The Port of Seattle Commission considered Resolution No. 3821 in April 2024, which adopts a Land Stewardship Plan and Tree Replacement Standards for Seattle-Tacoma International Airport (SEA). The plan sets goals for balancing airport operations and development with environmental responsibilities, including restoring forests, protecting wetlands, and replacing removed trees using a credit-based system requiring four stewardship credits per tree removed. No funding was requested at the time of adoption, as the resolution focuses on establishing policy guidance for how SEA manages its natural resources during future construction and operational activities.Open full document
