m sedimentation of these slopes during and after construction. Once construction is completed in these areas, permanenf erosion control measures will be implemented in accordance with permit requirements." Since the project will displace more than one acre of land, application for coverage under the NPDES Permit will be submitted to the MPCA prior to starting earthwork on fhe site. The contract documents for the project wil! require the Contractor to install and maintain BMPs (Best Management Practices) until fina! restoration of the project is complete and the Notice of Termination had been filed wiih the MPCA. During construction, the Contractor is expected to use temporary erosion control devices such as tree protection fence, perimeter silt fence, rock construction entrances, construction phasing and timely stabilization of disturbed surfaces. The MPCA, the Rice Creek Watershed District, and the respective City will have final approval of all details pertaining to erosion control procedures. Because the project will be monitored to assure compliance with the NPDES Permit through the entire construction process, `adverse effects,from erosion and sedimentation ,�s :;�, should be minimized. ��, �' � " Department of Natural Resources (DNR) A.

Comment: The 125-stall parking lot west of the Fine Arts Center is in an area where the topographic features appear to meet the definition of a steep slope or bluff area, and as indicated by the soils survey. Additionally, the site drains toward Little Lake Johanna and the proposed construction will require substantial tree removal. We strongly recommend that the College consider an alternative site or layout. Response: See response to Question 1.8.6. above. In addition, the Co/lege recognizes the sensrtivity of this bluff area, especially in relation to the exisfence of trees and the narrowness of the buildable area. In response to this comment, the College is prepared to remove this parking lot feature from fhe Master Plan. TKDA Project No. 13529.002 Page 9 Draft Date: July 9, 2007
