This study area is located in the southwestern portion of Oakdale, and is more specifically bounded to the south by 10th Street N (County Road 10), to the west by Geneva Avenue N (Highway 120/Century Avenue), to the north by 14th Street N, and to the east by various property lines. The study aims to address area land uses, market analysis, and transportation issues. In general, the study area contains several aging commercial properties, and several redevelopment projects in the area have been proposed in the past. To study the area, the City has partnered with the Urban Land Institute’s (ULI) Technical Assistance Panel (TAP) program. Unlike a traditional study, the TAP program utilizes an intensive workshop process over two days which brings together industry professionals to analyze the study area, engage area stakeholders, and prepare recommendations. To help fund the TAP, the City was awarded a predevelopment grant from the Washington County Community Development Agency. The 12th and Geneva TAP was conducted on April 29 and April 30. Engagement efforts conducted by ULI and City staff included a public survey, mailers to property owners and businesses, stakeholder interviews, and a reception event with area stakeholders and elected officials. The public survey received a total of 254 responses. With the TAP now complete, ULI staff and panel members have prepared a presentation outlining initial findings and recommendations for Council consideration. Input from the City Council will be used to draft a final report which will be shared with Council but is not intended to be formally adopted. It should be noted that the site layout drawings drafted by TAP panelists are conceptual in nature and intended as an illustrative tool rather than a formal site plan. COUNCIL DIRECTION REQUESTED It is requested that the City Council provide input on the content of the initial findings and recommendations of the 12th and Geneva TAP.

POET Inventory and Water Modeling The first report identified private wells in Oakdale that may need treatment in the future, either with Point of Entry Treatment or connections to the City water system. The second part of the study confirms the relocation of wells, as reflected in the 3M Settlement Final Drinking Water Supply Plan – sealing of Wells 1 and 2, and drilling new wells 11 and 12, will not adversely affect the operational pressures and fire flows within the Oakdale water system. Water System Study The second report provides an update to the City’s water supply plan to assure system adequacy for future growth and treatment. The report refines the proposed improvements needed for treatment and updates the costs associated with addressing PFAS in the ground water source. COUNCIL DIRECTION REQUESTED No Council direction is requested for the POET and Water Modeling Report. The Water System Study recommends the construction of a centralized treatment plant, the relocation of two wells, the rehabilitation of the existing treatment plant, and the decommissioning of Well No. 8 and conversion to a Pressure Reducing Valve (PRV) building. Staff is requesting that the Council consider supporting the submittal of grant applications for the design of the improvements noted above, and an addendum to address if PFAS levels in Wells 3 and 10 exceed lowered thresholds.

INTRODUCTION The City of Oakdale has requested a report on which private wells within the community may need Point of Entry Treatment (POET) systems as part of the Final Drinking Water Supply Plan (FDWSP). In addition, the City of Oakdale wants to confirm the water system operating pressures will not significantly change as a result of removing Well No. 2 from the south zone and centralizing the supply wells in the vicinity of the proposed water treatment plant to be located at 1900 Hadley Avenue North. II. BACKGROUND The City of Oakdale has been dealing with Per-and Polyfluorinated Substances (PFAS) in the ground water supply wells since 2005. In 2018, the state of Minnesota settled its lawsuit against the 3M Company in return for a settlement of $850 million. Minnesota’s attorney general sued 3M in 2010 alleging that the company’s production of chemicals known as PFAS had damaged drinking water and natural resources in the Twin Cities Metropolitan Area. After legal and other expenses are paid, about $720 million will be invested in drinking water and natural resource projects in the Twin Cities east metropolitan region, including the City of Oakdale. The Minnesota Pollution Control Agency (MPCA) and Minnesota Department of Natural Resources (DNR) are co-trustees of these funds. As co-trustees they are responsible for carrying out the terms of the settlement agreement and allocating the funds for the purposes noted in the settlement agreement which include: Priority 1 — Ensure safe and sustainable drinking water With PFAS having contaminated domestic water supplies in a number of southeast metro communities, the top priority for grant funds will be projects aimed at providing