Highway 96 Arden Hills, MN 55112 651.792.7800 www.cityofardenhills.org Agenda Board Meeting Convenes at 6:30 PM CALL TO ORDER/ROLL CALL 1. APPROVAL OF THE AGENDA 2. APPROVAL OF MINUTES of the previous meeting Jan 13, 2026 3. PUBLIC INQUIRIES 4. ANNUAL ELECTION 4.1. Background: There are currently 3 seats available in this election: Linda Hansohn, Kent Stennes and Renee Marino. Renee is currently filling the vacancy left by Susan Johnson and the person that will filling that seat will be valid until 2028, Linda and Kent’s seats will expire in 2029. 4.2. Action: Determine the list of candidates and provide secret ballots to all attendees. Tally votes and determine new Board members 5. OLD BUSINESS 5.1. 2026 PMP and Karth Lake Pump System updates. David Swearingen 5.1.1. Background: The streets on the north side of Karth lake will be undergoing a pavement rehabilitation project in 2026. This project will include work on the Cummings Park retaining wall and lake pump system. A special meeting on 4-7-2026 was held to determine if the resolution signed on 1-13-2026 was still acceptable given the new pricing. 5.1.2. Action: Get an update from David about the project and determinations made by City Council regarding pump system upgrade and final levy. 5.2. Water quality monitoring for Karth Lake for 2025. Gary Gerding 5.2.1. Background: The KLIDB has participated in the Citizen-Assisted Monitoring Program (CAMP) with the Metropolitan Council by coordinating volunteer sampling of Karth Lake’s water quality since 2006. 5.2.2. Action: Provide any updates for 2025 sampling program. 5.3. Ice in/out dates for the past several years. Gary Gerding 5.4. PMP1 project plan. David Swearingen 5.4.1. Background: Now that large areas have been clear cut, we would like David to provide additional detail and updates about the revegetation plans for the retaining wall and holding pond areas. Since this is an annual meeting, it would be helpful if David could review the drawings in the request for proposal document for those sites so both the board and the public can understand the final design. Are there details beyond those drawings such as revegetation plans?. Will there be trees and shrubs planted or will it just be grass-seeded mat that was placed on all of the graded areas of the BMP1 site? 5.4.2. Action: The plans calls for MnDOT Type 20 (Southern Shortgrass Roadside - SSR) which is a specialized native seed mix designed for full sun to part-shade, dry soil areas in southern and central Minnesota. It supports pollinators, requires minimal mowing, and is ideal for inslopes and medians. 5.4.2.1. Purpose: Erosion control, roadside stabilization, and pollinator habitat in dry, sandy, or rocky soils. 5.4.2.2. Species Composition: Typically includes shortgrass prairie species suitable for drought-prone areas. 6. NEW BUSINESS 6.1. Plan for 2026 removal of Purple Loosetrife. Verify that we have the permit. 6.2. Update on the DNR lake gauge and current lake level. 6.2.1. The lake gauge was installed on Renee’s shore on 4/9 and the current water level is 934.31. That is close to the DNR "pump-off" level. She plans to keep David apprised weekly going forward so that once he knows the construction schedule and the period of time when pumping will not be available, he can make a call on whether to pump ahead of that period.)

