmental concerns were located on the south adjoining property.

Investigation of the off-site environmental concerns is not discussed in detail as part of this Phase I ESA.

On September 1 and 2, 2021, a total of 184 soil samples were collected from 46 quadrants (SS-1 through SS-46) across the Site, including Subject Property areas, at a depth of 0.5 feet bgs. Soil sampling locations were evenly distributed in a grid pattern across each quadrant. Soil samples were composited into 46 samples (SS-COMP-1 through SS-COMP-46) and analyzed for lead and arsenic and organochlorine pesticides (OCPs).

In general, individual OCP constituents were detected in several quadrants including dichlorodiphenyldichloroethane (4,4’-DDD), dichlorodiphenyldichloroethylene (4,4’-DDE), dichlorodiphenyltrichloroethane (4,4’-DDT), and eldrin aldehyde. No OCPs were detected above applicable commercial/industrial screening levels.

Arsenic was detected at concentrations exceeding applicable regulatory screening levels; however, arsenic concentrations were below the upper range of regional background concentrations. Lead was not detected above regional background concentrations or applicable commercial/industrial screening levels.

Based on the results of this Phase II Subsurface Investigation, Roux determined that it had addressed the RECs identified in the Phase I ESA and did not recommend further investigation. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 27

7.5 Phase I ESA (Roux, 2023A)
Roux conducted a Phase I ESA of the Parcel 6 in 2023. The property was vacant agricultural land at the time of the time of the assessment. Roux considered the potential presence of impacted on-site soils based on the long-term use of agricultural chemicals, such as pesticides, herbicides, and fertilizers as a REC.

7.6 Phase II Subsurface Investigation Letter Report (Roux, 2023B) Roux conducted a Phase II investigation of a Parcel 6 in 2023 following the Phase I ESA which identified potential pesticide impacts to shallow soils from agricultural use as a REC. To address the identified environmental concern, Roux collected composite and discrete soil samples from 12 locations (quadrants) across the site to identify potential impacts in the shallow soil associated with historical agricultural use.

A total of 28 soil samples were collected from 12 quadrants, composited into 14 samples, and were analyzed for lead, arsenic, and OCPs.

No OCP constituents were reported at concentrations above their respective laboratory method reporting limits (MRLs). All MRLs were below applicable USEPA RSLs and/or DTSC HERO HHRA Note 3 for commercial/industrial soil.

The results of the Phase II subsurface investigation indicated that shallow soil OCP and select metals concentrations were below conservative regulatory thresholds for commercial/industrial land use and/or regional background concentrations. Roux concluded that the REC identified in the Phase I ESA was addressed and no further investigation was recommended. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 28

8. Database Records Review

8.1 Standard Environmental Record Sources
According to ASTM Standard E1527-21, the purpose of reviewing regulatory records is to obtain and review records that will help identify recognized environmental conditions in connection with the Subject Property.

In addition, some records to be reviewed pertain not only to the Subject Property, but also to properties within an additional “approximate minimum search distance” in order to help assess the likelihood of problems from migrating hazardous substances or petroleum products. The basis of the “approximate minimum search distance” is the Subject Property boundary.

Roux retained EDR of Shelton, Connecticut to provide ASTM Radius Map Reports (EDR Reports) for the Subject Property. Each report is a computerized search of select state and federal environmental databases that identify various properties with a record of environmental activity. Roux reviewed the reports and summarized the relevant findings in the following sections. Copies of the compiled EDR Reports have been included as Appendix F. The EDR reports include a detailed description of each of the databases searched, providing a summary of the type of information provided by each. A summary of Roux’ review of the EDR Report listings is provided in Table 1.

The following section describes the findings of the database search. Roux used professional judgement in determining which EDR-listed sites to include in the narrative of this report. Facilities adjoining the Subject Property were included due to their proximity to the Subject Property and the potential for surface water discharges (e.g., storm water runoff, surface water effluent discharges) to enter the Subject Property or through the migration of groundwater. Sites with listings indicative of a release (e.g., SHWS, LUST, RELEASE) are likewise discussed below. Non-adjoining facilities with database listings not necessarily indicative of a release (hazardous waste generator, FINDS, ECHO, NPDES, HAZNET, AST, or UST) will not be discussed unless considered potentially relevant in context of the Phase I ESA.

