RE: Flood Study Ell Fork of Trinity River at Belt Line Road
Dear Mr. Morrison:
This letter is written as a follow-up to our conversation recently concerning the status of the
flood study for a Conditional Letter of Map Revision for the Elm Fork of the Trinity River
at Belt Line Road. That study has not been processed to FEMA, or to the Corps of
Engineers for their review of the CDC Permit.
Several items are still lacking on the study:
1. On the CDC form Part 1, the name of the CDC applicant and property owner
should be completed under Item 2, along with the project size.
2. On the CDC form Part 2, additional clarification needs to be provided on the
operation and maintenance of the proposed swale. At this time there ha~ been no
conversations with the City concerning this. There needs to be verification that the
property owner will maintain the swale because it is a component of the flood
study. Operation and maintenance plans for the channel should be provided.
3. Again, clarif'~cation needs to be provided on who will be Fl~i~talning this channel.
Your document states that the City of Coppell will perform inspections on 12-month
intervals. To date no commiUnent has been made along those lines.
4. You should provide either the 404 Permit or documentation that information
been sent to the Corps of Engineers for a 404 Permit.
If you should have any questions concerning these issues please feel free to contact this
office at your convenience.
Sincerely,
' .
