(b)

Markers and monuments shall be set as follows:

(1)

Along exterior boundaries at all angle points, and the beginning and ending of curves;

(2)

County approved monument wells shall be set along the center lines of all public streets at the intersection of all streets, centerline angle points, beginning and ending of curves, the center of all cul-de-sacs, and at the intersection with the exterior boundary as to maintain line of sight from monument to monument within the specified right-of-way. All monuments set in monument wells shall be no less in size than two inch brass or aluminum caps set on one and one-half inch galvanized steel pipe eighteen inches in length;

(3)

Monument kind, size, and location may be modified by the county surveyor as necessary on a case by case basis.

(c)

All street centerline intersections and centers of cul-de-sacs shall be referenced to four lead plugs and tags in curbs or permanently affixes with epoxy or similar adhesive except where well monuments have been set. Where no curbs are installed, such points shall be referenced to four lot corner monuments. Distances to said reference monuments shall be shown on eight and one-half by eleven inch transparent material and shall be filed in the county surveyor's office.

(e)

Front lot corners may be lead plugs and brass tags or tags permanently affixed with epoxy or similar adhesive set in the sidewalk or permanently affixed in the top of curb on prolongation of lot line or radially where point falls on a curve. Where no concrete curbs or sidewalks exist, actual front lot corners shall be monumented.

The types of markers and the sizes used at the above locations, and ties, where necessary, shall all be clearly indicated on the final or parcel map legend.

(g)

All monuments set shall be permanently and visibly with the certificate number preceded by the letters "L. S." or "R. C. E." as the case may be.
