<br />. Diverting p.m. peak campus vehicle trips to and from the west via the west gate <br />would greatly reduce vehicle delay at Lydia Avenue/College entrance. <br /> <br />. Implementing staggered class hours during the 4:00 to 6:00 p.m. time period <br />and delaying the start times of adult night classes would minimize long queues <br />and corresponding vehicle delay at Lydia Avenue/College entrance in the p.m. <br />peak hour. <br /> <br />IV. STORMWATER MANAGEMENT STUDY <br /> <br />The College's environment is largely a function of its two lakes, Johanna and Little <br />Johanna, along with ponds and wetlands which occupy a large part of the total land area of <br />the campus. Both lakes are identified as impaired by the Minnesota Pollution Control <br />Agency (MPCA). Both lakes are also included on the MPCA's March 31, 2004. proposed <br />Total Maximum Daily Load (TMDL) list. The TMDL list serves as a comprehensive source <br />of streams and lakes that are not meeting their designated uses because of excess <br />pollutants. <br /> <br />Furthermore, Lake Johanna is classified as eutrophic, meaning that is has waters rich in <br />mineral and organic nutrients that promote a proliferation of plant life, especially algae, <br />which reduces the dissolved oxygen content and often causes the extinction of other <br />organisms. Lake Johanna also exhibits water levels from a high of 881.27 feet on <br />July 3, 1978, to 870.35 feet on July 21, 1926, or a range of 10,92 feet, and its Ordinary <br />High Water Level is 878 feet. Little Lake Johanna has very little published information, <br /> <br />This Plan presents a campus-wide Stormwater Management strategy that identifies Best <br />Management Practices (BMPs) that can be implemented to facilitate the campus <br />redevelopment. This Plan's overall goal is to cooperate with appropriate agencies including <br />the Cities of Roseville and Arden Hills, Rice Creek Watershed District (RCWD), and the <br />Minnesota Pollution Control Agency to improve the quality of both of the campus lakes. <br />Achievement of these goals will deliver good quality stormwater runoff from the campus to <br />lakes and wetlands at acceptable rates and volumes, while reducing pollutant and <br />sediment loadings, bank erosion, and water quality degradation. <br /> <br />Stormwater quality improvement BMPs that seem particularly appropriate for the campus <br />include: wet detention ponds; pollution prevention such as material storage control, turf <br /> <br />Northwestern College Master Plan <br />PUD Application Report <br /> <br />10 <br /> <br />13529.000 <br />
