What is a cadastral survey? The term cadastral survey refers to the official boundary surveys performed under the authority of Title 43 of the United States Code (U.S.C.). Cadastral surveys in general: create; mark; define; retrace; resurvey; and reestablish the boundaries and subdivisions of the public lands of the United States. By Title 43 U.S.C., the BLM is required to perform cadastral surveys on all Federal interest and Indian Country lands. In addition to performing official surveys on the public lands administered by BLM, Cadastral Survey also performs surveys for other Federal Agencies…Forest Service, Navy, Air Force, National Park Service, Fish and Wildlife Service, and the Bureau of Indian Affairs. Immediate goals of the Nevada program are to accomplish surveys necessary to provide legal and adequate descriptions of public lands identified for sale; exchange; or disposal, as well as define the boundaries of public lands in the intermingled public and private ownership patterns.
In Nevada, the GLO/Cadastral surveys were initiated in 1861. Current survey conditions in Nevada have approximately 40% of Nevada townships surveyed prior to 1910 and monumented with stone or wooden posts at the corner points. Another 30% are surveyed after 1910 utilizing metal post and brass cap monuments at the corner points. The remaining 30% is unsurveyed land.
