The Legislature of the State of New Jersey has in N.J.S.A. 40:48-1
et seq., delegated the responsibility to local governmental units
to adopt regulations designed to promote public health, safety, and
general welfare of its citizenry. Therefore, the Township Committee
of the Township of Green, Sussex County, New Jersey does ordain as
follows.
[Ord. No. 2011-11 § 1.3]
It is the purpose of this chapter to promote the public health,
safety, and general welfare, and to minimize public and private losses
due to flood conditions in specific areas by provisions designed to:
a. Protect human life and health;
b. Minimize expenditure of public money for costly flood control projects;
c. Minimize the need for rescue and relief efforts associated with flooding
and generally undertaken at the expense of the general public;
d. Minimize prolonged business interruptions;
e. Minimize damage to public facilities and utilities such as water
and gas mains, electric, telephone and sewer lines, streets, bridges
located in areas of special flood hazard;
f. Help maintain a stable tax base by providing for the second use and
development of areas of special flood hazard so as to minimize future
flood blight areas;
g. Ensure that potential buyers are notified that property is in an
area of special flood hazard; and
h. Ensure that those who occupy the areas of special flood hazard assume
responsibility for their actions.
[Ord. No. 2011-11 § 1.4]
In order to accomplish its purposes, this chapter includes methods
and provisions for:
a. Restricting or prohibiting uses which are dangerous to health, safety,
and property due to water or erosion hazards, or which result in damaging
increases in erosion or in flood heights or velocities;
b. Requiring that uses vulnerable to floods including facilities which
serve such uses, be protected against flood damage at the time of
initial construction;
c. Controlling the alteration of natural floodplains, stream channels,
and natural protective barriers, which help accommodate or channel
floodwaters;
d. Controlling filling, grading, dredging, and other development which
may increase flood damage; and,
e. Preventing or regulating the construction of flood barriers which
will unnaturally divert flood waters or which may increase flood hazards
in other areas.

[Ord. No. 2011-11 § 5.3]
Located within areas of special flood hazard established in subsection
25-3.2 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply:
a. Prohibit encroachments, including fill, new construction, substantial
improvements, and other development unless a technical evaluation
demonstrates that encroachment shall not result in any increase in
flood levels during the occurrence of the base flood discharge.
b. If subsection
25-5.3a is satisfied, all new construction and substantial improvements must comply with Section
25-5, Provisions for Flood Hazard Reduction.
c. In all areas of special flood hazard in which base flood elevation
data has been provided and no floodway has been designated, the cumulative
effect of any proposed development, when combined with all other existing
and anticipated development, shall not increase the water surface
elevation of the base flood more than 0.2 of a foot at any point.