The Proposed High School at the Villages of San Jacinto (Proposed High School) was located in the northern portion of the Subject Property (Parcels 7 and 8) and is listed on the ENVIROSTOR, SCH, and CERS databases. Information associated with the Proposed High School case is discussed in Section 6.5.

The HWTS listing for Metropolitan Water District of Southern California is likely associated with the San Jacinto Reservoir facility (Parcel 1). The database listing was created in May 2018 and became inactive by August 2018. No additional information regarding the listing was available at the time of this assessment. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 29 No violations were noted on the database listing. Based on the lack of documented releases or violations, this listing is not considered an environmental concern in the context of this Phase I ESA.

The CERS database listings under the name of “San Jacinto Deteriorated Pole 2178000E Replacement” and “San Jacinto Reservoir Pump Station Pipeline” are associated with the operations conducted at the San Jacinto Reservoir facility (Parcel 1). No additional information regarding this listing was available in the EDR report. Based on the lack of documented releases or violations, these listings are not considered an environmental concern in the context of this Phase I ESA.

8.1.2 Adjoining and Nearby Properties
Discussions of adjoining and nearby properties of potential environmental concern as noted in Table 1 are provided below.
• Westra Dairy Farm (870 Sanderson Avenue). The former Westra Dairy Farm is located on a south adjoining property (south of Parcel 7) and is listed on the LUST, CORTESE, and CERS database.

The LUST database indicates there is a cleanup case for gasoline in soil. Under the direction of the County of Riverside, two 1,000-gallon USTs and one 10,000-gallon USTs were removed from the site in December 1999. Subsequent soil sampling was conducted and determined extent of the contamination was “very limited”, and the vertical extent reached below the former tanks to a depth of 35 feet. A mobile soil vapor extraction system was used to extract and treat soil vapor contamination in mid-2001. A “No Further Action” letter was issued by the SA-RWQCB to the Westra Family Trust on December 26, 2001. According to the “No Further Action” letter, data from this investigation indicated that the residual petroleum hydrocarbons in soil were limited to an area with a 15-foot radius between 15 and 20 feet bgs and did not indicate a significant presence or source of petroleum hydrocarbons in the soil. Roux performed additional soil and soil vapor sampling in the vicinity of the former USTs and did not identify significant impacts (Roux, 2021B). • San Jacinto Mobil (2070 North Sanderson Avenue). The San Jacinto Mobil facility is located approximately 0.5 mile northeast of the Subject Property and is listed on the LUST (Leaking Underground Storage Tank), CORTESE, and CERS databases. The LUST database indicates there is a cleanup case for diesel, gasoline, waste oil, motor oil, hydraulic oil, and lubricating oil in groundwater. According to groundwater monitoring reports, samples collected towards the direction of the Subject Property were non-detectable or had low detections of chemicals of concern (Leighton, 2009). On May 27, 2010, the facility was granted case closure by RCDEH. Due to the closure status and low detections, the San Jacinto Mobil facility is not considered an environmental concern in the context of the Phase I ESA.
• Betty Goedhart (2004 North Ramona Boulevard). The Betty Goedhart listing is associated with a property (approximately 0.20 mile west-northwest from the Subject Property) that appears to be an area utilized as a parking location for semi-trucks and trailers. According to the database listing, this facility is not a generator of hazardous waste of hazardous waste. The database listings notes that no violations were found for the facility. Based on the available information, this facility is not expected to be an environmental concern in the context of this Phase I ESA.

8.1.3 Orphan Sites
The EDR Report includes a section addressing “Orphan” sites. Orphan listings are sites, which, due to incomplete geographic location data, incomplete address information or incorrect address information, cannot be plotted correctly. The database reports identified one unmapped facility. Based on the relative distance to this facility, it is not considered a REC in the context of this Phase I ESA. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 30

Roux has performed this Phase I ESA in general compliance with the scope and limitations of ASTM Standard Practice E1527-21. Roux separated the findings of this assessment into the following four categories:
recognized environmental conditions, controlled recognized environmental conditions, historical recognized environmental conditions and other environmental features.

