5 PALEONTOLOGICAL SENSITIVITY
The fossil record is unpredictable, and the preservation of organic remains is rare, requiring a particular sequence of events involving physical and biological factors. Skeletal tissue with a high percentage of mineral matter is the most readily preserved within the fossil record; soft tissues not intimately connected with the skeletal parts, however, are the least likely to be preserved (Raup and Stanley 1978). For this reason, the fossil record contains a biased selection not only of the types of organisms preserved but also of certain parts of the organisms themselves. As a consequence, paleontologists are unable to know with certainty, the quantity of fossils or the quality of their preservation that might be present within any given geologic unit.

Sedimentary units that are paleontologically sensitive are those geologic units (mappable rock formations) with a high potential to contain significant nonrenewable paleontological resources.

More specifically, these are geologic units within which vertebrate fossils or significant invertebrate fossils have been determined by previous studies to be present or are likely to be present. These units include, but are not limited to, sedimentary formations that contain significant paleontological resources anywhere within their geographical extent as well as sedimentary rock units temporally or lithologically amenable to the preservation of fossils.

A geologic formation is defined as a stratigraphic unit identified by its lithic characteristics (e.g., grain size, texture, color, and mineral content) and stratigraphic position. There is a direct relationship between fossils and the geologic formations within which they are enclosed and, with sufficient knowledge of the geology and stratigraphy of a particular area, it is possible for paleontologists to reasonably determine the formation’s potential to contain significant nonrenewable vertebrate, invertebrate, marine, or plant fossil remains.

The paleontological sensitivity for a geologic formation is determined by the potential for that formation to produce significant nonrenewable fossils. This determination is based on what fossil resources the particular geologic formation has produced in the past at other nearby locations.

Determinations of paleontologic sensitivity must consider not only the potential for yielding vertebrate fossils but also the potential of yielding a few significant fossils that may provide new and significant taxonomic, phylogenetic, and/or stratigraphic data.

The Society of Vertebrate Paleontology issued a set of standard guidelines intended to assist paleontologists to assess and mitigate any adverse effects/impacts to nonrenewable paleontological resources. The guidelines defined four categories of paleontological sensitivity for geologic units that might be impacted by a proposed project, as listed below (Society of Vertebrate Paleontology 2010:1-2):
• High Potential: Rock units from which vertebrate or significant invertebrate, plant, or trace fossils have been recovered.
• Undetermined Potential: Rock units for which little information is available concerning their paleontological content, geologic age, and depositional environment. • Low Potential: Rock units that are poorly represented by fossil specimens in institutional collections, or based on general scientific consensus only preserve fossils in rare circumstances. • No Potential: Rock units that have no potential to contain significant paleontological resources, such as high-grade metamorphic rocks and plutonic igneous rocks. 2312
6 SETTING
The proposed project is located in the northern portion of the Peninsular Ranges province, which is bounded on the north by the Transverse Ranges province, on the northeast by the Colorado Desert province, and on the west by the Pacific Ocean (Jenkins 1980:40-41; Harms 1996:150). More specifically, the project area lies within the Santa Ana River Valley portion of the Peninsular Ranges province, a structurally depressed trough filled with sediments of Miocene through Recent age (Clarke 1978-1979:15).

The Santa Ana River Valley is one of the many tectonically controlled valleys within the valley-andridge systems found in the Perris Block. Defined by English (1926) as a region between the San Jacinto and Elsinore-Chino fault zones, the Perris Block is bounded on the north by the Cucamonga (San Gabriel) Fault and on the south by a vaguely delineated boundary near the southern end of the Temecula Valley. This structural block is considered to have been active since Pliocene time (Woodford et al. 1971:3421). The Pliocene- and Pleistocene-age non-marine sedimentary rocks filling the valley areas have produced a few vertebrate fossils, as well as a few invertebrate fossil remains (Mann 1955:13).

The L-shaped project area is situated on the western edge of the Eastvale city limits, wrapping around the northern and eastern sides of a formerly rural residential property at the northeastern corner of Hellman Avenue and Walters Street. It is surrounded by suburban residential neighborhoods on the west, north, and east, with the Rondo Elementary School of Discovery across Walters Street to the south. Elevations within the project boundaries range approximately from 573 feet to 582 feet above mean sea level, and the terrain is relatively level with a slight incline towards the north. Vegetation observed on the property includes grasses throughout, with large California pepper trees in the center of the project area. Also present on the property are several debris mounds with various types of domestic refuse (Figure 4).

7 METHODS AND PROCEDURES

RECORDS SEARCH
On December 3, 2025, CRM TECH requested paleontological records searches on this property from the San Bernardino County Museum (SBCM) in Redlands and the Western Science Center (WSC) in Hemet. These institutions maintain files of regional paleontological localities as well as supporting maps and documents. The records search results are used to identify known previously performed paleontological resource assessments as well as known paleontological localities within a one-mile radius of the project area. The SBCM provided the records search results in a letter dated January 9, 2026, but the WSC was unable to process the records search request in time. A copy of the records search results from the SBCM is attached to this report in Appendix 2.

LITERATURE REVIEW
In conjunction with the records searches, CRM TECH report writer Elizabeth Beckner reviewed geological literature pertaining to the project vicinity under the direction of principal paleontologist Ron C. Schmidtling. Sources consulted during this part of the research include primarily topographic, geologic, and soil maps and historical aerial/satellite photographs of the surrounding region, published geologic literature pertaining to the project location, and other materials in the CRM TECH library, including unpublished reports produced during similar surveys on nearby properties.

