Proposed Senior Living Facility—Mounds View, Minnesota Kilo Project 25-2066—December 30,2025 Page 6 of 9 While it may be possible to generate higher soil bearing pressures, more intensive analyses, including SPT borings, laboratory testing, and settlement analyses would be required to determine the allowable bearing pressure given allowable settlement tolerances. Correlated bearing capacities of up to 2,000 pounds per square foot were observed at depths of 22 inches or deeper in this exploration, and these bearing pressures can be improved by compacting the sand soils during construction. No elevation data was captured by Kilo during the field exploration, and none was authorized in the scope of services. Stormwater Management Recommendations As sites are developed, the construction of man-made impervious features such as pavements and building roofs reduce the capacity of a site to infiltrate stormwater into the subgrade and increases the peak runoff generated by a given land area in a given storm. As a result of the increase in impervious area, more of the stormwater volume becomes runoff instead of infiltrating into the ground. With this increase in impervious area, contaminants such as salts, sediment, and debris can be carried by the runoff and eventually pollute lakes, streams, and rivers. In order to reduce the risks of this problem, the Minnesota Pollution Control Agency requires on-site storage, infiltration, and treatment of stormwater as part of the Stormwater Permit prior to discharge off-site. This is typically through the use of stormwater management ponds, below-grade storage, or as part of a capture and beneficial reuse process. No design plans were provided to Kilo for stormwater management areas at the time of this report. This report is based on the soil types generally encountered on site, and additional exploration may be necessary once stormwater feature locations are available.