a clean, sustainable supply of drinking water in the area. Priority 2 — Enhance natural resources The second priority for grant spending is to enhance aquatic resources, wildlife habitat, and outdoor recreational opportunities in the east metropolitan area, or downstream of the area on the Mississippi and St. Croix Rivers. To satisfy the requirements of Priority 1, the FDWSP was developed and included projects to treat Oakdale’s private wells that are or may become contaminated over time by hooking up to the public water supply system, or by installing Point of Use Treatment Systems (POETS) where hooking up is not feasible. The FDWSP also included improvements to the city’s public drinking water system through a centralized treatment plant. III. TREATMENT OF PRIVATE WELLS THROUGH THE USE OF POINT OF USE TREATMENT SYSTEMS The FDWSP indicated that no private wells would need POETS initially however there may be four future locations needing POETS based on the particle tracking study. The consultant working for the co-trustees was contacted and provided information on the private wells in Oakdale. Contact was made with the city’s utility clerk to confirm which parcels are currently served and billed for Prepared by: Bolton & Menk, Inc. INTRODUCTION POET Inventory & Water Modeling ǀ 0N1.132652 Page 1  city water service. The spreadsheet in Appendix A shows the private wells within the city limits and within the Special Well drilling zone. The four parcels/wells at the top of the spreadsheet were identified as possibly needing POETS in the future based on the particle tracking study. One of the wells (UWN 270045) has already been sealed in preparation of redevelopment of the property. Two other wells (UWN 686253 & 1000024002) are already connected to the city water system therefore POETS are not needed for these wells (city’s utility clerk confirmed). The only active well remaining on the initial list is the Oak Marsh Golf Course well (UWN570405) which is used to irrigate the golf course. According to their own records this well pumped 1,712,400 gallons in 2015 & 1,124,640 gallons in 2016. The golf course does have the ability to reuse storm water from the golf course and neighboring residential area. According to their records, they applied 12,604,800 gallons in 2015 and 12,653,120 gallons in 2016, therefore they were recycling 7.36 gallons and 11.25 gallons of runoff for every gallon they pumped in 2015 and 2016. If the golf course was using city water for irrigation purposes, it would have added approximately 0.14 gallons per capita day consumption for those years. There is one property that had a risk index of less than 0.5 based on the health-based values in 2019. It is recommended this well be re-evaluated with the new health-based values to determine if the risk index is still less than 1.0. This parcel is highlighted in orange (7515 10th Street North). This property has the ability to hook up to city water. To avoid future monitoring, this property owner should be encouraged to connect to the city’s water system. There are two properties (3301 & 3307 Geneva Ave N) with wells with no detection in 2019, however the particle tracking indicated they could be affected in the future. These wells should be tested to confirm they still have a risk index less than 1.0. If treatment is necessary POET systems are appropriate for these two private wells. There is one property (3465 Geneva Ave N) that is outside of the Special Well drilling zone but right on the border, that may want to consider hooking up to the city’s public water system. Recently private wells along Olson Lake Trail and Sunburrow Addition have tested positive and have PFAS levels above the Health Risk Indexes. There are 27 private wells in this area, three of which already have POET systems installed. In addition, there are three vacant lots that could have future POET systems. In summary there are 27 total future POET systems that will be needed to treat private wells. IV. IMPACT ON WATER SYSTEM PRESSURES RESULTING FROM SEALING WELLS 1 & 2 AND INSTALLING THREE NEW WELLS CLOSER TO THE CENTRALIZED TREATMENT PLANT & RELOCATING THE 7th/HADLEY PRESSURE REDUCING VALVE System Pressure Impacts The FDWSP for Oakdale shows the sealing of Wells 1, 2 & 7 and drilling three new wells in the vicinity of the centralized treatment plant at 1900 Hadley Avenue. Wells 1 & 7 are in the central pressure zone, and Well No. 2 is in the south pressure zone. The three new wells would all be in the central pressure zone. The relocation of wells has the potential to reduce operating pressures and fire flows in the areas surrounding the existing well locations and increase operating pressures in the areas surrounding the new well locations. The City is also interested in relocating a pressure reducing valve (PRV) from a pit at the intersection of 7th Street & Hadley Avenue to the Well No. 1 location and repurpose the existing well house for the PRV. Placing the PRV above ground in a Prepared by: Bolton & Menk, Inc.

