LRRWMO Meeting Minutes <br />March 15,1989 <br />PAGE 2 <br />OLD BUSINESS AND NEW BUSINESS <br />John Dixon, Barr Engineering, standing in for vacation- <br />ing Dean Skallman, discussed information relative to parking <br />lot sizes and standards as well as a recommended policy for <br />reviewing plats. <br />Dixon stated that there aren't any formal written <br />standards established for determining the need for skimmers <br />and settlement containment for parking lots; however, some <br />form of protection is normally required, depending on the <br />size of the lot. It is preferred that the parking lot <br />drainage be part of a municipal system rather than privately <br />operated in order to more easily see that skimming is <br />actually being done. In answer to Raatikka's query, Dixon <br />recommended that parking lots containing space for at least <br />25 vehicles or more have skimmers. He further reported that <br />other watershed districts have required that industrial <br />developments provide that the entire development has a storm <br />drainage system for the area within the plat being <br />developed. The intent is that storm sewers meet the state <br />of- the -art design to improve water quality for storm water <br />discharge. <br />The board reviewed the Water Management Plan language <br />relating to storm water or surface runoff. The extent of <br />this board's review of plats developed to ensure proper storm <br />water discharge was discussed. <br />Dixon stated that with this board's review of plats, a <br />uniformity will be achieved. It was his suggestion that this <br />organization establish a policy and in some way see that it <br />is enforced. Watersheds he has been involved with have <br />reportedly gone to a permit system relating to sedimentation <br />and erosion control. Dixon stated that cooperation between <br />watershed districts and municipalities is extremely <br />important. <br />Dixon went on to report that recent legislation states <br />that the DNR will be looking at one -acre wetlands to fall <br />under their jurisdiction throughout the State. Should <br />permits be required, they will want to come to this WMO as <br />well as cities for review on the permits. This body should <br />be involved in the non -point discharge that is four to five <br />years away. By 1992 or 1993, storm sewage will have to be <br />permitted, creating a concern for the water quality coming <br />from these storm sewers. <br />
