(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;
(5) Permanent control monuments shall be established at:
(a) All controlling corners on the boundaries of the subdivision;
(b) The centerline intersections of all roads within the subdivision;
(c) The beginning and end of curves on centerlines; and
(d) All block corners.
(6) Permanent control monuments may be placed on offset lines. The position and type of every monument shall be noted on all plats of the subdivision. 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;
(7) Permanent control monuments within the street shall be set after the roads are graded. In the event a final plat is approved before streets are graded, the survey deposit to secure grading shall be sufficient to pay the costs estimated by the City Engineer of setting such monuments.
