Four City ILA

The cities of Burien, Des Moines, and SeaTac have entered into a formal agreement to coordinate their review of, and potential legal challenges to, the Port of Seattle's Sustainable Airport Master Plan, which could significantly impact surrounding communities over the next 20 years. The three cities agreed to share costs proportionally based on population, jointly hire environmental consultants and legal counsel, and issue unified comment letters during the NEPA and SEPA environmental review processes. Key provisions require unanimous agreement to file a joint appeal and a two-city majority to continue litigation at each subsequent stage.
