*B6. Construction History:

The concrete-lined drainage channel was constructed between 1962 and 1965, likely in conjunction with the construction of Interstate 10 to address the existing surface runoff drainage problems in the area. By 1972, the drainage channel was extended further east, and by 2010-2012, the channel was extended to the northeast to connect it to the drainage infrastructure of the Singleton Heights residential subdivision. *B7.

*B10. Significance: Theme Area
Period of Significance Property Type Applicable Criteria: None Criterion A/1: The concrete-lined drainage channel does not appear to be directly associated with any historically significant events, trends, patterns, or themes at the local, state, or federal level. Therefore, the concrete-lined drainage channel is not historically significant under Criterion A/1.

Criterion B/2: Research has not revealed any significant association between the drainage channel and any historically significant persons at the national, state or local level. Therefore, the concrete-lined drainage channel is not historically significant under Criterion B/2.

Criterion C/3: The design, materials and method of construction of the channel are not unique and are typical of similar structures found all over the state. The drainage channel is not a significant design feature or element of the freeway infrastructure. Therefore, the concrete-lined drainage channel is not historically significant under Criterion C/3.

Criterion D/4: This criterion is most relevant for archaeological sites, but it can be applied to historic built-environment resources if further study has the potential to yield information that cannot be obtained from other sources. However, further study of the concrete-lined drainage channel would not add any new information to the historic record or our understanding of the area or the development of Interstate 10 or Singleton Road. Therefore, the concrete-lined drainage channel is not historically significant under Criterion D/4.

DRAFT PALEONTOLOGICAL RESOURCES ASSESSMENT FOR THE CALIMESA BOULEVARD

REALIGNMENT PROJECT, RIVERSIDE COUNTY, CALIFORNIA
vii
Stantec Project Number 235100543
Executive Summary
Stantec Consulting Services Inc. (Stantec) conducted a paleontological resources assessment on behalf of HELIX Environmental Planning, Inc. for the Calimesa Boulevard Realignment Project (the Project) on portions of approximately 13 acres of land located at the intersection of Calimesa Boulevard and Singleton Road in the City of Calimesa (the City), Riverside County, California. This paleontological study was conducted in support of the proposed realignment and widening of Calimesa Boulevard and widening of Singleton Road.

The proposed Project is subject to compliance with the California Environmental Quality Act (CEQA) and City requirements regarding the Project's potential impacts on paleontological resources. The lead agency for this Project is the City of Calimesa. As part of CEQA compliance, a paleontological resources assessment was conducted to assess potential impacts of the proposed Project on paleontological resources.

This paleontological resources investigation consisted of an analysis of existing data including a museum records search from the Natural History Museum of Los Angeles County and a review of the most recent geologic mapping and relevant scientific literature. This research was used to assign paleontological potential rankings of the Society of Vertebrate Paleontology (2010) to the geologic units present in the Project area, either at the surface or in the subsurface. Following this, Project plans were reviewed to identify any potential impacts to paleontological resources and develop appropriate mitigation recommendations to reduce potential impacts to less than significant.

The results of the analysis of existing data conducted indicate that five geologic units are likely present in the Project area: very young wash deposits and young axial valley deposits, which are assessed as having low paleontological potential; and very old alluvial fan deposits, sedimentary deposits of Live Oak Canyon, and the San Timoteo Formation, which are assessed as having high paleontological potential. In order to avoid impacts to paleontological resources and satisfy CEQA and City requirements, Stantec recommends a qualified paleontologist meeting professional standards as defined by the Society of Vertebrate Paleontology (2010) or Murphey et al. (2019) be retained to oversee all aspects of paleontological mitigation as the designated Project Paleontologist. In order to avoid impacts to paleontological resources, Stantec recommends the following mitigation activities for the Project:
• The Project Paleontologist should develop and oversee the implementation of a Paleontological Monitoring and Mitigation Plan tailored to the Project plans (when they are available) that provides for paleontological monitoring of earthwork and ground disturbing activities into undisturbed geologic units with high paleontological potential, whether at the surface or in the subsurface, to be conducted by a paleontological monitor meeting industry standards (Murphey et al. 2019). Monitoring recommendations are as follows:

DRAFT PALEONTOLOGICAL RESOURCES ASSESSMENT FOR THE CALIMESA BOULEVARD

REALIGNMENT PROJECT, RIVERSIDE COUNTY, CALIFORNIA

Stantec Project Number 235100543
o Paleontological spot checks will be conducted by a qualified paleontological monitor for initial ground disturbance between 3 feet and 5 feet in depth in portions of the Project area mapped as very young wash deposits (abbreviated as Qvywm and Qvyw2 by Matti et al. [2015]) and young axial valley deposits (abbreviated as Qya5 by Matti et al. [2015]).

Should sediments with high paleontological potential be identified during spot checks, full time monitoring will be implemented.
o Full time paleontological monitoring will be implemented once excavations reach 5 feet in depth in areas mapped as very young wash deposits (abbreviated as Qvywm and Qvyw2 by Matti et al. [2015]) and young axial valley deposits (abbreviated as Qya5 by Matti et al. [2015]).
o Full time paleontological monitoring will be conducted for all ground disturbance into previously undisturbed areas mapped as very old alluvial fan deposits (abbreviated as Qvof3 by Matti et al. [2015]).
o The Project Paleontologist may reduce the frequency of monitoring or spot checks should subsurface conditions indicate low paleontological potential. • The Project Paleontologist should develop a Worker’s Environmental Awareness Program training that communicates requirements and procedures for the inadvertent discovery of paleontological resources during construction, to be delivered by the paleontological monitor to the construction crew prior to the onset of ground disturbance. • In the event that paleontological resources are encountered during construction activities, all work must stop in the immediate vicinity of the finds while the paleontological monitor documents the find. The Project Paleontologist shall assess the find. Should the Project Paleontologist assess the find as significant, the find shall be collected and curated in an accredited repository along with all necessary associated data and curation fees.

Based on the findings in this study and the implementation of the above mitigation recommendations, the proposed Project should not cause an adverse impact to paleontological resources. Therefore, no additional paleontological resources studies are recommended or required at this time. Changes to the Project plans or Project area from those assessed in this study will require additional assessment for impacts to paleontological resources.

Introduction
1 1.0 INTRODUCTION
Stantec Consulting Services Inc. (Stantec) conducted a paleontological resources assessment on behalf of HELIX Environmental Planning, Inc., for the Calimesa Boulevard Realignment Project (the Project) on portions of approximately 13 acres of land located at the intersection of Calimesa Boulevard and Singleton Road, in the City of Calimesa, Riverside County, California. This paleontological study was conducted in support of the proposed Calimesa Boulevard Realignment Project.

The proposed Project is subject to compliance with the California Environmental Quality Act (CEQA) and City of Calimesa (City) requirements regarding the Project's potential impacts on paleontological resources. The lead agency for the Project is the City. As part of CEQA compliance, a paleontological resources assessment was conducted to assess potential impacts of the proposed Project on paleontological resources.

1.1 PROJECT DESCRIPTION
The Project proposes to realign 0.6 miles of Calimesa Boulevard 300 feet to the east of its current location, placing it 400 feet from the Interstate 10 westbound ramps, and widen it by 75 feet in order to meet the recommendations of the City’s General Plan. Singleton Road would stay in its original alignment and would be widened by 75 feet for a length of 700 feet. This includes modifications to portions of Singleton Road that would be impacted by the realignment of Calimesa Boulevard. Project Location The proposed Project is located at the intersection of Calimesa Boulevard and Singleton Road, within the City, in Riverside County, California (Figure 1). Specifically, the Project area is located within Section 24, Township 2 South, Range 2 West, as depicted on the El Casco (2003), California United States Geologic Survey 7.5-minute series topographic quadrangle (Figure 2).

1.2 PALEONTOLOGICAL RESOURCES
Fossils are any evidence of ancient life. This includes the remains of the body of an organism, such as bones, skin impressions, shell, or leaves, as well as traces of an organism’s activity, such as footprints or burrows, called trace fossils. In addition to the fossils themselves, geologic context is an important component of paleontological resources, and includes the stratigraphic placement of the fossil as well as the lithology of the rock or sediment in order to assess paleoecologic setting, depositional environment, and taphonomy. Fossils are protected by federal, state, and local regulations as nonrenewable natural resources.

Introduction
4 While CEQA does not define a significance threshold for paleontological resources, the standards of the Society of Vertebrate Paleontology (SVP) are often used in the absence of a legal definition of significance. The SVP defines significant paleontological resources as:
identifiable vertebrate fossils, large or small, uncommon invertebrate, plant, and trace fossils, and other data that provide taphonomic, taxonomic, phylogenetic, paleoecologic, stratigraphic, and/or biochronologic information. Paleontological resources are considered to be older than recorded human history and/or older than middle Holocene (i. e., older than about 5,000 radiocarbon years). [SVP 2010: 11].

Furthermore, the Paleontological Resources Preservation Act (PRPA) defines paleontological resources as:

Any fossilized remains, traces, or imprints of organisms, preserved in or on the earth’s crust, that are of paleontological interest and that provide information about the history of life on earth, except that the term does not include— (A) any materials associated with an archaeological resource (as defined in section 3(1) of the Archaeological Resources Protection Act of 1979 (16 U.S.C. 470bb(1)); or (B) any cultural item (as defined in section 2 of the Native American Graves Protection and Repatriation Act (25 U.S.C. 3001)). [PRPA Sec. 6301] Using these definitions, the concept of scientific importance, or significance, is included in the definition of paleontological resources; thus, not all fossils are considered to be paleontological resources under the SVP and PRPA.

It should be noted that the threshold for significance varies with a variety of factors, including geologic unit, geographic area, and the current state of scientific research, and may also vary between different agencies (Murphey et al. 2019). Numerous paleontological studies have developed criteria for the assessment of significance for fossil discoveries (e.g., Eisentraut and Cooper 2002, Murphey et al. 2019, Murphey and Daitch 2007, Scott and Springer 2003). In general, these studies assess fossils as significant if one or more of the following criteria apply:
• The fossils provide information on the evolutionary relationships and developmental trends among organisms, living or extinct.
• The fossils provide data useful in determining the age(s) of the rock unit or sedimentary stratum, including data important in determining the depositional history of the region and the timing of geologic events, through biochronology or biostratigraphy and the correlation with isotopic dating.
• The fossils provide ecological data, such as the development of biological communities, the interaction between paleobotanical and paleozoological biotas, or the biogeography of lineages.
• The fossils demonstrate unusual or spectacular circumstances in the history of life.

Regulatory Framework
5 • The fossils provide information on the preservational pathways of paleontological resources, including taphonomy, diagenesis, or preservational biases in the fossil record. • The fossils are in short supply and/or in danger of being depleted or destroyed by the elements, vandalism, or commercial exploitation, and are not found in other geographic locations. • The fossils inform our understanding of anthropogenic affects to global environments or climate.

A geologic unit known to contain significant paleontological resources is considered sensitive to adverse impacts if there is a high probability that earth-moving or ground-disturbing activities in that rock unit will either disturb or destroy fossil remains directly or indirectly. This definition of sensitivity differs fundamentally from the definition for archaeological resources as follows:

It is extremely important to distinguish between archaeological and paleontological (fossil) resource sites when defining the sensitivity of rock units. The boundaries of archaeological sites define the areal extent of the resource. Paleontological sites, however, indicate that the containing sedimentary rock unit or formation is fossiliferous. The limits of the entire rock formation, both areal and stratigraphic, therefore define the scope of the paleontological potential in each case. [SVP 2010: 2].

Many archaeological sites contain features that are visually detectable on the surface. In contrast, fossils are often contained within surficial sediments or bedrock and are therefore not observable or detectable unless exposed by erosion or human activity.

In summary, in the absence of observable paleontological resources on the surface, paleontologists must assess the potential of geologic units as a whole to yield paleontological resources based on their known potential to produce significant fossils elsewhere. Monitoring by experienced paleontologists greatly increases the probability that fossils will be discovered during ground-disturbing activities and that, if these remains are significant, successful mitigation and salvage efforts may be undertaken to prevent adverse impacts to these resources.

2.0 REGULATORY FRAMEWORK
This investigation was conducted to meet relevant state and local requirements of the Project regarding paleontological resources on the lands proposed for development. California and the City have enacted multiple laws and regulations that provide for the protection of paleontological resources.

2.1 STATE OF CALIFORNIA

2.1.1 California Environmental Quality Act
CEQA (Public Resources Code Sections 21000 et seq) requires that before approving most discretionary projects, the Lead Agency must identify and examine any significant adverse environmental effects that

REALIGNMENT PROJECT, RIVERSIDE COUNTY, CALIFORNIA
Regulatory Framework
6 may result from activities associated with such projects. As updated in 2016, CEQA separates the consideration of paleontological resources from cultural resources (Public Resources Code Section 21083.09). The Appendix G checklist (Title 14, Division 6, Chapter 3, California Code of Regulations 15000 et seq.) requires an answer to the question, “Will the proposed project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?” Under these requirements, Stantec has conducted a paleontological resources assessment to determine impacts of the proposed project on paleontological resources within the Project area.

