• 7/21/22 Field trip to top 2 sites

  Representatives from Friends of the Farms, Squamish Tribe, Bainbridge Island Land Trust, and the Bainbridge Island Watershed Council joined city staff to look at the top 2 scoring sites in the field and provide design input.

• 12/15/21 Project Scoring Meeting
  Staff from the City and Herrera Environmental led the steering committee through a "story map" highlighting 13 conceptual project ideas that met feasibility requirements. Next the committee reviewed a draft scoring matrix to help guide the project towards two top projects. These top projects will move on to the next phase and begin the design process.

• 10/14/21 Initial Site Review
  Staff from the City and Herrera Environmental Consultants visited over 20 sites in the watershed to review the feasibility of conceptual stormwater retrofit ideas. The sites will be further reviewed for infiltration potential, utility conflicts and contributing basin size to establish a ranked list of projects.

• 8/21/21 Walk the Watershed: Learn about Manzanita watershed planning
  City staff will be leading a guided walk on a 2-mile route through the hills and valleys of Manzanita watershed on Saturday, August 21 at 10 AM in support of the Watershed Assessment of Manzanita. This walk will showcase some of the recent successes while highlighting future challenges facing the aquatic habitat of Manzanita Creek. We will visit an inactive gravel mine, wetlands, fish passable culverts and stormwater ponds along the way. Participants will learn about recent legislation regarding streamflow restoration and how the city is using Federal grant funds that address a disrupted hydrologic cycle. The walk is mainly on quiet roads and trails but also crosses a busy road and should last about 2 hours. Participants should dress appropriately and will be asked to fill out a waiver prior to participating. Due to social distancing needs and challenging road crossings, the tour will be capped at 10 participants. Please RSVP for more details by emailing Christian Berg at cberg@bainbridgewa.gov.

• 5/26/21 Steering Committee
