Suzanne Dvorak, 14640 Potassium Street NW, Ramsey, noted that the previous property owner <br />at 14660 Potassium Street did have a sandpoint in the ground for watering. <br />The Maults were not aware of any such pipe. <br />Councilmember Kurak stated that if there is a pipe in the ground there is the possibility that it <br />could be leaking. <br />Assistant Director of Public Works Olson stated that if the dewatering activity is causing the <br />water tables to rise it still would not explain why the residents have seen a high water level all <br />summer because the dewatering activities did not start until September. Staff has been out to the <br />area and understands their concerns, which is why staff suggested the possibility of brining in <br />some fill to raise the grade while construction is going on. <br />Ms. Mault replied that bringing in fill would not save her trees. <br />Mr. Mault inquired as to what replaces the water that was in the ground after the dewatering is <br />completed. <br />City Engineer Jankowski explained that the ground water replaces itself and retains the existing <br />position. <br />Mr. Mault inquired if dewatering causes the ground to shift. <br />City Engineer Jankowski replied no. <br />Councilmember Cook stated that it seem as if the problem is being caused by ground water not <br />surface water. <br />Assistant Director of Public Works Olson replied that the situation is definitely not being caused <br />by surface water. <br />Councilmember Kurak stated that when Village of Sunfish Lake started dewatering they ran the <br />water over to Sunfish Lake and the level of the lake became very high. She would have to assume <br />that when they start raising water up in one spot it has to find a place to go underground and it <br />could have very well drained back into the low area. <br />Assistant Director of Public Works Olson stated that the most logical dewatering activity that <br />would be impacting this area would be from the Alpine Acres development because the wetlands <br />are at the same elevation, but it does not explain the whole summer worth of wet conditions. <br />Councilmember Zimmerman stated that they would probably have to continue to watch the area <br />over the next year to see what happens. <br />Public Works Committee/October 21, 2003 <br />Page 3 of 8 <br />
