Chambers Group, Inc. ii 21128 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California SECTION 1.0 – INTRODUCTION

Chambers Group, Inc. (Chambers Group) has been contracted by Control Management, Inc., within the City of Jurupa Valley, Riverside County, California, to complete an Archaeological and Paleontological Literature Review and site survey for the proposed commercial development. The proposed project includes the construction of a convenience store, service station, car wash, commercial building, restaurant building and parking lot. The project is proposed on an existing 16.22-acre property located in on the southeast corner of Van Buren Blvd and Rutile Street, Jurupa Valley, Riverside County.

Chambers Group completed an Archaeological and Paleontological Literature Review and site survey of the 16.22-acre project location. This report outlines the Archaeological and Paleontological findings.

The following study has been conducted in accordance with the California Environmental Quality Act (CEQA). This report includes appropriate mitigation measures to ensure less than significant impacts to inadvertent findings of cultural resources during construction.

1.1 REGULATORY FRAMEWORK

Work for this project was conducted in compliance with CEQA. The regulatory framework as it pertains to cultural resources under CEQA has been detailed below.

Under the provisions of CEQA, including the CEQA Statutes (Public Resources Code [PRC] §§ 21083.2 and 21084.1), the CEQA Guidelines (Title 14 California Code of Regulations [CCR], § 15064.5), and PRC § 5024.1 (Title 14 CCR § 4850 et seq.), properties expected to be directly or indirectly affected by a proposed project must be evaluated for CRHR eligibility (PRC § 5024.1).

The purpose of the California Register of Historical Resources (CRHR) is to maintain listings of the state’s historical resources and to indicate which properties are to be protected, to the extent prudent and feasible, from material impairment and substantial adverse change. The term historical resources includes a resource listed in or determined to be eligible for listing in the CRHR; a resource included in a local register of historical resources; and any object, building, structure, site, area, place, record, or that a lead agency determines to be historically significant (CCR § 15064.5[a]). The criteria for listing properties in the CRHR were expressly developed in accordance with previously established criteria developed for listing in the National Register of Historic Places (NRHP). The California Office of Historic Preservation (OHP 1995:2) regards “any physical evidence of activities over 45 years old” as meriting recordation and evaluation.

1.1.1 CALIFORNIA REGISTER OF HISTORIC RESOURCES

A cultural resource is considered “historically significant” under CEQA if the resource meets one or more of the criteria for listing on the CRHR. The CRHR was designed to be used by state and local agencies, private groups, and citizens to identify existing cultural resources within the state and to indicate which of those resources should be protected, to the extent prudent and feasible, from substantial adverse change. The following criteria have been established for the CRHR. A resource is considered significant if it:

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

Chambers Group, Inc. 1 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California 2. is associated with the lives of persons important in our past; 3. embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or 4. has yielded, or may be likely to yield, information important in prehistory or history. In addition to meeting one or more of the above criteria, historical resources eligible for listing in the California Register must retain enough of their historic character or appearance to be able to convey the reasons for their significance. Such integrity is evaluated within regard to the retention of location, design, setting, materials, workmanship, feeling, and association.

Under CEQA, if an archeological site is not a historical resource but meets the definition of a “unique archeological resource” as defined in PRC § 21083.2, then it should be treated in accordance with the provisions of that section. A unique archaeological resource is defined as follows:

. An archaeological , object, or site about which it can be clearly demonstrated that, without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria:

o Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information

o Has a special and particular quality, such as being the oldest of its type or the best available example of its type

o Is directly associated with a scientifically recognized important prehistoric or historic event or person

Resources that neither meet any of these criteria for listing in the CRHR nor qualify as a “unique archaeological resource” under CEQA PRC § 21083.2 are viewed as not significant. Under CEQA, “A non- unique archaeological resource need be given no further consideration, other than the simple recording of its existence by the lead agency if it so elects” (PRC § 21083.2[h]).

