Mapping Approach The combined agricultural dataset uses Washington State Department of Agriculture (WSDA) field data as well as BCD data, and removes rangeland on Hanford, and agricultural land in city limits. Where the data overlap, WSDA field level data serves as the primary dataset; areas not covered by WSDA would represent the BCD dataset; followed by other federal and state rangeland datasets. Under GMA, critical areas include fish and wildlife habitat conservation areas, wetlands, frequently flooded areas, geologically hazardous areas, and critical aquifer recharge areas used for potable water. Consistent with GMA, the Benton County regulates critical areas. General definitions are provided below. See the matrix below summarizing critical area designation and classification criteria in State laws and rules as well as the Benton County Code.

High vulnerability is 1 State Definitions and Classification County Definitions and Classification Mapping Sources and Notes indicated by land uses that contribute directly or Alluvial Geology: Derived from indirectly to contamination that may degrade NRCS Soil Geodatabase. groundwater, and hydrogeologic conditions that facilitate degradation. Low vulnerability is indicated by land uses that do not contribute contaminants that will degrade groundwater, and by hydrogeologic conditions that do not facilitate degradation. Hydrological conditions may include those induced by limited recharge of an aquifer. Reduced aquifer recharge from effective impervious surfaces may result in higher concentrations of contaminants than would otherwise occur. *** (4) A classification strategy for aquifer recharge areas should be to maintain the quality, and if needed, the quantity of the groundwater, with particular attention to recharge areas of high susceptibility. (a) In recharge areas that are highly vulnerable, studies should be initiated to determine if groundwater contamination has occurred. Classification of these areas should include consideration of the degree to which the aquifer is used as a potable water source, feasibility of protective measures to preclude further degradation, availability of treatment measures to maintain potability, and availability of alternative potable water sources. (b) Examples of areas with a critical recharging effect on aquifers used for potable water may include: (i) Recharge areas for sole source aquifers designated pursuant to the Federal Safe Drinking Water Act; (ii) Areas established for special protection pursuant to a groundwater management program, chapters 90.44, 90.48, and 90.54 RCW, and chapters 173-100 and 173-200 WAC; (iii) Areas designated for wellhead protection pursuant to the Federal Safe Drinking Water Act; (iv) Areas near marine waters where aquifers may be subject to saltwater intrusion; and DRAFT July 2016 | Benton County Voluntary Stewardship Program 2 State Definitions and Classification County Definitions and Classification Mapping Sources and Notes (v) Other areas meeting the definition of "areas with a critical recharging effect on aquifers used for potable water" in these guidelines. (c) Some aquifers may also have critical recharging effects on streams, lakes, and wetlands that provide critical fish and wildlife habitat. Protecting adequate recharge of these aquifers may provide additional benefits in maintaining fish and wildlife habitat conservation areas. Fish and Wildlife Habitat Conservation Areas WAC 365-190-030 (6)(a) "Fish and wildlife habitat Adopted: 15.40.020 (2) "Fish and Wildlife Conservation Federally-identified Critical conservation areas" are areas that serve a critical role in Areas" refer to the following: Habitat: USFWS dataset.
