"'~ . " Federal Emergency Management Agency Washington, D.C. 20472 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No.: 03-08-0545P The Honorable Ed Moss Mayor, City of Westminster 4800 West 92nd Avenue Westminster, CO 80031 Community: City of Westminster, CO Community No.: 080008 Panel Affected: 08059C0093 E Effective.Date of SEP 05 2003 This RevlSlon: 102-REISSUE Dear Mayor Moss: This Letter of Map Revision (LOMR) was prepared by the Federal Emergency Management Agency (FEMA) to reissue a LOMR dated March 12, 2003, which became effective on July 10, 2003 (Case No. 03-08-0145P), in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. The March 12 LOMR, requested by Mr. David W. Loseman. P.E., L.S., Floodplain Manager, Department of Community Development, City of Westminster, revised the effective Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FrS) for your community to show the effects of the'conveyance'of-North,Gity,Park,Greek-in,a,storm,sewer,system,through,the.Legacy~idge West development and construction of two detention ponds. On June 17, 2003, FEMA issued a new FIRM and FrS report for Jefferson County, Colorado, and its incorporated areas in our countywide format. Because this effective date was already established for the new FIRM and FrS report, the modifications made by the March 12 LOMR were not incorporated into these maps and were subsequently superseded. This LOMR reissuance incorporates the modifications made by the March 12 LOMR and revises the newly effective FIRM and FrS report. As part of the Legacy Ridge West development, the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) is conveyed in the storm sewer system through the site from North Sheridan Boulevard to approximately 1,450 feet upstream, at the limit of detailed study. The two detention ponds, Filing-7 Pond I (Pond I) and Filing-7 Pond 2 (Pond 2), are located approximately 800 feet upstream and approximately 200 feet upstream of North Sheridan Boulevard, respectively. The Special Flood Hazard Areas (SFHAs), the areas that would be inundated by the base flood, for Ponds I and 2 are designated Zone AE, SFHAs with Base Flood Elevations (BFEs) determined, The SFHA and the regulatory floodway along the remainder of the revised reach are contained within the storm sewer system. We have revised the FIRM and FrS report to incorporate the modifications made by the March 12 LOMR along North City Park Creek. As a result, the BFEs and the width of the SFHA for North City Park Creek increased in some areas and decreased in other areas, and the width of the regulatory floodway decreased, The modifications are shown on the enclosed annotated copies of FIRM Panel 08059C0093 E, Profile Panel 346P, the Summary of Stillwater Elevations Table, and affected portions of the Floodway Data Table. This LOMR hereby revises the above-referenced panel of the effective FIRM and the affected portions of the FIS report, both dated June 17,2003.
