Abrahams, Seismic Performance of Movable Bridges WPI Segment No.: 430051-1 Location Hydraulics Technical Memorandum The study limits of the SR 50 Corridor traverses 15 project basins within the Bystre Lake, Croom, and Eastern Hernando Withlacoochee River Watershed. There are 18 cross drains and 1 bridge culvert (Bridge No. 080036) within the study limits. The proposed bridge low member is currently planned to be the same. The mean high water elevation (high tide) is 1.33'. This gives a clearance under the bridge when the tide is high of about 4.9'. The Florida Department of Transportation (FDOT) Bridge Hydraulics Handbook gives the following guidance: 2.4.2 Navigation The Bridge Hydraulics Recommendations Sheet (BHRS) provides a single reference that summarizes the findings and recommendations of the hydraulic analyses. Details in the FDOT Design Manual (Chapter 305.2) provide a guide to populate the BHRS. FDOT's Median Handbook and related guidance to address: existing median access (if applicable F. Bridge Hydraulic Report (BHR) and Recommendation Sheet (BHRS) 1. The CONSULTANT shall provide a BHR and BHRS for bridge structures, including a scour analysis in accordance with the FDOT Drainage Manual and Handbooks. Signed, dated, and sealed copies of the BHR and BHRS shall be submitted to the DEPARTMENT. The Location Hydraulics Memorandum LHM) (March 2015)( was prepared as a component of the PD&E Study. The purpose of the LHM is to assess highway encroachment impacts within the 100- year (base) floodplains and any regulatory floodways that are associated with the proposed action. grades on the bridge, and horizontal alignment will not change). Regardless of the four options proposed for the project, no scenario is expected to negatively influence channel hydraulics. 4.2. Environmental Resource Permitting Analysis The two permit numbers cited by the SFWMD during the ETDM process were 36-02058-S and 36-