A modeling study was done to determine the changes in operating pressures and fire flows resulting from sealing and relocating these wells under conservative scenarios including maximum daily demand (MDD) conditions, and MDD with fire flow conditions. Three alternatives were developed and modeled with the following scenarios 1) existing conditions 2) new wells, 3) new wells and a relocated PRV, and 4) relocated PRV only. The results are in the table below indicate little change in operating pressures. Table 1 – Pressure Comparison Scenario Pressure (psi) Scenario No. South Zone Central Zone North Zone Existing 31 - 78; 57 - 101; 49 - 84; 1 System Avg. 55 ±11 Avg. 82 ±9 Avg. 68 ±7 31 - 78; 57 - 102; 49 - 84; 2 New Wells Avg. 55 ±11 Avg. 82 ±10 Avg. 68 ±7 New Wells + 31 - 78; 57 - 102; 49 - 84; 3 Relocate PRV Avg. 55 ±11 Avg. 82 ±10 Avg. 68 ±7 31 - 78; 57 - 101; 49 - 84; 4 Relocate PRV Avg. 55 ±11 Avg. 82 ±9 Avg. 68 ±7 The results show that pressures stay within the desired range for each alternative. Pressures are not affected by scenarios in the north or south zone. Pressure is marginally affected in the central zone for scenario no. 2 and no. 3, this is due to the abandonment of Well 1 and the introduction of new wells at the water treatment plant. Fire Flow Impacts Fire supply rates are typically dictated by ISO (insurance Services Office) standards which affect the level of insurance and rates throughout the community. Available fire flows ranging from 2,000 to 5,000gpm provide a very good level of fire protection. The results below suggest that the south pressure zone’s fire flows are impacted the most by the proposed alternatives involving the relocation of the PRV, while scenario no. 2 seems to have no effect, and the central and north pressure zones appear unaffected. The souths zone’s fire flows are negligibly affected by scenario No. 2 with some hydrants dropping by 20 gpm at most. The south zone is affected by the relocation of the PRV. Relocation of the PRV creates a longer bottleneck to the south pressure zone compared to the existing system. The existing system’s PRV has 12-inch watermain to the south and a 10-inch loop to the north which connects to a 12-inch watermain further north. The relocated PRV connects to 8-inch watermains to the north and south which constrict fire flow capacities compared to the existing system. The central and north zone’s fire flows are not affected by any of the scenarios. Prepared by: Bolton & Menk, Inc.

The relocation of the PRV with the new wells results in decreases in fire flow capacities in the south zone. The relocation of the PRV also results in a decrease in fire flow capacities for the south pressure zone. Prepared by: Bolton & Menk, Inc.

All resulting available fire flow averages are well within the ISO range. According to the Public Protection Classification Summary Report dated October 1, 2023, the City currently has an ISO rating of 3 (PPC grade points ranging from 70.00 to 79.99) with an earned credit of 74.94. The water supply system accounts for 40% of the total classification, of which the city received 27.34 earned credits of 30 credits available attributable to the water supply system.