FIELD SURVEY
On December 17, 2025, CRM TECH paleontological surveyor Melissa Portilla carried out the field survey of the project area under Ron Schmidtling’s direction. The survey was completed by walking a series of parallel east-west transects spaced 15 meters (approximately 50 feet) apart. In this way, the ground surface in the entire project area was systematically and carefully examined to determine the soil types, to verify the geological formations, and to look for any indications of paleontological remains. Visibility of the native soils was poor (0-5%) in most of the project area because the ground was obscured by dense vegetation. In the areas with some exposed soils, mainly underneath the trees, visibility was fair (5-10%), although much of the ground was covered in a layer of dead vegetation. Considering the history of past disturbances to the ground surface within the project area, the level of visibility was deemed to be acceptable for the purpose of this study.

RESULTS AND FINDINGS

RECORDS SEARCH
The paleontological resources records search by the SBCM identified no known vertebrate paleontological localities within the project area. However, the SBCM reported four fossil localities that produced fossils of Bison sp. and Camelidae less than half a mile northeast of the project location (Kottkamp 2026; see Appendix 2). According to the SBCM, all four localities are assigned to Qoa, or “fluvial, mottled, brown-green silty clay or green-brown clayed sand,” while the surface sediments within the majority of the project area consist of Qyfa, or “young alluvial fan deposits of 2314
8 early Holocene and late Pleistocene age (ibid.). Older alluvial deposits occur nearby and may underlie the Qyfa surface sediments found within the project area (ibid.). The SBCM did not offer recommendations regarding the proposed project but noted that “Pleistocene age sediments commonly underlie surface deposits by 5 feet or less in northwestern Riverside County and are often fossiliferous” (ibid.).

LITERATURE REVIEW
Rogers (1965) maps the surface geology at the project location Qal (alluvium of Recent age). Knecht (1971:Map Sheet 22) maps the surface soil within the project area as Ce (Chino silt loam, drained).

Morton and Gray (2002) map the surface geology as Qyfa, described as young alluvial fan deposits from the Holocene and late Pleistocene that are “gray-hued sand and cobble- and gravel-sand deposits derived from lithic diverse sedimentary units” (Figure 5). Morton and Miller (2006) map the surface geology in the project area as Qyf3a, young alluvial-fan deposits from Unit 3 that date to the middle Holocene and is defined as “slightly to moderately consolidated silt, sand, and coarsegrained sand to bouldery alluvial-fan deposits having slightly to moderately dissected surfaces.” Historical aerial and satellite photographs indicate that land use in the project vicinity was dominated by agriculture, with cultivated fields and orchards occupying most of the land, until the post-WWII era (NETR 1938-1980). The project area evidently remains undeveloped until 1980, when the southeastern portion of the property was graded and a metal holding pen was constructed along Walters Street (NETR 1980). By 1985, the majority of the project area had been graded (NETR 1985). A building was constructed on the property during the 1990s but was removed in recent years, while the rest of the land was used for the storage of large trucks and shipping containers (NETR 1994-2022; Google Earth 2023-2025).

FIELD SURVEY
The field survey yielded negative findings for potential paleontological resources, and no surficial indications of any fossil remains were observed within or adjacent to the project area. Field observations confirmed that the ground surface in the project area has been extensively disturbed by past development since the 1980s. Today, it is littered with piles of debris and refuse, with some remnants of the development still present, such as the holding pen, a ramp, an asphalt drive, and a concrete walkway.

CONCLUSION AND RECOMMENDATIONS
CEQA guidelines (Title 14 CCR App. G, Sec. V(c)) require that public agencies in the State of California determine whether a proposed project would “directly or indirectly destroy a unique paleontological resource” during the environmental review process. The present study, conducted in compliance with this provision, is designed to identify any significant, nonrenewable paleontological resources that may exist within or adjacent to the project area and to assess the possibility for such resources to be encountered in future excavation and construction activities.

In summary of the research results outlined above, the surface sediments in the project area are relatively recent in age and have been extensively disturbed over the past few decades. Therefore, 2315
9 Figure 5. Geologic map of the project area. Based on Morton and Gray 2002 and Dibblee 2001. 2316
10 they are considered to be low in potential for significant nonrenewable paleontological resources.

However, the surface sediments likely overlie older alluvial deposits of Pleistocene age, which are high in paleontological sensitivity. While no vertebrate fossil localities have been identified in the immediate vicinity of the project area, fossil remains have been recovered nearby from the alluvium and rock sequences that also occur subsurface in and around the project area.

