Public Meeting 2
Wednesday, September 28
6:00 - 8:00 p.m.
VFW Post 2995
4330 148th Ave NE Redmond, WA 98052

Thank you to those that attended our September 14 meeting or shared their ideas online. We heard valuable feedback on what the City should consider when evaluating different projects that would divert or store stormwater to protect and restore Tosh Creek's Tributary B. We also heard some new ideas for projects to consider.

At Public Meeting 2 we will give an update on the suggestions we heard and look in greater detail at the options that are feasible and how they are being evaluated.

During Public Meeting 2 we will have small group conversations to discuss:

  • The feasible projects that would reduce stormwater flows into Tributary B, and possible combinations of projects that would reduce flows enough to improve the health of Tosh Creek.
  • How the projects have been evaluated based on the City's evaluation factors and public input received to date.
Small group conversations will be an opportunity to:
  • Have detailed discussions with technical staff and ask questions about all the feasible projects.
  • Provide direct feedback to the city on how we have evaluated the feasible projects.
Your input during small group sessions will be documented and used to further narrow options for restoration of Tosh Creek's Tributary B.

We hope to see you there!

Project Update – 8/24/2016

During and after the Tosh Creek Watershed Restoration public meeting and ice cream social in June we heard concerns from the community about the 159th Avenue Vault Project’s proposed location, including potential construction impacts and the proposal to build a neighborhood park on top of the vault.

The 159th Avenue Vault Project design is paused for more community input. We plan to host a series of public meetings and working sessions with the community, this fall. We will gather input from you as we evaluate various locations for stormwater storage near Tributary B and work to make a final recommendation.

Project Update - Tosh Creek7/28/2016

The City has reviewed the responses to the June 13th public meeting and has had follow up meetings with residents from Tamarack Lane. Within those communications was concern about the large temporary and permanent project impacts and a request for more information about the Tosh Creek Restoration Program. Specifically, the group is seeking response to the following questions:

You can find responses to those questions on the left side of this website. The City is working on a community engagement program that will include a series of meetings where you can meet with City staff to learn more about these topics and provide your input as the City selects the preferred path forward.

In the meantime, the proposed construction of the 159th Vault project is on hold and will not occur in 2017. The City is reevaluating alternatives for projects near Tributary B with the goal of determining the path forward later this year.

Project Update - 7/14/2016

The Tosh Creek online open house is now closed!

The design team has completed preliminary engineering for the six projects shown in the project map.These projects are proposed for construction from 2016-2022 as shown on the project schedule.

In May 2016, we distributed a project newsletter to residents and businesses within the watershed. Here are a few project updates that were included in the newsletter:

  • 159th Avenue Vault Project   
    We are reducing costs and construction impacts by moving the proposed vault from the street onto three adjacent properties. The City owns one of these properties and is negotiating the acquisition of the other two with the property owners.

  • 50th Way Flood Reduction Project   
    We have reached final design and are conducting outreach for the project. We will advertise the project to contractors in June and construction will start this summer.
