R.I. Gen. Laws § 34-8-6
No coordinates based on either Rhode Island coordinate system, purporting to define the position of a point on land boundary, shall be presented to be recorded in any public land records or deed records unless such point is within one kilometer of a monumented horizontal control station and unless minimum THIRD ORDER - class II procedures are used in conformity with the standards of accuracy and specifications prepared and published by the federal geodetic control committee established in conformity with the standards of accuracy and specifications for first - or second-order geodetic surveying as prepared and published by the federal geodetic control committee (FGCC) of the United States department of commerce. Standards and specifications of the FGCC or its successor in force on date of the survey shall apply. The publishing of the existing control stations, or the acceptance with intent to publish the newly established control stations, by the national ocean survey/national geodetic survey will constitute evidence of adherence to the FGCC specifications. Above limitations may be modified by the Rhode Island department of transportation land surveying section to meet local conditions.
