Wetland area near Allen Lake.
Like many other counties and cities, Sammamish has recently updated its Critical
Areas Code provisions for protection of environmentally sensitive areas. Critical
areas include wetlands, streams and other fish and wildlife habitat conservation
areas, frequently flooded areas, geologically hazardous areas, and aquifer recharge
areas. The updated ordinance sets standards and criteria for development or other
activities proposed in and around critical areas. Amendments address allowed development
standards, buffer requirements and mitigation provisions.
Critical Area Code amendments were developed based on a review of the Best Available
Science (BAS) required by state law, while balancing other state requirements and
community goals. The BAS process required the city to develop a public record of
the scientific information, analysis and options related to specific critical areas
such as wetlands and streams.
As part of the process of updating of the city's Critical Areas Ordinance (SMC 21A.50,
), and in an effort to have extensive citizen involvement, the City Council formed
a Citizens Advisory Committee (CAC), charged with
providing community input on the update. All materials provided at the
CAC meetings, and subsequent Planning Commission and City Council meetings,
can be found in the links below.

The city intends to follow the Growth Management Act’s requirements to provide “early
and continuous public involvement” and to substantively “include” and “consider”
Best Available Science (BAS) in Sammamish’s CAO amendment process.
The public involvement process will include the following:
- Available paper files and electronic records for review by the public.
- Information on city website, press releases, one or more open houses/workshops,
public meetings, and other mechanisms to provide for public review and involvement.
- A staff report that will discuss the information and analysis that was reviewed
to develop the recommended code changes.
- Presentation of key issues to the Planning Commission and City Council prior to
their discussion, deliberations and decision.
We would like to hear from you! Attend a public hearing or submit your comments

Best Available Science Process
The city will also follow state of Washington guidance for the BAS process, specifically
RCW 36.70A.172 and WAC 365-195-c00 through 925. The State guidelines say
that each jurisdiction should:
- Use BAS information from local, state, or federal natural resources agencies, and
consult with experts from those agencies.
- Use scientific information that has been developed through a valid scientific process
only (peer review, methods that can be replicated, logical conclusions and reasonable
inferences, quantitative analysis, proper context, properly referenced).
- Non-scientific information may supplement scientific information but is not a substitute
for scientific information.
- Demonstrate on the record that the city included and considered the policy and regulatory
- In cases of inadequate, incomplete or contradictory scientific information, consider
a cautionary approach that includes adaptive management and monitoring.
- Ensure special consideration for anadromous fish by considering measures that protect
important habitat for all life stages.