Based on these findings, CRM TECH recommends that a paleontological resource impact mitigation program be developed and implemented during the project to prevent project impact on significant, nonrenewable paleontological resources or reduce such impact to a level less than significant. As the primary component of the mitigation program, paleontological monitoring should be required during all earth-moving operations in sediments identified as likely to contain fossil remains. The mitigation program should be developed in accordance with the provisions of CEQA as well as the proposed guidelines of the Society of Vertebrate Paleontology (2010), and should include but not be limited to the following components:
• Earth-moving operations reaching beyond the depth of two feet should be monitored by a qualified paleontological monitor. The monitor should be prepared to quickly salvage fossils as they are unearthed to avoid construction delays and should collect samples of sediments that are likely to contain fossil remains of small vertebrates or in vertebrates. However, the monitor must have the power to temporarily halt or divert grading equipment to allow for the removal of abundant or large specimens.
• Collected samples of sediment should be processed to recover small fossils, and all recovered specimens should be identified and curated at a repository with permanent retrievable storage. • A report of findings, including an itemized inventory of recovered specimens, should be prepared upon completion of the procedures outlined above. The report should include a discussion of the significance of the paleontological findings, if any. The report and the inventory, when submitted to the City of Eastvale, would signify completion of the program to mitigate potential impacts on paleontological resources.

1.0 EXECUTIVE SUMMARY
Stantec Consulting Services Inc. (Stantec) has completed a Phase I Environmental Site Assessment (ESA) report of the property associated with Assessor’s Parcel Numbers (APNs) 144-070-016; 144-070- 017; 144-070-018; and 144-070-020, located at 7500 Hellman Avenue, northeast of the intersection of Hellman Avenue and Walters Street, Eastvale, Riverside County, California 92880 (the “Subject Property”), on behalf of Warmington Residential (the “Client”). The work was performed according to Stantec’s proposal and terms and conditions dated April 7, 2025. Warmington Residential (the “User”) has been designated as the User of this report. The intended use of this Phase I ESA is for due diligence in support of potential redevelopment.

The Phase I ESA was conducted in conformance with the requirements of ASTM International (ASTM) Designation E1527-21, and All Appropriate Inquiries (AAI) as defined by the United States Environmental Protection Agency (EPA) in Title 40 of the Code of Federal Regulations, Part 312 (40 CFR 312), except as may have been modified by the scope of work, and terms and conditions, requested by the Client. Any exceptions to, or deletions from, the ASTM or AAI practice are described in Section 2.3.

The Subject Property consists of approximately 3.2 acres of land associated with APNs 144-070-016; 144-070-017; 144-070-018; and 144-070-020, located at 7500 Hellman Avenue, northeast of the intersection of Hellman Avenue and Walters Street, Eastvale, Riverside County, California 92880. The Subject Property is currently vacant land. Adjoining properties, as well as the nearby area, include a concrete drainage channel to the north followed by residential structures; residential structures to the east and west; and an elementary school to the south. A Subject Property Location Map is provided as Figure

1. A Subject Property Vicinity Map illustrating the main features of the Subject Property and vicinity is provided as Figure 2. Photographs taken during the site reconnaissance visit are provided in Appendix A.

Based on review of historical sources including aerial photographs and city directory listings, the Subject Property was formerly utilized for livestock holding and a storage area of the trucks and trailers used in the transportation of livestock. During the site reconnaissance, a former cattle pen was observed in the southern portion of the Subject Property along Walters Avenue. Based on the historic aerial photographs and public record the property does not appear to have been used as a dairy or for any holding of cows and no signs of significant quantities of animal waste was observed. However, debris piles with various household debris, used tires, and building demolition waste were also observed in the center of the Subject Property.

As discussed in the following text in section 4.2.2 Rondo Elementary School south-southwest of the subject Property was a former dairy. An assessment of that property did not identify methane related to the former dairy’s operations. The Department of Toxic Substances Control (DTSC) oversaw the assessment of that property and determined that no issues exist to affect the development of the property into a school. There does not appear that any neighboring properties or the history of the subject Site would draw concern for the presence of methane that would affect the residential development of this Property.

Additionally, during the site reconnaissance, an irrigation well was observed in the northern portion of the Subject Property. The presence of an irrigation well is not considered an environmental concern to the 2330

Subject Property, however, if the well is not going to be used in the future it should be decommissioned in accordance with applicable regulatory requirements before grading activities occur.

We have performed a Phase I ESA in conformance with the scope and limitations of ASTM Practice E1527-21 of the Subject Property. Any exceptions to, or deletions from, this practice are described Section 2.3 of this report. This assessment has revealed no recognized environmental conditions (RECs), Controlled RECs (CRECs), or significant data gaps in connection with the Subject Property. No further investigation appears to be warranted at this time.

This assessment has revealed the following items of note in connection with the Subject Property:
• Debris piles with various household debris, used tires, and building demolition waste were also observed in the center of the Subject Property. The discarded building materials should be tested for the presence of asbestos-containing materials (ACMs) before off-site disposal in accordance with applicable federal and local regulations. • Additionally, during the site reconnaissance, an irrigation well was observed in the northern portion of the Subject Property. The presence of an irrigation well is not considered an environmental concern to the Subject Property, however, if the well is not going to be used in the future it should be decommissioned in accordance with applicable regulatory requirements before grading activities occur.

Project No.: 185806936 2.1

2.0 INTRODUCTION
The objective of this Phase I ESA was to perform AAI into the past ownership and uses of the Subject Property consistent with good commercial or customary practice as outlined by ASTM International (ASTM) in “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,” Designation E1527-21. “All Appropriate Inquiries” is the process for evaluating a property’s environmental conditions for the purpose of qualifying for landowner liability protections under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) following final rule of Part 312 of Title 40, Code of Federal Regulations (40 CFR Part 312). The purpose of this Phase I ESA was to identify, to the extent feasible, adverse environmental conditions including recognized environmental conditions (“RECs”) of the Subject Property.

