iMAP Map Set: Sensitive Areas

Abstract

This map set includesDDES* map layers that may indicate the presence of environmental factors that could affect the desired or permitted use or development of land parcels in unincorporated King County (see Critical Areas Designation). The original data represented by the map layers in this set resulted from work done in 1991 as part of the Sensitive Areas Ordinance, and the layers are updated periodically according to King County Code section 21A.24.

In addition, this map set contains several layers important for the Critical Areas Ordinance (CAO). These include not only the CAO layers themselves, but also the Critical Aquifer Recharge Areas layer and the 2005 Surface Water Design Manual (SWDM) layers.

Possible Uses


This map set should be used for only general reviews of property characteristics. Even if the map set shows no sensitive areas coincident with a particular property, you should contact DDES* prior to making decisions about the potential use or development of a property.
