Healthy Septic and Water

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.
