The R-3 Residence District is designed primarily
to make provisions for single-family residential development at low
and moderate suburban-type densities; to relate residential density
to environmental and health concerns by limiting development to low
density where water and sewer are to be on-lot, but allowing moderate
suburban-type densities when public sewer or public water service
is used; and to maintain the identify and character of existing suburban-type
residential neighborhoods.
