RE:
JP No. 88009; Final Plat;
Parkway Boulevard (West); Coppell, Texas
Dear Ms. Bowman:
In order that roadways can be constructed that will provide
public access to the new Coppell High School, our client, ABQ
Development Corporation, has directed our firm to prepare the
subject plat and construction plans for these improvements. The
plat provides for the dedication of Parkway Boulevard for
approximately 800 feet west of Denton Tap Road and for a roadway
from Parkway Boulevard to the High School property line. In
addition, right-of-way is platted adjacent to the west side of
Denton Tap Road in order to provide a total of 100 feet of right-
of-way width for this improved roadway.
Street alignments and right-of-ways shown on the Final Plat are
in accordance with the approved Preliminary Plat of these
roadways. On behalf of our client, the City of Coppell Planning
and Zoning Commission and City Council are requested to approve
two variances indicated on the Final Plat and described below.
Use of 360 foot centerline radius
School Access Road.
curves in the High
The High School Access Road was designed in accordance
with the alignment already under construction (and now
completed) within the High School property. The
centerline radius of this roadway as it is constructed
within the High School site up to the High School
property line is 360 feet. Referring to the plat
drawing, this radius was extended northeasterly onto
ABQ property. The alignment is then reversed back to
the north to form a 90~ intersection with proposed
Parkway Boulevard.
Since deceleration is required as traffic exiting the
High School approaches the "T" intersection with
Parkway Boulevard, and due to the relatively short
distance between Parkway Boulevard and the High School
property line, conditions in the High School Access

Road will not be suited to the higher speed limits that
the radius lengths specified in the City Ordinance are
designed to accommodate. Therefore use of 360 foot
centerline radius in the High School Access Road is
requested. This radius is in accordance with the
radius used in the approved Preliminary Plat.
2. Delay of Landscaping in Parkway Boulevard
ABQ Development Corporation wishes to assist the
Coppell Independent School District in providing
roadways to the new High School. However due to
current adverse market conditions, ABQ requests that
the City of Coppell grant a variance to delay
installation of landscaping until adjacent properties
are platted. This will allay the financial burden of
installing and maintaining landscaping until market
conditions warrant such expenditures.
ABQ will provide a two-inch water service to the median
area for future irrigation facilities. In addition ABQ
will seed the median with Bermuda grass, as well as the
adjacent parkways, to control erosin.
On behalf of my client, I would like to thank the City staff for
the assistance they have provided in the preparation of this
plat. If you have any questions, please call.
Sincere~ /