Impacts that adversely alter the significance of a resource listed in or eligible for listing in the CRHR are considered a significant effect on the environment. Impacts to historical resources from a proposed project are thus considered significant if the project (1) physically destroys or damages all or part of a resource; (2) changes the character of the use of the resource or physical within the setting of the resource, which contributes to its significance; or (3) introduces visual, atmospheric, or audible elements that diminish the integrity of significant features of the resource.

2.1 PROJECT DESCRIPTION

Chambers Group has been contracted by Control Management, Inc., within the City of Jurupa Valley, Riverside County, California, to complete an Archaeological and Paleontological Literature Review and site survey for the proposed project, which includes a commercial development, convenience store, service station, car wash, restaurant building and parking lot.

The purpose of this investigation is to assess the potential for significant paleontological and archaeological deposits and/or materials within the proposed project area.

2.2 PROJECT LOCATION

The project area is located within the City of Jurupa Valley, Riverside County, California. Regional access to the project area is provided via Van Buren Boulevard, City of Jurupa Valley, Riverside County, California. The existing 16.22-acre project area is located between the southeast corner of Van Buren Blvd and Rutile Street. The parcel is bordered on the north and east by Van Buren Blvd, and the south and west by a housing development. Specifically, the project area is located on the USGS Fontana 7.5-Min Quadrangle.

Chambers Group, Inc. 3 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California SECTION 3.0 – SOURCES CONSULTED

A records search dated November 13, 2018, was obtained from the Eastern Information Center (EIC) at the University of California, Riverside (Appendix A), providing information on all documented cultural resources and previous archaeological investigations within 1 mile of the project area. Resources consulted during the records search conducted by the EIC included the National Register of Historic Places (NRHP), California Historical Landmarks, California Points of Historical Interest, and the California State Historic Resources Inventory. Results of the records search and additional research are detailed below.

3.1 REPORTS WITHIN THE STUDY AREA

Based upon the records search conducted by the EIC, 16 cultural resource projects have previously been completed within the 1-mile records search radius. One of these studies was within the current project area. Seven additional studies provide overviews of cultural resources in the general project vicinity (Table 1).

3.3 NATIVE AMERICAN HERITAGE COMMISSION AND AB 52 CONSULTATION

On November 7, 2018, Chambers Group requested that the Native American Heritage Commission (NAHC) conduct a search of its Sacred Lands File to determine if cultural resources important to Native Americans have been recorded in the project footprint and buffer area. On November 15, 2018, Chambers Group received a response from NAHC stating that the search of its Sacred Lands File did not indicate the presence of Native American cultural resources within 1-mile of the project area or surrounding vicinity (Appendix B). The NAHC provided a list of seven Native American tribal governments that may have knowledge of cultural resources near the project area. The seven Native American tribes identified by the NAHC were: (1) Gabrieleno Band of Mission Indians – Kizh Nation, (2) the Gabrieleno/ San Gabriel Band of Mission Indians, (3) the Gabrielino/Tongva Nation, (4) The Morongo Band of Mission Indians, (5) the San Manual Band of Mission Indians, (6) the San Manuel Band of Mission Indians, and (7) the Serrano Nation of Mission Indians. Because the City of Jurupa Valley is leading the Assembly Bill (AB) 52 consultation process, Chambers Group did not send consultation letters to the six affiliated tribes.

3.4 PALEONTOLGICAL RECORD SEARCH

Prior to the survey of the project area, a paleontological resources literature and records search was conducted by San Diego Natural History Museum (SDNHM) on November 21, 2018. This search included the current project area with an additional 1-mile radius. This search included a review of geological maps covering the project footprint to determine the fossil-bearing rock units underlying the project area. The objective of this records search was to identify fossil specimens or unique geological formations reported within the project area or surrounding 1-mile vicinity. Research also included a review of published and unpublished reports relevant to the paleontology and geology of the project area.

Results of the paleontological records search were positive for significant vertebrate fossil localities within the project area at depths below 5-10 feet below surface grade (Appendix C). The deposits at these levels are assigned high paleontological potential according to Riverside County guidelines, based on the possible presence of paleontological resources at an uncertain depth below existing surface grade.

