Dear Mr. Littleton,
The City of Coppell has reviewed the referenced plans and has the following comments to offer:
General -
1) Cover: Add legal name to cover page as that is how the project is tracked in Engineering.
2) Plat: Would it be possible to cross hatch the floodway on the plat?
3) General Notes: Paving requires #4 bars on 18" oc.
4) Paving Plan:
a) Wouldn't you want to connect the sidewalk near the NE corner of the building to the
sidewalk along the street?
b) Looks like missing a hatch for an area of paving.
5) Wall Plan Profile: Provide engineered plan in the Civil set with the next review set.
6) Grading Plan:
a) Check the contour tie-ins near the bridge.
b) Label the floodplain line.
7) Existing DAM: Label the cfs entering the pipes.
8) Storm Drainage Plan/Profile
a) Line A: Check your HGL — appears to have jumps in locations where there wouldn't be
any.
b) Line C: Flip the profile direction. Confusing to have north point down on the sheet.
9) Water/Wastewater Plan:
a) Fire hydrants to be located 3-6ft from the back of curb.
b) FDC shall be installed in accordance with City Details.
Please make the necessary changes and submit these marked -up plans and two sets of revised
plans to the City for review. If you have any questions, please contact me at your convenience.
Sincerely,
George S. Marshal , P.E.
