About Park Hill Detention
This new stormwater management system will reduce flooding in the Park Hill area by installing new stormwater pipes along 39th Avenue from Dahlia Street to Grape Street, and near Dahlia Street and Smith Road. The project will also construct a detention area in the northeast corner of Park Hill Golf Course to more effectively hold and slow stormwater that flows through the area.
Construction crews are working near Dahlia Street at Smith Road and 39th Avenue, working their way east along 39th Avenue to Grape Street. Initial work involves the removal of asphalt and relocating several existing underground utility pipes.
Construction began in November 2018 and is planned for completion in June 2020.
