Land Acquisitions Manager 2557 SW Grapevine Parkway, Suite 100 Grapevine, Texas 76051 Re: Notification of changing the location, widening, narrowing and reconfiguration of the 1% (100 -Year) annual chance floodplain. Dear Mr. Robbins, The Flood Insurance Rate Map (FIRM) for a community depicts land which has been determined to be subject to a 1% (100 -year) or greater chance of flooding in any given year. The FIRM is used to determine flood insurance rates and to help the community with floodplain management. Dowdey, Anderson & Assoc., Inc., is applying for a Conditional Letter of Map Revision (CLOMR) from the Federal Emergency Management Agency (FEMA) on behalf of Toll Brothers, Inc., to revise FIRM No. 48113C0155 J for Dallas County for the proposed Carter Addition Phase III development along Grapevine Creek. Your company, Toll Brothers, Inc., is proposing to revise the FIRM to reflect the Carter Addition Phase III development. The revision to the FIRM will result in relocation, widening, narrowing and reconfiguration of the 1% annual chance (Zone AE) floodplain for Grapevine Creek. The Conditional Letter of Map Revision will result in: 1. The floodplain modifications will widen and narrow the 100 -year floodplain. This letter is to inform you of the revision of the 1% annual chance (Zone AE) floodplain and the regulatory floodway on your property for the Carter Addition Phase III Development. We would like to obtain your acceptance of revision of the 1% (100 -year) annual chance (Zone AE) floodplain revision on your property for the Carter Addition Phase III development. Please sign and date the provided copy of this letter to signify your acceptance and return it to Dowdey, Anderson and Associates, Inc. by mail, email or fax at 972 - 931 -9538. If you have any questions or would like to review the CLOMR request do not hesitate to call. If you have any questions or concerns about the proposed changes to the FIRM or its effects on your property, you may contact me at 972 - 931 -0694. Sincerely, Casey Ross, P.E., CFM I, Rob Paul, accept the re- delineation of the 1% annual chance floodplain as described above.
