DR9305-CS 920428MEMO
TO: Steve Goram, Director Of Public Works
FROM: ~ ~'~ Kenneth M. Griffin, P.E., City Engineer
SUBJECT: Grapevine Springs Park
DATE: April 28, 1992
On April 28th, I contacted FEMA and talked to Mr. Dell Greet concerning
the reclamation that Dallas County is proposing for Grapevine Creek. I
had previously left phone messages, but those had not been returned. Mr.
Greer indicated that if Dallas County was going in and replacing some
minor erosion that had taken place since the Corp of Engineer's took their
cross-sections, then FEMAwould not have a problem with restoring the bank
to its original configuration.
However, the plans from Dallas County indicate that at Section II they are
replacing about 150 X 8 foot section to reclaim the portion of the creek
that has eroded over time. Also, at Section III, they are replacing about
100 X 10 foot section. Mr. Greer was very concerned that this type of
reclamation could change not only the width of the floodway but the water
surface elevation in this area. Mr. Greet indicated that to be in
compliance, Dallas County would need to go through the types of flood
studies that a typical developer in Coppell would have to go through.
This would be a study of the existing conditions and a study that shows
the proposed fill condition. This fill is proposed in a designated
floodway of the City of Coppell. Therefore, if the proposed study showed
any increase at all in the water surface elevation, this project would be
denied by the City of Coppell.
Mr. Greer did welcome Dallas County to contact him at (817) 898-5138 if
they had any questions concerning this.
If you should need any additional information, please feel free to contact
me at your convenience.
