Ken,
Ron Morrison sent us the file that he received from the GIS department there at the city to see if we could convert
it to a CAD file for him to work with. We have tried to convert it here in our office and we have not been
successful. We can get the contours to come in, but we can not get the elevations to work, all of the contours are
set to an elevation of zero. We have contacted the GIS department to see if they could help and they gave us a
list of instructions, but it did not help. Is there any way that we can come down to the city to purchase a CD of the
topo maps? If the maps are too large, I have a 40 gig portable drive that we can use. Any help that you can
provide would be greatly appreciated.
Thanks
Steven R. Homeyer, P.E.

Ken:
We are doing a small study for Steve Homeyer who represents the owners of 224 - 228 Hollywood Drive
Coppell. The owners want to move their fences back to reclaim a portion of their yards. This area is in the
floodplain and they will need to do an H&H study to determine what impacts the fence will have. We
understand that they basically need to show a wall section in the model where they want to place the fence and
then move it back to where there are no impacts on the floodplain. We have a few questions in this regard:
Does the City have Topographic maps for this area.
We have sent to FEMA for the most recent model for the Elm Fork Trinity. This will be used to model
existing conditions and Fence Conditions.
Please let me know the City rules for fences. Such as:
Must we consider the fence as a blockage and all area on the Residence side of the fence as
ineffective flow.
Are there other considerations that must be addressed such as CDC requirements.
Thank you for your help.
Ron
