The Monroe County Survey Office maintains nearly 5,700 geodetic survey monuments and the right of way records for 650 miles of County highway.  The network of monuments forms a base survey to aid in the orderly growth of the community.  When properly used as reference, the network reduces land measurement inconsistencies.  Rules and regulations for the use and protection of the survey network are set forth in Local Law No. 6 of 1971, the authority for which rests entirely with the Monroe County Legislature. (Monroe County Monument Law)

The Department of Real Property Services negotiates the acquisition of property rights required for the construction and maintenance of County improvements including highways, traffic signals, bridges, sanitary and storm sewers, and fiber optic conduit. (A Guide For Property Owners - "How Monroe County Acquires Property For Public Purposes")

Please feel free to contact me with any questions regarding rights of way, easements, subdivision map review, monument protection or surveying in general.
