First Construction Review Comments
Dear Mr. Acker:
The City of Coppell has received and reviewed the referenced plans and has the following comments
to offer:
1. On the grading plans, the storm sewer and paving for Creek'view Drive has not been
constructed. See Creekview Drive construction plans by Rust Lichliter/Jameson.
The drainage area calculations table shows drainage area D-2 going out the driveway. The
grading plans do not correspond to this. Which plan is correct? Currently, drainage is
flowing to the existing Y-inlet. An inlet may need to be constructed in this area to pick up
the Q if the Y-inlet is remOved.
3. The drainage area shown on the Creekview Drive plans does not correlate with what is
shown on your plans. Please address this issue.
On sheet Al.0, the note for detail 1 shall specify the subgrade to be 6" lime stabilized or
flexbase. Any variance to the requirement shall be submitted to the City Engineer. Also,
please see the City of Coppell Standard Construction Details for all construction.
5. Please provide a plat on the next set of plans.
6. On the water and sanitary sewer plans, consider constructing a {~" sanitary sewer line
instead of a 4" sewer line due to the length of the sewer line. Contact Howard Pafford,
Water and Sewer Superintendent at 304-3551. Also, provide a cleanout for both sewer
services at the property line outside of paving. Also, show the fire lines on the water and
sewer plan. ,t
7. On the erosion control plans, hay bale the inlet at the location shown.
8. On sheet Al. 1, show the double check detector checks for the fire line after the tap off of
the City main.
9. On the fire. protection plan, provide the size for the water line on Creekview Drive. Also,
show the double check detector checks for the fire line after the tap off of the City main.
There are various other minor comments throughout the plans. Once these comments have been
addressed, the revised set of plans should be resubmitted to the City for review. If you should have
any questions concerning these comments, please contact me at 304-3682.