2.1.2 Public Resources Code
The California Public Resources Code (Chapter 1.7, Sections 5097 and 30244) includes additional statelevel requirements for the assessment and management of paleontological resources. These statutes require reasonable mitigation of adverse impacts to paleontological resources resulting from development on state lands, define the removal of paleontological sites or features from state lands as a misdemeanor, and prohibit the removal of any paleontological site or feature from state land without permission of the applicable jurisdictional agency.

2.2 LOCAL REGULATIONS

2.2.1 City of Calimesa General Plan
The City’s (2014) General Plan recognizes the importance of paleontological resources. Chapter 2, Land Use, specifies that paleontological resources assessments must be conducted prior to approval of any development and identifies paleontological sensitivity as one of several justifications for Open Space designation, while, Chapter 6, Resource Management, identifies the preservation of paleontological resources as a goal. Goal RM-4 codifies the City’s intent to, “Preserve the city's historical, cultural, archaeological, paleontological, and architectural resources” (City of Calimesa 2014). This goal includes one policy with two action items designed to protect paleontological resources:
• ACTION ITEM RM-16.3: Review all proposed development for the possibility of cultural/archaeological/paleontological sensitivity. When existing information indicates that a site proposed for development may contain paleontological resources, a report stating the extent and potential significance of the resources that may exist within the proposed development shall be prepared and include mitigation measures as appropriate. • ACTION ITEM RM-16.4: The City will work with the Native American community and others to adopt an appropriate process and procedure for the monitoring of excavation in cultural and paleontological sensitive areas and adopt a process for ensuring the appropriate curation of any cultural or paleontological resources discovered.

Professional Standards
7 3.0 PROFESSIONAL STANDARDS
The SVP (2010), the Bureau of Land Management (2016), and a number of scientific studies (Eisentraut and Cooper 2002; Murphey et al. 2019; Scott and Springer 2003) have developed guidelines for professional qualifications, conducting paleontological assessments, and developing mitigation measures for the protection of paleontological resources. These guidelines are broadly similar, and include the use of museum records searches, scientific literature reviews, and, in some cases, field surveys to assess the potential of an area to preserve paleontological resources. Should that potential be high, accepted mitigation measures include paleontological monitoring, data recordation of all fossils encountered, collection and curation of significant fossils and associated data, and in some cases screening of sediment for microfossils.

This study has been conducted in accordance with these guidelines and the recommendations provided herein meet these standards.

4.0 GEOLOGIC SETTING
The Project area is located at the northeastern end of the Peninsular Ranges geomorphic province. The Peninsular Ranges formed when a volcanic island arc collided with the west coast of North America and was accreted onto the margin of the continent, resulting in the expansion of the continent westward. The Peninsular Ranges are part of a larger subduction zone that extends all along western North America, with this particular geomorphic province extending from the Los Angeles Basin in the north to Baja in the south, and extending to Santa Catalina, Santa Barbara, San Nicolas, and San Clemente Islands on the west and the Colorado Desert on the east (Norris and Webb 1990). The core of the Peninsular Ranges formed as the core of a magmatic arc in the Mesozoic that resulted from active subduction along the Pacific Plate boundary (Harden 2004).

Two main batholiths of plutonic rock form the core of the Peninsular Ranges. The western batholith, was emplaced first and is 140 – 105 million years old (Ma) and consists of mafic plutonic rocks, while the eastern batholith is 99 – 92 Ma and consist of silica-rich granodiorites and tonalities (Kimbrough et al. 2001). These plutonic rocks intruded into the older rocks of a Paleozoic carbonate platform, heavily metamorphosing them (Harden 2004). There was volcanic activity associated with the subduction zone as well, with the Santiago Peak Volcanics deposited from 130 – 120 Ma as primarily andesitic and silicic flows, that were then metamorphosed by the ongoing batholith emplacement (Fife et al. 1967). Later in the Cretaceous, marine sedimentary rocks accumulated over the plutons and volcanic rocks, deposited as turbidity currents in what was an ocean at the time (Kimbrough et al. 2001). These rocks are in turn overlain by more recent sedimentary deposits leading up to the present day, that have been heavily uplifted and faulted by tectonic activity throughout the Cenozoic. These deposits were marine through the Eocene and then shifted to terrestrial volcanic and sedimentary strata by the Oligocene and lower Miocene (Powell 1993).

Methodology
8 Locally, the Project area is at the western end of the San Gorgonio Pass. The San Gorgonio Pass marks the northern boundary of the Peninsular Ranges geomorphic province and is an approximately 15-milelong, east-west-trending, tectonically complex valley representing a dropped block between the San Bernardino Mountains to the north and the San Jacinto Mountains to the south, controlled by the underlying left-stepping restraining bend in the San Andreas Fault, the largest discontinuity along the entire length of the fault (Dair and Cooke 2009; Yule 2009). Delineated on its north by the Banning Fault, the sedimentary rocks of the San Gorgonio Pass range from upper Miocene to Quaternary in age and are mostly the result of alluvial fan and floodplain deposition (Allen 1957). San Gorgonio Pass slopes downward to the east, opening into the alluvial-filled Coachella Valley. On the west, it transitions into predominantly older alluvial soils of the Beaumont Plain.

5.0 METHODOLOGY
The paleontological resources assessment reported herein consisted of a desktop analysis incorporating a museum records search from the Natural History Museum of Los Angeles County (LACM) and review of the scientific literature and geologic mapping. To assess if paleontological resources are likely to be encountered in any given area, the paleontological potential of the geologic units present in the area is assessed. Paleontological potential of a geologic unit consists of both (a) the potential for yielding abundant vertebrate fossils or for yielding significant fossils, large or small, vertebrate, invertebrate, plant, or trace fossils and (b) the importance of recovered evidence for new and significant taxonomic, phylogenetic, paleoecologic, taphonomic, biochronologic, or stratigraphic data (SVP 2010). Unlike archaeological resources that often have a limited aerial extent, paleontological resources may occur throughout a geologic unit, and so paleontological potential is assessed for the unit as a whole.

The paleontological assessment presented here was conducted by Stantec Principal Paleontologist Alyssa Bell, Ph.D. Geographical Information System (GIS) maps and figures were drafted by GIS Technician Grace Montague, B.S. This report was authored by Alyssa Bell and Ben Kerridge, M.A. and peer reviewed by Senior Principal Cara Corsetti, M.S. Business Center Practice Leader Geraldine Aron, M.S. served as the Stantec Project Manager, coordinated all work, and provided quality assurance and control of this report.

Provided below is the methodology used during the current study to assess the potential of the Project to impact paleontological resources.

5.1 RECORDS SEARCH
A records search of the Project area and vicinity was requested from the LACM on December 1, 2022, with the results received on December 11, 2022. The search returned the closest known paleontological localities of the LACM to the Project area from geologic units that are present at the Project area, either at the surface or in the subsurface.

Methodology
9 5.2 SCIENTIFIC LITERATURE REVIEW
In order to assess the paleontological potential of the Project area, the most recent geologic mapping was consulted to identify all geologic units present at the surface or likely present in the subsurface. The scientific literature was then consulted to determine the history of each of these units for preserving fossil resources.

5.3 PALEONTOLOGICAL RESOURCES ASSESSMENT
The results of the desktop analysis were used to assign the paleontological potential rankings of the SVP (2010) to the geologic units likely present in the Project area. These rankings are designed to inform the development of appropriate mitigation measures for the protection of paleontological resources and are widely accepted as industry standards in paleontological mitigation (Murphey et al. 2019; Scott and Springer 2003). These rankings are as follows:

High Potential. Rock units from which vertebrate or significant invertebrate, plant, or trace fossils have been recovered are considered to have a high potential for containing additional significant paleontological resources. Rock units classified as having high potential for producing paleontological resources include, but are not limited to, sedimentary formations that are temporally or lithologically suitable for the preservation of fossils (e. g., middle Holocene and older, fine-grained fluvial sandstones, argillaceous and carbonate-rich paleosols, cross-bedded point bar sandstones, fine-grained marine sandstones, etc.), some volcaniclastic formations (e. g., ashes or tephras), and some low-grade metamorphic rocks.

Undetermined Potential. Rock units for which little information is available in the literature or museum records concerning their paleontological content, geologic age, and depositional environment are considered to have undetermined potential. Further study and field work is necessary to determine if these rock units have high or low potential to contain significant paleontological resources.

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 (e. g., basalt flows or Recent colluvium) have low paleontological potential.

No Potential. Some rock units have no potential to contain significant paleontological resources, for instance high-grade metamorphic rocks (such as gneisses and schists) and plutonic igneous rocks (such as granites and diorites).

Following the assessment of paleontological potential, an impacts assessment was conducted comparing planned Project activities in terms of locations, depths, and ground disturbance methods with mapped geologic units. Where potential adverse impacts from Project activities were identified, mitigation recommendations were developed to reduce those impacts to less than significant.

REALIGNMENT PROJECT, RIVERSIDE COUNTY, CALIFORNIA
Methodology
10 5.4 PALEONTOLOGICAL IMPACTS ASSESSMENT
Impacts to paleontological resources can be classified as direct, indirect, or cumulative. Impacts can also be considered as adverse impacts or as positive impacts. Direct adverse impacts on paleontological resources are the result of damage or destruction of these nonrenewable resources by surface disturbing actions including construction excavations. Therefore, in areas that contain paleontologically sensitive geologic units, ground disturbance has the potential to adversely impact paleontological resources, by damaging or destroying them and rendering them permanently unavailable to science and society.

Positive direct impacts, however, may result when paleontological resources are identified during construction and the appropriately documented and salvaged, thus ensuring the specimens are protected for future study and education.

Indirect impacts typically include those effects which result from the continuing implementation of management decisions and resulting activities, including normal ongoing operations of facilities constructed within a given project area. They also occur as the result of the construction of new roads and trails in areas that were previously less accessible. This increases public access and therefore increases the likelihood of the loss of paleontological resources through vandalism and unlawful collecting, thus constituting an adverse indirect impact. Human activities that increase erosion also cause indirect impacts to surface and subsurface fossils as the result of exposure, transport, weathering, and reburial.

Cumulative adverse impacts can result from incrementally minor but collectively significant actions taking place over time. The incremental loss of paleontological resources over time from construction-related surface disturbance or vandalism and unlawful collection would represent a significant cumulative adverse impact, because it would result in the destruction of non-renewable paleontological resources and the associated irretrievable loss of scientific information.

Detailed Project plans in the form of the various types and depths of ground disturbance, and the locations of those disturbances within the overall Project area were not available at the time of this assessment. Therefore, this assessment addresses broad potential impacts of ground disturbance in general. This assessment includes the possibility of subsurface geologic units having a different paleontological potential than surficial units. For example, younger surficial sediments (alluvium, lacustrine, eolian, etc.) have low potential to preserve paleontological resources due to their age; yet sediments increase in age with depth and so these surficial deposits often overly older units that have high paleontological potential. In areas with this underlying geologic setting surficial work may be of low risk for impacting paleontological resources while activities that require excavations below the depth of the surficial deposits would be at greater risk of impacting paleontological resources. For this reason, the impact assessment takes into consideration both the surface and subsurface geology.

6.1 PROJECT AREA GEOLOGY AND PALEONTOLOGY
Geologic mapping by Matti et al. (2015) indicates the surface of the Project area consists of very young wash deposits, young axial valley deposits, and very old alluvial fan deposits, with the sedimentary deposits of Live Oak Canyon and the San Timoteo Formation likely present in the subsurface (Figure 3).

These geologic units range in age from the Recent to the Pliocene and are described below, including the results of the museum records search (Table 1) and Stantec’s assessment of the paleontological potential for each unit (Table 2).

Very young wash deposits (abbreviated as Qvywm and Qvyw2 by Matti et al. [2015]). Very young wash deposits are found along much of the Singleton Road realignment portion of the Project area as well as a small portion of the southern segment of the portion of Calimesa Boulevard slated for widening (Figure 3).

These sediments consist of recently transported, very slightly to slightly consolidated sand and gravel in active channels (abbreviated as Qvywm by Matti et al. [2015]) as well as in slightly elevated terraces along the margins of San Timoteo Creek (abbreviated as Qvyw2 by Matti et al. [2015]) (Matti et al. 2015). These sediments are young, dating to Recent time, but likely overlie the older sedimentary units described below. As fossils are 5,000 years in age or older (SVP 2010), this unit is not old enough to preserve fossils.

Therefore, the very young wash deposits in the Project area are assigned low paleontological potential.

However, these sediments likely overlie the sedimentary deposits of Live Oak Canyon and the San Timoteo Formation, which have high paleontological potential. Therefore, areas mapped as very young wash deposits should be considered to have low-to-high paleontological potential, increasing with depth.

The exact depth at which these high potential units are present in the subsurface is not known at this time.

Young axial valley deposits, unit 5 (abbreviated as Qya5 by Matti et al. [2015]). Young axial-valley deposits are found across the Project area interspersed with the younger wash deposits described above and the older alluvial fan deposits described below (Figure 3). These sediments consist of slightly to moderately consolidated sand, mud, and gravel deposited via streams of axial valleys, with those present at the surface in the Project area dating from the uppermost Holocene (Matti et al. 2015). Matti et al. (2015) do not provide a chronologic age for this unit; however, the upper Holocene (equivalent to the Meghalayan Stage) is defined by the International Commission on Stratigraphy as ranging from the present to 4,200 years ago (Cohen et al. 2013).

