Construction Plan Review Comments
Dear Mr. Stroh:
The City of Coppell has reviewed the referenced plans and has the following comments to offer:
General Notes —
The approved site plan should be included in the civil plan set.
Sheet 3 (Grading Plan) —
1. Revise arrows in driveway onto Royal Lane to reflect that left turns are not allowed.
2. Verify that the elevations of the driveway approach onto Royal Lane meets the City of
Coppell's Specifications.
3. You may need to verify the accuracy of the benchmark used. The city maintains a list of
current benchmarks, one of which is very close to this site. Contact Scott Latta at 972 -304-
3683 for more information.
4. How will northbound trucks access the truck courts on the south side of the development?
From Gateview Blvd.?
Sheet 4 (Paving Plan) —
1. If it is your intention to not install a lime subgrade beneath your paving, a written request for
a waiver must be made to the City. The request is generally approved for private paving as
long as the strength of the concrete is increased to 4000 psi or the thickness is increased by
one inch. Any paving within the public right -of -way still requires a flex -base subgrade.
2. Include "and the City of Coppell's Standard Specifications and Subdivision Ordinance" in
Paving Note #4.
3. Revise Paving Note #5 to indicate the Texas MUTCD.
4. Indicate the turning radii for both driveways. If trucks will access the site primarily from
southbound Royal Lane, a large turning radius may be necessary. This may affect the
location of the inlet and fire vault.

Sheet 5 (Drainage Plan) —
1. Clarify the limits of Drainage Area C.
2. The drainage area data table is faded and difficult to read.
3. Verify that the load rating of the proposed grate inlet and concrete upper stage can withstand
large truck traffic.
4. How deep is the water surface elevation of Drainage Area B exiting the site? Will it overtop
the concrete flume and flow onto Royal Lane?
5. Extend the rip -rap and indicate that it is to be grouted.
Sheet 6 (Utility Plan) —
1. Either increase the size of the fire line along the east side of the property to 8" and extend it
to serve the fire hydrant OR increase the size of the easement to be a uniform shape.
2. Show the Fire Department Connection (FDC) and verify its location with the fire marshal.
3. Provide a detail of the water meters /fire vault connection along Gateview.
4. Indicate the size of the proposed sanitary sewer manhole along Gateview.
Sheet 7 (Erosion Control Plan)
Consider relocating the construction entrance so that both driveway approaches can be
constructed at the same time.
Sheet 8 (Construction Details)
All details in the construction plans that are included in our Standard Details should be removed
from the plans. The only details to be included in these plans are details that are revised and
specific to this project. The contractor is required to have a copy of the City of Coppell Standard
Details on the job site at all times during construction.
Once the necessary corrections have been made, please return this marked -up set and two sets
of revised plans to the City for review. If you have any questions or need any additional
information, please contact this office at your convenience.
Sincerely,
Teresa Turner, E.I.T.
