• 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 or 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. • The 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. 3.3 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 5). 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 Technical Report. Following the literature review, URS will conduct a pedestrian -based biological survey of the project site (channel diversion area, retention basin area, and pipeline route) 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 resource agencies' permit packages. 34 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 with the current project. However, based on our experience, we believe the USACE and other perm tting 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 USACE jurisdictional delineations. Furthermore, if utilizing a 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 wonting 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. The study area includes aquatic resource areas that will be impacted by the project, which likely will be limited to the diversion area of the Santa Ana Dellni Channel. For the delineation, URS will utilize procedures and practices in the 25F2'50
