MEMORANDUM

DATE: August 9, 2018

TO: Pamela Reading, Principal

FROM: Ivan H. Strudwick, RPA, Associate

SUBJECT: Cultural Resources Technical Memorandum for the Santa Maria Department of Motor Vehicles Field Replacement Project in Santa Maria, Santa Barbara County, California (LSA Project No. DGS1701)

LSA conducted a cultural resources study for the Santa Maria Department of Motor Vehicles (DMV) Field Replacement Project (Project) in Santa Maria, Santa Barbara County, California. Current plans for the Project include the construction of a single-story building on the south side of the Project site, with parking to the north and east. As proposed, the Project will include 98 car parking stalls, including four electric/alternative fuel efficient spaces. The Project will also include eight motorcycle parking spaces, one semi-truck and trailer parking space, and one delivery truck parking space. A bicycle rack will be provided on the northwest side of the building. The drive test lane and motorcycle skills testing area will be located in the southwest corner of the Project site. The Project also proposes decorative fencing around the perimeter of the Project and decorative sliding security gates at the vehicular entrances. Utility installation will include a water distribution system; gas, electric, and telephone system hook ups; site lighting; and installation of a storm water collection system. Project construction is expected to take approximately 16 months, and is scheduled to start in the spring of 2020 and end in the fall of 2021.

The purpose of the study, in accordance with the California Environmental Quality Act (CEQA), is to (1) identify cultural resources that may meet the definition of historical or unique archaeological resources per CEQA (Public Resources Code [PRC] Sections 21084.1 and 21083.2); (2) identify human remains; and (3) recommend procedures for the mitigation of potential impacts to such resources/remains, if necessary. The study consisted of background research; tribal outreach, including a review of the Sacred Lands File (SLF) maintained by the California Native American Heritage Commission (NAHC); and an archaeological field survey of the Project site. LSA Cultural Resources Manager Kerrie Collison, Registered Professional Archaeologist (RPA) 28731436, conducted the archaeological field survey and LSA Associate Archaeologist Ivan H. Strudwick, RPA 10350, prepared the technical memorandum.

PROJECT SITE The approximately 3-acre Project site is located within the Santa Maria City limits, approximately 1 mile northeast of the Santa Maria Public Airport, 0.8 miles west of U.S. Route 101, and 0.2 miles east

2

of State Route 135. The Project site, currently vacant, is situated with Santa Maria Way to the west, Sunrise Drive to the south, vacant land to the east, and a bicycle path to the north, which connects Santa Maria Way to Miramonte Park. It is located on the United States Geological Survey (USGS) Santa Maria, California 7.5-minute topographic quadrangle in the northwest quarter of Township 10 North, Range 34 West, Section 35, San Bernardino Baseline and Meridian (USGS 1982; Attachment A).

BACKGROUND RESEARCH

LSA conducted background research to identify cultural resources within, and cultural resource studies of, the Project site. The background research included a record search conducted by staff at the Central Coastal Information Center (CCIC), an affiliate of the State of California Office of Historic Preservation (OHP) located at University of California, Santa Barbara. The CCIC is the official State repository of cultural resources records and reports for Santa Barbara County. On May 3, 2018, the records search was completed for the Project site and a 0.5-mile search radius. Background research also included a review of historical topographic maps and aerial photographs to assess the potential for subsurface historic-period archaeological deposits at the Project site, and a review of the following State and federal inventories:

• Directory of Properties in the Historic Property Data File (California OHP April 5, 2012). The directory includes the listings of the National Register of Historic Places, National Historic Landmarks, the California Register of Historical Resources (California Register), California Historical Landmarks, and California Points of Historical Interest;

• California Historical Landmarks (California OHP 1996);

• California Points of Historical Interest (California OHP 1992);

• Five Views: An Ethnic Historic Site Survey for California (California OHP 1988); and

• California Inventory of Historic Resources (California Department of Parks and Recreation 1976).

