In response to Paul's question, it does apply to new streets within a subdivision. However, it may also apply to existing adjacent streets. For example, an in-fill condo map boundary is established by a boundary survey of the block where the surveyor chose to establish the intersection by existing ties (no CL monument present). We would generally require an appropriate spike & washer be set at that location along with the corresponding number of ties. Applicable ordinance below:
21.20.030 Street centerline monuments.
A.
Whenever necessary in the opinion of the county surveyor, centerline monuments shall be set to mark the intersections of streets, intersections of streets with the tract boundary, or to mark either the beginning and end of curves or the points of intersection of tangents thereof, or other intermediate points.
B.
Each such monument shall be not less durable and substantial than:
1.
In asphaltic concrete or cement concrete pavements, a lead and track;
2.
In unsurfaced graveled or oiled surfaces, a two-inch iron pipe set not less than 12 inches below the surface, or at such depth as may be approved by the county surveyor;
3.
In bituminous macadam pavements, a spike not less than six inches long.
