Larson Engineering, Inc. <br />3524 Labore Road <br />White Bear Lake, MN 55110-5126 <br />651.481.9120 Fax: 651.481.9201 <br />www.larsonengr.com <br /> <br /> <br /> <br /> <br /> <br />MEMORANDUM <br /> <br />To: Nathan Fuerst, City Administrator, City of Lake Elmo <br />From: Greg Buchal, PE – Larson Engineering, Inc. <br />Date: February 27, 2025 <br />Project: 12246044 <br />Subject: Additional Submittal to City of Lake Elmo on Behalf of Independent School District <br />#834 for the Oak-Land Middle School 2025 – 2026 Additions & Renovations project, <br />located at 820 Manning Avenue North. (PID# 36.029.21.11.0002 and <br />36.029.21.11.0003) <br />Oak-Land Middle School - Additional Analysis of Irrigation Alternatives <br /> <br />The Conditional Use Permit application was submitted and approved by the City Council on <br />October 1, 2024. As one of the conditions of approval for the CUP, the School District was to <br />provide a list of alternative methods to supply water for irrigating a portion of the property. This <br />information was provided in November of 2024, and since then additional backup and elaboration <br />of these methods was requested. The information below is a response to this request and no <br />revision to the approved Conditional Use Permit is being requested. For context, the Conditional <br />Use Permit complies with the current ordinances and the scope of irrigation is to only irrigate <br />those areas currently being irrigated with no expansion planned. <br /> <br />The City Planner has requested that additional information and analysis be provided for three <br />items; irrigation of the athletic fields utilizing well water; irrigation of the athletic fields utilizing <br />water re-use from storage tanks; and irrigation of the athletic fields utilizing water re-use from <br />Lake Rose. Another option being considered by the School District is to not irrigate any of the <br />fields. <br /> <br />As indicated in the previous Memorandum to the City of Lake Elmo in November of 2024, the <br />School District has made connecting to municipal water a high priority for the Oak-Land Middle <br />School, due to potential future health and safety concerns, and ongoing maintenance costs related <br />to having well-water at the school. This current building addition project provides the <br />opportunity to improve that infrastructure at the school. <br /> <br />With a new municipal water service to the school building, the existing irrigation system for the <br />athletic fields could be utilized and very little improvements, modifications, or costs would be <br />incurred, since the existing connection for the irrigation water remains within the school building. <br />Rain sensors would be added to eliminate irrigation operation when rain events have provided <br />adequate water to the athletic fields. This is the School District’s preference and they understand <br />that irrigation restrictions could occur in times of drought and would abide by all City of Lake <br />Elmo related ordinances regarding water use for the athletic field irrigation.
