(3) Contours at vertical intervals of five feet or, in
the case of relatively level tracts, at such lesser intervals as may
be necessary for study as determined by the Planning Commission or
Township Engineer. In no case shall the contour interval exceed 100
feet horizontally. Where reasonably practicable, data shall refer
to known, established elevations or to United States Coast and Geodetic

shall be plotted.
(4) Location and character of existing buildings: the
location, species and size of trees standing alone (over six inches
in caliper measured at breast height); outer limits of tree masses;
the location of quarries, marshland and land subject to inundation;

proposed streets or buildings.
(5) Measured distances from the center line of streets
to buildings, large trees standing alone.
(6) The depth of the water table, noted on the plan or
in a separate report along with the location of the test borings.

being subdivided or developed, the buildings that are to be demolished
shall be indicated.
(9) A statement on the plan shall show the number of acres
being subdivided or developed, the number of lots, the type of buildings,
the character of buildings, linear feet of new streets, linear feet
of streets to be widened and average lot size.
E. Proposed improvements.
(1) Tentative cross sections and center-line profiles
for each proposed or widened street shown on preliminary plan, including
profiles for proposed sanitary sewers and storm drains, showing manholes,
inlets and catch basins.
(2) Preliminary design of any bridges, culverts or other
structures and appurtenances which may be required.
F. Flood-prone areas. Where the subdivision or land development
lies partially or completely in a flood-prone area or where the subdivision
or land development borders on a flood-prone area, the plan shall
include detailed information identifying the following:
(1) The location and elevation of existing and proposed
streets, water supply and sanitary facilities, building sites, structures,

the Township Engineer shall evaluate the Township road system which
is part of the haul route and shall again evaluate the haul route
at the time of acceptance of dedication of the development public

or to be removed and the means of protecting existing vegetation during

(c)
Approximate location of proposed buildings,
paving, utilities or other improvements.
