If yes, identify water resource affected and give the DNR Protected Waters Inventory number(s) if the <br />water resources affected are on the PWI: 62-58 (Little Lake Johanna) and 62-78 (Lake Johanna). <br />Describe altematives considered and proposed mitigation measures to minimize impacts. <br />There will be some physical alteration of several outfall structures located arotend Lake Johanna and <br />one located by Little Lake Johanna. These outfall structures are in need of rehabilitation or <br />replacement and these irnp�-ovements will coincide with other stormwater management improvements <br />and portions of the proposed project, depending on the location of the outfall structure. For example, <br />out.fa/I structures locuted near the proposed relocation o.f the loop road will be modified and improved <br />as this portion of lhe project proceeds. <br />Special measures will be taken to protect any adjacent water bodies or wetlands_from erosion and <br />sedimentation during and after construction while vegetation is getting established. Installation of high <br />flow silt fences and bio-rolls will be installed prior to construction and maintained throughout <br />construction until turf has been established. <br />A NPDES permit (as requrred by the MPCA) and a Rice Creek Watershed District permit, in <br />accordance with all Rules and Regulations, will be obtained prior to construction. As part of the <br />NPDES per-mit, temporary and permanent erosion and sediment control plans will be prepared for <br />approval. In addition, Storm Water Pollution Prevention Plans will be submitted by the Contractor for <br />approval. All approved plans will be implemented prior to commencement of constrzrction and wrll be <br />maintained until al/ construction has been completed and turjhas been established. The plans will <br />address vehicle tracking of sediment, inspection of erosion control measures, and time frames in which <br />the erosion control measures will be implemented. <br />13. Water use. Will the project involve installation or abandonment of any water wells, connection to or <br />changes in any public water supply or appropriation of any ground or surface water (including <br />dewatering)? X Yes No <br />If yes, as applicable, give location and purpose of any new wells; public supply affected, changes to be <br />made, and water quantities to be used; the source, duration, quantity and purpose of any <br />appropriations; and unique well numbers and DNR appropriation permit numbers, if known. Identify <br />any existing and new wells on the site map. If there are no wells known on site, explain methodology <br />used to determine. <br />The project will not involve the installation or abandonment of any water wells or the appropriatiorz of <br />any ground or surface water. <br />The project may involve additional connections to service the proposed additional burldings. Based on <br />water usage data from 2005 and 2006, the average monthly water usage is approximately 2, 032, 312 <br />gallons. This assumes that 24, 387, 745 gallons serves 1, 600 FTE students and the associated staff and <br />faculty on campus on an average annual basis. With an increase in student population to a total of <br />2, 400 FTE students along with the associated faculty and staff, the average monthly water usage is <br />�xpected to increase to an approxtmate 3,048,468 ga[lons. This then assumes that 36,581,618 gallons <br />will serve the 2,400 FTE students along with the associated faculty and staff on an average annual <br />basis. This is an approximate increase in water usage oj33%. The source of that water will be from <br />the cities ofArden Kills and Rosevi/le. The increases are approximated to be evenly distributed <br />betweerr the rivo citres based on the current proportion of water usage from each city. <br />14. Water-related land use management district. Does any part of the project involve a shoreland <br />zoning district, a delineated 100-year flood plain, or a state or federally designated wild or scenic river <br />land use district? X Yes No <br />If yes, identify the district and discuss project compatibility with district land use resMctions. <br />a�,ge 6 <br />
