(Refer to report on file.) Public hearing opened at 5:37 pm. John Schulte of Jones, Haugh, and Smith was present representing applicant and owner. He said he was able to answer questions. Jayme Baker was also present. Effertz asked if there is just one access to the property. Kruschke said that is correct. Public hearing closed at 5:38 pm. Eickhoff asked if the access was so far to the south because of the roundabout. Kruschke said that is correct; they worked with Steele County to design this area. Eickhoff said he thinks this is a great use for the property.

Respectfully Submitted, ________________________________ Greg Kruschke Community Development Manager [PAGE 5] April 5, 2024 To: Planning Commission From: Community Development Department RE: Final Plat of Marthaler Addition. Background Jayme Baker, Marthaler Automotive on behalf of John Ihlenfeld and the Ihlenfeld Family Partnership, a request for final plat of Marthaler Addition, a one lot commercial lot for the purposes of constructing an automotive dealership and ancillary uses. The property owner has requested annexation of this parcel and is progressing through that process. All utilities for the project are available. Sanitary Sewer will need to be extended south along the east side of State Avenue. Due to the depth of the Sanitary main an additional written easement will be required at the width required by the City Engineer. A service line will then be bored under State Avenue to service the property. Water is existing along the east side of State Avenue. Although the water main exists, there are no hydrants between 26th Street and the Dog Park, which is roughly 1600’ of distance. Hydrants are required at every 400’. Two hydrants will need to be installed along State Avenue to meet spacing. A development agreement will be required for the public improvements required for this development. Access for the property is proposed to come from a shared access drive to be constructed just to the south of the platted property. A shared driveway easement will need to be provided along with the final plat for recording. This agreement shall address the access, maintenance, as well as any triggers and cost sharing for the privately shared driveway.

Water is existing along the east side of State Avenue. Timing/Financing of Development: The applicant is hoping to record the final plat soon and start construction this spring. Outstanding Assessments: None Floodplain: None Wetlands: None Storm Water Drainage: The applicant is proposing to construct a pond on the north side of the property. Easements: The applicant is proposing to dedicate a 10’ utility easement along the entire perimeter of the plat. A shared driveway easement will be needed for the access point on the southeast side of the property. County/MNDOT Review: Notices have been sent to both. The County has preliminarily agreed to the access point. MNDOT has not commented as of the time of this report. [PAGE 7] Staff Review: Staff recommends approval of the final plat of Marthaler Addition with the following conditions: 1) The final plat shall be approved within one year of the date of approval of the preliminary plat. 2) The title opinion shall be approved by the City Attorney prior to recording of the final plat. 3) The developers shall enter into a development agreement with the City prior to recording of the final plat. 4) MN Plumbing code requires an open trench for sanitary sewer that is installed within private property.
