Cluster-style developments are only available in areas where there exists sewer unless handled by a PUD (Planned Unit Development).

(Prior Code, § 10.200.0410)

The R-1A Cluster Residential District is intended to establish standards for an alternative form of development for the provision of open space through the clustering of lots and thus minimizing the impact upon the land as well as providing for the efficient use of public services and facilities.
