CASE # <br /> <br />CONSIDER STORM SEWER UTILITY IMPROVEMENT PROJECTS <br /> By: Steven J. Jankowski, City Engineer <br /> <br />Background: <br /> <br />Late winter and early spring are periods when drainage needs often become readily <br />apparent, particularly in Ramsey were sand soils readily drain in nonfreezing weather. A <br />review of this winter's conditions and complaints has identified two candidate storm <br />water projects for consideration this construction season.. In addition, a third storm water <br />project needs to be considered to make economic use ora property the City has acquired <br />for development purposes. <br /> <br />Project No7. The first project would be a drainage improvement at the intersection of ' <br />Alpine Drive and Waco Street. At this location Waco Street which has a poorly <br />developed rural ditch section for drainage meets Alpine Drive which has concrete curb <br />and gutter. The attached photos Which were taken this winter illustrates the problem, the <br />entire width of Waco Street south of the intersection is ice covered for weeks. There is <br />currently a catch basin which is located in the north curb line of Alpine Drive just east of <br />this intersection. This condition could be eliminated by the installation of catch basins on <br />the southeast and southwest comers 0fthis intersection which could be made to drain into <br />the existing,catch basin in the north curb line. The estimated cost of this work is <br />approximately $14,000 which would include the complete replacement of 100 feet of <br />badly deteriorated pavement on Waco Street just south of this intersection. <br /> <br />Project No2. The second candidate project is a result ora C6mplaint by Mrs. Barb. <br />Beabeau who resides at 6376 143ra Lane (the south east comer of Sunfish Lake Blvd and <br />143r'~ Lane). Attached is a sketch which shows that a small drainage area north east of <br />Mrs. Beabeau's Property drains into a rural ditch section adjacent to 143rd Lane. This <br />ditch system is directed through' a culvert .to: the south side of the roadway and the natural <br />grade transmits drainage into Mrs. Beabeau's property. There is no drainage and utility <br />easement over this portion of her lot. In addition, Mrs. Beabeau has a wooden retaining <br />wall in the vicinity and is concerned about the impact of the drainage on this wail. This <br />flow ultimately ponds in her back yard. It is proposed that the storm water be redirected <br />westward along 143~d Lane to Sunfish Lake Boulevard and then sOUthward for a distance <br />of approximately 230 feet to an existing storm sewer which discharges westward across <br />Sunfish Lake Boulevard into a lot which is presently owned by the City. Water drains <br />from this location overland into the wetland 657 W. The estimated cost of this .project is <br />$20,000. <br /> <br />?roject No3. The third project is related to t.he need to reroute a storm sewer constructed <br />by Waste Management (now owned by Minnesota Pollution Control Agency) across Lot <br />1, Block 2 Sunfish Lake Business P'ark in the early 1990's to transmit treated.. <br />~oundwater to the Mississippi River. This storm sewer is currently used on occasion by <br />MPCA to augment the groundwater treatment system which relies primarily on ponds: <br /> <br />· . _365_3 <br /> <br /> <br />
