REF: 8824X - SKUNK CREEK - REQUEST FOR LETTER OF MAP
REVISION - UNIVERSITY OF COLORADO AT BOULDER -
BOULDER, COLORADO

Dear Mr. Johnson:

Enclosed is the above-referenced engineering report which
provides information for the Letter of Map Revision (LOMR) of
the existing Flood Insurance Rate Map (FIRM) for Skunk Creek
in Boulder, Colorado.

This LOMR is being requested by our firm on behalf of our
client, the University of Colorado at Boulder (University), a
state entity, in order to take into account the construction
of the Skunk Creek Channel Improvement Project sponsored and
funded by the University. This improvement project
constructed a 100-year capacity channel designed to FEMA
criteria, Construction of this project was completed in the
fall of 1988. As-built topographic mapping has been prepared
of the completed project at a scale of 1-inch equals 50 feet
with a 1-foot contour interval. The mapping has a flight
date of December 5, 1988 and is prepared according to
national mapping standards. The hydraulic analysis uses this
mapping and as-built field surveyed cross sections to define
the floodplain and floodway boundaries.

The existing FIRM for Boulder was prepared utilizing the U.S.
Army Corps of Engineers HEC-2 Program.

The enclosed report defines the 100-year floodplain and
floodway for Skunk Creek by detailed methods according to the
requirements stipulated in the FEMA pUblication entitled,
"Appeals, Revisions and Amendments to Flood Insurance Maps, A
Guide for Community Officials", dated September, 1985. Our
report includes water surface profile information for the
10-, 50-, 100- and 500-year events.
