(a) The accuracy for all topographic surveys shall be determined by the following method:

The elevation represented by any contour line as plotted on the final plat shall not have a vertical error greater than one-half of the interval of the platted contours over 90% of the area covered. (E.g., 5-foot contour interval = 2.5 feet maximum vertical error.)

(b) Locations of significant items such as horizontal control lines or control points, buildings, utilities, roads, walks, trees, boundary, easements and setbacks, etc., shall be shown within scaling accuracy of and in relationship to the horizontal control line, or control points and each other.
