GREENDALE, Wis. (CBS 58) -- Trimborn Farm, Milwaukee County's only historic park, faces about $1 million in deferred maintenance, and county leaders are looking for a public-private partnership to keep it running.

"What we don't want to see, I don't think this community wants to see this turn into some sort of development. We are on the national historic landmark and so we want to keep it that way," said Milwaukee County Supervisor Kathleen Vincent.

Several people have reached out to the county about the farm, and leaders say a local resident has contacted them about a collaborative effort.

The farm has been around since the 1850s and serves as an educational center and event space.
