Board backs pilot to convert underused turf to native prairie habitat

The Board of Public Works on May 5 informally recommended proceeding with a pilot to convert select underused city-owned turf areas into native prairie habitat and pollinator plantings.

The presenter described the proposal as a phased pilot aimed at reducing long-term mowing and maintenance costs while improving stormwater infiltration, soil health and habitat for pollinators. “The objective is to reduce long term maintenance costs, improve environmental sustainability, and enhance ecological function across public properties and the park system,” the presenter said.

Staff told the board the city maintains large amounts of mowed turf across parks, rights-of-way and open spaces that receive minimal recreational use. The presenter said conversions typically require a two-to-four year establishment period with active weed control and periodic mowing during establishment, and that initial site preparation and seeding costs are higher than standard turf maintenance. The presenter noted opportunities for grants or partnerships “through the DNR, other conservation groups, or local partnerships.”

Board members asked about site suitability and potential unintended effects. One member asked whether herbicide use or converting areas near stormwater retention ponds could affect water systems; the presenter replied that options include herbicide application or temporary agricultural cropping as part of site preparation, and that consultants recommended short-term farming in some cases to prepare seed beds. Another member raised concerns about deer activity and visibility near high-traffic park edges, urging careful site selection and public education to avoid areas that could be misinterpreted as neglected land.

The presenter said the staff recommendation was to select a pilot site — staff noted a nearly five-acre parcel near Wildwood Park as a possible demonstration site — develop cost estimates, and create an establishment plan with signage and outreach to explain the purpose to residents. After discussion, a board member moved to support the pilot and authorize staff to identify locations and pursue funding; the motion was seconded and carried by voice vote.

The board’s action was advisory and set direction for staff work; the motion authorized staff to proceed with site selection, cost estimates and outreach rather than approving a planting contract or specific site at this meeting. Next steps include staff site assessments, cost estimates and outreach to potential partners and funders.
