Zoning

Low Density Residential District

The R-1 District is intended to provide an attractive, pleasant living environment at a sufficient enough density to maintain an adequate standard of physical maintenance and community service. The R-1 District encourages the compact development and the optimum utilization of land appropriate for residential use by encouraging higher density cluster and planned unit developments while simultaneously leaving sloping areas, floodplains and other unbuildable areas open and available for recreational and athletic purposes. The R-1 District discourages the intrusion of the commercial and industrial uses that so often have an annoying and deteriorating effect upon residential development.

Permitted uses

Include but are not limited to:

Community / recreation center
Religious facility
Housing-Single unit
Housing-Multiple units
Public service
Educational/school
Fire house
