FIRM-010223Federal Emergency Management Agency Washington, D.C. 20472 o o CERTIFIED MAIL IN REPLY REFER TO: RETURN RECEIPT REQUESTED February 23, 2001 The Honorable Candy Sheehan Mayor, City of Coppell 255 Parkway Boulevard Coppell, TX 75019 Dear Mayor Sheehan: 19P -A Community: City of Coppell, TX Community No.: 480170 Map Panels Affected: 48113C0135 J, 0145 J, 0155 J, and 0160J This is to formally notify you of the final flood elevation determination for the City of Coppell, Dallas County, Texas, in compliance with Title 44, Chapter I, Part 67, Section 67.11, Code of Federal Regulations (CFR). This section requires that notice of final flood elevations shall be sent to the Chief Executive Officer of the community, all individual appellants, and the State Coordinating Agency, and shall be published in the Federal Register. On September 7, 2000, the Federal Emergency Management Agency (FEMA) provided your community with revised Preliminary copies of the Flood Insurance Study (FIS) report and Flood Insurance Rate Map (FIRM) for Dallas County, Texas and Incorporated Areas for your review and comment. FEMA prepared the updated FIRM directly from the effective FIRMS for your community and other communities in Dallas County using a process that involves capturing data in a digital (computer- readable) format and plotting map panels using a specialized computer technology. The effective FIRMS identified the Special Flood Hazard Areas (SFHAs), areas that would be inundated by the flood having a 1- percent chance of being equaled or exceeded in any given year (base flood), in your community and other communities in Dallas County. We have incorporated all essential information from the previously effective FIRMS, including Base Flood Elevations (BFEs). As part of this FIRM update we have also incorporated additional new detailed flood hazard data prepared by the U.S. Army Corps of Engineers, Fort Worth District. This data includes revised analyses for Trinity River, Elm Fork Trinity River, West Fork Trinity River, and Ten Mile Creek. This data also affects the lower reaches of tributaries to these flood sources. During the processing of the updated FIS report and FIRM, we determined that modifications to the proposed BFEs for Dallas County, Texas and Incorporated Areas were appropriate. The proposed BFEs for your community were published in the Citizen's Advocate on January 28 and February 4, 2000, and in the Federal Register, at 65 FR35597, on June 5, 2000. The statutory 90 -day appeal period, which was initiated on the second newspaper publication date cited above, has ended. The proposed BFEs for your community were appealed during that time. All technical data submitted in support of the appeal have been evaluated and the appeal has been resolved. Therefore, the BFEs for your community are considered final. The final rule for BFEs will be published in the Federal Register as soon as possible. 2 Several comments were submitted from various communities regarding the Preliminary and Revised Preliminary FIRM. Therefore, our Map Coordination Contractor will send you a Proof Copy of the final FIRM in mid -April for your review prior to the scheduled effective date of August 23, 2001. The formal appeal period is over. Appeals have been resolved as appropriate and the new FIRMs are essentially finalized. Only major floodplain delineation changes can be accepted at this time. Due to the time constraints involved, we will accept changes during a 5 -day review period following initial receipt of the Proof Copy FIRM. Approximately three weeks before the effective date, FEMA will send you the final printed copies of the FIRM and FIS report. Because the FIS establishing the BFEs for your community has been completed, certain additional requirements must be met under Section 1361 of the National Flood Insurance Act of 1968, as amended, within 6 months from the date of this letter. Prior to August 23, 2001, your community is required, as a condition of continued eligibility in the National Flood Insurance Program (NFIP), to adopt or show evidence of adoption of floodplain management regulations that meet the standards of Paragraph 60.3(d) of the enclosed NFIP regulations (44 CFR 59, etc.) by the effective date of the FIRM. These standards are the minimum requirements and do not supersede any State or local requirements of a more stringent nature. It must be emphasized that all of the standards specified in Paragraph 60.3(d) of the NFIP regulations must be enacted in a legally enforceable document. This includes adoption of the current effective FIRM and FIS report to which the regulations apply and other modifications made by this map revision. Some of the standards should already have been enacted by your community in order to establish initial eligibility in the NFIP. Your community can meet any additional requirements by taking one of the following actions: 1. Amending existing regulations to incorporate any additional requirements of Paragraph 60.3(d); 2. Adopting all of the standards of Paragraph 60.3(d) into one new, comprehensive set of regulations; or 3. Showing evidence that regulations have previously been adopted that meet or