RE:
Alan D. Ratliff, City Manager
Russell R. Doy ., City Engineer
CAPITAL PROJECTSWHICH MAY BE FUNDED PROM BALANCE
OF CAPITAL FUNDS (CONTINUED ITEM FROM DECEMBER
15, 1989 CITY COUNCIL AGENDA)
On December 15, 1988, the City Council approved the first three of the
four projects recommended by staff per the December 8, 1988, Doyle/Goram
memo(copy attached).
The 4th Project recommended, placing a 2 inch overlay on Southwestern
Boulevard from the Denton Tap Road Connection to Coppell Road, was not
approved and the City Council directed staff to see when the Prospective
owners of Gateway Park were going to improve Southeastern Boulevard as
previously committed is during the approval of the Final Plat for the
Gateway Park addition.
Since then Prentiss Copley Investment Group has purchased Gateway Park,
but still has not yet determined their approach to build Gateway Park.
Initially, they were going to start on the southerly part of a tract where
there is existing infractructure. Their Consultants have inquired about
possible movement of the alignment of Gateway Boulevard. They still do
not have any definite plan as yet.
Additionally, since (and in response to) the approval the Pelican Bethel
School drainage study we have become aware of the inadequate drainage of
the alley behind 141 Hill Drive where Mr. Gary Hamrick resides. (We had
previously known of over land flooding, but not structural/house flooding).
In the attached January 10, 1987 memorandum, staff summarized the
circumstances in the alley behind 141 Hill Drive after Steve Goram and
met with Mr. Hamrick on site. In response to a subsequent meeting with
you and Steve Goram, the resident at 145 Hill Drive was contacted and we
found out that indeed the house at 145 Hill Drive was flooded throughout
on July 12, 1988 causing $900.00 damage. The July 12, 1988, storm caueed
the flooding in the houses at Pelican and Bethel School Roads.
Additionally, Mr. Hamrick told us that a number of his neighbors have
speed bumps placed just inside their garage doors to keep storm water from
entering their garages. Therefore, we sought to retain professional
engineering services to investigate the situation and develop a proposal
for resolving this drainage problem. Since there was damage to
property/structural flooding, per our criteria, this flooding sit~a~ion
becomes a priority right after the Pelican/Bethel School flooding in front
of the resurfacing items.
Therefore, it is recommended the $44,500.00 previously recommended for the
resurfacing of Southwestern Boulevard, be allocated for the professional
services needed to study the situation in the alley behind 141 Hill Drive
and the engineering design and construction remodeling the alleyway and
storm water collection systmm to better handle the storm water.
The attached letter and proposal was solicited from DeShazo, Starek and
Tang, the City of Coppell's design engineers, for the Bethel Road Drainage
Project (Minyard). Since staff has developed a confortable confident
rapport with this firm and their drainage engineers and since it is
advisable to diversify our sources for professional services (i.e., not
keep all our eggs in one basket), we requested the attached proposal.
As can be seen, the experienced consultant engineer selected here has by
letter and proposal already identified the situation and possibile
solution. Therefore, we request that the $44,500 originally recommended
for Southwestern Boulevard overlay be allocated toward the preliminary
engineering evaluation Phase A on the attached proposal not to exceed
$5,800.00 and the construction of recommended improvements to the drainage
in the alley. When Phase A is executed and the report received, we will
return to the City Council with the estimated cost for the construction of
improvements recommended to improve the drainage in this alley behind 141
and 145 Hill Drive including the design engineering required to complete
the final engineering plans ready for bidding.
At that time, we will ask the City Council to approve the funding for and
execution of a professional services contract for the design and
preparation of the final engineering drawings. As indicated on the
attached letter, it is estimated that final engineering plans and
construction expenses could likely range in cost from $40,000 to
$55,000. If we hit the lower part of the range we will not need any
additional funding beyond the $44,500. If not, we will need to find and
then request aditional funding before we either execute the professional
services contact for the final plans and/or when we seek City Council
approval to award the contract to the lowest qualified bidder.
I hope this preparation for resolving this drainage problem in the City of
Coppell is acceptable and if there are any questions, please advise.