ADJOURN Draft Minutes for Karth Lake Improvement District Board Regular Meeting 6:30 PM, Tuesday, January 13, 2026 CALL TO ORDER/ROLL CALL The meeting was convened at: 6:30 PM. Present: Board Members: Joel Gerich, Chair, Andrew Elmquist; Kent Stennes; Gary Gerding; Melissa Jannakos Staff Liaison: David Swearington, Public Works Director Visitors and Karth Lake Improvement District members: Renee Marino Absent: Board Members: Linda Hansohn, Secretary; 1. APPROVAL OF AGENDA: The agenda was approved 2. APPROVAL OF MINUTES: The minutes of the previous meeting on Octobrt 14, 2025, were approved with a modification to 4.3.2 to just indicate that secchi depth was shallower all season and correct the next meeting date. 3. PUBLIC INQUIRIES: None. 4. OLD BUSINESS 4.1. Possible outreach to attract another Board member. Joel 4.1.1. Background: Joel has been actively pursuing new possibilities. 4.1.2. Action: Joel has talked to several neighbors about joining the board but at this time no one has expressed real interest. Renee has volunteered to fill the empty seat left by Susan Johnson. The Board voted to approve her filling of that seat until the April election where someone will be chosen to fill out the remaining term. 4.2. (Combine agenda items 4.2 and 4.3) 2026 PMP and Karth Lake Pump System updates. David Swearingen 4.2.1. Background: The streets on the north side of Karth Lake will be undergoing a pavement rehabilitation project in 2026. This project will include work on the Cummings Park retaining wall and lake pump system. Discuss pump proposal and Geocell information for the Cummings Park retaining wall as part of the 2026 PMP project as well as any other updates. 4.2.2. Action: • There have been discussions in the city council discussing pump improvements and cost sharing. They have decided to split the cost 50-50 and requested that the KLIDB create a resolution indicating the recommended terms for the pump improvements. • The determination has been made to go with option two from the feasibility report. Originally, the thought was that we could use the current control panel but that has been determined to not be possible. As a result, the estimated cost has gone from $112,000 to $185,000. This estimate does include a 37% construction contingency so the final number may be lower. Rice Creek watershed has agreed to contribute $56,000 to the project (since the cost increase, the city is asking if Rice Creek would contribute another $10,000 but we don’t know if that will happen). The amount charged to each property is based on the property tax value but each of 46 properties would pay an average of $1000. Any extra we might get from Rice Creek would be used to bring the total down with the city contribution 50%. • The plan will include a culvert in the retaining wall for the pump system. With a manhole to access the pump. The pump will need to be put in and removed seasonally since it can’t be frozen. • The new control panel will automatically turn on and off the pump at the 935.5 and 935 water levels automatically and there will be notifications sent to city personnel if there is a malfunction as well as the status of the pumping. • The existing retaining wall will be replaced by a geocell system that will follow the natural slope of the surrounding shoreline. Native plants will be placed in the cells of this new system. • This project will include the work on BMP phase 2 project recommended by Rice Creek watershed which will expand the runoff pond from the business park area, avoiding impact on any wetlands in the area. The trees in both the runoff pond area and the retaining wall area will be cleared before March 31. • There was a discussion about a possible temporary railing near the new runoff pond since it will be close to the trail. Once brush filled that area in, it would be less of a concern. • There was also discussion about extending the asphalt to the lake along the area that currently has a trail worn down from fishing people. This was determined to not be feasible at this time since it would be too steep to be ADA compliant. 4.3. Water quality monitoring for Karth Lake for 2025. Gary Gerding 4.3.1. Background: The KLIDB has participated in the Citizen-Assisted Monitoring Program (CAMP) with the Metropolitan Council by coordinating volunteer sampling of Karth Lake’s water quality since 2006. 4.3.2. Action: No updates at this time. Generally, we receive results from Rice Creek Watershed in time for our April meeting. 4.4. Discuss garden maintenance for the garden bed within Cummings Park as well as the rain garden on Nursery Hill Lane. 4.4.1. Background: The Art Larson memorial garden in Cummings Park needs cleanup as does the rain garden on Nursery Hill Lane. 4.4.2. Action: • At our previous meeting we recommended that the memorial garden be left to go wild with the native plants that are there and with the city providing the same maintenance they do to other areas in Cummings Park. • Joel looked at the rain garden in the middle of Nursery Hill Lane has all the classic rain garden plants and functions very well. There are a few weeds but for the most part it is a very attractive rain garden and effective rain garden. Joel has talked to neighbors about doing some weed removal. The city went through and cut down the plants late in the Fall in preparation for the next year. • The city has hired a new Parks and Rec manager and one of her duties is to manage the Rain Gardens so there is a start on having a planned program for the Rain Gardens in the city. 5. NEW BUSINESS 5.1. Planning process for next election of KLID Board Members and Officers whose terms have expired. 5.1.1. Background: The terms for two board positions expire in 2026: those for Linda Hansohn and Kent Stennes. In addition, one open position currently exists. The process for announcing the April 2026 election and requesting candidates to fill open positions involves the drafting of a letter to Karth Lake Improvement District members (which are, by definition, Karth Lake shoreline property owners). The City of Arden Hills then sends that letter to members by regular mail. 5.1.2. Action: A subcommittee made up of Joel, Renee and Andrew will write the communications that will be sent to the property owners describing the work that was done in 2025 as well as the upcoming election. 6. NEXT MEETING: Tuesday April 14, 2026 at 6:30 PM at City Hall. 7. ADJOURN Resolution of Karth Lake Improvement District Board Resolved on April 7, 2026 at KLID Board Meeting Now therefore be it resolved by the Karth Lake Improvement District Board that the following amends the Resolution of Karth Lake Improvement District Board dated January 13, 2026: 1. The City implement the pump improvements as proposed by the City Engineer and described as “Alternative 3” within the 2026 PMP Street & Utility Improvements project construction plans for an as-bid cost of $225,000. 2. The residents on the lake pay for 50% of the as-bid construction costs through a levy proportional to each property’s tax value over the tax years of 2027, 2028 & 2029. Providing: 1. The City will finance the initial costs so the pump improvements can be constructed as part of the 2026 PMP. 2. Any Rice Creek Watershed District grant funding is used to lower the cost-share amount between the City and KLID. 3. The City will cover any indirect costs and overhead costs related to the pump improvements. 4. The City will continue to cover the cost of operating the pump, installing it in the spring, removing it in the fall and storing it. 5. Costs related to the failing retaining wall are not to be included in the proposed KLID levy amount as referenced in the Resolution of Karth Lake Improvement District dated January 15, 2020.

The ATRA Key features a structurally reinforced handle and frictional barbs to enhance interlock with the GEOWEB surface texture, providing protection against the three primary modes of mechanical junction failure: shearing, splitting, and peeling. The ATRA Key is inserted through aligned I-slots of two adjoining GEOWEB sections and turned 90 degrees to lock the key in position. If removal is required, turn the ATRA Key 90 degrees from the locked position and remove the ATRA Key from the I-slots.

The ATRA® Tendon Clip is used to transfer driving gravitational forces from the GEOWEB® cell walls to the tendon and crest anchorage system. The device includes a structurally reinforced post and locking member with frictional barbs for improved interlock with GEOWEB® surface texture. The ATRA® Tendon Clip is inserted through the I-slot and turned 90 degrees to lock the device into place. Once locked into place, the ATRA® Tendon Clip is positioned to facilitate the intended load transfer effect. If removal is required, the ATRA® Tendon Clip may be unlocked and removed by turning 90 degrees from the locked position and removing the device from the I-slots. When the ATRA Tendon Clip load transfer devices are connected, the complete tendoned GEOWEB system may be efficiently pre-assembled at the crest before expanding the sections down the slope.
