DISCUSSION: The Storm Water Management Program was established to reduce flooding in Fort Worth, preserve streams, minimize water pollution and to operate the storm water system in a more effective manner to fully comply with state and federal regulatory requirements. This will be accomplished by infrastructure reconstruction and system maintenance, master planning, enhanced development review, and increased public education and outreach. On October 16, 2007, (Ordinance No. 17840-10-2007) City Council authorized the issuance and sale of $25,000,000.00 in Storm Water (Drainage) Revenue Bonds, Series 2007, to fund a two year Storm Water Capital project program. On December 13, 2006, the City Manager administratively executed an engineering agreement with Lockwood, Andrews and Newnam, Inc., for the study of proposed culvert improvements at 8100 Trinity Boulevard. The study has been completed and recommendations provided in order to convey local flash flood storm water flow under the roadway, assuming the Trinity River is not in flood stage. In addition, the study recommended that a Conditional Letter of Map Revision (CLOMR) be submitted and approved prior to construction and a Letter of Map Revision (LOMR) be submitted and approved after improvements are constructed to change the effective Flood Insurance Rate Map (FIRM). Amendment No. 1 for the subject engineering agreement will provide the following: . Topographic survey (approximately 2,600 linear feet) for design; . Design and preparation of engineering plans and contract documents for the bidding and construction of the recommended improvements, which include replacing the existing four 66-inch and one 60-inch pipe culverts with four 10 feet x 6 feet box culverts; .