Depending on the source of funding, composition of assets, or the specific City Council or Management direction, fund balance is classified between the following: Nonspendable – Cannot be spent as either not in a spendable form or legally required to be maintained intact. Examples include inventory and prepaid items. Restricted – Legally enforceable constraints placed on a funds use. Examples include restricted funding sources due to creditors, laws, or voters (federal police forfeiture, charitable gambling). Committed – Unrestricted funds with constraints imposed by formal action of the City Council. Example includes the Economic Development Fund. Assigned – Unrestricted funds with constraints inherently imposed by the purpose of the fund. This is the primary unrestricted type for all funds other than the General Fund. Unassigned – Residual amounts in the General Fund not reported in any other classification. All other funds would only have unassigned fund balance if fund balance was negative (liabilities greater than assets). The General Fund does have a minimum unassigned fund balance. The calculation is found in City Policy FR-019: Fund Balances, “maintain a minimum unassigned General Fund balance in a range between 5.5 and 6 months (45.83% and 50.00%) of the subsequent years budgeted expenditures”. Preliminary numbers for the minimum are as follows: 1 Governmental Fund Balances Below are preliminary fund balance amounts for the governmental funds (all funds except the Enterprise Fund): The Restricted balances are: Special Revenue – Police Forfeiture, Local Affordable Housing Aid, and Charitable Gambling. Debt Service – Levy and assessments collected for debt service. Capital Projects – Unspent bond proceeds, park dedication, unspent local option sales tax, tax increments collected. The Committed balances are: Special Revenue – Community and Economic Development and Pandemic Business Loans. The Assigned balances are: Debt Service – Closed Bond Fund. Capital Projects – Unspent Capital Improvement Plan (CIP) funds (Park, Vehicles & Equip, Utility System Replacement, etc.), interfund receivable. The negative Unassigned balance is primarily due to the recognition of the interfund loan for the purchase of the Tanners Lake parcels. Enterprise Net Position Enterprise funds record Net Position instead of Fund Balance. Below are preliminary net position amounts for the enterprise funds: COUNCIL DIRECTION REQUESTED At this work session, staff would like to hear from Council on the City’s estimated 2024 Fund Balances with emphasis on the Committed, Assigned, and Unassigned balances. Attachment City Policy FR-019: Fund Balances 2  Standard Operating Policy City of Oakdale Policy Number: FR-019 Pages: 4 Subject: Fund Balances Approved: 2011 Amended: 09/2023 1.0 Purpose 1.1 The purpose of this policy is to create fund balance classifications to allow for more useful fund balance reporting and for compliance with the reporting guidelines specified in Statement No. 54 of the Governmental Accounting Standards Board (GASB). 1.2 The policy of the City of Oakdale is to comply with GASB Statement No. 54. To the extent a specific conflict occurs between this policy and the provisions of GASB Statement No. 54, the GASB Statement shall prevail. 2.0 Fund Balance Definitions 2.1 Fund Balance The difference between assets, deferred outflows of resources, liabilities, and deferred inflows of resources reported in a governmental fund. 2.2 Nonspendable Fund Balance Amounts are comprised of funds that cannot be spent because they are either not in spendable form or are legally or contractually required to be maintained intact. They include items that are inherently nonspendable, such as, but not limited to, inventories, prepaid items, and long-term receivables. 2.3 Restricted Fund Balance Amounts are comprised of funds that have legally enforceable constraints placed on their use that either are externally imposed by resource providers or creditors (such as through debt covenants), grantors, contributors, voters, or laws or regulations of other governments, or are imposed by law through constitutional provisions or enabling legislation. 2.4 Committed Fund Balance Amounts are comprised of unrestricted funds used for specific purposes pursuant to constraints imposed by formal action of the City Council of the City of Oakdale and that remain binding unless removed by the City Council through subsequent formal action. The formal action to commit a fund balance must occur prior to December 31st; however, the specific amounts actually committed can be determined in the subsequent fiscal year. A committed fund balance cannot be a negative number. 1 2.5 Assigned Fund Balance Amounts are comprised of unrestricted funds used constrained by the City of Oakdale’s intent that they be used for specific purposes, but that do not meet the criteria to be classified as restricted or committed. In governmental funds other than the General Fund, the assigned fund balance represents the remaining amount that is not restricted or committed. The assigned fund balance category will cover the portion of a fund balance that reflects the City’s intended use of those resources. The action to assign a fund balance may be taken after the end of the fiscal year. An assigned fund balance cannot be a negative number. 