Site maps should be on a topographical survey map as required of
the preliminary plat or an enlargement of the most recent United States
Geological Survey quadrangle to a scale of one inch to 200 feet and
showing contours at intervals of not more than 20 feet; may be a freehand
sketch on a print of such a map; and must have:

Development data shall include:
B.
Site maps shall include:

invert elevation of sewers at proposed points of connection; direction
and distance of sewers not adjacent to tract to which connections
are proposed; and invert elevations at points of connection.
(4)
Topography:
(a)
For land with average slope of less than 2%, contour lines at
not more than one-foot intervals.
(b)
For land with average slope of 2% to 10%, contour lines at not
more than two-foot intervals.
(c)
For land with average slope exceeding 10%, contour lines at
not more than five-foot intervals.
(d)
Datum plane for all topographic information shall be that of
the United States Geological Survey.
(5)
Location of percolation test sites, if required.
B.
Site maps shall include:

(4)
Survey data: primary control points or descriptions and ties to such
control points to which all dimensions, angles, bearings and similar
data on map are referred. (Lands by owners' names are not to
be considered as bearing or control points.)
(5)
Information beyond subdivision boundary required for preliminary
plan need not be shown except for boundary streets.
