Various Data Sources, Compiled by Kitsap County DCD/GISCritical Aquifer Recharge Areas means those land areas that contain hydrogeologic conditions that facilitate aquifer recharge and/or transmit contaminants to an underlying aquifer. Critical aquifer recharge areas under this title may be established based on general criteria, specifically designated due to special circumstances, or based on scientific studies and mapping efforts. Factors considered in the identification of critical aquifer recharge areas include depth to water table, presence of highly permeable soils (specifically Group A Hydrologic Soils), presence of flat terrain, and the presence of more permeable surficial geology. Category II critical aquifer recharge areas are areas that provide recharge effects to aquifers that are current or potentially will become potable water supplies and are vulnerable to contamination based on the type of land use activity. Category II critical aquifer recharge areas include: 1. Highly Permeable Soils (Group A Hydrologic Soils). 2. Areas above shallow aquifers and/or surface areas which are not separated from the underlying aquifers by an impermeable layer that provides adequate protections from contamination to the aquifer(s) below. 3. Areas above the Vashon Aquifer. Surface areas above the Vashon Aquifer which are not separated from the underlying aquifers by a poorly permeable layer that provides adequate protections to preclude the proposed land use from contaminating the Vashon aquifer below. Vashon aquifers in Kitsap County are typically mapped as "Qva" (Vashon advance aquifer) or "Qvr" (Vashon recessional aquifer) on geologic maps. 4. Areas with high concentration of potable water supply wells.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/6dba16428e3b41f8aa26efcb33ebcf62_0engOpen Data Kitsap County GISPublicCategory II Critical Aquifer Recharge Areas [Washington (State)--Kitsap County]Web servicesWashington (State)--Kitsap CountyWashington (State)Last Modified: 2025-10-09
