Farm Residential District
The Farm Residential District contains various critical environmental areas, and soils which are highly suitable for the cultivation of crops. The purpose of the District is: to encourage the use of prime agricultural soils for cultivation, to conserve critical environmental areas, and to limit the sprawling effect of development by encouraging the conservation of open space through a more compact arrangement of lots and buildings. The use of on-site domestic waste disposal is encouraged where appropriate in order to replenish the supply of groundwater. This District is within the zone of low groundwater capability (0-10 gpm) and the zone of severe to moderate soil limitations for on-site sanitary sewer systems.
