Santa Ana Bridge Rehabilitation and Bike Trail Structure 12/27/2004 CDFG Annual Report on the status of California's listed Threatened and Endangered plants and animals; and (5) other biological studies conducted in the vicinity of the project site. Vegetation types will be mapped to identify and describe the extent and distribution of various vegetation types on the project site, including any special status vegetation types. A description of the existing quality and species composition of the vegetation types on the project site will be compiled based upon observations and field notes taken during the survey and will be included with the documentation for the project site. A general walk -over survey will be conducted to document existing wildlife use on the project site, including an assessment of the potential for special status plant and wildlife species that may be present. This survey will be conducted simultaneously with vegetation mapping. Three (3) Minimal Impact Natural Environment Studies, consistent with the current guidelines, will be developed based on the results of various biological surveys, analysis, and data compilation described above. Each report will describe: (1) the methodology used to conduct the biological surveys; (2) a detailed description of the existing vegetation types and associated wildlife resources on the project site; (3) potential impacts from project development; and (4) recommended mitigation measures to reduce identified impacts to less than significant levels. TASK 2.3A: SECTION 106 COMPLIANCE (HBRR BRIDGES) Consultant will secure a cultural resources records search from the South Central Coastal Information Center (SCCIC) at California State University, Fullerton. The records search will provide data on known cultural resources and on previous studies within one mile of each project. Data sources consulted at the SCCIC will include archaeological and structural resource records, historic maps, and the Historic Resource Inventory (HRI) maintained by the California Office of Historic Preservation (OHP) for Orange County, listing all National Register of Historic Places (NRHP), California Register of Historic Resources (CRHR), State Historical Landmarks (SHL), and California Points of Historical Interest (PHI). Consultant will review the Orange County Historical Commission's (OCHC) Inventory of Historical Sites. Consultant will conduct a short site visit at each project location. The location will briefly be examined for prehistoric (Native American) and historic (non -Native American) archaeological evidence as well as historic built -environment resources (e.g., bridges and other structures). Consultant will prepare a letter report for each of the two bridge rehabilitation locations summarizing the results of the records search and site visit for each location. The reports will describe the potential of the project to adversely affect any potentially significant cultural resources. Consultant assumes that these three projects will be classified by Caltrans as screened undertakings under the recent Programmatic Agreement (PA). TASK 2.3B: SECTION 106 COMPLIANCE BIKE TRAIL) In addition to the works described in the previous section for Section 106 Compliance for HE RR Fifth, McFadden and Flower Street, consultant will prepare Caltrans-specific Section 106 documents appropriate under the PA for the proposed Flower Street