13 As such, this unit is also not old enough to preserve fossils (SVP 2010) and is also assigned low paleontological potential. Like the young wash deposits above, they also likely overlie the older sedimentary units at an undetermined depth. Therefore, areas mapped as unit 5 of the young axial valley deposits should be considered to have low-to-high paleontological potential, increasing with depth. The exact depth at which these high potential units are present in the subsurface is not known at this time.

Very old alluvial fan deposits, unit 3 (abbreviated as Qvof3 by Matti et al. [2015]). Very old alluvial-fan deposits are present at the surface of the Project area in the northern portion of Calimesa Boulevard (Figure 3). These sediments consist of sand and gravel with muddy sediment present locally and represent the drainage basin of San Timoteo Creek. These sediments are stacked in terrace-riser positions over the underlying sedimentary deposits of Live Oak Canyon (Matti et al. 2015). These sediments date to the middle Pleistocene (likely between 500,000 to 700,000 years old) (Matti et al. 2015) and are likely underlain by older sedimentary deposits of Live Oak Canyon and the San Timoteo Formation. As such, this unit is of an age to preserve fossils.

The locality search from the LACM indicates there are several fossil localities known to the LACM in the vicinity of the Project area from Pleistocene-aged sediments similar to those that are present at the surface of and likely present in the subsurface of the Project area at an undetermined depth. The closest of these is from the San Jacinto Valley, approximately 6.3 miles from the Project area where horse family (Equidae) fossils were found at an unknown depth (LACM 2022). Additional localities known to the LACM (2022) preserved an array of fossils, including horses, camel, peccary, fish, insects, and other invertebrates. A review of the scientific literature indicates that across Riverside County and neighboring Los Angeles County Pleistocene fossils representing a rich Ice Age fauna are often found in similar Quaternary-aged sediments. These include animals still found in North America today, such as deer, bison, sheep, and horses, creatures no longer found in North America, such as camels, lions, cheetahs, and sloths, and extinct creatures such as mammoths, dire wolves, and saber-toothed cats (Jefferson 1991 a and b, Graham and Lundelius 1994, McDonald and Jefferson 2008, Miller 1971, Reynolds and Reynolds 1991). In addition to these iconic large animals, a wide variety of small animals can be preserved as well, including reptiles such as frogs, salamanders, snakes (Hudson and Brattstrom 1977), and birds (Collins et al. 2018, Jones et al. 2008, Miller 1941). These fossils are important for recreating the history of Southern California, in particular studying climate change (e.g., Roy et al. 1996), extinction (e.g., Barnosky et al. 2004, Jones et al. 2008, Sandom et al. 2014, Scott 2010), and paleoecology (e.g., Connin et al. 1998).

As these Pleistocene-aged alluvial sediments are well known to preserve paleontological resources in Southern California, including in the vicinity of the Project area, they are assessed as having high paleontological potential.

Sedimentary Deposits of Live Oak Canyon (abbreviated as Qlo by Matti et al. [2015]). The sedimentary deposits of Live Oak Canyon are not mapped at the surface of the Project area, but exposures of this unit are mapped at the surface just north of the Project area along Singleton Road (Figure 3). These sediments represent fluvial braidplain deposits and are described as unconsolidated and consolidated nonmarine gravels and conglomerates interbedded with sandy and muddy sediment and rock that crops out in low hills and mesas north of San Timoteo Canyon (Matti et al. 2015). Sedimentary deposits of Live

14 Oak Canyon date from the older part of the Pleistocene (likely between 780,000 to 1.2 million years old) (Matti et al. 2015). Given the age and lithology of these deposits, they have the potential to preserve fossils such as described above for the very old alluvial fan deposits, and so are assessed as having high paleontological potential.

San Timoteo Formation, Middle Member (abbreviated as Tstm by Matti et al. [2015]). The Middle Member of the San Timoteo Formation is not mapped at the surface of the Project area, but Matti et al. (2015) show the unit directly to the north and east of Singleton Road. There are four common lithologies within the Middle Member, thick sheets of conglomerate, white to light gray sandstone with slightly conglomeratic sandstone, reddish mudstone and sandstone, and grayish green mudrock (Matti et al. 2015). This member is Pliocene to Pleistocene in age, deposited between 1.2 to 4.0 million years ago (Matti et al. 2015).

The San Timoteo Formation has produced an abundance of paleontological resources, particularly from the San Timoteo Badlands, which are approximately 3 miles southwest of the Project area. The records of the LACM indicate they have five localities from exposures of this unit in the San Timoteo Badlands.

These localities preserved fossils from horses and camels. The online records of the University of California Museum of Paleontology (2022) indicate they have 36 fossil localities from the San Timoteo Formation, which have yielded fossils of 296 vertebrates, primarily mammals but with some tortoises. A review of the scientific literature shows an array of Ice Age megafauna including horse, camel, elephant, sloth, bear, peccary, deer, and a variety of rodents (Albright 1997, Frick 1921, Reynolds and Reeder 1986) have been reported from the San Timoteo Formation. Therefore, the San Timoteo Formation is assessed as having high paleontological potential.

6.2 POTENTIAL IMPACTS TO PALEONTOLOGICAL RESOURCES FROM

PROJECT ACTIVITIES
Should paleontological resources be encountered during construction, their damage or destruction would constitute a direct adverse impact. Therefore, Stantec has developed recommendations for mitigation that will avoid damage or destruction of paleontological resources in the Project area, thus reducing direct adverse impacts to less than significant. It is not anticipated that the Project will pose indirect or cumulative adverse impacts to paleontological resources, as the final Project will not entail increased exposure or erosion of native sediments beyond the duration of the ground disturbance described above.

7.0 RECOMMENDATIONS AND MANAGEMENT

CONSIDERATIONS
As part of the current paleontological assessment, an analysis of existing data consisting of a records search from the LACM and a review of geologic mapping and the scientific literature was conducted in order to assess the potential of the geologic units in the Project area to preserve paleontological resources. The results of this assessment show that geologic units with low paleontological potential are present across the surface of the majority of the Project area, with high potential units present at the surface in one section of the Calimesa Boulevard realignment and likely in the subsurface throughout the

Recommendations and Management Considerations
16 Project area. Project activities are expected to include ground disturbance. Currently available Project plans do not include complete specifications for depth or type of ground disturbance. Should Projectrelated activities encounter paleontological resources, the damage or destruction of those resources would constitute an adverse impact under CEQA. In order to avoid impacts to paleontological resources, Stantec recommends the following mitigation activities for the Project:
• The Project Paleontologist should develop and oversee the implementation of a Paleontological Monitoring and Mitigation Plan tailored to the Project plans (when they are available) that provides for paleontological monitoring of earthwork and ground disturbing activities into undisturbed geologic units with high paleontological potential, whether at the surface or in the subsurface, to be conducted by a paleontological monitor meeting industry standards (SVP 2010 or Murphey et al. 2019). Monitoring recommendations are as follows:
o Paleontological spot checks will be conducted by a qualified paleontological monitor for initial ground disturbance between 3 feet and 5 feet in depth in portions of the Project area mapped as very young wash deposits (abbreviated as Qvywm and Qvyw2 by Matti et al. [2015]) and young axial valley deposits (abbreviated as Qya5 by Matti et al. [2015]).

Should sediments with high paleontological potential be identified during spot checks, full time monitoring will be implemented.
o Full time paleontological monitoring will be implemented once excavations reach 5 feet in depth in areas mapped as very young wash deposits (abbreviated as Qvywm and Qvyw2 by Matti et al. [2015]) and young axial valley deposits (abbreviated as Qya5 by Matti et al. [2015]).
o Full time paleontological monitoring will be conducted for all ground disturbance into previously undisturbed areas mapped as very old alluvial fan deposits (abbreviated as Qvof3 by Matti et al. [2015]).
o The Project Paleontologist may reduce the frequency of monitoring or spot checks should subsurface conditions indicate low paleontological potential. • The Project Paleontologist should develop a Worker’s Environmental Awareness Program training that communicates requirements and procedures for the inadvertent discovery of paleontological resources during construction, to be delivered by the paleontological monitor to the construction crew prior to the onset of ground disturbance. • In the event that paleontological resources are encountered during construction activities, all work must stop within 50 feet of the finds while the paleontological monitor documents the find. The Project Paleontologist shall assess the find. Should the Project Paleontologist assess the find as significant, the find shall be collected and curated in an accredited repository along with all necessary associated data and curation fees. Construction will not resume within the 50-foot radius of the finds until authorized by the Project Paleontologist.

17 Based on the findings in this study and the implementation of the above mitigation recommendations, the proposed Project should not cause an adverse impact to paleontological resources. Therefore, no additional paleontological resources studies are recommended or required at this time. Changes to the Project plans or Project Area from those assessed in this study will require additional assessment for impacts to paleontological resources.

1.0 EXECUTIVE SUMMARY
This firm conducted a Phase I Environmental Site Assessment (ESA) for the Singleton Road Interchange and Calimesa Boulevard Realignment located in Calimesa, California.

This Phase I ESA was conducted in general conformance with American Society of Testing and Materials (ASTM) E1527-13 and All Appropriate Inquiries (AAI) set forth in 40 Code of Federal Regulations (CFR) part 312. This Phase I ESA also incorporates the procedures set forth in the recently approved ASTM E1527-21.

The use of the subject property has historically and recently, dating back to the early 1900s, includes vacant land, dirt and paved roadways (including along street and freeway ROWs), residential structures, a groundwater well, a natural drainage feature that was artificially channeled, farmland (predominantly dryland), and buildings and canopy associated with a preschool campus.

Areas of oil-stained soils, which are anticipated to be surficial (within the upper foot of soil), were observed along or near the sides of the asphalt-paved road along Calimesa Boulevard. At one of these areas of stained soils, along the easterly side of Calimesa Boulevard and approximately 450 feet south-southeast of the intersection at Calimesa Boulevard and Singleton Road, a 5-gallon plastic bucket, labeled as containing hydraulic oil, has a residual amount of liquid in the bottom. No other containers with hazardous materials or wastes was observed at the subject property.

There are five sites, not including the subject property, listed in environmental regulatory databases within 1 mile of the subject property. Based on our research and VES, no environmentally impaired properties have current or former releases of hazardous substances and/or petroleum products that are known to have migrated to and/or impacted the subject property, and therefore, a VEC can be ruled out for the subject property.

Due to the size and nature of the subject property, property owner interviews were not conducted, nor were regulatory agency records requested. However, based on historical topographic maps and aerial photograph images, environmental database report, and online environmental regulatory agency records reviewed, it does not appear these data gaps are significant enough to impact the findings, opinions, and conclusions of this Phase I ESA.

The oil-stained soils observed at the subject property are anticipated to be limited in vertical extent, and are deemed to be a de minimis condition. 1 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
The limited (both in area and time) irrigated farming use of the subject property is not anticipated to have an adverse environmental impact.

The historical use of the subject property or nearby properties for current or historical roadways, including the past US Routes 70 and 99 and current I-10 Freeway, has likely impacted soils at the subject property with aerially-deposited lead (ADL). The most significant ADL impacts are anticipated along the west/southwest end of the subject property.

The approximate 390 cubic yard soil stockpile along the west side of Calimesa Boulevard towards the south end of the subject property appears to be undocumented as to how it was generated and came to be where it is. This soil stockpile may have been generated during the planting of trees in the two areas of the subject property along the westerly side of Calimesa Boulevard, or perhaps some other roadway project. Aside from possible ADL impacts, we do not anticipate the soil stockpile will have an adverse environmental impact.

This assessment has revealed no RECs, CRECs, or significant data gaps in connection with the subject property.

The limited past irrigated farming use of the subject property, ADL, and approximate 390 cubic yard soil stockpile are environmental concerns. The only way to confirm our opinion regarding the potential impact to soils at the subject property from past agricultural irrigated farming, historical use of leaded gasoline in vehicles traveling within or near the subject property (ADL), and the approximate 390 cubic yard soil stockpile along the west side of Calimesa Boulevard towards the south end of the subject property, would be to perform soil sampling and subsequent laboratory analysis and data evaluation. 2 LOR GEOTECHNICAL GROUP, INC.

2.0 INTRODUCTION
During September 2022, this firm conducted a Phase I ESA for the Singleton Road Interchange and Calimesa Boulevard Realignment located in Calimesa, Riverside County, California. This Phase I ESA was conducted with the subject property defined by the roadways being improved or realigned and the associated limits of disturbance.

The approximate location of the subject property within its regional setting is presented on an Index Map (Figure 1).

The Phase I ESA was conducted in conformance with the Standard Practice for Environmental Site Assessments: Phase I ESA Process, ASTM E1527-13, and AAI set forth in 40 CFR Part 312. The purpose was to identify RECs that may be associated with the subject property. A REC means: (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. A controlled recognized environmental condition (CREC) is a REC 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). A historical recognized environmental condition (HREC) is 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 or other property use limitations). An HREC is not a REC.

A de minimis condition is 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 REC nor a CREC.