Background Research Results

The CCIC database indicates that there are no recorded cultural resources within the Project site, and no previously-recorded cultural resources are within 0.5 miles of the Project site. One previous cultural resources study covers the entire Project site (Spanne 1978), and two studies have been conducted within approximately 0.25 miles of the Project site (Attachment B).

Background research included a review of historical topographic maps and aerial photographs to assess the potential for subsurface historic-period archaeological deposits at the Project site.1 The oldest available aerial photograph for the Project site dates to 1967. This aerial shows open land and dirt roads surrounding a building in the northern end of the Project site. The building appears to have been demolished sometime between 2005 and 2009; however, concrete pads (which likely

3

functioned as the building foundation) were left in place after the building was torn down. These concrete pads are still visible in the 2014 aerial photographs.

The historical topographic map from 1954 identifies a single well in the southwestern portion of the Project site. The well also appears on maps dated to 1960, 1961, 1968, 1975, 1977, 1983, and 1985, but does not appear on the 2012 topographic map. The historical topographic map from 1960 indicates the presence of two buildings in the same location where the aerial photographs show the existing concrete pads. The buildings appear on historical topographic maps dated to 1960, 1961, 1968, 1975, 1977, 1983, and 1985, but do not appear on the 2012 topographic map.

The well and buildings appear to be the only evidence of development within the Project site. However, the remainder of the Project site has also been subject to disturbance, as all available historical aerial photographs depict either dirt roads or vehicle tire tracks throughout the Project site.

NATIVE AMERICAN CONSULTATION As required under CEQA, specifically PRC 21080.3.1 and Chapter 532 Statutes of 2014 (i.e., Assembly Bill [AB] 52), Native American consultation is required for any CEQA project that has a Notice of Preparation, a Notice of Negative Declaration, or a Mitigated Negative Declaration filed on or after July 1, 2015. On April 18, 2018, LSA sent an email to the NAHC on behalf of California DMV requesting a review of the SLF to determine the potential presence of Native American cultural resources that might be affected by the proposed Project. The NAHC maintains this database and is the official State repository of Native American sacred site location records in California.

Native American Consultation Results

Mr. Frank Lienert, NAHC Associate Governmental Program Analyst, responded via email on April 30, 2018, stating that a records search of the SLF was completed with negative results. Mr. Lienert also provided a suggested list of Native American individuals to contact for information regarding the Project site. The DMV has assumed responsibility for conducting consultation per AB 52.

FIELD SURVEY On May 22, 2018, LSA Archaeologist Kerrie Collison, M.A., RPA, conducted a pedestrian survey of the Project site. The survey was completed in east-west transects spaced less than 5 meters apart. Ground surface visibility throughout the Project site varied from less than 25 percent in places where grasses were present, to approximately 75 percent in open areas with less vegetation. A trowel was used to periodically clear vegetation in order to obtain better ground visibility, and rodent backdirt was examined for precontact and historic-period cultural material.

Field Survey Results

The Project site is at a slightly lower elevation than the streets that border it, and is mostly flat, with a few gently-sloped areas. Modern trash was lightly scattered throughout the Project site, and vehicles have recently transited the area. Rodent burrows were present throughout the site. The soil was light brown, very fine, and dry. Concrete pads were present towards the northern edge of the

4

Project site (Attachment C). These pads are the foundations of the buildings that were demolished between 2005 and 2009, and were recorded as site P-42-004143.

P-42-004143

Site P-42-004143 measures approximately 124 feet north/south by 218 feet east/west and consists of concrete pads of various sizes and shapes. Historical aerial photographs indicate that the pads were the foundations of buildings that were constructed before 1967. The associated buildings were demolished between 2005 and 2009, and the concrete pads are their only remnants. Additional concrete building pads, likely constructed around the same time, are located to the east, and outside of, the Project site and were not formally recorded. However, the additional concrete pads were mapped for the site record using aerial photographs (Attachment D). The lack of documentation about the buildings that previously stood on-site suggests a lack of association with significant historical events or persons. Additionally, the pads are isolated features with no apparent associated features or constituents, and do not have the potential to yield information important to history due to a lack of integrity. Any limited data potential the pads may have had was realized by their recording on California Department of Parks and Recreation 523 series forms.

