WAUKESHA, Wis. (CBS 58) -- A daily permit will cost $7 per vehicle at Retzer Nature Center in 2027, and an annual membership will cost $40 for most people and $20 for seniors, Waukesha County announced on Wednesday, Nov. 11.

The annual membership will also cover the county's nine parks.

The county says program registrations, rentals, permits, sponsorships, tax levy support and donations don't cover the full cost of running the grounds and learning center. It says Retzer has been the exception to the entry fees charged across the county park system, and the new fee will match the system's funding model.

"We did not make this decision lightly," Retzer Nature Center supervisor Stacy Yearling is quoted as saying.

Memberships for 2027 go on sale Nov. 27. More information can be found by clicking here.