Chambers Group, Inc. 7 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California SECTION 4.0 – BACKGROUND

4.1 GEOLOGIC SETTING

The APE is located in the city of Jurupa Valley, within Riverside County, on the USGS Fontana 7.5-Min Quadrangle. The Fontana quadrangle is located in the northern part of the Province within the northern part of the formation (MacKevett 1950). The Perris Block is a stable structural block bordered on the west by the and on the east by the . The Perris Block is capped by a series of erosional surfaces that are horizontal (Morton 1991:5).

The geology of the area consists primarily of old alluvial-fan deposits (late to middle ). These are mainly indurated, tan to brown, sandy to pebbly and cobbly, clay-bearing older alluvium. There are extensive deposits on the south side of the Jurupa Mountains. Locally the alluvial fan deposits are underlain by unconsolidated gray cobbly alluvium.

Due to the plate tectonics of California, fault lines follow a northerly trend, and mountain ranges (such as those of the Peninsular Mountain Ranges in ) normally follow this trend with some slight variance heading northwest. The Peninsular Ranges bordering the Upper Santa Ana Valley to the southwest and southeast are divided into three major, fault-bounded blocks. These ranges include the Santa Ana Mountains, Perris Mountains, and the San Jacinto Mountains. The Santa Ana Mountains, which lie southwest of Corona, divide the San Bernardino quadrangle and the surrounding inland area from the coast. The San Jacinto Mountains lie southeast of the San Bernardino and Santa Ana quadrangles and narrow to the northwest toward the convergence of the San Andreas and San Jacinto Fault Zones in the Cajon Pass slightly north of San Bernardino. The Perris Mountains lie between the San Jacinto and Elsinore- Chico fault zones, bounded on the north by the San Gabriel Fault (Morton et al. 2006: 11, 17, 73; Anderson et al. 2004: 2-3).

The Traverse Mountain Ranges, which include the San Bernardino Mountains and the , are east-trending. The San Gabriel Mountains form the central part of the Province, and the San Bernardino Mountains form the eastern part (Morton et al. 2006: 17). The zone separates the San Gabriel Mountains and San Bernardino Mountains and lying between these two mountain ranges is the relatively low-lying Cajon Pass area (Morton et al. 2006: 17). The San Jacinto Fault is a young, major element of the San Andreas Fault system, originating from the San Andreas at the southeast margin of the San Gabriel Mountains in Cajon Creek. The San Jacinto Fault divides the San Gabriel Mountains from the San Bernardino Mountains, and extends southeastward, passing through San Bernardino with a more southerly strike than the San Andreas Fault Zone. It is seismically the most active fault zone in Southern California and has generated a large number of destructive earthquakes in historic times (Morton et al. 2006: 73; Anderson et al. 2004: 2-3).

4.2 PALEONTOLOGICAL ENVIRONMENT

Starting in the Tertiary period, a general warming of the climate took place in Southern California that reached its peak in the middle Miocene. During the late Miocene period, the climate was cooler and had numerous playa lakes with woody areas and grassy plains (Park and Downing 2001: 181-182).

The paleontological environment in Southern California during the Pleistocene Epoch was cooler and wetter than it is today. Similar to conditions during the late Miocene, the Mojave Desert at this time retained a multitude of major lakes and rivers. Likewise, the Los Angeles Basin was crisscrossed by many

Chambers Group, Inc. 8 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California rivers and streams, the largest now known as the Los Angeles River (USGS 2008). The constant flooding and high volume of water that ran through these channels formed a riparian marsh environment that was very rich in plant and animal taxa.

Pleistocene biotas were similar to the modern environment and many genera of Pleistocene-era plants and animals are still present today. Conversely, the Pleistocene was also characterized by the presence of distinctively large species of land mammals and birds. Megafauna such as mammoth, mastodon, saber- toothed cat, bison, ground sloths, short-faced bear, and dire wolves are a few of the species that inhabited North America, Europe, and Asia during this epoch. Horses, elephants, and lions lived in the plains of North America, while birds with wingspans exceeding 25 feet soared above. By the end of the Pleistocene (approximately 15,000 years ago) all these animals became extinct.

