The new “C.3” provisions are separate from—and in addition to—requirements for erosion and sediment control and pollution prevention measures during the construction phase of the project. In addition, project applicants must prepare plans and execute operations and maintenance agreements to insure that the stormwater treatment devices are maintained in perpetuity.
Through the Contra Costa Clean Water Program, local governments have created a Stormwater C.3 Guidebook available here to help developers comply with the new C.3. requirements. Please visit the Contra Costa Clean Water Program website for a more detailed and thorough explanation of all Stormwater regulations: http://www.cccleanwater.org/c3.html
The information contained on this website will help you successfully plan for “C.3” compliance for your project.
