ITEM 6
COMPREHENSIVE
PLAN:
The Comprehensive Plan shows low density single-family development on
this parcel.
ANALYSIS:
Because churches are identified as being compatible with single-family
land use, this proposal meets the objective of our Comprehensive Plan.
A close look at the site plan reflects the appropriate brick screening walls,
adequate yard dimensions, and landscaping which appears to meet the
criteria of the Streetscape Plan.
Our major development concern with this request relates to traffic access,
circulation, and patterns of traffic generation. We had strongly
recommended that this church work with the Coppell Independent School
District - the land owner adjacent on the west - to provide vehicular
access from this site to Samuel Boulevard, probably parallel to the existing
alley. However, we have recently learned that CISD will not allow access
across their school site. We also have concerns relative to where
MacArthur Boulevard access is to be provided, the potential need for a
deceleration lane, and concerns about alignments with existing median
openings. Because of these concerns, a traffic study which will
satisfactorily address these issues was recommended and eventually
provided.
Other issues regarding drainage easements, fire hydrant requirements,
water and sanitary sewer issues will be addressed at subdivision platting.
Suffice it to say here that these concerns must be satisfactorily addressed
at platting.
If we receive satisfactory answers to our traffic-related concerns outlined
above, and the site plan, landscaping, screening provision, circulation, and
aesthetic concerns are satisfactorily addressed, approval would be in
order.
ALTERNATIVES:
1) Approve the zoning request

The new Church of Jesus Christ of Latter-Day Saints facility
in Coppell is being planned. A traffic study of the proposed
plan and its effect on the area is required by the City of
Coppell. The details of the study are given in the following
pages.
The traff£c study includes a review of the site plan, a survey
and review of the traffic situation on MacArthur Boulevard at
the church's activity time, traffic manuevers to enter and
leave the site, the traffic to be expected from the site and
recommendatioms of steps to be taken to enhance the traffic
flow £eto and out of the site.
The results of

SITE PLAN
The location of the site for the new church dictates
that its access is limited to MacArthur Boulevard. The
plan shows one drive which is made up of two one-way
pavements, both 24' wide, separated by a landscaped
median 10' wide. The drive extends into the site
approximately 20' to a 24' wide circulation aisle which
extends across the front of the church building and
connects to 90° parking areas along both the east and
west sides of the building. There is no entrance on
the front or north side of the building, but there are
entrances on both the east and west sides, as well as
at the rear. A large parking area is provided to the
rear of the building.
The proposed site plan shows a deceleration lane across
the entire MacArthur Boulevard frontage of the site. A
sidewalk is also shown across the site, which connects
to an existing walk along the south side of MacArthur
to the east of the site. Notations have been made on
the site plan of negotiations with the Coppell Indepen-
dent School District to obtain an easement across the
school frontage for the deceleration lane and also an
easement across the south side of the school tract to
gain access to Samuell Road.
AREA ACCESS/CONDITIONS
The site for the new church is located in the north
eastern portion of the City of Coppell. The two primary
roads used to approach the site are MacArthur Boulevard
and Samuell Road.
MacAurthur Boulevard According to the City of
Coppell Major Thoroughfare Plan given in the Roadway
Functional Classifications and Design Standards for
the City of Coppell, MacArthur Boulevard is a Major
Arterial and is planned to have three lanes in each
direction with a 17' median. At this time, it is
operating as a four lane road with two lanes in
each direction. It has two roadways 22' wide and a
36' median. By design, when completed, MacArthur
Boulevard is planned to have a capacity of 35,000
trips per day.
MacArthur is the eastern most arterial in the City
of Coppell. It is also important from a regional
perspective as it provides a connection from SH 183
in Irving on the south to Lewisville on the north.
In Coppell, it connects with Sandy Lake Road approxi-
mately 3/4 mile south and Beltline Road another
mile south of Sandy Lake Road. These roadways
connect to IN 35E, Carrollton and points east.

