Prospective Critical Areas Ordinance update process

San Juan County is currently reviewing and revising its Critical Areas Ordinance. The County expects to complete the process by the end of the year.

||| FROM SAN JUAN COUNTY COMMUNICATIONS |||

San Juan County is updating its critical areas protections, also referred to as the CAO. The CAO serves as key regulation to ensure that development does not harm water quality, groundwater recharge, wetlands, and some fish and wildlife habitats. The CAO includes regulations for tree protections, water quality buffers, and prescribed development standards within flood zones and geohazards. A final draft of the updated regulations is available for public review and comment here: https://engage.sanjuancountywa.gov/2026-critical-areas-ordinance-cao-update

Updating the Critical Area Regulations in San Juan County involves two, distinct, processes. The first is the adoption of regulations that apply throughout the County except in the Shoreline jurisdiction. The second is the adoption of the updated critical areas into the County’s Shoreline Master Program (SMP). The draft amendments to the SMP are available here: https://engage.sanjuancountywa.gov/2026-critical-areas-ordinance-cao-update . Amending the SMP requires coordination and approval of the Washington Department of Ecology (DOE). 

The County expects to complete updating the regulations in December of this year.

In order to complete the adoption process over the next four months, the Department of Community Development has created the following schedule:

1. Planning Commission Briefing on September 18, 2026. 
2. County Council Briefing on September 22, 2026. 
3. Planning Commission and Department of Ecology joint public hearing on October 16, 2026. 
4. County Council second touch on October 27, 2026. 
5. County Council public hearing on November 24, 2026.
