Re: Devonshire Estates
Coppell Road Drainage and Sidewalk
Dear Ms. Daneshmand:
We have reviewed the construction plans for the Devonshire Estates Drainage
Improvements and Sidewalk along Coppell Road prepared by Carter & Burgess,
Inc. Our review comments are as follows:
1. It is our understanding that the Drainage Improvements and Sidewalk plan
was proposed as an interim solution to providing pedestrian access from
Devonshire to the new Coppell Elementary School immediately south of this
addition. We 9~er no objections to this plantin general. However, we
do recommen~t'~his~Y~n'be~6c~f~s'~ ihferim ~°~ti°~-6~iy and
c0~siderati0n be given t~"~r6vih~'d6pp~ii'-~a-tecif¥ S~a~a&rds both
aiong'the'~°ntage Of this addition and the'-~hool property as soon as
2. The typical section shows a railroad t~e retaining wall 3.0 ft to 4'-6"
~n height. R de~ai~ed engineering design along with specificet£ons ~s
required for any retaining wall in excess of 4 feet in height.
3. ~n our meeting a~ the pro,oct s~te on October 3, ~99~, it was &etermined
that the sidewalk and screening wall would be shifted approximately 4
feet east along Lot 1, Block B to accommodate the existing storm drainage
headwall at Halifax Drive. This plan should reflect that revision.
Shifting the screening wall and sidewalk approximately 4 feet east along
Lot 1, Block B requires a sidewalk easement for the City of Coppell and a
screening wall easement dedicated to the Homeowner's Association. These
easements may be submitted as separate instruments.

A landscape plan along the sidewalk was discussed during previous
meetings with the Developer. It was our understanding that landscaping
was to be required between the sidewalk and the drainage channel. These
plans do not address landscaping.
The prints indicate that these plans have been modified to reflect
construction records. This note is not appropriate at this time and
should be removed from the plans.
The Developer should submit either the Engineer's construction estimate
or the contract amount for the drainage channel and retaining wall work.
The 2% construction inspection fee should be paid in full prior to
beginning work on this project. We are enclosing a copy of a Draft
Letter for your use in requesting payment of the construction inspection
fee.
We have discussed most of these issues with the Developer's Engineer and it is
our understanding they are working to revise the plans. We recommend that the
drainage channel and retaining wall plans not be approved for construction
until the above listed comments are addressed. We are available to discuss
this review at your convenience.
Sincerely,
Enclosures
