Re: Kemper Residence response to Storm Comment #3a
IECO No. 15-0736
Dear Jennifer,
This letter is in response to your storm comment #3a regarding the existing detention system
installed per the Plat (S98-082). The detention system was designed to accommodate 5,000 sqft
of impervious surface for the proposed development.
A site reconnaissance was performed to verify the functioning of the detention system on
December 16th 2015. Based on the visual inspection, it is my opinion that the detention system is
functioning properly and can accommodate the drainage from the proposed project as designed.
Also, the downstream of the system does not appear to have any drainage constraints.
Sincerely,
Brian R. Kalab, P.E.
