When it rains, stormwater washes over the loose soil on a construction site, along with various materials and products being stored outside.

As stormwater flows over the site, it can pick up pollutants like sediment, debris, and chemicals from that loose soil and transport them to nearby stormdrains or directly to the Boise River. Planning and Development Services works with construction site operators to make sure they have the proper stormwater controls in place so that construction projects can proceed in a way that protects our community’s water and the surrounding environment.

Boise's Erosion and Sediment Control Program

Boise's Erosion and Sediment Control (ESC) Program reduces or eliminates sediment discharge and pollutants into streets and the storm water system.

The program covers all construction activity and all construction sites, regardless of size or ownership. The ordinance applies to commercial and industrial operations, residential practices, and construction site operations.

Visit Planning and Development Services to learn more about the ESC program.

The City of Boise requires each construction project to have an individual in charge of the site's erosion and sediment control program. The individual must have direct, day-to-day control over the site's construction activities, and be trained and certified by the City of Boise as either a Responsible Person or Plan Designer.

There are many opportunities and classes available, offered December through June.