4.3 GABRIELENO AND SERRANO CULTURE HISTORY

4.3.1 Gabrieleno Archaeology and Ethnography

The Shoshonean migration marks the arrival of Uto-Aztecan speakers to Southern California. The Gabrielino, a branch of Shoshonean, arrived around 500 B.C. Their language has been identified as Cupon language which is part of the larger Uto-Aztecan (Johnston 1962).

At the time of Spanish contact, the Gabrielino inhabited a rich coastal and inland region of Southern California consisting of present day Los Angeles and Orange Counties, including San Nicolas, San Clemente and Santa Catalina Islands (Bean and Smith 1978). Second only to the Chumash, the Gabrielino were the wealthiest, most populous, and most powerful ethnic group in southern California (Moratto 1984). Settlement pattern studies concluded there is a presence of both primary villages that were occupied year-round and secondary temporary camps inhabited at various times of the season. Both primary and temporary settlements seemed to be located near water sources (Bean and Smith 1978).

Their cultural was very similar to that of the Chumash despite marked differences in language, mortuary practices, and the manufacture and use of . The Gabrielino influenced cultures as far north as the San Joaquin Valley , as far east as the Colorado River, and south into Baja California.

The Majority of Gabrielino artifacts reflect an ornate craftsmanship with everyday use items often decorated with asphaltum and shell inlaid, paintings and rare minerals. The Gabrielino established a well versed economic system focusing on trading goods, food reserves, and disturbed resources. The Gabrielino quarried steatite from Santa Catalina Island and often traded with neighboring tribes. Steatite items are highly diagnostic of the Gabrielino; and it was used to make pipes, animal carvings, vessels, and ornaments (Bean and Smith 1978).

The Gabrielino houses were circular structures thatched with tule, fern, or carrizo (weeds). Some houses were recorded as as large as 60 ft in diameter. Sweathouses, menstrual , and ceremonial enclosures were other common structures found in villages (Bean and Smith 1978).

Unfortunately, most of the Gabrielinos were gone long before systematic ethnographic studies could be completed. As a result, knowledge of their cultural and lifeways is sparse (Bean and Smith 1978).

Chambers Group, Inc. 9 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California 4.3.2 Serrano Archaeology and Ethnography

The Serrano language is classified as being within the Takik (Bean and Smith 1978:570). The Serrano lived in the San Bernardino Mountains east of the Cajon Pass to as far east as present-day Twentynine Palms and as far south as the Yucaipa Valley (Bean and Smith 1978:570). The Serrano had exogamous moieties made up of exogamous, patrilineal clans (Bean and Smith 1978:572). Lineage and clan leaders were hereditary ceremonial leaders who controlled sacred bundles and lived in ceremonial houses (Bean and Smith 1978:571–572).

The Serrano were organized into local lineages occupying favored territories but rarely claiming any territory far from the lineage’s home base (Bean and Smith 1978). The estimated population of the Serrano before European contact was 1,500-2,500. It is difficult to estimate the number of Serranos living in each village however, it is likely that the villages held only as many Serranos as could be accommodated by water sources (Stickle and Weinman-Roberts 1980).

The Serrano lived in dwellings which were circular, domed structures built over an excavated area. These structures were built with fire pits and primarily served as sleeping areas. Ceremonial houses were the only other buildings in the villages and were normally occupied by the village priest (Stickle and Weinman- Roberts 1980).

In the Serrano artifact assemblage, it is noted to be similar to that of the neighboring and includes musical instruments such as rattles and flutes; utensils and ornaments such as fire drills, mortars, , pipes, beads, awls, and projectile points from wood, shell, bone, and stone. The Serrano were talented pottery and makers. Their pots were made of coiled clay smoothed out with a paddle and set in the sun to dry before being fired in a pit. Serrano Brown ware was sometimes decorated with designs of circles and lines of either red or black (Stickle and Weinman-Roberts 1980).

