[HISTORY: Adopted by the Mayor and Council
of the Borough of Fanwood 5-9-2006 by Ord. No. 06-08R. Amendments noted where
applicable.]
This chapter shall be applicable to any development
not classified as a major development under Chapter 255-6 (hereafter
referred to as a "non-major development").
A.
Stormwater management for non-major developments shall be reviewed by the Borough Engineer in conjunction with any application submitted to the Planning Board, including site plans, subdivisions and variances. In addition to materials required under Chapter 184 of the Borough Code, the applicant shall submit topographical information, design calculations, soil boring logs and other information related to stormwater management, if requested by the Borough Engineer. The Planning Board may specify stormwater management measures as conditions of approval.
B.
In cases where a non-major development does not require
Planning Board approval, but a building permit is required, the Borough
Construction Official shall forward a copy of each application for
a building permit to the Borough Engineer.
(1)
If the Borough Engineer determines that the non-major
development involves the construction or installation of an impervious
surface of less than 200 square feet, the Borough Engineer shall notify
the Construction Official who then may proceed with the normal business
of issuing a building permit without further consideration of stormwater
management.
(2)
If the Borough Engineer determines that the non-major
development involves the construction or installation of an impervious
surface of 200 square feet or more, the Borough Engineer shall review
the application for stormwater management. The Borough Engineer shall
return the application to the Construction Official with appropriate
comments and/or requirements to be incorporated as conditions of the
issuance of the building permit.
(3)
Any party aggrieved by any decision of the Borough
Engineer acting under this chapter as part of the building permit
process shall have the right to petition the Mayor and Council to
review the Borough Engineer's decision. If the Mayor and Council decide
that, due to the peculiar or unique circumstances of the matter, strict
compliance is not practical or would create an undue hardship, then
the Mayor and Council may, on such terms and conditions as they deem
appropriate, waive any requirements set forth by the Borough Engineer.
C.
In those cases where the non-major development requires
neither the approval of the Planning Board nor issuance of a building
permit, the non-major development shall be exempt from the requirements
of this chapter.
Except in particularly unusual situations to
be determined by the Borough Engineer, use of the following design
standards for a non-major development shall satisfy the requirements
of this chapter:
A.
Route each new downspout to prefabricated, high-density
polyethylene drywells with a nominal storage capacity of approximately
100 gallons.
B.
Route each new downspout to a stone-filled infiltration
trench with a volume of approximately 36 cubic feet (three feet wide,
three feet deep and four feet long).
C.
Route each new downspout to a rain garden with a minimum
area of 150 square feet.
D.
Existing downspouts may be similarly routed to offset
increased runoff from new patios, driveways and other increases in
impervious coverage.
E.
In each of the foregoing instances, provisions shall
be made for overflow of excess drainage. Overflows shall be discharged
to downstream pervious areas as sheet flow. Direct piping of downspouts
to the curb will only be allowed in situations where sheet flow is
impractical or would create hazards to property.
F.
All facilities shall be designed in accordance with
acceptable engineering practices subject to the approval of the Borough
Engineer. The Borough Engineer will supply greater specification of
these design guidelines upon request. The applicant's engineer may
submit alternate designs, which shall be subject to the approval of
the Borough Engineer if he/she finds that they are reasonably consistent
with this section.
The owner of any installation or system installed
under this chapter to control or regulate stormwater runoff shall
properly maintain such installation or system to ensure its correct
functioning.
