Drainage Improvement Options for Skaggs Addition
You should be aware that a Ms. Jenkins has contacted our office
and was extremely upset about the drainage problems associated with
this project and the impact to her property. I have requested that
Shohre Daneshmand, our Acting City Engineer, contact her and advise
her and her neighbors of the item on your Agenda and the proposed
solutions. Ms. Jenkins and other neighbors may be in attendance
at your Council meeting.
Ms. Jenkins has implied that there has been damage to her home;
therefore, we may receive a claim for damages. Due to this
possible claim, please use some caution in your comments as to
responsibility for the problem.

Option ti is constguctioa of a 10' by 8' box culvert and would cost
approzinataly $728,000. The contract between Skaggs Dovelogmsnt and the
City obligates Skaggs for $345,000, leaving a difference of 8383,000.
In Option #2 the cost of co~___structioa is $534,000 with the contract ~aking
Skaggs responsible for $345,000, leaving a difference of $189,000.
In option #3 the financial obligation by Skaggs exceeds the coastruction

Connell Skaggs Drainage Improvement Options
We have reviewed the above referenced drainage improvement options
as prepared and proposed byConnell Development's Engineer and have
the following comments.
Option #1, Construction of a 10' x 8' box culvert is the best
alternative based on staff's review and recommendation. As
an enclosed system, if built, it would be adequately installed
in the existing 20' drainage easements with minimal
maintenance needed.
Please note that per the agreement between Skyhawk
Venture/Connell Skaggs Development Co. and the City of
Coppell, dated Dec. 11, 1988, there is a cap on the funds
available in the amount of $345,000.00. Due to trench safety
laws, the cost of such construction has increased. Per the
attached cost estimate for option #1, presently funds in the
amount of $728,000.00 is required to construct this drainage
system. Additionally, please note that as per attached memo
dated 2/14/90, Larry Jackson has indicated that we probably
could require Boorhem & Hinckley to put in a box culvert just
like we required Connell.
Installation of 2- 4' x 12' box culvert and concrete lined
channel, Option #2, is staff's second choice, which may be
considered, but with the estimated total construction cost of
$534,000.00, there would still be a limitation in availability
of funds. At the present only $345,000.00 are available per
agreement.
Please note that staff has the following concerns on this option:
ae
Lack of adequate Drainage Easement (DE) in order to
construct such drainage system, there would be a need for
minimum of 30' D.E..
b. Existing fences would need to be moved back to
accommodate for open drainage channel.
c. Maintenance of such system is of a concern to staff.
Option #3 would be a concrete lined open channel with the cost
estimate of $259,130.00, from Sandy Lake Road to the High
School culvert. Please note that staff would have the same
concerns as listed for option #2; however, the proposed cost
is $85,000 (+) less than the amount agreed upon in the
agreement. Should this option be approved, staff recommends
that the surplus funds ($85,000 +) be escrowed with the City
for future maintenance of the channel and/or purchase of any
related equipment for such maintenance.
Staff along with Connell Development Representative will be
available at the April 24, 1990, City Council meeting to answer any
questions.

Re:
Connell - Skaggs Drainage Improvement
Subject: Shady Dale Lane's Residents
As per your request, we visited with Ms. Pauline Jenkins at 132
Shady Dale on Thursday, April 19, 1990, and did a site
investigation of the above referenced drainage area. Ms. Jenkins
expressed lots of concerns with the existing drainage situation in
her back yard and indicated that she has never had such problem in
the 30 years she has lived in this house until the new shopping
center was put in place (refers to Connell - Skaggs Addition).
Please note that we have also contacted the residents of Shady
Dale, as shown on the attached list, and were able to talk to 6
residents informing them about the reference City Council item...
drainage improvement options.., etc. which will be discussed in the
up coming City Council meeting on April 24, 1990.
Generally the residents are looking for some type of interim
solution to the problem, such as cleaning up the existing ditch,
to avoid drain water from washing up their back-yard, especially in
Ms. Jenkin's case.
Connell - Skaggs representative and engineer will be attending the
April 24, 1990, City Council meeting along with city staff to
answer any questions.
Please let us know if you have any questions.

