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.

Draft Wetland Inventory

The city of Sammamish is embarking on an update of its wetland inventory. Some results are available (see here). This inventory will be an ongoing process that is periodically updated. Included in this link is a map outlining the approximate boundary of each wetland and a “Wetland Rating Form - Western Washington”; which contains information about buffer requirements, the wetland classification and other important details. Please note a more complete map of critical areas within the city of Sammamish may be found through the NWMaps website (see here).
