San Jacinto College Menifee Campus Master Plan Environmental Impact Report Project Dear Mr. Michael Milroy, We received your request on January 28, 2016, for a cultural resources records search for the Mt. San Jacinto College Menifee Campus Master Plan Environmental Impact Report Project, located in Section 2, T.6S, R.3W, SBBM, in the Menifee Valley area of Riverside County. We have reviewed our maps, records, and reports against the project area defined on the map you provided. Our records indicate that two cultural resources studies have been conducted within your project area. All of these studies involved a portion of the project area. One cultural resources property is recorded within the boundaries of the project area. Additional sources of information consulted are identified below. National Register of Historic Places (NRHP): no listed properties are located within the boundaries of the project area. California Office of Historic Preservation (OHP), Archaeological Determinations of Eligibility (ADOE): no listed sites are located within the boundaries of the project area. California Office of Historic Preservation (OHP), Historic Property Directory (HPD): no listed properties are located within the boundaries of the project area. Note: not all properties in the California Historical Resources Information System are listed in the OHP ADOE and HPD; the ADOE and HPD comprise E-1
lists of properties submitted to the OHP for review. The 1901 USGS Elsinore 30 topographic map does not indicate the presence of possible historical structures or features within the boundaries of the project area. Based on the information reviewed, one cultural resources property has been recorded within the boundaries of the project area. Examination of the updated record (33-002223) for this property indicates that as of September 2015 all physical evidence of the site had been obliterated by developments of Mt. San Jacinto College Menifee Campus. Therefore, there is only a low probability of cultural resources being present within the boundaries of the project area and further study is not recommended. However, this assessment does not rule out the possible presence of previously unidentified cultural resources. Persons involved in development of the project area should be sensitive to the significant and irreplaceable nature of cultural resources State and federal law requires that if any cultural resources are found during construction, work is to stop and the lead agency and a cultural resources professional be consulted to determine the importance of the find and its appropriate management. Sincerely, Enclosure Elizabeth Vargas Information Officer E-2

San Jacinto College Menifee Campus Project, near Menifee, Riverside County, project area Dear Michael: I have conducted a thorough search of our Vertebrate Paleontology records for the proposed Mt. San Jacinto College Menifee Campus Project, near Menifee, Riverside County, project area as outlined on the portion of the Romoland USGS topographic quadrangle map that you sent to me via e-mail on 20 January 2016. We do not have any vertebrate fossil localities that lie directly within the proposed project area, but we do have localities farther afield from sedimentary deposits similar to those that may occur subsurface in the proposed project area. The entire proposed project area has surface material composed of older Quaternary alluvial fan deposits. These deposits, so close to the source hills to the south where the bedrock is composed of metamorphic and plutonic igneous rocks, tend to be coarse and are therefore unlikely to contain significant vertebrate fossils, but there may be finer-grained material at depth that may contain significant fossil vertebrate remains. Our closest vertebrate fossil locality from somewhat similar sedimentary deposits is LACM 5168, on the north side of Railroad Canyon Reservoir just north of west of the proposed project area, that produced a specimen of fossil horse, Equus. In similar, analagous sediments, we also have locality LACM 6059, on the southeast side of Lake Elsinore further to the west-southwest of the proposed project area, that contained a specimen of fossil camel, Camelops hesternus.

Shallow excavations in the older Quaternary alluvial fan deposits exposed throughout the proposed project area are unlikely to uncover any significant vertebrate fossils. Deeper excavations that extend down into older finer-grained sedimentary deposits, however, may well encounter significant fossil vertebrate remains. Any substantial excavations in the proposed project area, therefore, should be closely monitored to quickly and professionally collect any fossils discovered without impeding development. Sediment samples should also be collected and processed to determine the small fossil potential in the proposed project area. Any fossils recovered during mitigation should be deposited in an accredited and permanent scientific institution for the benefit of current and future generations. 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.
