Re: FEMA Map Revisions/Amendments
Dear Mr. GritTm:
Thank you for the notice to proceed with the FEMA map revisions at Andrew Brown Park (west), Deforest
Service Center, and the proposed Coppell Senior Citizens Center on Coppell Road.
We have ordered the effective Flood Insurance Study HEC-2 hydraulic models from the FEMA Project Library
for Denton Creek and Stream G- 1. FEMA will provide us with hard copies of the Denton Creek effective
models and a digital input file for the most upstream site along Denton Creek. As anticipated, because the
upstream end of Stream G- 1 is within an approximate study area, no FIS model is available for that site.
We received the proposed park improvements site plan from the MESA Design Group on January 19, 1996 and
are now setting up the field survey for that part of Andrew Brown Park West. To further proceed with our work,
please supply the following (if available):
· Digital topographic mapping for the City of Coppell (electronic file ~, 0cz.. ~O~
· Site plans for the various sites ~ ~O ~c~ ~~
· Plats for the sites ]
· Copies of pertinent Letters of Map Revision or Amendent
· Deeds / ~- fi~ t~Fl°' V
· Compaction test results
· Geotechnical studies I,~! ~2)c,~d~ ~,
We would like to meet with you or your designated project manager at your earliest convenience to gatherS^.
information and to discuss the project. Thank you very much for this opportunity to work with the City of[ [
