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 MST <br />OEVELIPMENT, LIC <br />7' <br />D2na 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 />I. The access road <br />2. The stabilization pad <br />3. The stockpiles <br />4. Any other impervious surface to be installed on site. <br />
