The Edmonds City Council at its Tuesday, April 28 business meeting will consider a $383,456 amendment to consultant contract for the second phase of a flow reduction study in the Perrinville drainage basin.
The city has been working for years to develop strategies to control flooding on Perrinville Creek between Talbot Road and Puget Sound. A flow reduction study in 2015 resulted in a list of recommendations, from drainage improvements to a municipal raingarden program.
The City of Lynnwood, which sends stormwater runoff to the basin, is partnering with the Edmonds on the project. Both cities were awarded a $469,200 state Department of Ecology grant toward this effort to analyze the problem, which requires $82,800 in local matching funds from Edmonds and Lynnwood. The grant and matching funds are split bet
According to the staff agenda memo regarding this item, the grant and matching funds are split between the two cities. The amendment to the professional services agreement is $383,456 and includes a $20,455 management reserve, the memo states.
“In 2024, Edmonds and Lynnwood entered into an interlocal agreement and contracted Herrera Environmental Consultants to provide design services for the study update, the memo says. “Phase 1 of the study update involved a review of the recommended projects and planning level design and estimating work of new projects. Projects were rated based on criteria including impact on flows, constructability and cost effectiveness.”
The contract’s second phase “will include a more in-depth analysis, including geotechnical investigations for the sites that include mitigation via infiltration, for the 10 highest-scoring flow reduction projects from first phase of the study update. Once the analysis is completed, the project rankings will be reassessed and the consultant will provide conceptual design for the six highest-scoring sites.”
Other items on the council agenda include:
- 2025 Prosecutor’s Office Annual Report
- 2025 Public Defender’s Office Annual Report
The council will also hear an update from Police Chief Loi Dawkins on the public safety sales tax.
The meeting will begin at 6 p.m. in the council chambers, Public Safety Complex, 250 5th Ave. N., Edmonds. You can also access the meeting remotely at this Zoom link. Or listen by phone at +1 253 215 8782. The meeting ID is 957 9848 4261.
