Monument Preservation & Perpetuation | Bay Area 

Ensuring Legal Compliance and Protecting Vital Land Records

Before any road is paved or a sidewalk is replaced, the law requires that existing survey monuments be protected. Golden Gate Surveying provides professional Monument Preservation services to ensure that property corners, benchmarks, and street centerlines are accurately "referenced out" before construction and reset once work is complete.

Why Monument Preservation is Required

Under California’s Business and Professions Code §8771, survey monuments must be preserved during construction. Failing to do so can lead to costly legal disputes and the loss of essential property boundary data. We assist contractors and public agencies by:

• Pre-Construction Surveys: Locating and documenting existing monuments before they are disturbed by grading or paving.

• Filing Corner Records: Preparing and filing the required legal documentation with the County Surveyor.

• Monument Resetting: Precision installation of new monuments or brass discs after construction is finalized.

• Tie Notes & Referencing: Establishing "swing ties" to ensure the exact horizontal and vertical position of the monument is perpetually recorded.
