Wash. Admin. Code § 332-30-119
(1) Under RCW 79.125.450 state-owned second class shorelands on lakes legally determined or considered by the department of natural resources to be navigable, may be sold to private owners of abutting upland property where it is determined by the board of natural resources that the shorelands have minimal public value for uses such as providing access, recreation or other public benefit. The amount of shoreland subject to sale to any one individual shall be the amount fronting a lot within a recorded subdivision plat; or the greater of one hundred feet or ten percent of the frontage owned by the applicant outside of a recorded subdivision. However, it shall be in the public interest to retain ownership of publicly owned second class shorelands on navigable lakes where any of the following conditions exist:
(2) Prior to the sale of second class shorelands on a navigable lake, the department will:
(d) Make an appraisal of the value of the shorelands potentially available for sale or acquisition in accordance with as many of the following techniques as are appropriate to the parcels in question:
(i) The market value of shorelands as of the last equivalent sale before the moratorium multiplied by the percentage increase in value of the abutting upland during the same period, i.e.,
FMV = (V2/V1) x (S1)
FMV = Current fair market value of shorelands
S1 = Value of shorelands at time of last equivalent sale
V1 = Value of abutting upland at time of last equivalent shoreland sale
V2 = Current fair market value of upland to a maximum of 150 feet shoreward
