Alaska Administrative Code › Title 11 - Natural Resources › Part 6 - Lands › Chapter 53 - Records, Surveys, and Platting › Article 2 - Survey and Platting Standards › 11 AAC 53.210 - General plat standards

Current through May 31, 2024
All plats that are presented to or prepared by the
					 division, with the exception of those types of surveys requiring specific data,
					 as defined within the individual category, must conform to these basic
					 standards unless prior approval for the change has been granted by the director
					 or it is necessary to comply with the standards of the municipal platting
					 authority.
(1) The base sheets must be
				  of good quality linen or mylar at least three mils thick, and be one of three
				  standard sizes: 18 inches by 24 inches, 22 inches by 36 inches, or 31
1
/2 inches by 34 inches. There are no exceptions to the
				  standard size requirement.
(2) The
				  sheets must have the official division title block and border
				  configuration.
(3) All line work
				  must be in the appropriate black drafting ink.
(4) All lettering on the plat must be in the
				  appropriate black ink and be accomplished with mechanical lettering
				  equipment.
(5) All line work and
				  lettering must be of professional quality and all line widths and lettering
				  sizes must be of such size that all information can be clearly shown without
				  overlap or confusion.
(6) When more
				  than one sheet is required, an index sheet must be added showing the entire
				  parcel, with the sheets in numerical order, and each sheet showing the sheet
				  number and total number. When more than one sheet is submitted, only the last
				  need have the approval certificates, but all sheets must be the same
				  size.
(7) The scale must be one
				  inch representing 100 feet unless a request for the use of another scale is
				  approved by the director.
(8)
				  Details, as necessary, must be shown at an appropriate scale.
(9) The plat must have a vicinity map, with a
				  scale of one inch representing one mile in the upper righthand corner, showing
				  sections, townships and ranges, boundaries such as national forest or municipal
				  boundaries, and other prominent physical or natural features such as roads,
				  lakes, or rivers. The source of the base map used must also be
				  indicated.
(10) Nomenclature of the
				  survey need appear in the title block only, unless the division specifically
				  states otherwise.
(11) The basis of
				  bearings and the origin of geographic coordinates must be shown. Bearings shown
				  must be true bearings, and distances shown must be in the foot unit reduced to
				  the true horizontal equivalent, or, at the director's discretion, in the metric
				  unit reduced to the true horizontal equivalent.
(12) Bearings and distances must be shown
				  within the accuracy commensurate with the class of survey being represented.
				  However, plats of Class IV surveys must indicate bearings rounded to the
				  nearest 15 seconds of arc and distances rounded to a tenth of a foot or to
				  one-half decimeter, as appropriate.
(13) In compliance with
				  P.L.
				  94-168, entitled "Metric Conversion Act 1975," a
				  metric bar scale must be shown on the plat, positioned directly above the title
				  block.
(A) The foot scale must be identical to
				  that used in the survey portion of the plat, with the metric scale adjusted
				  accordingly. Two equations must also be shown: 1 meter = 3.280833 U.S. survey
				  feet, and 1 U.S. acre = 0.4047 hectare. Universal Transverse Mercator (U.T.M.)
				  coordinates must be shown at the position control point of the survey, with the
				  delta alpha and zone number shown directly below. The division will provide
				  these values on request.
(B) A
				  second set of U.T.M. coordinate values must be shown where the basis of bearing
				  is ascertained. The grid U.T.M. bearing must appear on the plat, in
				  parentheses, together with the true bearing, and be labeled as such. On
				  request, the division will compute this information from field data.
(C) At the end of each property description,
				  in parentheses, the equivalent area must be expressed in hectares.
(D) The following note must be added to the
				  plat. "The U.T.M. and metric data is being shown hereon for information
				  purposes only."
