As an alternative to more traditional stormwater management approaches which rely on above ground detention basins, Sigma designed an innovative stormwater management system for an approximate 1.23-acre commercial development in Oak Creek, Wisconsin. The system utilizes previous concrete pavement and an underlying stone detention bed for management of stormwater at the site. The system results in zero discharge of stormwater from the site and eliminated the need for additional land to accommodate traditional above ground stormwater detention basins.
