RE: Village at Cottonwood Creek Section VI
Construction Plans
Dear Mr. Hovas:
The City of Coppell has received and reviewed the referenced plans and has the following
comments to offer:
1. Need to show additional R.O.W. in the Pedmore Drive cul-de-sac on the plat.
2. Top of curb elevation shown on Sheet 10 doesn't match the elevation shown on Sheet
11.
3. The drainage area on the east side of the development shown on the drainage area map
(Sheet 15) does not match what is shown on the lot grading plans. Also, the Copper
Stone Development (east of this development) does not include any drainage from Lots
71-72, Block A in their drainage calculations. If you proposed that the lots will drain
to the east then someone should contact Bill Anderson with Dowdey Anderson and
Associates at 931-0694 to determine if the alley will be able to convey any additional
drainage.
4. Upon reviewing the drainage calculations, Ken Griffin, City Engineer and myself
request that since you are simulating time of concentrations, a more realistic time of
concentration of 10 minutes should be used.
5. If Copper Stone does not develop before this development then Lots 73-80, Block A will
not be allowed to be developed until the alley in Copper Stone is constructed and
approved.
6. On Sheet 17, the plan view of Line B shows a 7x7 box culvert while the profile shows
a 84" RCP.
7. The following are comments made on Sheet 19:
a) Locate the inlet on Gifford Drive so that it will not create a driveway conflict for Lot
59. Show the easement for existing 90" RCP along Gifford Drive. Also, address the
comment regarding the reason for the extra storm drainage easement shown in Alley E.
b) Submerge the 90" RCP into the proposed lake as much possible to avoid anybody
from entering the pipe.
8. Comments made on Sheet 20:
a) Because of the realigning of the existing drainage channel on the northwest side of
the development it may be necessary to construct a guardrail on Coppell Road showing
the limits of the proposed stone wall.
b) The profile for Line G shows a Hike & Bike sidewalk in the channel. If this is the
case, the location would need to be discussed with Rick Wieland, Park Superintendent
at 462-8495.
9. Howard Pafford, Utility Superintendent, has the following comments to be addressed:
a) Sewer line F should be tied in with the flow. Also, you are showing to connect to
an existing 15" sanitary sewer line. This line is an 8" sewer line. Contact Howard
Pafford at 462-8495 if you have any questions.
b) On Hardwick Court the water line should be into existing 12" water line on Parkway
Blvd.
10. On the grading plans, Fairland Circle appears to have a low point (Sheet 26).
There are various other minor comments throughout these plans. Once these comments have
been addressed, three revised sets and the mark up plans should be resubmitted to the City for
review. If you should have any questions concerning these comments, please feel free to contact
me at your convenience.
Sincerely
Michael A. Martin, E.I.T.
