The property, varying between 10-20 feet below mean sea level, was developed as a residential and equestrian compound built during the late 1970's through mid-1980's, and was formerly owned by the late Mery Griffin. The property is bordered by the Griffin Ranch residential project to the south, east and west, with the Madison Club development across Avenue 54 to the north. The City is currently processing development applications proposing to subdivide the site into 78 single-family lots, leaving the original Mery Griffin estate intact and expanding the existing 2.1-acre pond to a 6-acre lake. A Phase I (survey level) Historical/Archaeological Resources Survey was completed for the subject property. The Survey includes a record search and field survey of the property. As per SB 18 procedure, the City requested comments from tribal contacts provided by the Native American Heritage Commission. The 90-day consultation period passed with no consultation requests or specific comments on the project being received. A Paleontological Resources Assessment was also completed for the property, which includes a field survey, records search, findings from the area and personnel qualifications. Historic Preservation Commission Staff Report - February 20, 2014 Page 1 of 4 These reports, when accepted, will be part of the environmental review required by the California Environmental Quality Act (CEQA) for the project application. DISCUSSION: Historical/Archaeological Resources Survey - A comprehensive records search and on - site investigation were conducted on the project site by CRM Tech. CRM Tech also contacted local Tribes and received no information identifying traditional cultural sites on or in the vicinity of the project site. The records search determined that the site was not previously surveyed. However, more than 30 prior studies have historically been conducted within one mile of the project site. These studies uncovered 24 historic/archaeological sites and 63 isolates (sites with less than 3 artifacts). As none of these were recorded in the project site's immediate vicinity, no further consideration under this survey is warranted. The on -site investigation identified no historic or prehistoric materials within the project area. Historical sources consulted suggest the area remained mostly undeveloped by man until the 1950's. No evidence of any buildings constructed prior to 1978 was found; all existing buildings on the site are consistent with the period during which Mr. Griffin developed the property and are considered modern. Overall, the entire project area has been disturbed by past development. The field survey showed no potential for cultural resources on the site. CRM Tech concluded that the proposed project will not cause a substantial adverse change to any known historic resource, no further cultural resource investigation is necessary, and has recommended that, should any cultural materials be unearthed, all work in that area should be halted so that the materials can be examined and evaluated by a qualified archaeological monitor. HPC policy requires monitoring in this part of the City regardless of whether artifacts were found during a Phase I survey. Paleontological Resources Assessment — CRM Tech conducted a review of previous records searches in the project vicinity through the Natural History Museum of Los Angeles County, and the San Bernardino County Museum in Redlands. Additionally, a literature search of the consultant's in-house library and personal records was also conducted. Though the results indicate that no paleontological localities have been discovered within or in the immediate vicinity of the project site, several localities have been previously reported in nearby areas that share the project area's soils characteristics. The San Bernardo County Museum finds the project vicinity to have a "high paleontological sensitivity" and that the project has a "high potential to impact significant nonrenewable fossil resources." The Natural History Museum reflects a similar concern. A field survey was conducted on April 4, 2014, by CRM Tech staff. While it was noted that development activities have heavily disturbed the project area, scattered shells and Historic Preservation Commission Staff Report - February 20, 2014 Page 2 of 4 shell fragments of freshwater species were observed, which attribute the project site to being located within the Holocene Lake Cahuilla lakebed sequence. The report concludes that the proposed site may contain sediments from which many Holocene localities are known to have been found. It was also concluded that some of these sediments may be present beneath the site and are considered as high paleontological sensitivity. Due to the extensively disturbed condition of the site, periodic monitoring is recommended for demolition, grubbing and shallow grading (up to a 2 foot depth) and a paleontologic mitigation program to mitigate impacts to be developed and implemented by a qualified monitor equipped to salvage, collect, record, identify, and preserve unearthed fossils. Historic Preservation Commission policy has been to require monitoring of the entire site during its rough grading as well as trenching if the initial field survey found any fossil mollusk shells on the surface. RECOMMENDATION: Adopt Minute Motion 2015- , accepting the "Historical/Archaeological Resources Survey; Mery Griffin Estates Project" prepared by CRM Tech for 81345 Avenue 54, and recommend to the Planning Commission the following requirements: • If buried cultural materials are discovered during any earth -moving operations associated with the project, all work in that area shall be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds. • If any resource recovery occurs, a final report shall be submitted to the Community Development Department prior to the issuance of the first Certificate of Occupancy for the project. • Collected archaeological resources shall be properly packaged for long term curation, in polyethylene self -seal bags, vials, or film cans as appropriate, all within acid -free, standard size, comprehensively labeled archive boxes and delivered to the City prior to issuance of first Certificate of Occupancy for the property. Materials shall be accompanied by descriptive catalogue, field notes and records, primary research data, and the original graphics. 2. Adopt Minute Motion 2015- , accepting the "Paleontological Resources Assessment Report; Mery Griffin Estates Project" prepared by CRM Tech for 81345 Avenue 54, and recommend to the Planning Commission the following requirements: • A paleontological resource impact mitigation program shall be developed and implemented for the proposed project in accordance with the provisions of Historic Preservation Commission Staff Report - February 20, 2014 Page 3 of 4 CEQA, as well as the proposed guidelines of the Society of Vertebrate Paleontology. The primary component of the mitigation program will be monitoring of ground disturbances during the project by qualified personnel. Since the surface soils have been extensively disturbed in the past, only periodic monitoring is recommended during demolition, tree removal, grubbing, or shallow surface grading. Continuous monitoring shall be conducted for deeper grading and excavations that reach beyond a depth of two feet. The mitigation program should include but not belimited to the following: • On- and off -site monitoring of earth -moving and grading in areas identified as likely to contain paleontological resources shall be conducted by a qualified paleontological monitor. The monitor should be prepared to quickly salvage fossils, if they are unearthed, to avoid construction delays, but must have the power to temporarily halt or divert construction equipment to allow for removal of abundant or large specimens. Proof that a monitor has been retained shall be given to City prior to issuance of first earth -moving permit, or before any clearing of the site is begun. • Samples of sediments should be collected and washed to recover small invertebrate and vertebrate fossils. • Recovered specimens should be identified and curated at a repository with permanent retrievable storage that would allow for further research in the future. • A report of findings with an appended itemized inventory of specimens shall be submitted to the City prior to the first occupancy of a residence being granted by the City. The report shall include pertinent discussions of the significance of all recovered resources where appropriate. The report and inventory, when submitted to the City, will signify completion of the program to mitigate impacts to paleontological resources. • Collected resources and related reports, etc. shall be given to the City for curation. Packaging of resources, reports, etc. shall comply with standards commonly used in the paleontological industry.

The project area consists of approximately 40 acres of land in Assessor's Parcel Number 767-320-013, occupied by an extensive residential compound with associated equestrian and other recreational facilities. It is located at 81-345 Avenue 54, between Madison Street and Monroe Street, in the northwest quarter of Section 15, T6S R7E, San Bernardino Baseline and Meridian. The study is part of the environmental review process for the Griffin Estates project, which proposes to subdivide of the property for single-family residential development while retaining the core of the existing residential compound. The City of La Quinta, as the lead agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA) and the City's Historic Preservation Ordinance. The purpose of the study is to provide the City with the necessary information and analysis to determine whether the proposed project would cause substantial adverse changes to any "historical resources," as defined by CEQA, that may exist in or around the project area. In order to identify such resources, CRM TECH conducted a historical/archaeological resources records search, pursued historical background research, contacted Native American representatives, and carried out an intensive -level field survey. Through these various avenues of research, this study did not encounter any "historical resources" within or adjacent to the project area. Therefore, CRM TECH recommends to the City of La Quinta a finding of No Impact regarding cultural resources. No further cultural resources investigation is recommended for the project unless development plans undergo such changes as to include areas not covered by this study. However, if buried cultural materials are encountered during any earth - moving operations associated with the project, all work in that area should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds.

