Under a partnership with the Water Resources Commissioner and the City of Ann Arbor, Pioneer High School will be the site of a new underground water treatment system that will clean pollutants from water on its way through Allen Creek to the Huron River. Construction will begin this December in the lawn near Stadium Boulevard and South Main Street. The project involves digging down to the storm sewer, installing the system, replacing the soil and re‐seeding. The front lawn area shown in the attached graphic will be completely enclosed by an eight foot fence. Although most construction will conclude by August 2010, an area the size of a soccer field will be covered with stone for the first winter and then re‐seeded in spring 2011.