2.6 Unassigned Fund Balance Residual amounts in the General Fund not reported in any other classification. Unassigned amounts in the General Fund are technically available for expenditure for any purpose. Unassigned fund balance will occur only in the General Fund or in other funds when there is a negative fund balance that cannot be eliminated by reducing restricted, committed, or assigned fund balances. 3.0 Governmental Fund Definitions 3.1 General Fund The General Fund is established to account for all revenues and expenditures which are not required to be accounted for in other funds. Revenue sources include property taxes, license and permit fees, fines and forfeits, program revenues, intergovernmental revenues, investment interest earnings, and transfers. The General Fund’s resources finance a wide range of functions including the operations of general government, public safety, and public works, and community services and recreation. The General Fund may have committed or assigned fund balances at year end for budget carryovers. The General Fund may have a portion of its fund balance classified as nonspendable if there are long term receivables, inventories, or prepaid items on the balance sheet. 3.2 Special Revenue Funds Special revenue funds are used to account for and report the proceeds of specific revenue sources that are restricted or committed to expenditures for specified purposes other than debt service or capital projects. Governmental accountings standards require that substantial inflows of revenues into a special revenue fund be either restricted or committed in order for the fund to be considered a special revenue fund. 3.3 Debt Service Funds Active Debt Service Funds with outstanding debt are considered restricted; they include resources that are being accumulated for payments of principal and interest maturing in current and future years. All of the City of Oakdale’s debt service funds are considered restricted. Closed Debt Service Fund balances are considered assigned fund balances and are used to cover deficits in other active debt service funds. 2 3.4 Capital Project Funds Capital project fund balances are resources that are being accumulated for current and future projects and are considered either restricted or assigned fund balances. Capital project funds are used for and report financial resources that are for capital projects, including the acquisition or construction of capital facilities and other capital assets. 4.0 Classification of Fund Balances 4.1 The City of Oakdale shall classify its fund balances in its various funds in one or more of the following five classifications: nonspendable, restricted, committed, assigned, and unassigned. 5.0 Fund Balance Order of Use 5.1 When both restricted and unrestricted resources are available for use, the City first uses restricted resources, then unrestricted resources as they are needed. When committed, assigned, or unassigned resources are available for use, the City uses resources in the following order: 1) committed, 2) assigned, and 3) unassigned. 6.0 Minimum Fund Balance and Reserves 6.1 General Fund Working Capital The City of Oakdale will strive to maintain a minimum unassigned General Fund balance in a range between 5.5 and six months (45.83% and 50.00%) of the subsequent years budgeted expenditures for working capital, which will avoid issuing short-term debt to meet the cash flow needs of the current operating budget during the time between significant collection of major revenue sources such as property taxes. The City Council shall approve any transfer of excess fund balance in the subsequent year. In the event the unassigned General Fund balance will be calculated to be less than the minimum requirement at the completion of any fiscal year, the City will attempt to replenish the General Fund to the percentage noted above. 6.2 Special Revenue and Capital Project Funds The City will maintain reserves in the Special Revenue and Capital Funds at a level sufficient to provide working capital for current expenditure needs plus an amount of cash that is estimated to be needed to meet legal restrictions and pay for future capital projects. 6.3 Enterprise and Internal Service Funds The City will maintain reserves in Enterprise Funds at a level sufficient to provide adequate working capital for current expenditure needs, replacement of capital assets within the fund over their estimated useful life, and to pay for future capital projects. Judicious use of reserves within funds can be used to moderate fluctuations in capital projects and infrastructure maintenance expenses. 3 7.0 Committing Fund Balance 7.1 A majority vote of the City Council is required to commit a fund balance to a specific purpose and subsequently to remove or change any constraint so adopted by the City Council. 8.0 Assigning Fund Balance 8.1 The City Council delegates the power to assign fund balances to the City Administrator and Finance Director. 9.0 Review 9.1 The City Council will conduct an annual review of the sufficiency of the minimum unassigned General Fund balance level through the budget process. 4
