Forest buffers shall be extended to encompass the entire 100 year floodplain and a zone with minimum width of 25 feet beyond the edge of the floodplain.
When wetland or critical areas extend beyond the edge of the required buffer width, the buffer shall be adjusted so that the buffer consists of the extent of the wetland plus a 25 foot zone extending beyond the wetland edge.
The following land uses and/or activities are designated as potential water pollution hazards, and must be set back from any stream or waterbody by the distance indicated below:
storage of hazardous substances (150 feet)
above or below ground petroleum storage facilities (150 feet)
drainfields from onsite sewage disposal and treatment system (i.e., septic systems100 feet)
raised septic systems (250 feet)
solid waste landfills or junkyards (300 feet)
confined animal feedlot operations (250 feet)
subsurface discharges from a wastewater treatment plant (100 feet)
land application of biosolids (100 feet)
For development within 4000 feet of any water supply intake, the setbacks should be doubled.
The forest buffer shall be composed of three distinct zones, with each zone having its own set of allowable uses and vegetative targets as specified in this ordinance.
The function of the streamside zone is to protect the physical and ecological integrity of the stream ecosystem.
The streamside zone will begin at the edge of the stream bank of the active channel
and extend a minimum of 25 feet from the top of the bank.
Allowable uses within this zone are restricted to:
flood control structures
utility rights of way
footpaths
road crossings, where permitted.
The vegetative target for the streamside zone is undisturbed native vegetation.
The function of the middle zone is to protect key components of the stream and to provide distance between upland development and the streamside zone.
The middle zone will begin at the outer edge of the streamside zone and extend a minimum of 50 plus any additional buffer width as specified in Section VI C.
Allowable uses within the middle zone are restricted to:
