The Riparian Restoration Program (RRP) provides the SR-167 Completion Project with an alternative to conventional stormwater detention system by capitalizing on the adverse site conditions. The proposed highway corridor crosses the FEMA identified 100-year floodplain, cuts through wetlands, and requires relocating several watercourses. With these significant site constraints, it would be almost impossible to provide the conventional storage needed to meet the flow control standards of the Western Washington State NPDES Permit Program. The Project development team developed the RRP to eliminate the need for dedicated storage facilities by restoring the relocated creeks, reconnecting them to the floodplains and adjacent wetlands, providing improved connectivity for ESA listed salmon between the Puget Sound and the upper reaches of Hylebos Creek, and reducing the extent and severity of flooding in the area. The SR-167 Completion Project was recently funded and the design process restarted. The RRP will be completed in an early phase of construction so that the system will be online and functioning as the construction of the highway is completed. As part of the design process WSDOT looked at accommodating sea level rise and resilience to increased precipitation intensity. The RRP concept caught the attention of our FHWA partners and WSOT was asked to participate in a pilot project with the Netherlands to test the FHWA and the European ROADAPT systems for assessing vulnerability and adaptation to climate change. This pilot project includes face-to-face meetings with our Dutch partners in The Netherlands and included a Dutch visit to the SR-167 corridor in October 2018. Of particular interest, is the use of restored or naturalized channels as an adaptation strategy to increase the resilience of the highway drainage system under extreme weather conditions. The presentation will provide a history of the RRP, a summary of our climate change pilot project as it relates to the SR-167 project and the RRP, and the current design of the RRP that is to be constructed beginning in 2020.
