Dear Mayor Tanner:

This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective Flood
Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report for Arapahoe County, Colorado and
Incorporated Areas (the effective FIRM and FIS report for your community), in accordance with Part 65 of the
National Flood Insurance Program (NFIP) regulations. In a letter dated September 17, 1997, Mr. David J.
Love, P.E., Love & Associates, Inc., requested that FEMA revise the FIRM and FIS report to show the effects
of construction of two 12-foot by 25,foot pre'cast, three-sided box culverts at Fairway Lane and channel
modifications along Dutch Creek from approximately 110 feet upstream of Fairway Lane to the confluence with
the South Platte River. The revised reach extends from approximately 1,250 feet upstream of Fairway Lane
to the confluence with the South Platte River. This request follows up on a Conditional Letter of Map Revision
issued on December 1, 1995.

All data required to complete our review of this request were submitted with letters from Roger L.
Peterson, Ph.D., P.E., Love & Associates, Inc., and Mr. Love.

We have completed our review of the submitted data and the flood data shown on the effective FIRM and
FIS report. We have revised the FIRM and FIS report to modify the elevations, floodplain and floodway
boundary delineations, and zone designations of the flood having a I-percent chance of being equaled or
exceeded in any given year (base flood) along the revised reach of Dutch Creek. As a result of the
modifications, the base flood elevations (BFEs) for the revised reach increased in some areas and decreased in
other areas; the width of the Special Flood Hazard Area (SFHA), the area that would be inundated by the base
flood, increased in some areas and decreased in other areas; and the width of the regulatory floodway increased
in some areas and decreased in other areas. The modifications are shown on the enclosed annotated copies of
FIRM Panel 08005C0435 J, Profile Panel 54P, and affected portions of the Floodway Data Table. This Letter
of Map Revision (LOMR) hereby revises the above-referenced panel(s) of the effective FIRM and the affected
portions of the FIS report, both dated August 16, 1995.

Because this revision request also affects the City of Littleton and Arapahoe County, separate LOMRs for those
communities were issued on the same date as this LOMR.

The modifications are effective as of the date shown above. The map panel(s) as listed above and as modified
by this letter will be used for all flood insurance policies and renewals issued for your community.
