Drainage & Stormwater Quality

Our stormwater quality and drainage project work includes regional flow control and water quality facilities, basin studies, facilities needs assessment and corrective actions plans, facilities inventories, operations and maintenance manuals, industrial site developments, residential drainage designs, roadway and parking lot drainage designs, permitting assistance, and regulatory compliance. Our Low Impact Development techniques include the design of rain gardens, dispersion trenches and bioretention facilities, permeable pavement, and water harvesting.

Flood Mitigation

DCG managed preliminary engineering, design and construction management of four creek culvert replacements through the Lake Forest Park Town Center and crossing SR 522, an area that had experienced severe flooding in past years.  Existing water mains needed to be re-routed and custom thrust restraint systems designed to accommodate the culvert replacement. Stream improvements and fish enhancements were also made. DCG guided the project through a rigorous permitting schedule including submittals to six different regulatory agencies. This project was awarded APWA's 2015 Environmental Project of the Year.

Madison Valley Diversion and Stormwater Facilities Phases II and III

Design and construction phase support for local stormwater drainage, collection, and conveyance to a 2.1 million gallon storage facility. Services also included road restoration design and SDOT Street Improvement Permit (SIP) process.

On-Call Drainage Services

Design phase engineering services and construction phase support for more than 30 drainage related projects that included a variety of stormwater collection/conveyance systems and outfalls to Puget Sound.

Dallas Ave S Drainage

Stormwater improvements related to the T-117 Adjacent Streets cleanup project provide a high standard of water quality treatment, including bioretention areas with specialized treatment media and Filterra® Bioretention Systems.
