Stormwater Facilities and Maintenance
Maintaining your Stormwater Runoff Water Quality Facility
All new construction and redevelopment sites in the SEMSWA service area are required to provide stormwater controls to address higher runoff volumes and pollutant loads associated with an increase in impervious surfaces, such as rooftops and parking lots, once the project is completed. These stormwater controls are here referred to as Stormwater Quality Facilities.
As part of this requirement, these stormwater control facilities must also be properly maintained and routinely inspected to ensure they continue to function well and are not forgotten. Additional signage near the stormwater control facility may serve as a helpful reminder to others.
Unsure if you have a stormwater quality facility on your site? Please see our Maintaining Your Stormwater Feature page.
