Re;
Preliminary Hydraulic Analysis of Proposed Residential Development
on the East Side of Grapevine Springs Creek
Dear Ken:
As per our telephone conversation on October 10, 1995, I am sending this letter summarizing thc
conclusions of our conversations:
The proposed excavation (shelf on the west bank) shall be stabilized to avoid
erosion.
The valley storage theoretical gain and/or the actual loss shall be allowed by the
City of Coppell regardless of the reviewing consultant's recommendations;
providing the railroad bridge is the control structure, thus protecting the existing
development to the south.
Once the zoning approval and final subdivision layout has been completed, a formal FEMA
submittal shall be prepared. Please contact me prior to Friday, October 13, if you disagree with
the contents of this letter; otherwise, I will consider this letter to be an accurate summary of the
conclusions of our telephone conversation.
Thank you for your cooperation.
Sincerely,
GRAHAM ASSOCIATES, INC.
