Comment Letter Dated: March 21, 2006
Vista Point II/Lot 4, Block A Construction Plan Review Comments
Dear Ms. La Mattina:
In response to your comment letter dated March 21, 2006, all issues have been addressed as
per your request with the following responses to your comments:
Site Paving Plan, C1.2
1. Include the City's lime stabilization requirement in the paving descriptions. If it is your intention to
not install a lime subgrade beneath your paving, a written request for waiver must be made to the
City. That request is generally approved for private paving as long as the strength of the
concrete is increased to 4000 psi or the thickness of the concrete is increased by one inch. Any
paving within public right-of-way still requires a lime subgrade. It is our intention to not install
a lime stabilized subgrade beneath the paving. The pavement has been increased to 4,000
psi concrete and a waiver request is attached for this item. There is no proposed paving
within the City right-of-way.
2. The sidewalk shown fronting the referenced site is located within the City of Lewisville. This was
permitted and inspected by the City of Lewisville. It is the developer's responsibility to satisfy the
requirements of the City of Lewisville. Acknowledged.
Drainage Area Map, C3.1
1. Runoff from drainage areas 081 is not in compliance with the overall drainage area map that
was approved for the site. Please indicate how flow from this drainage area will enter the
existing 18" stub at the northeast comer of the property and detail any temporary inlets or
measures that may be need to be constructed. We have specified a City standard 2'x2' drop
inlet at the end of the 18" to collect the drainage from area 081 per discussion during our
meeting on March 21.
Utility Plan, C4.1
1. The site infrastructure installed at Vista Point II under the construction plans called "Vista Point II,
Paving & Utility Improvements" engineered by Pacheco Koch and approved by the City of
Coppell was intended to form a utility framework for the subdivision. Basic water, sewer and
storm water stub-outs were provided to each lot. As each lot is prepared for construction,
developers will be required to meet the City's minimum standards for subdivision. By ordinance,
fire hydrants are required and should be spaced no more than 300 feet apart along the fire lane.
They should be located three to six feet behind the curb. We have adjusted the location of
the existing fire hydrant and added an additional fire hydrant at the northwest comer of the
lot per discussions with Tim Oates and yourself during our meeting on March 21.

hydrant and on the same side of the fire lane as the fire hydrant. FDC has been relocated to
the northwest comer of the property, remote from the building per discussions with Tim
Oates and yourseff during our meeting on March 21.
