This is in response to the request for a conditional Letter of Map Revision
(LOMR) for fill adjacent to Tributary G-1 of Grapevine Creek in vicinity of
Bethel School Road and Bethel Road in the City of Coppell, dated September 9,
1991.
We have completed an inventory of the items you submitted to support this
request. The results of our inventory are s%~mmarized on the enclosed "Data
Request Checklist": all the items indicated by an #X# in Column 1 are needed
before we will begin our review; items indicated in Column 2 have already been
received. If only items in Column 2 are noted, no additional items are
required at this time; therefore, we will begin our review. However, addi-
tional items may be requested at a later date.
The Federal Emergency Management Agency (FEMA) has implemented a reimbursement
procedure to recover cost~.associated with reviewing proposed projects, thus
reducing the expense to taxpayers. The initial fee, if indiCated on the
checklist, is the minimum charge associated with our reviewing a project of
this type. However, additional costs could be required after review and
before issuing a conditional LOMR depending on the complexity of the review
required. You will be notified of the estimated total processing cost if it
is anticipated that, due to the extent of the review required, the total cost
will exceed $1,500.00. In that situation, our review would be suspended
pending written authorization from you to proceed.
Any items indicated in Column 1 of the checklist should be submitted within 30
days to the following address:
Federal Emergency Management Agency
Federal Insurance Administration
Office of Risk Assessment
500 C Street, SW, Room 422

Requested.
Please note that any initial fee already submitted will be applied to this
request only if we receive all items indicated on the checklist within 90 days
of the date of this letter. After 90 days, the request will be treated as an
original submittal and will be subject to all submittal/payment procedures,
including the initial fee. However, should you wish to withdraw your request
for a conditional LOMR at this time, you may submit a written request for
return of data and reimbursement of any initial fee already submitted by
writing to the address given above within 90 days.
To provide assistance in preparing the required data, we have enclosed a copy
