Dear Mr. Hennessey:
The City of Coppell has received the referenced plans and has the following comments to offer:
o
9.
10.
11.
12.
13.
Provide a cover sheet with the legal description on the next set of review plans.
Provide a paving and subgrade design on the site plan.
Show the proposed changes relating to access to the property from the adjacent owner to
the south.
Remove the landscape and irrigation plan from the civil construction plans. Provide the
landscape and irrigation plans separately to the Building Inspection Department for
approval.
On the grading plan, do the grades for the easternmost landscape area include the future
design of the deceleration lane and sidewalk.
Coordinate with the adjacent property owners to the north and south regarding matching
paving grades for the fire lane and also the shared access on the east side of the property.
On the drainage area map, provide a 10' minimum curb inlet at the low point on the west
side of the property.
Provide storm drain profiles for the 21" RCP and hydraulic calculations.
Use a minimum time of concentration of 10 minutes and an intensity value using TP-40.
On the utility plan, provide an 8" cross, valve and plug with one joint of line at the
location shown on the plans. Also, show the vault location and size and provide a double
check with the 1" meters.
Tap the 8" water line for the domestic and irrigation meters instead of the fire line.
Install a manhole instead of the double cleanout outside of the future deceleration lane in
the utility easement.
The 12" water line on Denton Tap is in the pavement and not at the location shown on the
water and sewer plans.
There are various other minor comments throughout these plans. Once these comments have been
addressed, the marked up plans along with two revised sets of 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 304-3682.
Sincerely,
Atul Patel, E.I.T
