ThIs ReVISIOn:

Dear Mr. Sullivan:

This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective
Flood htsurance Rate Map (FIRM) and Flood htsurance Study (FIS) report for your community in
accordance with Part 65 of the National Flood htsurance Program (NFIP) regulations. ht a letter dated
November 21,2002, Mr. Thomas C. Fairley, P.E., Principal, Kiowa Engineering Corporation, requested
that FEMA revise the FIRM and FIS report to show the effects of channel modifications associated with
the Pinery Wesl development along Cherry Creek from approximately 3,880 feet downstream to
approximately 4,280 feet upstream ofthe confluence with Bayou Gulch and along Bayou Gulch from the
confluence with Cherry Creek to approximately 600 feet upstream of State Highway 83 (SH83). The
channel modifications include the Bayou Gulch Road Bridge (formerly called the Jordan Road Bridge)
project; placement of fill along Cherry Creek from the confluence with Bayou Gulch to approximately
5,500 feet north of the confluence; and placement offill along the north bank of Bayou Gulch from the
confluence with Cherry Creek east to Parker Road. The placement of fill is within portions of the
regulatory floodways for both Cherry Creek and Bayou Gulch. This request follows up on a Conditional
Letter of Map Revision issued on December 3, 1999.

All data required 10 complete our review of this request were submitted with letters from Mr. Fairley.

We have completed our review of the submitted data and the flood data shown on the effective FIRM and
in the effective FIS report. We have revised the FIRM and FIS report to modify the elevations and
floodplain and floodway boundary delinealions of the flood having a I -percent chance of being equaled or
exceeded in any given year (base flood) along Cherry Creek and Bayou Gulch through the revised
reaches. As a result of the modifications along Cherry Creek, the Base Flood Elevations (BFEs) and the
widths of the Special Flood Hazard Area (SFHA), the area that would be inundated by the base flood, and
the regulatory floodway increased in some areas and decreased in other areas. As a result of the
modifications along Bayou Gulch, the BFEs decreased, and the widths of the SFHA and the regulatory
floodway increased in some areas and decreased in other areas. The modifications are shown on the
enclosed annotated copies of FIRM Panels 0185 D and 0195 C; Profile Panels 64P, 65P, and lOOP; and
affected portions of the Floodway Data Table. This Letter of Map Revision (LOMR) hereby revises
