MANAGEMENT SUMMARY
The Belago Park Project (hereafter referred to as Project or Project Area) proposes the construction of a residential development consisting of detached single-family homes (Project). The proposed Project consists of 15 parcels totaling approximately 45-acres, which are located at the intersection of Cactus Avenue and Redlands Boulevard in the City of Moreno Valley, Riverside County, California. Material Culture Consulting, Inc. (MCC) was retained by E|P|D Solutions, Inc. to conduct a Phase I paleontological resource investigation of the Project Area. This assessment was conducted in accordance with the California Environmental Quality Act (CEQA) and included fossil locality searches, an examination of geologic maps and paleontological literature, and a field survey.

Based on geologic mapping, the Project Area is mapped as surficial younger Quaternary alluvium with older Quaternary alluvium at unknown depths. No significant paleontological resources were identified directly within the Project Area during the locality searches or the field survey. The locality searches conducted by the Natural History Museum of Los Angeles County (LACM) and Western Science Center (WSC) did yield nearby localities from sedimentary deposits similar to those that may occur subsurface in the Project Area. A literature search indicated that significant fossil resources were recovered from construction activities approximately 1.5 miles northeast of the Project. The Riverside County Land Information System (RCLIS) GIS data revealed that the entirety of the Project Area lies within an area mapped as High B sensitivity. A designation of High B sensitivity indicates that these sedimentary rock units have high potential for containing significant non-renewable paleontological resources at depths at or below 5 feet. Excavation during the course of the Project may reach paleontologically sensitive deposits, and, as a result, could impact paleontological resources. Therefore, MCC recommends the following procedures:
• A trained and qualified paleontological monitor should perform full-time monitoring of any excavations within the Project Area that have the potential to impact paleontological resources in undisturbed High B sensitivity native sediments, at or below 5 feet in depth. The monitor will have the ability to redirect construction activities to ensure avoidance of adverse impacts to paleontological resources. • The project paleontologist may re-evaluate the necessity for paleontological monitoring after examination of the affected sediments during excavation, with approval from County and Client representatives. • Any potentially significant fossils observed shall be collected and recorded in conjunction with best management practices and Society of Vertebrate Paleontology (SVP) professional standards. • Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations. • A report documenting the results of the monitoring, including any salvage activities and the significance of any fossils, will be prepared and submitted to the appropriate County personnel.

INTRODUCTION
The Belago Park Project (hereafter referred to as Project or Project Area) proposes the construction of a residential development consisting of detached single-family homes within the City of Moreno Valley in Riverside County, California. Material Culture Consulting, Inc. (MCC) was retained by E|P|D Solutions, Inc. to conduct a Phase I paleontological resource investigation of the Project Area. This paleontological resource assessment was conducted in compliance with the California Environmental Quality Act (CEQA), Public Resources Code (13 PRC) 2100, (14 CAC) 15000, Appendix G, Section J, (PRC) 2100-21177, Appendix G, (PRC) 5097.5 and guidelines in accordance with Society of Vertebrate Paleontology (2010) standards. According to these regulations and guidelines, if development of a Project has the potential to result in significant impacts to paleontological resources, a plan must be developed to mitigate those impacts to a level which is less than significant. This assessment documents the potential for encountering paleontological resources during development of this Project and provides recommendations on how to mitigate impacts to those resources. This assessment included fossil locality records searches, an examination of geologic maps and paleontological literature, and a pedestrian field survey.

PROJECT LOCATION AND DESCRIPTION
The Project is located in the City of Moreno Valley, located within northwestern Riverside County (Figure 1). The Project consists of 15 undeveloped parcels totaling approximately 45-acres (APNs 478-100-012, 478-100-035 478- 100-001, 478-120-001, 478-120 -002, 478-120-005, 478-120-006, 478-110-002, 478-120-025, 478-110-007, 478- 110-003, 478-110-004, 478-110-005, 478-110-006, and 478-120-027) located at the northeast corner of Cactus Avenue and Redlands Boulevard in the City of Moreno Valley, Riverside County, California (Figures 2 and 3). The Project is bounded by residential housing on Brodiaea Avenue to the north and on Cactus Avenue to the south.

Undeveloped areas are present east of Redlands Boulevard and west of Wilmont St. The area currently exists as a vacant area with some mowing and off-roading disturbance. A paved pipeline runs southwest to northeast through the Project Area. The Project Area may be found on the Sunnymead USGS 7.5-minute topographic quadrangle in Section 14 of Township 3 South, Range 3 West, San Bernardino Base Meridian (Figure 2).