Following initial recordation of P-42-004143, a Phase I Environmental Site Assessment was obtained for an area that includes P-42-004143 (Avocet 2016). According to this Phase I report, a residence and water well (the buildings constructed “before 1967,” as referenced on the original site record) were present during the 1950s in what is now P-42-004143. Also according to the Phase I, the small/medium sized commercial buildings that previously existed on the property were constructed between 1994 and 2005; these are the buildings associated with the existing concrete foundations that make up P-42-004143. The Phase I states that the existing concrete pads are foundations typical of the slab-on-grade construction that is characteristic of low-rise commercial/industrial buildings (Avocet 2016).

As such, the concrete building foundations of P-42-004143 are associated with commercial buildings that were built between 1994 and 2005. For the reasons presented above, P-42-004143 does not appear eligible for inclusion in the California Register and is not a historical resource per CEQA.

SUMMARY AND RECOMMENDATIONS The study consisted of a records search, SLF search, and field survey. The records search was negative for the presence of cultural resources in the Project site, as was the SLF search. The field survey identified one cultural resource (P-42-004143), a set of concrete pads that functioned as building foundations, within the Project site. However, the site does not appear eligible for inclusion in the California Register and is not a historical resource per CEQA. The Project site has been subject to a high level of surface and subsurface disturbance since at least 1967 due to the presence of a well and buildings. While the land currently appears undeveloped, the prior disturbance of the land is evidenced through historical aerial photographs and topographic maps. However, because only one previous cultural resources study has addressed the Project site (Spanne 1978), only two studies have been conducted within 0.25 miles of the Project, and none of these studies have involved subsurface testing, the archaeological sensitivity of the Project site and immediate vicinity is moderate.

Post-survey research regarding geotechnical studies of the Project site revealed the following information. Geocon’s (2017) exploratory geotechnical borings on the Project site revealed that the southern portion of the area and the majority of the proposed new building footprint is underlain with undocumented fill. The fill, where present, extends to a depth of approximately 3.5 feet and consists of loose, silty sand with some gravel (Geocon 2017: 2). Below the fill and throughout the rest of the Project site, sediment consists of older dune sand that extends to a depth of approximately 51 feet. Diblee (1994) temporally assigns the older dune sand in the Project site to the early Holocene, which Walker et al. (2012) date to approximately 8,200 to 11,700 years before present (B.P.). This time period includes potential human occupation of the Project site, and it is possible that the proposed Project will impact previously unrecorded archaeological deposits that may be considered historical or unique archaeological resources per CEQA (PRC Sections 21084.1 and 21083.2).

For the above reasons, LSA recommends the following mitigation measures:

CULT-1: Archaeological Monitoring. Prior to the start of ground-disturbing construction activities, the Department of General Services (DGS) shall retain a qualified archaeologist to provide professional archaeological monitoring services for any construction activities that may disturb native soils. The archaeologist shall prepare a monitoring plan that includes: (1) a description of the circumstances that would result in the halting of work at the project site (e.g., what is considered a “significant” archaeological site); (2) a description of procedures for halting work on site and notification procedures; and (3) a description of monitoring reporting procedures. An archaeological monitor shall be present at the pre-grading conference in order to explain the cultural monitoring requirements associated with the proposed Project. If any significant archaeological resources are found during monitoring, work shall stop within the immediate vicinity (precise area to be determined by the archaeologist in the field) of the resource until such time as the resource can be evaluated by an archaeologist and any other appropriate individuals. Project personnel shall not collect or move any archaeological materials and associated materials. To the extent feasible, project activities shall avoid these deposits. Where avoidance is not feasible, the archaeological deposits shall be evaluated for their eligibility for listing in the California Register of Historic Places. If the deposits are not eligible, avoidance is not necessary. If the deposits are eligible, adverse effects on the deposits must be avoided, or such effects must be mitigated. Mitigation can include, but is not necessarily limited to: excavation of the deposit in accordance with a data recovery plan (see CCR §15126.4(b)(3)(C)) and standard archaeological field methods and procedures; laboratory and technical analyses of recovered archaeological materials; production of a report detailing the methods, findings, and significance of the archaeological site and associated materials; curation of archaeological materials at an appropriate facility for future research and/or display; an interpretive display of recovered archaeological materials at a local school, museum, or library; and public lectures at local schools and/or historical societies on the findings and significance of the site and recovered

