Re: Drainage Letter
Taco Bell (SP) — 1 1- 005001 43
To Whom It May Concern:
The Taco Bell site is located on Lot 18, Block 3 of the Tower Point Subdivision Phase 8A. This project is
proposing to construct 2,949 SF building with associated utilities and parking. The proposed
impervious cover for the Taco Bell is 29, 457sf (0.67 acres). Using the time of concentration = 10
minutes and runoff coefficient = 0.9 per Stromwater Drainage Report for Tower Point Infrastructure
Development for Private Drive G & H. The stormwater flow from the Taco Bell site is 5.20 cfs. The taco
bell site will sheet flow most of the stormwater runoff to the northwest area of the site and drains to a
proposed 3'x3' area inlet. The area inlet will connect to the existing junction box #20 per Stromwater
Drainage Report for Tower Point Infrastructure Development for Private Drive G & H, via proposed 18"
RCP stormwater pipe. See sheet C41 for location of proposed area inlet and storm pipe.
The stormwater flow from the Taco Bell site is in line with assumptions made on the drainage report for
Tower Point Infrastructure Development for Private Drive G & H, dated September 7, 2010, prepared by
Walter P. Moore and Associates.
I hope that you find this information adequate. Should you need anything further, please contact me at
