RE: Texas Bank Addition, Lot 1 Block A
Construction Plan Review Comments (Second Submittal)
Dear Mr. Wooten:
The City of Coppell has reviewed the referenced plans and has the following comments to offer:
Plat -
1. Please provide a 25'x 25' utility easement centered on the fire vault.
2. The curb inlet designated as "to be relocated" is in a drainage easement that was dedicated in 1988.
If you relocate that inlet onto the adjacent Lot 2 of Block A, we will need a similar easement to
cover the construction and permanent drainage structure that will be within that platted lot.
General Comment -
I. Check the wording on your seal (as placed on Sheet C3), I believe it says Licensed ,Professional
Engineer rather than Registered Professional Engineer.
Sheet C4 (Site Plan) -
1. Install the ADA accessible ramp on the north side of the drive approach to Denton Tap Road and
leave the sidewalk to be constructed when Lot 2 is developed.
Sheet C6 (Grading Plan) -
1. Construction of the inlet on adjacent Lot 2 is shown within the platted lot, and an easement shall be
provided as indicated above.
Sheet C7 (Paving Plan) -
1. The sidewalk to be constructed along Denton Tap Rd. should be located a minimum of 4' offback
of curb, and may meander to miss the existing utility poles.
2. The concrete thickness shown for the pavement section exceeds our minimum standards when 6"
lime stabilized subgrade is used. This is acceptable to us, but you could build the heavy-duty
concrete as 6" reinforced and the standard duty (parking spaces) could be 5" thick with a 6" lime-
stabilized subgrade.
Sheet C8 (Utility Plan) -
1. This drawing needs to be looked at from a quality control standpoint. There is a lot of confusion
between line sizes and labeling, e.g. you show 2 one-inch irrigation meters, and no domestic, etc.
Please review this sheet, and correct any discrepancies.
2
The FDC needs to be within 50' of a fire hydrant. That can either be run out to the existing hydrant
in Van Bebber Dr. or the new hydrant onsite as shown on the plan.
If you construct a new hydrant onsite, you will need an 8" connection to the 16" ~vaterline and run
that 8" connection up to where the fire hydrant tees off. From there the lead could be 6" up to the
building for your sprinkler system. I've made some notes on the plans, but if you decide you don't
need the new hydrant, disregard those comments.
Please make the necessary changes and submit these marked-up plans and two sets of revised plans
to the City for further review. If you have any questions, please contact this office at your
convenience.
Sincerely,
Keith R. Marvin, P.E.