The Serrano were also known for their . Abstract and geometric designs are often see with representational figures of sheep, lizards (zoomorphs) and human beings (anthropomorphs). Researchers have proposed that the petroglyphs were records of important events, rough maps, and artistic representations of native life (Stickle and Weinman-Roberts 1980).

4.4 PREHISTORY

It is generally agreed that human occupation of Southern California began at least 10,000 years before present (BP). The archaeological record indicates that between approximately 10,000 and 6,000 years BP, a predominantly hunting and gathering economy existed, characterized by archaeological sites containing numerous projectile points and the remains of butchered large animals. The most heavily exploited species were likely those species still alive today. Bones of extinct species have been found in the region but, unlike other regions of the continent, are not definitively associated with cultural artifacts in California. Although small animal bones and plant grinding are rarely found within archaeological sites of this period, small game and vegetal foods were likely exploited on a widespread basis. A lack of intact stratified cultural deposits from this period suggests small groups practiced high residential mobility during this period (Wallace 1978).

The three major periods of prehistory for the greater Los Angeles Basin region have been refined by research using radiocarbon dates from archaeological sites in coastal Southern California (Koerper and Drover 1983; Mason and Peterson 1994):

Around 6,000 years BP, a shift in focus from hunting toward a greater reliance on vegetal resources occurred. Archaeological evidence of this trend consists of a much greater number of milling tools (e.g., metates and manos) for processing seeds and other vegetable matter (Wallace 1978). This period, known to archaeologists as the Millingstone Period, was a long period of time characterized by small, mobile groups that likely relied on a seasonal round of settlements that included both inland and coastal residential bases. Seeds from sage and grasses, rather than acorns, provided calories and carbohydrates. Faunal remains from sites dating to this period indicate similar animals were hunted. Inland Millingstone sites are characterized by numerous manos, metates, and . Shell are common at coastal Millingstone sites. Coarse-grained lithic materials, such as quartzite and rhyolite, are more common than fine-grained materials in flaked stone tools from this time. Projectile points are found in archaeological sites from this period, but they are far fewer in number than from sites dating to before 6,000 years BP. An increase in the size of groups and the stability of settlements is indicated by deep, extensive middens at some sites from this period (Wallace 1978).

In sites post-dating roughly 3,000 years BP, archaeological evidence indicates the reliance on both plant gathering and hunting continued and was more specialized and locally adapted to particular environments. Mortars and pestles were added to metates and manos for grinding seeds and other vegetable material. Chipped-stone tools became more refined and specialized, and bone tools were more common. During this period, new peoples from the Great Basin began entering Southern California. These immigrants, who spoke a Uto-Aztecan language, seem to have displaced or absorbed the earlier population of Hokan-speaking peoples. The exact time of their entry into the region is not known; however, they were present in Southern California during the final phase of prehistory. During this period, population densities were higher than before; and settlement became concentrated in villages and communities along the coast and interior valleys (Erlandson 1994; McCawley 1996). During the Intermediate Period, mortars and pestles appeared, indicating the beginning of acorn exploitation. Use of the acorn – a high-calorie, storable food source – probably allowed greater sedentism and facilitated an increased level of social organization. Large projectile points from archaeological sites of this period indicate that the bow and , a hallmark of the Late Prehistoric Period, had not yet been introduced; and hunting was likely accomplished using the atlatl ( thrower) instead. Settlement patterns during this time are not well understood. The semi-sedentary settlement pattern characteristic of the Late Prehistoric Period may have begun during the Intermediate Period, although territoriality may not yet have developed partially because of lower population densities. Regional subcultures also started to develop, each with its own geographical territory and language or dialect (Kroeber 1925; McCawley 1996; Moratto 1984). These were most likely the basis for the groups encountered by the first Europeans during the eighteenth century (Wallace 1978). Despite the regional differences, many material culture traits were shared among groups, indicating a great deal of interaction (Erlandson 1994). The Late Prehistoric Period is better understood than earlier periods largely through ethnographic analogy made possible by ethnographic and anthropological research of the descendants of these groups in in the late nineteenth and early twentieth centuries.

