RE: Westhaven Subdivision (2"d submittal)
Dear Mr. Harris,
The City of Coppell has reviewed the referenced plans and has the following comments to offer:
General-
1. What is TXDOT's final response to the entrance median?
2. Provide copies of all approvals from TXDOT.
Grading Plan-
3. Has the creek side erosion been looked at? Is there any erosion protection planned for the
backside of the ponds facing the creek? The HOA will be responsible for any erosion issues
on this side of the creek. FYI, any erosion issues found on the opposite side of the creek on
adjacent property (The Mansions and Asbury Manors) should be their responsibility but
they might blame Westhaven Development. The contractor/developer should take
video/pictures of the creek bank for future reference.
Paving Plan-
4. The use of valley gutters is not permitted in Coppell per the Subdivision Ordinance. Remove
some of the text that still calls out valley gutters.
Drainage and Storm Drain Plan-
5. Double check all crossings.
6. Double check capacity calculations in the pipe.
7. Check the plan and profile stationing on the storm drain,they do not correspond.
8. The temporary grade to drain will need to have vegetation or erosion protection established.
9. The headwalls in Denton Creek should be tied to piers a minimum of 10' below the creek
bottom.
10. Add additional protection around the top of the headwall.

Miscellaneous-
11. Submit landscape plans as soon as possible to show the bridge and detail.
12. Include sheet C-45.
There may be additional comments throughout the plans that need to be addressed. The City of
Coppell has reviewed the plans for the referenced addition which will be approved with the
comments above addressed.
The City of Coppell requires three sets of final construction plans for its use; your office should
submit as many additional sets for stamping as is necessary for construction operations. All
contractors and subcontractors onsite must have a copy of the plans approved by the City of
Coppell along with a copy of the City's standard construction details.
All fees must be paid prior to release of this project for construction. The City charges a 2%
inspection fee for all private construction outside the building's footprint. This includes dirt
work, paving, storm drains, water lines, sewer lines, drainage pipes, etc. that are private. For all
installations in the public right-of-way or easement, the City charges a 4% fee. A check for
inspection fees made to the City of Coppell should be submitted to this office along with the
Construction Development Permit Application and a copy of the Construction Site Notice. For
your convenience a spreadsheet is attached to the permit application for use in calculating the
inspection fees. A copy of the contract(s) should be attached for verification purposes.
If you have any questions, please contact me at your convenience.
Sincerely,
Michae Garza,' .E.
