Re:
Final Plat and Construction Plans
Waterside Estates
Coppell, Texas
Gentlemen:
This is to advise you that our firm has received and reviewed
the above drawings for conformance with the City of Coppell
Subdivision Ordinance. We are recommending that the final
plat be placed on the upcoming Planning and Zoning Commission
agenda. Prior to the final plat being placed on the Coppell
City Council agenda, however, the following items need to be
addressed:
1. Street centerlines should have minimum radii of 425'
Curves 1, 2, 4, 5, and 6 are substandard.
2. The cul-de-sac at Cypress Court can be shortened if you
so desire.
3. For streets not intersecting at 90 degrees and at cul-de-
sacs, please show stationing of curb returns.
4. Please provide landscape plan conforming to City of
Coppell Streetscape Ordinance.
5. The 15 minute time of concentration for drainage does not
appear realistic. Please review drainage design for a
time of concentration of 10 minutes.
6. Prior to acceptance of the subdivision, the planned
improvements for Parkway Boulevard and lake spillways
should be in place.
7. How is the storm runoff from the west being handled? It
appears that an additional inlet at intersection of
Westwind Drive and woodmoor Drive is needed.
8. All sanitary sewer mains must be ductile iron or PVC.
Horizontal curves in sanitary sewers are not allowed.
9. All water and sanitary sewer mains shall be 8" diameter
minimum.
10. Please add fire hydrant at end of Cypress Court.
16135Pre,ton Road · Sui;c 106 · Dalla,.Texa, 75248 · Phone 214/386-6611
1. Clean-outs for sewer mains should be no further than 200'
from the nearest manhole.
12. Please provide 2 inch diameter flushing devices at capped
ends of water mains.
Please feel free to contact me concerning the above.
Sincerely,
V. Wankum, P.E.