The first significant European settlement of California began during the Spanish Period (1769 to 1821) when 21 missions and four presidios were established between San Diego and Sonoma. Although located primarily along the coast, the missions dominated economic and political life over the greater California region. The purpose of the missions was primarily for political control and forced assimilation into Spanish society and Catholicism of the Native American population, along with economic support to the presidios (Castillo 1978).

The Mexican Period (1821-1848) began with the success of the Mexican Revolution in 1821, but changes to the mission system were slow to follow. When secularization of the missions occurred in the 1830s, their vast land holdings in California were divided into large land grants called ranchos. The Mexican government granted ranchos throughout California to Spanish and Hispanic soldiers and settlers (Castillo 1978; Cleland 1941). Even after the decree of secularization was issued in 1833 by the Mexican Congress, missionaries continued to operate a small diocesan church. In 1834, the San Gabriel Mission was turned over to the civil administrator which included over 16,000 cattle (Hoover et al 1990: 150- 177).

In 1848, The Treaty of Guadalupe Hidalgo ended the Mexican-American War and marked the beginning of the American Period (1848 to present). The discovery of gold that same year sparked the 1849 California Gold Rush, bringing thousands of miners and other new immigrants to California from various parts of the , most of whom settled in the north. For those settlers who chose to come to Southern California, much of their economic prosperity was fueled by cattle ranching rather than by gold. This prosperity, however, came to a halt in the 1860s as a result of severe floods and droughts, as well as legal disputes over land boundaries, which put many ranchos into bankruptcy (Castillo 1978; Cleland 1941).

The City of Jurupa Valley is located on a portion of the land known during the Spanish Period as . Rancho Jurupa was created in 1838 under a land grant to Señor Don Juan Bandini by the Mexican Government. The city was incorporated in 2011. Prior to this time the area was an unincorporated community of Riverside County.

Chambers Group, Inc. 12 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California SECTION 5.0 – FIELD METHODS

Chambers Group survey teams are trained in established field methods and adept at identifying the entire range of cultural resources likely found for each project. Cultural materials encountered may include prehistoric artifacts (e.g., flaked stone tools, -making debris, stone milling tools), historic-period artifacts (e.g., metal, glass, ceramics), sediment discoloration that might indicate the presence of a cultural , as well as depressions and other features indicative of the former presence of structures or buildings (e.g., post holes, foundations).

On November 28, 2018, Chambers Group archaeologist Kyle Knabb completed an archaeological reconnaissance survey of the project area. The project site was surveyed using transects spaced no greater than 15-meters apart and oriented in a north-south direction. Dr. Knabb was equipped with a sub-meter accurate GPS unit for recording spatial data and documented the survey area and all findings with a high- resolution digital camera.

The archaeologist examined exposed ground surface for artifacts (e.g., flaked stone tools, tool-making debris, milling tools, ceramics), ecofacts (e.g., marine shell and bone), soil discoloration that might indicate the presence of a cultural midden, and features indicative of the former presence of structures or buildings (e.g., standing exterior walls, postholes, foundations) or historic debris (e.g., metal, glass, ceramics). Ground disturbances such as burrows were visually inspected for both cultural resources and paleontological resources.

Chambers Group, Inc. 13 21130 Archaeological and Paleontological Assessment Report for a Commercial Development on the corner of Van Buren Blvd and Rutile Street Jurupa Valley, Riverside County, California SECTION 6.0 – RESULTS AND CONCLUSIONS

Chambers Group conducted archaeological and paleontological investigations within the Jurupa Valley Phase I Cultural Resources and Paleontological Study Project APE in November 2018. The work was performed under Chambers Group’s contract with Control Management, Inc. The main goal of the archaeological investigations was to gather and analyze information needed to determine if the project would impact cultural and paleontological resources.