This Phase I ESA also incorporates the procedures set forth in the recently approved ASTM E1527-21, which is pending approval from the United States Environmental Protection Agency for its compliance with AAI. This Phase I ESA is also intended to satisfy the requirements of a California Department of Transportation (Caltrans) Initial Site Assessment (ISA).

The findings of our Phase I ESA, as well as our opinions, conclusions, and recommendations, are presented within the following sections of this report.

2.1 Exceptions
Certain exceptions in this Phase I ESA to the standards include no interviews conducted with the owners of properties within or adjoining the subject property. Also, no records requests were made to regulatory agencies, including environmental, as the subject property crosses numerous properties and no sites at or adjoining the subject property were identified with significant activities warranting such a request.

2.2 Methodology
The following tasks were completed in order to conduct the Phase I ESA for the proposed project: 1) A general review of the physical setting of the subject property, including topography, geology, and hydrogeology, was performed; 2) Historical fire insurance map images, topographic map images, aerial photograph images, and city directory information, as available, were examined to investigate the past use of the subject property and adjoining properties; 3) The potential for aerially-deposited lead (ADL) along roadways within the subject property or adjoining properties was evaluated; 4) Subject property reconnaissance to assess current conditions of the proposed project and adjoining properties, and visibly identify areas of potential contamination that may impact the subject property; 5) Review of available online environmental regulatory agency records; 6) Federal, state, local, tribal, and proprietary lists and databases were reviewed to ascertain the presence of known environmentally impaired sites within the immediate area, and to determine their impact, if any, to the subject property; and 7) A Vapor Encroachment Screen was conducted to evaluate the subject property for vapor encroachment conditions.

3.0 NON-SCOPE CONSIDERATIONS
The following list (not all-inclusive) of environmental issues are outside the scope of ASTM E1527-13 and E1527-21, and AAI:
• Asbestos-containing building materials unrelated to releases into the environment; • Biological agents;

4.0 PROJECT DESCRIPTION
The proposed project will consist of the realignment of Calimesa Boulevard where it crosses Singleton Road. The new alignment for Calimesa Boulevard will result in a new intersection with Singleton Road roughly 300 feet east of the current intersection. The new alignment for Calimesa Boulevard will also result in a more exaggerated curve in the roadway, including sweeping curves off of the existing alignment. Street improvements along Singleton Road will include expansion of the roadway between the existing alignment for Calimesa Boulevard and the intersection at Beckwith Avenue. Street improvements will generally include concrete curb and gutter with concrete sidewalk, except along the northerly side of Singleton Road, east of the existing alignment for Calimesa Boulevard, and along Caltrans right-of-way (ROW) for the I-10 Freeway where asphalt curbs will be constructed.

Fourteen sheets of drawings with preliminary proposed plans for street improvements, prepared by TKE Engineering, Inc., are provided in Appendix A.

4.1 Current Land Uses
The proposed project is located in a local area of mixed use, including commercial, residential, and vacant land. The commercial uses include a day care/preschool facility, a preschool, a horse ranch, cellular communications towers and associated equipment, and a municipal water agency groundwater well facility.

5.0 USER PROVIDED INFORMATION
ASTM E1527-13 and E1527-21 defines a User as the party seeking to use Practice E1527 to complete an environmental site assessment of the (subject) property. A User may include, without limitation, a potential purchaser of (subject) property, a potential tenant of (subject) property, an owner of the (subject) property, a lender, or a property manager.

Under ASTM E1527-13 and E1527-21, and AAI, specific tasks are assigned to the User that will help identify the possibility of RECs in connection with the subject property.

AAI requires these tasks be performed by or on behalf of a party seeking to qualify for a landowner liability protection to CERCLA liability. These tasks do not require the technical expertise of an Environmental Professional, and are generally not performed by Environmental Professionals performing a Phase I ESA. The User may provide the information gathered from these tasks, including the following:
• Any environmental cleanup liens against the subject property that are filed or recorded under federal, tribal, state or local law;
• Any activity and land use limitations (AULs), such as engineering controls, land use restrictions, or institutional controls that are in place at the subject property and/or have been filed or recorded in a registry under federal, tribal, state, or local law; • Specialized knowledge or experience (that is material to RECs in connection with the property) of the User related to the subject property or nearby properties (for example, is the User involved in the same line of business as the current or former occupants of the subject property or an adjoining property so that the User would have specialized knowledge of the chemicals and processes used by this type of business);

• Relationship of the purchase price to the fair market value of the subject property if it were not contaminated (reason for significantly lower purchase price, such as contamination is known or believed to be present at the subject property); • Commonly known or reasonably ascertainable information about the subject property that would help the Environmental Professional to identify conditions indicative of releases or threatened releases (such as the past uses of the subject property, specific chemicals that are present or once were present at the subject property, spills or other chemical releases that have taken place at the subject property, and any environmental cleanups that have taken place at the subject property);
• Any obvious indicators that point to the presence or likely presence of contamination at the subject property, based on the knowledge and experience of the User related to the subject property; and
• Other information, including the reason why the Phase I ESA is required and/or is being performed, the type of property and type of property transaction (sale, purchase, exchange, etc.), the complete and correct address for the subject property, the scope of services desired for the Phase I ESA, identification of all parties who will rely on the Phase I ESA report, identification of the site contact and how the contact can be reached, any special terms and conditions which must be agreed upon by the Environmental Professional, and any other knowledge or experience with the subject property that may be pertinent to the Environmental Professional (for example, copies of any available prior environmental site assessment reports, documents, correspondence, etc., concerning the subject property and its environmental condition).

Information provided with respect to the above includes the purpose for conducting the Phase I ESA which is to evaluate potential environmental impacts to the roadways proposed for improvement or realignment and the associated limits of disturbance.

The client, TKE Engineering, Inc., and the City of Calimesa, include the parties who will rely on this Phase I ESA report.

6.0 PHYSICAL SETTING
The physical setting of the subject property, including topography, geology, and hydrogeology, are summarized below.
7 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022

6.1 Site Topography
The subject property is situated on various landforms, including hills, a canyon, and alluvial fans, consisting of relatively planar to hilly topography with relatively flat to steep slopes falling in all directions and an overall fall in elevation to the southwest. Elevations across the subject property are estimated to reach a high of roughly 2,390 feet above mean sea level (amsl) in the far northeast end along Singleton Road within a canyon, to a low of roughly 2,290 feet amsl in the far southeast end along Calimesa Boulevard. The hilly area of the subject property within the northwest portion, near and northeast, north, and northwest of the intersection at Calimesa Boulevard and Singleton Road, ranges in elevation from roughly 2,300 to 2,365 feet amsl. Localized changes in elevation are present along roadways and associated with storm drain features, including the earthen and/or concrete-lined drainage channel along the northerly side of Singleton Road.

These localized elevation changes in elevation extend up to roughly 10 feet, but are typically less than 7 feet.

6.2 Regional and Local Geology
The subject property is located within the City of Calimesa, which in turn is situated along the junction of two major geomorphic provinces of southern California, or at the end of the Peninsular Ranges geomorphic province where it meets the Transverse Ranges geomorphic province. The Peninsular Ranges include a series of small northwest-trending mountains, separated by wide flat valleys, that extend from the Los Angeles region southeastward into Baja California. The northern margin of this province butts up against a series of mountain ranges that lie in a transverse direction to the normal northwestern trend, or extend east and west. These mountains include the Santa Monica mountains, the San Gabriel Mountains, and the San Bernardino Mountains. In the Calimesa locality, these two major provinces are termed the Peninsular Ranges Block to the south and the San Bernardino Mountains Block to the north, and separated by a series of complex faults known collectively as the San Andreas fault zone. In this tectonically complex area, the Peninsular Ranges block is generally sliding to the northwest, while partially being thrust underneath the San Bernardino Mountains block. Therefore, the resulting faults end up with a complex mix of strike-slip and thrust faults. The Banning and San Andreas faults, both northwest of the subject property, as well as the San Jacinto fault to the southwest, are all strike-slip faults with right lateral offsets. However, the San Gorgonio Pass fault zone, which lies to the southeast of the subject property, is a result of compressional thrust faulting. In addition, differential movement along these faults has even led to the formation of the Beaumont Plains fault zone which is a series of tension, or pull-apart, faults which 8 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
lie to the southeast. Therefore, the topography of the land in this region has been drastically altered by differing tectonic forces. The subject property itself is located along the northwestern margins of a relatively broad fan-like surface known as the Beaumont Plain which extends from Calimesa southeast to Banning. This plain, along with the Badlands to the west, is the result of erosion of the mountains onto a valley-like setting, then uplifting and offsetting of the region by interactions along and between the San Andreas and San Jacinto faults, then continued offsetting of the region along the San Andreas fault, and finally incising by drainages flowing from the northeast to the southwest.

The basement rocks in this region are considered to be igneous and metamorphic crystalline rocks, none of which are exposed at the subject property. These rocks have been covered with a relatively thick sequence of sediments deposited from streams flowing southwest from the mountains to the east and southeast. The hills nearby the subject property are underlain by sedimentary deposits of these types which either are members of, or correlate to members of, the San Timoteo Formation. The San Timoteo Formation is a sedimentary unit of lacustrine and fluviatile sandstones, siltstones, and gravels that were deposited in large alluvial fans, along stream beds, and within shallow lakes between the San Jacinto fault and the San Andreas fault during Pliocene to mid Pleistocene times (about 1 to 2 million years ago). The subject property itself is underlain by alluvial materials. The majority of these are identified as very young wash deposits comprised of very slightly to slightly consolidated sand and gravelly sediment in active channels and young axial-valley deposits comprised of slightly to moderately consolidated sandy, muddy, and gravelly sediment deposited by through-going streams of axial valleys by the USGS (Matti et al., 2015), and alluvial sand, gravel, and clay of level areas by Dibblee and Minch (2003). Minor units of very old alluvial-fan deposits of sandy and gravelly deposits mapped by Matti et al. (2015), and identified as older surficial sediments comprised of weakly indurated alluvial fan deposits derived from local terrains of alluvial sand and gravel by Dibblee and Minch (2003), are present within the elevated area northeast of the intersection of Singleton Road and Calimesa Boulevard.

Information available from the United States Department of Agriculture (USDA) Natural Resources Conservation Service soil web survey indicates the majority of the subject property is underlain by Hanford coarse sandy loam with lessor units of Terrace escarpments, Tujunga loamy sand, channeled, and Hanford loamy fine sand (2022).

Various physical soil properties as presented by the USDA are presented below:

As previously noted, the subject property lies near the middle of a large wedge-shaped area in between the San Jacinto fault, located approximately 7.8 kilometers (4.8 miles) to the southwest and the San Andreas fault which lies just over 9.5 kilometers (5.9 miles) to the northeast. Both of these faults are considered to be major active faults which move in a lateral fashion with the northwest portions offset to the southeast during earthquakes.

This type of motion is called right lateral strike-slip. The San Andreas fault is considered to be the major tectonic feature of California, separating the Pacific plate and the North American plate. While estimates vary, the San Andreas fault is generally thought to have an average slip range on the order of 24 millimeters per year (mm/yr), and is capable of generating large magnitude events on the order of 7.5 or greater.

The San Jacinto fault zone is a sub-parallel branch of the San Andreas fault zone, extending from the northwestern San Bernardino area, southward into the El Centro region.

It is believed that the San Jacinto fault zone has an average slip rate of about 12 mm/year, and is capable of producing an earthquake magnitude on the order of 6.5 or greater.

Lying in between these two faults are numerous smaller faults with varying types of motion.

Perhaps the largest of these, based on length and estimated amounts of past displacement in the region around the subject property, is the Banning fault. Based on mapping conducted by the United States Geological Survey (USGS), the Banning fault bifurcates off of the San Andreas fault just north of Indio, then extends through the Banning-Beaumont pass area and into the Calimesa area with the portion of this fault located beyond the Calimesa area not well defined (Matti et al., 1992). According to this same study, the reason the northern end is not well exposed is because the portion of this fault located northwest of Beaumont has been inactive since earliest Pleistocene time (1.8 10 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
million years ago) and has since been covered with alluvial sediments. Regardless of this, the State of California has placed the Calimesa portion of the Banning fault within an Earthquake Fault Zone on their maps of the Alquist-Priolo Earthquake Fault Zones of California. According to this map, at its closest approach, the Banning fault lies approximately 1.3 kilometers (0.8 mile) northeast of the subject property. At this location, the fault is a prominent feature exposing scarps which juxtapose highly sheared greenish gray metamorphic rocks from the older alluvial sequence common at the subject property.

Differential movement along these faults discussed above has resulted in the extension of the Beaumont Plain. This has created a series of northwest-trending en-echelon fault scarps, referred to as normal faults, in which the center block drops downward along in irregular fault line. These have collectively been named the Beaumont Plain fault zone, which may have some thrusting motion along the northern portions. The motions and activities of these faults is poorly understood. Therefore, the County of Riverside included the mapped locations of these faults within County Fault Hazard Management zones, which require that prior to development these faults should be addressed. The approximate eastern half of Singleton Road lies within a County Fault Hazard Management zone due to several previously mapped northwestern extension of a fault, most likely associated with the Beaumont Plain fault zone, which was shown as cutting across this portion of the subject property in two locations, which the County Zone termed the Cherry Valley fault (CRTLMA, 2022).

