CASE #2 Consider Storm Sewer and Utility Improvements Projects Background: A review of this winter's conditions and complaints has identified two candidate storm water projects for consideration this construction season. The first project would be a drainage improvement at the intersection of Alpine Drive and Waco Street. At this location Waco Street, ~vhich has a poorly developed rural ditch section for drainage, meets Alpine Drive, which has concrete curb and gutter. There is currently a catch basin, which is located in the north curb line of Alpine Drive just east of this intersection. This condition could.be eliminated by the installation of catch basins on the southeast and southwest corners of this intersection, which could be made to drain into the existing catch basin in the north curb line. The estimated cost of this work is approximately $14,000, which would include the complete replacement of 100 feet of badly deteriorated pavement on Waco Street just south of this intersection. The second candidate project is a result of a complaint by Mrs. Barb Beabeau who resides at 6376 143rd Lane (the southeast corner of Sunfish Lake Blvd and 143rd Lane). A small drainage area northeast of Mrs. Beabeau's property drains into a rural ditch section adjacent to 143rd Lane. This ditch system is directed through a culvert to the south side of. the roadway and the natural grade transmits drainage into Mrs. Beabeau's property. There is no drainage and utility easement over this portion of her lot. In addition, Mrs. Beabeau has a wooden retaining wall in the vicinity and is concerned about the impact of the drainage on this wall. This flow ultimately ponds in her back yard. It is proposed that the storm water be redirected westward along 143rd Lane to Sunfish Lake Boulevard and then southward for a distance of approximately 230 feet to an existing storm sewer which discharges westward across Sunfish Lake Boulevard into a lot, which is presently owned by the City. Water drains from this location overland into the wetland 657 W. The estimated cost of this project is $20,000. The third project is proposed to be fixed through Tax Increment Financing. This project is related to the need to reroute a storm sewer constructed by Waste Management, which is currently owned by Minnesota Pollution Control Agency. It is located across Lot 1, Block 2 Sunfish Lake Business Park. This storm sewer is currently used on occasion by MPCA to augment the groundwater treatment system that relies primarily on ponds. The existing storm sewer runs diagonally across the property, which limits the development pot'~ntial. It is proposed that this storm sewer be realigned. The cost of this work, including the removal of the existing sewer is estimated to be approximately $50,000. It is proposed that funds for this project would come from TIF funds. Motion to recommend that the City Council direct that plans and specifications be ordered for the projects outlined above as the 2005 Storm Sewer Improvement Project. Action: Ratify the recommendation of the Public Works Committee. -356-
