All hardcover will be gravel. No solid concrete pads or impervious liners will be installed. <br /> For the sake of calculations I've included both stockpiles as depicted in the sketch, although in reality these <br /> will be quite variable and will fluctuate as raw materials are processed and reused on the County Road 112 <br /> project. I have also calculated the entire area between the stockpiles and the stabilization pad as vehicles will <br /> be driving in and out of that area. <br /> The total maximum hardcover for the area of activity is just over 2.0 acres. (-25%of the area of activity, or <br /> .07%of the site) <br /> • The 24" wide gravel access road =984 sf <br /> • Raw materials stockpile = 10,000 sf <br /> • Finished material stockpile = 15,00 sf <br /> • Stabilization pad =27,000 sf <br /> • Traffic pattern area= 37,500 sf <br /> Thanks so much for following up. We are going before the Orono Planning Commission next week, so it would <br /> be helpful to have either a permit or a letter stating that no permit is necessary by the end of the week. <br /> Dana <br /> LAKE VATT <br /> inliartalit L11 <br /> Nana S.Brumitt I Communications <br /> +1.952.653.1359 <br /> dana@Iwestdev.ccr <br /> From:Jack Distel<Jdistel@minnehahacreek.o, > <br /> Sent: Friday, March 10,2017 11:21 AM <br /> To:Dana S. Brumitt <br /> Subject:MCWD recycling center at 3245 Wayzata Boulevard West <br /> Dana, <br /> After carefully looking over the plans for the recycling center at 3245 Wayzata Boulevard West in Orono we have come <br /> to understand more clearly what the watershed district needs. As the site is a temporary installation it quite unique but <br /> our main concern is the storm water potential of the site and how this could impact the surrounding wetlands. Would <br /> you be able to calculate the amount of impervious surface on the site and what percentage this is compared with the <br /> site in total? MCWD considers compacted gravel surfaces as impervious,therefore we are looking for this calculation to <br /> include the area of things like: <br /> 1. The access road <br /> 2. The stabilization pad <br /> 3. The stock piles <br /> 4. Any other impervious surface to be installed on site. <br /> 3 <br />
