CF-Andrew Park 1-CS 930521Federal Emergency Management Agency Washington, D.C. 20472 18 1993 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO; Case No.: 93-06-091R The Honorable Mark Wolfe Mayor, City of Coppell P.O. Box 478 Coppell, Texas 75019 Community: City of Coppell, Texas Community No.: 480170 104 Dear Mayor Wolfe: This is in response to a letter dated January 5, 1993, from Mr. Kenneth M. Griffin, P.E., City Engineer, City of Coppell, to the Federal Emergency Management Agency (FEMA) regarding the Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) for the City of Coppell. Mr. Griffin requested that FEMA evaluate the effects that proposed improvements to Andrew Brown Jr. Community Park along Denton Creek would have on the preliminary FIS and FIRM. All data required by FEMA to evaluate this request were submitted by Mr. Griffin with his letter dated January 5, 1993. In his January 5 letter, Mr. Griffin certified that this project is sponsored by the City of Coppell for public benefit, and therefore, is in accordance with Section 72.5 of the National Flood Insurance Program (NFIP) regulations. The fees associated with the review of this Conditional Letter of Map Revision (CLOMR) have been waived. We have reviewed the data submitted with respect to the data used to prepare the preliminary FIRM for the City of Coppell. We believe that if the proposed project is constructed as described in the report entitled "Request for Conditional Letter of Map Revision on Denton Creek in Coppell, Texas, Andrew Brown Jr. Community Park for the City of Coppell, Texas," prepared by Albert H. Halff Associates, Inc., dated December 1992, then a revision to the FIRM and FBFM would be warranted. This CLOMR is based on the data used to prepare the December 18, 1991, preliminary FIRM. The preliminary FIRM must become effective before a revision can be issued. Changes, if any, to the data used to prepare the preliminary FIRM before it becomes effective may affect this CLOMR determination. Upon completion of the project and receipt of the data listed below, we will make a final determination on revising the FIS report and FIRM. Certification that all fill placed in the currently effective 100-year floodplain and below the proposed base flood elevation (BFE) is compacted to 95 percent of the maximum density obtainable with the Standard Proctor Test method issued by the American Society for Testing and Materials (ASTM Standard D-698) for all areas to be removed from the 100-year floodplain · As-built plans, certified by a registered professional engineer, of all proposed project elements · As-built HEC-2 hydraulic analysis of the 100-year flood and 100-year floodway · Copy of the public notice distributed by the community stating the community's intent to revise the floodway, or a statement by the community that it has notified all affected property owners and affected adjacent jurisdictions After receiving appropriate documentation to show that the project has been completed, FEMA may initiate a revision to the FIS report and FBFM. Because the BFEs would change as a result of this project, a 90-day appeal period would be initiated, during which community officials and interested persons may appeal the revised BFEs based om scientific or technical data. Because the existing floodway may need to be modified as part of the revision, we would require a letter from you stating that the community would adopt and enforce the modified floodway. If the State of Texas has jurisdiction over either the floodway or its adoption by your community, we would need a copy of your letter to the appropriate State agency notifying it of the floodway modification and a copy of a letter from that agency stating its approval of the modification. This response to Mr. Griffin's request is based on minimum floodplain management criteria established under the NFIP. Your community is responsible for approving all proposed floodplain development, including this request, and for assuring that the necessary permits required by Federal or State law have been received. State and community officials, based on knowledge of local conditions and in the interest of human safety, may set higher standards for construction or may limit development in floodplain areas. If the State of Texas or the City of Coppell has adopted more restrictive or comprehensive floodplain management criteria, those criteria take precedence over the minimum NFIP requirements. Should you have any questions regarding this matter, please contact the Chief, Natural and Technological Hazards Division of FEMA in Denton, Texas, at (817) 898-5127, or Mr. John Magnotti of my staff in Washington, DC, at (202) 646-3932, or by facsimile at (202) 646-3445. cc,* Mr. Kenneth H. Griffin, P.E. City Engineer City of Coppell Sincerely, Chief, R~sk S Federal Insurance Administration Ms, Jean Hansen Albert H. Halff Associates, Inc.