Lake Road to the southeast corner of Coppell High School
where existing culvert ends.
\ Acting City Engineer Shohre Daneshmand made the presentation to the
\Council. Also present to discuss this item was Mr. Jim Coke
\representing Connell Development. Mr. Coke stated that, since the
\original agreement in 1986, there have been changes in trench
\safety laws which, in effect, drastically change the cost of
\installing a box culvert. Rather than the estimated $345,000 for
~his project, it is anticipated that $728,000 would be required.
however, Mr. Coke indicated that another alternative that would
~eet the trench safety requirements and decrease the cost of the
linstallation of the ~ox culverts to approximately $400,000, is
/through the use of a trench box". Mr. Coke indicated that they
/would be willing to participate up to the $345,000 with the City
/or others providing the remaining funds. The time frame for
/completion of this project would be approximately three months.
/Councilman Robertson provided an additional alternative with the
~/ .... ~ ~ new method called a "blow form" that he felt would also
~ greatly reduce the cost of the installation of the box cu£ver ·
~ citizens present who asked to speak were Mr. L.H. Davis of 100
~ North Shadydale and Ms. Pauline Jenkins of 132 North Shadydale.
I Both citizens expressed their concern with the damage and drainage
I that was coming onto their property. It was also indicated to the
Council that an existing ditch that was present prior to the
I development of the Connell development had been graded over,
thereby preventing proper drainage. Staff was requested to
evaluate this situation. Following further discussion on this
~ item, Councilman Smothermon moved that this item be tabled to the
, May 8, 1990 city Council meeting and that information concerning
fcost of both the "blow form" and the "trench box" methods be
evaluated. Councilman Morton additionally moved that the situation
on the ditch at Shadydale be reviewed by Staff. Councilman Nelson
seconded the motion; motion carried 7-0 with Mayor Pro Tem
Wilkerson and Councilmen Thomas, Morton, Smothermon, Cowman,
Robertson and Nelson voting in favor of the motion.
Item 16. Presentation by Wayne Ginn, Inc. concerning the median
opening just to the north of Grapevine Creek bridge on
Denton Tap Road and speed study for Denton Tap Roads and
South Beltline Road.
Consulting Engineer Wayne Ginn made the presentation to the
Council. Mr. Ginn indicated that his firm had employed the firms
of both Barton-Aschman and DeShazo, Starek & Tang as additional
consultants to study this intersection and have provided the
following recommendations that will enhance the safe operation of
the intersection: 1) remove the metal beam guardrail, 2) pursue
having TU Electric relocate the power pole at the northeast end at
the east bridge, 3) place ,,Intersection Ahead" signs for
southbound traffic prior to the Meadowcreek intersection, 4)
provide striping as recommended by DeShazo, Starek & Tang, 5)
review the parking situation at the medical building on Meadowcreek
and 6) lower the speed limit on Denton Tap Road to 40 miles per
hour. Mr. Ginn indicated that he did feel that the barricades
could be removed at this point and that the speed limit of 45 miles
per hour is a safe speed. Questions raised during discussion on
this item concerned that the consulting engineers look at the
entrance onto Denton Tap from the Goodyear location, that City
Staff conducting a study to consider lowering the speed limit on
Denton Tap and installation of a traffic signal light at the Bethel
School Road and Denton Tap intersections- Following discussion of

at 449 W. Bethel Road.
Chief Building official Dale Jackson made the presentation to the
Council. The requested sign projects three feet from the building
surface as apposed to the allowed 18 inches. Additionally, the
size of the sign is 47.20 square feet versus a maximum of 28 square
feet allowed by the ordinance. Mr. Jay Khorrami of Coppell Deli
and Grocery was present to discuss this item with the Council.
Following discussion, Mayor Pro Tem Wilkerson moved that the
variance request be approved. Councilman Morton seconded the
