CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE TOWN OF PARKER AND THE UNINCORPORATED AREAS OF DOUGLAS COUNTY, COLORADO, UNDER THE NATIONAL FLOOD INSURANCE PROGRAM On February 2, 1996, and January 5, 1996, respectively, the Federal Emergency Management Agency identified Special Flood Hazard Areas (SFHAs) in the Town of Parker and in the unincorporated areas of Douglas County, Colorado, through issuance of Flood Insurance Rate Maps (FIRMs). The Mitigation Directorate has determined that modification ofthe elevations of the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) for certain locations in these communities is appropriate. The modified Base Flood Elevations (BFEs) revise the FIRMs for the communities. 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. A hydraulic analysis was performed to incorporate the effects of channelization along Newlin Gulch from the confluence with Cherry Creek to approximately 1,800 feet upstream; construction of a pedestrian bridge across Newlin Gulch approximately 175 feet upstream ofthe confluence with Cherry Creek; and placement offill within the floodway fringe of Cherry Creek from the confluence of Newlin Gulch to approximately 2,000 feet downstream. This has resulted in a revised delineation of the regulatory floodway, increases and decreases in SFHA width, and increased and decreased BFEs for Newlin Gulch. The aforementioned channelized portion of Newlin Gulch contains the base flood. This has also resulted in increases and decreases in SFHA width and increased BFEs for Cherry Creek. Because the increases in BFE along Cherry Creek are less than 0.5 foot and do not change the whole-foot BFEs shown on the effective FIRMs, they will not be published. The table below indicates existing and modified BFEs for selected locations along the affected lengths ofthe flooding source(s) cited above. Location Existing BFE (feet)* Modified BFE (feet) * Newlin Gulch: Approximately 500 feet upstream of confluence with Cherry Creek Approximately 2,040 feet upstream of confluence with Cherry Creek 5,778 5,776 5,798 5,799 *National Geodetic Vertical Datum, rounded to nearest whole foot Under the above-mentioned Acts of 1968 and 1973, the Mitigation Directorate 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 Mitigation Directorate 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 Mitigation Directorate's determination to modify the BFEs may itself be changed.
