Drainage Plans of Coppell High School
As you know, the Preliminary Plat of the above project was approved ou
January 13, 1987. The Final Plat has not been submitted yet; however, I
received two (2) sets of Drainage Plans on Public Storm Drain (proposed
box culvert, line A, proposed 60" RCP to the north of the property and
48" RCP - 54" RCP connected to the box culvert) which would be within
the drainage easement. To expedite their project, I reviewed and
commented on the Drainage Plans. Mr. Gabe Favre with Ginn, Inc. had
forwarded his review and comments on the Drainage Plans to me (he had
also received 2 sets of plans from the Engineer).
John Nall and Tom Rutledge with Teague Nall and Perkins came by on
Friday, February 20, 1987 at 4:30 p.m. to pick up the mark-up plans.
They asked me to go over the plans with them and I did so. I mentioned
to Tom that as a normal procedure, there should be a final plat
submittal, including the Final Plat, Site Plan, Landscape Plan,
Irrigation Plan, Street Lighting Plan and Final Engineering Construction
Plans; for the Development Review Committee to review and make
recommendations to the Planning and Zoning Commission and the City
Council.
Tom's response to one of my comments is the reason for this memo; to ask
for your supervision. The Drainage Plans showed two (2) sets of Storm
Drain Systems, clearly marked "PUBLIC" and "PRIVATE", and details
provided on the plans were only for "PUBLIC STORM DRAIN". This property
is a 50 ~ acre tract and most of the water shed is taken care of by the
on-site storm systems (referred to as "PRIVATE" on the plans) and
eventually the water is drained to Cottonwood Creek, along the north
side of said property.
I asked Tom if there are any plans and profiles of the "PRIVATE STORM
DRAIN" and he commented: "We don't see why we should submit any plans
on private lines to the City." He added: "Mr. Wayne Ginn did not have
any problem with it when we talked to him. We are presently taking bids
on this project (no specifics) and instead of Reinforced Concrete Pipe
(RCP) we are using PVC."
Frank, we, City Staff, are in need of your supervision on such an
important step of land development. As you know, administrating
Floodplain Management has always been an important task handled by the
City, and Staff should review Private or Public Storm Systems for the
welfare of the Citizens of Coppell. Based on what I learned from the
former City Engineer, Mr. Ed Powell, "PRIVATE SYSTEMS" are privately
maintained utility systems, but designed and inspected per the City of
Coppell's Standard Construction Details.
My understanding is that Teague Nall and Perkins Engineering has no
intention of getting the City's blessing on Private Storm Systems and as
a concerned City Staff, I am informing you of this situation. Please
advise.
Thanks.
