Re: Vantage Mini-Warehouse drainage requirements for
Belt Line Road Improvement project
Dear Steve:
As we discussed Gn September 18, 1987, a drainage problem
currently exists on the Belt Line Road project. The problem is
due to the construction of a driveway without a culvert under it
on the east side of Denton Tap Road for the Vantage Mini-
Warehouse Development site.
We have no objections to the driveway itself but have informed
the developer that drainage needs to be maintained along this
section of roadway. This shall facilitate both the construction
and drainage planned under the' scope of the Belt Line Road
project.
Due to our anticipation of the Denton Tap Road project being bid
and construction started within the next 3 - 6 months
approximately, we feel that the drainage can be designed to
accommodate present development and run-off conditions for this
area.
As a result three drainage options were presented to our office
by Mr. Joe Beard (developer) and his engineer Pierce-Lunsford &
Associates. The options discussed were: 1) to place a culvert
under the newly constructed drive; 2) drain the run-off Southward
to a future drop inlet planned for the Belt Line Road project; or
3) drain the,run-off to their drop inlet on 'their South property
line which is east of the roadway.
We agreed that probably the cheapest way to have them go was to
drain the run-off eastward from the road to their on-site drop
inlet. Their engineer verbally assured us that both the fall
eastward to the drop inlet and the 42" RCP pipe out of the inlet
were adequate to accommodate the run-off. Based on their
engineer's recommendation, we agreed to entertain this as a
viable solution to accommodate the temporary drainage until
Denton Tap Road is constructed. It is everyone's understanding
as of September 18, 1987 that if ponding would occur on the east
side of Denton Tap Road, the developer will revise their method
of drainage at that time to insure adequate drainage.

Since this work is temporary in nature, we have waived the
requirements for engineering plans be submitted and approved.
Visual inspection by the City will determine whether drainage is
accommodated.
Due to the developer wanting to secure access to their site this
week, we have agreed to have the Belt Line Road contractor
provide access by removing two concrete traffic barriers in front
of their drive. In return, they have agreed to expedite securing
drainage on the east side of the roadway.
Per our conversation, we understand you will issue a temporary
certificate of occupancy to them after the temporary drainage
improvements are completed. In addition, ail'parties are of the
understandin9 that during the d~sign phase of the private
development, drainage under the drive should have been
accommodated for and this is why this requirement is being placed
on them at this time.
Please call us if you have any question.
Sincerely,
Kevin Peiffer ~ ~