9.1 Data Gaps
During conduct of this ESA, the following data gaps, as defined in ASTM Standard E1527-21 were identified:
• Previous Subject Property owners/operators were not available for an interview. This data gap is not considered significant due to sufficient information regarding Subject Property history available from EDR historical documents and FOIA requests.

9.2 Recognized Environmental Conditions
Based on the information obtained through the performance of this ESA, Roux identified the following RECs in connection with the current and historical operations at the Subject Property or adjoining properties. To the extent possible, the locations of the RECs are shown in Figure 2. To avoid confusion, all RECs, cRECs, hRECs, and OEFs are numbered sequentially.

9.3 Controlled Recognized Environmental Conditions
Roux did not identify known or suspected cRECs in connection with the current and historical operations at the Subject Property or adjoining properties.

9.4 Historical Recognized Environmental Conditions
Roux did not identify known or suspected hRECs in connection with the current and historical operations at the Subject Property or adjoining properties.

9.5 Other Environmental Features
Based on the information obtained through the performance of this ESA, Roux identified the following OEFs in connection with the current and historical operations at the Subject Property or adjoining properties.

OEF 2 – Adjoining Dairy Ponds. The west adjoining dairy farm features several ponds, likely used to store dairy farm effluent including manure. At the time of the inspection, no water was observed 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 31 in the ponds. The likely use of the adjoining dairy ponds for disposal of dairy farm effluent (including manure) is considered an OEF due to the potential generation and migration of methane gas. The Subject Property is slated to be redeveloped with an irrigation channel with no structures, minimizing the concern for gases beneath future inhabited buildings or structure. 2217.0031L100/R Phase I Environmental Site Assessment | ROUX | 32

Glossary of Terms
Phase I Environmental Site Assessment | ROUX | 1

GLOSSARY OF KEY TERMS
This appendix provides definitions, description of terms, and a list of acronyms for many of the words used in ASTM E 1527-21. These terms are an integral part of ASTM E 1527-21 and are critical to understanding ASTM E 1527-21 and its use.

DEFINITIONS:

Abandoned Property – property that can be presumed to be deserted, or an intent to relinquish possession or control can be inferred from the general disrepair or lack of activity thereon such that a reasonable person could believe that there was an intent on the part of the current owner to surrender rights to the property.

Activity and Use Limitations – Legal or physical restrictions or limitations on the use of, or access to, a site or facility: (1) to reduce or eliminate potential exposure to hazardous substances or petroleum products in the soil, soil vapor, groundwater, and/or surface water on the property, or (2) to prevent activities that could interfere with the effectiveness of a response action, in order to ensure maintenance of a condition of no significant risk to public health or the environment. These legal or physical restrictions, which may include institutional and/or engineering controls, are intended to prevent adverse impacts to individuals or populations that may be exposed to hazardous substances and petroleum products in the soil, soil vapor, groundwater, and/or surface water on a property.

Construction debris, n – Concrete, brick, asphalt, and other such building materials discarded in the construction of a building or other improvement to property.

Contaminated public wells, n – Public wells used for drinking water that have been designated by a government entity as contaminated by toxic substances (for example, chlorinated solvents,) or petroleum products, or as having water unsafe to drink without treatment.

Contiguous Property Owner [42 U.S.C. Section 9607 (q)], n– a person may qualify for the contiguous property owner liability protection if, among other requirements, such person owns real property that is contiguous to, and that is or may be contaminated by hazardous substances from other real property that is not owned by that person. Furthermore, such person conducted all appropriate inquiries at the time of acquisition of the subject property and did not know or have reason to know that the subject property was or could be contaminated by a release or threatened release from the contiguous property. The all appropriate inquiries must not result in knowledge of contamination. If it does, then such person did “know” or “had reason to know” of contamination and would not be eligible for the contiguous property owner liability protection. See appendix C1 for the other necessary requirements that are beyond the scope of this practice.

Controlled Recognized Environmental Condition, n – a recognized environmental condition affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations). For examples of controlled recognized environmental conditions, see Appendix X4.

Data failure, n – failure to achieve the historical research objective in 8.3.1 even after reviewing the standard historical resources in 8.3.4.1 through 8.3.4.8 that are reasonably ascertainable and likely to be useful. Data failure is on type of data gap.

