Cambridge Phase 2-CS 960110The Honorable Tom Morton Mayor, City of Coppell P.O. Box 478 Coppell, Texas 75019-0478 Federal Emergency Management Agency Washington, D.C. 20472 JAN 1 01996 IN REPLY ~FER TO: ~ ~ C~e No.: 9~53C Co~~: 'Ci~ of Cop~ll, Te~ Co~ No.: 480170 Map P~el Aff~: ~10 E T-218-65-CN Dear Mayor Morton: This is in response to a letter dated November 9, 1995, from Mr. Rusiy Spiars, P.E., Spiars and DeOtte, Inc., requesting that the Federal Emergency Management Agency (FEMA) determine whether the following property is located in a Special Flood Hazard Area (SFHA), an area that would be inundated by a flood having a 1-percent chance of being equaled or exceeded in any given year (base flood). This property will be elevated by the placement of fill. property_ Description: Proposed Tracts A and B, Estates of Cambridge Manor, Phase H C0mmuni_ty and State: City of Coppell, Texas The legal descriptions of the parcels mentioned above are as follows: proposed Tract A: BEGINNING at the southwest comer of Lot 9, Block C, of the Estates of Cambridge Manor, on the north line of Castle Creek Drive; thence N 89°39'52' W, 175.00 feet along the south line of LOt 9; thence S 58°34'17" E, 106.50 fget; thence S 00020'08" W, 575.00 feet; thence west, 30.00 fe~t; thence N 15042'35" W, 320.00 feet; thence N 64'37'05" W, 163.30 feet; thence N 00'22'46' E, 253.51 feet to the POINT OF BEGINNING. Proposed Tract B: BEGINNING at a half-inch iron rod on the north line of Deforest Road at the southwest comer of Lot l, Nettie Long Addition; thence N 00°20'26." E, 180.00 feet; thence S 89041'49" W, 291.42 feet; thence S 00005'38" W, 180.00 feet; thence S 89041'49" W, 291.42 feet; thence $ 00'05'38" W, 180.00 feet; thence N 89'41'49" E, 292.93 feet to the POINT OF BEGINNING. All fees necessary to process this Conditional Letter of Map Revision (CLOMR), a total of $280, have been received. On November 22, 199:5, we received all information necessary to process Mr. Spiars' request. After comparing this information to the National Flood Insurance Program (NFIP) map for the City of Coppell, Texas, we determined that Tracts A and B described above would be located in an SFHA if fill is placed as proposed. This conditional determination is based on the site plan, entitled "Grading and Erosion Control Plan, Estates of Cambridge Manor, Phase H, Coppell, Texas," prepared by Spiars and DeOtte, Inc., dated August 15, 1995. The proposed elevation of the lowest ground on a parcel must be at or above the base flood elevation (BFE) for the property to be conditionally outside the SFHA. Because the proposed elevation of the lowest ground within the parcels described above, 450 feet, is lower than the BFE, 452.2 feet, the property would be within the SFHA. These elevations are referenced to the National Geodetic Vertical Datum. This conditional determination is based on the flood data presently available. Should you wish to resubmit this request for a CLOMR, Section ?2.? of the NFIP regulations provides a period of 90 days from the date of this letter for resubmission of revised data without repayment of review fees. Data submitted after 90 days, or data which show that the project has been significantly altered in design or scope, other than as necessary to respond to the f'mdings made in FEMA's original determination, will be subject to all submittal payment procedures described in Section ?2.4, including the initial fee. Portions of Parcels A and B mentioned above would meet the minimum requirements for the removal of the SFHA designation from a vacant parcel of land under Paragraph 65.5(a)(3) of the NFIP regulations. Because this request included no proposed elevation data for planned structures, the SFHA designation would not be removed from any planned structures. The request also did not present data about additional grading of the parcel, and therefore raises concerns with the elevations for the completed parcel. For any structure built in an area elevated by fill after the date of the earliest NFIP map showing the area in the SFHA, Paragraph 65.5(a)(4) of the NFIP regulations requires that both the lowest adjacent grade (lowest ground touching the structure) and the lowest floor (including basement) be at or above the BFE. FEMA will determine if the existing or planned structure is located outside the SFHA upon receipt of all necessary elevation data for the structure. This response is based on the minimum criteria established by the NFIP. State and community officials, based on knowledge of local conditions and in the interest of public safety, may set higher standards for construction in the floodplain. If the State of Texas or your community has adopted more restrictive and comprehensive floodplain management criteria, those criteria take precedence over the minimum Federal criteria. This letter does not relieve Federal agencies of the need to comply with Executive Order' 11988 on Floodplain Management in carrying out their responsibilities and providing federally undertaken, financed, or assisted construction and improvements, or in their regulating or licensing activities.
