The Delridge Multimodal Improvements Project, a 4-mile corridor within Delridge Way SW from the West Seattle Bridge to Roxbury Street SW, will install 26 enhanced RapidRide Stations, improve bike and pedestrian connections to transit, and provide greenway connections. Serving as Drainage Design Lead, RKI is responsible for code compliance, hydrologic/hydraulic analysis, basis of design and design coordination for final design of stormwater management facilities.

As part of its Plan to Protect Seattle’s Waterways, SPU committed to constructing green and/or gray infrastructure that will bring the Vine basin into compliance with Combined Sewer Overflow (CSO) regulatory requirements by the end of 2025. Serving as GSI Lead, RKI helped SPU develop and evaluate GSI options and select the preferred option to be advanced to final design and construction.

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.
