The engineer or surveyor making the survey for any subdivision in the county shall set durable monuments at all angle and curve points in the exterior boundary of subdivisions. Such durable monuments shall consist of two-inch cement-filled iron pipes, not less than two feet in length, set not less than six inches and not more than ten inches below finished grade, with the point marked with nail and metal tag with the certificate number of the surveyor or civil engineer setting it, each number to be preceded by the letters "L.S." or "R.E." respectively, as the case may be; provided, that whenever a point marking any of the locations above described occurs in improved areas such as a concrete sidewalk, curb, wall or paved roadway, such points shall be marked with a lead plug, tack, and the metal tag, or with a spike and metal tag securely set in the concrete or paving respectively. If, however, the point is too close to the edge of concrete work to permit the placing of the lead plug, then sufficient concrete must be removed to permit the placing of the iron pipe as above described.
