Construction Plans
Mr. Martin:
The above referenced plans have been revised based on the comments offered
in your letter of July 19, 1995. The following is a written response to the
comments offered:
1. Brick pavers will be installed with the construction of Old Coppell
Estates as shown on the revised plans.
2. Existing gas lines have been shown on proposed paving profiles.
3. A note has been added to the general paving construction notes on
sheet 3 referencing the Home Builder's responsibility to install
sidewalks and A.D.A. ramps as shown on the plans.
4. Note Number 7 of the paving construction general notes (Sheet
3) provides that all curb return radii shall be 25 feet unless
otherwise noted on the plans. This note was added in lieu of
individual radius notes to reduce plan congestion.
5. The radius leader for Hunterwood Court was extended to the
proposed right-of-way line.
6. Street names were revised and added to the drainage area map.
7. All storm headwalls were extended to the rear property lines.
8. Concrete rip-rap was added to the end of proposed headwalls as
shown on the plans for permanent erosion control.