6

archaeological materials. Disposition of the resources shall be at the discretion of DGS, but in accordance with the foregoing.

CULT-2: Human Remains. In the event that human remains are encountered on the Project site, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately consistent with the requirements of California Code of Regulations (CCR) §15064.5(e). State Health and Safety Code §7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to Public Resources Code (PRC) §5097.98. If the remains are determined to be Native American, the County Coroner shall notify the Native American Heritage Commission (NAHC), which shall determine and notify a Most Likely Descendant (MLD). With the permission of the landowner or his/her authorized representative, the MLD may inspect the site of the discovery. The MLD shall complete the inspection and make recommendations or preferences for treatment within 48 hours of being granted access to the site. The MLD recommendations may include scientific removal and nondestructive analysis of human remains and items associated with Native American burials, preservation of Native American human remains and associated items in place, relinquishment of Native American human remains and associated items to the descendants for treatment, or any other culturally appropriate treatment. Consistent with CCR §15064.5(d), if the remains are determined to be Native American and an MLD is notified, DMV shall consult with the MLD as identified by the NAHC to develop an agreement for treatment and disposition of the remains. Prior to the issuance of grading permits, the California Department of Motor Vehicles, or designee, shall verify that all grading plans specify the requirements of CCR §15064.5(e), State Health and Safety Code §7050.5, and PRC §5097.98, as stated above.

Implementation of the above mitigation measures will ensure that Project impacts to cultural resources will be mitigated to a level that is less than significant.

Following recordation of P-42-004143, a Phase I Environmental Site Assessment (prepared by Avocet Environmental, Inc. in November 2016 for California Department of General Services) was obtained for an area that includes P-42-004143. According to this Phase I report, a residence and water well (the buildings constructed “before 1967,” as referenced on the original site record) were present during the 1950s in what is now P-42-004143. Also according to the Phase I, the small/medium sized commercial buildings that previously existed on the property were constructed between 1994 and 2005; these are the buildings associated with the existing concrete foundations that make up P-42-004143. The Phase I states that the existing concrete pads are foundations typical of the slab-on-grade construction that is characteristic of low-rise commercial/industrial buildings. As such, the concrete building foundations of P-42-004143 are associated with commercial buildings that were built between 1994 and 2005. P-42-004143 has now been determined not old enough to be considered historical resource and does not warrant further documentation or investigation as it is not extraordinary or unique.

MEMORANDUM

DATE: August 27, 2018

TO: Pam Reading, Principal, LSA

FROM: Sarah Rieboldt, Ph.D., Senior Paleontological Resources Manager, LSA

SUBJECT: Paleontological Resources Technical Memorandum for the Santa Maria Department of Motor Vehicles Field Office Replacement Project, Santa Maria, Santa Barbara County, California

INTRODUCTION This memorandum was prepared to ensure that the Santa Maria Department of Motor Vehicles (DMV) Field Office Replacement Project (proposed Project), in Santa Maria, California, is in compliance with all applicable State regulations, as well as guidelines of the Society of Vertebrate Paleontology (SVP, 2010). The applicable regulations include the California Environmental Quality Act (CEQA), Public Resources Code (PRC) Division 13, Chapter 2.6; the State CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, Appendix G; and PRC 5097.5). This memorandum addresses the potential for the proposed Project to impact paleontological resources and, if needed, includes mitigation measures and other recommendations to minimize these impacts. The Department of Motor Vehicles is the Lead Agency under CEQA.