SITE ~..,,.
III.
In the area of the church site, MacArthur has a 60'
median opening opposite the east property line of
the site which serves the residential street, which
intersects MacArthur from the north. A left turn
lane with 80' of storage is provided for eastbound
traffic. There is another 60' median opening 422'
west. A left turn lane with 80' o~ storage is pro-
vided for westbound traffic. These geometric
features are shown in the drawing and also the
approximate location of the site.
Samuell Road In the City of Coppell Thoroughfare
Plan, Samuell Road is indicated as a Collector
street with parking permitted on both sides. It is
a reinforced concrete roadway with curb and gutter
and the pavement is 44' wide B-B. Samuell Road has
a total length of approximately one mile. It runs
north and south from Sandy Lake Road to MacArthur
Boulevard. At the present time, there is a temporary
span-wire mounted traffic signal at the intersection
of Samuell and Sandy Lake. There is a four-way
stop control at the intersection of Samuell Road and
Parkway Boulevard. A permanent traffic signal is
now under construction at the intersection of Samuell
Road and MacArthur Boulevard. This signal will be
the closest major traffic control device to the
site of the new church.
The area around the proposed church is rapidly develo-
ping. To the north and west of the site are completed
residential subdivisions. Between the site and Samuell
Road to the west is an undeveloped school site. The
site is bordered on the east by a residential tract
that is now under development. Further to the south
and east there are several rapidly developing residential
subdivisions.
Traffic approaching the site from the south on MacArthur
Boulevard will have to make a U-turn at the median
opening west of the church and a right turn into the
drive. To return to the south, a simple right turn out
of the drive is all that is necessary. Those approaching
the site from the north on MacArthur need only make a
right turn into the drive. To return, a right turn
from the drive, followed by a U-turn at the median
opening is the most obvious route. An analysis of the
U-turn manuevers is given later in this study.
U-TURN AND DRIVE OPERATION
Traffic approaching the site from the southeast on
MacArthur Boulevard will make a U-turn at the median
opening opposite the school site. They will then make

a right turn into the drive. When departing the site,
they can simply make a right turn onto MacArrhur. Those
approaching from the northwest will enter the site by
making a right turn into the drive. When departing,
they may turn right from the drive and enter the left
turn lane at the intersection median opening to make a
U-turn.
Departing traffic will have to cross both eastbound
lanes to enter the left turn lane, so large gaps in
eastbound traffic on MacArthur will be important,. The
inbound traffic will have to cross both lanes of east-
bound traffic to make their U-turn and turn into the
drive. A deceleration and right turn lane will give
them a refuge prior to actually making their right
turn.
TRAFFIC GENERATION
Based on information given in the January 1991 5th
Edition of Trip Generation, published by the Institute
of Transportation Engineers, the traffic generated
during the peak hour of church activities is 239 trips.
This figure is calculated based on the proposed 25,506
feet2 size of the new church.
CHURCH DEMOGRAPHICS AND ACTIVITY SCHEDULE
The new church is planned to be used by two separate
congregations. They will attend servcies at the new
facility at different times on Sundays. One group will
be made up of church members who live in Coppell and
southern Lewisville and Flower Mound. They will meet
at the new church from 8:00 a.m. to 11:00 a.m. The
other group will be members living in Carrollton who
will meet at the new church from 1:00 p.m. to 4:00 p.m.
It is estimated that the first group will have 254 mem-
bers and the second will have 208 members.
SITE IMPACT ANALYSIS
In order to determine the effect that the new church
will have on MacArthur Boulevard, a traffic impact
analysis was completed. The analysis involved a study
of (1) the effectiveness of the proposed driveway, (2)
the effect that the U-turns at the two median openings
will have on MacArthur traffic, (3) the need for and
design of a deceleration lane on MacArthur Boulevard,
and (4) the need for access from the site across the
school site to Samuell Road. The analysis assumes a
worst case situation. In this case, that means the
traffic volume for the church is that calculated from
-3-
the Trip Generation Manual. The inbound to outbound
assumption is that 50% of the peak hour traffic is
inbound and 50% outbound. With the two existing median
openings on MacArthur, it will not be possible to
construct one to serve the church traffic directly.
The proposed driveway will operate with only right
turns inbound and right turns outbound. Both the
inbound and outbound flows will operate in a single
file. The large (24') inbound lane will allow a
smooth turn and allow traffic to clear the right
lane of MacArthur Boulevard quickly. The outbound
lane is also 24' wide, but this may not be desirable.
A lane that wide will encourage exiting traffic to
line up two abreast. This can cause visibility
problems for the right vehicle. In addition, both
cars may attempt to make their right turns at the
same time. Consideration should be given to reducing
the width to the exit lane to 14' to 16' The
median island proposed in the drive will eliminate
any conflict between inbound and outbound traffic.
The size and design of the drive will allow it to
accomodate the expected traffic volumes easily.
U-turns on a divided thoroughfare can cause prob-
lems. The potential for problems is effec:ed by
several factors, including the width of roadway
available for the turning manuever, the availability
of a protected storage lane to wait to make the
turn, the visibility of traffic approaching from
the opposite direction and the volume and regularity
of opposing traffic. On MacArthur Boulevard, in-
bound traffic to the site can make use of the
existing westbound left turn lane for the opening
west of the site. The outbound traffic can make
use of the existing eastbound left turn lane for
the opening at the east boundary of the site.
Visibility to the east along MacArthur is clear for
over 1000' To the west, there is a gentle rise,
but approaching traffic can be seen from west of
the Samuell Road intersection.
In order for the largest private auto, i.e., van,
pickup, etc., to make a U-turn, a minimum width of
48' of pavement is needed. On MacArthur Boulevard,
the width of pavement from the right side of the
left turn lane to the right curb of the opposing
lanes is measured at 58' The required turn can
therefore be made with relative ease.
The primary concern when making a U-turn is with
traffic coming from the opposite direction. At an
intersection such as the one at the eastern boundary
-4-
of the church site, there is also concern with
vehicles entering from the cross street. A survey
was done of the existing traffic along MacArthur
Boulevard. The amount of traffic east- and westbound
was counted and also the various turning movements
at the intersection were recorded. The survey was
done on Sunday to cover the beginning and ending
times for the services for the two church groups.
The Sunday services are the only times that the
whole group attends at one time. There is no time
when both groups are at one service. The results
of the survey are shown in the following table and
drawing. The drawing shows the various movements
that were recorded.
The survey shows that the through movement volumes peak
at just over 60 vehicles per direction in a 15 minute
period. If the traffic were distributed evenly over
time, there would be a maximum of four vehicles per
minute or one vehicle every 15 seconds. Since the
traffic was actually observed passing in groups of from
two to five vehicles, there are often large gaps between
cars. These gaps will allow easy flow of traffic in
and out of the driveway and also little conflict with
traffic making U-turns at either of the median openings.
In the future, there may be some increase in traffic on
MacArthur as the residential areas to the south and
east build out, but it is doubtful that the Sunday
volumes will increase to the point of creating a problem
from the church. In addition, the traffic signal that is
under construction at the intersection of MacArthur
Boulevard and Samuell Road can be expected to provide
gaps in the traffic approaching from the west. The
church traffic, either exiting at the driveway or U-
turning at the western median opening, will be able to
take advantage of these gaps.
The need for a deceleration lane and right turn lane to
serve a driveway is generally demonstrated by a large
inbound traffic volume and/or a congestion situation
that may create a queue on the street approaching the
drive. The inbound traffic volume during the peak hour
of the church activity should be easily accomodated by
the 24' wide entry aisle of the drive. The only way
that queueing might occur is if an oneite congestion
situation were to make it impossible for entering traf-
fic to clear the drive. If a very large percentage of
the congregation were to arrive at virtually the same
time, this might occur. If a deceleration lane is pro-
vided, it should be 11' to 12' wide and have the same
design as the left turn lanes at the median openings,
i.e., 80' of storage length and 120 of transition.

