This letter presents a <br /> summary of the proposed revisions, a desalption of the Flood Insurance Rate Map (FIRM) <br /> revision process, and the estimated fees necessary to complete this work. <br /> As authorized at the City Council meeting on January 13, 1999, we have comoleted a <br /> preliminary floodway revision to the Clearwater Creek floodplain model. An exhibit iuustrating <br /> the potential revised floodway on Clearwater Creek west of 20 Avenue is attached for <br /> reference. The proposed floodway is shifted significantly to the north of the present `!oodway <br /> location, and is almost entirely north of the property formally known n the Lake Area Utilities <br /> Property. The proposed floodway also avoids the building on the Stevens property. The new <br /> corridor would be approximately 100 feet wide. and our modeling efforts show that t "ere will <br /> only be a minor increase In the water surface elevation upstream within the floodway. <br /> On Wednesday, May 5, 1999, we met with Mr, Paul Palzer, City of Centerville Public Works <br /> Director, and the engineers for RCWD. After discussion, Mr. Palzer recommended that we <br /> summarize the estimated casts associated with coordinating and processing a Letter of Map <br /> Revision (LOMR) with FEMA. <br /> The procedure for the LOMR submittal is described in the National Flood Insurance Program <br /> regulations and rules, last revised on May 1, 1998, in Part 85.7, Identification and Mapping of <br /> Special Hazard Areas: Roodway Revisions. The following tasks are anticipated in order to <br /> obtain approval of the change from FEMA: <br /> 0-p aa.r 808170T 170.0508. may. eoc <br /> 1328 Energy Parr; Drive .
