Dear Mayor Burkholder:

This responds to a request that the Department of Homeland Security's Federal Emergency Management
Agency (FEMA) revise the effective Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS)
report for Jefferson County, Colorado and Incorporated Areas (the effective FIRM and FIS report for your
conununity), in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations.
With a transmittal dated August II, 2003, Mr. Hany F. Strasser, P.E., Project Manager, David Evans and
Associates, Inc., requested that FEMA revise the FIRM and FIS report to show the effects of channel
modifications along Weaver Creek, associaled with development of The Preserve at Weaver Creek, from
approximately-1,340.feet.downstream.to'just'upstream'orWesrHampden-Avehue. Die cliannel
modifications included construction of a stormwater detention facility, placement of fill, and encroachment
into the floodplain along lhe wesl side of Weaver Creek through the revised reach. This request follows up
on a Condilional Letter of Map Revision issued on November 9, 200 I.

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

With a Letter of Map Revision (LOMR) dated May 30,2003, that became effective on September 25,
2003 (Case No. 03-08-0167P), FEMA revised the FIRM and FIS report to show the effects of channel
modifications along Weaver Creek from approximately 1,340 feet downstream to just upstream of West
Hampden Avenue. The channel modifications included a low-water pedestrian trail crossing, two
stormwater detention facilities, placement of fill, and encroachment into the floodplain along the east side
of Weaver Creek through the revised reach. This LOMR also is being issued to show on the FIRM
additional flood hazard information along Weaver Creek thai was omitted from the September 25 LOMR
and 10 update the flood profiles issued with lhat LOMR.

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 boundary delineations of the flood having a I-percent chance of being equaled or exceeded in
any given year (base flood) along the revised reach of Weaver Creek. As a result of the modifications, the
Base Flood Elevations (BFEs) and lhe width of the Special Flood Hazard Area (SFHA), the area that
would be inundated by the base flood, for Weaver Creek increased in some areas and decreased in other
areas. The modifications are shown on the enclosed annotated copies of FIRM Panel 08059C03l5 E and
Profile Panels 560P and 561P. 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.
