~ 1 2 As a result of updated topographic information, the split flow shown on the effective FIRM has been eliminated. As a result of the channel improvements, the base (lOO-year) flood elevations (BFEs) decrease by a maximum of 11 feet. The Special Flood Hazard Area increases and decreases, but all increases are contained in the channel. The floodway also increases and decreases throughout this revised reach. All affected property owners have been notified by mail of the revision. The modifications are shown on the enclosed annotated copy of FIRM Panel 0154 C, Profile Panels 15P and l6P, and the Floodway Data Table for Cottonwood Creek. This LOMR hereby revises this panel of the effective FIRM dated March 2, 1989, and the Flood Profiles and Floodway Data Table in the FIS report dated September 30, 1992. Due to the channel improvements, the stream length has been shortened. To account for the difference, an equality is shown on Profile Panel 16P and the Floodway Data Table at Cross Section W. The following table is a partial listing of existing and modified BFEs: Existing BFE Modified BFE Location (feet>* (feet)* Approximately 2,180 feet downstream of Union Boulevard 6,460 6,449 Approximately 2,000 feet downstream of Union Boulevard 6,461 6,459 Approximately 1,000 feet downstream of Union Boulevard 6,481 6,473 Approximately 800 feet downstream of Union Boulevard 6,483 6,483 *Referenced to the National Geodetic Vertical Datum, rounded to the nearest whole foot Public notification of the proposed modified BFEs will be given in the Gazette TeleRraDh on or about August 4 and August 11, 1994. A copy of this notification is enclosed. In addition, a notice of changes will be published in the Federal ReRister. We encourage you to supplement this notification by preparing an article for publication in your community newspaper. This article should describe the changes that have been made and the assistance your community will give in providing data and interpreting the NFIP maps. Because this LOMR will not be printed and distributed to users such as insurance agents and lenders, your community will serve as a repository for the new data. The revisions are effective as of the date of this letter; however, within 90 days of the second publication in the Gazette TeleRraDh, a citizen' may request that the Federal Emergency Management Agency (FEMA) reconsider the determination made by this LOMR. Any request for reconsideration must be based on scientific or technical data. All interested parties are on notice that, until the 90-day period elapses, the determination to modify the BFEs presented in this LOMR may itself be modified.
