CHANGES ARE MADE IN DETERMINA nONS OF BASE FLOOD ELEV A nONS FOR ADAMS
COUNTY, COLORADO, UNDER THE NA nONAL FLOOD INSURANCE PROGRAM

On August 16, 1995, the Federal Emergency Management Agency identified Special Flood Hazard Areas
(SFHAs) in the Adams County, Colorado, through issuance of a Flood Insurance Rate Map (FIRM). The
Federal Insurance and Mitigation Administration has determined that modification of the elevations of the
flood having a I-percent chance of being equaled or exceeded in any given year (base flood) for certain
locations in this community is appropriate. The modified Base Flood Elevations (BFEs) revise the FIRM
for the community.

The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (public
Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended
(Title XIII of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C.
4001-4128, and 44 CFR Part 65.

Hydrologic and hydraulic analyses were performed to reflect existing channel conditions along Quail
Creek from approximately 1,600 feet downstream of Sheridan Parkway to Country Estates Pond, which is
located just upstream of South 124th Street, and along Tributary D from the confluence with Quail Creek
to approximately 50 feet downstream of South 124th Street. This has resulted in an increase and decrease
in SFHA width along Quail Creek and Tributary D. In addition, BFEs were established for Quail Creek
from approximately 1,600 feet downstream to approximately 100 feet downstream of Sheridan Parkway.
The table below indicates existing and modified BFEs for selected locations along the affected lengths of
the flooding source(s) cited above.

Under the above-mentioned Acts of 1968 and 1973, the Federal Insurance and Mitigation Administration
must develop criteria for floodplain management. To participate in the National Flood Insurance Program
(NFIP), the community must use the modified BFEs to administer the floodplain management measures
of the NFIP. These modified BFEs will also be used to calculate the appropriate flood insurance premium
rates for new buildings and their contents and for the second layer of insurance on existing buildings and
contents.

Upon the second publication of notice of these changes in this newspaper, any person has 90 days in
which he or she can request, through the Chief Executive Officer of the community, that the Federal
Insurance and Mitigation Administration reconsider the determination. Any request for reconsideration
must be based on knowledge of changed conditions or new scientific or technical data. All interested
parties are on notice that until the 90-day period elapses, the Federal Insurance and Mitigation
Administration's determination to modifY the BFEs may itself be changed.