PROJECT LOCATION AND DESCRIPTION The proposed Project is approximately 1 mile northeast of the Santa Maria Public Airport, 0.8 mile west of United States Route 101, and 0.2 mile east of State Route 135 on the northeast corner of Santa Maria Way and Sunrise Drive, 2770 Santa Maria Way (Assessor Parcel Number 109-010-029]. The Project site is depicted on the United States Geological Survey (USGS) Santa Maria, California 7.5-minute topographic quadrangle map in Township 10 North, Range 34 West, Section 35, San Bernardino Baseline and Meridian (USGS, 1982; Figure 1, provided in Attachment B).

Current plans for the proposed Project include the construction of a single-story building on the south side of the Project site, with parking to the north and east. The proposed Project will include 95 car parking stalls, of which 7 would be designated electric/alternative fuel spaces. The proposed Project will also include eight motorcycle parking spaces, one semi-truck and trailer parking space, and one delivery truck parking space. A bicycle rack will be provided on the northwest side of the building. The drive test lane and motorcycle skills testing area will be on the southwest corner of the Project site. The proposed Project also includes decorative fencing around the perimeter and decorative, sliding security gates at the vehicle entrances. Utility installation will include a water distribution system; gas, electric, and telephone system hookups; site lighting; and installation of a storm water collection system. Project construction is expected to take approximately 18-24 months, and is scheduled to start in the spring of 2020.

EXCAVATION PARAMETERS Over-excavation for the improved areas of the proposed Project is expected to extend to a depth of approximately 4 ft, and trenching for utilities is expected to be mainly in undocumented fill (personal communication, Department of General Services, State of California, July and August 2018). The deepest excavation associated with the proposed Project is expected to extend to a depth of approximately 30 feet (ft) for the dry wells (personal communication, Department of General Services, State of California, August 2018). However, the impact area for the dry wells is relatively small. Each of six dry wells will require an augered hole approximately 5 ft in diameter, and the total amount of material moved is expected to be approximately 130 cubic yards (personal communication, Department of General Services, State of California, August 2018).

METHODS LSA examined geologic maps of the Project site and reviewed relevant geological and paleontological literature to determine which geologic units are present in the Project site, and whether fossils have been recovered from those or similar geologic units elsewhere in the region. A search for known fossil localities was also conducted through the Natural History Museum of Los Angeles County (LACM) to determine the status and extent of previously recorded paleontological resources within and surrounding the Project site. On May 22, 2018, LSA field technician Kerrie Collison conducted a pedestrian survey by walking transects spaced less than 15 ft apart in an east-west direction across the Project site.

RESULTS

Literature Review

The proposed Project is in the southern part of the Coast Ranges Geomorphic Province of California (California Geological Survey, 2002). The Coast Ranges Geomorphic Province is characterized by mountain ranges and valleys that stretch for 600 miles from the Oregon border to the Santa Ynez River in Santa Barbara County (Norris and Webb, 1976). These mountains and valleys trend in a northwest direction, subparallel to the direction of the San Andreas Fault (California Geological Survey, 2002; Norris and Webb, 1976). The province can be divided into northern and southern subprovinces divided by San Francisco Bay (Norris and Webb, 1976).

