Dear David:
As per our telephone conversation, I am transmitting bluelines of the channel
improvements and drop structure certified as of the date of the "record drawings ". This
should provide all of the necessary data required to complete the detailed review of this
project for issuance of a final letter of map revision.
Please let me know if there are any additional questions. Both the City of Coppell
and the developers in this area are anxious to complete this project in time to be
incorporated into the current Coppell Flood Insurance Study Update.
Yours very truly,
ALBERT H. HALFF ASSOCIATES, INC.
