City Council Regular Meeting Minutes • June 23, 1998 Page 13 1 Mr. Willenbring displayed a picture of Monroe Park which is located in the City of Richfield. 2 This is a sandy environment which is utilizing french drains rather than a gravity system. This 3 park area was lowered by six feet. The City of Richfield was developed in the same era as St. 4 Anthony and is currently using all their parks to hold rain water. 5 Mr. Jedinak expressed concern that when the whole basin fills with water,the pressure will be so 6 great that it will open the veins and bring water into his basement. He asked how large the buffer 7 area would be. He noted that the park will lose approximately one acre of land with this proposal 8 and questioned how all the amenities would be placed on only three acres. 9 Mr. Willenbring again explained that the depression should lower the water table in the area. He 10 stated that the buffer zone will be fifty to sixty feet. He acknowledged that the size of the park 11 will be reduced by approximately one acre. 12 Cindy Lerner Smith, 3100 29`'Avenue NE, noted that ground water is a problem for her. Her 13 sump pump runs constantly. She has an eleven month old child and is concerned with the safety 14 of children around the depression. She asked if there was something that could be done to 15 control the seepage and asked if new piping would be installed. 0 Mr. Willenbring stated this will be hooked-up to existing 1988 piping. 17 Ms. Smith noted that the report stated that there was no property damage in this area yet there is 18 property damage. She questioned what material will be used in the depression and how long it 19 will last. She questioned if this solution was merely a band-aid for the problem. 20 Mr. Willenbring stated the City has experienced a lot of damage as a result of the flood in 21 different areas. The solutions considered included installing much bigger pipes to carry away the 22 water. This solution seems simple but that water will go to other cities and impact those cities. 23 This is not feasible based on the existing drainage laws and other jurisdictions that will not allow 24 a City to discharge more water downstream than currently is being done. 25 The City of St. Anthony is attempting to find a solution that will minimize the impact to 26 residents at a reasonable cost. WSB is suggesting to use the parks to hold water on a temporary 27 basis. It would not be in WSB's best interest to transfer the problem from one area to another. 28 Mr. Willenbring stated that if after the soil borings are received, it is determined that the water 29 will run through the soil toward the houses, an imperviable clay can be added to prevent this. 30 The process will include obtaining a detailed soil analysis, checking the water table and how 31 impervious the soil in this area is. Mayor Ranallo reported that when the City was attempting to obtain funding, one thing that was is stressed and the reason the request was approved by the DNR,was that the proposed solution 34 would not transfer water to another location.
