RIPARIAN ZONE: The area located between the water's edge of aquatic ecosystems (rivers, streams, lakes, ponds, springs and seeps) and upland areas, whose soils allow for or tolerate a high water table, and provide sufficient moisture in excess of that otherwise available locally so as to provide a more moist habitat than that of contiguous floodplains and uplands. Riparian areas are composed of interacting assemblages of plants, animals and aquatic communities whose presence is either directly or indirectly attributed to water influenced or water related factors. Riparian areas produce a diversity of vegetative forms, sizes and species and a density of vegetation that makes them among the most productive habitats for wildlife. Areas exempt from this definition are manmade agricultural structures and devices such as irrigation ditches, sprinklers, and artificial ponds, except when mitigation requires creation or replacement of wetlands and/or riparian areas.
ROOF ASSEMBLY: A system designed to provide weather protection and resistance to design loads.

STORMWATER QUALITY CONTROL PLAN: A plan to control pollutants transported in stormwater prior to pollutants entering waterbodies. Stormwater quality control plans in the context of these regulations refer to postdevelopment stormwater flows, rather than stormwater flows under construction conditions. Stormwater quality control plans should be based on best management practices (BMPs) such as avoiding direct discharge into waterbodies, minimizing directly connected impervious area, use of detention ponds, and other BMPs.

WETLANDS: As determined by the army corps of engineers or qualified environmental consultant, those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support and that under normal circumstances do support, a prevalence of vegetation adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas. For purposes of these regulations wetlands do not include areas that are saturated solely by the application of agricultural irrigation water.
