RE: Advantage Self-Storage - Final Plat
Dear Mr. Pierce:
As you know, we have had several meetings since January 5, 1987,
concerning the above project. This project has progressed greatly, and
DRC comments have mostly been responded to prior to the Planning and
Zoning meeting, except drainage design (use of 100 year storm instead of
5 year storm). This matter has been City Staff's concern from the first
day and I made a comment in this regard at the Planning and Zoning
meeting of January 15, 1987; that 100 year storm design has been a
standard practice in the City of Coppell and should be used. I did also
mention that we (City Staff) would work with the Engineer and Developer
to come up with a functional storm system and inlets to avoid any
drainage problem on the south adjacent property.
During this process, Mr. Wayne Ginn was chosen as a Temporary City
Engineer by the City Council on January 13, 1987; and if you recall, Mr.
Gabe Favre of Ginn, Inc. and I, met with you and Mr. Joe Beard (the
owner) to discuss Drainage Design Frequency in detail (meeting on
January 26, 1987). I asked you to submit the revised construction plans
in a few days no later than Thursday, January 29, 1987. I did not
receive the plans until Monday, February 2, 1987 at 3:30 p.m.; and with
the short period of time given to me, I reviewed your construction plans
and listed below are my comments:
1) The storm sewer pipe has been changed from 33" RCP to 42" RCP and
is adequate for drainage of 100 year storm.
2) Provide a Hold Harmless Agreement releasing the City of Coppell of
liabilities arising from any flooding on the adjacent south
property, that may be caused by drainage.
3) The Fire Lanes shall be 6" thick, 3000 PSI reinforced concrete
instead of 5" (Refer to Paving Plan, General Notes, Item 2).
4) As previously mentioned, the Utility Easement should be outside of
the fence for the water meter box in the northwest area of the
site.
5) Is the length of the 18" RCP (Line B) 45 L.F. or 35 L.F.? Please
specify.
6) The entrance driveway is too steep.
7) Delineate Revision Dates on the construction plans.
8) The final construction plans should have a cover sheet, the
utilitiy plans and standard construction details of the City of
Coppell.
Please contact me if you have any questions.
Sincerely,
Shohre Daneshm~- - ~'~
