Re: Flood Insurance Study Preliminary Revision Letter
IA-RA-RS (100)
Dear Mr. Matticks:
This is in reference to your letter of September 22, 1988
regarding the subject Flood Insurance Study preliminary revision.
We are in the process of reviewing the subject preliminary study,
and will inform you of our results shortly. In the meantime, we
would like to clear up a problem discussed in the letter.
In a letter dated November 30, 1987, from Mr. Wayne Ginn, P.E.,
former City Engineer and Floodplain Administrator for our City,
we asked FEMA to revise the FIS to incorporate the effects of the
new Moore Road bridge across Grapevine Creek. Your September 22,
1988 letter caused us great concern by suggesting that we were in
violation of the National Flood Insurance Program regulations.
To correct this problem we asked Mr. Ginn to investigate the
matter.
Our understanding is that contact was made with Mr. Dave
Loshbaugh of Dewberry and Davis, Inc. (your technical consultant
for these matters), and Mr. Loshbaugh in turn contacted Mr. Matt
Miller of your staff. The result was a resolution to the matter
if the City would provide the following statements and
information:
The entire floodplain at the location of the apparent
violation (cross section 18600 in the "As-Built" HEC-2 model
submitted to FEMA) is owned by the City of Coppell, and the
City approves the approximate one half foot increase in the
floodway elevation.
2m
A modification to the floodway at this location showing the
floodway at the same width as the floodplain is acceptable
to the City. We will address this specifically in our
review of the FEMA Preliminary FIS revision to be completed
shortly.
