<br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE TOWN
<br />OF PARKER AND THE UNINCORPORATED AREAS OF DOUGLAS COUNTY, COLORADO,
<br />UNDER THE NATIONAL FLOOD INSURANCE PROGRAM
<br />
<br />The Federal Emergency Management Agency identified Special Flood Hazard Areas (SFHAs) in the Town
<br />of Parker, Colorado, on July 4, 1989, and the unincorporated areas of Douglas County, Colorado, on
<br />September 30, 1987, through issuance of a Flood Insurance Rate Map (FIRM), The Mitigation Directorate
<br />has determined that modification of the elevations of the flood having a I -percent chance of being equaled
<br />or exceeded in any given year (base flood) for certain locations in these communities is appropriate, The
<br />modified base flood elevations (BFEs) revise the FIRMs for the communities,
<br />
<br />The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (Public
<br />Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended (Title XIII
<br />of the Housing and Urban Development Act of 1968, Public Law 90-448),42 U,S,C, 4001-4128, and
<br />44 CFR Part 65,
<br />
<br />A hydraulic analysis was performed to incorporate the effects of placement of fill, construction of the Riva
<br />Ridge Street bridge, and more detailed topographic information and has resulted in a revised delineation
<br />of the regulatory floodway, an increase and decrease in SFHA width, and increased BFEs for Sulphur
<br />Gulch, The table below indicates existing and modified BFEs for selected locations along the affected
<br />lengths of the flooding source(s) cited above,
<br />

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

<br />Upon the second publication of notice of these changes in this newspaper, any person has 90 days in which
<br />he or she can request, through the Chief Executive Officer of the community, that the Mitigation