Data gap, n – a lack of or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information. Data gaps may result from incompleteness in Phase I Environmental Site Assessment | ROUX | 2
any of the activities required by this practice, including, but not limited to, site reconnaissance (for example, an inability to conduct the site visit), and interviews (for example. An inability to interview the key site manager, regulatory officials, etc.). See 12.6.
de minimis condition, n – a condition related to a release that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. A condition determined to be a de minimis condition is not a recognized environmental condition nor a controlled recognized environmental condition.

Demolition debris, n – Concrete, brick, asphalt, and other such building materials discarded in the demolition of a building or other improvement to a property.

Drum, n – A container (typically, but not necessarily, holding 55 gal (208 L) of liquid) that may be used to store hazardous substances or petroleum products.

Dry wells, n – Underground areas where soil have been removed and replaced with pea gravel, coarse sand, or large rocks. Dry wells are used for drainage, to control storm runoff, for the collection of spilled liquids (intentional and non-intentional), and wastewater disposal (often illegal).Dwelling, n – Structure of portion thereof used for residential habitation.

Engineering controls, n – Physical modifications to a site or facility (for example, capping, slurry walls, or point of use water treatment) to reduce or eliminate the potential for exposure to hazardous substances or petroleum products contaminants in the soil or groundwater on the property.

Environment, n – environment shall have the same meaning as the definition of environment in CERCLA 42 U.S.C. Section 9601(8), For additional background information, see Legal Appendix (Appendix X1) to X1.1.1 “Releases.”
Environmental Compliance audit, n – the investigative process to determine if the operations of an existing facility are in compliance with applicable environmental laws and regulations. This term should not be used to describe this practice, although an environmental compliance audit may include an environmental site assessment or, if prior to audit are available, may be part of an environmental site assessment.

Environmental lien, n – A charge, security, or encumbrance upon title to a property to secure the payment of a cost, damage, debt, obligation, or duty arising out of response actions, cleanup, or other remediation of hazardous substances or petroleum products upon a property, including (but not limited to) liens imposed pursuant to CERCLA 42 USC § 9607(1) & 9607(r) and similar state or local laws.

Environmental professional, n – a person meeting the education, training, and experience requirements as set forth in 40 C.F.R. § 312.10(b). For the convenience of the reader, this section is reprinted in Appendix X2. The person may be an independent contractor or an employee of the user.ERNS list, n – EPA’s emergency response notification system list of reported CERCLA hazardous substance releases or spills in quantities greater than the reportable quantity, as maintained at the National Response Center.

Furthermore, the all appropriate inquiries must not have resulted in knowledge of the contamination. If it does, then such person did “known” or “had reason to know” of contamination and would not be eligible for the innocent landowner defense. See Appendix X1 for the other necessary requirements that are beyond the scope of this practice.

Institutional controls (IC), n – A legal or administrative mechanism (e.g., deed restriction, restrictive zoning) on the use of, or access to, a site or facility to (1) reduce or eliminate potential exposure to hazardous substances or petroleum products in the soil or groundwater on the property, Of (2) to prevent activities that could interfere with the effectiveness of a response actions, in order to ensure maintenance of a condition of no significant risk to public health of the environment. An institutional control is a type of activity and use limitation (AUL).

DEFINITIONS SPECIFIC TO ASTM E 1527-21:

Actual knowledge, n – The knowledge actually possessed by an individual who is a real person, rather than an entity. Actual knowledge is to be distinguished from constructive knowledge that is knowledge imputed to an individual or entity.

Phase I Environmental Site Assessment | ROUX | 7
Adjoining properties – Any real property or properties the border of which is contiguous or partially contiguous with that of the property, or that would be contiguous or partially contiguous with that of the property but for a street, road, or other public thoroughfare separating them.

Aerial photographs, n – Photographs taken from an airplane or helicopter (from a low enough altitude to allow identification of development and activities) of areas encompassing the property. Aerial photographs are often available from government agencies or private collections unique to a local area.

Appropriate inquiry, n – That inquiry constituting “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined in CERCLA, 42 USC § 9601(35)(B), that will give a party to a commercial real estate transaction the innocent landowner defense to the CERCLA liability (42 USC § 9601(A) and (B) and § 9607(b)(3)), assuming compliance with other elements of the defense. See Appendix X1.

