1*Any additional and/or new use of water, such as outdoor and stockwater uses, require mitigation. DWE only issues mitigation for outdoor and stockwater use on properties with an existing dwelling or pending building permit for a plumbed structure.*

2 Any approved and maintained water use prior to the Dungeness Water Rule (January 2, 2013) is not subject to the rule and does not require mitigation.

3 In order to maintain a right to water in WA state, the water must be beneficially used at least once every 5 years.

4 Mitigation Applications require an active Building Permit or Land Division number to be processed. Example projects: subdividing property, building a new home, building a new accessory dwelling unit.
