Learn how to use GIS Open Data 🗺
Summary
Developed as part of King County proposed amendments to it's Critical Areas Ordinance; it took effect on 01/01/2005.
State law required KC to review and update; if necessary; its CARA provisions in order to ensure that the county's regulations are adequately protecting aquifers that are used to supply drinking water and sustain King County's natural water systems.
Incorporated areas have been excluded from this layer intentionally, as this layer represents a unique land use standard defined only for unicorporated County areas.

From 2005 to 2008, King County Department of Natural Resources and Parks (DNRP) has contracted with GeoMapNW pursuant to an Interlocal partnership with the cities of Redmond, Woodinville and Issaquah, and the Sammamish Plateau Water and Sewer District, to remap geologic susceptibility in three new areas that are included in the proposed 2008 CARA update: Upper Issaquah Creek Valley, Redmond to Woodinville to Bear Creek Preston / High Point |

King County's existing CARA designation was adopted with the Critical Areas Ordinance in 2004. These designations are derived from existing susceptibility mapping based on data developed during the Groundwater Management Planning process in 1995 and new susceptibility mapping completed for Vashon - Maury Island in 2003. |
