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.

Join us for our first two meetings in September!

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.

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.
