RE: Summit at the Springs Second Construction Review
Dear Mr. Dowdey:
The City of Coppell has received and reviewed the referenced plans and has the following comments
to offer:

B.
2. On the paving plans, show the brick pavers required per Streetscape Plan.
3. Install barrier free ramps at the subdivision entrance. Also, use the no parking sign shown
between medians as required per Subdivision Ordinance.
4. A minimum of 60' spacing between medians is required per Subdivision Ordinance.
5. Provide 4" yellow pavement striping with yellow pavement markers at 30" o.c. at the
locations shown on the plans.
6. The paving contractor shall construct the barrier free ramps instead of the home builder at
time of home construction.
7. On sheet 3 of the paving plans, since A > 1.0, provide a 100' minimum vertical curve at
the location shown on the plans.
8. On the drainage area map, use the correct intensity values if you are using TP40, and a
"C" value of 0.65 instead of 0.5. Also, show the drainage easements.
9. Provide information regarding the ditch on Bethel Road, i.e. prof'fle, elevation shots that
the proposed Q from drainage area "11" is flowing to.

17. On line "I" profde, the 21" R.C.P. and the 24" R.C.P. is not there anymore according to
the storm sewer plans.
18. On the grading plans, some type of slope protection may be required in the bend of
Grapevine Creek for lots 45 and 2X. Also, provide a cross section of the ditch along Bethel
Road.
There are various other minor comments throughout the 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 contact me
