Project Description

Location: 21815 SR 9 SE Woodinville, WA 98072

Maltby Area Park (aka Carousel Ranch) is a 65.23-acre future park site. Cutthroat Creek meanders from the northeast across the woodland and flows through a culvert under SR 9 to the west. There are several existing structures, wetlands and ponds. Snohomish County Parks and Recreation is in the process of re-designing the park set forth by the 2005 Brightwater Mitigation Agreement and other program elements through input from public meetings and an Ad Hoc Committee comprised of an equitable number of neighbors, stakeholder/user groups and county park staff.


The site was acquired on October 30, 2015, through funding from the 2005 Brightwater Mitigation Agreement between King County and Snohomish County for the construction and siting of the Brightwater Treatment Plant in Snohomish County.

“This project will provide primarily active recreation facilities for the broad community surrounding the treatment plant site. The community and potential user groups will be included in the design process that will lead by Snohomish County. Multiple locations are currently being considered. This funding is for acquisition and development of this active recreation facility,” from the 2005 Brightwater Settlement Agreement.


Two fields will be constructed and striped to accommodate multiple sports with lighting to allow night games to be played. The fields will be striped for the following sports:

  • Soccer
  • Baseball and softball
  • Football
  • Lacrosse
  • Rugby

There will be an off-leash dog area, walking trails, maintenance facility, portable restrooms, ample parking and a new entry design on SR 9.

Current Status

Updated 2/10/23

  • Snohomish County Parks Division submitted local permitting plans to Snohomish County Planning and Development Services on 4/1/2022 for initial review. After the initial review, we received comments and started to respond to the permitting agencies. During this process, the county received updated budget costs from the consultant. Construction costs have risen significantly during the past few years and the new estimated cost required a redesign of the project. The new design is underway and will reduce the total number of fields from four to two, the parking areas will be reduced by half, and walking trail and bridge structures will potentially be removed. The off-leash dog area is being relocated to where the upper two fields are being removed. The county has asked the consultant to have all plans updated and prepared to have this project publicly bid spring of 2023 and start construction summer of 2023.
  • Army Corps of Engineers Federal permits were forwarded to NOAA Fisheries for their review on 12/20/21. NOAA reviewed our application and sent the county additional questions in September 2022. The county and consulting team replied to NOAA and are awaiting their final response.

  • As part of the permitting process, Tribal Nations were consulted. They have reviewed the mitigation plans and are satisfied that the mitigation will be of positive benefit to salmon production.

  • In collaboration with DCNR and the SWM Division, improvements were made to Cutthroat Creek for water quality and fish habitat.
  • The project is currently in the redesign phase.
