Welcome to the Alliance for a Healthy South Sound

Working together to protect and restore South Puget Sound.

The Alliance for a Healthy South Sound (AHSS) exists to support coordinated and collaborative decision-making aimed at restoring and protecting the ecological and socio-economic health of South Puget Sound.

The Alliance was formed in 2010 as a collaboration between Thurston, Mason, and Pierce Counties, the Squaxin Island Tribe, and the Nisqually Tribe, and provides a forum for those jurisdictions to work together on issues of mutual interest and projects that benefit the South Sound. The Alliance also is recognized by the Puget Sound Partnership Leadership Council as the Local Integrating Organization for South Puget Sound and given the responsibility to coordinate development of local Puget Sound recovery actions for the Puget Sound Action Agenda.