The ASTM E1527-21 standard indicates that the goal of the Phase I ESA is to identify RECs, as well as historical recognized environmental conditions (“HRECs”) and controlled recognized environmental conditions (“CRECs”) that may exist at a property. The term “recognized environmental conditions” is defined as:
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.

ASTM defines a “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 and meets current unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (e.g., activity and use limitations or other property use limitations). A HREC is not considered a REC.

ASTM defines a “CREC” as a REC resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (e.g., as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), but with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (e.g., activity and use limitations, institutional controls, or engineering controls).

As defined by ASTM, RECs can include hazardous substances or petroleum products present under conditions in compliance with laws if that presence represents a material threat of future release. The release of hazardous substances or petroleum products is, however, not a REC if that presence is a de minimis condition. De minimis conditions are minor releases that generally do not present a material risk to human health and would not likely be subject to enforcement action if brought to the attention of governmental agencies. ASTM also considers the potential for a business environmental risk (BER), 2332

Project No.: 185806936 2.2
defined as a risk which can have a material environmental or environmentally driven impact on the business associated with the current or planned use of the Subject Property, not necessarily limited to those environmental issues required to be investigated by the ASTM standard. Consideration of BERs may involve addressing one or more ASTM non-scope considerations.

This Phase I ESA was conducted in accordance with our proposal to Warmington Residential dated April 7, 2025. The scope of work conducted during this Phase I ESA consisted of a visual reconnaissance of the Subject Property, interviews with key individuals, and review of reasonably ascertainable documents.

The scope of work did not include an assessment for environmental regulatory compliance of any facility ever operated at the Subject Property (past or present), or sampling and analyzing of environmental media. Stantec was not contracted to perform an independent evaluation of the purchase or lease price of the Subject Property and its relationship to current fair market value. The conclusions presented in this Phase I ESA report are professional opinions based on data described herein. The opinions are subject to the limitations described in Section 2.3.

ASTM E1527-21 notes that the availability of record information varies from source to source. The User or Environmental Professional (EP) is not obligated to identify, obtain, or review every possible source that might exist with respect to a property. Instead, ASTM identifies record information that is reasonably ascertainable from standard sources. “Reasonably ascertainable” means:

1. Information that is publicly available;

2. Information that is obtainable from its source within reasonable time and cost constraints; and

3. Information that is practicably reviewable.

2.1 SUBJECT PROPERTY DESCRIPTION
The Subject Property consists of approximately 3.2 acres of land associated with APNs 144-070-016; 144-070-017; 144-070-018; and 144-070-020, located at 7500 Hellman Avenue, northeast of the intersection of Hellman Avenue and Walters Street, Eastvale, Riverside County, California 92880. The Subject Property is currently vacant land. Adjoining properties, as well as the nearby area, include a concrete drainage channel to the north followed by residential structures; residential structures to the east and west; and an elementary school to the south. A Subject Property Location Map is provided as Figure

2.3 EXCEPTIONS AND LIMITING CONDITIONS
This report documents work that was performed in accordance with generally accepted professional standards at the time and location in which the services were provided and given the schedule and budget constraints established by the client. No other representations, warranties, or guarantees are made concerning the accuracy or completeness of the data or conclusions contained within this report, including no assurance that this work has uncovered all potential and actual liabilities and conditions associated with the Subject Property.

This report provides an evaluation of selected environmental conditions associated with the Subject Property that was assessed at the time the work was conducted and is based on information obtained by and/or provided to Stantec at that time. There are no assurances regarding the accuracy and completeness of this information received from others.

Conclusions made within this report consist of Stantec’s professional opinion as of the time of the writing of this report and are based solely on the scope of work described in the report, the limited data available, and the results of the work. They are not a certification of the Subject Property’s environmental condition.

Stantec did not obtain historical records that document the property history in 5-year intervals, and this resulted in data gaps. Although this represents data gaps, these data gaps are not considered to impact the EPs ability to identify RECs unless stated as such. Based on the information obtained during the course of this ESA and general knowledge of development at and near the Subject Property, the absence of this information did not affect the ability of the EPs to identify RECs, HRECs, CRECs, or de minimis conditions.

This report has been prepared for the exclusive use of the client identified herein and any use of or reliance on this report by any third party is prohibited, except as may be consented to in writing by Stantec or as required by law. The provision of any such consent is at Stantec’s sole and unfettered discretion and will only be authorized pursuant to the conditions of Stantec’s standard form reliance letter.

Stantec assumes no responsibility for losses, damages, liabilities, or claims, howsoever arising, from third party use of this report.

Project Specific limiting conditions are provided in Section 2.2.

The locations of any utilities, buildings and structures, and property boundaries illustrated in or described within this report, if any, including pole lines, conduits, water mains, sewers and other surface or subsurface utilities and structures, are not guaranteed. Before starting site work, the exact location of all such utilities and structures must be confirmed by the client and the party performing the work, and Stantec assumes no liability resulting from damage to such utilities and structures.

The conclusions are based on the conditions encountered at the Subject Property by Stantec at the time the work was conducted. Accordingly, additional studies and actions may be required.

As the purpose of this report is to identify Subject Property conditions which may pose an environmental risk; the identification of non-environmental risks to structures or people on the Subject Property is beyond the scope of this assessment.

