Plans to build an Olympics-level indoor sports facility on the north bank of the Spokane River got a little closer to reality this week, as a report showed that the facility would generate four dollars in economic impact for every dollar spent to build and operate the complex during its first five years. The 185,000-square foot “sportsplex” is planned to sit on five acres of land just east of the Spokane Veterans Memorial Arena, and would house a 200-meter hydraulic banked indoor track, the same type used in the Olympics. The track would be just one of 10 in the country.
