Comprehensive Plan and Development Regulation Amendment Process

The Comprehensive Plan and Development Regulations amendment process provides an opportunity for the community to propose changes to the City of SeaTac's Comprehensive Plan and development regulations. The City reviews proposed amendments concurrently to ensure consistency between adopted policy and implementing regulations.

Proposed amendments may include:

• Changes to Comprehensive Plan goals, policies, maps, or text.
• Changes to zoning, land use, development, environmental, or other development regulations contained in the SeaTac Municipal Code.
• Related amendments to both the Comprehensive Plan and development regulations.

Concurrent Comprehensive Plan and Development Regulations Amendment Process

The City conducts a concurrent amendment process for Comprehensive Plan and Development Regulations amendments. Because development regulations implement the policies and vision of the Comprehensive Plan, amendments are reviewed together to ensure consistency and compliance with state law.