PROJECT PERSONNEL
Jennifer Kelly, M.S., a Qualified Riverside County Paleontologist, served as the Principal Investigator for the study.

Ms. Kelly conducted the paleontological resource literature and map reviews, oversaw the field study, and prepared this report. Ms. Kelly has a M.Sc. in Geology from California State University, Long Beach. Ms. Kelly has over 12 years of experience in environmental and paleontological compliance in California (See Appendix A). Erika McMullin, B.A., MCC archaeologist and cross-trained paleontologist, co-authored this report and conducted the pedestrian survey.

ENVIRONMENTAL SETTING
The Project Area is located within the City of Moreno Valley in northwestern Riverside County, approximately

0.28-mile northwest of Mount Russell. Bounded by the Box Springs Mountains to the north, the Badlands to the east, and Lake Perris Recreation Area and associated mountains to the south, the Project Area is located within a relatively flat valley floor that is surrounded by hills and mountains. Elevations are approximately 481 meters (m) (1580 feet) above mean sea level (AMSL) throughout the Project Area. The region is located within the Peninsular Ranges, a northwest-southeast oriented complex of blocks separated by similarly trending faults (Norris and Webb 1978). Most geological formations found within this area are part of the Southern California Batholith complex, a great mass of igneous basement rocks. Vegetation observed throughout the entirety of the Project Area included grasses and weeds. A few non-native eucalyptus trees were present on the eastern border of the Project Area.

Tumbleweeds and native shrubs were observed in the western portion. The climate in the region is characterized as Mediterranean, with hot, dry summers and temperate, wet winters.

GEOLOGICAL CONTEXT
The Project Area lies within the Sunnymead quadrangle, which lies within the geomorphic province known as the Peninsular Ranges Province, sitting near the eastern margin of the Perris Block (Kenney 1999). The Perris Block is a structurally stable, internally cohesive mass of crustal rocks bounded on the east by the San Jacinto fault zone, bounded on the west by the Elsinore and Chino fault zones, on the north by the Cucamonga fault zone (Norris and Webb 1976; Morton and Matti 1989), and on the south by a series of sedimentary basins (Morton and Matti 1989).

The Project area is mapped as young alluvium fan deposits transported and deposited in channels, washes, and on alluvial fan surfaces. Additional literature maps the northeastern portion of the Project Area within surficial Quaternary alluvial fan deposits and very old alluvial fan deposits in the southeastern corner of the Project Area (Figure 4) (Morton and Matti 2001). Furthermore, the WSC has mapped the furthest eastern corner, near the intersection of Cactus Avenue and Redlands Boulevard, as Mesozoic granite rocks (grMz) and the rest of the Project Area as Quaternary alluvium (Q) dating to the Pliocene-Holocene (McDonald 2021). While grMz does not have the potential to yield fossils, Quaternary alluvial units have the high potential to yield significant fossil resources (McDonald 2021).

Mesozoic granite rocks (grMZ) are fine-grained to coarse-grained granitic dikes and plutonic rocks, composed of granodiorite, tonalite, quartz monzonite, and granite. These units are not suitable for the preservation of fossil resources and have low to no sensitivity.

Very old alluvial fan deposits (Qvof) are early Pleistocene deposits consisting of mostly well-dissected, wellindurated, reddish-brown sand deposits with minor gravel (Morton and Matti 2001). These deposits are commonly flanking bedrock areas and can contain duripans and locally silcretes (Morton and Matti 2001). These sediments are derived as alluvial fan deposits from the elevated terrain located immediately to the south of the Project Area.

The surficial sediments can be relatively coarse and lack significant vertebrate fossils in the uppermost layers, but may have pockets of finer-grained Quaternary deposits that contain significant vertebrate fossils at depth. Fossils found within Pleistocene-aged terrestrial deposits in this area may include mammoth, mastodon, camel, horse, llama, and other, smaller vertebrate and invertebrate remains. This unit has moderate to high (High B) paleontological sensitivity.

Young alluvial fan deposits (Qyf) are Holocene and late Pleistocene sediments derived from lithicly diverse sedimentary units (Morton and Matti 2001). These units are gray-hued sand and cobble- and gravel-sand deposits.

These units are unlikely to produce significant paleontological resources surficially, unless Pleistocene-aged deposits are encountered. These units have a low to moderate paleontological sensitivity.

