City Council Marshan Lake Industrial Park September 22, 2003 along Lake Drive as well as additional right -of -way for sight corners at the intersection. The street is proposed to be constructed to a 38 foot width which is adequate to service industrial traffic. Access control, dedicated to Anoka County, should be shown on the plat on Lots 1 and 4 adjacent to Lake Drive. Grading and Drainage. A grading and drainage plan has been submitted for review by the City. The existing drainage flows north to Anoka County Ditch No. 10, which runs along the northern property line of the proposed plat. An existing private drainage ditch runs northerly through the property into the County Ditch Ten. The private ditch will be diverted into a proposed storm sewer to accommodate site drainage. The new storm sewer will be routed through on -site infiltration basins and /or holding ponds and ultimately into County Ditch Ten. The County ditch will be preserved in its existing condition. The City Engineer has completed a review of the Grading and Drainage Plan. His comments, dated September 18, 2003, are attached. The proposed project is in general conformance with City requirements Utilities. The subdivision is proposed to be serviced with public sanitary sewer and water utilities. The sanitary sewer service will be provided by the existing trunk sanitary sewer main that runs along the west side of the site, parallel to I- 35W. The sanitary sewer laterals will be extended through the site and out to Lake Drive. A twelve -inch water main is proposed to be extended from the existing trunk water main along 135W to Lake Drive. Staff originally recommended extending the sanitary sewer to the north property line along Lake Drive and the Water Main to both the north and south property lines. However, upon further review of the City's Sanitary Sewer and Water Comprehensive Plans staff is recommending that the lines only be extended to Lake Drive. Both trunk sanitary sewer and water main lines are set up to be extended on the east side of Lake Drive. Trunk utilities both north and south of the sight would be extended in conjunction with either future development and /or a City Trunk Utility project. Properties on the west side of Lake Drive would be serviced from the trunk lines by individual service connections. Extension of utility laterals would result in duplicate systems and ultimately in higher infrastructure costs. The City Engineer has completed a review of the Utility Plan. His comments, dated September 18, 2003, are attached. 4
