To control post-construction stormwater impacts from regulated earth
disturbance activities, state water quality requirements can be met
by BMPs, including site design, which provide for replication of preconstruction
stormwater infiltration and runoff conditions, so that post-construction
stormwater discharges do not degrade the physical, chemical or biological
characteristics of the receiving waters, As described in the DEP Comprehensive
Management Policy (No. 392-0300-002, September 28, 2002), this may
be achieved by the following:
(1)
Minimization of impervious surfaces with semipervious or pervious
surfaces during site design.
(2)
Flow attenuation by use of open vegetated swales and natural
depressions.
(3)
Use of infiltration structures.
(4)
Stormwater detention/retention structures.
(5)
Use of water quality treatment BMPs to ensure filtering out
of chemical and physical pollutants.
(6)
Stream bank and streambed protective measures.
