RE: FEMA Case #92- 06 -110P, Elm Fork Trinity River, City of Carrollton, Texas
Dear Mr. Preusch:
1
As the Floodplain Administrator for the City of Coppell, Texas, I have received information
concerning fill that will be placed along the Elm Fork of the Trinity River at Sandy Lake Road.
The information provided shows that the fill will not increase the base flood elevation at any
cross section along the Elm Fork of the Trinity River. I spoke with Tim Tumulty, P.E., City
Engineer, for the City of Carrollton and Michael Boyd, of Nathan D.Maier, Consulting
Engineers, Inc., who prepared the study. It is my understanding, after reviewing the
information and speaking with the above referenced people, that all fill on this project is taking
place within areas of ineffective flow, thereby, not increasing the water surface elevations. The
City of Coppell offers no objections to the placement of fill in the areas of ineffective flow as
shown on the exhibits provided to the City of Coppell.
If you should have any additional questions or concerns please feel free to contact me at (214)
393 -1016 at your convenience.
Sincerely,
Kenneth M. Griffin, P.E.
City Engineer