The project area consists of approximately 40 acres of land in Assessor's Parcel Number 767-320-013, occupied by an extensive residential compound with associated equestrian and other recreational facilities. It is located at 81-345 Avenue 54, between Madison Street and Monroe Street, in the northwest quarter of Section 15, T6S R7E, San Bernardino Baseline and Meridian (Fig. 2). The study is part of the environmental review process for the Griffin Estates project, which proposes to subdivide of the property for single-family residential development while retaining the core of the existing residential compound. The City of La Quinta, as the lead agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA; PRC §21000, et seq.) and the City's Historic Preservation Ordinance (Title 7, La Quinta Municipal Code). The purpose of the study is to provide the City with the necessary information and analysis to determine whether the proposed project would cause substantial adverse changes to any "historical resources," as defined by CEQA, that may exist in or around the project area. In order to identify such resources, CRM TECH conducted a historical/archaeological resources records search, pursued historical background research, contacted Native American representatives, and carried out an intensive -level field survey. The following report is a complete account of the methods, results, and final conclusion of the study. kr- - i n ?1 7. u " di A j 1 Im deSeTt s �'c t7rk` m L7eSSFf Project___ -, `- �• r�� G - Itaaio tow. � 7. �.-i '-� :" KEIA�r �, location 1. two rr a 4 c75 .: 4•. � s ) `t�� .� Y -�I n I Cerny !]]1�. � �, & Acdes Ranch S !

Project area. (Based on USGS Indio and La Quinta, Calif., 1:24,000 quadrangles [USGS 1972; 1980]) 2 SETTING CURRENT NATURAL SETTING The project area is situated in the Coachella Valley, a northwest -southeast trending desert valley that constitutes the western end of the Colorado Desert. Dictated by this geographic setting, the climate and environment of the project area and its surrounding region are typical of southern California's desert country, marked by extremes in temperature and aridity. Temperatures in the region reach over 120 degrees in summer, and dip to near freezing in winter. Average annual precipitation is less than five inches, and the average annual evaporation rate exceeds three feet. As mentioned above, the project area is occupied by a number of buildings and other facilities of the former Mery Griffin estate, including the main residence, guesthouses, gazebos, and a pond in the northwestern portion, stables and corrals in the northeastern portion, and an equestrian racetrack in the southern portion (Fig. 3). Elevations on the property range around 10-20 feet below mean sea level, and the terrain is relatively level with a slight incline to the northwest. Soils consist of light grey fine sands mixed with freshwater shells, and the vegetation observed in the project area includes both introduced landscaping plants and some native vegetation, such as palms, palo verdes, tamarisks, eucalyptuses, pepper trees, and small desert shrubs and grasses (Fig. 3). CULTURAL SETTING Prehistoric Context Numerous investigations on the history of cultural development in southern California have led researchers to propose a number of cultural chronologies for the desert regions. A specific cultural Figure 3. Typical landscapes within the project area. Clockwise from top left: view to the south across the equestrian racetrack; landscaping waste; existing buildings; shell deposits in the surface soils. (Photos taken on April 30, 2014) 3 sequence for the Colorado Desert was offered by Schaefer (1994) on the basis of the many archaeological studies conducted in the area. The earliest time period identified is the Paleoindian (ca. 8,000 to 10,000-12,000 years ago), when "small, mobile bands" of hunters and gatherers, who relied on a variety of small and large game animals as well as wild plants for subsistence, roamed the region (ibid.:63). These small groups settled "on mesas and terraces overlooking larger washes" (ibid.:64). The artifact assemblage of that period typically consists of very simple stone tools, "cleared circles, rock rings, [and] some geoglyph types" (ibid.). The Early Archaic Period follows and dates to ca. 8,000 to 4,000 years ago. It appears that a decrease in population density occurred at this time and that the indigenous groups of the area relied more on foraging than hunting. Very few archaeological remains have been identified to this time period. The ensuing Late Archaic Period (ca. 4,000 to 1,500 years ago) is characterized by continued low population densities and groups of "flexible" sizes that settled near available seasonal food resources and relied on "opportunistic" hunting of game animals. Groundstone artifacts for food processing were prominent during this time period. The most recent period in Schaefer's scheme, the Late Prehistoric, dates from ca. 1,500 years ago to the time of the Spanish missions, and saw the continuation of the seasonal settlement pattern. Peoples of the Late Prehistoric Period were associated with the Patayan cultural pattern and relied more heavily on the availability of seasonal "wild plants and animal resources" (Schaefer 1994:66). It was during this period that brown and buff ware ceramics were introduced into the region. The shores of Holocene Lake Cahuilla, during times of its presence, attracted much settlement and resource procurement; but in times of the lake's desiccation around 1700, according to Schaefer (1994:66), the Native people moved away from its receding shores towards rivers, streams, and mountains. Numerous archaeological sites dating to this time period have been identified along the shoreline of Holocene Lake Cahuilla. Testing and mitigative excavations at these sites have recovered brown and buff ware ceramics, a variety of groundstone and projectile point types, ornaments, and cremations. Ethnohistoric Context The Coachella Valley is a historical center of Native American settlement, where U.S. surveyors noted large numbers of Indian villages and rancherias, occupied by the Cahuilla people, in the mid- 19th century. The Takic-speaking Cahuilla are generally divided by anthropologists into three groups, according to their geographic setting: the Pass Cahuilla of the San Gorgonio Pass -Palm Springs area, the Mountain Cahuilla of the San Jacinto and Santa Rosa Mountains and the Cahuilla Valley, and the Desert Cahuilla of the eastern Coachella Valley. The basic written sources on Cahuilla culture and history include Kroeber (1925), Strong (1929), and Bean (1978). The following ethnohistoric discussion is based primarily on these sources. The Cahuilla did not have a single name that referred to an all-inclusive tribal affiliation. Instead, membership was in terms of lineages or clans. Each lineage or clan belonged to one of two main divisions of the people, known as moieties. Members of clans in one moiety had to marry into clans from the other moiety. Individual clans had villages, or central places, and territories they called L! their own, for purposes of hunting game, gathering food, or utilizing other necessary resources. They interacted with other clans through trade, intermarriage, and ceremonies. The Cahuilla people were primarily hunters and gatherers who exploited nearly all of the resources available in a highly developed seasonal mobility system. They were adapted to the and conditions of the desert floor, the lacustral cycles of Holocene Lake Cahuilla, and the environments of the nearby mountains. When the lake was full, or nearly full, the Cahuilla would take advantage of the resources presented by the body of fresh water. Once the lake had desiccated, they utilized the available terrestrial resources. They also migrated to the higher elevations of the nearby mountains to take advantage of the resources and cooler temperatures available in that environment. The Cahuilla collected seeds, roots, wild fruits and berries, acorns, wild onions, pinon nuts, and mesquite and screw beans. Common game animals included deer, antelope, big horn sheep, rabbits, wood rats and, when Holocene Lake Cahuilla was present, fish and waterfowls. The Cahuilla hunted with throwing sticks, clubs, nets, traps, snares, as well as bows and arrow (Bean 1978; CSRI 2002). Common tools and utensils included manos and metates, mortars and pestles, hammerstones, fire drills, awls, arrow -straighteners, and stone knives and scrapers. These lithic tools were made from locally available material as well as exotic material procured through trade or travel. They also used wood, horn, and bone spoons and stirrers; baskets for winnowing, leaching, grinding, transporting, parching, storing, and cooking; and pottery vessels for carrying water, storage, cooking, and serving food and drink (ibid.). Population data prior to European contact are almost impossible to obtain, but estimates range from 3,600 to as high as 10,000 persons. During the 19th century, however, the Cahuilla population was decimated as a result of European diseases, most notably smallpox, for which the Native peoples had no immunity. Today, Native Americans of Pass or Desert Cahuilla heritage are mostly affiliated with one or more of the Indian reservations in and near the Coachella Valley, including Torres Martinez, Augustine, Agua Caliente, Cabazon, and Morongo Historic Context In 1823-1825, Josh Romero, Josh Maria Estudillo, and Romualdo Pacheco became the first noted European explorers to travel through the Coachella Valley when they led a series of expeditions in search of a route to Yuma (Johnston 1987:92-95). Due to its harsh environment, few non -Indians ventured into the desert valley during the Mexican and early American periods, except those who traveled along the established trails. The most important of these trails was the Cocomaricopa Trail, an ancient Indian trading route that was "discovered" in 1862 by William David Bradshaw and known after that as the Bradshaw Trail (Gunther 1984:71; Ross 1992:25). In much of the Coachella Valley, this historic wagon road traversed a similar course to that of present-day Highway 111. During the 1860s-1870s, the Bradshaw Trail served as the main thoroughfare between coastal southern California and the Colorado River, until the completion of the Southern Pacific Railroad in 1876-1877 brought an end to its heyday (Johnston 1987:185). Non -Indian settlement in the Coachella Valley began in the 1870s with the establishment of railroad stations along the Southern Pacific Railroad, and spread further in the 1880s after public land was opened for claims under the Homestead Act, the Desert Land Act, and other federal land laws 5 (Laflin 1998:35-36; Robinson 1948:169-171). Farming became the dominant economic activity in the valley