(1) In all cases where a cemetery authority has owned a site for a cemetery for more than 40 years and has during that period sold lots, subdivisions of lots, pieces or parcels of the cemetery for burial purposes and the grantee or party claiming through the grantee has not used portions of such lots, subdivisions of lots, pieces or parcels of the cemetery for purposes of burial and has not kept them free of weeds or brush, but has allowed them to remain entirely unused for more than 40 years or uncared for and unused for more than 20 years prior to the adoption of the resolution provided for in ORS 97.880, and such lots, subdivisions of lots, pieces and parcels of the cemetery are adjacent to improved parts thereof, and by reason of their uncared-for condition detract from the appearance of the cemetery and interfere with the harmonious improvement thereof, and furnish a place for the propagation of weeds and brush, thereby becoming a menace to adjacent property, such lots, subdivisions of lots, pieces and parcels of such cemetery, which are unused and uncared for as aforesaid, hereby are declared to be a common nuisance and contrary to public policy.
