FDP201700008 No-Rise Analysis 2017-06-16
Draper Aden Associates Eni►ineeriirg • Sun -eying • Environmental Services Memorandum To: Chris Gensic, City of Charlottesville From: Matt James, Draper Aden Associates Date: June 16, 2017 Project Name: Meadow Creek Bridge Project Number: C09241B-11 Subject: No -Rise Analysis cc: Carolyn Howard, Draper Aden Associates The City of Charlottesville desires to construct a pedestrian bridge over Meadow Creek upstream of Greenbrier/Brandywine Drives in the City of Charlottesville and Albemarle County. The approaches for the bridge will require fill within the 1-percent-annual-chance floodplain; therefore, improvements are required to demonstrate that no -rise in the base flood elevation will occur as a result of the work to satisfy local floodplain development requirements. The proposed work is located on flood insurance rate map (FIRM) number 51003CO278D, with an effective date of March 22, 2017 as a result of LOMR case number 16-03-1697P. Please see the attached FIRM showing the location of the proposed work. The proposed bridge is adjacent to cross section number 12.95 in the effective HEC-RAS model, with the approaches parallel to channel flow as depicted in Figure 1. The results of the analysis show that there is no expected rise in floodplain or regulatory floodway elevations as a result of the project, given that the following conditions and assumptions are maintained. 1. The bridge low chord elevation is maintained above the regulatory floodway elevation (3923) at the crossing point. The current plans depict approximately 4 feet between the bridge deck and low chord elevation, which would result in a minimum bridge deck elevation of 396.3 feet. For modeling purposes, a bridge deck and maximum bridge approach elevation of 397.0 was assumed as it is slightly more conservative with respect to the grading of approaches. Please note that the floodway elevation at station 12.95 is slightly lower at 392.01; however, because the bridge is located upstream the 392.3 elevation is correct. 2. The bridge approaches will be constructed parallel to the flow and not extend past cross section 13.0 on the upstream side (south bank) and cross section 12.9 on the downstream side (north bank). 3. The bridge approaches will be constructed with a vertical wall on the channel side outside of the regulatory floodway. A vertical wall is not required on the opposing side of the approaches, and fill can be placed at approximately 2:1 slopes or flatter in these locations.
