(2) Preserve views and vistas of the capitol buildings, Mount Rainier and the Olympic Mountains;

(a) Major commemorative works shall not serve solely to memorialize an individual. Major works of art may be gifted to the state or dedicated in memory of an individual so long as the nature and primary purpose of the work remains artistic or aesthetic, to serve as an object of public enjoyment rather than as a monument to an individual.

(b) Minor works shall honor individuals or groups of individuals only after the 10th anniversary of the individual's death or the death of the last surviving member of a group, when the enduring, historical, statewide nature of their achievements has been demonstrated and broadly acknowledged;

(c) Major or minor works commemorating an event, including a military event or conflict, may be proposed during the lifetime of those who engaged in it, but not sooner than the 10th anniversary of the end of the event.
