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. The following data was used in the Critical Aquifer Recharge Area Analysis: ASGWC [recently updated] Areas Susceptible to Groundwater Contaminati sdh_tot5yr (utility_ext) filtered on "king" in the county field sdh_tot10yr (utility_ext) filtered on "king" in the county field KCWPHA_1yr (utility) filtered on "HG" in the WHPA field sole_source (attached in this e-mail) Sole aquifer data from EPA is in SDW.
This dataset covers all of King County with the exception of incorporated areas (incorporated as of November 3, 2004).
Dataset meets standard coverage QA/QC checks such as labelerrors, nodeerrors.

The King County susceptibility layer was based on best information available to the County and best judgment of the persons interpreting that information for the County at the point in time when it was collected and analyzed. The actual susceptibility of any area may differ from the representation found on the King County susceptibility layer. Data users should recognize this limitation and make provisions to consider other interpretations in the data in their planning and regulatory processes.
