RE: Coppell High SChool, Final Plat (Resubmittal)
LOCATION: West of Denton Tap Road and south of the future extension
of Parkway Boulevard.
APPLICANT:
Coppell Independent School District
TRANSPORTATION:
Please refer to the attached Traffic Access Evaluation,
prepared by Barton-Aschman Associates, Inc.
HISTORY:
Subject site of the final plat resubmittal for Coppell
High School is located on 49.9 acres of land. The original
application was filed with the City in November of 1986.
The City Council considered the preliminary plat on January
13, 1987; however, Council directed the applicant to work
with Staff to address unresolved issues. Major areas of
concern, such as traffic access, water and sewer issues,
traffic studies and variance requests, were worked out with
Staff, and the Coppell Independent School District plat was
considered by the City Council on January 27, 1987, and
approved with conditions. (Please see attached City
Council minutes of January 27, 1987).
Final plat application was approved by the City Council on
September 8, 1987, with the following conditions:
That the building height be granted a variance to
allow for a proposed height of the structure to
fifty-two feet (52').
That the variance on the lighting be approved with the
use of a blinder to cur the sideways spillage of the
light onto adjoining property owners.
That the variance from the required two thousand
(2,000) parking spaces be decreased to one thousand
two hundred fifty (1,250).
That five inches (5") of concrete on a prepared
subgrade be allowed for the entire parking area with
no gravel parking areas.
ITEM ~ 13
That as many trees as possible will be left on the
west with a six foot (6') chain length fence being
constructed on the outside of the trees along the west
property line. Dr, Melvin Gross, who was in the
audience the night the preliminary plat was approved
by Council, stated that lie would be willing to donate
any property to the school that would be required to
put his fence on the outside area of the trees, and
this fence would also be constructed along the
southern property line up to Oak Trail. The gate to
this property would be for emergency use only. The
gate to this property on the south side of the
property would be considered to be for emergency
traffic only and extra emphasis on shrubbery would be
followed along the south property line from the chain
length fence east to the school's eastern most
property line.
e
That the fees be waived as requested and the City
Manager enter into negotiations with the Coppell
I.S.D. for some "in-kind" training of City employees.
Staff contacted the applicant's representative to inform
them that the final plat would have to be submitted to the
City for signatures within six months from the date of City
Council approval. The Comprehensive Subdivision Ordinance
requires that if a final plat is not submitted for
signatures within six months, resubmittal shall be required.
Current subdivision regulations will apply to the
resubmittal, and the Development Review Committee has
reviewed this item for conformance to all City standards.
The following is a list of revisions since the approval of
the final plat on September 8, 1987:
Added alley R.O.W. dedication along south side of
school.
2. Named access drive as "High School Access Drive".
0
Swapped parcels of property near the northeast corner
of subject with ABQ Development Corporation.
4. Added utility signature block.
5. Indicated Lot 2, as R.O.W. dedication.
Applicant is requesting approval of a final plat
(resubmittal), and along with the variances which were
approved by the City Council on Septelmber 8, 1987. Staff
has no objections.

Evaluation for the Proposed Coppell High
This memorandum presents the findings and conclusions of a traffic
study conducted for the proposed Coppell High School in Coppell, Texas. The
site for the proposed school is located west of Denton Tap Road, south of
the proposed Parkway Boulevard, and north of Willow Lane. The site location
is illustrated in Figure 1.
The purpose of this study is to evaluate the access requirements to the
school. As presently proposed, access to the site would be from the Parkway
Boulevard extension, via a connecting'driveway, ~o the northeast corner of
the site. The proposed access configuration is shown in Figure 2. This
study will determine the size requirements of the access driveway as well as
the Parkway Boulevard extensior~
The conditions governing the configuration of the proposed access
roadways are dependent upon the trip generation characteristics of the
school. The primary variable affecting these characteristics are the number
of students enrolled.
The school site is planned to accommodate a maximum of 2500 students.
This enrollment figure is expected to occur in the year 2005. To facilitate
the planning of roadway requirements during the period from school opening
(expected in 1988) to 2005, discussions were held with school district staff
to establish the estimated enrollment for target years between 1988 and
2005. The estimated enrollments are as follows.

Standard trip generation rates contained in the Institute of Transportation
Engineers (ITE) publication entitled Trip Generation and from Barton-Asc/mman
files were applied to the expected enrollments to determine the traffic that
will be generated by the school. The trip generation rates used for the
proposed school are given in Table 1. Table 2 indicates the total number of
trips that can be expected during the morning and afternoon peak hours of
school activity.

The lane requirements for the proposed access roadways were analyzed by.
evaluating the demand, capacity and level of service on the access drives.
The level of service for roadways can range between level of service "A" and
"~', with level of service "A" representing an optimal and uncongested free-
flowing condition and level of service "P' representing a heavily congested,
forced flow condition. The acceptable design level of service (LOS) for
most large cities if IDS "[7'. However, for this analysis, the design level
of service was assumed to be IDS "C".
The capacities used in this analysis were obtained from the North
Central Texas Council of Governments ~CTCC~) and arethecapacitiesusedin
their regional transportation model. For purposes of this study, the
following capacitieswereused.

Based on these roadway lane capacities, the lane requirements for the
access roadways were determined for each year. The results are given in
Table 3.