Records Review
May 1, 2025
Project No.: 185806936 4.1

4.0 RECORDS REVIEW
The objective of consulting historical sources of information is to develop the history of the Subject Property and surrounding area and evaluate if past uses may have resulted in RECs. Physical setting records are evaluated to determine if the physical setting may have contributed to adverse environmental conditions in connection with the Subject Property. During the review of historical records, Stantec attempted to identify uses of the Subject Property from the present to the first developed use of the Subject Property. Stantec’s research included the reasonably ascertainable and useful records described in this section.

4.1 PHYSICAL SETTING
A summary of the physical setting of the Subject Property is provided in the table below with additional details in the following subsections:

Topography: According to the United States Geologic Survey (USGS) Corona North topographic map provided in the
Environmental Data Resources Inc. (EDR) Physical Setting Source Addendum (Appendix D), the topographic gradient in the vicinity of the Subject Property is to the south-southeast and the Subject Property is located at approximately 576 feet above mean sea level (ft. amsl).

Soil/Bedrock Data: The United States Department of Agriculture – Natural Resources Conservation Service (USDA-NRCS), Web Soil
Survey identifies the soils beneath the Subject Property as:
• Chino silt loam, with well-drained soil with
moderately coarse textures. A typical soil profile is
comprised of fine grained silty-clay (0-59 inches).

Estimated Depth to Groundwater/
Estimated Direction of Gradient:

Site specific groundwater investigations were not conducted during this ESA; however, according to a 2012 groundwater monitoring report for a site located approximately two miles southeast of the Subject Property, groundwater in the vicinity is approximately 23-28 feet below ground surface (bgs) with a flow direction to the south southeast.

NOTE:

Site-specific groundwater flow direction and depth can only be determined by conducting site-specific testing, which Stantec has not conducted.

4.1.1 Subject Property Topography and Surface Water Flow The Subject Property is located at an elevation of approximately 576 ft amsl. Based on the topography and existing surface conditions, general surface water flow is to the south-southeast. 2337

Records Review
May 1, 2025
Project No.: 185806936 4.2

4.1.2 Regional and Subject Property Geology
The Subject Property is located with the Upper Santa Ana Valley Groundwater Basin, Chino Subbasin (8- 002.01). The Chino Subbasin is bound by the Rialto-Colton Fault to the east; the Jurupa Mountains to the southeast; the Puente Hills and Chino Fault to the south; the San Jose Fault to the northwest; and the San Gabriel Mountains and Cucamonga Fault to the north. Surface water drains south via San Antonio Creek and Cucamonga Creek towards Santa Ana River. Several of the faults create groundwater barriers which in turn generate changes in ground water elevations throughout the subbasin. Water-bearing formations within the subbasin are Holocene and Upper Pleistocene alluvium. The total groundwater storage capacity in the subbasin is approximately 18,300,000 acre-feet (DWR, 2003).

According to California DOC Earthquake Zone Map (Department of Conservation Map Server (ca.gov)), the Subject Property is not located within an Alquist-Priolo (AP) Earthquake Fault Zone boundary. The nearest fault is located approximately four miles to the west of the Subject Property.

4.1.3 Regional and Subject Property Hydrogeology
The Subject Property is located with the Upper Santa Ana Valley Groundwater Basin, Chino Subbasin (8- 002.01). Several faults that lie within the subbasin create groundwater barriers which in turn generate changes in ground water elevations throughout the subbasin. Water-bearing formations within the subbasin are Holocene and Upper Pleistocene alluvium. The total groundwater storage capacity in the subbasin is approximately 18,300,000 acre-feet (DWR, 2003).

4.2 FEDERAL, STATE AND TRIBAL ENVIRONMENTAL RECORDS
A regulatory agency database search report was obtained from EDR, a third-party environmental database search firm. A complete copy of the database search report, including the date the report was prepared, the date the information was last updated, and the definition of databases searched, is provided in Appendix D.

Stantec evaluated the information listed within the database relative to potential impact to the Subject Property, assessing the potential for impacts based in part on the physical setting. As part of this process, inferences have been made regarding the likely groundwater flow direction at or near the Subject Property. As described in 4.1.3, the inferred shallow groundwater flow direction is likely to be to the southeast. Observations about the Subject Property and adjoining properties made during the Subject Property reconnaissance are provided in more detail in Section 5.

4.2.1 Listings for Subject Property
The Subject Property is not listed in the EDR databases. 2338

Project No.: 185806936 4.3

4.2.2 Listings for Adjoining and Nearby Sites with Potential to Impact Subject Property
Stantec assessed data presented in the environmental agency database search report to evaluate the potential for conditions on adjoining and nearby sites to pose a REC, CREC, or HREC for the Subject Property. The evaluation included an opinion of the potential for contamination by hazardous substances or petroleum products to migrate to the Subject Property from an adjoining or nearby site, including by vapor migration or encroachment (i.e., potential for a vapor encroachment condition [VEC]. ASTM E2600- 22 Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions (ASTM, 2022) was used as the basis for a Tier I Vapor Encroachment Screen (VES) for the Subject Property. This included evaluation of release sites within 1/10 mile for Petroleum Hydrocarbon releases, and 1/3 mile for volatile and semi-volatile organic compound (VOC, SVOC), plus other potential vapor phase contaminants (such as mercury).