thanks to the development of underground water sources, often in the form of artesian wells. Around the turn of the century, the date palm was introduced into the Coachella Valley, and by the late 1910s dates were the main agricultural crop and the tree an iconic image celebrating the region as the "Arabia of America" (Shields Date Gardens 1957). Then, starting in the 1920s, a new industry featuring equestrian camps, resorts, hotels, and eventually country clubs began to spread throughout the Coachella Valley, transforming it into southern California's premier winter retreat. In today's City of La Quinta, the earliest settlement and land development activities did not occur until the turn of the century (BLM n.d.). In 1926, with the construction of the La Quinta Hotel, the development of La Quinta took on the character of a winter resort, typical of the desert communities along Highway 111. Beginning in the early 1930s, the subdivision of the cove area of La Quinta and the marketing of "weekend homes" further emphasized this new direction of development (City of La Quinta 1997:43). On May 1, 1982, La Quinta was incorporated as the 19th city in Riverside County. RESEARCH DESIGN Scientific research should be directed by a theoretical orientation that is geared toward gathering data to answer questions of current research interest. While numerous theoretical orientations have been put forward and used to guide archaeological research and to improve data -collecting efforts, the cultural ecology approach still tends to be the most useful paradigm in archaeological endeavors, although it is often used in conjunction with newer models. Basically, the cultural ecology approach to understanding cultural development contends that people develop behavioral patterns in order to exploit the resources of the area by means of particular technologies. It also assumes that there is interrelationship of these technologies, the environment, survival, and other aspects of the culture. Since archaeology deals mostly with the cultural remains that are left long after the people are gone, this theoretical orientation has obvious advantages for archaeological research, although it is left to the archaeologist to determine the extent to which the behavior patterns used to exploit the environment affect other aspects of culture. Because of its continuing usefulness, the cultural ecology theoretical orientation is the basis of the historical/archaeological investigation used in this study. In practice, a research design serves to identify research issues and to illuminate new information for the purpose of evaluating the significance of cultural resources present within a study area. While no overarching research design has been established for this part of Riverside County, a standard set of research questions, or research domains, can be applied to historical/archaeological investigations in the region, especially for Phase I studies such as this. The primary goal of a Phase I survey is to identify any prehistoric or historic -period cultural resources that may be present within the study area. This identification process generally includes a historical/archaeological resources records search, historical background research, Native American contacts, and a field inspection. While little detailed data may be available from the research methods employed during Phase I studies, some types of data gathered during the investigation may be used to address research issues, at least on a basic level. For instance, just the presence of cultural G resources on a property indicates that people used the area. Other research questions, such as those posited below, can be addressed during Phase I studies only if certain types of artifacts or features are found within or near the study area. • Is there any evidence that important events took place on the property or that the property is associated with a historically important person? • Can anything be learned regarding the time period the area was used? Can it be determined whether people used the area during early or late prehistoric times, or during the historic period? • Can anything be learned about the duration of the use of the land? Was the land used continuously for a long period of time, was it used only briefly, or was it used repeatedly over time? • Can anything be learned about the subsistence strategies of the people who used the land? Is there any evidence visible on the surface that indicates what food resources were being processed and/or consumed? Is there any evidence regarding the preparation of the food resources? • Would any of the information gathered during a Phase I study shed light on settlement patterns? Could activities in the study area be related with broader patterns of human habitation of the region? Did the people live on the property or use it only for resource procurement? If they lived on the property, was it a dense or sparse population? Does occupation of the subject property disclose any information regarding settlement strategies or preferences? • Are there historical/archaeological data to be obtained about trade, travel, or cultural interactions? In addition, a research design should also outline major themes in the prehistory and history of a region or specific area, so that any cultural resources encountered during a Phase I study could be evaluated within the proper context. Based on the prehistoric, ethnohistoric, and historic contexts discussed above, the following themes can be established for past human activities in the vicinity of the current project area: • Exploitation of natural resources by Native Americans during the prehistoric and proto-historic periods; • European/American exploration in the Coachella Valley, especially along the historic Cocomaricopa-Bradshaw Trail; • Early settlement and rural development in present-day La Quinta and the Coachella Valley in general; • Transformation of the "cove communities," including La Quinta, from sparsely populated agrarian settlements to desert resort towns during the 20th century. RESEARCH METHODS RECORDS SEARCH On April 21, 2014, CRM TECH archaeologist Nina Gallardo (see App. 1 for qualifications) conducted the historical/archaeological resources records search at the Eastern Information Center (EIC), University of California, Riverside. During the records search, Gallardo examined maps and records on file at the EIC for previously identified cultural resources in or near the project area and 7 existing cultural resources reports pertaining to the vicinity. Previously identified cultural resources include properties designated as California Historical Landmarks, Points of Historical Interest, or Riverside County Landmarks, as well as those listed in the National Register of Historic Places, the California Register of Historical Resources, or the California Historical Resources Inventory. HISTORICAL RESEARCH Historical background research for this study was conducted by CRM TECH historian Bai "Tom" Tang (see App. 1 for qualifications) on the basis of published literature in local and regional history, and historic maps of the La Quinta area. Among maps consulted for this study were the U.S. General Land Office's (GLO) land survey plat maps dated 1856-1903 and the U.S. Geological Survey's (USGS) topographic maps dated 1904-1980. These maps are collected at the Science Library of the University of California, Riverside, and the California Desert District of the U.S. Bureau of Land Management, located in Moreno Valley. NATIVE AMERICAN PARTICIPATION On April 18, 2014, CRM TECH submitted a written request to the State of California's Native American Heritage Commission for a records search in the commission's sacred lands file. Following the Native American Heritage Commission's recommendations, CRM TECH further contacted 16 tribal representatives in the region in writing on April 23 to solicit local Native American input regarding any potential cultural resources concerns over the proposed project. The correspondences between CRM TECH and the Native American representatives are attached to this report in Appendix 2. FIELD SURVEY On April 30, 2014, CRM TECH archaeologist Daniel Ballester (see App. 1 for qualifications) carried out the intensive -level, pedestrian field survey of the project area. Most of the property was surveyed by walking a system of parallel north -south or east -west transects spaced 10-15 meters (approx. 33-50 feet) apart. Where the regular survey transects were impracticable, such as around the existing buildings and structures, Ballester remained as close to the courses of the transects as possible, and examined the exposed ground surface whenever possible. In this way, the ground surface in the entire project area was systematically and carefully examined for any evidence of human activities dating to the prehistoric or historic period (i.e., 50 years ago or older). Visibility of the native ground surface ranged from poor (0%) to good (approx. 80%) in the project area, depending upon the density of the vegetation and the presence of other ground cover, such as landscaping waste. RESULTS AND FINDINGS RECORDS SEARCH According to EIC records, the project area had not been surveyed for cultural resources prior to this study, and no cultural resources had been recorded on or adjacent to the property. Outside the project boundaries but within a one -mile radius, EIC records show more than 30 previous cultural resources studies covering various tracts of land and linear features, including the adjacent properties on all sides (Fig. 4). As a result of these and other similar studies in the vicinity, 24 historical/ archaeological sites were previously recorded within the scope of the records search, as listed in Table 1. In addition, 63 isolates—i.e., localities with fewer than three artifacts —were also recorded, consisting predominantly of ceramic sherds but including groundstone and chipped -stone artifacts as well. All but one of the isolates, a shotgun shell base, were prehistoric—i.e., Native American —in nature. None of these previously recorded sites or isolates was located in the immediate vicinity of the project area, and thus none of them requires further consideration during this study. HISTORICAL RESEARCH Historical sources consulted for this study suggest that the project area apparently remained unsettled and undeveloped through most of the historic period (Figs. 5-9). Between the 1850s and the early 1900s, the only man-made feature observed in the present-day La Quinta area was the historic Cocomaricopa-Bradshaw Trail, which skirted the foot of the Santa Rosa Mountains to the west of the project location (Figs. 5-7). Other than a foot trail along the course of today's Avenue 54, no man-made features were known to be present in or near the project area as late as 1941, Table 1.