exceed the minimum requirements of Paragraph 60.3(d). Communities that fail to enact the necessary floodplain management regulations will be suspended from participation in the NFIP and subject to the prohibitions contained in Section 202(a) of the Flood Disaster Protection Act of 1973 (Public Law 93 -234) as amended. In addition to your community using the FIS to manage development in the floodplain, FEMA will use the FIS to establish appropriate flood insurance rates. On the effective date of the revised FIRM, actuarial rates for flood insurance will be charged for all new structures and substantial improvements to existing structures located in the identified SFHAs. These rates may be higher if structures are not built in compliance with the floodplain management standards of the NFIP. The actuarial flood insurance rates increase as the lowest elevations (including basement) of new structures decrease in relation to the BFEs established for your community. This is an important consideration for new construction because building at a higher elevation can greatly reduce the cost of flood insurance. K To assist your community in maintaining the FIRM, we have enclosed a Summary of Map Actions to document previous Letter of Map Change (LOMC) actions (i.e., Letters of Map Amendment, Letters of Map Revision) that will be superseded when the revised FIRM panels referenced above become effective. Information on LOMCs is presented in the following four categories: (1) LOMCs for which results have been included on the revised FIRM panels; (2) LOMCs for which results could not be shown on the revised FIRM panels because of scale limitations or because the LOMC issued had determined that the lots or structures involved were outside the SF14A as shown on the FIRM; (3) LOMCs for which results have not been included on the revised FIRM panels because the flood hazard information on which the original determinations were based are being superseded by new flood hazard information; and (4) LOMCs issued for multiple lots or structures where the determination for one or more of the lots or structures cannot be revalidated through an administrative process like the LOMCs in Category 2 above. LOMCs in Category 2 will be revalidated through a single letter that reaffirms the validity of a previously issued LOMC; the letter will be sent to your community shortly before the effective date of the revised FIRM and will become effective 1 day after the revised FIRM becomes effective. For the LOMCs listed in Category 4, we will review the data previously submitted for the LOMA or LOMR request and issue a new determination for the affected properties after the revised FIRM becomes effective. When the FIRM and FIS report are printed and distributed, your community will receive only those panels that present flood hazard information for your community. We will provide complete sets of the FIRM panels to county officials, where they will be available for review by your community. Once the FIRM and FIS report are printed and distributed, the digital files containing the flood hazard data for the entire county can be provided to your community for use in a computer mapping system. These files can be used in conjunction with other thematic data for floodplain management purposes, insurance purchase and rating requirements, and many other planning applications. Paper copies of the FIRM panels may be obtained by calling our Map Service Center, toll free, at 1- 800 - 358 -9616. Copies of the digital files may be obtained by calling our Map Assistance Center, toll free, at 1- 877 -FEMA MAP (1- 877 - 336 - 2627). In addition, your community may be eligible for additional credits under our Community Rating System if you implement your activities using digital mapping files. FEMA makes flood insurance available in participating communities; in addition, we encourage communities to develop their own loss reduction and prevention programs. Through the Project Impact: Building Disaster Resistant Communities initiative, launched by FEMA in 1997, we seek to focus the energy of businesses, citizens, and communities in the United States on the importance of reducing their susceptibility to the impact of all natural disasters, including floods, hurricanes, severe storms, earthquakes, and wildfires. Natural hazard mitigation is most effective when it is planned for and implemented at the local level, by the entities who are most knowledgeable of local conditions and whose economic stability and safety are at stake. For your information, we are enclosing a copy of a pamphlet describing this nationwide initiative. For additional information on Project Impact, please visit our website at www.fema.gov /impact. 4 If your community is encountering difficulties in enacting the necessary floodplain management measures, we urge you to call the Director, Mitigation Division of FEMA in Denton, Texas; at (940) 898 -5127, for assistance. If you have any questions concerning mapping issues in general or the enclosed Summary of Map Actions, please contact Ms. Katie Paulson of our staff in Washington, DC, either by telephone at (202) 646 -2585 or by facsimile at (202) 646 -4596.
