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").
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.
Any person who erects, constructs, alters, repairs, converts, maintains, or uses any building, structure or land which is part of a non-major development, in violation of this chapter, shall be subject to the penalties prescribed under §§
184-193 and
184-194 of the Borough Code.
