Washington
Atlensa reviews wetland delineation reports for projects in Washington - catching errors before they reach the Seattle District or Walla Walla District, and flagging gaps in Washington State Department of Ecology compliance.

Regulatory Context
Washington's Growth Management Act requires all cities and counties to regulate wetlands through Critical Areas Ordinances, creating a patchwork of local regulations that layer on top of federal 404 permits and state SMA permits. Washington Ecology publishes its own Wetland Rating System (updated 2014) used for CAO-based buffer determinations - distinct from federal delineation methodology.
