Durable monuments shall be set at all angle and curve points on the exterior boundary of subdivisions, and at points not more than one thousand (1,000) feet apart in cases where exterior boundaries between any two (2) angle or curve points exceed said distance. Monuments shall be set as follows:

In areas subject to dishing, pipes must be set no less than six (6) feet deep, and in areas subject to commercial cultivation, no less than twelve (12) inches deep.

C. Acceptable substitute monuments are:

1. A lead, brass tack and tag set in concrete—L.T. & T.;

2. If the intersection is not improved with concrete curbs, set four (4) tangent ties, no less than four (4) feet from the centerline monument.

a. If the ties fall on the pavement, they shall be set approximately two (2) feet from the edge of pavement.

b. If in A.C., use six-inch monument spikes and tins.

d. If the ties must be set off of the pavement, use iron pipes of a two-inch outside diameter, thirty (30) inches in length, with concrete plugs and brass tacks, set in natural ground no closer than two (2) feet from the edge of pavement, and no less than six (6) inches deep;

3. Any substitute centerline tie should be approved in writing by the City Engineer before setting;
