2021 Oregon Revised Statutes|Volume : 03 - Landlord-Tenant, Domestic Relations, Probate|Chapter 092 - Subdivisions and Partitions|Section 92.060 - Marking subdivision, partition or condominium plats with monuments; types of monuments; property line adjustment.

(1) The initial point, also known as the point of beginning, of a plat must be on the exterior boundary of the plat and must be marked with a monument that is either galvanized iron pipe or an iron or steel rod. If galvanized iron pipe is used, the pipe may not be less than three-quarter inch inside diameter and 30 inches long. If an iron or steel rod is used, the rod may not be less than five-eighths of an inch in least dimension and 30 inches long. The location of the monument shall be with reference by survey to a section corner, one-quarter corner, one-sixteenth corner, Donation Land Claim corner or to a monumented lot corner or boundary corner of a recorded subdivision, partition or condominium plat. When setting a required monument is impracticable under the circumstances, the county surveyor may authorize the setting of another type of monument. (2) In subdivision plats, the intersections, the initial point, also known as the point of beginning, the point of ending, points of curves and points of tangents, or the point of intersection of the curve if the point is within the pavement area of the road, of the centerlines of all streets and roads and all points on the exterior boundary where the boundary line changes direction, must be marked with monuments either of galvanized iron pipe or iron or steel rods. If galvanized iron pipe is used, the pipe may not be less than three-quarter inch inside diameter and 30 inches long. If iron or steel rods are used, the rod may not be less than five-eighths of an inch in least dimension and 30 inches long. When setting a required monument is impracticable under the circumstances: (a) The county surveyor may authorize the setting of another type of monument; or (b) The county surveyor may waive the setting of the monument. (3) All lot and parcel corners except lot corners of cemetery lots must be marked with monuments of either galvanized iron pipe not less than one-half inch inside diameter or iron or steel rods not less than five-eighths inch in least dimension and not less than 24 inches long. When setting a required monument is impracticable under the circumstances: (a) The surveyor may set another type of monument; or (b) The county surveyor may waive the setting of the monument. (4) A surveyor shall set monuments with sufficient accuracy that measurements may be taken between monuments within one-tenth of a foot or within one ten-thousandth of the distance shown on the subdivision or partition plat, whichever is greater. (5) A surveyor shall set monuments on the exterior boundary of a subdivision, unless the county surveyor waives the setting of a particular monument, where changes in the direction of the boundary occur and shall reference the monuments on the plat of the subdivision before the plat of the subdivision is offered for recording. However, the surveyor need not set the remaining monuments for the subdivision prior to the recording of the plat of the subdivision if: (a) The registered professional land surveyor performing the survey work certifies that the remaining monuments will be set, unless the county surveyor waives the setting of a particular monument, on or before a specified date as provided in ORS 92.070 (2); and (b) The person subdividing the land furnishes to the county or city by which the subdivision was approved a bond, cash deposit, irrevocable letter of credit issued by an insured institution as defined in ORS 706.008 or other security as required by the county or city guaranteeing the payment of the cost of setting the remaining monuments for the subdivision as provided in ORS 92.065. (6) A surveyor shall set all monuments on the exterior boundary and all parcel corner monuments of partitions, unless the county surveyor waives the setting of a particular monument, before the partition plat is offered for recording. Unless the governing body provides otherwise, any parcels created outside an urban growth boundary that are greater than 10 acres need not be surveyed or monumented. (7) Except as provided in subsections (8) and (9) of this section, a property line adjustment must be surveyed and monumented in accordance with subsection (3) of this section and a survey, complying with ORS 209.250, must be filed with the county surveyor. (8) Unless the governing body of a city or county has otherwise provided by ordinance, a survey or monument is not required for a property line adjustment when the abutting properties are each greater than 10 acres. Nothing in this subsection exempts a local government from minimum area requirements established in acknowledged comprehensive plans and land use regulations. (9) The requirements of subsection (7) of this section do not apply to property transferred through a property line adjustment as described in ORS 92.010 (9)(e).