By the 1950s, a building had appeared on the northern edge of the project area, beside Avenue 54 (Fig. 9). Between then and 1978, a larger building was constructed in the western portion of the project area, along with the pond that remain extant today (Fig. 2). In 1986, the property was acquired by famed musician, actor, and television host Mervyn Edward "Merv" Griffin, Jr., who used it as a second home and a ranch to raise racehorses (Palm Springs Life 2012; 2013). Most of the features now present on the property, including the lavish residence and the equestrian facilities, were built for Griffin over the next few years (ibid.). The latest addition among them, the racetrack in the southern portion of the project area, dates only to 2006 (Google Inc. 2006).

As it was completely redeveloped in the late 1980s under the Griffin ownership, the project area appears to be relatively low in sensitivity for cultural resources from the historic period. NATIVE AMERICAN PARTICIPATION In response to CRM TECH's inquiry, the Native American Heritage Commission reported in a letter dated April 18, 2014, that the sacred lands record search identified no Native American cultural resources within the project area, but recommended that local Native American groups be contacted for further information. For that purpose, the commission provided a list of potential contacts in the region. Upon receiving the NAHC's response, CRM TECH requested consultation with all 12 individuals on the referral list and the organizations they represent. In addition, as previously recommended by these tribal representatives or the appropriate tribal government staff, the following four individuals were also contacted: • Karen Kupcha of the Augustine Band of Cahuilla Indians; • Yvonne Markle, Environmental Office Manager for the Cahuilla Band of Indians; • John Gomez, Jr., Cultural Resources Coordinator for the Ramona Band of Cahuilla Indians; • Gabriella Rubalcava, Environmental Director for the Santa Rosa Band of Cahuilla Indians. 12 As of this time, two of the tribal representatives have responded in writing. Judy Stapp, Director of Cultural Affairs for the Cabazon Band of Mission Indians, replied in a letter dated April 30, 2014, stating that the tribe had no specific information on any sites of Native American traditional cultural value in the project area. On behalf of the Cabazon Band, Ms. Stapp deferred further consultation to the Torres Martinez Desert Cahuilla Indians (see App. 2). In a letter dated May 12, 2014, Patricia Garcia, Tribal Historic Preservation Officer for the Agua Caliente Band of Cahuilla Indians, noted that tribal records showed no previous cultural resources surveys covering the project area. Ms. Garcia requested copies of the records search results and all other cultural resource documentation generated from this project, and the presence of a professional Native American Cultural Resource Monitor during any ground -disturbing activities associated with the project (see App. 2). FIELD SURVEY The intensive -level field survey produced completely negative results for potential cultural resources. The entire project area was closely inspected for any evidence of human activities dating to the prehistoric or historic periods, but none was found. Besides the racetrack and the corrals, there are currently at least 11 buildings on the property, including residences, stables, garages, and gazebos, all of which appear consistent in age to the Griffin era in the property's ownership history, and are thus modern in origin (Fig. 10). No evidence was found of the buildings that were constructed on the property before 1978, as shown in the historic maps (Figs. 2, 9). Since their former sites are now occupied by modern buildings Figure 10. Modern features of the former Mery Griffin estate. Clockwise from top left: corral; stable; garage/storage building; residence. (Photos taken on April 30, 2014) 13 from the Griffin era, these older buildings were presumably demolished prior to the development of the Griffin estate. In short, no buildings, structures, objects, sites, features, or artifacts more than 50 years of age were encountered during the field survey, and the ground surface in the entire project area has been extensively disturbed as a result of past development, further reducing the property's potential sensitivity for buried cultural remains from the prehistoric or historic period. MANAGEMENT CONSIDERATIONS The purpose of this study is to identify any cultural resources within or adjacent to the project area, and to assist the City of La Quinta in determining whether such resources meet the official definition of "historical resources," as provided in the California Public Resources Code, in particular CEQA. According to PRC §5020.10), "`historical resource' includes, but is not limited to, any object, building, site, area, place, record, or manuscript which is historically or archaeologically significant, or is significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California." More specifically, CEQA guidelines state that the term "historical resources" applies to any such resources listed in or determined to be eligible for listing in the California Register of Historical Resources, included in a local register of historical resources, or determined to be historically significant by the Lead Agency (Title 14 CCR § 15064.5(a)(1)-(3)). Regarding the proper criteria for the evaluation of historical significance, CEQA guidelines mandate that "a resource shall be considered by the lead agency to be `historically significant' if the resource meets the criteria for listing on the California Register of Historical Resources" (Title 14 CCR § I5064.5(a)(3)). A resource may be listed in the California Register if it meets any of the following criteria: (1) Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage. (2) Is associated with the lives of persons important in our past. (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values. (4) Has yielded, or may be likely to yield, information important in prehistory or history. (PRC §5024.1(c)) A local register of historical resources, as defined by PRC §5020.1(k), "means a list of properties officially designated or recognized as historically significant by a local government pursuant to a local ordinance or resolution." For properties within the City of La Quinta, the City's Historic Preservation Ordinance (Title 7, La Quinta Municipal Code) provides for the establishment of a historic resources inventory as the official local register. A property may be considered for inclusion in the historic resources inventory based on one or more of the following: A. It exemplifies or reflects special elements of the city's cultural, social, economic, political, aesthetic, engineering or architectural history; or 14 B. It is identified with persons or events significant in local, state or national history; or C. It embodies distinctive characteristics of a style, type, period or method of construction, is a valuable example of the use of the indigenous materials or craftsmanship or is representative of a notable work of an acclaimed builder, designer or architect; or D. It is an archaeological, paleontological, botanical, geological, topographical, ecological or geographical site which has the potential of yielding information of scientific value; or E. It is a geographically definable area possessing concentration of sites, buildings, structures, improvements or objects linked historically through location, design, setting, materials, workmanship, feeling and/or association, in which the collective value of the improvements may be greater than the value of each individual improvement. (LQMC §7.06.020) The results of this study have established that no potential historical resources were previously recorded within or adjacent to the project area, and none was encountered during the present survey. The existing buildings, structures, and other features on the property, while demonstrating a clear connection to Mery Griffin, a prominent celebrity of the entertainment industry, are less than 30 years old today, falling far short of sufficient age to attain historic significance. Furthermore, as a second residence acquired by Griffin is his late years, the estate is not closely tied to his most distinguished professional accomplishments. As a modern creation that does not demonstrate extraordinary historical, architectural, or artistic merits, the former Griffin estate is not considered a potential "historical resource," as defined above. Based on these findings, the present study concludes that no historical resources exist within or adjacent to the project area. CONCLUSION AND RECOMMENDATIONS CEQA establishes that "a project that may cause a substantial adverse change in the significance of a historical resource is a project that may have a significant effect on the environment" (PRC §21084.1). "Substantial adverse change," according to PRC §5020.1(q), "means demolition, destruction, relocation, or alteration such that the significance of a historical resource would be impaired." In summary of the research results outlined above, no "historical resources," as defined by CEQA, were encountered throughout the course of this study. Therefore, CRM TECH presents the following recommendations to the City of La Quinta: No historical resources exist within or adjacent to the project area, and thus the project as currently proposed will not cause a substantial adverse change to any known historical resources. No further cultural resources investigation is necessary for the proposed project unless development plans undergo such changes as to include areas not covered by this study. If buried cultural materials are discovered during any earth -moving operations associated with the project, all work in that area should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds. 15 REFERENCES Bean, Lowell John 1978 Cahuilla.