Although geologically very similar to the northern ranges, the southern ranges lie west of the San Andreas Fault Zone and are better known because of their oil and gas resources, clearer exposures, and more intensive development (Norris and Webb, 1976). Within the province, basement rocks consist of Jurassic and Cretaceous (201.3–66 million years ago [Ma]) igneous, metamorphic, and marine sedimentary rocks that formed in island arc, subduction zone, and deep to shallow marine environments (Howard, 1979; Norris and Webb, 1976). These basement rocks are overlain by Cenozoic (less than 66 Ma) sedimentary rocks that accumulated in deep to shallow and eventually continental environments (Howard, 1979; Norris and Webb, 1976). Geologic mapping by Dibblee (1994) shows that the entire Project site contains Older Alluvium. In addition, the geotechnical report prepared for the proposed Project indicates that portions of the Project site contain undocumented fill at the surface (Geocon Consultants, Inc., 2017). These geologic units and their relative paleontological sensitivities are described in more detail below.

8/30/18 «P:\DGS1701 - Santa Maria DMV\ISMND\4.05 Cultural Resources\Paleo Memo\Santa Maria DMV Paleo Memo 083018.docx» 3

Undocumented Fill

Undocumented fill consists of sediments that have been removed from one location and transported to another location by human activity, rather than by natural means. The transportation distance can vary from a few feet to many miles, and composition is dependent on the source and purpose. While undocumented fill may contain fossils, these fossils have been removed from their original location and are thus out of stratigraphic context. Therefore, they are not considered important for scientific study. As such, undocumented fill has no paleontological sensitivity. According to the geotechnical report prepared for the proposed Project, undocumented fill was encountered from the surface to a depth of approximately 3.5 ft in the central and southern portions of the Project site (Geocon Consultants, Inc., 2017).

Older Alluvium

The Older Alluvium mapped across the Project site by Dibblee (1994) consists of wind-deposited sand, which the geotechnical report prepared for the proposed Project referred to as dune sand (Geocon Consultants, Inc., 2017). According to Geocon Consultants, Inc., (2017), the Older Alluvium is present within the Project site from the surface (or below the undocumented fill where present) to the maximum depth explored of 51 ft.

The Older Alluvium is Holocene to late Pleistocene in age (less than 126,000 years ago; International Commission on Stratigraphy [ICS], 2018; Dibblee, 1994). Although Holocene deposits can contain remains of plants and animals, only those from the middle to early Holocene (4,200 to 11,700 years ago; ICS, 2018) are considered scientifically important (SVP, 2010). These Holocene deposits overlie older Pleistocene deposits, which have produced scientifically important fossils elsewhere in the region (Jefferson, 1991a, 1991b; Miller, 1971). These older deposits span the end of the Rancholabrean North American Land Mammal Age (NALMA), which dates from 11,000 to 240,000 years ago (Sanders et al., 2009) and was named for the Rancho La Brea fossil site in central Los Angeles. The presence of Bison defines the beginning of the Rancholabrean NALMA (Bell et al., 2004), but fossils from this time also include other large and small mammals, reptiles, fish, invertebrates, and plants (Jefferson, 1991a, 1991b; Miller, 1971). There is a potential to find these types of fossils in the older sediments of this geologic unit, which may be encountered below a depth of approximately 10 ft. Therefore, these deposits are assigned low paleontological sensitivity from the surface to a depth of 10 ft and high sensitivity below that mark.

Fossil Locality Search

According to the locality search conducted by the LACM, there are no known fossil localities within the boundaries of the Project site. The LACM reports that the Project site is underlain by deposits of older Quaternary wind deposited sands overlying older Quaternary alluvial deposits derived from the Santa Maria River and associated drainages. The museum notes that these deposits typically do not contain scientifically significant fossils in the uppermost layers but they may produce important fossils at depth. The closest vertebrate locality in older Quaternary deposits similar to the deposits that may be encountered at depth within the Project site is LACM 4089. This locality is in Nipomo just west and north of the Project site, and it produced a specimen of Columbian mammoth (Mammuthus columbi).

The LACM believes that shallow excavations in the Project site are unlikely to encounter any scientifically important vertebrate fossils. However, the museum notes that deeper excavations into these deposits may encounter scientifically significant vertebrate remains and should be monitored to recover those remains. A copy of the letter describing the locality search results from the LACM is provided in Attachment C.

