Dear Mayor Moss:

This responds to a request that the Federal Emergency Management Agency (FEMA) comment on the
effects that a proposed project would have on the effective Flood Insurance Rate Map (FIRM) for your
community, in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a
letter dated December 3, 2001, Mr. Dan Blankenship, P.E., City of Westminster, requested that FEMA
evaluate the effects that proposed channelization and relocation of Quail Creek would have on the flood
hazard information shown on the effective FIRM.

The proposed project consists of the channelization and relocation of Quail Creek between Huron Street
and Big Dry Creek and the relocation of the Bull Canal. The Quail Creek channel will contain the flood
having a I-percent chance of being equaled or exceeded in any given year (base flood).

All data required to complete our review of this request for a Conditional Letter of Map Revision
(CLOMR) were submitted with letters from Mr. Frank Casteleneto, P.E., City of Thornton, Mr. Burt
Knight, P.E., City and County of Broomfield, Mr. Edward L. Lind, P.E., Felsburg Holt & UlIevig, and Mr.
Blankenship.

We reviewed the submitted data and the data used to prepare the effective FIRM for your community and
determined that the proposed project meets the minimum floodplain management criteria of the NFIP. We
believe that, ifthe proposed project is constructed as shown on the drawings entitled "Quail CreeklBull
Canal Relocation," prepared by Felsburg Holt & UlIevig, dated September II, 2001, and the data listed
below are received, the floodplain boundaries of the base flood will be delineated as shown on the drawing
entitled "Proposed Floodplains," prepared by Felsburg Holt & UlIevig, dated February 28, 2002.

The Special Flood Hazard Area (SFHA), the area that would be inundated by the base flood, will increase
and decrease, as a result of the proposed project. The increases in SFHA are result of the relocation of
Quail Creek through an area previously not identified as SFHA. The maximum decrease in the width of
the SFHA, approximately 1,300 feet, will occur approximately 400 feet east of Huron Street.

Upon completion of the project, your community may submit the data listed below and request that we
make a final determination on revising the effective FIRM.

. Detailed application and certification forms, which were used in processing this request, must be
used for requesting final revisions to the maps. Therefore, when the map revision request for the
