(1) The survey of every proposed subdivision, and the preparation of preliminary and final plats thereof, shall be made by or under the supervision of a professional land surveyor who shall certify on the plat that it is a true and correct representation of the lands actually surveyed;

(2) The surveyor shall furnish the City Engineer with survey notes (field notes in loose-leaf engineer’s notebook acceptable), which shall clearly show:

(a) The ties to each permanent monument;

(b) At least three durable, distinctive reference points or monuments;

(c) Sufficient data to determine readily the bearing and length of each line; and

(d) The base meridian referred to.

(3) A traverse of the boundaries of the subdivision and all lots and blocks shall close within the amount stated in WAC 332-130-090;

(4) Primary survey control points shall be referenced to section corners and monuments. Corners of adjoining subdivision or portions thereof shall be identified and ties shown;

(c) The beginning and end of curves on centerlines; and

Permanent control monuments shall be set in two-inch pipe, 24 inches long, filled with concrete with a brass inscribed pin attached, or shall be constructed of an approved equivalent;
