<br /> <br />Planning Commission Minutes <br />August 27, 2024 <br />--------- <br />Page 6 of 8 <br /> <br />Mr. Carlton stated this application affects only the proposed 217 acres. He outlined the project <br />boundaries and explained the updated sewer connections offered a smaller lot size opportunity, rather <br />than a 2.5 acre. He stated this area is surrounded by wetlands. <br /> <br />Ms. Gillette asked if there would even be a connection to County Road 1 through her parent's <br />property. She felt the wetlands would be affected by the proposed development, with each lot having <br />their own well. She asked if a groundwater survey was taken and data available for how this will impact <br />the surrounding landowners. She stated the land to the north contains unique plants that have been <br />protected and studied, and feels those plant species and endangered species that will be affected by this <br />development. Minnesota Land Trust is interested in preserving this area as an asset to the city. She <br />asked about soil types, well depths, what proposed utilities will be included and what the setbacks will <br />be. <br /> <br />There being no one else to speak, Acting Chair Johnson closed the public hearing. <br /> <br />Chris Dahn, an engineer with Bogart Pederson and Associates, discussed the process and methods <br />when modeling the wetlands to approximate drainage from the subdivision to the wetlands, using an <br />approximate number of impervious that could go onto each lot, run off amounts on each site, and the <br />effect it has on the surrounding wetlands, all details are in the submitted stormwater report. He <br />discussed the groundwater report details, and stating the proposed 100 homes would not have an <br />impact on the groundwater. Mr. Dahn then discussed endangered species and wasn't aware of any. He <br />stated the soil types and borings completed throughout the entire plat, required on the roadways and <br />stormwater basins, and go down at least 3' below the groundwater location to prevent contamination. <br /> <br />Commissioner Booth asked a question about the runoff and where it's going. <br /> <br />Mr. Dahn explained there will be 18 different infiltration basins installed to manage the runoff from the <br />impervious surface into the ditches, to the infiltration basins. <br /> <br />Commissioner Rydberg asked if the road alignment at the eastern connection could be adjusted. <br /> <br />Mr. Carlton stated that as it currently sits, the property line for the neighboring parcel is not included in <br />the proposed subdivision, and therefore limits where the roadway connection can be placed. <br /> <br />Ben Schmidt – owner of Twin Cities Land Development – stated at this time, the roadway alignment <br />across cannot be made. He said the wetland study did not identify any endangered species but does <br />recognize this area to be an asset and one they wouldn't want to see disturbed. He said the large <br />wetland will be in an outlot to protect the area with either the city or the HOA owning it. <br /> <br />There being no one else to speak, Acting Chair Johnson closed the public hearing. <br /> <br />Commissioner Rydberg asked about the differences between the R1a and R1b zoning. <br /> <br />Mr. Carlton stated the minimum lot size for a R1a lot is 2.5 acres, R1b for sewered lots, minimum lot <br />size is 12,000 sq. ft.; Rb1 for non-sewered lots the minimum lot size is 1 acre. <br /> <br />Commissioner Rydberg wondered if they should be concerned with the potential for an increase in <br />residents requesting variances, zone changes, or adjustments when there are larger lots, and will they DRAFTPage 7 of 27
