8 <br />Subdivision Types: <br />StandardSubdivision: Lots comply with established dimensional requirements for the <br />general use zoning district in which the property is located as well as the standards <br />detailed within Article 7 of the UDO. <br />Cluster Subdivision: Required lot sizes, area, and setbacks can be reduced if at least <br />20% of the gross land area designated as common openspace; and <br />Flexible Development: Required lot sizes, area, and setbacks can be varied to <br />accommodate on-site features. Three types: <br />Estate Lot (min. 4 acre lot size - only 2 acres developable) <br />Flexible Development (33% open spacerequired) <br />Village (mixed use project— multiplehousing types and land uses allowable) <br />Example: Henderson Woods <br />Located in Rural Buffer Land Use Category (Comprehensive Plan) and Rural area per <br />Growth Management System Map, <br />Density limited to 1 unit for every 2 acres per JointPlanning Land UsePlan/Agreement, <br />Property was 48 acres in size resulting in 24lots potentiallyavailable for development <br />based on density (48 acres /2 = 24 lots), <br />Minimumrequired lot size is 1 acre based on Joint Planning Land UsePlan/Agreement. <br />STAFF COMMENT: Per existingsubdivisionregulations lotsize, in certain <br />circumstances, can be reduced to as much as 65% of required area outside of <br />protected watersheds. <br />EXAMPLES (graphic) <br />EXAMPLES (graphic) <br />DIFFERENCES — CONVENTIONAL VERSUS FLEXIBLE (CONSERVATION CLUSTER) <br />Conventionalsubdivision: <br />Open space part of individual lots. Can be disturbed, <br />Subdivision encompasses entire parcel, <br />More impervioussurface area /land clearing/grading required (i.e. longer roadsand <br />driveways), <br />Greater impact to existingfoliage andmore acres `developed' underconventional <br />subdivision design. <br />Flexible (Conservation-cluster): <br />Smaller lots and separate openspace (less likely to be disturbed), <br />Open space is now `shared common area', <br />Subdivision is condensed requiring lessland clearing and grading, <br />Less impervious surface area required, <br />Greater protection for existing foliage and less overall `development' on property. <br />Commissioner Dorosin referred tothe conventional model and asked if the open space <br />requirement only has to be metduring construction. <br />Michael Harvey said there is no open space requirement in the conventional model. He <br />said the track is developed to the fullestextent. <br />Commissioner Dorosin referred tothe flexible model and asked if the separate open <br />spacemust be maintained and undisturbed. <br />Michael Harvey said yes. <br />Commissioner Rich asked if Henderson Woods is conventional or flexible. <br />Michael Harvey said flexible, but construction has not yet begun. <br />Commissioner Dorosin asked if either model could have been approved. <br /> 117