RESEARCH DESIGN
Paleontological resources (fossils) are the remains of prehistoric life that provide an invaluable window into the past. These remains can be bones, teeth, shells, wood or leaves, or trace fossils (including burrows and trackways).

The Society for Vertebrate Paleontology (SVP) generally considers any resource greater than 5,000 years old to be a fossil (SVP 2010). Fossils are considered non-renewable resources and in California, impacts to paleontological resources must be considered pursuant to CEQA requirements for environmental reviews.

The paleontological resources assessment was conducted according to CEQA, Public Resources Code (13 PRC) 2100, (14 CAC) 15000, Appendix G, Section J, (PRC) 2100-21177, Appendix G, (PRC) 5097.5. The paleontological resources assessment was conducted to evaluate the potential existence of resources that would require a preparation of a monitoring plan and monitoring activities, in order to reduce impacts to a less than significant level.

The Moreno Valley General Plan’s (2006) Conservation Element Programs 7-6 states “in areas where archaeological or paleontological resources are known or reasonably expected to exist, based upon the citywide survey conducted by the UCR Archaeological Research Unit, incorporate the recommendations and determinations of that report to reduce potential impacts to levels of insignificance”. Additionally, the Environmental Impact Report for City of Moreno Valley General Plan (P&D Consultants 2006) has one mitigation measure concerning paleontological resources:
• C1. Prior to the approval of a project, the City will assess potential impacts to significant historic, prehistoric archeological, and paleontological resources, including impacts to human remains, pursuant to Section 15064.5 of the California Environmental Quality Act Guidelines. If significant impacts are identified, the City will require the project to be modified to avoid the impacts, or require measures to mitigate the impacts. Mitigation may involve monitoring, resource recovery, documentation or other measures.

METHODS

LITERATURE AND MAP REVIEW AND LOCALITY SEARCH
The literature review included an examination of geologic maps of the Project Area and a review of relevant geological and paleontological literature, including published peer-reviewed documents and previous research on the area, to determine which geologic units are present within the Project Area and whether fossils have been recovered from those geologic units elsewhere in the region. As geologic units may extend over large geographic areas and contain similar lithologies and fossils, the literature review includes areas well beyond the Project Area.

The results of this literature review include an overview of the geology of the Project Area and a discussion of the paleontological sensitivity (or potential) of the geologic units within the Project Area. Riverside County Land Information System (RCLIS), which provides a paleontological resource sensitivity map for the entire county, was consulted by MCC staff on February 4, 2021. Additional sources reviewed included the University of California Museum of Paleontology (UCMP) Miocene Mammal Mapping Project (MioMap) and the Paleobiology Database (PBDB). Previous local construction-related reports were also consulted to determine if fossils were recorded from other projects nearby.

The purpose of a locality search is to establish the status and extent of previously recorded paleontological resources within and adjacent to the study area for a given project. On December 31, 2020, a locality search was conducted through the LACM in Los Angeles (Appendix B). This search identified any vertebrate localities in the LACM records that exist near the Project Area in the same or similar deposits. Additionally, on June 4, 2021, a locality search was conducted through WSC in Hemet, California. The search identified the geological units underlying the Project Area and any fossil localities in the WSC records that exist near the Project Area or any localities within similarly mapped sediments throughout the region (Appendix B).

PALEONTOLOGICAL RESOURCES SURVEY METHODS
The survey stage is important in a Project’s environmental assessment phase to verify the exact location of each identified paleontological resource (if any), the condition or integrity of the resource, and provides invaluable information on the type of sediment present within the Project Area, which informs the assessment of paleontological sensitivity. On February 15, 2021, MCC qualified archaeologist and cross-trained paleontologist Erika McMullin conducted a pedestrian survey of the Project Area. Special attention was paid to any graded areas and to rodent burrows that offered a better view of the underlying sediment. The purpose of a field survey is to note the sediments in the Project Area, relocate any known paleontological localities, and identify any unrecorded paleontological resources exposed on the surface. In this way, impacts to existing, unrecorded paleontological material may be mitigated prior to the beginning of ground-disturbing activities, and portions of the Project Area that are more likely to contain paleontological resources may be identified.

