Storm sewer inlet means a structure through which stormwater is introduced into an 11971 underground conveyance system. 11972 "Stormwater," for the purposes of the VESMA, means precipitation that is discharged across 11973 the land surface or through conveyances to one or more waterways and that may include 11974 stormwater runoff, snow melt runoff, and surface runoff and drainage. 11975 "Stormwater conveyance system" means a combination of drainage components that are 11976 used to convey stormwater discharge, either within or downstream of the land-disturbing activity. 11977 This includes: 11978 1. "Manmade stormwater conveyance system" means a pipe, ditch, vegetated swale, or 11979 other stormwater conveyance system constructed by man except for restored stormwater 11980 conveyance systems; 11981 2. "Natural stormwater conveyance system" means the main channel of a natural stream 11982 and the flood-prone area adjacent to the main channel; or 11983 3. "Restored stormwater conveyance system" means a stormwater conveyance system 11984 that has been designed and constructed using natural channel design concepts. Restored 11985 stormwater conveyance systems include the main channel and the flood-prone area 11986 adjacent to the main channel. 11987 "Stormwater detention" means the process of temporarily impounding runoff and discharging 11988 it through a hydraulic outlet structure to a downstream conveyance system. 11989 "Stormwater management facility" means a control measure that controls stormwater runoff 11990 and changes the characteristics of that runoff including the quantity and quality, the period of 11991 release or the velocity of flow. 11992 "Stormwater management plan" means a document containing material describing methods 11993 for complying with the requirements of a VESMP or VSMP. 11994 "Stormwater Pollution Prevention Plan" or "SWPPP" means a document that is prepared in 11995 accordance with good engineering practices and that identifies potential sources of pollutants that 11996 may reasonably be expected to affect the quality of stormwater discharges. A SWPPP required 11997 under a VESMP or VSMP for construction activities shall identify and require the implementation 11998 of control measures and shall include or incorporate by reference an approved erosion and 11999 sediment control plan, an approved stormwater management plan, and a pollution prevention 12000 plan. 12001 "Subdivision" means the same as defined in § 15.2-2201 of the Code of Virginia. 1...