Due to the subject property’s close proximity to the faults described above, it is reasonable to expect a relatively strong ground motion seismic event to occur during the lifetime of the proposed development on the subject property. Large earthquakes could occur on other faults in the general area, but because of their lesser anticipated magnitude and/or greater distance, they are considered less significant than the faults described above from a ground motion standpoint.

According to the County of Riverside, the subject property lies within an area of low to moderate liquefaction potential (CRTLMA, 2022).

The majority of the subject property lies on a relatively flat surface. The occurrence of mass movement failures such as landslides, rockfalls, or debris flows within such areas is generally not considered common. No such features are identified on regional geologic maps (Matti et al., 2015; Dibblee and Minch, 2003).

6.3 Hydrogeology
The subject property is situated in the northeast portion and near the northerly boundary of the San Timoteo Subbasin, which underlies Cherry Valley, the City of Beaumont, and south end of the City of Calimesa in southwestern San Bernardino and northwestern Riverside Counties. The subbasin is bounded to the north and northeast by the Banning fault (located approximately 0.8 mile northeast of the subject property) and impermeable rocks of the San Bernardino Mountains, Crafton Hills, and Yucaipa Hills, on the south by the San Jacinto fault, on the west by the San Jacinto Mountains, and on the east by a topographic drainage divide with the Colorado River Hydrologic Region. The surface is drained by Little San Gorgonio Creek and San Timoteo Canyon to the Santa Ana River.

Groundwater is found in alluvium and San Timoteo Formation. Holocene age alluvium, which consists of unconsolidated clay, silt, sand, and gravel, is the principal water-bearing unit in this subbasin. The Pliocene-Pleistocene age San Timoteo Formation consists of alluvial deposits that have been folded and eroded. These deposits are widely distributed and principally composed of gravel, silt, and clay, with comparatively small amounts of calcite-cemented conglomerate. The clasts are chiefly granitic, with lesser amounts of volcanic and metamorphic pebbles and cobbles. The total thickness of the San Timoteo Formation is estimated to be between 1,500 and 2,000 feet, but logs of deep wells near the central part of the subbasin indicate water-bearing gravels to depths of only 700 to 1,000 feet (California Department of Water Resources, 2004).

Local groundwater level measurements were researched at the California Department of Water Resources (DWR) online Water Data Library (California DWR, 2022). The closest groundwater well found in this search appears to coincide with the Yucaipa Valley Water District (YVWD) Well 48 located near the northerly side of the subject property within a fenced compound at 35290 Singleton Road, on the other side of a concrete-lined drainage channel and roughly 700 feet east-northeast of the intersection at Calimesa Boulevard and Singleton Road. However, the information provided online for this well, indicated to be State Well No. 02S02W24L001S is lacking the local well name, and according to the well data from the Cooperative Well Measuring Program, Spring 2022, YVWD Well 48 is associated with State Well No. 02S02W24L002S (Watermaster Support Services et al., 2022). The DWR groundwater level data for State Well No. 02S02W24L001S from June 1998 to April 1999 ranges from approximately 145 to 159 feet below the ground surface (bgs). The Cooperative Well Measuring Program groundwater level data for YVWD Well 48 from August 1993 to March 2022 ranges from approximately 26 to 317 feet bgs.

Some of the Well 48 water levels were recorded during pumping of the well, and the most 12 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
shallow water level appears to be erroneous, as the next shallowest groundwater levels are in the 140 feet bgs range.

Based on the above historical and recent groundwater level data, groundwater beneath the subject property is anticipated to be greater than 100 feet bgs. The local groundwater flow direction is estimated to be southwesterly, coincident with the overall fall in local ground surface topography.

7.0 HISTORY OF SITE USAGE
To obtain a history of previous site usage, a search was conducted for historical Sanborn Fire Insurance Maps, topographic maps, aerial photographs, and city directory information.

7.1 Sanborn Fire Insurance Maps
No coverage of historical fire insurance maps was available for the subject property or adjoining properties. The Certified Sanborn® Map Report from EDR, which indicates the subject property is unmapped, is provided in Appendix B.

7.2 Topographic Maps
Historical topographic map images of the quadrangle(s) that include the subject property, at a scale of approximately 1"=2,200', provided by EDR from 1901, 1942, 1943, 1953, 1967, 1979, 1996, 2012, 2015, and 2018, were reviewed. Five of these map images are seamed together from multiple quadrangles. The main quadrangle representing the “1996" map appears to be from 1968, and it is unclear if the seamed quadrangle at the north end of this image is from 1994 or 1996. The EDR Historical Topographic Map Report, with the approximate subject property boundaries shown on the topographic map images, is provided in Appendix C. Online historical topographic map images of the subject property and surrounding properties were also utilized to enhance our review (NETR, 2022; USGS, 2022).

The 1901 map image, derived from a map at a scale of 1:125,000, shows the subject property and immediate surrounding properties as vacant land. Over 200 to 400 feet away from the subject property to the southeast is a dirt road and drainage feature that may actually represent the beginnings of those within the subject property at present day along Singleton Road. Some roads and over half a dozen residence-sized structures are indicated in the local area. The closest residence-sized structure to the subject 13 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
property is located at the northerly end of a dirt road over 500 feet to the north-northwest.

Over 1.5 miles to the southwest of the subject property is a railroad track (Southern Pacific Railroad) and adjacent road along the present day San Timoteo Canyon Road.

The 1942 and 1943 map images, derived from maps at a scale of 1:62,500, shows a lot of changes to the subject property and surrounding area. A paved road, curving and somewhat meandering, is indicated within the subject property along the present day alignment for Singleton Road. A natural drainage feature is shown near and along the northwest side of Singleton Road. The northeast end of the subject property along Singleton Road appears to be situated in a canyon along side this natural drainage feature.

Nearby residence-sized structures are shown in nearly all directions from the subject property. A dirt road heads northeast across the subject property towards the northwest end, and then east offsite to a residence-sized structure. Another dirt road is shown heading in a northerly direction from Singleton Road, beginning at the subject property, indicated to terminate at the northeast end of a relatively small canyon. This dirt road begins along the northwest side of Singleton Road near and northeast of the present day proposed new alignment for Calimesa Boulevard. Offsite, heading to the southeast towards a residence-sized structure from Singleton Road, is a dirt road roughly along the present day alignment for Beckwith Avenue. United States (US) Routes 70 and 99 are indicated for a roadway generally along the present day I-10 Freeway which is near and generally west/southwest of the subject property, but the roadway encroaches into the subject property in the far northwest and far south ends. A road branching off of this roadway crosses through the south end of the subject property and appears to fall along the present Calimesa Boulevard at and southeast of the subject property, eventually entering into and running coincident with the present day I-10 Freeway alignment.

The 1953 map image is derived from a map at a scale of 1:24,000, and shows the subject property and surrounding area somewhat the same as shown in the 1942 and 1943 map images, with additional development in the area, including residential development, water reservoirs, and Calimesa Airport located over 1,000 feet to the southwest of the subject property. Two residence-sized structures are shown along the westerly boundary of the subject property, near and just south/southeast of Singleton Road, and are likely within the subject property, based on historical aerial photographs. A few residence-sized structures, including a canopy structure, are located near and west/southwest of the subject property on either side of Singleton Road, between the subject property and 4-lane, divided roadway along US Routes 70 and 99. A small agricultural grove is depicted adjacent to the east of the south end of the subject property. The dirt road along Beckwith Avenue has been extended to the southeast, and there are now several residence-sized 14 LOR GEOTECHNICAL GROUP, INC.

September 26, 2022
structures along or near its northeast side. A groundwater well is indicated near the northwest side of Singleton Road towards the northeast end of the subject property.

This well is coincident with the present day dirt entrance drive for the offsite Fascination Ranch (horse ranch and event venue). Two northerly-trending dirt roads, a partial one of which was previously shown in the 1942 and 1943 map images, extend from Singleton Road within the subject property near or in relative close proximity to and northeast of the present day proposed new alignment for Calimesa Boulevard. These dirt roads lead to several residence-sized structures. Near and outside the northerly boundary of the subject property and within approximately 900 feet to the southeast of the northeast end of the subject property is a residence-sized structure and a rectangular canopy structure.

The residence-sized structure is located very near the subject property boundary, and may actually be located within the bounds of the subject property.

The 1967 and 1979 map images are largely the same, derived from maps at a scale of 1:24,000, and show the subject property and surrounding area with some significant changes. Calimesa Boulevard, a frontage road along or near the easterly side of US Routes 70 and 99, now indicated to be the I-10 Freeway, is depicted along its present day alignment, crossing through the subject property. With the construction of Calimesa Boulevard, US Routes 70 and 99/I-10 Freeway no longer encroach into the subject property in the far northwest and far south ends. The few residence-sized structures, including a canopy structure, located between the subject property and I-10 Freeway are absent, and the present day westbound off-ramp for Singleton Road is shown.

The agricultural grove adjacent to the east of the south end of the subject property is gone.

The groundwater well coincident with the present day dirt entrance drive for the offsite Fascination Ranch is no longer indicated. One of the dirt roads near and northeast of the present day proposed alignment for Calimesa Boulevard, previously shown leading to a residence-sized structure, is gone, and either the structure is shown in a location closer to Singleton Road, or it is gone and a new structure is present. Two new, offsite residence-sized structures are shown near the northerly boundary of the subject property, within roughly 1,300 feet to the southeast of the northwest end of the subject property, including one situated near a rectangular canopy that is no longer depicted. A new groundwater well is depicted at the subject property within approximately 300 feet to the north-northeast of the intersection at Calimesa Boulevard and Singleton Road. The 1979 map image shows additional residence-sized structures added, including one at the subject property in the south portion along the east side of Calimesa Boulevard. Singleton Road has been modified, and now falls along the present day alignment, with a section of paved road along the old alignment remaining at the present day preschool/day care facility (not shown) near the intersection at Beckwith Avenue and Singleton Road. Less of the drainage 15 LOR GEOTECHNICAL GROUP, INC.

feature near and northwest of Singleton Road is shown (as a “blue-line stream”), possibly due to artificial channelization of it. The Calimesa Airport and several of the reservoirs previously depicted in the local area are absent with one new reservoir depicted in the 1979 map image.

The “1996" map image was determined to be from 1968, based on comparison with an online topographic map image (NETR, 2022). This map image appears to essentially be the same as the EDR 1967 topographic map image, but without topographic lines of elevation shown.

The map images from 2012, 2015, and 2018 are largely the same, derived from maps at a scale of 1:24,000. These map images generally do not show structural features. Based on the infrastructure shown, increased structural development has occurred within the local area of the subject property, including the present day senior community (Sharondale) along the southeast side of roughly the east half of the subject property along Singleton Road. Beckwith Avenue, the far northwest end of which is located within the subject property, is now shown as a paved road, likely developed along with Sharondale.

7.3 Aerial Photographs
Digital aerial photographs provided by EDR, from 1938, 1949, 1953, 1959, 1961, 1968, 1975, 1978, 1985, 1989, 1996, 2002, 2006, 2009, 2012, and 2016, were reviewed to investigate the past use of the study area and the surrounding properties. Google Earth Pro computer program (2022) recent (1996 to 2022) and online (Nationwide Environmental Title Research, LLC, 2022) historical digital aerial images were used to enhance our review and/or provide supplementary review. Copies of the historical aerial photographs provided by EDR are provided in Appendix D.

A brief summary of the site and surround conditions during the various times, as reflected in the EDR aerial photographs, is given below.

The EDR 1938 digital aerial photograph image shows much of the subject property and immediately surrounding properties as vacant, undeveloped land, either in a relatively natural state, under dryland farming, or fallow farm land. A roadway located along what the historical topographic map images indicate is US Routes 70 and 99, generally along the present day I-10 Freeway which is near and generally west/southwest of the subject property, encroaches into the subject property in the far northwest and far south ends. 16 LOR GEOTECHNICAL GROUP, INC.

September 26, 2022
The portion of this roadway within the south end of the subject property appears to have asphaltic materials recently placed with no traffic lanes indicated, and is likely under construction. Roughly along the present day Singleton Road ROW is a natural drainage feature evidenced by a scoured, likely sandy stream bed. This drainage feature is artificially channelized at present day along the north side of the Singleton Road ROW. Also roughly along the present day Singleton Road ROW is a dirt road that is somewhat winding, and curves below (to the south and southeast) and outside the subject property at and near the present day Beckwith Avenue before curving back into the subject property. This dirt road terminates offsite at the roadway for US Routes 70 and 99. Other more minor dirt roads are present at the subject property, the most prominent of which is a dirt road that heads in a west-southwesterly direction along the south side of a canyon that originates east of the north end of the subject property and essentially ends at or near the westerly side of the subject property, coincident with the present day Calimesa Boulevard and Montessori Preschool campus, towards the northwest end of the subject property. Between the west/southwest central portion of the subject property and the roadway along US Routes 70 and 99 are two or three structures that likely include a residence and outbuildings.

Within a few hundred feet to the north of the northwest end of the subject property are two structures, likely including a residence. West/southwest of the subject property over 100 feet away are two or three agricultural groves.

