STORMWATER | SHORT FORM B - HI-INTENSITY


This component is for projects that have moderate impact on stormwater run-off.  Short Form B High's usually involve development of individual sites which are part of an approved Master Planned Commercial Subdivision. These subdivisions usually have stormwater management facilities in placed designed to handle the stormwater of individual lots. In most cases a landscape and/or tree removal element will be associated with a SFBH. The following are the most common situations that require a Stormwater Short Form B - High Intensity permit:

  • Development of a commercial structure within a Master Planned Subdivision.
  • Development of a duplex or triplex within a Master Planned Subdivision.
  • Redevelopment activities with greater than 1000 square feet of disturbed area within a Master Planned Subdivision.
