Dear Mayor Morton:
This is in response to a letter from Mr. Rusty Spiars, P.E., Spiars & 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 f'dl after the date of the earliest National Flood Insurance Program (NFIP) map showing
the area in the SFHA.
property_ Description: Proposed Tracts A and B, Estates of Cambridge Manor, Phase H
Communi_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, Estates of Cambridge Manor,
on the north line of Castle Creek Drive; thence S 89°08'02" E, 126.60 feet; thence
S 66°42'02" E, 128.16 feet; thence S O1 °22'22" E, 570.28 feet; thence west, 25.00 feet;
thence N 15°42'35" W, 320.00 feet; thence N 64037'05" W, 163.35 feet; thence
N 03°12'19" E, 203.80 feet; thence west, 10.00 feet; thence N 00°22'46" E, 50.00 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 1, Nettie Long Addition; thence N 00°20'26" E, 7.00 feet to the POINT
OF BEGINNING; thence N 00°20'26" E, 169.00 feet; thence S 89°41'49" W, 277.42
feet; thence S 00°05'38" W, 169.00 feet; thence N 89°41'49" E, 278.15 feet to the
POINT OF BEGINNING.
All fees necessary to process this Conditional Letter of Map Revision (CLOMR) were received with Case
No. 96-06-053C. This letter revises the determination made in the CLOMR dated January 10, 1996.
2
On January 11, 1996, we received additional information necessary to process this request. After
comparing this new information to the NFIP map for the City of Coppell, Texas, we determined that
Tracts A and B described above would not be located in the 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 II, Coppell, Texas,' prepared by Spiars & DeOtte, Inc., dated
January 10, 1996. Our final determination will be made upon receipt of a copy of this letter, a copy of
the final plat with recordation data, and certified as-built information showing the elevations of the lowest
ground on each tract. In addition, the enclosed form, entitled "Certification of Fill Placement," must be
returned, signed and dated by a registered professional engineer, an accredited soils engineer, or the
community's NFIP permit official.
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 base
flood elevation. FEMA will determine if the existing or planned structure is located outside the SFHA
upon receipt of all necessary elevation data for the structure.
Please note that the NFIP is non-taxpayer funded and its expenses are paid by policyholders. Therefore,
to minimize the financial burden on the policyholders while maintaining the NFIP as self-sustaining,
FEMA has implemented a procedure to recover costs associated with reviewing and processing requests
for modifications to published flood information and maps. Therefore, an initial fee of $225, which
represents thc minimum charges associated with a request of this type, must be submitted before we can
process your revision request. Payment of this fee shall be made in the form of a check or money order
in U.S. funds made payable to the National Flood Insurance Program, or by credit card payment. The
payment is to be forwarded to the following address:
Federal Emergency Management Agency
Fee-Collection System Administrator
P.O. Box 3173
MERRIFIELD VA 22116-3173
Please note that this property could be inundated by a flood greater than the base flood or by local
flooding conditions not shown on the NFIP map. Flood insurance is available at a reduced cost for
properties located outside the SFHA. Also, although we have based our determination on the flood data
presently available, flood conditions may change or new information may be generated that could
supersede this determination.
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.
If you have any questions or if we can be of further assistance, please contact Ms. Agnes De Coca of our
staff in Washington, DC, either by telephone at (202) 646-2746 or by facsimile at (202) 6464596.
