Dear Mayor Martinez:

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 your community in accordance with Part 65 of the National Flood Insurance Program (NFIP)
regulations. In a letter dated August I 1,2003, Mr. Chris Pauley, P.E., Anderson Consulting
Engineers, Inc., requested that FEMA revise the FIRM and FIS report to show the effects along Spring
Creek of updated cross-section alignments, topographic information, and floodway encroachments and of
construction of an inigation pond from approximately 4,300 feet downstream to approximately 1,600 feet
upstream of West Horsetooth Road. Although a portion of the revised reach is shown on the effective
FIRM for the unincorporated areas of Larimer Counh', this area was_annexed_by.the_City_ofFort_Collins.
TIiis request follows up on a Conditional Letter of Map Revision issued on April 4, 2000. In response to
Mr. Pauley's request, we issued a Letter of Map Revision (LOMR) on November 24,2003 (Case
No. 03-08-0612P). However, the effective dates on the letter and annotated copies ofthe FIRM panel,
profile panels, and Floodway Data Table were stamped incorrectly. Therefore, this LOMR revises and
supersedes the November 24 LOMR.

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

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, 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 Spring Creek. As a
result of the modifications, the Base Flood Elevations (BFEs) for Spring Creek 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. The modifications are shown on the
enclosed annotated copies of FIRM Panel 001 I C; Profile Panels 28P, 29P, and 30P; and affected portions
of the Floodway Data Table. We have also modified the effective FIRM to update your community's
corporate limits in the revised area. This LOMR hereby revises the above-referenced panel of the effective
FIRM and the affected portions of the FIS report, both dated March 18, 1996.

Because this revision request also affects the unincorporated areas of Larimer County, a separate LOMR
for that community was issued on the same date as this LOMR.

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