King County Sensitive Areas Map Folio 2 . A series of maps prepared by King County
delineating Class III landslide hazard areas, Class III seismic hazard areas, erosion hazard areas,
wetlands, anadromous fish-bearing waters, 100-year flood plains, and water types. A copy of this
folio and unscreened maps of Area No. 5 are stored at the city department of community
development.
King County Wetland Inventory Notebook 2 . A study conducted by the King County planning

Each wetland is assigned one of three wetland ratings determined by examining the scores of
selected inventory tasks, specific data, and percentile rankings for various categories.
Landslide 3 . An episodic downslope movement of a mass of soil or rock that includes but is not
limited to rockfalls, slumps, mudflows, and earthflows.
