Preliminary Environment 17. Is there a potential for wetlands to occur within or adjacent to the construction area? Based on a preliminary review of the project site no surface waters are present. Per the National Wetland Inventory (NWI) maps, available through the Natural Resource Conservation Service (NRCS) field office, and the Wetlands Online Mapper (U.S. Fish and Wildlife Service, Wetlands Online Mapper, http: //www.fws.gov/wetlands /Data /Mapper.html), which is based on the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory database, there are no wetlands on, immediately adjacent to, or in the vicinity of the proposed project. The potential for wetlands to occur within or adjacent to the project, and the potential for the project to affect wetlands, if any, will be confirmed during the detailed field evaluation performed as part of the NES (MI). Based on a preliminary review of the project site wetlands are not anticipated to be encountered within or adjacent to the identified limits of disturbance. 18. Is there a potential for agricultural wetlands to occur within or adjacent to the construction area? According to the Wetlands Online Mapper (U.S. Fish and Wildlife Service, Wetlands Online Mapper, http: / /www.fws.gov /wetlands /Data /Mapper.html), which is based on the U.S. Fish and Wildlife Service National Wetlands Inventory database, there are no wetlands on, immediately adjacent to, or in the vicinity of the proposed project. The potential for agricultural wetlands to occur within or adjacent to the project, and the potential for the project to affect agricultural wetlands, if any, will be confirmed during the field evaluation performed as part of the NES (MI). Based on a preliminary review of the project site wetlands, including agricultural wetlands, are not anticipated to be encountered within or adjacent to the identified limits of disturbance. 19. Is there a potential for the introduction or spread of invasive plant species? During construction there would be the potential for the spread of invasive species through introduction from construction equipment and other outside sources. Standard Department construction best management practices (BMPs) would be implemented during construction to limit the potential for the introduction or spread of invasive species. This will be addressed in the NES (MI) that is prepared. Sections 4(f) and 6(f) 20. Are there any historic sites or publicly owned public parks, recreation areas, wildlife or waterfowl refuges (Section 4[f]) within or immediately adjacent to the construction area? It is not anticipated that any Section 4(f) resources would be impacted by the proposed project as no publicly owned parks or recreation areas, wildlife or waterfowl refuges, or known historic sites are located within or immediately adjacent to the proposed project site. One site, the Orange County Highway Department (now Road Department) industrial /maintenance yard located at 1102 East Fruit Street (buildings number 3 through 9) was previously identified as being eligible for listing on the National Register of Historic Places. However, this finding does not appear to be appropriate for this site and will be addressed in the Historic Property Survey Report/Historical Resources Evaluation Report that is prepared for the project. Is anticipated that this site will be determined to not be eligible for listing on the NRHP and therefore would not be a Section 4(f) resource. 21. Does the project have the potential to affect properties acquired or improved with Land and Water Conservation Fund Act (Section 6[f]) funds? No parks are located within or adjacent to the proposed project site. No properties acquired with Land and Water Conservation Fund (Section 6(f)) funds would be impacted by the proposed project. Visual Resources 22. Does the project have the potential to affect any visual or scenic resources? The project vicinity consists of primarily light industrial and warehouse uses to the east of Lincoln Avenue. In the northwest quadrant of the Santa Ana Boulevard /OCTA Metrolink at -grade crossing are predominantly single - family uses, while the southwest quadrant is the Santa Ana Regional Transportation Center. To the west of Santiago Street to the north and south of Santa Ana Boulevard multi - family residential units are present. The Visual Impact Assessment Guide was completed for the proposed project. Based on a preliminary review of the project site and the information known about the project area the proposed project received a scope of 17. Based on these results an abbreviated Visual Impact 5 19E -76
