Washington Revised Code Title 79. Public Lands § 79.105.310. Aquatic lands--Rent for improvements

(1) Except as agreed between the department and the lessee prior to construction of the improvements, rent shall not be charged under any lease of state-owned aquatic lands for improvements, including fills, authorized by the department or installed by the lessee or its predecessor before June 1, 1971, so long as the lands remain under a lease or succession of leases without a period of three years in which no lease is in effect or a bona fide application for a lease is pending.

(2) If improvements were installed under a good faith belief that a state-owned aquatic lands lease was not necessary, rent shall not be charged for the improvements if, within ninety days after specific written notification by the department that a lease is required, the owner either applies for a lease or files suit to determine if a lease is required.
