City facilities, including City Hall, Municipal Court, and the Police Station, will remain closed to the public through at least April 8 pursuant to Gov. Jay Inslee’s “Stay Home, Stay Healthy” order.

Please see the Building Department Update for more information about what activities can occur under the order and how it is impacting other essential facilities such as parks and schools on the City’s COVID page.
