Lower Taylor Creek Culvert Replacement and Habitat Improvement Project

Location: Seattle, WA

OCI performed the Lower Taylor Creek analysis of alternatives for Seattle Public Utilities to improve fish passage, alleviate flooding, and stabilize the stream system. The project began with OCI leading a brainstorming session where OCI, Seattle Public Utilities, and Project Stakeholders identified alternatives and assessed the triple bottom line to identify alternatives for further analysis. Further analysis included conceptual design, cost estimates, channel hydrology and capacity, habitat restoration, fish passage design, stream and floodplain restoration, identifying sources of flooding, and improved sediment transport at the mouth. This project is the #1 Seattle Public Utilities fish passage barrier on the city-wide prioritized list. OCI completed the assessment and alternative analysis of this fast track project within a four month time period.