The EDR 1949 digital aerial photograph image shows the subject property and surrounding local area largely the same as in the 1938 aerial image. A new residential property which appears to have some agricultural activity is now located at the east/southeast corner of US Routes 70 and 99 and the dirt road roughly coincident with the present day Singleton Road ROW. The roughly rectangular area associated with this property appears to include a couple structures with numerous trees present, the mature of which do not appear to be in the pattern of an agricultural grove, and the younger of which are in a small area in a grid pattern at the subject property. Some of the mature trees are present within the subject property, including along the southerly side of the dirt road roughly along the Singleton Road ROW. One of the structures at this property appears to fall along the westerly boundary of the subject property. The roadway for US Routes 70 and 99 running through the south end of the subject property is completed with traffic lanes indicated. Adjacent to the east of the south end of the subject property is an agricultural grove. Adjacent to the north-northwest of this grove appears to be a band of irrigated farm land, a small portion of which encroaches in the subject property within the far south end. Apparently associated with the offsite property between the west/southwest central portion of the subject property and the roadway along US Routes 70 and 99, are two small objects or structures at the subject property in close proximity to the westerly boundary. A small dirt road now leads 17 LOR GEOTECHNICAL GROUP, INC.

north from the dirt road within the subject property and roughly along the present day Singleton Road ROW. This dirt road crosses the natural drainage feature at the subject property and continues offsite, eventually leading to what may be three residences, the first of which has a small agricultural grove. Starting east of this dirt road and continuing along the north side of the dirt road roughly along the present day Singleton Road ROW, is an area with dense vegetation that may be largely comprised of trees, close to half of which is located on adjacent property offsite. The dirt road along the south side of the canyon offsite and coming into and terminating towards the northwest end of the subject property is now truncated, ending at an apparent residence property where there may be a structure located just within the subject property and near a northerly boundary. Towards the far northwest end of the subject property is another dirt road that crosses the subject property, terminated at US Routes 70 and 99 roadway. Along this dirt road, and offsite to the east-northeast, are small objects or structures. Additional residences are present in the local area, including one approximately 400 feet north-northwest of the northeast end of the subject property.

The EDR 1953 digital aerial photograph image shows the subject property and surrounding local area largely the same as before. The roadway along US Routes 70 and 99 is now a divided roadway, with the original roadway more narrow along the easterly of the divided travel lanes. The dirt road roughly along the present day Singleton Road has been graded wider. Most of the lower elevation areas of the northwest end of the subject property appear to be under dry land farming or were mowed or disced for weed control. Due to the somewhat poor quality of the digital image it is difficult to discern, but some of the trees at the subject property and offsite to the west, associated with the residential/agricultural property at the east/southeast corner of US Routes 70 and 99 and the dirt road roughly along the present day Singleton Road ROW are gone. The lower elevation areas within the area in the northwest central portion of the subject property include a small dirt road and faint trails or cleared paths, one of which is in a trapezoidal pattern. Within 70 feet of the northwest subject property boundary and north of the present day intersection at Beckwith Avenue and Singleton Road is a rectangular structure and smaller square structure which may include a residence. More faint dirt roads across the subject property were previously shown leading to the location of these structures, but are generally now more well worn.

A faint dirt road leads southeast from the dirt road roughly along the present day Singleton Road ROW towards the northeast end of the subject property. This dirt road leads to an apparent residence and small outbuilding. The agricultural groves to the southwest and beyond US Routes 70 and 99 are gone, with irrigated farming present across much of the areas of the former groves.

The EDR 1959 digital aerial photograph image shows the subject property and surrounding local area essentially the same as before. Additional trees and a structure are present at the subject property, associated with the residential/agricultural property located at the east/southeast corner of US Routes 70 and 99 and the dirt road roughly along the present day Singleton Road ROW. Within most of the lower elevation areas within the northwest central portion of the subject property appears to be cleared vegetation and possibly some disturbed soils. The band of irrigated farm land previously shown encroaching into the far south end of the subject property is now under dryland farming. There appears to be a narrow, poorly asphalt-paved road along the winding dirt road roughly along the present day Singleton Road ROW.

The EDR 1961 digital aerial photograph image shows the subject property and surrounding local area essentially the same as before. At the subject property, within the area associated with the residential/agricultural property at the east/southeast corner of US Routes 70 and 99 and the paved road roughly along the present day Singleton Road ROW, are two small rectangular areas that appear to be under irrigated farming.

Structures both at the subject property and offsite, associated with the residential property located between the central portion of the subject property and US Routes 70 and 99, are gone.

The EDR 1968 digital aerial photograph image shows the subject property and surrounding local area somewhat the same as before. The roadway along the present day Calimesa Boulevard has been constructed, including the section crossing through the subject property. Along with this construction, the I-10 Freeway and associated roadways, including the Singleton Road overpass and Singleton Road off-ramp for the westbound lanes, are now present. The Singleton Road off-ramp is located very near and west of the subject property. A 2-lane, asphalt-paved road along Singleton Road extends approximately 550 feet east of the intersection with Calimesa Boulevard. The construction of Calimesa Boulevard split the onsite area associated with the residential/agricultural property that previously extended to the east/southeast corner of the old US Routes 70 and 99 and dirt road roughly along the Singleton Road ROW. The larger east portion of this division includes rows of trees, a rectangular structure that is likely a mobile home, and most of a rectangular area that could be irrigated pasture or farm land. The smaller west portion of this division includes numerous mature trees, possibly an asphalt-paved access road off of Calimesa Boulevard, and what appear to be several structures, some of which are offsite or encroach into the subject property. The far west side/end of this smaller west division is offsite. Some vacant areas are present between Calimesa Boulevard and the westerly boundary of the subject property, likely part of the I-10 Freeway ROW. 19 LOR GEOTECHNICAL GROUP, INC.

The agricultural grove adjacent to the east of the far south end of the subject property has been removed. A small residence appears to have been built within 100 feet to the northeast of the northwest portion of the subject property. A mobile home park has been added over 500 feet northeast of the northwest end of the subject property.

The EDR 1975 digital infrared aerial photograph image is of poor quality, but the subject property and surrounding local area appear largely the same as previously shown.

The asphalt-paved road along Singleton Road has been extended along the present day alignment to the east and northeast within the subject property and beyond. This extension resulted in the removal of some of the area with trees near the present day intersection at Beckwith Avenue and Singleton Road. The drainage feature previously winding along a natural course roughly along the Singleton Road ROW has been artificially channeled, including an approximate 600-foot section of concrete-lined channel at and towards the west end near the northeast corner of the intersection at Calimesa Boulevard and Singleton Road. A couple areas with residential and associated structures with dirt roads leading to the old Singleton Road, near the northeast portion of the subject property, are absent. A fire break has been disced along or near the edge of a field that encroaches into the south portion of the subject property towards the south end. Approximately 250 feet northeast of the northwest end of the subject property, along a ridge line, a residence has been added.

The EDR 1978 digital aerial photograph image does not include coverage of the northwest end of the subject property, nor much of the surrounding adjacent property. However, the subject property and surrounding local area appear essentially the same as previously shown. Over 300 feet northeast of the far northwest end of the subject property, situated at the base of hilly topography, a rectangular structure, possibly a mobile home, has been added.

The EDR 1985 digital infrared aerial photograph image is of somewhat poor quality, but the subject property and surrounding local area appear largely the same as previously shown.

Singleton Road has been widened within the central and northeast portions of the subject property. Beckwith Avenue has been paved in asphalt along an approximate 500-foot section, beginning at the intersection with Singleton Road. The road work along Beckwith Avenue and Singleton Road are associated with the beginning construction of the present day Sharondale senior community which has some open space or park areas, numerous mobile homes, with many more still to be placed. Recent asphalt paving along Singleton Road across and beyond the subject property appears to have occurred. Some recent asphalt pavement along Calimesa Boulevard is evident as well. An area of cleared 20 LOR GEOTECHNICAL GROUP, INC.

vegetation, divided into three sections by fencing and/or dirt drive, is present offsite to the north of the central portion of the subject property. This cleared area has structures along its east side which may include a couple residences, and may be the beginnings of the present day Fascination Ranch (horse ranch and event venue). Three rectangular objects, likely truck trailers and/or storage units, are located at the subject property along a northerly boundary near the northwest end of the subject property.

The EDR 1989 digital infrared aerial photograph image is of better quality than the previous image. The subject property and surrounding local area appear to be largely the same as previously shown. Recent asphalt paving appears evident along Calimesa Boulevard across and beyond the subject property. A residence has been added along the southerly boundary of the subject property, within the area of dense trees present near the intersection at Beckwith Avenue and Singleton Road. The Sharondale senior community appears completed and essentially the same as at present day. Additional structures and cleared areas are present offsite to the north of the central and northeast portions of the subject property, most of which is likely associated with the present day Fascination Ranch.

The EDR 1996 digital aerial photograph image is of somewhat poor quality, but the subject property and surrounding local area appear essentially the same as previously shown.

A section of the old Singleton Road along the south side of the area with dense trees near the intersection at Beckwith Avenue and Singleton Road has been paved in asphalt.

A rectangular structure along the north side of this recently paved section of the old Singleton Road, possibly an outbuilding or detached garage, has been added. The main building for the YVWD Well 48 present day facility, near and north of the central portion of the subject property, is present. The small residence within 100 feet to the northeast of the northwest portion of the subject property has been expanded to the size it is at present day. The residential property along the northerly boundary and near the northwest end of the subject property appears to be mostly cleared of structures and objects, and the three truck trailers and/or storage units associated with this property, but previously shown at the subject property, are gone.

The EDR 2002 digital infrared aerial photograph image is of somewhat poor quality, but the subject property and surrounding local area appear largely the same as previously shown.

A small structure appears to have been added to the north of the main building at the YVWD Well 48 facility, likely the present day emergency backup electric generator.

The main building for the present day Montessori Preschool campus, along with associated landscaped areas and asphalt-paved drive and parking areas has been added along the northerly and easterly sides of the northwest portion and end of the subject 21 LOR GEOTECHNICAL GROUP, INC.

property. The west and south ends of this present day preschool campus, including landscaped areas and asphalt drive and parking areas, encroach into the subject property.

An asphalt-paved access road appears to have been recently paved starting at the northeast corner of the present day preschool campus, heading in an easterly direction and then turning back to a westerly direction, and terminating at a residence on a ridge line.

A widened area of asphalt pavement is extended in an easterly direction from the road along Calimesa Boulevard, coincident with the newly added present day preschool campus. The structures located along either side of Calimesa Boulevard, likely including a mobile home and other residence, within the agricultural/residential property previously split by the construction of Calimesa Boulevard, appear to be absent with concrete foundation slabs remaining. Trees have been planted in areas along the westerly side of Calimesa Boulevard, including in an area adjacent to the north of Singleton Road and another area towards the south end of the subject property.

The EDR 2006 digital aerial photograph image is of poor to moderate quality. The subject property and surrounding local area appear largely the same as previously shown.

There appear to be two rectangular structures or storage units located near and south of the main building at the present day preschool campus, located immediately offsite to the north of the subject property. The Google Earth Pro aerial image from June 2003 shows these structures or storage units to be present. Grading for the present day tract of single-family homes, whose southern tip is located north of the northeast end of the subject property, is under way.

The EDR 2009 digital aerial photograph image is of poor to moderate quality. The subject property and surrounding local area appear largely the same as previously shown.

The offsite tract of single-family homes to the north of the northeast end of the subject property appears to be completely graded with no construction started, except for concrete-lined ditches for storm water along slopes bordering the tract. A Google Earth Pro aerial image from June 2009 shows the present day cellular communications tower located approximately 530 feet east-northeast of the northwest end of the subject property, addressed 9530 Calimesa Boulevard. A Google Earth Pro aerial image from November 2009 shows a fenced staging area adjacent to the west/southwest of the area planted with trees at the subject property north of Singleton Road and along the westerly side of Calimesa Boulevard. This offsite staging area includes numerous lengths of pipe, work trucks, heavy equipment, and a storage unit. Most of the pipe is being stored outside and northwest of the fenced area. This area is cleared of all the trucks, equipment, pipe, etc. by the March 2011 Google Earth Pro aerial image.

The EDR 2012 digital aerial photograph image is of moderately good quality, and shows the subject property and surrounding local area essentially the same as previously shown.

A circular area of black material, likely asphaltic, is evident at the subject property, located in a bare dirt area along the south side of Singleton Road, approximately 200 feet east of the intersection at Calimesa Boulevard and Singleton Road. The offsite housing tract north of the northeast end of the subject property is under construction.

The EDR 2016 digital aerial photograph image is of good quality, and shows the subject property and surrounding local area essentially the same as previously shown. Much of the offsite tract of single-family homes to the north of the northeast end of the subject property is constructed. Two small rectangular objects or structures, likely storage units, are present adjacent to the south of the southwest corner of the main building for the present day Montessori Preschool. The two previously shown structures or storage units east of these smaller objects are gone. The Google Earth Pro image from October 2016 shows two rectangular structures, possibly modular buildings, and concrete pavement where the two previously shown structures or storage units were located.

