Stormwater engineering team helps Contra Costa Clean Water Program implement NPDES permit
Summary
- The Contra Costa Clean Water Program relied on us to respond to new provisions of its stormwater permitting program.
- With hydrological expertise and listening skills, we crafted plans that met the needs of 20+ co-permittee jurisdictions.
- We guided green infrastructure retrofit approaches, training programs, and more to keep the program in compliance.
Client challenge
The Contra Costa Clean Water Program (CCCWP) works to prevent stormwater pollution in Northern California’s Contra Costa County, home to more than 1.1 million residents.
Its 20+ co-permittee jurisdictions relied on our help to understand and comply with new provisions of the National Pollutant Discharge Elimination System (NPDES) San Francisco Bay Area Municipal Regional Permit (MRP) 3.0 stormwater permitting program. The CCCWP trusts our guidance because we listen to the needs of all co-permittees and then balance those needs while satisfying regulatory requirements.
Our approach
Working quickly to understand changes to the MRP while knowledge of the previous program was still fresh, our team built off experience designing and installing green infrastructure, such as green streets, across the region to develop related MRP 3.0 provision C.3 guidance and green infrastructure retrofit approaches to the CCCWP. We also evaluated and recommended approaches to hydromodification management compliance.
We drew on deep hydrology experience: Our team included scientists who worked on Contra Costa’s original water management program as well as those with engineering design experience from other green infrastructure projects — which filter and absorb stormwater — in Northern California. And our nationwide presence enabled us to draw in the right technical leads for the job, regardless of location.
CCCWP continues to rely on us to develop guidance documentation, provide green infrastructure design concepts, conduct its annual trainings and consult as needed on all aspects of the program.
Value delivered
- Developed guidance and green infrastructure retrofit approaches for new stormwater permitting program provisions
- Built a strong partnership that continues guiding CCCWP’s 20+ co-permittee jurisdictions on program compliance
- Created educational materials and ran trainings to communicate program requirements for co-permittees and external project applicants
