Section 11 AAC 53.690 - Plat standards under AS 40.15.300 - 40.15.380(a) The final subdivision plat must be clearly and legibly drawn to scale upon good-quality polyester film of Dupont Mylar or equivalent quality. Lines, letters, figures, certifications, acknowledgments, and signatures must be clear and legible. When filed, the plat must be in a condition that permits legible prints and negatives to be made from it for purposes of microfilming survey plats. Lines must be dense black, of consistent widths, and of recognizable width variations. A minimum size 00 pen or size leroy 80 or equivalent mechanical lettering and numbering template may be used for easement lines, details, and notes. Size 80 lettering must be uppercase. Sheets must be 18 inches by 24 inches, or 24 inches by 36 inches in size. Margin lines must be placed so as to leave a one-half inch margin on each of the three sides and a one and one-half-inch margin on the binding side.(b) If more than two sheets are required, an index map must be provided on the first sheet showing the entire subdivision and indicating the portion contained on each sheet. If more than one sheet is submitted, each sheet must be the same size. If more than one sheet must be used to accurately portray the lands subdivided, each sheet must show the particular number of that sheet and the total number of sheets included, and must show clearly labeled match lines to show where other sheets adjoin. All certificates must appear on the first or last sheet.(c) A scale of one inch equals multiples of 10 feet or of 100 feet must be used. The scale used must be both clearly stated and graphically illustrated by a bar scale drawn on every sheet showing any portion of the land subdivided.(d) A title block in the lower right corner of each sheet must show (1) the name by which the subdivision may be legally known;(2) a property description of the parent parcel showing the protracted or surveyed section, township and range, meridian, and total area in acres of the proposed subdivision;(3) the name and address of the registered land surveyor preparing the plat;(5) the date of survey and date of plat preparation;(6) the recording district; and(7) the platting authority (PA) number assigned by the department.(e) The name of the subdivision must be shown in bold letters. The subdivision name must be unique and must not be so similar to any name appearing on any recorded plat in the same recording district as to reasonably lead to confusion as to the legal identity of the subdivision. If the department determines that a subdivision name submitted does not comply with this subsection, the department will notify the applicant that the name must be changed in order for the plat to be approved.(f) The plat must have a vicinity map, a minimum of four inches by four inches, in the upper right-hand corner. The source and year of the base map used must be indicated. The vicinity map must show(2) townships and ranges;(3) any boundaries, including national forest and municipal boundaries; and(4) prominent physical or natural features, including roads, lakes, or rivers.(g) The plat must include the standard department legend, available on a form provided by the department, with the applicable symbols showing monuments recovered and set for the survey, as well as other monuments used. For purposes of this subsection, the standard department legend form, revised as of June 6, 2000, is adopted by reference.(h) Each sheet of the plat must depict a standard north arrow showing magnetic declination with source and date.(i) The basis of bearing must be clearly labeled within the graphics on the plat.(j) Sufficient survey data must be shown to positively describe the bounds of each lot, block, street, easement, and other area shown on the plat, as well as the outer boundaries of the lands subdivided. Record and measured data must be shown between all found and set monuments, with a listing of the sources of the record data. A complete description of monuments recovered and set must be shown on the plat.(k) Each linear measurement must be shown at least to the nearest 1/100th foot, and each angular measurement must be shown at least to the nearest 30 seconds. Each lot area must be shown to the nearest 10 square feet or to the nearest 1/100th of total acres.(l) For each line affected, curve data must be stated in terms of radius, central angle, and length of curve. However, curve data for streets of uniform width may be shown only with reference to the centerline, and lots fronting on those curves need show only the length of curve or of that portion of the curve that is included in their boundary. Lines intersecting curves must be labeled as "radial" or "non-radial."(m) If any lot or portion of the subdivision is bounded by a water body, and if a major discrepancy is clearly discernible between the current and record meander lines, both the current and record meander lines must be shown and delineated.(n) The boundary of the subdivision must be designated by a solid line that is wider than other lines appearing on the plat, and may not interfere with the legibility of figures or other data. The legal parcel identifier of adjacent lands must be shown.(o) Each parcel within the survey's exterior boundaries that is excepted from the survey must be clearly indicated and labeled, "Not a part of this plat."(p) Municipal or corporation boundaries within the parcel must be shown on the plat. Each road inside or adjacent to the parcel must be shown.(q) The plat must clearly show the location, width, and use of each easement. Each easement must be clearly labeled and identified. The source document creating easements of record must be cited.(r) Each lot and block must be numbered or lettered in consecutive order. All lots within each block must be numbered in consecutive order.(s) Each dedication must be clearly identified, indicated, or stated on the plat.(t) A street name shown on a plat filed for record must be unique within the locality except if the street is an extension of an existing street. An extension of an existing street must be named identically to the existing street.
