Due to the excessive heat warning in effect from 2pm today (6/25) to 9pm Monday (6/28), Puget Soundkeeper Alliance is cancelling all events for this Saturday’s Seattle Summer Cleanup Series at UW Arboretum & Lake Union. Please check back for expanded programming later in the coming weeks as we look to reschedule these vital community projects. Please stay safe this weekend; we look forward to seeing you on the waterfront soon.
