Northwestern College Master Plan <br />Roseville, Minnesota <br />Supplement <br />Findings of Fact <br />Conclusions of Law <br />And Order <br />17. Expansion of the College will result in an increase in water consumption over the course <br />of the project. The City of Roseville and the City of Arden Hills will each absorb half the <br />increased demand and can do so without risk of significant environmental impact. No <br />evidence presented during the EAW process indicated that either City's municipal water <br />system was inadequate to meet water consumption demands. <br />18. The project would not involve changes in water surface usage, and therefore does not <br />create a risk of signiticant environmental effects on water surface usage. <br />l 9. Several coinmenting pariies in the EAW process asserted that construction of a proposed <br />parking lot near Little Lake Johanna would present sedimentation, erosion, and water <br />quality problems. In response to public comments, the applicant has agreed not to <br />include the proposed parking lot near Little Lake Johanna in its expansion plans. <br />Remaining potential impacts due to soil removal can be mitigated by temporary and <br />permanent erosion control measures and best management practices. MPCA oversight <br />under the NPDES permit, as well as oversight by RCWD, the City of Roseville, and the <br />City of Arden Hills, will also mitigate potential impacts from erosion and sedimentation. <br />20. Impervious surface at the project site will increase as a result of the project. The increase <br />in surface water runoff will not create the potential for significant environmental lake <br />impacts that are reasonably expected to occur. Potential surface water impacts to the <br />lakes can be mitigated through Best Management Practices identified in the Stormwater <br />Management Plan including: wet detention ponds; pollution prevention such as material <br />storage control, turf management, parking lot cleaning; pervious pavements to reduce the <br />amount of runoff; infiltration practices and filter devices which preliminarily trap solids <br />that have pollutants attached to them. These requirements will be imposed as part of the <br />approval process for the project. Pertinent requirements of the City, MPCA, and RCWD <br />require that water runoff rates and volumes be equal to or less that pre-project rates and <br />volumes. <br />21. Expansion of the College will result in increased sewer usage on campus over the course <br />of the project. The City of Roseville and the City of Arden Hills will each absorb half of <br />the increased waste water and each will send the wastewater to the Metropolitan <br />Wastewater Treatment Plant, which has adequate capacity to treat the additional <br />wastewater without risk of significant environmental impact. <br />22. The project may have a minimal impact on soil conditions, but will not create the <br />potential for significant environmental impacts on soil conditions that are reasonably <br />expected to occur. Potential impacts on soil conditions will be mitigated through Best <br />Management Practices to ensure that site runoff and siltation are minimal or prevented. <br />-4- <br />
