BUILDING SOMETHING TOGETHER

There's a place for everyone.

Whether you're a resident, a trained volunteer, a neighborhood organizer or a local organization, your experience can help shape a more resilient Mercer Island.

Mercer Island Prepares is in its planning phase. Public sign-ups and a partner interest form will be added when the program's coordinating organization and data-privacy process are approved.

Existing teams come first

Mercer Island already has City-established volunteer response teams, including CERT Training, Communications, Shelter, Water Distribution and Senior Care. Contact the City for official volunteer onboarding and credentialing.