RE: Sacred Lands File Search and Native American Contacts list for the 00Griffin Estate Project (CRM TECH #2805A);1 located in the City of La Quinta; Coachella Valley; Riverside County, California Dear Ms. Gallardo: A record search of the NAHC Sacred Lands Inventory failed to indicate the presence of Native American traditional cultural places of the Project site(s) or'areas of Potential effect' (APE), submitted to this office. Note also that the absence of archaeological resources does not preclude their existence at the subsurface level. In the 1985 Appellate Court decision (170 Cal App Td 604), the Court held that the NAHC has jurisdiction and special expertise, as a state agency, over affected Native American resources impacted by proposed projects, including archaeological places of religious significance to Native Americans, and to Native American burial sites. When the project becomes public, please inform the Native American contacts as to the nature of the project (e.g. residential, renewable energy, infrastructure or other appropriate type). Attached is a list of Native American tribes, Native American individuals or organizations that may have knowledge of cultural resources in or near the proposed project area (APE). As part of the consultation process, the NAHC recommends that local government and project developers contact the tribal governments and Native American individuals on the list in order to determine if the proposed action might impact any cultural places or sacred sites. If a response from those listed on the attachment is not received in two weeks of notification, the NAHC recommends that a follow-up telephone call be made to ensure the project information has been received. California Government Code Sections 65040.12(e) defines 'environmental justice' to provide "fair treatment of people... with respect to the development, adoption, implementation, and enforcement of environmental laws, regulations and policies."

The project area encompasses approximately 40 acres of previously developed land located along the south side of Avenue 54, between Madison Street and Monroe Street (at 81345 Avenue 54; APN 767-320-013). The project entails the construction of 78 single-family residences, but the existing estate home will remain on the property. The accompanying map, based on the USGS Indio, Calif., 7.5' quadrangle, depicts the location of the project area in Section 15, T6S R7E, SBBM. CRM TECH has been hired to conduct a cultural resource study, including the Native American scoping, for this project. In a letter dated April 18, 2014, the Native American Heritage Commission reports that the sacred lands record search identified no Native American cultural resources within the project area, but recommends that local Native American groups be contacted for further information. Therefore, as part of the cultural resources study for this project, I am writing to request your input on potential Native American cultural resources in or near the project area. According to records on file at the Eastern Information Center, located on the campus of the University of California, Riverside, there are no known historical/archaeological sites within the boundaries of the project area. However, at least 16 prehistoric sites and 64 prehistoric isolates have been recorded within a one -mile radius. The closest of these, Site 33-013753 (CA-RIV-7523), consisting of a temporary encampment, was located approximately 0.12 mile west of the project area. Three historic -period sites, including two refuse scatters and a single-family residence, have also been recorded within the one -mile radius. Lastly, one historic -period isolate has been recorded within the one -mile radius, consisting of an isolated shotgun shell base. Please respond at your earliest convenience if you have any specific knowledge of sacred/religious sites or other sites of Native American traditional cultural value within or near the project area that need to be taken into consideration as part of the cultural resources investigation. Any information or concerns may be forwarded to CRM TECH by telephone, e-mail, facsimile, or standard mail. Requests for documentation or information we cannot provide will be forwarded to our client and/or the lead agency, which is the City of La Quinta for CEQA-compliance purposes. We would also like to clarify that CRM TECH, as the cultural resources consultant for the project, is not the appropriate entity to initiate government -to -government consultations. Thank you for the time and effort in addressing this important matter. Respectfully, Nina Gallardo CRM TECH Email: ngallardo@crmtech.us April 30, 2014 Nina Gallardo CRM TECH 1016 E.

The project area is located within the boundaries of the ACBCI Reservation. A records check of the ACBCI registry indicates this area has not been surveyed for cultural resources. For this reason, the ACBCI THPO requests the folllowing: *The presence of an approved Native American Cultural Resource Monitor(s) during any ground disturbing activities (including archaeological testing and surveys). Should buried cultural deposits be encountered, the Monitor may request that destructive construction halt and the Monitor shall notify a Qualified Archaeologist (Secretary of the Interior's Standards and Guidelines) to investigate and, if necessary, prepare a mitigation plan for submission to the State Historic Preservation Officer and the Agua Caliente Tribal Historic Preservation Office *A copy of the records search with associated survey reports and site records from the information center. *Copies of any cultural resource documentation (report and site records) generated in connection with this project. Again, the Agua Caliente appreciates your interest in our cultural heritage. If you have questions or require additional information, please call me at (760)699-6907.

The project area consists of approximately 40 acres of land in Assessor's Parcel Number 767-320-013, occupied by an extensive residential compound with associated equestrian and other recreational facilities. It is located at 81-345 Avenue 54, between Madison Street and Monroe Street, in the northwest quarter of Section 15, T6S R7E, San Bernardino Baseline and Meridian. The study is part of the environmental review process for the Griffin Estates project, which proposes to subdivide of the property for single-family residential development while retaining the core of the existing residential compound. The City of La Quinta, as the lead agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA). The purpose of the study is to provide the City with the necessary information and analysis to determine whether the proposed project would potentially disrupt or adversely affect any significant paleontological resources, as mandated by CEQA. In order to identify any paleontological resource localities that may exist in or near the project area and to assess the possibility for such resources to be encountered in future excavation and construction activities, CRM TECH reviewed the results of previously completed records searches on the project vicinity, conducted a literature search, and carried out a systematic field survey of the project area, in accordance with the guidelines of the Society of Vertebrate Paleontology. Findings from these research procedures indicate that the project's potential to impact significant paleontological resources ranges from low in the disturbed surface soils to high, especially for Holocene -age invertebrate fossils, in the undisturbed Holocene Lake Cahuilla sediments that may be present under the ground surface. Based on these findings, CRM TECH recommends that a paleontological resource impact mitigation program be developed and implemented for the proposed project to prevent such impacts or reduce them to a level less than significant. The primary component of the mitigation program will be monitoring of ground disturbances during the project by qualified personnel. Since the surface soils have been extensively disturbed in the past, only periodic monitoring is recommended during demolition, tree removal, grubbing, or shallow surface grading. Deeper grading and excavations that impact the undisturbed subsurface soils, on the other hand, are likely to encounter paleontological resources within the Holocene Lake Cahuilla sediments. Therefore, continuous monitoring is recommended for any earth -moving operations that reach beyond the depth of two feet.

