RE:
JP No. 88009; Construction Plans;
Parkway Boulevard (West); Coppell, Texas
Dear Taryon:
Enclosed are the sets of construction plans for proposed
improvements in Parkway Boulevard and the High School Access Road
reviewed by Ginn, Inc. and provided to us on January 6, 1989.
Also enclosed is one set of the current construction plans for
Site Grading; Water, Sanitary Sewer and Storm Drainage; and
Paving Improvements for these proposed roadways as revised in
accordance with Ginn's and other Development Review Committee
comments. Revisions are described below.
1. Site Grading Plans
Variance requested for street lights is deleted. ABQ
has agreed to provide street lights with plat approval.
A variance is requested for use of a 360 foot radius in
the High School Access Road. A separate letter is
provided requesting variances.
City permission to allow earth moving equipment to
cross Right-of-Ways, as stated in Note 5 on the plat,
is essential for ABQ to proceed with construction of
the streets shown theron at this time. At a meeting on
January 6, 1989, it was my understanding that Mr. Kevin
Peiffer of Ginn, Inc., upon learning that "owner" as
used in this note refers to ABQ Development
Corporation, withdrew his objections to this note as
long as the conditions for the City granting this
permission as stated in Note 5 are maintained.
Proposed grades in Parkway Boulevard at the
intersection with Denton Tap Road have been coordinated
with grades for the Parkway Boulevard turnout designed
by Ginn, Inc. Also an inlet is added on the south side
of Parkway Boulevard to remove storm water runoff from
the street just west of the intersection.

Water, Sanitary Sewer, and Storm Drainage Plans
The future 16-inch water line in Denton Tap Road north
of Parkway Boulevard is proposed to be located in the
Denton Tap Road Right-of-Way. The proposed 8-inch
sanitary sewer adjacent to Denton Tap Road is located
eleven feet from the west Right-of-Way line. Therefore
the distance between the future water main and the
currently proposed sanitary sewer is in excess of
minimum requirements.
Proposed water mains under Denton Tap Road at the
Parkway Boulevard intersection will be shown on the
water and sanitary sewer layout sheet in accordance
with Ginn's plans.
The Drainage Area map has been revised such that almost
all the runoff from area A-4 (now indicated as area
C-i) will be picked up in Storm Drain Line C prior to
entering Denton Tap Road. A note is added indicating
that storm sewer Stubout D-3a must be extended and Dick
up runoff in area D-1 upon development of sites in this
drainage area.
Construction plans for Storm Drain Line C and a short
extension of existing Stubout D-3a will be submitted by
Wednesday, January 11, 1989. This drawing will be
included as Sheet No. 8 of the Plans.
The size of the box culvert in the high school site is
corrected on the Drainage Area Map.
