2019 STORMWATER MANAGEMENT MANUAL FOR EASTERN WASHINGTON UPDATE

Ecology, working with a Steering Committee of Eastern Washington Phase II National Pollutant Discharge Elimination System (NPDES) permittees, completed a 2019 update of the Stormwater Management Manual for Eastern Washington. RKI helped incorporate the latest advances in design, construction, and maintenance techniques for conventional and Low Impact Development stormwater BMPs into the manual and provided team facilitation and public outreach, helping to gather and incorporate necessary inputs for successful use of the manual.

2019 EAST BREMERTON & EAST PORT ORCHARD STORMWATER RETROFIT PLAN

Kitsap County Public Works (KCPW) developed a stormwater retrofit plan for East Bremerton and East Port Orchard to identify, prioritize and construct stormwater retrofit projects that address water quality and drainage problems. Both Green Stormwater Solutions and conventional stormwater techniques are used. The end result is a suite of management planning tools, including a prioritized list of projects and conceptual designs to support KCPW’s Capital Facility Plan and assist with obtaining grant funding for final design and construction of priority projects.

SPU BALLARD NATURAL DRAINAGE SYSTEMS

SPU estimates a Combined Sewer Overflow (CSO) control volume of approximately 6 million gallons is needed to meet NDPES CSO control regulations for two uncontrolled basins in the Ballard neighborhood. While at a previous firm, Robin served as Project Manager and Lead Engineer through Options Analysis and final construction design of 17 blocks of residential roadway GSI for CSO control. Following construction in 2016, RKI was retained to develop the project-specific standard operating procedures and operation and maintenance manual. This project won the inaugural 2017 Pacific Northwest Clean Water Association Innovative Stormwater Project award.
