2026-07-15Sea-Tac Communities Plan: Water quality, airport, and community development
The Sea-Tac Communities Plan outlines strategies to improve compatibility between Seattle-Tacoma International Airport and surrounding neighborhoods, focusing on water quality, drainage, and land use. Key programs include public acquisition of noise-impacted residential areas for open space and recreation, conversion of single-family zones to higher-density or commercial uses, and reinforcement of existing neighborhoods through noise remedy and infrastructure improvements. The plan also addresses environmental concerns such as stream protection, holding pond systems for stormwater management, and pollution control near Miller and Des Moines Creeks. -

2024-10-18Proposed Des Moines Creek Business Park West Development: Hearing Presentation by Laura Hartema, Friends of Des Moines Creek
Laura Hartema of Friends of Des Moines Creek presented concerns about the proposed Des Moines Creek Business Park West Development (File #LUA2022-0044) in October 2024, highlighting significant environmental impacts including the removal of over 500 trees, filling of wetlands and streams, and more than 30 acres of site disturbance. The presentation compared 1936 and 2023 aerial photos showing the area remains largely forested, and raised issues such as arsenic in soils, stormwater management concerns, and negative effects on neighboring residential properties. The group argues the project requires more thorough environmental review to demonstrate it will not cause significant harm to critical natural areas and the surrounding community. -