An archival records search, background studies, and intensive pedestrian survey of the project area were conducted as part of a Phase I cultural resource study. The NAHC Sacred Lands File search did not identify any sacred sites or tribal cultural resources within the search radius. The CHRIS record search identified one cultural resource study and no archaeological sites within the project area. The paleontological records search identified sensitive deposits at depths of 5-10 feet below the surface.

Because no cultural resources were identified within the APE as a result of the record search or the pedestrian survey, no impacts to cultural resources are expected as part of the proposed project. However, since Pleistocene alluvial deposits with a high potential for bearing significant paleontological resources were identified below the surface, Chambers Group recommends implementing a paleontological resource mitigation program during ground-disturbing activities if excavation depths exceed approximately 5-10 feet below surface grade.

RE: 21130 Jurupa Valley, Riverside county.

Dear Mr. Knabb:

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

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

If you receive notification of change of addresses and phone numbers from tribes, please notify me. With your assistance we are able to assure that our lists contain current information. If you have any questions or need additional information, please contact me at my email address: [email protected].

RE: Paleontological Records Search – 21130 Jurupa Valley Phase I Survey Project

Dear Dr. Knabb: This letter presents the results of a paleontological records search conducted for the 21130 Jurupa Valley Phase I Survey Project (Project), located in the west central portion of the City of Jurupa Valley, Riverside County, California. The Project site is bordered to the northeast by Van Buren Boulevard, to the west by Rutile Street, and to the south by residential development. A review of published geological maps covering the Project site and surrounding area was conducted to determine the specific geologic units underlying the Project. Each geologic unit was subsequently assigned a paleontological resource potential following Riverside County and Society of Vertebrate Paleontology (SVP) guidelines (e.g., SVP, 2010). Published geological reports (e.g., Morton and Miller, 2006) covering the Project area indicate that the proposed Project has the potential to impact Pleistocene-age alluvial deposits. This geologic unit and its paleontological potential are summarized in detail in the following section. In addition, a search of the paleontological collection records housed at the San Diego Natural History Museum (SDNHM) was conducted in order to determine if any documented fossil collection localities occur at the Project site or within the immediate surrounding area (Figure 1). The SDNHM does not have any recorded fossil localities within one mile of the Project site.

Geologic Rock Units Underlying the Project Area Pleistocene alluvial deposits – The entire Project site is underlain by Pleistocene-age alluvial deposits—specifically, by middle Pleistocene-age old alluvial-fan deposits, Unit 1 (Qof1) of Morton and Miller (2006). The SDNHM does not have any fossil localities from Pleistocene-age alluvial deposits within a 1-mile radius of the Project site. Elsewhere in the lowlands of western Riverside County, Pleistocene-age alluvial deposits have produced important fossilized remains of terrestrial vertebrates, particularly of large-bodied mammals, including ground sloth, mammoth, mastodon, camel, bison, dire wolf, sabertoothed cat, American lion, and giant short-faced bear (e.g., Anderson et al., 2002; Jefferson, 1991; Springer et al., 2009, 2010). Old alluvial-fan deposits underling the Project site are considered to be unlikely to contain significant fossils in the uppermost layers, but may contain fossils at an unknown depth. As a general rule, a threshold of approximately 5–10 feet below surface grade is used to determine whether excavations are likely to impact paleontological resources in Pleistocene alluvial deposits. These deposits are therefore assigned a high paleontological potential B according to Riverside County guidelines, based on the possible presence of paleontological resources at an uncertain depth below existing surface grade.

Summary and Recommendations The high paleontological potential B rating of Pleistocene alluvial deposits in Riverside County suggests that construction of the proposed Project could result in impacts to paleontological resources if excavation depths exceed approximately 5–10 feet below surface grade. In this case, implementation of a complete paleontological resource mitigation program during ground-disturbing activities is recommended. If you have any questions concerning these findings please feel free to contact me at 619-255- 0321 or [email protected].
