Section 11 AAC 53.190 - Monuments(a) Primary monuments must be established for surveys as set forth in this subsection. A primary monument must consist of a minimum two-inch diameter metal pipe, at least 30 inches long, with a minimum four-inch flange at the bottom. A minimum two-and-one-half-inch diameter metal cap must be permanently attached at the top. If both the cap and the pipe are of nonferrous metal, then additives with magnetic qualities must be permanently attached at both the top and bottom of the monument. Every primary monument cap must be permanently stamped with the year set, the surveyor's registration number, and the corner identification. This data must be orientated so that the data may be read when the reader is facing north. Monuments and accessories found in a disturbed condition must be returned to the original position and condition as nearly as possible or replaced so as to perpetuate the position. (1) Every survey must have a minimum of four primary monuments set or recovered within the bounds of the survey.(2) No portion of a survey or subdivision may be more than 1,320 feet from a primary monument.(3) All angle points along an exterior survey boundary must have a primary monument.(4) Primary monuments along an exterior boundary may not be situated more than 1,320 feet apart.(5) If adjacent exterior boundary monuments are not intervisible, then an intermediate primary monument that is intervisible must be set.(6) If an exterior boundary line is less than 2,640 feet but more than 1,320 feet long, then the intermediate primary monument must be set as close to the midpoint as practical.(7) If the point for a primary monument is in a place that would be impractical to monument because of natural obstacles such as water bodies, a witness corner must be set. The witness distance must be shown on the plat of survey, from the existing monument, as set, to the true corner position. Witness corners must always be set on a survey property line and at a distance considered reasonable and practical from the true corner point. Witness corners must comply with the standards for primary monuments.(8) If it is impractical to set the primary monument, one of the following may be substituted, with monument accessories as required in sec. 200 of this chapter:(A) a cross marked in a firm stone;(B) a cap grouted into a firm stone; or(C) a durable tablet containing a minimum of 1,000 cubic inches of concrete and a cap marking the actual corner point.(b) Secondary monuments must be used for property line curvature control, at interior angle points, and on interior lines that exceed 1,320 feet in length and are not monumented with primary monuments. Secondary monuments must consist of at least a five-eighths-inch metal rod, three feet long, with a one-and-one-half-inch cap attached at the top.(c) All other corners within the interior of a subdivision must be marked with reinforcing rods or iron pipes, or in a manner prescribed by the platting authority having jurisdiction.(d) The director may approve the use of monuments and accessories other than as required by this section and sec. 200 of this chapter, upon finding that specific field conditions so warrant.Eff. 3/27/80, Register 73Authority:AS 38.04.045
