b. PIPING. Other than the piping shown on the approved plans, only minimal amounts of
piping under driveways and roads is allowed within the low density area when it cannot be
avoided. No additional piping is allowed.
c. DISPERSED FLOW. The low density area has maximized dispersed flow of stormwater
runoff through vegetated areas and minimized the channelization of flow.
d. VEGETATED CONVEYANCES. Stormwater runoff that could not be released as dispersed
flow may be transported by vegetated conveyances with minimum side slopes of 3:1 (H:V)
designed to not erode during the peak flow from the 10-year storm event as defined in the
stormwater rules and approved by the Division.
e. CURB OUTLET SYSTEMS. Each designated curb outlet must convey stormwater runoff to a
vegetated conveyance or vegetated area as shown on the approved plans and
specifications. The conveyance must be maintained with a dense vegetated cover at a
minimum of 100' long, side slopes at 3:1 (H:V) or flatter, a minimum bottom width of 2 feet,
and a longitudinal slope no steeper than 5% to carry the peak flow from the 10-year storm at
a non -erosive velocity.
4. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause
erosion downslope of the discharge point.
5. VEGETATED SETBACKS. A 50-foot wide vegetative setback must be provided and maintained
in grass or other vegetation adjacent to all surface waters as shown on the approved plans. The
setback is measured horizontally from the normal pool elevation of impounded structures, from
the top of bank of each side of streams or rivers, and from the mean high waterline of tidal
waters, perpendicular to the shoreline.