The project area consists of approximately 40 acres of land in Assessor's Parcel Number 767-320-013, occupied by an extensive residential compound with associated equestrian and other recreational facilities. It is located at 81-345 Avenue 54, between Madison Street and Monroe Street, in the northwest quarter of Section 15, T6S R7E, San Bernardino Baseline and Meridian (Fig. 2). The study is part of the environmental review process for the Griffin Estates project, which proposes to subdivide of the property for single-family residential development while retaining the core of the existing residential compound. The City of La Quinta, as the lead agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA; PRC §21000, et seq.). The purpose of the study is to provide the City with the necessary information and analysis to determine whether the proposed project would potentially disrupt or adversely affect any significant paleontological resources, as mandated by CEQA.

The following report is a complete account of the methods, results, and final conclusion of this study. PALEONTOLOGICAL RESOURCES DEFINITION Paleontological resources represent the remains of prehistoric life, exclusive of any human remains, and include the localities where fossils were collected as well as the sedimentary formations in which they were found. The defining character of fossils or fossil deposits is their geologic age, which is typically regarded as older than 10,000 years, the generally accepted temporal boundary marking the end of the last late Pleistocene glaciation and the beginning of the current Holocene epoch. Common fossil remains include marine shells; the bones and teeth of fish, reptiles, and mammals; leaf assemblages; and petrified wood. Fossil traces, another type of paleontological resource, include internal and external molds (impressions) and casts created by these organisms. These items can serve as important guides to the age of the rocks and sediments in which they are contained, and may prove useful in determining the temporal relationships between rock deposits from one area and those from another as well as the timing of geologic events. Fossil resources generally occur only in areas of sedimentary rock (e.g., sandstone, siltstone, mudstone, claystone, or shale). Because of the infrequency of fossil preservation, fossils, particularly vertebrate fossils, are considered to be nonrenewable paleontological resources. Occasionally fossils may be exposed at the surface through the process of natural erosion or as a result of human disturbances; however, they generally lay buried beneath the surficial soils. Thus, the absence of surface fossils does not preclude the possibility of their being present within subsurface deposits, while the presence of fossils at the surface is often a good indication that more remains may be found in the subsurface. SIGNIFICANCE CRITERIA According to guidelines proposed by Eric Scott and Kathleen Springer of the San Bernardino County Museum, paleontological resources can be considered to be of significant scientific interest if they meet one or more of the following criteria: 1. The fossils provide information on the evolutionary relationships and developmental trends exhibited among organisms, living or extinct; 2. 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 therein; 3. The fossils provide data regarding the development of biological communities or the interactions between paleobotanical and paleozoological biotas; 4. The fossils demonstrate unusual or spectacular circumstances in the history of life; and/or 3 5. 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. (Scott and Springer 2003:6) PALEONTOLOGICAL SENSITIVITY The fossil record is unpredictable, and the preservation of organic remains is rare, requiring a particular sequence of events involving physical and biological factors. Skeletal tissue with a high percentage of mineral matter is the most readily preserved within the fossil record; soft tissues not intimately connected with the skeletal parts, however, are the least likely to be preserved (Raup and Stanley 1978). For this reason, the fossil record contains a biased selection not only of the types of organisms preserved but also of certain parts of the organisms themselves. As a consequence, paleontologists are unable to know with certainty, the quantity of fossils or the quality of their preservation that might be present within any given geologic unit. Sedimentary units that are paleontologically sensitive are those geologic units (mappable rock formations) with a high potential to contain significant nonrenewable paleontological resources. More specifically, these are geologic units within which vertebrate fossils or significant invertebrate fossils have been determined by previous studies to be present or are likely to be present. These units include, but are not limited to, sedimentary formations that contain significant paleontological resources anywhere within their geographical extent as well as sedimentary rock units temporally or lithologically amenable to the preservation of fossils. A geologic formation is defined as a stratigraphic unit identified by its lithic characteristics (e.g., grain size, texture, color, and mineral content) and stratigraphic position. There is a direct relationship between fossils and the geologic formations within which they are enclosed, and with sufficient knowledge of the geology and stratigraphy of a particular area, it is possible for paleontologists to reasonably determine its potential to contain significant nonrenewable vertebrate, invertebrate, marine, or plant fossil remains. The paleontological sensitivity for a geologic formation is determined by the potential for that formation to produce significant nonrenewable fossils. This determination is based on what fossil resources the particular geologic formation has produced in the past at other nearby locations. Determinations of paleontologic sensitivity must consider not only the potential for yielding vertebrate fossils but also the potential for a few significant fossils that may provide new and significant taxonomic, phylogenetic, and/or stratigraphic data. The Society of Vertebrate Paleontology (1995:22-27) issued a set of standard guidelines intended to assist paleontologists to assess and mitigate any adverse effects/impacts to nonrenewable paleontological resources. The Society defined three potential categories of paleontological sensitivity for geologic units that might be impacted by a proposed project. These categories are described below, along with the criteria used to establish their sensitivity. High sensitivity: Geologic units assigned to this category are considered to have a high potential for significant nonrenewable vertebrate, invertebrate, marine, or plant fossils. Sedimentary rock I] units in this category contain a relatively high density of recorded fossil localities, have produced fossil remains in the vicinity, and are very likely to yield additional fossil remains. • Low sensitivity: Geologic units are assigned to this category when they have produced no or few recorded fossil localities and are not likely to yield any significant nonrenewable fossil remains. • Undetermined sensitivity: Geologic units are assigned to this category when there is limited exposure of the rock units in the area and/or the rock units have been poorly studied. SETTING The project area is located in the Coachella Valley, which occupies the northwestern portion of the Colorado Desert Geomorphic Province (Jenkins 1980:40-41; Harden 2004:63-64; Harms 1996:iii). The Colorado Desert Province is bounded on the southwest side by the Peninsular Ranges Province, on the north by the eastern Transverse Ranges Province, and on the northeast by the southern portion of the Mojave Desert Province (ibid.). The province widens to the southeast through the Imperial Valley and into Mexico. One of the major features within the Colorado Desert province is the Salton Trough, a 290-km- long (approx. 180 miles) structural depression containing the present-day Salton Sea and extending from the San Gorgonio Pass area southward into Mexico. During the late Miocene and early Pliocene, this trough was a northward extension of the Gulf of California (Powell 1995). By late Pleistocene and Holocene times, the northwestern portion of this trough was filled with over 4,000 feet of sediments (Proctor 1968). While the term "Salton Trough" refers to the entire structural depression from the San Gorgonio Pass to the Gulf of California, the term "Salton Basin" is used to describe that portion of the area that drains directly into the Salton Sea (Harms 1996:117). The Salton Sea, therefore, occupies the Salton Basin portion of the Salton Trough (ibid.). The Salton Trough was once the location of a much larger freshwater lake, known as Holocene Lake Cahuilla, that formed when water from the Colorado River flowed into the basin directly and then back out through Baja California to the Gulf of California (Waters 1983). Holocene Lake Cahuilla occupied a much larger portion of the Salton Basin than that of the present-day Salton Sea (Rogers 1965). The shoreline of the last ancient lake to fill the basin can be seen today as a line along the base of the Santa Rosa Mountains at an elevation of about 42 feet above sea level (Waters 1983; Wilke 1978). Along some portions of this shoreline, tufa was deposited on the rocky areas. This tufa was radiometrically dated as Late Pleistocene through early Holocene (Smith and Turner 1975:24-25; Turner and Reynolds 1977). However, it appears that these dates are too old and that the entire tufa sequence is more likely of Holocene age (Quinn 2000:5-6). Elevations within the Colorado Desert province tend to be low, while those of the adjacent provinces can be quite high. This configuration has made for local to regional rapid filling of the basin, especially along its margins, with coarse clastic sediments. Such coarse sediments afford only local environments for the preservation of vertebrate remains. However, some scattered vertebrate fossils have been found in these fluvial -derived clastic sediments. 