SB 5224: Protecting Land Survey Reference Markers

These proposed amendments to RCW 58.24 & 58.09 will fund investment in the maintenance and growth of Washington state property boundary infrastructure. This investment will be funded through a $10 surcharge levied on recorded documents.

This will establishes the Survey Monument Protection Program (SMPP). The SMPP will be a statewide program, administered by the PLSO, to award grant funds to counties, cities, WSDOT, and the PLSO, to recover and reset the survey monuments of the Public and Private Property Boundary Infrastructure

LSAW is organizing a grassroots campaign to support this bill.