The site had been used as a dairy operation from approximately 1961 to 2004. The dairy included two residences, milking barn and workshop building, cattle enclosure pens and water troughs. The barn was also used for vehicle maintenance and repairs. A Preliminary Environmental Assessment (PEA) was submitted on April 12, 2017, to the California Department of Toxic Substances Control (DTSC).

The PEA investigation activities included lead from lead]based paints, heavy metals associated with stockpiles suspected to have been stored onsite, total petroleum hydrocarbons (TPH) associated with machinery and/or an underground storage tank (UST) that may have been used at the Site, volatile organic compounds (VOCs) associated with fuels and solvents or septic tanks, organochlorine pesticides (OCPs) associated with past farming and pest control activities, and methane from decay of dairy related organic waste that may pose a threat to human health and the environment. Based on review of the PEA, neither a release of hazardous material nor the presence of a naturally occurring hazardous material, which would pose a threat to public health or the environment under unrestricted land use, was indicated at the Site. Therefore, DTSC concurred with the conclusion of the PEA that further environmental investigation of the Site was not required and approved the PEA. Therefore, this site is not considered a REC to the Subject Property.

The remaining listings in the database search report, including listings of Orphan Sites provided in Appendix D do not constitute a potential REC for the Subject Property.

4.3 LOCAL/REGIONAL ENVIRONMENTAL RECORDS
Stantec checked the following sources to obtain information pertaining to Subject Property use and/or indications of RECs in connection with the Subject Property:

4.4 HISTORICAL RECORDS REVIEW

4.4.1 Land Title Records/Deeds
No environmental liens and/or activity and use limitations were identified in the Preliminary Title Reports provided by First American Title Company dated February 28, 2025. No other land title records, deeds, environmental liens, and activity and use limitation documentation were provided by the User, and public records were not searched by Stantec.

4.4.2 Aerial Photographs
Stantec reviewed historical aerial photographs provided by EDR. The general type of activity on a property and land use changes can often be discerned from the type and layout of structures visible in the photographs. However, specific elements of a facility's operation usually cannot be discerned from aerial photographs alone. The following table summarizes Stantec’s observations of the reviewed historical aerial photographs. Copies of the historical aerial photographs are provided in Appendix E.

4.4.3 City Directories
Stantec retained a third party to research available city directories for the Subject Property and adjoining and nearby properties, in approximately five-year intervals. Copies of the city directory listings are provided in Appendix E. The Subject Property is listed in the city directory between 1992 and 2020 as Dean Visscher / Visscher Livestock Transportation / Cow Truck Inc. Adjoining properties and properties within the vicinity include primarily residential listings.

4.4.4 Historical Fire Insurance Maps
Fire insurance maps were developed for use by insurance companies to depict facilities, properties, and their uses for many locations throughout the United States. These maps provide information on the history of prior land use and are useful in assessing whether there may be potential environmental contamination on or near the Subject Property. These maps, which have been periodically updated since the late 19th century, often provide valuable insight into historical Subject Property and adjoining and nearby property uses.

Stantec requested fire insurance maps from EDR; however, no coverage exists for the Subject Property.

The Sanborn® Map Search Report indicating “No Coverage” is presented in Appendix E.

4.4.5 Historical Topographic Maps
Stantec reviewed historical USGS 7.5-minute Topographic Maps of the Corona North and Corona and Vicinity, California Quadrangles (scales 1:24,000 and 1:31,680), the historical USGS 15-minute Topographic Maps of the Corona, California Quadrangles (scale 1:50,000), and the historical USGS 30- minute Topographic Maps of the Corona, California (scale 1:125,000) to help identify past Subject Property and adjoining and nearby property usage and areas of potential environmental concern. Copies of the historical maps are provided in Appendix E.

PHASE I ENVIRONMENTAL SITE ASSESSMENT
Evaluation
May 1, 2025
Project No.: 185806936 6.1

6.0 EVALUATION
This section provides a summary overview of or Findings, Opinions, and Conclusions.

6.1 FINDINGS AND OPINIONS
Information gathered from interviews, reviews of existing data, and an inspection was evaluated to determine if RECs are present in connection with the Subject Property. Based on this information, Stantec made the following findings and developed the following opinions. • Based on review of historical sources including aerial photographs and city directory listings, the Subject Property was formerly utilized for livestock holding and a storage area of the trucks and trailers used in the transportation of livestock. During the site reconnaissance, a former cattle pen was observed in the southern portion of the Subject Property along Walters Avenue. No evidence of dairy operations or agricultural use was observed on the Subject Property. • An environmental records search was performed and identified sites within their respective ASTM E1527-21 search radii of the Subject Property that may represent RECs, CRECs, HRECs, or de minimis conditions.

Based on one or more of the following reasons: distance from the Subject Property, position of sites with respect to assumed groundwater flow direction, the type of native soils, and regulatory status, none of the sites identified in the environmental records search report are expected to impact soil or groundwater quality at the Subject Property. The environmental records search identified no RECs, CRECs, HRECs or de minimis conditions at or near the Subject Property. • During the site reconnaissance, an irrigation well was observed in the northern portion of the Subject Property. The presence of an irrigation well is not considered an environmental concern to the Subject Property; however, if the well is not going to be used in the future it should be decommissioned in accordance with applicable regulatory requirements before grading activities occur.
• Debris piles with various household debris, used tires, and building demolition waste were also observed in the center of the Subject Property. The discarded building materials should be tested for the presence of asbestos-containing materials (ACMs) before off-site disposal in accordance with applicable federal and local regulations.