5 Figure 3. Typical landscapes within the project area. Clockwise from left: view to the south across the equestrian race track; landscaping waste; existing buildings; shell deposits in the surface soils. (Photos taken on April 30, 2014) As mentioned above, the project area is occupied by a number of buildings and other facilities of the former Mery Griffin estate, including the main residence, guesthouses, gazebos, and a pond in the northwestern portion, stables and corrals in the northeastern portion, and an equestrian racetrack in the southern portion (Fig. 3). Elevations on the property range around 10-20 feet below mean sea level, and the terrain is relatively level with a slight incline to the northwest. Soils consist of light grey fine sands mixed with freshwater shells, and the vegetation observed in the project area includes both introduced landscaping plants and some native vegetation, such as palms, palo verdes, tamarisks, eucalyptuses, pepper trees, and small desert shrubs and grasses (Fig. 3). METHODS AND PROCEDURES RECORDS SEARCHES The records search service was provided by the San Bernardino County Museum in Redlands and the Natural History Museum of Los Angeles County in Los Angeles, originally for the adjacent griffin Ranch project in 2004. These institutions maintain files of regional paleontological localities as well as supporting maps and documents. The records search results were used to identify any known paleontological localities within the project area or in the general vicinity. LITERATURE REVIEW In addition to the records searches, a literature search was conducted using materials in the CRM TECH library, including unpublished reports produced during surveys of other properties in the area, n and the personal library of CRM TECH geologist/paleontologist Harry M. Quinn, California Professional Geologist #3477 (see App. 1 for qualifications). FIELD SURVEY On April 4, 2014, CRM TECH paleontological surveyor Daniel Ballester (see App. 1 for qualifications) carried out the intensive -level, pedestrian field survey of the project area under the direction of Harry M. Quinn. Most of the property was surveyed by walking a system of parallel north -south or east -west transects spaced 10-15 meters (approx. 33-50 feet) apart. Where the regular survey transects were impracticable, such as around the existing buildings and structures, Ballester remained as close to the courses of the transects as possible, and examined the exposed ground surface whenever possible. In this way, the ground surface in the entire project area was systematically and carefully examined to determine the soil types, to verify the geological formations, and to look for any indications of paleontological remains. Visibility of the native ground surface ranged from poor (0%) to good (approx. 80%) in the project area, depending upon the density of the vegetation and the presence of other ground cover, such as landscaping waste. RESULTS AND FINDINGS RECORDS SEARCHES The Natural History Museum of Los Angeles County and the San Bernardino County Museum found no known paleontological localities within or in the immediate vicinity of the project area (McLeod 2004; Scott 2004; see App. 2). However, several paleontological localities have been reported nearby from sediment lithologies similar to those known to occur in the subsurface at this location, specifically the Lake Cahuilla beds of late Pleistocene or Holocene age (ibid.). These alternating lacustrine and fluvial deposits have produced diverse freshwater fossil remains (ibid.). Based on these previous discoveries, the San Bernardino County Museum considers the project vicinity to be an area of "high paleontologic sensitivity," and declares ground -disturbing operations within undisturbed Lake Cahuilla beds to have a "high potential to impact significant nonrenewable fossil resources," primarily Holocene -age lacustrine fossils (Scott 2004). The Natural History Museum also notes that older Quaternary deposits at some depth beneath the uppermost soil levels may contain significant fossil remains (McLeod 2004). LITERATURE REVIEW The surface sediments in the project area was mapped by Dibblee (1954:Plate 3) as Qal, namely Recent alluvial -fan, flood -plain, swamp, lake, and sand dune deposits. Rogers (1965) mapped the surface sediments in the project area as Ql-Qal, or Quaternary lake deposits and alluvium of Recent (Holocene) origin. Later, Dibblee (2008) mapped the surface geology as Qa, or alluvial sand and 7 clay of valley areas. Based on these mappings, the project area is located within the lakebed of Holocene Lake Cahuilla during its last high stand. The surface soils within the project area have been mapped by Knecht (1980:Sheet 12) as entirely CpA. The CpA-type soils belong to the Coachella Series, specifically the Coachella fine sand, 0-2% slopes, and form on alluvial fans and flood plains (ibid.:16). FIELD SURVEY During the field survey, freshwater shells and shell fragments, primarily of Physa sp., Tryonia sp., Anodonta sp. and Gyraulus sp., were observed on the ground surface throughout the project area. No fish or other vertebrate remains were present. It was noted during the survey that the ground surface in the entire project area has been extensively disturbed as a result of past development activities, most notably the construction of the existing residential compound, a large pond, the equestrian facilities, and other associated structures and features. SUMMARY The results of the records searches, literature research, and field survey indicate that the project area may contain sediments deposited within the bed of the Holocene Lake Cahuilla, from which many Holocene paleontological localities are known to have been found, including some near the project location. Specimens from these localities usually consist only of freshwater mollusks from the Holocene Lake Cahuilla. However, other invertebrates have been found in association with the vertebrate remains of fish, birds, reptiles, and amphibians (McLeod 2004; Scott 2004). Some plant spores and pollens have also discovered (ibid.). CONCLUSION AND RECOMMENDATIONS CEQA Appendix G provides that "a project may be deemed to have a significant effect on the environment if it will ... disrupt or adversely affect a ... paleontological site except as a part of a scientific study." The present study, conducted in compliance with this provision, is designed to identify any significant, non-renewable paleontological resources that may exist within or adjacent to the project area, and to assess the possibility for such resources to be encountered in future excavation and construction activities. The results of the various research procedures completed during this study suggest that the extensively disturbed surface soils in the project area appear to be low in sensitivity for potentially significant paleontological remains. However, undisturbed Holocene Lake Cahuilla sediments may be present under the ground surface, and these sediments are considered high in paleontological sensitivity, especially for Holocene -age invertebrate fossils. Based on these findings, CRM TECH recommends that a paleontological resource impact mitigation program be developed and implemented for the proposed project to prevent such impacts or reduce them to a level less than significant. The primary component of the mitigation program will be monitoring of ground disturbances during the project by qualified personnel. Since the surface soils have been extensively disturbed in the past, only periodic monitoring is recommended during demolition, tree removal, grubbing, or shallow surface grading. Deeper grading and excavations that impact the undisturbed subsurface soils, on the other hand, are likely to encounter paleontological resources within the Holocene Lake Cahuilla sediments. Therefore, continuous monitoring is recommended for any earth -moving operations that reach beyond the depth of two feet. The mitigation program should be developed in accordance with the provisions of CEQA as well as the proposed guidelines of the society of Vertebrate Paleontology, and should include but not be limited to the following: 1. The excavation of areas identified as likely to contain paleontologic resources, such as the undisturbed Lake Cahuilla beds and any undisturbed subsurface older alluvium, should be monitored by a qualified paleontological monitor. The monitor should be prepared to quickly salvage fossils, if they are unearthed, to avoid construction delays, but must have the power to temporarily halt or divert construction equipment to allow for removal of abundant or large specimens. 2. Samples of sediments should be collected and washed to recover small invertebrate and vertebrate fossils. 3. Recovered specimens should be identified and curated at a repository with permanent retrievable storage that would allow for further research in the future. 4. A report of findings, including, when appropriate, an itemized inventory of recovered specimens and a discussion of their significance, should be prepared upon completion of the steps outlined above. The report and inventory, when submitted to the appropriate lead agency, would signify completion of the program to mitigate impacts on paleontologic resources. E REFERENCES Dibblee, T.

