Dear Mr. Bender:

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 (PIS)
report for your community in accordance with Part 65 of the National Flood Insurance Program (NFIP)
regulations. In a letter dated August II, 2003, Mr. Chris Pauley, P.E., Anderson Consulting
Engineers, Inc., requested that FEMA revise the FIRM and FlS report to show the effects along Spring
Creek of updated cross-section alignments, topographic information, and floodway encroachments and of
construction of an irrigation 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 Coun\)', this area was annexed by_the_City_of.Eort.Col1ins.
This 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 of the 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.

As a result of the above-mentioned project, the Spring Creek channel was relocated. which caused the
profile stationing to change. We have revised the Spring Creek flood profile for your community to reflect
the new stations and to be consistent with the flood profile for the City of Fort Collins. No changes to the
elevations of the flood having a I-percent chance of being equaled or exceeded in any given year (base
flood) occurred in your community. The modifications are shown on the enclosed annotated copies of
Profile Panels 234P, 235P, and 236P and affected portions of the Floodway Data Table. We also have
modified the effective FIRM to update the corporate limits in the revised area. These modifications are
shown on the enclosed annotated copy of FIRM Panel 0192 C. This LOMR hereby revises the
above-referenced panel of the effective FIRM dated March 18, 1996. and the affected portions of the
FlS report dated March 23, 1999.

Because this revision request also affects the City of Fort Collins, 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.
