Santa Ana Bridge Rehabilitation and Bike Trail Structure 12/27/2004 1.3 PRELIMINARY RIGHT-OF-WAY RESEARCH AND UTILITY COORDINATION We will collect the right-of-way information from City, Caltrans and County to identify the property owners, easements, and/or airspace rights. This data will be added to the base map. For each bridge, we will define the needed right-of-way (partial or complete fee take, temporary and/or permanent easements, and airspace rights), current type of ownership, and whether relocation, relinquishments, abandonments, on -site construction, etc. will be required. We will determine who will transfer the right-of-way, the state or the local agency. This information will be summarized along with the estimated costs on Caltrans Right -of -Way Data Sheet for each structure. It is assumed that the City will complete all necessary utility coordination DELIVERABLE: ROW DATA SHEET 1.4 ROADWAY All bridge improvement plans will be based on an assumed centerline and stationing on the streets. Consultant will perform roadway design services to complete the curb and sidewalk improvements behind the bridge abutments to provide ADA conformance connections to existing sidewalks. 1.5 HYDRAULIC ANALYSIS, HYDROLOGY AND STORM DRAIN DESIGN No Hydraulic analysis of the Santa Ana -Delhi Channel will be conducted. It is assumed the existing high water elevation will be provided by OCFCD. A Storm Water Data Report will be prepared. The Project Planning Design Guide (PPDG) was revised in September 2002 to incorporate storm water quality control at the planning and design stage. The new standards require the preparation of a Storm Water Data Report (SWDR) describing the drainage, potential water quality issues, and proposed construction and permanent Best Management Practices (BMP's). This report is accompanied by checklists including all water quality items to be addressed, a cost estimate for the storm water quality efforts and construction costs, and constitutes "Appendix E" of the PPDG. This report will describe the drainage and water quality conditions of the project area, evaluate potential issues and propose best management practices (BMP's) to mitigate existing and future conditions, as well as construction related water quality prevention requirements. Also part of the NPDES requirements, the NPDES Information Submittal form will be prepared. DELIVERABLE: STORM WATER DATA REPORT 1.6 RAILROAD COORDINATION The Flower Street Bike Trail Structure may encroach on UPRR ROW as well as require the modification of the existing Railroad Crossing Guard Gates. WKA assumes the City will obtain all the necessary permits and access permissions from the UPRR and PUC as part of the bikeway design, as well as the design for all required RR crossing gates. The WKA team will provide the necessary information to the City for UPRR coordination. For each of the four structures, the existing drainage conditions will be reviewed