McKERNAN Director re: PALEONTOLOGY REVIEW, "1518: APNs 767-320-001, -002, -004 AND -01311, CITY OF LA QUINTA, RIVERSIDE COUNTY, CALIFORNIA Dear Laura, The Division of Geological Sciences ofthe San Bernardino County Museum (SBCM) has completed a literature review and records search for the above -referenced —196-acre development in the City of La Quinta, Riverside County, California. The proposed study area is located in the northern half of section 15, Township 6 South, Range 7 East, San Bernardino Base and Meridian, as seen on the Indio, California and the La Quinta, California 7.5' United States Geological Survey topographic quadrangle maps (1956 and 1959 editions, photorevised 1972 and 1980, respectively). The study area lies within the Salton Trough, a northward extension of the Sea of Cortez (McKibben, 1993). The Salton Trough lies below sea level, and is an active continental rift underlain by the landward extension of the East Pacific Rise; it is surrounded on three sides by mountains and bounded to the southeast by the Colorado River delta. Since the beginning of the Holocene Epoch [± 11,000 years before present (ybp)], the Colorado River delta has blocked marine water from entering the Salton Trough from the Sea of Cortez. Freshwater lakes have existed intermittently in the deeper parts of the basin that developed landward of the Colorado River delta (Van de Kamp, 1973; Waters, 1983; Maloney, 1986; Whistler and others, 1995). Previous geologic mapping of the La Quinta region by Rogers (1965) indicates that the study area is located upon Quaternary lake sediments deposited below the 12-meter high shoreline of ancient Lake Cahuilla, which is thought to have existed intermittently from 470 ybp to at least ± 6,000 ybp (Van de Kamp, 1973; Waters, 1983; Whistler and others, 1995). These sediments were deposited during each of at least seven high stands of Lake Cahuilla, each high stand resulting from flooding of the Salton Trough by inflow from the Colorado River (Waters, 1983). Fluvial sediments in the area were laid down during intervening lake low stands when the lake bed was dry. These alternating lacustrine and fluvial sediments, termed the Lake Cahuilla beds, have previously yielded fossil remains representing diverse freshwater diatoms, land plants, sponges, ostracods, molluscs, fish, and small terrestrial vertebrates. As these remains are not associated with any evidence of human activity, they are considered paleontological rather than archaeological. For this reason, the Lake Cahuilla beds are interpreted to have high potential to contain nonrenewable fossil resources. County Administrative Officer Board of Supervisors NORMAN A.

Economic Development and s :SIE GONZALES _ ..R��E'I'V Cb UCCt2 S 2004 Public Services Group Literature / records review, Paleontology, CRM Tech: La Quinta properties 2 For this review, I conducted a search of the Regional Paleontologic Locality Inventory (RPLI) at the SBCM. The results of this records search indicated that no paleontologic localities are recorded within the boundaries of, or within one mile of, the proposed property. However, Whistler and others (1995) discussed paleontologic resource localities from near the proposed study area that have produced fossils from sediment lithologies mapped (Rogers, 1965) as similar to those present at depth within the boundaries of the proposed property. Five sampling sites yielded diatoms, land plants, sponges, molluscs, ostracods, bony fish, reptiles, birds and small mammals (Whistler and others, 1995). The lowest stratigraphic unit in this region was radiometrically dated to 5,890 ± 60 ybp, which indicated a high stand of ancient Lake Cahuilla older than any described previously. These sites are mapped (Whistler and others, 1995) as within approximately 1 mile or less west of the proposed property; however, this mapping is diagrammatic and the precise location of these sites cannot be determined from the published account. It is recommended that the locality records of the Vertebrate Paleontology Department of the Natural History Museum of Los Angeles County be reviewed for more detailed information on these sites. Recommendations The results of the literature review and the check of the RPLI at the SBCM demonstrate that excavation for the proposed property in the City of La Quinta has high potential to impact significant nonrenewable fossil resources. This property is therefore assigned high paleontologic sensitivity. A qualified vertebrate paleontologist must therefore develop a program to mitigate impacts to nonrenewable paleontologic resources. This mitigation program should be consistent with the provisions of the California Environmental Quality Act (Scott and Springer, 2003), as well as with regulations currently implemented by the County of Riverside and the proposed guidelines of the Society of Vertebrate Paleontology. This program should include, but not be limited to: 1. Monitoring of excavation in areas identified as likely to contain paleontologic resources by a qualified paleontologic monitor. Based upon the results of this review, areas of concern include any undisturbed surface or subsurface sediments of the Lake Cahuilla beds. Paleontologic monitoring is recommended only for those undisturbed sediments wherein fossil plant or animal remains are found with no associated evidence of human activity or an archaeological context. Should archaeological materials or other evidence of human presence be encountered, sites yielding this evidence should be treated as archaeological rather than as paleontological. Paleontologic monitors should be equipped to salvage fossils as they are unearthed to avoid construction delays, and to remove samples of sediments that are likely to contain the remains of small fossil invertebrates and vertebrates. Monitors must be empowered to temporarily halt or divert equipment to allow removal of abundant or large specimens. Monitoring may be reduced if the potentially-fossiliferous units described herein are not present, or if present are determined upon exposure and examination by qualified paleontologic personnel to have low potential to contain fossil resources. Literature / records review, Paleontology, CRM Tech: La Quinta properties 3 2. Preparation of recovered specimens to a point of identification and permanent preservation, including washing of sediments to recover small invertebrates and vertebrates. 3. Identification and curation of specimens into an established, accredited museum repository with permanent retrievable paleontologic storage (e.g., SBCM). The paleontologist must have a written repository agreement in hand prior to the initiation of mitigation activities. Mitigation of adverse impacts to significant paleontologic resources is not complete until such curation into an established museum repository has been fully completed and documented. 4. Preparation of a report of findings with an appended itemized inventory of specimens. It is recommended that this report incorporate the full results of this literature review. The report and inventory, when submitted to the appropriate Lead Agency along with confirmation of the curation of recovered specimens into an established, accredited museum repository, would signify completion of the program to mitigate impacts to paleontologic resources.

We do not have any vertebrate fossil localities that lie directly within the proposed project boundaries, but we do have localities nearby from the same deposits that occur as subsurface units in the proposed project area. Below the uppermost soil layers, that are unlikely to contain significant vertebrate fossils, the entire project area has surficial lacustrine and fluvial [lake and stream channel] deposits of Late Pleistocene or Holocene age [the latter less than 10,000 years before present] known as the Lake Cahuilla beds. Almost directly south of the western portion of the proposed project area on both sides of Madison Street north of 58t' Avenue but slightly lower in elevation, we have several fossil localities in the same continuous Lake Cahuilla beds. These localities were collected during mitigation activities for the construction of the PGA West Tom Weiskopf Signature Golf Course. LACM 6252, 6253, and 6255 were collected in a single trench site west of Madison Street. They produced a significant fauna of terrestrial and freshwater vertebrates (see attachment) as well as diatoms, land plants, clams, snails and crustaceans. A trench to the east of Madison Street produced a similar fauna so was not collected. A single jaw of the bighorn sheep Ovis canadensis was recovered from LRCM 6256, another locality to the east of Madison Street. Any significant subsurface below the uppermost soil layers may well encounter significant fossil remains from the Quaternary Lake Cahuilla beds. Many of the fossil specimens collected from these deposits are small isolated elements of fossil organisms that were recovered from screen - washing sediment samples. Thus if any significant excavation below the soil level is conducted on 900 Exposition Boulevard Los Angeles, CA 90007 RECEIVED DEC 2 3 2004 the proposed project site, it is recommended that in addition to monitoring the excavations to collect any larger fossil remains uncovered, sediment samples be collected and processed to determine the small fossil potential at the proposed project site. Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations. Additional fossil locality information for the proposed project area may be available through the University of California at Riverside Department of Geology [collections and records now at the University of California at Berkeley Museum of Paleontology]. This records search covers only the vertebrate paleontology records of the Natural History Museum of Los Angeles County. It is not intended to be a thorough paleontological survey of the proposed project area covering other institutional records, a literature survey, or any potential on -site survey.