Field Survey

Ground visibility throughout the Project site varied from less than 25 percent in places where grasses were present to approximately 75 percent in open areas with less vegetation. Rodent burrows, modern trash, and vehicle tracks were noted throughout the Project site. Near the northern end of the Project site, concrete pads that formed the foundations of buildings demolished between 2005 and 2009 were observed. Where visible, the soil was light brown, very fine, and dry.

CONCLUSIONS AND RECOMMENDATIONS Any undocumented fill present within the Project site has no paleontological sensitivity, whereas the Older Alluvium has low paleontological sensitivity from the surface to a depth of 10 ft and high paleontological sensitivity below a depth of 10 ft. The majority of Project excavation is anticipated to be shallow, with only excavation for the dry wells extending to a depth of 30 ft. However, this deeper excavation will involve a limited impact area and is unlikely to impact paleontological resources. Therefore, LSA recommends the following mitigation measure:

PALEO-1 If paleontological resources are encountered during the course of ground disturbance, work in the immediate area of the find shall be redirected and a paleontologist shall be contacted to assess the find for scientific significance. If determined to be significant, the fossil shall be collected from the field. The paleontologist may also make recommendations regarding additional mitigation measures, such as paleontological monitoring. Scientifically significant resources shall be prepared to the point of identification, identified to the lowest taxonomic level possible, cataloged, and curated into the permanent collections of a museum repository. If scientifically significant paleontological resources are collected, a report of findings shall be prepared to document the collection.

Implementation of this mitigation measure will ensure that Project impacts to scientifically significant paleontological resources will be mitigated to a level that is less than significant.

re: Paleontological Resources Records Check for the proposed Santa Maria DMV Project, LSAProject # DGS1701, in the City of Santa Maria, Santa Barbara County, project area

Dear Sarah:

I have thoroughly searched our paleontology collection records for the locality andspecimen data for the proposed Santa Maria DMV Project, LSA Project # DGS1701, in the Cityof Santa Maria, Santa Barbara County, project area as outlined on the portion of the Santa MariaUSGS topographic quadrangle map that you sent to me via e-mail on 26 April 2018. We do nothave any vertebrate fossil localities that lie directly within the proposed project area boundaries,but we do have localities somewhat nearby from sedimentary deposits similar to those thatprobably occur at depth in the proposed project area.

The entire proposed project area has surface deposits composed of older Quaternary winddeposited sands. These deposits typically do not contain significant vertebrate fossils, at least inthe uppermost layers, and we have no localities anywhere nearby from these deposits. Atunknown depth, however, there may be older Quaternary alluvial deposits, derived from theSanta Maria River in the Santa Maria Valley and associated drainages. Our closest vertebratefossil locality in the somewhat similar older Quaternary deposits is LACM 4089, in Nipomo justwest of north of the proposed project area but not precisely located, that produced a fossilspecimen of Columbian mammoth, Mammuthus columbi.

Surface grading or shallow excavations in the older Quaternary wind deposited sands inthe proposed project area are unlikely to uncover significant vertebrate fossils. Deeperexcavations in the proposed project area that extend down into older Quaternary alluvialdeposits, however, may well encounter significant fossil vertebrate remains. Any substantialexcavations in the proposed project area, therefore, should be monitored closely to quickly andprofessionally recover any fossil remains discovered while not impeding development. Sedimentsamples should also be collected and processed to determine the small fossil potential in theproposed project area. Any fossils recovered during mitigation should be deposited in anaccredited and permanent scientific institution for the benefit of current and future generations.

This records search covers only the vertebrate paleontology records of the Natural HistoryMuseum of Los Angeles County. It is not intended to be a thorough paleontological survey ofthe proposed project area covering other institutional records, a literature survey, or any potentialon-site survey.

Sincerely,

Samuel A. McLeod, Ph.D.Vertebrate Paleontology
