Dear Mayor Isaac:

This is in response to a request for a revision to the effective Flood
Insurance Study (FIS) and National Flood Insurance Program (NFIP) map for
your community. Specifically, this responds to a letter dated July 8,'1994,
from Mr. Dan Bunting, Regional Floodplain Administrator, Regional Building
Department, regarding the effective FIS report and Flood Insurance Rate Map
(FIRM) for the City of Colorado Springs, Colorado. Mr. Bunting requested
that we revise the effective FIRM to show the effects of updated( topographic
information, a channelization project from the Colorado and Eastern Railroad
to North Carefree Circle, and existing culverts at Constitution Avenue anCi
North Carefree Circle that were not previously modeled along Sand Creek.

All data required to complete our review of this request were submitted with
Mr. Bunting's letters dated May 24 and July 8, 1994. Because this Letter of
Map Revision (LOMa) shows the effects of a publicly sponsored flood-control
project that reduces flooding to existing development, fees were not assessed
for the review.

"

We have completed our review of the submitted data and the flood ,data shown
on the effective FIRM, and have revised the FIRM to modify the elevations an~
floodplain and floodway boundary delineations of a flood having a l-percent
probability of being equaled or exceeded in any given year (base flood) along
Sand Creek from the Colorado and Eastern Railroad to approximately'3,000 feet
upstream of North Carefree Circle. This revision is based on hydraulic
analyses performed to evaluate the impact of the channelization of Sand Creek
from the Colorado and Eastern Railroad to North Carefree Circle and the
effects of culverts at Constitution Avenue and North Carefree Circle. In
addition, the analyses reflect updated topographic information. As a result
of the revision, the Special Flood Hazard Area and floodway have been
relocated and the base (lOO-year) flood elevations (BFEs) have increased
along the entire revised reach.
