A survey of every proposed subdivision and the preparation of preliminary and final plats of the subdivision shall be prepared by a registered land surveyor who shall certify on the plat that it is a true and correct representation of the lands actually surveyed. All surveys shall conform to standard practices and principles for land surveying.
(Ord. 428 § 16.08.092, 1998)
(1) 
The surveyor shall furnish the town engineer with a full set of survey notes which notes 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;
(d) 
The base meridian referred to.
(2) 
A traverse of the boundaries of the subdivision and all lots and blocks shall close within one foot in 5,000 feet, as required by Chapter 332-130 WAC.
(3) 
Primary survey control points shall be referenced to section corners and monuments, and corners of adjoining subdivisions, or portions of subdivisions shall be identified and ties shown.
(Ord. 428 § 16.08.094, 1998)
(1) 
Permanent control monuments shall be established at:
(a) 
All controlling corners on the boundaries of the subdivision;
(b) 
The intersections of centerlines of roads within the subdivisions;
(c) 
The beginning and ends of curves on centerlines;
(d) 
All block corners.
(2) 
Permanent control monuments may be placed on the offset lines. The position and type of every permanent monument shall be noted on all plats of the subdivision. Permanent control monuments shall be of a type approved by the town engineer.
(3) 
Permanent control monuments within the streets shall be set after the streets are graded. In the event a final plat is approved before streets are graded, the security deposit to provide for grading shall be sufficient to pay the costs of setting the monuments estimated by the town engineer.
(4) 
Each lot corner shall be marked by a three-quarter-inch galvanized iron pipe, 24 inches in length, or approved equivalent, driven into the ground, set with C cap per the requirements of RCW 58.19.120.
(Ord. 428 § 16.08.096, 1998)
If any land in a subdivision is contiguous to a body of water, a meander line shall be established along the shore at a safe distance back from the ordinary high water mark. Property lying below and beyond the meander line shall be defined by distance along the side property lines extended from the meander line. If the thread of a stream lies within a subdivision or forms the boundary of a subdivision, such thread shall be defined by bearings and distances as it exists at the time of the survey.
