advised ~at d~ng ~e eo~se of eons~etion, ~e Ci~ ~11 enforce our St~d~d Det~ls,
reg~dless of what det~ls ~e sho~ wi~in ~e plus.
2. The most recent plat should be provided with the cons~ction plus.
3. Sheet C2.7 - ~e proposed 5' fl~e should be disch~ged into ~e existing ~inage way at
~gle ~ opposed to 90°.
4. Sheet C2.9 - there is a cogent to relocate a pond. ~e relocation appe~s to be on top of
8" water line. Is this note ~ e~or, or is there actually going to be a pond built at t~s
location?

9. It appe~s ~ though the proposed 8" water line ~o~d ~e new Se~ice Center is to be
cons~cted ~ a fire line only. To be a fire line only ~d not cont~n~ within ~y easement,
you do need to provide vaults ~ it co~ts to the existing 8" wat~ line. If it is proposed to
be public, then ~ easement should be shorn on the proposed plat. Also, if it is to be public,
it should be extended to yo~ sou~em prope~y line so ~at the prope~y south of the school
c~ tie onto it in ~e ~t~e.
10. ~en ~e const~t ch~ging on ~is school site be~een buil~ngs, fields, iffigation ~d fire

This can be easily accomplished by providing a vault and a high/low compound meter on the
two 8" water lines that connect to the 12" water line in Wrangler Dr. By making this
modification, all the interior water lines, irrigation lines, etc. would then be private. This
would eliminate the need for all the meters onsite to the various buildings and irrigation
systems. It would also eliminate the need for the double check and vault for the fire lines
going to the buildings. Once you have evaluated this comment, please contact this office to
discuss options further.
11. A valve should be installed on the relocated portion of the existing 8" water line, which will
allow portions of the existing line to be isolated for repair or maintenance while still
providing fire protection to the sprinkler system for the Service Center and water to hydrants
around the Service Center.
12. Need to provide a Fire Department connection for the Service Center.
13. All water lines crossing either existing or proposed sewer lines should be constructed per
TNRCC rules. This may require encasing either the water or the sewer line depending on the
situation.
Coppell Middle School West 2001 Addition/Renovations -
1. Need to include the correct plat.
2. Sheet C2.9 - our plans show the existing 8" water line to be located beneath the new
proposed drive approach on the west side of the parking lot. This may require relocating the
existing water valve.
3. Sheet C2.1 - the proposed meter for the new concession should be relocated closer to the
main line, and included within either the existing easement or a new easement before the plat
is filed. Again, all crossing of existing with proposed water and sewer lines should be as per
TNRCC rules.
Once all changes have been made, please resubmit these marked-up plans and two sets of
revised plans to the City for review. If you have any questions, please contact me at (972) 304-
3686.
