Lord v. Pierce County, 271 P.3d 944 (Wash. Ct. App. 2012)

(plaintiff constructed earthen levee on property without permit; county issued cease and desist order and required levee to be removed; plaintiff argued “common enemy” doctrine enables him to build levee to protect his property from further flooding and exempts him from local regulations; court holds common enemy doctrine serves only as defense to liability for damaging adjacent properties; doctrine does not exempt landowner from local regulations).
