DRAINAGE PROBLEM IN MENKVELD'S COUNTRY PARK By: Pete Raatikka, city Engineer CASE Background: Over the past several years with increased development in the area, the ponding area on Lot 3, Block 4 in Menkveld's Country Park has proven to be inadequate during periods of heavy rainfall or rapid spring thaw. On the weekend of March 10 and 11, 1990, a combination of rapid spring thaw and heavy rainfall again caused flooding of Lots 2 and 3, Block 4, Menkveld's Country Park beyond' the limits of the easement. As a result, I have received calls from the owner of Lot 3, Block 4 and a letter from Mr. Karl J. Yeager, attorney for the owner of Lot 2, Block 4, questioning what measures will be taken by the City to prevent future damages from the continuing drainage problem. During the fall of 1988, the city was proposing to increase the volume of the ponding area by excavating it deeper and increase the percolation rate by removing the impervious materials and replacing them with pervious materials. The owners of Lot 3, Block 4, Mr. and Mrs. Joe Kerkiede objected to the excavation of the easement area due to potential safety hazards and appeared before City Council on November 15, 1988. City Council directed the public works superintendent and myself to meet with the Kerkiede's and work out a solution acceptable to the Kerkiede's. During the summer of 1989, the City's street department replaced some of the impervious materials within the easement with pervious materials to increase the percolation rate. However, due to the mild winter with periods of freezing and thawing, the easement area was substantially frozen to restrict percolation of runoff from the March 10 and 11 rainfall. This situation was common in other areas of the City which had dry wells or ponding areas and also in numerous other communities. To alleviate the drainage problem, the ultimate solution is the installation of storm sewer to this area. Based on the City's Comprehensive Drainage Plan, this area should drain south to County Ditch No. 66. I have estimated the cost of such improvement to be in the magnitude of $60,000. It is proposed that such an improvement would be financed by the Rum River Storm Sewer Taxing District in accordance with City Resolution 87-90. The first step in initiating such a project would be to order a feasibility study.
