RE: Take 5 Quick Lube 9799 Michigan Road FES Project # 1904001
Dear Mr. Cashman,
Please accept this letter related to the Take 5 Quick Lube project as support of the following technical variance
requests. 1. A variance to permit the proposed new drive cut as configured. Specifically, to permit the use of 20’ curb radii into the site rather than the standard Carmel commercial drive entrance of 30’ radii. The
proposed use will not require large trucks to access the site. The majority of traffic will be customers in passenger vehicles with the occasional box truck for delivery and pickups. Due to the limited depth of
the project site there are also physical difficulties with providing a larger radius on the entrance drive while maintaining the proper vehicular movements within.
2. A variance to allow for the stormwater management system as designed to restrict outflows from the
detention/infiltration basin to the downstream receiving regulated drain in excess of the 0.1 cfs/acre for the 2-10 year rainfall events. Due to the small contributing drainage area of 0.54 acres including the
onsite and ½ Right of Way, the allowable and proposed discharge rates are as follows:
Please review the above requests and let me know if any additional information is required to complete your review and recommendation to the BPWS for approval.