6.2 DATA GAPS
The federal AAI final rule [40 CFR 312.10(a)] and ASTM E1527-21 identify a “data gap” as the lack or inability to obtain information required by the standards and practices of the rule despite good faith efforts by the EP or the User.

Any data gaps resulting from the Phase I ESA described in this report are listed and discussed below. 2349

Data Gaps from Interviews: Due to the sensitive nature of the transaction no on-site interview was conducted. Given the historical documents, the lack of an on-site interview is not considered to impact the findings of this report.

Other Data Gaps: None.

6.3 CONCLUSIONS
We have performed a Phase I ESA in conformance with the scope and limitations of ASTM Practice E1527-21 of the Subject Property. Any exceptions to, or deletions from, this practice are described Section 2.3 of this report. This assessment has revealed no recognized environmental conditions (RECs), Controlled RECs (CRECs), or significant data gaps in connection with the Subject Property. No further investigation appears to be warranted at this time.

PHASE I ENVIRONMENTAL SITE ASSESSMENT
Non-Scope Considerations
May 1, 2025
Project No.: 185806936 7.1

7.0 NON-SCOPE CONSIDERATIONS
The following ASTM E1527-13 non-scope services were performed as part of this Phase I ESA:

7.1 LEAD-BASED PAINT
Concern for LBP is primarily related to residential structures. The EPA’s Final Rule on Disclosure of LeadBased Paint in Housing (40 CFR Part 745) defines LBP as paint or other surface coatings that contain lead equal to or in excess of 1.0 milligram per square centimeter or 0.5 percent by weight.

The risk of lead toxicity in LBP varies based upon the condition of the paint and the year of its application.

The U.S. Department of Housing and Urban Development (HUD) has identified the following risk factors:
• The age of the dwelling as follows:
− Maximum risk is from paint applied before 1950.
− There is severe risk from paint applied before 1960.
− There is moderate risk from deteriorated paint applied before 1970. − There is slight risk from the paint that is intact but applied before 1977. • The condition of the painted surfaces.
• The presence of children and certain types of households in the building. • Previously reported cases of lead poisoning in the building or area.

Given there are no structures present LBP is not considered an environmental concern.

7.2 ASBESTOS
Asbestos can be found in many applications, including sprayed-on or blanket-type insulation, pipe wraps, mastics, floor and ceiling tiles, wallboard, mortar, roofing materials, and a variety of other materials commonly used in construction. The greatest asbestos-related human health risks are associated with friable asbestos, which is ACM that can be reduced to powder by hand pressure. Friable asbestos can become airborne and inhaled, which has been associated with specific types of respiratory disease. The manufacturing and use of asbestos in most building products was curtailed during the late 1970s.

The building material debris pile should be tested for asbestos before it is disposed of off-site.

7.3 RADON
Radon is a colorless, tasteless radioactive gas with an EPA-specified action level of 4.0 PicoCuries per liter of air (pCi/L) for residential properties. Radon gas has a very short half-life of 3.8 days. The health risk potential of radon is primarily associated with its rate of accumulation within confined areas near or in the ground, such as basements, where vapors can readily transfer to indoor air from the ground through foundation cracks or other pathways. Large, adequately ventilated rooms generally present limited risk for 2351

PHASE I ENVIRONMENTAL SITE ASSESSMENT
Non-Scope Considerations
May 1, 2025
Project No.: 185806936 7.2
radon exposure. The radon concentrations in buildings and homes depend on many factors, including soil types, temperature, barometric pressure, and building construction (EPA, 1993).

Stantec reviewed regional data published by the EPA on average indoor radon concentrations in the vicinity of the Property (http://www.epa.gov/radon/zonemap.html).

EPA Radon Zones (w/Average Measured Indoor Radon concentrations) Zone 1 – High
(>4.0 pCi/L)
Zone 2 – Moderate
(2 to 4 pCi/L)
Zone 3 – Low
(<2 pCi/L)
X
Normally occupied sub grade areas present? (i.e., basement apartments, offices, stores, etc.) No subgrade areas currently present at the Property.

The Subject Property is located in Zone 2 and is considered to have a moderate potential for radon. To determine Subject Property-specific radon levels, a radon survey would have to be conducted. However, because the Subject Property does not have any occupied subgrade areas and is planned for redevelopment, further investigation of indoor radon issues does not appear to be warranted.

7.4 FLOOD ZONES
According to the Physical Setting summary portion of the EDR report, the eastern border (adjoining the Santa Ana River) of the Subject Property is located within a 0.2% Annual Chance Flood Hazard Zone. 2352

Chemicals & Polymers
Two Former Chemical Plants, Environmental Site
Assessments and Remediation, Vernon, California
Mr. Emerson was part of the team for conducting
Phase I and Phase II Environmental Site
Assessments (ESA) and developing remedial
action plans for two former chemical plant sites
with 80-year industrial histories. Phase I ESAs
used historical files, maps, aerial photographs,
available documents, and data from public
agencies and historical directories for identifying
recognized environmental concerns. Extensive
Phase II ESA survey activities aided in identifying
below-grade structures such as vaults/USTs, as
well as assessing the extent of influence and
nature of the contamination. These investigations
confirmed the presence of heavy metals,
petroleum hydrocarbons, volatile organic
compounds, polychlorinated biphenyls, radioactive
materials, semi-volatile organic compounds, and
polycyclic aromatic compounds in the soils for
these sites. Specific areas of concern included
former settling ponds, a bone yard, maintenance
areas, transformer and substations, wastewater
treatment facilities, and above-ground storage
tank farms. A conceptual mode was developed for
use in a health risk assessment and developed
risk-based corrective actions to address potential
health and environmental concerns. He assisted
with the development and implementation of a
remedial action plan, combined administrative
controls, engineering controls, and active
remediation; this resulted in the cost-effective
return of one site to active use, and is reducing
health risks to occupants and the public at the
second site.

