Kirkland site constraints
Kirkland critical areas, wetlands, streams, and slopes
Critical areas can change the buildable footprint, consultant scope, permit path, and schedule. City maps are a screening tool; field work by qualified professionals may be required.
Reviewed against official Kirkland sources · August 2026Know the five categories
- Wetlands.
- Fish and wildlife conservation areas.
- Frequently flooded areas.
- Critical aquifer recharge areas.
- Geologically hazardous areas, including landslide, erosion, and liquefaction hazards.
Screen a wider area
Kirkland advises assessment of properties within 125 feet of streams and 300 feet of wetlands. A qualified professional must determine actual wetland and stream conditions. Work in a geologically hazardous area requires a critical-area permit.
Do not rely on the map alone
Bring a survey, site observations, title information, and the right wetland, stream, geotechnical, civil, or habitat professional into feasibility before fixing the house location.
Action plan
What to do next
- 1
Turn on critical-area layers in Kirkland Maps.
- 2
Check the 125-foot stream and 300-foot wetland screening distances.
- 3
Engage the correct qualified professional.
- 4
Map buffers, setbacks, access, utilities, drainage, and trees together.
- 5
Confirm the permit path with Planning before design development.
