RE: Drainage for Lot 3, Market Place P.U.D.
Italian Oven Site
Our Project Number: 92.16 GHA
Dear Glen:
I would like to review with you the site drainage for Lot 3 of the Market Place P.U.D.
This lot is being developed as a restaurant site at the northwest corner of the Market Place
Development. As you indicated at conceptual review, the drainage from this area was
provided for as part of the Market Place P.U.D. Development, and a formal drainage report
would not be needed.
We have therefore designed the Lot 3 site improvements to comply with the
requirements outlined in the Market Place Drainage Report as follows:
1. All runoff from Lot 3 is directed to the existing inlet and detention pond.

2. Our calculations, based on field survey, show that 11,391 cubic feet of volume
exists in this pond. Approximately 10,950 cubic feet of volume was to be
provided based on the Market Place Drainage Report. The orifice plate at inlet
A-1 has a 2" x 2" opening and will control runoff from Basin A-1 at the
approved rate of 0.25 cfs.
Since all of the adjacent improvements are in place, only the building improvements,
curb adjacent to the building and a small area of parking need to be constructed. Since no
overlot grading will be required and since no water flows away form this site, we have not
included any erosion control measures.
I hope this answers any questions you may have concerning this project and please feel
free to contact me should you have any questions.
Sincerely
