2025 Critical Areas Ordinance Update
Two-Phase Approach
Phase I – Required Updates (Adopted November 19, 2025, with Ordinance 2025-19)
Phase I of the CAO update focused on required changes to ensure compliance with state law (RCW 36.70A) and alignment with the latest guidance from the Washington Department of Commerce, Department of Ecology, and Washington Department of Fish and Wildlife. These updates were based on Best Available Science and reflect new requirements to protect critical areas. Required updates in Phase I included:
- Updated definitions and references to current state law and science
- Enhanced protections for anadromous fish habitat
- Adjustments to align with state guidance on wetlands and critical aquifer recharge areas
- Revised stream buffer widths and classifications
Phase II – Discretionary Amendments (Anticipated 2026)
Phase II will evaluate potential discretionary changes to improve clarity, usability, and alignment with community priorities. These updates are not mandated by state law but are an opportunity for the City to address local implementation challenges, streamline processes, and consider emerging issues such as climate resilience, habitat connectivity, and adaptive management strategies. Public engagement for Phase II is anticipated to begin in 2026.
Use the interactive map linked above to see if your property is affected by adopted changes to stream buffer widths in the 2025 Critical Areas Ordinance update, phase 1.
- Red streams on the map have amended buffer widths.
- Green streams do not have buffer amendments.

What Are Critical Areas?
- Wetlands (click for an info card with more information)
- Fish and Wildlife Conservation Areas
- Critical Aquifer Recharge Areas
- Frequently Flooded Areas
- Geologically Hazardous Areas
The Growth Management Act (GMA) requires all cities and counties in Washington to adopt regulations protecting “critical areas” in order to preserve the natural environment, wildlife habitats, and sources of fresh drinking water. Critical areas regulation also encourage public safety by limiting development in areas prone to natural hazards like floods and landslides. RCW 36.70A.030(6) defines five types of critical areas:
What is Best Available Science?
Jurisdictions must demonstrate that the best available science has been considered when creating their critical areas ordinance by documenting scientific sources that support their approach to regulating critical areas and explaining when policies depart from science-based recommendations. Chapter 365-195 of the Washington Administrative Code (WAC) serves as a guide for establishing what is considered the best available science. The Department of Commerce and the Department of Ecology provide helpful guidance on addressing the GMA’s best available science requirements.