'VIII.
The need for an additional accessway to the site across
the school site from Samuell Road would be demonstrated
in the same way as the decleration lane, if the proposed
drive on MacArthur Boulevard could not handle the expec-
ted traffic into and out of the site. Another consi-
deration might be the elimination of a serious U-turn
hazard. In the proposed situation, the expected traffic
volume should not create an operational problem at the
drive. In addition, the information given above indi-
cates that U-turns which must be made to approach the
site can be safely done by making use of the existing
median openings and left turn lanes.
CONCLUSIONS AND RECOMMENDATIONS
The information developed in this study leads to a num-
ber of conclusions and recommendations.
Conclusions:
The proposed site plan will provide smooth circulation
of on-site traffic.
The traffic generated by the proposed church can be
adequately served by the single drive proposed.
Existing and expected traffic on MacArthur Boulevard
will provide large gaps in traffic for entering and
departing traffic. The eastbound gaps can be enhanced
by the new traffic signal.
The U-turns necessary to approach and leave the site
can be safely made.
A deceleration and right turn lane is not indicated by
expected traffic volume, but will enhance entering
traffic.
The need for access across the school tract to the west
of Samuell Road is not indicated by the expected traffic,
especially with the deceleration/right turn lane.
Recommenda~ion8:
The proposed driveway design should be adjusted to pro-
vide a 14' to 16' exit lane to eliminate the possibility
of a double right turn movement,
The deceleration/right turn lane should be designed
with 80' of storage and 120' of transition.
Members of the congregation who live south, east or
west of the site should be requested to approach the
site from Samuell Road onto MacArthur and return to the
south on MacArthur to eliminate the need for as much of
the U-turning traffic as possible.
