IV.6. Resolution for Approval of West Metro Multi-Community Wellhead Protection Plan (Part 1) and Agreement to Continue Participation in the Development and Implementation of the Remain CITY OF HOPKINS City Council Report 2025-040 To: Honorable Mayor and Council Members Mike Mornson, City Manager From: Eric Klingbeil, City Engineer Date: March 18, 2025 Subject: Approval of West Metro Multi-Community Wellhead Protection Plan _____________________________________________________________________ RECOMMENDED ACTION MOTION TO Approve Resolution 2025-017, Resolution for Approval of West Metro Multi-Community Wellhead Protection Plan (Part 1) and Agreement to Continue Participation in the Development and Implementation of the Remainder of the Plan (Part II) and authorize staff to sign the attached Letter of Support. OVERVIEW The state of Minnesota’s Wellhead Protection Program, administered by the Minnesota Department of Health (MDH), requires all public water suppliers to develop local wellhead protection programs to protect groundwater sources of drinking water. The city of Hopkins currently has a Wellhead Protection Plan approved by MDH in place, but these plans need to be updated at least every 10 years, sometimes sooner with major changes to the water supply system per the Wellhead Protection Rule (Minnesota Rules parts 4720.5100 to 4720.5590). The City is currently updating their Wellhead Protection Plan, but this time in conjunction with seven other communities in the West Metro that utilize the same water supply aquifer. Participating communities include Hopkins, Bloomington, Chanhassen, Eden Prairie, Edina, Minnetonka, Richfield, and Saint Louis Park. This is part of a pilot project with MDH and the Metropolitan Council to evaluate alternative drinking water planning approaches to the current “city-by-city” approach. The pilot project offers the opportunity to explore multiple benefits that a multi-community Wellhead Protection Plan may provide. The West Metro was selected for this pilot project due to the interest of local public water suppliers and the presence of many overlapping drinking water supply management areas (DWSMAs) that extend into multiple jurisdictions. The vision for this pilot project is to develop a coordinated and collaborative approach to protect and safeguard sub-regional drinking water sources that reduces barriers and improves local drinking water protection implementation in overlapping DWSMAs or where DWSMAs extend into a neighboring city. Part I of the Wellhead Protection Plan includes the delineation of a wellhead protection area and DWSMA, along with vulnerability assessments for the water supply wells and Engineering Department water supply aquifer. This Part I plan has been approved by MDH, as it has been determined to be in compliance with the Wellhead Protection Rule. The Part I plan was completed at no cost to the City by Barr Engineering under contract with the Metropolitan Council, who received a Clean Water Fund appropriation specifically for this work. The Wellhead Protection Plan will now continue into Part II of the plan, which includes determining goals, objectives, and management strategies for potential sources of contamination with the DWSMA. This Part II plan will also be a multi-community plan with the same communities that participated in the Part I, with specific management strategies for the City to complete within their jurisdiction. The Part II plan will be written by MDH and Minnesota Rural Water Association staff, with assistance from the Metropolitan Council, so there will be no funding needed from Hopkins to complete this plan. Due to the pilot nature of this project, there is not a hard deadline for the Part II to be completed, but it is estimated to be approved by MDH in Winter-Spring 2026. In order to ensure all governing bodies are on the same page, MDH is asking each participating community to approve the Part I plan and agree to continue the Wellhead Protection Plan process by completing and implementing a multi-community Part II plan.

