Healthy Septic and Water

Updated: 1 day ago

*** Update August 11, 2026 ***


The Marine Recovery Area Program Update proposal to the King County Board of Health will be delayed until 2027. We have heard strong support for updating the Marine Recovery Area, and we have also heard that more work is needed before our proposal is finalized.


Thank you to the Vashon-Maury Island community members who have engaged in thoughtful conversations about how to best ensure that septic systems on the island are maintained so that water quality and public health are protected.


Over the next months, Public Health will work with partners and community members to address topics necessary to finalize the proposal and successfully implement the program, including:

  • Strategies to reduce costs of inspections,

  • Service provider availability and training, and

  • Effective implementation of risk-based septic inspection model.

Shoreline homeowners with septic: view this presentation from Public Health's June 2026 Vashon-Maury Island (VMI) Community Meeting which covers a proposal to update the Marine Recovery Area for Vashon and Maury Islands. Important updates to shoreline septic monitoring requirements are described.


How have Vashon-Maury residents already improved water quality through septic monitoring and upgrades? Since 2016, over 400 new acres of Vashon-Maury shoreline have been opened for shellfish harvesting. See kingcounty.gov/MRA for details.
