Dear Mr. Bentley:
I have received and reviewed the revised drainage layout for the proposed Grandy's site on
Denton Tap Road. While the layout does vary somewhat from what we discussed on August 22,
2002, conceptually it does appear that it will still work as presented.
I have reviewed the Denton Tap Road construction plans and the Denton Tap Road Development
(i.e., Everybody Fits) construction plans to make my final decision. In the Denton Tap Road
construction plans, they show approximately .8 acres draining to the inlet which you are now
proposing to tie into. That .8 acres was suppose to come from the Taco Bell site; however, Taco
Bell took the majority of their drainage down the road that leads to Everybody Fits. Only
approximately .2 acres drain to this inlet presently. You are proposing approximately .6 acres to
go to this inlet; therefore, that equates back to the original design capacity of this area, which is
approximately .8 acres.
The fill along the north side is slightly greater than we discussed; however, given the
circumstances will be acceptable. My understanding of the drainage plan as submitted, is that
you will take Drainage Area A, approximately 5 cfs, to an on -site inlet d drain it
cf to
existing inlet in Denton Tap Road. You will allow Drainage Area B, approximately 25
drain overland to the existing access easement to the north. You will allow Drainage Area C,
approximately 4.0 cfs, to drain overland to the west.
The City will work with you expeditiously to review your plans to allow for rapid construction of
this site. Final construction plans submitted that reflect the drainage as provided to me on
August 23, 2002 will be acceptable. If you have any questions, please contact this office at your
convenience.
