RE: PELICAN/BETHELVSCHOOL FOLLOW-UP - PROJECTS AWAITING FUNDING
Attached is a summary list and separate detail lists of public improvement
needs for the City of Coppell. These lists were considered by the City
Council when they approved the funding on December 13, 1988, for the
Bethel School/Pelican drainage study and improvements, and the asphalt
overlays on Bethel Road and Thweatt Road.
The first three items on the Summary Sheet are the totals of the
respective category of needed improvements (i.e. drainage problems,
subgrade failures and asphalt overlays). The last two items are drainage
problems that have come to our attention since December 13, 1988. That is
Hill Drive and North Oak Trail. They are both currently estimated to cost
about $50,000 each, for construction only. Engineering costs'would be
added to that cost.
Additionally, we have other drainage problem areas, such as Lock Lane,
Sandy Lake Road/Leslie, and city wide creek bank erosions that still need
to be addressed.
We will be further compiling these other problem areas, investigating
them, and preparing a strategy to conduct necessary engineering studies,
cost estimates, possible funding alternatives and then execution of the
final engineering and construction of the priority projects that receive
funding.
As can be seen, the total estimated construction costs of these known
projects needing to be done is estimated at $2,303,500.00. When grouped
with the other public improvements in the Five Year Capital Improvement
Plan, and with others that might not yet be identified, we have a good
challenge ahead of us.
Please let me know if you have any questions.

The priority ranking of these drainage problems is purely subjective in that the degree of affect is
based on field experience and judgement. None of these are being presently considered for authorization
with the exception of Pelican.