The Google Earth Pro digital aerial images from 2016 to 2021 show the subject property and surrounding local area essentially the same as previously shown. Over this time period, the tract of single-family homes to the north of the northeast end of the subject property was completed. The December 2020 aerial image shows the present day cellular communication tower located approximately 150 feet north of the northwest end of the subject property. The August 2019 aerial image shows two additional rectangular structures similar to the two previously shown south of the main building at the Montessori Preschool. These two newer structures encroach into the subject property. A square canopy structure within a rectangular fenced area is shown east of these two newer structures in the August 2021 aerial image.

7.4 City Directory
Historical city directory information (image report) for listings of addresses along or near the subject property were researched by EDR, including along Calimesa Boulevard and Singleton Road, where commercial listings of potential environmental concern to the subject property are of interest. EDR’s research included directories from the years spanning 1971 to 2017, with available listings spanning from 1990 to 2017. The EDR-City Directory Image Report is provided in Appendix E.

Many of the listings along or near the subject property are residential. Commercial listings along Calimesa Boulevard include Oak Valley Family Church at 9530 and Ever Grand Carriage & Pony Company at 9950 in 2000, and TMobile at 9480 and Community Celebration Center at 9580 in 2017. Commercial listings along Singleton Road include Cunningham Davis Corp. and Tonto Performance Horses at 35600 in 2005, Westec Security at 35600 in 2014, and Cunningham Davis Corp. and Westec Security, LLC at 35600 in 2017.

8.0 AERIALLY-DEPOSITED LEAD
Throughout California, lead is regularly detected in soils adjacent to roadways, associated with the past combustion of leaded gasoline fuel in vehicles which was used until January 1, 1996 when its use was banned by the Clean Air Act. This potential lead impact to soils from past leaded gasoline combustion is referred to as aerially-deposited lead (ADL). The lead impact in soils from ADL can be present at concentrations exceeding background levels, and tends to decrease with distance from the roadway, and with depth in the soil profile. ADL is considered to be an environmental concern for the subject property at or near the existing and former roadways. Based on historical research, including reviews of aerial photograph images and topographic map images, the far west/southwest end of the subject property, where present and past Calimesa Boulevard and off-ramp and roadway associated with the I-10 Freeway have been present or located nearby, is anticipated to have the highest potential for ADL-impacted soils.

9.0 SUBJECT PROPERTY RECONNAISSANCE
A reconnaissance of the subject property was conducted on September 14, 2022 by Mr. Mathew L. Hunt of this firm. The purpose of the reconnaissance was primarily to ascertain, through visual observation, the use, storage, generation, release, and disposal of hazardous materials or wastes on and adjacent to the subject property. A color aerial image with approximate subject property boundaries was used during our reconnaissance, and is presented on Figure 2.

The subject property is irregular in shape, and is generally comprised of linear corridors along existing or proposed public street ROWs. The far west portion of the subject property flares out to the north-northwest and to the southeast along Calimesa Boulevard, and includes the intersection at Calimesa Boulevard and Singleton Road.

Calimesa Boulevard is an asphalt-paved, generally unimproved, 2-lane roadway with some vegetation present, including landscaped trees, bushes, and grass, and natural vegetation. 24 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
At Monty’s Montessori Preschool near the northwest end, Calimesa Boulevard is wider, including multiple turn lanes, and includes an approximate 150-section of concrete sidewalk and curb and gutter. The far west portion of the subject property spans approximately 0.5 mile and bulges out to the east-northeast to include the proposed new alignment for Calimesa Boulevard. Aside from the hilly areas northeast, north, and northwest of the intersection at Calimesa Boulevard and Singleton Road, much of this bulged out area includes relatively flat land that is undeveloped and has been disced for weed control in the relative recent past, with relatively sparse weeds present, except within the far south portion of the subject property south of an old tree line where discing has only been performed for fire breaks. The remainder of the subject property is situated along a corridor largely defined by Singleton Road and associated ROW heading east-northeast from the far west portion of the subject property, then curving to the northeast.

Singleton Road is an asphalt-paved, generally unimproved, 2-lane roadway with some vegetation present, including landscaped trees, bushes, and ornamental plants, and natural vegetation. Concrete curb and gutter, associated with the Sharondale senior community, is located along the southeast side of Singleton Road. At the far northeast end of Singleton Road within the subject property is an asphalt-paved, partially improved, 4-lane roadway. The corridor along the Singleton Road ROW starts out at approximately 135 feet wide, extending to approximately 155 feet wide at the intersection with, and include a short section of Beckwith Avenue, and then narrows to approximately 105 feet for the remainder of the corridor to the northeast end. The span of the subject property from the west end to the northeast end along the Singleton Road ROW is roughly 0.5 mile.

Most of the subject property west or southwest of the asphalt-paved road for Calimesa Boulevard is vacant area associated with ROW for Calimesa Boulevard or I-10 Freeway.

This area includes mature trees and approximate 6-foot high metal chain-link fencing.

Along either side of the Calimesa Boulevard ROW, near or immediately south of and within 500 feet of the Singleton Road ROW are areas of remnant features associated with past agricultural and/or residential use, including mature trees, fencing, asphalt access roads or drives, apparent former utility-related and former support-related pipes, and concrete foundation slabs. The area to the west of Calimesa Boulevard ROW includes slope retaining structures up to approximately 4 feet high along/near the west side of the roadway, including wood, concrete, and metal wire, including chicken wire. This area also includes several concrete slabs, at least one of which appeared to be associated with a former residence.

South of the former agricultural and/or residential area along the west side of Calimesa Boulevard are around three dozen roughly 20-foot sections of cement-lined ductile iron 25 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2

pipe that is approximately 24 inches in diameter. This pipes are being stored in a staging area that included personal and work vehicle parking. This staging area is associated with a project in progress under YVWD to install a 24-inch recycled water line that was observed under construction towards the south end of the subject property along the east or northbound lane along Calimesa Boulevard. The heavy equipment in this construction area included dump trucks for sandy or base materials, excavators, a loader, and a street sweeper. Towards the south end of this staging area is a stockpile of soil materials that appear to have been there prior to the arrival of the YVWD recycled water line installation. This soil stockpile is estimated to be approximately 70 feet long (north-south), approximately 60 feet wide (east-west), and up to approximately 5 feet high. The volume of this soil stockpile is estimated to be approximately 390 cubic yards.

Approximately 160 feet east-northeast of the intersection at Calimesa Boulevard and Singleton Road, along/near the south side of Singleton Avenue, is a semicircular dirt area that is covered with gravel, base, sandy, and/or crushed asphalt concrete materials.

This semicircular area is bermed along the south side of Singleton Road to prevent vehicles from driving into it or parking there. Approximately 90 feet east-northeast of the semicircular area is an asphalt-paved drive into what appeared to be a single-family residential property, but is being used as a preschool/day care facility (“Stavness Early Learning” at 35275 Singleton Road), about three-quarters of which is located within the subject property boundary that cuts across the two buildings present.

Extending from the intersection at Calimesa Boulevard and Singleton Road, along the north and northwest side of Singleton Road, is an artificial drainage channel which is estimated to be from roughly 5 up to 10 feet deep. Sections of this channel are situated fully within, others are outside, and others encroach into the subject property. This artificial channel begins at a concrete outfall structure offsite but nearly coincident with the northeast end of the subject property. From this concrete structure is a partially earthen channel lined with concrete along the slope coming down from the northwest side of Singleton Road. This partial earthen channel extends to the southwest until it reaches the location coincident with the offsite YVWD Well 48 fenced compound where there is a concrete outfall structure and the channel becomes fully lined with concrete. A concrete bridge crosses this channel southwest of the YVWD Well 48 compound, associated with a dirt road lead north and past the YVWD well compound.

Approximately 280 feet north-northeast of the intersection at Calimesa Boulevard and Singleton Road, among the lower elevations of the hilly topography at the subject property in relative close proximity to that intersection, is an approximate 1-foot steel pipe or casing 26 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
sticking up roughly 5 feet high with a rectangular piece of steel with opening attached to the top of it. At ground level next to this 1-foot steel pipe appears to be another steel pipe or casing or possibly a steel pail approximately 11 inches in diameter and filled with soil.

This location appears to coincide with a groundwater well indicated in historical topographic map images spanning from 1967 to 1996.

Along the summit/ridge line in the hilly area of the subject property northeast, north, and northwest of the intersection at Calimesa Boulevard and Singleton Road is a dirt road which winds down northerly slopes down to the location of Monty’s Montessori Preschool which partially encroaches into the subject property. The portion of this preschool situated within the subject property includes outdoor children’s exercise or play equipment, a canopy structure, and two classroom buildings that appear to be modular. Also within the subject property is parking lot and drive areas, including the main entrance into the preschool off of Calimesa Boulevard.

Towards the far northwest end of the subject property and within along the easterly boundary is a wooden fence line and dirt entrance drive associated with one or more rural residential and/or agricultural properties which appear to include a storage or staging area associated with the YVWD recycled water construction ongoing towards the south end of the subject property along Calimesa Boulevard. Next to the dirt entrance drive is an approximate 40-foot section of earthen drainage channel up to roughly 4 feet deep that terminates into a storm drain receiving structure that conveys drainage water underground near the dirt entrance drive.

Various utilities are present within the subject property, including electric, water (including for fire suppression), recycled water, sewer, storm drain, natural gas, cable television, and telecommunications. Pole-mounted electrical transformers were observed on several utility poles with no signs of transformer oil leakage. A pad-mounted electrical transformer is situated onsite at the location of Monty’s Montessori Preschool. No signs of transformer oil leakage was observed; however, a slope of soil from the adjacent hillside extends to the back (south) side of the transformer and engulfs the base of the transformer, obscuring places where leakage may be evident.

Relatively minor amounts of trash and debris, both dumped and windblown, are present at the subject property, including metal, wood, concrete, asphalt, glass, paper, household trash and debris, and tires. A small piece of asbestos-cement pipe was noted in the former residential area south of Singleton Road and west of Calimesa Boulevard. 27 LOR GEOTECHNICAL GROUP, INC.

The only container observed with hazardous materials or wastes is a plastic 5-gallon bucket with residual hydraulic oil in the bottom. This 5-gallon bucket is located along the east side of Calimesa Boulevard near a remnant line of trees and fencing approximately 460 feet south-southeast of the intersection at Calimesa Boulevard and Singleton Road.

Near this bucket appears to be surficial soil staining from some type of oil within an area approximately 4 feet wide by 25 feet long. This staining appears to be a trail leading out to Calimesa Boulevard, partially extending into the asphalt-paved road, and may have come from leaking heavy equipment.

Other locations were noted with heavy petroleum (oil-range) hydrocarbon-stained soils, including two areas located near a utility pole approximately 185 feet south-southeast of the northwest end of the subject property along Calimesa Boulevard. These areas of stained soils are estimated to be approximately 1 foot wide by 3 feet long and approximately 3 feet wide by 10 feet long.

No evidence of the following were observed at the subject property, except as may have been mentioned above: petroleum products, solvent degreasers, aboveground storage tanks, underground storage tanks, heating oil use, drums, unidentified containers with hazardous substances/petroleum products, pools of liquid likely to contain hazardous substances/petroleum products, polychlorinated biphenyls (PCBs), stressed vegetation, fill areas with solid waste, sumps, pits/ponds/lagoons, wells, and stormwater and/or wastewater generated from industrial/manufacturing processes. No strong, pungent, or noxious odors were detected.

9.1 Adjoining Properties
Outside the subject property are extensions of the roadways which cross through the subject property. These roadways include Calimesa Boulevard, which extends outside the subject property to the north-northwest and southeast, and Singleton Road, which extends outside the subject property to the west and northeast. A third roadway, Beckwith Avenue, intersects near the middle of Singleton Road within the subject property, extending outside the subject property to the southeast.

Much of the surrounding properties are vacant land or scattered rural residences and associated structures. On a couple of these residential properties are cellular communications towers and associated equipment, the closest of which is located approximately 150 feet north of the far northwest end of the subject property along Calimesa Boulevard. Over 50 feet to the north of the far northeast end of the subject 28 LOR GEOTECHNICAL GROUP, INC.

property along Singleton Road, is a tract of single-family residences beginning at the top of an approximate 30-foot slope.

Encroaching into the subject property, and located adjacent to the north, northeast, and east is a Monty’s Montessori Preschool at 9580 Calimesa Boulevard.

Adjacent to the west/southwest of most of the subject property is Caltrans right-of-way associated with the I-10 Freeway, including for the above-mentioned westbound off-ramp.

Adjacent to the southeast of the easterly rough half of Singleton Road is Sharondale, a senior community that includes numerous mobile homes and open park areas.

West-southwest of the Sharondale senior community and across Beckwith Avenue is a preschool/day care facility (“Stavness Early Learning” at 35275 Singleton Road) which extends from the subject property to offsite generally to the south.

YVWD Well 48 is located near the northerly side of the subject property within a fenced compound at 35290 Singleton Road, on the other side of a concrete-lined drainage channel and roughly 700 feet east-northeast of the intersection at Calimesa Boulevard and Singleton Road. Near this municipal well site is a horse ranch (includes other animals) and event venue (Fascination Ranch) which may include a single-family residence on property adjacent to the fenced compound for Well 48. This horse ranch, with main address at 35600 Singleton Road, is situated on property that extends near or all the way to the northwest side of the subject property along Singleton Road, including a dirt drive entrance across a concrete bridge.

