Fairview Street Bridge Rehabilitation RFP No '1$ -001 detoured the bike path into the river bottom during summer construction on other projects in the area. Identification of construction staging, bike detours or developing alternate routes is important to gain approvals from the County. WKE has experience in working with the Harbor, Beaches and Parks Division on Memory Lane Bridge widening project, the Classell Avenue Bridge Widening projects as well as the McFadden. construction as was done on Fifth Street Rehab Maintaining the existing 12' -0" of vertical clearance over the bike paths under spans 1 and 8 is critical to the bike path operation. A wider bridge has the potential of reducing the vertical clearance. We will develop solutions to address the clearance. One alternative is to lower the bike path under the new bridge. This could be costly and difficuitto stage while maintaining bike traffic. Another option is to design a shallower bridge section to compensate for the bike path vertical curve, and deck cross slope. Matching the existing span lengths of 5T -6 ", the bridge could be designed with a depth of as little as 2' -6 ", providing the potential for an extra 1'- 6" of space over the bike path. This option could be built at less cost than the previous alternative. (a DvF�1'11 ENVIRONMENTAL CLEARANCE The City will be utilizing federal funds for the project; therefore, compliance with the National Environmental Policy Act (NEPA) will be required, in addition to compliance with the California Environmental Quality Act (CEQA). The California Department of Transportation (Caltrans) District 12 Office of Local Assistance will act as the lead agency for NEPA compliance as delegated by the Federal Highway Administration (FHWA) and the City will be the lead agency for CEQA compliance. The key environmental issues are discussed below. The first step in the environmental approval process is to complete the Preliminary Environmental Study (PES) checklist which is crucial to determining the technical studies required, as well as identifies the type of environmental documents. In our experience accurate layouts and cross sections are critical to approval of the PES by Caltrans. Our environmental experts and engineers will work closely together to develop the potential alignments to create an accurate Area of Potential Effect map prior to submittal to Caltrans. The technical reportswill be prepared forthe project based on the Caltrans Standard Environmental Reference (SER). The anticipated technical reports for the projectirclude: a Natural Environment Study Minimal Impacts (NESMI) with attached Bat Habitat Suitability Assessment and Jurisdictional Delineation Report a Section 4(f) and 6(f) Documentation: memorandums of no use or "De Minimus" findings a Historic Property Survey Report (HPSR) with attached APE map, Archeological Survey Report, records search, and Native American Consultation results a Paleontological Identification Report/ Paleontological Evaluation Report (PER /PIR) a Water Quality Assessment Report a Summary of Floodplain Encroachment Report a Noise Technical Memorandum for construction impacts 18 1 Understanding of Need Dmsign Services for Falrviow Street Bridge Rehabilitation if/7- K L 25C -24
