Tonight, residents can weigh in on adding a sports complex to Westfield.

The Advisory Plan Commission will hold a public hearing on amending the city’s comprehensive plan to include a sports complex, which likely will be more than 200 acres. The Advisory Plan Commission will vote on whether to add the complex to the plan after the hearing.

If the complex is added, it would be the second of two large developments added to the comprehensive plan this year.

Westfield amended its comprehensive plan in April to include extensive downtown redevelopment.

Westfield’s Sports Complex Commission, which decided the complex was viable, has not determined the details of the complex. Last week, the commission discussed including 74 fields and courts for at least 10 sports, including basketball, football, rugby, lacrosse and tennis. The commission is considering three locations for the complex: Towne Road between 146th and 161st streets, and areas on the northwest and northeast corners of the intersection of U.S. 31 and Ind. 32, said Kevin Teder, the commission’s leader.

The group hopes to have a rendering by October.

Westfield announced the project in April as a strategy to become the “Family Sports Capital of America.”

The public hearing will be at 7 p.m. today at City Hall, 130 Penn Street.
