Fourth on the Plateau

Date and Time
Saturday, July 4, 2020
6:00 PM to 10:30 PM
This event has been canceled.

In order to protect the community and mitigate the risks associated with COVID-19, the City Council voted to cancel all City of Sammamish events through the end of August. This was not a decision that was made lightly, and the City has the deepest regret that the community will not be able to come together to celebrate in-person during this challenging time. However, the safety of our residents is of the utmost importance. The unknown trajectory of the pandemic and the impossibility of maintaining safe social distancing at these popular events weighed heavily in the decision. We recognize the importance of our summer events in bringing the community together to enjoy the wonderful atmosphere at our Parks, and we look forward to a time when we can all celebrate Sammamish together!
