I I . Implementing staggered class hours during the 4:00 to 6:00 p.m. time period I and delaying the start times of adult night classes would minimize long queues and corresponding vehicle delay at Lydia Avenue/College entrance in the p.m. I peak hour. IV. STORMWATER MANAGEMENT STUDY I The College's environment is largely a function of its two lakes, Johanna and Little I Johanna, along with ponds and wetlands which occupy a large part of the total land area of the campus. Both lakes are identified as impaired by the Minnesota Pollution Control I Agency (MPCA). Both lakes are also included on the MPCA's March 31, 2004, proposed Total Maximum Daily Load (TMDL) list. The TMDL list serves as a comprehensive source I of streams and lakes that are not meeting their designated uses because of excess pollutants. I Furthermore, Lake Johanna is classified as eutrophic, meaning that is has waters rich in mineral and organic nutrients that promote a proliferation of plant life, especially algae, I which reduces the dissolved oxygen content and often causes the extinction of other organisms. Lake Johanna also exhibits water levels from a high of 881.27 feet on I July 3, 1978, to 870.35 feet on July 21, 1926, or a range of 10.92 feet, and its Ordinary High Water Level is 878 feet. Little Lake Johanna has very little published information. I This Plan presents a campus-wide Stormwater Management strategy that identifies Best Management Practices (BMPs) that can be implemented to facilitate the campus I redevelopment. This Plan's overall goal is to cooperate with appropriate agencies including the Cities of Roseville and Arden Hills, Rice Creek Watershed District (RCWD), and the I Minnesota Pollution Control Agency to improve the quality of both of the campus lakes. Achievement of these goals will deliver good quality stormwater runoff from the campus to I lakes and wetlands at acceptable rates and volumes, while reducing pollutant and sediment loadings, bank erosion, and water quality degradation. I Stormwater quality improvement BMPs that seem particularly appropriate for the campus include: wet detention ponds; pollution prevention such as material storage control, turf I management, parking lot cleaning; pervious pavements to reduce the amount of runoff; infiltration practices and filter devices which primarily trap solids that have pollutants I attached to them.
