Planning & Zoning Board <br />September 8, 2021 <br />Page 3 <br /> <br />APPROVED MINUTES <br />filtration basins in their current position, surface water and possible contaminants can <br />reach the aquifer quickly. <br /> <br />Regarding the idea of prohibiting motorized watercraft, Mr. Evenson questioned how <br />many residents live on the lake. <br /> <br />Ms. Larsen said there are six property owners. <br /> <br />Mr. Evenson stated, since the property owners have resided there for a while, he <br />would oppose prohibiting motorized watercraft on the lake. <br /> <br />Mr. Wipperfurth wondered if the new homeowners would be able to remove the <br />raingardens and stormwater management ponds once they obtain ownership. <br /> <br />Ms. Larsen said the new owners would be required to maintain the raingardens and <br />the stormwater management ponds. She clarified stormwater maintenance <br />agreements are recorded against the properties and the agreements declare the <br />homeowners are responsible for the maintenance of the stormwater ponds. <br /> <br />Mr. Wipperfurth questioned if anyone checks whether the stormwater ponds are being <br />maintained or not. <br /> <br />Ms. Larsen explained the City is responsible for making sure private stormwater <br />ponds are being maintained. If the homeowner is not maintaining the pond, the City <br />has the ability to go in and maintain it. <br /> <br />Mr. Wipperfurth asked, since the homes are close to groundwater, does the City <br />require sump pumps or sump pits. <br /> <br />Ms. Gelhar said that question would be best addressed by the City’s Building <br />Official, Patrick Moonen. She stated she would ask Mr. Moonen and inform the <br />Board of his response. Regarding groundwater, Ms. Gelhar clarified, once our team <br />of engineers receives the low floor elevations based on the soil borings, they check to <br />make sure the houses are 4 ft. above groundwater. With this application, she <br />explained there were some instances where the engineers could not tell if the house <br />pads were 4 ft. above groundwater because they either did not encounter groundwater <br />or where they went down to was not 4 ft. from what the applicant was proposing. <br /> <br />The applicant, Tom Budzynski, commented sump pumps will be installed in every <br />house. He noted drain tile will be installed inside and outside and rock will be placed <br />under the basement floor. <br /> <br />Mr. Wipperfurth asked Ms. Gelhar what she uses to find groundwater. <br /> <br />Ms. Gelhar stated groundwater is normally indicated on the soil boring report.
