(A) Purpose. The purpose of this district is to protect and preserve agricultural land resources in large parcels, and prevent urban sprawl consisting of scattered, low density residential development. Urban sprawl may necessitate the premature, and long-term inefficient extension of urban services, and hinders or prevents the establishment of sustainable, viable suburban development once the full array of municipal services becomes available.
