Starting December 2, 2015, all new uses of groundwater in Kittitas County within the Yakima River Basin will need Water Budget Neutral Water Mitigation (WBN)
and need to be metered. Water Budget Neutral Mitigation is a withdrawal of water whose impact to area streams is offset by water from existing water rights
being left in stream. For new domestic uses, folks will need to purchase WBN mitigation for their new homes. They can buy mitigation from either a private
water bank or the Kittitas County Water Bank.
Kittitas County will offer 2 mitigation packages in the Green and Yellow zones of the Kittitas County Water Bank. The package available to each customer will be
determined by the parcel’s irrigation availability. Package A, only available to folks with access to other outdoor irrigation, will offer 275 gallons per
day indoor domestic use only and Package B, only available to folks without access to outdoor irrigation, will offer 275 gallons per day indoor domestic only
with 25 gallons per day for outdoor use up to 500 square feet. The packages offered through the Kittitas County Water Bank were determined by a Citizen’s Advisory
Committee and adopted by the Board of County Commissioners.
Eligibility review: The eligibility review will determine which Kittitas County Water Bank zone the parcel is in, how the parcel was created, well construction
requirements, and which mitigation process the customer will be eligible for.
Eligibility can be determined by searching the following map:

permit with Kittitas County Community Development Services.
