All drainage and discharge from a sump pump, roof drain, gravity
drain, floor drain, surface drain, subsoil drain, foundation/footing
drain, and/or leader pipe shall comply with all of the following:
A. The drainage and discharge location shall not create a public nuisance
(as defined by the Township.)
B. The drainage and discharge shall not create a buildup of icing, standing
water or algae growth on any street, sidewalk, public right-of-way,
or adjacent property. In no case shall drainage and discharge be directed
across a sidewalk or walkway or onto a street. If curbing is present,
no drainage pipes shall pass through the curb to direct the drainage
and discharge onto the street.
C. No drainage or discharge shall be directed to any on-lot sanitary
sewer system or public sanitary sewer.
D. The drainage and discharge shall not be directed to any adjacent
property in a manner that causes damage or creates a nuisance and
shall not be discharged from a hose, pipe, or drain any closer than
20 feet from the property line unless permission is granted by adjacent
property owner. No drainage or discharge pipes shall extend beyond
the building envelope for the lot unless they are directly connected
to an infiltration facility, detention basin, storm sewer pipe, or
as approved by the Township.
E. To the maximum extent practicable (as determined by the Township
Engineer), all drainage and discharge shall be directed to infiltration
or vegetative BMPs or a storm sewer system connected to such BMPs,
or when such BMPs are not available, to vegetated basins or other
stormwater management areas with sufficient capacity.
F. Where connections in accordance with §
134-804E above are not possible, all drainage and discharge shall be directed towards and/or connected to a natural watercourse, drainage swale, or stormwater easement; if such direction and connection is possible, is reviewed by, and determined necessary and acceptable by the Township Engineer.
G. Where connections in accordance with §
134-804E and
F above are not possible or approved by the Township Engineer, all discharge and drainage shall be discharged upon the property that produced it in such a fashion as to provide the greatest chance for it to infiltrate before exiting the property.
H. Drainage and discharge shall be considered in stormwater management
calculations to demonstrate that conveyance and receiving facilities
have adequate capacity.
