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 to mitigate through the Kittitas County Water Bank is determined by reviewing which Kittitas County Water Bank zone the parcel is in and how the parcel was created. Eligibility can be determined by searching on COMPAS, the Kittitas County online mapping service.
Please contact Kittitas County Public Health at 509-962-7515 with any questions about eligibility.
The processing time to obtain a water mitigation certificate using the OTC process is approximately two weeks. To purchase water mitigation through the OTC water mitigation process, complete the steps as outlined in the Kittitas County Water Bank Over-The-Counter Water Mitigation Process
Some parcels eligible to mitigate through the Kittitas County Water Bank will require Washington State Department of Ecology (Ecology) review and approval. The review time for these applications is six months-one year.