Approximate minimum search distance, n – The area for which records must be obtained and reviewed pursuant to Section 7 subject to the limitations provided in that section. This may include areas outside the property and shall be measured from the nearest property boundary. This term is used in lieu of radius to include irregularly-shaped properties.

Building department records, n – Those records of the local government in which the property is located indicating permission of the local government to construct, alter, or demolish improvements on the property.

Often, building department records are located in the building department of a municipality or county.

Business environmental risk, n – A risk which can have a material environmental or environmentally-driven financial impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated in this practice.

Consideration of business environmental risk issues may necessitate that an environmental professional address one or more non-scope considerations, some of which are identified in Section 12.

Commercial real estate, n – Any real property except a dwelling or property with no more than four dwelling units exclusively for residential use (except that a dwelling or property with no more than four dwelling units exclusively for residential use is included in this term when it has a commercial function, as in the building of such dwellings for profit). This term includes, but is not limited to, undeveloped real property and real property used for industrial, retail, office, agricultural, other commercial, medical, or educational purposes; property used for residential purposes that has more than four residential dwelling units; and any property with no more than four dwelling units for residential use when it has a commercial function, as in the building of such dwellings for profit.

Commercial real estate transaction, n – A transfer of title to or possession of real property or receipt of a security interest in real property, except that it does not include transfer of title to or possession of real property or the receipt of a security interest in real property with respect to an individual dwelling or building containing fewer than five dwelling units, nor does it include the purchase of a lot or lots to construct a dwelling for occupancy by a purchaser, but a commercial real estate transaction does include real property purchased or leased by persons or entities in the business of building or developing dwelling units.

Phase I Environmental Site Assessment | ROUX | 8
Due diligence, n – the process of inquiring into the environmental characteristics of a commercial real estate or other conditions, usually in connection with a commercial real estate transaction. The degree and kind of due diligence vary for different properties, and differing purposes. See Appendix X1.

Environmental audit, n – The investigative process to determine if the operations of an existing facility are in compliance with applicable environmental laws and regulations. This term should not be used to describe Practice E 1528 or this practice, although an environmental audit may include an environmental site assessment or, if prior audits are available, may be part of an environmental site assessment.

Environmental professional, n – A person processing sufficient training and experience necessary to conduct a site reconnaissance, interviews, and other activities in accordance with this practice, and from the information generated by such activities, having the ability to develop opinions and conclusions regarding recognized environmental conditions in connection with the property in question. An individual’s status as an environmental professional may be limited to the type of assessment to be performed or to specific segments of the assessment for which the professional is responsible. The person may be an independent contractor or an employee of the user.

Environmental site assessment (ESA), n – the process by which a person or entity seeks to determine is a subject property is subject to recognized environmental conditions. At the option of the user, an environmental site assessment may include more inquiry than that constituting all appropriate inquiries or, if the user is not concerned about qualifying for the LLPs, less inquiry than that constituting all appropriate inquiries. An environmental site assessment is both different from and often less rigorous than an environmental compliance audit.

Fill dirt, n – dirt, soil, sand, or other earth, that is obtained off-site, that is used to fill holes or depressions, create mounds, or otherwise artificially change the grade or elevation of real property. It does not include material that is used in limited quantities for normal landscaping activities.

Hazardous waste/contaminated sites, n – Sites on which a release has occurred, or is suspected to have occurred, of any hazardous substance, hazardous waste, or petroleum products, and that release or suspected release has been reported to a government entity.

Historical Recognized Environmental Condition, n – a previous release of any hazardous substances or petroleum products affecting the subject property that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the subject property to any controls (for example, activity and use limitations, or other property use limitations). A historical recognized environmental condition is not a recognized environmental condition. For examples of historical recognized environmental conditions, see Appendix X4.

Innocent landowner defense – That defense to CERCLA liability provided in 42 USC § 9601(35) and § 9607(b)(3). One of the requirements to qualify for this defense is that the party make “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice.” There are additional requirements to qualify for this defense.

Interviews, n – those portions of this practice that are conducted to gather information from an individual or individuals in person, by telephone, in writing, or via other electronic media to meet the objectives of this practice.

