Subdivision Types:
• Standard Subdivision: Lots comply with established dimensional requirements for the
general use zoning district in which the property is located as well as the standards
detailed within Article 7 of the UDO.
• Cluster Subdivision: Required lot sizes, area, and setbacks can be reduced if at least
20% of the gross land area designated as common open space; and
• Flexible Development: Required lot sizes, area, and setbacks can be varied to
accommodate on-site features. Three types:
– Estate Lot (min. 4 acre lot size - only 2 acres developable)
– Flexible Development (33% open space required)
– Village (mixed use project – multiple housing types and land uses allowable)
Example: Henderson Woods
• Located in Rural Buffer Land Use Category (Comprehensive Plan) and Rural area per
Growth Management System Map,
• Density limited to 1 unit for every 2 acres per Joint Planning Land Use Plan/Agreement,
• Property was 48 acres in size resulting in 24 lots potentially available for development
based on density (48 acres / 2 = 24 lots),
• Minimum required lot size is 1 acre based on Joint Planning Land Use Plan/Agreement.
– STAFF COMMENT: Per existing subdivision regulations lot size, in certain
circumstances, can be reduced to as much as 65% of required area outside of
protected watersheds.

DIFFERENCES – CONVENTIONAL VERSUS FLEXIBLE (CONSERVATION CLUSTER)
Conventional subdivision:
• Open space part of individual lots. Can be disturbed,
• Subdivision encompasses entire parcel,
• More impervious surface area /land clearing/grading required (i.e. longer roads and
driveways),
• Greater impact to existing foliage and more acres ‘developed’ under conventional
subdivision design.
Flexible (Conservation-cluster):
• Smaller lots and separate open space (less likely to be disturbed),
• Open space is now ‘shared common area’,
• Subdivision is condensed requiring less land clearing and grading,
• Less impervious surface area required,
• Greater protection for existing foliage and less overall ‘development’ on property.
Commissioner Dorosin referred to the conventional model and asked if the open space
requirement only has to be met during construction.
Michael Harvey said there is no open space requirement in the conventional model. He
said the track is developed to the fullest extent.
Commissioner Dorosin referred to the flexible model and asked if the separate open
space must be maintained and undisturbed.
Michael Harvey said yes.
Commissioner Rich asked if Henderson Woods is conventional or flexible.
Michael Harvey said flexible, but construction has not yet begun.
Commissioner Dorosin asked if either model could have been approved.
