A youth sports complex featuring dozens of fields, an indoor training facility, retail space and a hotel is being proposed for a 150-acre site in Big Bend.

The project, known as the Breck Athletic Complex, would be built in multiple phases with a total estimated cost of between $175 million and $225 million. The first phase would focus on sports facilities and fields, with later phases adding retail, dining and lodging.

The project site is located southeast of Highway 164 and Town Line Road. The property is currently owned by an affiliate of Waukesha-based Weldall Manufacturing, according to Waukesha County records.

Eric Weishaar, who founded Wauwatosa-based Breckenridge Landscape in 2009, is leading the project. Weishaar is working with Minnesota-based design firm ISG, which also has an office in Brookfield.

Plans call for an expansive athletic campus featuring six turf baseball fields, a championship baseball field with seating and a plaza, seven full-size soccer fields, three futsal fields and four lacrosse fields. A roughly 155,000-square-foot indoor turf facility would allow for year-round baseball, soccer and lacrosse training, as well.

Stiks Academy & Sports Training, currently located in the Village of Waukesha, would also move to the complex, according to Weishaar.

“Designed to be more than a traditional sports complex, the Breck Athletic Complex is envisioned as a destination where local residents, tenants, customers, and the general public are drawn to experience all that it offers,” the development team said in its proposal.

Supporting amenities would include concessions, restrooms, playgrounds, fitness trails and landscaped plazas.

Future phases of the development could include more than 50,000 square feet of retail space, potentially housing restaurants, a craft bar or brewery, and a banquet hall, as well as a 60-room hotel.

“It’s going to be the first of its kind in the area,” Weishaar said at a November Plan Commission meeting. “It’s going to be the biggest, probably, in the state. We’re going to be attracting not only the local clubs and teams, but we’re going to be attracting a lot of out of state clubs and teams.”

When the plan first became public in November before the village’s Plan Commission, the development team initially sought a conditional-use permit. That request has been dropped, and now the developer is requesting that the property be rezoned for commercial with a planned-unit overlay district.

The project site is located about 5 miles south of downtown Waukesha. The interchange with I-43 and Highway 164 has remained largely undeveloped, with McDonald’s, Subway, Kwik Trip and Stein’s Garden & Home being the primary commercial tenants.

In November, Weishaar said the hope was to begin construction on the first fields this spring.
