The reV1S10ns are effective as of the date of this letter; however, a review
of the determination made by this LOMR and any requests to alter this
determination should be made within 30 days. Any request to alter the
determination must be based on scientific or technical data.

Due to present funding constraints, the Federal Emergency Management Agency
(FEMA) must limit the number of physical map reV1S10ns processed.
Consequently, we will not republish the FIRM for the Town of Hayden to
reflect the determination of this LOMR at this time. However, when changes
to FIRM Panel 0001 B f"r your community warrant a physical revision and
republication in the future, the determination in this LOMR will be
incorporated at that time.

Because this revision does not involve any floodway changes, we are not
enclosing an annotated Flood Boundary and Floodway Map (FBFM). Unless a
subsequent physical map revision involves floodway changes for FBFM Panel
0001, we will not revise it to show the changes made by this LOMR.

J;'lease note that the flows from the "Hayden Floodway" downstream of the
Denver and Rio Grande Western Railroad present an increased flood risk to
property in Routt County where the effective FIRM shows the entire area to be
Zone X (areas determined to be outside the 500-year floodplain). Revisions
to show the flood hazard areas in the county will not be made at this time,
but wil1 be incorporated when changes to the FIRM for Routt County warrant a
physical map revision. .

The basis of this LOMR is a channel-modification project. NFIP regulations,
as cited in Paragraph 60.3{b){7), require that communities assure that the
flood-carrying capacity within the altered or relocated portion of any
watercourse is maintained. This provision is incorporated into your
community's existing floodplain management regulations. Consequently, the
ultimate responsibility for maintenance of the channel modification rests
with your community.

Because this LOMR will not be printed and distributed to primary users, such
as local insurance agents and mortgage lenders, your community will serve as
a repository for the new data. We encourage you to disseminate the
information reflected by this LOMR widely throughout the community, so that
interested persons, such as property owners, insurance agents, and mortgage
lenders, may benefit from the information. We also encourage you to give
consideration to preparing an article for publication in your community's
local newspaper. This article should describe the changes that have been
made and the assistance your community will give in providing the data and
interpreting the NFIP maps.

The map as listed above and as revised by this letter will be used for all
flood insurance policies and renewals issued for your community.

This determination has been made pursuant to Section 206 of the Flood
Disaster Protection Act of 1973 (P.L. 93-234) and is in accordance with the
National Flood Insurance Act of 1968, as amended (Title XIII of the Housing
and Urban Development Act of 1968, P.L. 90-448), 42 U.S.C. 4001-4128, and 44
CFR Part 65. Pursuant to Section 1361 of the National Flood Insurance Act of
1968, as amended, communities participating in the NFIP are required to adopt
