2025 Critical Area Ordinance Update
Board of County Commissioners Workshop
February 2, 2026
What are our Goals?
•Update code to meet state requirements
•Go through regulatory reform
•Fix conflicting and subjective language
•Reduce administrator’s authority in buffer reductions
•Documents reviewed by PC at the CAO Update Website
Clearing muddy waters with Regulatory Reform
Cleaning up the bluffs…
DCD updated the geologically hazardous areas code
JCC 18.22.530 to clarify existing requirements.
Simplified regulated activities in all critical areas to
anything not listed under general exemptions in JCC
18.22.230.
Clarified what regulations required within all
geohazardous areas and what regulations apply to
moderate and high landslide hazards and their buffers.
Cleaned up conflicting language throughout the
document.
Added restrictions for public facilities and utilities placed
landslide areas, tsunami areas, and seismic areas.
Reformatting!
(1)General standards for erosion and landslide hazards
Comprised of requirements clearing, grading, vegetation removal, stormwater…
Applies to all landslide hazard areas and erosion hazards
(2) Landslide hazard protection standards for moderate and high landslide hazards.
Lists out buffers for moderate and high landslide hazards.
Lists requirements for vegetation retention, new utility lines and access roads in hazardous areas or their buffers.
(3) Seismic hazard protection standards
Defers to JCC 15. Adds requirements for public infrastructure.
(4) Tsunami hazard protection standards
Adds requirements per state mapping in tsunami inundation areas and low coastal areas.
*Existing code has 16 different subsections
Site Potential Tree Height
(SPTH) Memo
Written by Shannon & Wilson
Responded to WDFW’s recommendations in “Riparian Ecosystems, Volume 2”.
Discussed the difficulty of implementing SPTH.
Analyzed the response of other jurisdictions to BAS recommendations.
Laid out all options and recommended larger standard buffers with a streamlined method of reducing buffers through vegetation enhancement.
Type of FWHCA Existing Buffer Proposed Buffer
Non-Fish Bearing Stream 50 or 75 ft depending on
grade of the stream.
100 ft
Fish Bearing Stream 150 ft

200 ft in rural county
150 ft in UGAs and LAMIRDs
Shoreline Streams
*regulated under JCC 18.25
150 ft 150 ft
Ponds under 20 acres 50 ft Dependent on connection to
streams:
•100 ft if connected to non-
fish stream.
•200 ft if connected to fish
stream.
•100 ft if not connected to
a stream.
Lakes over 20 acres

connections) OR 100 ft

Habitat Enhancement Plan
A plan developed by a qualified individual to achieve the
required enhancement. Typically includes a planting plan.
Well Vegetated Buffer
40% aerial cover of native trees and shrubs. Includes the
removal of invasive/non-native plants with native
vegetation.
Fully Vegetated Buffer
80% aerial cover of native trees and shrubs. Includes the
removal of invasive/non-native plants with native
vegetation.
New Terminologies
Agriculture
•Existing agriculture is exempt under general exemptions in JCC 18.22.230(4)(a).
•Agricultural Activities (defined in Section 18.10.010 JCC) is broad and allows for
land going fallow with no specific timeframes
•New agriculture in FWHCA, wetlands, or their buffers on areas not previously
farmed are subject to Article VIII Agriculture.
•Ag section reviewed by PC & Jefferson County Conservation District.