Sincerely, Eric Klingbeil, PE City Engineer City of Hopkins Enclosure: Resolution 2025-017 cc: Sean Moilenen, Wellhead Protection Manager, Hopkins Abby Shea, Planner, Minnesota Department of Health Robyn Hoerr, Source Water Protection Specialist, Minnesota Rural Water Association Jen Kader, Senior Planner, Metropolitan Council 1 Safe and reliable drinking water is a public health priority for Minnesota Department of Health (MDH). Protection of drinking water resources under the State Wellhead Protection (WHP) Program is implemented on a city-by-city basis. As a result, each city has different implementation actions of their plan and a focus to protect their own drinking water source. The West Metro has many areas where one city’s drinking water supply management area (DWSMA) area extends beyond that city’s border; meaning a city may be dependent on the protection actions taken by their neighbor to protect their drinking water supply source. MDH, Metropolitan Council, and Public Water Systems (PWS) are evaluating alternative drinking water planning approaches to the current “city-by-city” approach with a pilot project. This pilot project offers the opportunity to explore multiple benefits that a multi-community WHP plan may provide. MDH will use the approaches and lessons learned from this pilot to evaluate new plan development and implementation options to consider during WHP Rule revisions. Vision Develop a coordinated and collaborative approach to protect and safeguard regional drinking water sources that reduces barriers and improves local drinking water protection implementation in overlapping DWSMAs or where DWSMAs extend into a neighboring city. Stakeholder Benefits for collaborative wellhead protection Benefits to Communities: • Collaboration by cities to protect shared, regional aquifers. • Use of updated regional groundwater model, at no cost to systems. • Reduced time required for individual city WHP planning and implementation. • Improved consistency in WHP implementation priorities based on same regional scale groundwater model, vulnerability assessment, and delineation work. • Coordinated and prioritized implementation activities on a sub-regional scale yielding more consistent and protective outcomes. • Improved local and State coordination and communication in managing drinking water resources. MULTI-COMMUNITY WELLHEAD PROTECTION (WHP) PILOT PROJECT 2 • Increased amount of grant dollars available by collaboration on projects. • Coordinated regional drinking water protection and understanding of how to protect drinking water across multiple cities. Benefits to Minnesota Department of Health: • Reduced time for WHP review and reduced number of plans needing review. • WHP implementation priorities based on same regional scale groundwater model, vulnerability assessment, and delineation work. • Improved local and State coordination and communication in managing drinking water resources. Benefits to Metropolitan Council: • Furthers mission to help improve drinking water resources across the metropolitan area. • Supports the work direction of the guiding committees, the Metropolitan Area Water Supply Advisory Committee (MAWSAC) and its Technical Advisory Committee (TAC). The proposed process will begin as: 1. MDH and Metropolitan Council, with the assistance of a consultant, update the regional groundwater model using the latest available datasets. Communities are asked to be aware and engaged during this phase of the project and share information for modeling, upon request. 2. Updated model and delineations available for communities to use for future WHP planning and implementation activities. Until regional delineation is completed, group members implement their individual plans collaboratively. 3. Participating communities use updated model and delineation for WHP planning for their community. 4. Communities in Pilot Group continue to work together to collaboratively manage WHP areas and protect source water. During delineation phase, group members explore options for governing ongoing plan development work and implementation for the regional DWSMA. 5. MDH and Metropolitan Council agree to provide funds to hire a facilitator to assist communities. This approach is likely to occur in some key phases: Subregional DWSMA delineation and assessment Pilot Group Established Collaborative Management Plan Collaborative Implementation MULTI-COMMUNITY WELLHEAD PROTECTION (WHP) PILOT PROJECT 3 Funding and technical assistance will be provided by both MDH and Metropolitan Council to support establishing the Pilot Group including: • Facilitation of all meetings with external facilitation support. • Hiring a consultant to work with communities to develop goals, implementation strategies, and activities to protect drinking water in the DWSMA. • Technical assistance from MDH and Metropolitan Council hydrologists and planners. • MDH extensions on existing WHP plan for participating communities. Participating communities will benefit from shared commitments and are asked to: • Be committed and stay engaged in the process. • Encourage community planners, city leaders, and neighbors to participate. • Explain project to others. • Attend meetings regularly. • Share project updates as requested. • Maintain open communication with MDH and Metropolitan Council. • Continue to implement existing Wellhead Protection Plan while regional plan is being developed. • Commitment to completing a regional WHP plan that can be supported and implemented by the communities. • Formulate a form of governing body or operating principles as a group. • Assist each other with funding/lobbying requests as needed. • Meet regularly and follow a group-established workplan to push for continuous improvement and source water protection.

The pilot project analyzed time of travel to 88 existing community supply wells and one planned supply well (Table 1). The wellhead protection area (WHPA) represents the area around the wells that contributes water to the community supply wells within a 10-year time period. The drinking water supply management area (DWSMA) fully envelops the WHPA and is defined by features on the surface such as roads, property lines, public land survey system (PLSS) area boundaries, etc. A new sub-regional groundwater flow model was developed from the existing Metro Model 3 regional groundwater model for the purposes of delineating the WHPA and DWSMA. This new model incorporated the most up-to-date geology and pumping information and was built using MODFLOW6, the most recent version of MODFLOW supported by the United States Geological Survey. The DWSMA area was determined through a combination of the sub-regional groundwater model, fracture flow calculations, and overland flow. Then the vulnerability was determined using a combination of the 40-acre PLSS quarter-quarter sections, water chemistry data, soils data, and geology. Much of the DWSMA is of low or moderate vulnerability with a few areas of high vulnerability (Figure 1). DWSMA vulnerability represents the sensitivity of the aquifer to impacts from land use and water management within the area. 2 Table 1.
