Published Seattle Times May 3, 2022, and May 10, 2022 Published Daily Journal of Commerce May 5, 2022, and May 12, 2022 REQUEST FOR PROPOSALS st S 131 Place Drainage Improvements Project PROFESSIONAL ENGINEERING AND DESIGN SERVICES PROJECT DESCRIPTION: st The purpose of this project is to address localized flooding along S. 131 Place and st further, to improve stream conditions in the Southgate Creek basin. S. 131 Place is a low volume roadway positioned in a lowland area in the Riverton neighborhood of Tukwila that primarily services local commercial and industrial land uses. During high st flow events, Southgate Creek overtops its bank and flows over and across S.131 Place st and onto private properties on the opposite side of 131 Place, resulting in flooding, debris deposition, and minor roadway and property damage. To reduce the frequency and impacts of these flood events, the mainstem streambed is periodically dredged by the City in compliance with a limited Hydraulic Project Approval (HPA) from the WA Department of Fish and Wildlife. City staff have identified the following factors that st potentially contribute to flooding along S. 131 Place and other stream impairments in Southgate Creek: lack of buffer between road and stream roadway elevation undersized culvert beneath 131st Place (with a reverse profile grade) adjacent land development reach-altering alignment interventions for stormwater control flow diversion st increased rates of sediment deposition along S. 131 Place due to low flow upstream sources of sediment include channel incision, a localized land slide in the middle reach, and choked sediment traps in multiple reaches CONSULTANT SCOPE related components with overlapping or simultaneous timelines. Part A will be to develop, to a 90%-level or greater, a permitted design for a fish-passable culvert st beneath S. 131 Pl and associated stream and/or roadway improvements that will improve stream flow, alleviate flooding, and eliminate barriers to fish migration. Part B will entail an assessment and analysis of the Southgate Creek basin for the purpose of identifying future surface water improvement projects that will reduce downstream flooding, eliminate the need for regulated dredging activities, improve water quality, reduce undesirable erosion, and improve stream flow alignments and/or conditions to benefit fish passage and habitat. Improvement project(s) that directly reduce flooding at st 131 Place may be carried forward with Part A of the project, depending on budget and other considerations. Property acquisition may be considered for both parts of the project, if feasible and if justified, to meet project goals. The City has two documents that are available upon request that provide additional context to the project.