The results indicate that two-lane roadways will handle the expected
school generated traffic at an acceptable level of service until, based on
the estimated enrollments, sometime after 1995.
It should be noted that the analysis is based on school generated
traffic only. The lane requirement on Parkway Boulevard will be greatly
affected by other traffic on the roadway after it is completed between
Denton Tap Road and Coppell Road, as proposed. The analysis also does not
include traffic generated bya 6000 seat stadium proposed for the school
site.

RE: Street Dedication
Dear Mr. Ratliff:
This letter is to inform you that it will be my recommendation
to the Board to agree to dedicate the 24-foot wide strip of
land between our property and Denton Tap Road to the City as
a street right-of-way. The Board ha given me every
indication that there will be no problem with the vote,
although the Board will not meet to act on that matter until
May 8.
I should, however, also make note that there are presently
no funds available to use on construction of the street. As
we had discussed earlier with City staff, it would be our
plan to consider construction of a road for bus usage when
the second phase of the school is begun.
You might recall that a traffic study was done in Conjunction
with the construction of Parkway Boulevard and the access
road to the school property. That study showed that two
lanes would be adequate access to the school until further
additions were done. We are, however, constructing both sides
of Parkway Boulevard and are constructing a four lane,
44-foot wide street section from Parkway to the school. We
are comfortable, and traffic studies show that this street
should be adequate for many years.
We thank you for working with us throughout this project and
if there are any other questions, let me know..
Very truly yours,
Vonita White,
Superintendent

Dear Mr. Doyle:
As requested by the City through the surveyor, Ayers & Associates, we are
submitting this letter to list those public utility items which have been
revised from the original plat and plan approval to this date.
To the best of our knowledge, the following items have been revised:
Add approximately 1000 LF 6" fire line to extend fire protection
to the west side of the stadium.
Adjust alignment of 60" storm drain north of the north property
line to avoid existing sanitary sewer manhole present in the
creek. The easement for the facility was revised accordingly.
Lower 10' x 8' box culvert from Sra. 7+70 to Sta. 15+20 to
accommodate developer to the east.
Delete box culvert headwall at the southeast corner of the site
and construct rock rip-rap transition in lieu of headwall for
ease of future southerly extension of the box culvert.
Item No. 1 was reviewed and approved by the City prior to construction.
Item Nos. 2 thru 4 were reviewed and approved by the City and coordinated
in the field with Steve Morton, Chief Development Inspector. To the best
of our knowledge, the above represents the revisions to the plans made
during construction and which were approved by City staff prior to
construction of said revisions. If you have any questions, please feel
free to call. Sincerely,
TEAGUE NALL AND PERKINS~.. ~

Item 16:
Consider approval of a final plat and variances for CoppelIi
High School, at the request of Coppell I.S.D., on property
located approximately 1000 feet west of Denton Tap Road, and
approximately 1300 feet north of Sandy Lake Road.
Date of Planning and Zoning meeting - August 20, 1987
Decision of Planning and Zoning Commission - Approved (6-0)
Planning and Zoning Coordinator Taryon Bowman made the presentation to
the Council. She stated that this is a request of a final plat for
Coppell High School on 49.9 acres of land. Several variances have been
requested such as building height, lighting, parking, parking surface,
and screening wall. The school district has also requested a waiver for
the payment of water and sewer availability fees, sewer contract fees,
water tap fees and construction permit fees. Ail DRC comments have been
addressed, therefore, staff has no objections. Mr. Jim Boughton of
SHWC Architects made the presentation to the Council on behalf of the
applicant. Due to a conflicting function this same night, there was no
one from the Coppell I.S.D. or School Board present. Following
discussion, Councilman Smothermon moved that Council approve the final
plat of Coppell I.S.D. for the Coppell High School and that this
approval be subject to the conditions set forth in the preliminary plat
as reiterated below:
That the building height be granted a variance to allow for a
proposed height of the structure to fifty-two feet (52').
That the variance on the lighting be approved with the use of a
blinder to cut the sideways spillage of the light onto adjoining
propert~ owners.
That the variance from the required two thousand (2,000) parking
spaces be decreased to one thousand two hundred fifty (1,250).
That five inches (5") of concrete on a prepared subgrade be allowed
for the entire parking area with no gravel parking areas.
That as many trees as possible will be left on the west with a six
foot (6') chain length fence being constructed on the outside of
the trees along the west property line. Dr. Melvin Gross, who was
in the audience to night the preliminary plat was approved by
Council, stated that he would be willing to donate any property to
the school that would be required to put this fence on the outside
area of the trees and this fence would also be constructed along
the southern property line up to Oak Trail. The gate to this
property would be for emergency use only. The gate to this
property on the south side of the property would be considered to
be for emergency traffic only and extra emphasis on shrubbery would
be followed along the south property line from the chain length
fence east to the school's eastern most property line.
That the fees be waived as requested and the City Manager enter into
negotiations with the Coppell I.S.D. for some "in-kind" training of City
employees. Mayor Pro Tem Stanton seconded; motion carried unanimously
with Mayor Pro Tem Stanton, Councilmen Wilkerson, Pettijohn, Morton,
Smothermon, Cowman and Wolfe voting in favor of the motion.
