covered with an
within 5% of the maximum impervious cover permitted by this chapter but not in excess thereof, or which is lawfully
to such impervious cover provisions, may expand the impervious cover on such
by a maximum of 5% of the
for the purpose of constructing a pool and/or wooden deck over a porous surface, provided that 125% of the volume of storm-water generated by the
is recharged for a 100-year storm event. The benefits of this expansion will further be subject to the following requirements:
(a) The area of
expansion for a pool shall not include the area of water surface and shall apply to coping and/or patio areas.
(b) The area of
expansion for a wooden deck shall apply only if the deck is constructed with a space between each plank and if the deck is constructed over a porous surface.
(c) The design and location of the recharge system must be approved by the Township Public Works Department. The Township may require that a percolation test be submitted with the
application showing rates sufficient to empty the system within 24 hours.
may not disturb steep slopes, woodlands or trees 8 inches in caliper or larger.
(d) If site conditions prohibit on-site recharge meeting the requirements of this section, the expansion shall not be permitted.

provided the following standards are met:
(a) For applications proposing
that result in up to 10% more impervious surfaces on the
site than what is currently permitted in the underlying zoning district, (i.e., the 25% limit is increased to up to 35%) stormwater management facilities shall be designed to release no more than 90% of the pre-
rate of run off for all regulated storm events, (i.e., the 1, 2, 10, 25, 50, 100
event.)
(b) For applications proposing
that result in between 10% and 20% more impervious surfaces on the
site than what is currently permitted in the underlying zoning district, (i.e., the 25% limit is increased to between 35% and 45%) stormwater management facilities shall be designed to release no more than 75% of the predevelopment rate of run off for all regulated storm events, (i.e., the 1, 2, 10, 25, 50, 100
event.)

B. Common driveways;
allocation. For the purpose of determining the amount of

served by a common driveway, the total
of that common driveway shall be allocated evenly among the
served, unless it is otherwise allocated in a recorded covenant approved by the Township and binding on the properties affected, in which case such recorded allocation shall control.
C. Where no
limitations are imposed within an overlay district, such limitations shall be the same as those applicable in the underlying district.
