INFRASTRUCTURE & ENVIRONMENT REQUEST FOR APPROVAL 1116/13 1 RFASNA001 Santa Ana Delhi Urban Discharge Diversion Project • Records search will be conducted as a standard request. • In the event the records search results indicate the presence of known cultural resources, further cultural resources investigations may be recommended. This cost estimate does not include such additional cultural resources work. • Assumes that no paleontological search, Native American Heritage Commission Sacred Lands File search, or additional Native American Consultation is required. • The deliverable for this scope is limited to one letter request to the information center with one project map figure and one record search results summary letter report. • This cost estimate does not include any additional GIS time associated with the digitization of information resulting from the record search request or for the creation of result figures for inclusion with the letter report. Task 2.04 - Biological Field Survey and Technical Report: A biological field survey and technical report are needed to evaluate potential impacts on biological resources for the IS /MND. The survey and report are also needed as supporting documentation for resource agency permits applications (described later in Task 2.06). URS will review biological resource databases, local resource management plans, aerial photos, and any other readily available commercial data to determine the locations and types of biological resources that have the potential to occur at the Project site and general vicinity. The literature review will support the development of a brief Biological Letter Report. Following literature review, a pedestrian -based biological survey of the project site will be conducted to observe, document, and evaluate the onsite conditions and determine the potential for occurrence of common and special- status biological resources and aquatic resources. The field analysis and data collection will identify the acreages of land use and vegetation present, a list of plants and wildlife present will be compiled, and special- status species with potential to occur within the study area will be determined. The field results will be synthesized within a Biological Letter Report, which will be used in the analysis for the CEQA IS /MND as well as included as a requisite attachment to the aquatic resource permit packages. Task 2.05: - Jurisdictional Determination: For projects that may impact areas under the jurisdiction of the USACE, a jurisdictional delineation is required utilizing USACE standard delineation methods. URS evaluated the possibility of using previously - prepared Jurisdictional Delineations associated with the Santa Ana -Delhi Channel Widening project, since the channel widening areas may overlap the current project. However, based on our experience, we believe the USACE and other permitting agencies would not accept this Jurisdictional Delineation for the proposed project, and would request a project - specific delineation instead. Reasons would likely include the differing magnitude of impacts, as well as new delineation mapping standards (issued on August 6, 2012) that must be utilized in all new jurisdictional delineations. Furthermore, if utilizing previously - prepared Jurisdictional Delineation, it would be difficult to address any potential agency data requests, given that the report was prepared by another consulting firm working for a different municipality. Therefore, URS has determined it would be most appropriate to prepare a project- specific delineation for the proposed project, as discussed in the following paragraphs. URS will delineate aquatic resources within the study area utilizing the procedures and practices in the following publications and agency guidance documents: USACE Wetland Delineation Manual ; USACE Interim regional supplement to the Wetland Delineation Manual, Arid West Region, Version 2.0 ; and USACE and Environmental Protection Agency's (EPA) Clean Water Act Jurisdiction Following the U.S. Supreme Court's Decision in Rapanos v. United States & Carabell v. United States guidance document . A pedestrian -based field survey of the study area will be conducted using sub -meter GPS accuracy to precisely delineate the boundaries of potential aquatic resources. The field survey results will be synthesized into a Jurisdictional Delineation Report, which will be submitted as a requisite attachment to the USAGE, CDFG, and the RWQCB aquatic resource permit applications. The report will identify the limits of wetlands, non - wetland waters of the U.S., waters of the State, and Pagel 5 T.W1V0ITY OF SANTA ANAAUR ©AN DISCHARGE WATER DIVERSION (29880113)A2 - CONTRACTS \A.
