Abstract: Critical Aquifer Recharge Areas
Purpose:

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.

Use_Constraints:

King County data are made available with the understanding that they shall be used exclusively by the obtainer or his/her authorized agents. Digital products may not be reproduced or redistributed in any form or by any means without the express written authorization of King County. 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.

Lineage:

Process_Step:

Process_Description:

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.

Process_Date: 20051212

Process_Step:

Process_Description:

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
