While the French will celebrate Bastille Day on July 14, Portland residents on the same day will be able to greet another unusually high tide with the “King Tide BYO Chair Party.”

Artists, actors and residents will mark the late-night, early-morning occasion of the “king tide” — a high tide rising above the flood marker of 11.6 feet — with street theatre, street sculpture, outdoor cinema featuring flood-movie trailers, puppetry and general bonhomie at one of Portland’s most vulnerable areas for tidal flooding.