RESULTS

MUSEUM LOCALITY SEARCH AND LITERATURE REVIEW RESULTS
The record search results from the LACM (Bell 2020, Appendix B) did not indicate any previously identified fossils directly within the Project Area; however, there are known localities nearby from the same sedimentary deposits mapped within the Project Area (see Table 1). The closest vertebrate fossil locality from similar deposits is LACM VP 6059, from an unknown formation, located near Lake Elsinore, located approximately 18 miles southwest of the Project Area. This locality produced a fossil specimen of camel (Camelidae) at unknown depth (Bell 2020).

Additionally, the record search results from the WSC (McDonald 2021) also concluded that no localities have been identified within 1-mile of the Project Area. However, numerous fossil resources from similarly mapped Pleistocene alluvial sediments have been identified throughout the region. Examples of fossils from these Pleistocene alluvial deposits includes Columbian mammoth (Mammuthus columbi), Pacific mastodon (Mammut pacificus), sabertooth cat (Smilodon fatalis ancient horse (Equus sp.), and many other Pleistocene megafauna (McDonald 2021). However, public documents containing previous records searches for the area indicate that significant Pleistocene-aged fossils were recovered from the construction of an Aldi logistics site approximately 1.5 miles northeast of the Project, near the intersection of Redlands Boulevard and Eucalyptus Avenue Fossils from these localities were recovered from 11 to 13 feet below ground surface in an area mapped as Holocene and late Pleistocene young alluvial fan deposits (Morton and Matti 2001). Reported fossils from this locality include ground sloth (Megalonyx jeffersonii), lamine camel (Hemiauchenia sp.), and horse (Equus sp.) (Rincon 2019).

The Paleobiology Database (PBDB) yielded no results within the region. The MioMap yielded eight fossil assemblage localities from the San Timoteo formation located within 5 miles of the Project Area (Appendix B). The closest fossil assemblage is mapped approximately 4.5 miles northeast of the Project Area within San Timoteo Canyon, which contained fossil specimen of mammoth (Mammuthus imperator) (Carrasco et al. 2005). All eight of the fossil assemblages are within a 5 mile radius of one another.

PALEONTOLOGICAL FIELD SURVEY RESULTS
During the course of fieldwork, survey conditions were fair, and visibility ranged greatly within the Project Area.

The eastern portion, east of Wilmont St., had been recently plowed as evident by the loose soil and furrows. The portion located west of Wilmont St. had been graded, but not as recently as the eastern portion, as observed in the absence of soil furrows, more compacted soil, and denser vegetation. Due to recent rain, seasonal grasses and weeds covered most of the ground surface. While soil was visible in some areas, the overall visibility was poor (5- 15%). Due to the dense grass covering, 5-meter transects where walked to compensate for the poor visibility. A creek runs southwest to northeast. The creek has been modified during the construction of Cactus Avenue and Redlands Boulevard as evident by the graded slopes and concrete road bridges. Furthermore, the entire area shows heavy disturbance from grading activities.

On the eastern portion of the Project Area, the surface floor is roughly 10-15 feet below Redlands Avenue A large berm platform formed by prior construction activities was observed west of the creek and east of Wilmont St.

Other disturbances created by construction activities include a small mound and a circular ditch. The small mound was observed in the southwestern of the Project Area. The mound appeared unnatural, most likely an old push pile, with remnants of soil, concrete, and imported landscaping rocks. There was evidence of modern dumping surrounding the mound. In addition, a ditch was observed in the eastern portion of area, south of the creek. The ditch was a complete circle and measured approximately 7 feet in diameter, with a depth of 3 feet. The ditch appeared to be machine made, likely occurring during the grading of the area and recent construction of the residential housing tract west of the Project Area.

Soil observed was consistent with the mapped Quaternary sediments, with pebble to large cobble-sized rocks of granite, and pebble- to small cobble-sized pieces of quartz. Imported/dumped piles of landscaping rocks were observed along the southern-most border near Cactus Avenue, and near the northernmost border near Brodiaea Avenue. Other disturbances to the area include modern refuse and bioturbation (ant hills and animal burrows). No paleontological resources were observed during the field survey. Representative photographs of the Project Area are found in Figures 6-25.

SUMMARY AND RECOMMENDATIONS
MCC conducted a Phase I paleontological resource assessment of the Project Area that included fossil locality records searches, literature reviews, and an intensive pedestrian survey covering the majority of the 40-acres. No significant paleontological resources were identified within the Project Area during the locality records searches or field survey. However, there are nearby fossil localities that have produced significant paleontological resources within sedimentary deposits that are also mapped within the Project Area. The uppermost layers of soil within the Project Area consist of younger alluvial deposits that may shallowly overlie older, more paleontologically sensitive sediments. In addition, the Project Area is mapped in RCLIS as High Sensitivity B, which is based on the presence of geologic formations or mapped rock units that are known to contain (or have the correct age and depositional conditions to contain) significant paleontological resources at depths below 5 feet.