Color photographs of the subject property and adjoining properties, documenting the subject property reconnaissance, are presented in Appendix F.

10.0 ENVIRONMENTAL REGULATORY AGENCY RECORDS REVIEW
Due to the numerous properties within or adjoining the subject property, and no sites at or adjoining the subject property identified with significant activities warranting such a request, records requests to environmental regulatory agencies were not made. However, online research of environmental regulatory agency records was conducted, including for the California Regional Water Quality Control Board - Santa Ana Region (CRWQCB-SAR), California Department of Toxic Substances Control (DTSC), and South Coast Air Quality Management District (SCAQMD).

10.1 California Regional Water Quality Control Board - Santa Ana Region The California State Water Resources Control Board (SWRCB) maintains the online GeoTracker database, which includes the following CRWQCB-SAR and other agency records: 1) cleanup sites, including leaking underground storage tank (LUST) sites, cleanup program sites, military cleanup sites, and California Department of Toxic Substances Control (DTSC) cleanup sites; 2) permitted facilities, including waste discharge requirements sites, permitted USTs, DTSC hazardous waste sites, land disposal sites, irrigated lands regulatory program sites, and oil/gas sites; and 3) other sites, including project sites, non-case information sites, sampling points - public, and field points.

This database was searched for records that may pertain to the subject property and adjoining properties (California State Water Resources Control Board, 2022).

No sites were found at the subject property. The closest listed site is a DTSC school investigation site, Summerwind K-8 Project, located roughly 0.5 mile to the south-southeast of the subject property. The GeoTracker website links to the DTSC ENVIROSTOR online database, which indicates this school investigation site is a 20.9-acre property of former grazing land and no potential soil contaminants were found. This site is shown with a “No Further Action” status as of October 4, 2018.

Verizon Wireless Calimesa Relo, located at 35600 Singleton Road, a horse ranch and event venue (“Fascination Ranch”) situated on property that extends to Singleton Road adjacent to the northwest of the subject property, is shown with an active status, a diesel-powered emergency backup electric generator, and no Notices to Comply or Notices of Violation.

11.0 ENVIRONMENTAL DATABASE REVIEW
EDR was contacted to provide an environmental database search for the subject property (“target property” in EDR’s database report). The database search provides information regarding landfills, USTs, hazardous waste generators, etc., at the subject property and surrounding properties in accordance with ASTM Standards and AAI.

Five sites, not including the subject property, were found in EDR’s search of available government records within the respective search radii. A copy of the EDR database report, which provides a complete list of the federal, state, tribal, and proprietary records searched, is provided in Appendix G.

11.1 ENVIROSTOR
The California DTSC Site Mitigation and Brownfields Reuse Program’s ENVIROSTOR database identifies sites that have known contamination or sites for which there may be reasons to investigate further. There is one site, Summerwind K-8 Project at Roberts Road and Cherry Valley Boulevard (now Tukwet Canyon Parkway), previously discussed under subsection 9.1 of this Phase I ESA report. This school investigation site has a “No Further Action” status under DTSC, and has been developed as a school (elementary and middle school).

11.2 RCRA NonGen/NLR
RCRAInfo is EPA’s comprehensive information system that includes selective information on sites which generate, transport, store, treat, and/or dispose of hazardous waste as defined by RCRA (Resource Conservation and Recovery Act). Non-Generators do not presently generate hazardous waste. One site, QR Birtcher Oak Valley Owner, LLC at 31 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
35010 Singleton Road, located approximately 0.1 mile west of the subject property, is listed in this database with no reported violations.

11.3 FINDS
The Facility Index System (FINDS), maintained by the USEPA, contains both facility information and ‘pointers’ to other sources that contain more detail. Two sites are listed in the FINDS database, indicated to be immediately adjacent to the subject property.

The first listed FINDS site, Sprint United Management Co. at 9530 Calimesa Boulevard, is likely associated with a cellular communications tower and associated equipment located approximately 510 feet east-northeast of the subject property. This telecommunications site has FINDS information indicating it is under a Risk Management Plan (RMP), likely for lead-acid batteries, and possibly, for diesel fuel (emergency backup electric generator).

The second listed FINDS site, Well 48, has an associated building addressed 35290 Singleton Road, estimated to be approximately 20 feet northwest of the subject property, with other structures generally located farther away, with the exception of a pad-mounted electrical transformer. The FINDS information for Well 48 indicates the site is an Emergency Planning and Community Right-to-Know Act (EPCRA) facility under an RMP, possibly due to water treatment chemicals (such as chlorine) and diesel fuel (emergency backup electric generator) present.

EDR Site Reports™ with links to FINDS database information are provided within Appendix G.

11.4 Notify 65
Listings of all Proposition 65 incidents reported to counties by the SWRCB and the Regional Water Quality Control Board. This database is no longer updated. One site, ARCO Calimesa #1958 at 1216 Calimesa Boulevard, over 0.8 mile north-northwest of the subject property, is listed in this database with no pertinent information shown other than the site name and address. However, this site is listed in other databases, including with closed LUST regulatory cases in June 1989 and August 2008.

11.5 CERS
The California EPA Regulated Site (CERS) Portal database combines data about environmentally regulated sites and facilities in California into a single database.

It combines data from a variety of state and federal databases, and provides an overview 32 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
of regulated activities across the spectrum of environmental programs for any given location in California. These activities include hazardous materials and waste, state and federal cleanups, impacted ground and surface waters, and toxic materials. One site, Well 48 at 35920 Singleton Road, indicated to be adjacent to the subject property, is listed in the CERS database as a chemical storage facility. No violations were reported during compliance evaluation inspections by County of Riverside Department of Environmental Health personnel in June 2016 and July 2019. The owner of the well site is indicated to be Yucaipa Valley Water District.

11.6 Orphan Summary
The Orphan Summary within the EDR database report, which is a list of all sites whose location is not readily identified (mapped), and may be at or near the subject property, was reviewed. The subject property and adjoining properties are not listed in the Orphan Summary.

11.7 Other Databases
California Geologic Energy Management Division
The California Geologic Energy Management Division (CalGEM) maintains a list of all producing and abandoned oil and gas wells within the State of California. We reviewed the online CalGEM Well Finder, which indicates no abandoned or producing gas and/or oil wells have been located within 1 mile of the subject property (CalGEM, 2022).

12.0 VAPOR ENCROACHMENT EVALUATION
As part of this Phase I ESA, a Vapor Encroachment Screen (VES) was conducted to determine if a vapor encroachment condition exists, based on the information obtained during the Phase I ESA. A Vapor Encroachment Condition (VEC) is the presence or likely presence of chemicals of concern (COC) vapors in the subsurface of the target property caused by the release of vapors from contaminated soil or groundwater either on or near the target property (i.e., subject property).

12.1 Vapor Encroachment Screen
A VES, comprised of Tier 1 screening, was conducted by this firm for the subject property. The VES was conducted in general accordance with the Standard Guide for 33 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
Vapor Encroachment Screening on Property Involved in Real Estate Transactions, ASTM E2600-15. Although not required to satisfy the requirements of the Phase I ESA under ASTM E1527-13 and E1527-21, ASTM E2600-15 was chosen as a methodology to evaluate potential contaminant vapor concerns at or adjoining the subject property.

It should also be noted that any potential VECs identified will likely have little, if any, impact to the proposed development of the subject property, as no enclosed, occupied structures are proposed. Confined space conditions, such as trenches or other excavations where sufficient air mixing is not present may be impacted by any potential VECs identified.

The historical usage of the subject property and adjoining properties includes vacant land, residential, agricultural usage (mostly dryland farming and a horse ranch with smaller areas including grove or irrigated farming), public roadways, groundwater production well sites (including a municipal agency facility), a day care/preschool facility, a preschool, and cellular communications towers and associated equipment. The subject property and surrounding area are anticipated to be underlain by interbedded sands, silts, and clays with varying amounts of gravel. Based on the local geology and hydrogeology, the groundwater beneath the subject property, estimated to be present at depths greater than 100 feet bgs, is not considered to be a likely source of vapor into the subject property.

Based on the results of Tier 1 screening per ASTM E2600-15, utilizing the EDR Radius Map™ Report with GeoCheck®, there are no sites within 0.33 mile with current and/or former potential sources of soil vapor intrusion or encroachment. Based on the results of the VES, Tier 1 screening, a VEC at the subject property can be ruled out.

13.0 FINDINGS
The use of the subject property has historically and recently, dating back to the early 1900s, includes vacant land, dirt and paved roadways (including along street and freeway ROWs), residential structures, a groundwater well, a natural drainage feature that was artificially channeled, farmland (predominantly dryland), and buildings and canopy associated with a preschool campus.

Areas of oil-stained soils, which are anticipated to be surficial (within the upper foot of soil), were observed along or near the sides of the asphalt-paved road along Calimesa Boulevard. At one of these areas of stained soils, along the easterly side of Calimesa Boulevard and approximately 450 feet south-southeast of the intersection at Calimesa Boulevard and Singleton Road, a 5-gallon plastic bucket, labeled as containing hydraulic 34 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2

oil, has a residual amount of liquid in the bottom. No other containers with hazardous materials or wastes was observed at the subject property.

There are five sites, not including the subject property, listed in environmental regulatory databases within 1 mile of the subject property. Based on our research and VES, no environmentally impaired properties have current or former releases of hazardous substances and/or petroleum products that are known to have migrated to and/or impacted the subject property, and therefore, a VEC can be ruled out for the subject property.

13.1 Data Gaps
Under AAI and ASTM E1527-13 and E1527-21, data gaps that remain after the conduct of all required activities must be identified. The source of information consulted to address the data gaps should be identified, and the significance of the data gaps with respect to our ability to identify conditions indicative of releases or threatened release of hazardous substances on, at, in, or to the property should be addressed.

Due to the size and nature of the subject property, property owner interviews were not conducted, nor were regulatory agency records requested. However, based on historical topographic maps and aerial photograph images, environmental database report, and online environmental regulatory agency records reviewed, it does not appear these data gaps are significant enough to impact the findings, opinions, and conclusions of this Phase I ESA.

14.0 OPINIONS
The oil-stained soils observed at the subject property are anticipated to be limited in vertical extent, and are deemed to be a de minimis condition.

The limited (both in area and time) irrigated farming use of the subject property is not anticipated to have an adverse environmental impact.

The historical use of the subject property or nearby properties for current or historical roadways, including the past US Routes 70 and 99 and current I-10 Freeway, has likely impacted soils at the subject property with ADL. The most significant ADL impacts are anticipated along the west/southwest end of the subject property. 35 LOR GEOTECHNICAL GROUP, INC.

TKE Engineering, Inc. Project No. 63686.2
September 26, 2022
The approximate 390 cubic yard soil stockpile along the west side of Calimesa Boulevard towards the south end of the subject property appears to be undocumented as to how it was generated and came to be where it is. This soil stockpile may have been generated during the planting of trees in the two areas of the subject property along the westerly side of Calimesa Boulevard, or perhaps some other roadway project. Aside from possible ADL impacts, we do not anticipate the soil stockpile will have an adverse environmental impact.

15.0 CONCLUSIONS
We have performed a Phase I ESA in conformance with the scope and limitations of ASTM E1527-13 and E1527-21, and AAI, of the subject property. This assessment has revealed no RECs, CRECs, or significant data gaps in connection with the subject property.

The limited past irrigated farming use of the subject property, ADL, and approximate 390 cubic yard soil stockpile are environmental concerns which can be addressed by soil sampling and analysis.

16.0 ADDITIONAL INVESTIGATION
The only way to confirm our opinion regarding the potential impact to soils at the subject property from past agricultural irrigated farming, historical use of leaded gasoline in vehicles traveling within or near the subject property (ADL), and the approximate 390 cubic yard soil stockpile along the west side of Calimesa Boulevard towards the south end of the subject property, would be to perform soil sampling and subsequent laboratory analysis and data evaluation.

17.0 STATEMENT OF QUALIFICATIONS
We have the specific qualifications based on education, training, and experience to assess a property of the nature, history, and setting of the subject property. We have developed and performed the all appropriate inquires in conformance with the standards and practices set forth in 40 CFR Part 312.

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.

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 04/25/2022 has revealed that there is 1 ENVIROSTOR site within approximately 1 mile of the target property.

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
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 Site Mitigation and Brownfields Reuse Program (SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed restrictions that are active. Some sites have multiple deed restrictions. 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.

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.

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.

HIST FTTS: FIFRA/TSCA Tracking System Administrative Case Listing A complete administrative case listing from the FIFRA/TSCA Tracking System (FTTS) for all ten EPA regions. The information was obtained from the National Compliance Database (NCDB). NCDB supports the implementation of FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) and TSCA (Toxic Substances Control Act). Some EPA regions are now closing out records. Because of that, and the fact that some EPA regions are not providing EPA Headquarters with updated records, it was decided to create a HIST FTTS database. It included records that may not be included in the newer FTTS database updates. This database is no longer updated.

UMTRA: Uranium Mill Tailings Sites
Uranium ore was mined by private companies for federal government use in national defense programs. When the mills shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings were used as construction materials before the potential health hazards of the tailings were recognized.

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.
