Alaska Administrative Code › Title 11 - Natural Resources › Part 6 - Lands › Chapter 53 - Records, Surveys, and Platting › Article 2 - Survey and Platting Standards › 11 AAC 53.150 - Supplemental cadastral rectangular surveys

Current through May 31, 2024
(a) Supplemental
				  cadastral rectangular surveys are divided into four categories, each of which
				  is surveyed to Class IV standards. If from time to time the Bureau of Land
				  Management, or other authority or agency, establishes procedures that differ
				  from those set out in the four categories, the division will issue special
				  survey instructions for the official positioning of monuments.
(1) Category I applies if no rectangular
				  cadastral survey corners have been set to define the rectangular survey
				  township perimeter. The township is, therefore, legally described only by
				  reference to the official protraction diagrams. The section corner positions
				  along the perimeter and within the interior of the township must be established
				  at the official protracted geodetic positions as shown on the official
				  protraction diagram.
(2) Category
				  II applies if monumentation exists on the perimeter of a township that is
				  officially platted. All subsequent section, quarter section, and other corner
				  positions must be located along the perimeter on line and at prorated distances
				  between the monumentation of record. All interior section corner positions must
				  be established at the official geodetic positions as shown on the official
				  protraction diagrams. The interior section lines along the exterior one mile of
				  the township must then be established as a line connecting the established
				  geodetic positions of the interior section corners and the section corner
				  positions as established on the exterior of the township. Whenever interior
				  correction lines have to be established, because the configuration of the
				  township exterior is not established at the official protraction positions, the
				  division will issue special survey instructions for the official positioning of
				  the correction line and corner monument positions.
(3) Category III applies if the perimeter of
				  the township has been established and monumented, based on the official
				  protraction diagrams, and interior monumentation defining a particular section
				  of land also exists, based on the official protraction diagrams. When this
				  situation exists, a section of land may be located within the interior portion
				  of the township by continuation of the rectangular survey system in accordance
				  with the approved protraction diagrams, using either the monumented interior
				  section corners or the exterior perimeter section corner monuments, whichever
				  is more appropriate. The rectangular system is then projected to within one
				  mile of the other previously established section corner monument. Then the line
				  connecting the existing corner and the newly established section corners is
				  made and the quarter corner is set at midpoint and on line. However, if the
				  connecting line does not close within the survey class accuracy assigned, a
				  correction line is required and the division will issue special survey
				  instructions to govern its location.
(4) Category IV applies if the perimeter
				  boundary of a township has been established and monumented, based on either an
				  official protraction diagram or on an older perimeter boundary survey done
				  before the official protraction diagrams were approved. It also applies when
				  the interior section corners have been established and monumented, based on
				  either an official protraction diagram or an older survey done before the
				  official protraction diagrams were approved. There are two survey data to
				  contend with, one that controls the exterior boundary of the township and one
				  that controls the interior section corners. Both may be physically monumented
				  on the ground. If two such data exist, the division will issue special survey
				  instructions establishing a correction line to control the basis for projection
				  of the rectangular survey system throughout the township. These special survey
				  instructions will govern the interior subdivision of the township.