RECOMMENDED MITIGATION
Based on the results of the Phase I paleontological resource assessment, the proposed Area is considered to have moderate-to-high sensitivity for the potential to impact paleontological resources during ground-disturbing construction activities in undisturbed sedimentary deposits. MCC recommends preparation of a Paleontological Resource Management Plan (PRMP) prior to construction excavation, in order to mitigate any potential impact to non-renewable fossil resources to a less-than-significant level. It is recommended that a professional paleontologist be hired to oversee monitoring and the preparation of a PRMP. At a minimum, the PRMP should include the following items:
• A trained and qualified paleontological monitor should perform full-time monitoring of any excavations on the Project that have undisturbed native sediments below 4 feet in depth. The monitor will have the ability to redirect construction activities to ensure avoidance of adverse impacts to paleontological resources.
• The Project paleontologist may re-evaluate the necessity for paleontological monitoring after examination of the affected sediments during excavation, with approval from County and Client representatives. • Any potentially significant fossils observed shall be collected and recorded in conjunction with best management practices and SVP professional standards.
• Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations. • A report documenting the results of the monitoring, including any salvage activities and the significance of any fossils, will be prepared and submitted to the appropriate County personnel.

Material Culture Consulting, Inc. | 2701-B North Towne Avenue Pomona CA 91767 | 626-205-8279 | www.materialcultureconsulting.com (2012-2013). Ms. Kelly conducted all research and data collection for the Cadiz Groundwater Conservation and Storage Project for completion of a DEIR section on paleontological resources. Based on the results of the analysis, Kelly prepared the mitigation measures which were designed to reduce potential adverse impacts to paleontological resources.

Paleontological Project Manager, Manzana Wind Express Project, Kern County, California (2012-2015).

Ms. Kelly prepared the Paleontological Mitigation Monitoring Resource Plan, which allowed her to develop a key role in presenting environmental training programs to construction workers and other environmental compliance monitors. She also authored the final paleontological monitoring report. The Project’s construction consisted of the installation more than 300 wind energy turbines, aligned along approximately 26 rows, on the 6,275-acre proposed site. The Manzana Wind Energy Project site was found to have the potential for scientifically significant paleontological resources that could be impacted by construction-related ground disturbance.

I have conducted a thorough search of our paleontology collection records for the locality and specimen data for proposed development at the Cactus Moreno Valley project area as outlined on the portion of the Sunnymead USGS topographic quadrangle map that you sent to me via e-mail on December 17, 2020.

We do not have any fossil localities that lie directly within the proposed project area, but we do have fossil localities nearby from the same sedimentary deposits that occur in the proposed project area, either at the surface or at depth.

Dear Ms. Belcourt,
This letter presents the results of a record search conducted for EPD Belago Park Moreno Valley Project, in the City of Moreno Valley, Riverside County, California. The project site is located in Section 14 of Township 3 South and Range 3 West on the Sunnymead USGS 7.5 minute topographic quadrangle.

The geologic units underlying the project area are mapped as Mesozoic granitic rocks, which have no fossil potential, and Quaternary alluvium dating to the Pliocene-Holocene. Quaternary alluvial units are considered to be of high paleontological sensitivity. The Western Science Center does not have localities within the project area, but does have numerous localities within similarly mapped alluvial sediments throughout the region. Pleistocene alluvial deposits in southern California are well documented and known to contain abundant fossil resources including those associated with Columbian mammoth (Mammuthus columbi), Pacific mastodon (Mammut pacificus), sabertooth cat (Smilodon fatalis), ancient horse (Equus sp.), and many other Pleistocene megafauna.

Any fossils recovered from the EPD Belago Park Moreno Valley Project area would be scientifically significant. Excavation activity associated with development of the area has the potential to impact the paleontologically sensitive Quaternary alluvial units and it is the recommendation of the Western Science Center that a paleontological resource mitigation plan be put in place to monitor, salvage, and curate any recovered fossils associated with the current study area.

If you have any questions, or would like further information, please feel free to contact me at [email protected]
Sincerely,
Andrew McDonald