CONFIDENTIAL: Aerospace Adhesives and
Coatings Plant, Glendale, California
Mr. Emerson was part of the team that conducted
feasibility studies to evaluate remedial alternatives

and groundwater. Feasibility studies included
groundwater pump testing, benchscale column
testing to evaluate in situ alternatives for reducing
CrVI to the less mobile CrIII valence state, soil
vapor extraction, capping, and excavation. Field
pilot studies were performed to evaluate the
efficiency of various CrVI reductants including the
use of ferrous sulfate, calcium polysulfide,
emulsified oil, and fructose. Extensive multi-depth
soil vapor testing was conducted to evaluate the
distribution of VOCs in the subsurface and to
support vapor intrusion risk assessment.

Feasibility studies were completed in 2008.

Remedial actions are expected to be completed in
2011.

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

STANDARD ENVIRONMENTAL RECORDS
Lists of Federal CERCLA sites with NFRAP
SEMS-ARCHIVE: SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

A review of the SEMS-ARCHIVE list, as provided by EDR, and dated 12/19/2024 has revealed that there 2402

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites.

A review of the ENVIROSTOR list, as provided by EDR, and dated 01/21/2025 has revealed that there are 4 ENVIROSTOR sites within approximately 1 mile of the target property.

SEMS: Superfund Enterprise Management System
SEMS (Superfund Enterprise Management System) tracks hazardous waste sites, potentially hazardous waste sites, and remedial activities performed in support of EPA’s Superfund Program across the United States. The list was formerly know as CERCLIS, renamed to SEMS by the EPA in 2015. The list contains data on potentially hazardous waste sites that have been reported to the USEPA by states, municipalities, private companies and private persons, pursuant to Section 103 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

This dataset also contains sites which are either proposed to or on the National Priorities List (NPL) and the sites which are in the screening and assessment phase for possible inclusion on the NPL.

SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

US BROWNFIELDS: A Listing of Brownfields Sites
Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these properties takes development pressures off of undeveloped, open land, and both improves and protects the environment.

Assessment, Cleanup and Redevelopment Exchange System (ACRES) stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on Targeted Brownfields Assessments performed by EPA Regions. A listing of ACRES Brownfield sites is obtained from Cleanups in My Community. Cleanups in My Community provides information on Brownfields properties for which information is reported back to EPA, as well as areas served by Brownfields grant programs.

The DTSC Hazardous Waste Management Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land use restriction at the local county recorder’s office. The land use restrictions on this list were required by the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners.

EPA WATCH LIST: EPA Watch List
EPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcement matters relating to facilities with alleged violations identified as either significant or high priority. Being on the Watch List does not mean that the facility has actually violated the law only that an investigation by EPA or a state or local environmental agency has led those organizations to allege that an unproven violation has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

The EPA has set ambitious goals for the RCRA Corrective Action program by creating the 2020 Corrective Action Universe. This RCRA cleanup baseline includes facilities expected to need corrective action. The 2020 universe contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.

Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

RMP: Risk Management Plans
When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance for chemical accident prevention at facilities using extremely hazardous substances. The Risk Management Program Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects of an accidental release, an accident history of the last five years, and an evaluation of worst-case and alternative accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee training measures; and Emergency response program that spells out emergency health care, employee training measures and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

PFAS NPDES: Clean Water Act Discharge Monitoring Information Any discharger of pollutants to waters of the United States from a point source must have a National Pollutant Discharge Elimination System (NPDES) permit. The process for obtaining limits involves the regulated entity (permittee) disclosing releases in a NPDES permit application and the permitting authority (typically the state but sometimes EPA) deciding whether to require monitoring or monitoring with limits. Caveats and Limitations:

Less than half of states have required PFAS monitoring for at least one of their permittees and fewer states have established PFAS effluent limits for permittees. New rulemakings have been initiated that may increase the number of facilities monitoring for PFAS in the future.

To date, these military specification fire-fighting foams are fluorinated and have been historically used for training and extinguishing. The 2018 FAA Reauthorization Act has a provision stating that no later than October 2021, FAA shall not require the use of fluorinated AFFF. This provision does not prohibit the use of fluorinated AFFF at Part 139 civilian airports; it only prohibits FAA from mandating its use. The Federal Aviation Administration?s document AC 150/5210-6D - Aircraft Fire Extinguishing Agents provides guidance on Aircraft Fire Extinguishing Agents, which includes Aqueous Film Forming Foam (AFFF).

EDR HIGH RISK HISTORICAL RECORDS
EDR Exclusive Records
EDR MGP: EDR Proprietary Manufactured Gas Plants
The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.
