Santa Ana Bridge Rehabilitation and Bike Trail Structure 12/27/2004 girder and replacing the sidewalk girder with cast -in -place concrete. The second alternative will investigate using precast girders. This may be advantageous in that it may reduce the impact on the channel during construction Bridge Type Selection Report will be prepared that contains the material as required under I&P Guide 4-2. We will also prepare General Plan Estimates for all the structure alternatives that have been studied during the Type Selection process, and will confirm the proposed foundation design for the bike path following foundation recommendations contained in the Final Foundation Report. DELIVERABLES: BRIDGE GENERAL PLANS (4) BRIDGE TYPE SELECTION REPORT (4) GP ESTIMATES (4) 1.9.1 HBRR COMPLIANCE The Bridge Type Selection designs will be designed to meet the HBRR requirements that will remove the three bridges from the EBL and strive to follow the HBRR approved scope. The City will be notified if any HBRR scope change is required to be processed due to new design considerations. WKA will process through Caltrans the change in scope forms 6A and 6D of the Local Assistance Program Guidelines as well as coordinate with Caltrans District Local Assistance on their approval. DELIVERABLES: HBRR SCOPE CHANGE APPLICATION (IF REQUIRED) TASK 2.O - ENVIRONMENTAL APPROVAL It is assumed that the City has obtained approval of the CEQA and NEPA documents for the Flower Street Bridge Rehabilitation. To begin the environmental process for the other three structures, a Preliminary Environmental Study is required for each project. A signed PES is assumed to be completed by the City prior to the start of this project. TASK 2.1 : INITIAL SITE ASSESSMENT Fifth Street and McFadden Avenue Bridges both are part of a recent seismic retrofit project and thus are assumed to have a current ISA checklist. For Flower Street Bike Trail Structure, pursuant to Caltrans requirements, RBF will prepare an Initial Site Assessment (ISA) consisting of a regulatory database search, site walkover and completion of the standard Caltrans ISA Checklist. TASK 2.2: MINIMAL NATURAL ENVIRONMENT STUDY A literature review will be conducted to determine which species have been identified as special status by state, federal, and local resources agencies and organizations, and have a potential to occur within the project site or immediate vicinity. Sources to be reviewed include: (1) special status species lists from the California Department of Fish and Game (CDFG), U.S. Fish and Wildlife Service (USFWS), and California Native Plant Society (CNPS); (2) database searches of the California Natural Diversity Database (CNDDB) and the Electronic Inventory of the CNPS; (3) the most recent Federal Register listing package and critical habitat determination for each federally -listed Endangered or Threatened species potentially occurring within the project site; (4) the