Phase I Environmental Site Assessment | ROUX | 9
Key site manager, n – The person identified by the owner of a property as having good knowledge of the uses and physical characteristics of the property.

Local government agencies, n – Those agencies of municipal or county government having jurisdiction over the property. Municipal and county government agencies include, but are not limited to, cities, parishes, townships, and similar entities.

LUST sites, n – State lists of leaking underground storage tank sites. Section 9003 (h) of Subtitle I of RCRA gives EPA and states, under cooperative agreements with EPA, authority to clean up releases from UST systems or require owners and operators to do so.

Major occupants, n – Those tenants, subtenants, or other persons or entities each of which uses at least 40% of the leasable area of the property or any anchor tenant when the property is a shopping center.

Material threat, n – Obvious threat which is likely to lead to a release and that, in the opinion of the environmental professional, would likely result in impact to public health or the environment. An example might include an aboveground storage tank system that contains s hazardous substance and which shows evidence of damage. The damage would represent a material threat if it is deemed serious enough that it may cause or contribute to tank integrity failure with a release of contents to the environment.

Obvious, adj – That which is plain or evident; a condition or fact that could not be ignored or overlooked by a reasonable observer while visually or physically observing the property.

Other historical sources, n – Any source or sources other than those designated in 7.3.4.1-7.3.4.8 that are credible to a reasonable person and that identify past uses of the property. The term includes, but is not limited to, miscellaneous maps, newspaper archives, and records in the files and/or personal knowledge of the property owner and/or occupants.

Physical setting sources, n – Resources that provide information about the geologic, hydrogeologic, hydrologic, or topographic characteristics of the area that includes the subject property.

Practically reviewable, adj – Information that is practically reviewable means that the information is provided by the source in a manner and in a form that, upon examination, yield information relevant to the subject property without the need for extraordinary analysis of irrelevant data. The form of the information shall be such that the user can review the records for a limited geographic area. Records that cannot be feasibly retrieved by reference to the location of the subject property or a geographic area in which the subject property is located are not generally practically reviewable. Most databases of public records are practically reviewable if they can be obtained from the source agency by the county city, zip code, or other geographic area of the facilities listed in the record system. Records that are sorted, filed, organized, or maintained by the source agency only chronologically are not generally practically reviewable. Listings in publicly available records which do not have adequate address information to be located geographically are not generally considered practically reviewable. For large databases with numerous records (such as RCRA hazardous waste generator and registered underground storage tanks), the records are not practically reviewable unless they can be obtained from the source agency in the smaller geographic area of zip codes. Even when information is provided by zip code for some large databases, it is common for an unmanageable number of sites to be identified within a given zip code. In these cases, it is not necessary to review the impact of all if the site that are likely to be listed in any given zip code because that information cannot be feasibly reviewed regarding its impact on the subject property, it is not practically reviewable.

Phase I Environmental Site Assessment | ROUX | 10
Preparer, n – The person preparing the transaction screen questionnaire pursuant to Practice E 1528, who may be either the user or the person to whom the user has delegated the preparation of the transaction screen questionnaire.

Publicly available, adj – Information that is publicly available means that the source of the information allows access to the information by anyone upon request.

Reasonably ascertainable, adj – Information that is (1) publicly available, (2) obtainable from its source within reasonable time and cost constraints, and (3) practically reviewable.

Recognized Environmental Conditions, n – (1) the presence of hazardous substances or petroleum products in, on, or at the subject property due to a release to the environment; (2) the likely presence of hazardous substances or petroleum products in, on, or at the subject property due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that pose a material threat of a future release to the environment.

Records review, n – That part that is contained in Section 8 of this practice addresses which records shall or may be reviewed.

Site reconnaissance, n – That part that is contained in Section 9 of this practice and addresses what should be done in connection with the site visit. The site reconnaissance includes, but is not limited to, the site visit done in connection with such a Phase I Environmental Site Assessment Site visit, n – The visit to the subject property during which observations are made constituting the site reconnaissance section of this practice.

Standard environmental record sources, n – Those records specified in 8.2.2.

Standard historical sources, n – Those sources of information about the history of uses of the property specified in 8.3.4.

Standard physical setting source, n – A current USGS 7.5-minute topographic map (if any) showing the area on which the property is located.
