[Ord. No. 130, 12/9/1991]

Provide an optional approach to community development with provisions
to permit more efficient utilization of land and of community facilities
and services.
(b)
Encourage innovative single-family residential land development that
will conserve open space and environmental amenities.
(c)
Protect environmentally sensitive areas from development pressures.
