5 <br />SECTION IV-B-10 FLEXIBLE DEVELOPMENT <br />Section D DEVELOPMENT STANDARDS <br />D.2 Conservation-Cluster Option <br />A conservation-cluster subdivision is one in which building lots are grouped together <br />through a transfer of allowable density within the subdivided tract provided the transfer <br />of density within the subdivision does not increase the average density in any overlay <br />zoning district. In aconservation-cluster subdivision designed with density transfer, lots <br />smaller than the minimum lot size permitted in the zoning district are allowed provided <br />such lots and subdivisions are developed in accordance with the following standards: <br />• Land saved through lot size reductions shall consist of designated Primary <br />and/or Secondary Conservation Areas. <br />• The total amount of land set aside as Primary and Secondary Conservation <br />Areas shall equal the sum of all reductions in minimum lot area and shall <br />comprise at least thirty-three percent (33%) of the total land :area in the <br />subdivision. <br />• Both Primary and Secondary Conservation Areas shall be placed. in undivided <br />preserves which adjoin housing areas that have been designed more compactly <br />to create .larger conservation units that may be enjoyed by all residents of the <br />subdivision and, if possible, enjoyed, visually by .the general public. Such <br />undivided open space shall be accessible to the largest number of lots within the <br />development. To achieve this, the majority of hauselots should abut undivided <br />open space to provide residents with direct views and access. Safe and <br />convenient pedestrian access to the open space from all adjoining houselots <br />shall be provided, except in the case of farmland or other resource areas <br />vulnerable to human disturbance. The design must meet Section F Evaluation <br />Criteria which sets forth conservation area design characteristics. <br />• Where undivided open space is designated as separate non-contiguous parcels, <br />no parcel shall consist of less than three (3) acres in area, nor have alength-to- <br />width ratio in excess. of 4:1, except such areas that are specifically designed for <br />neighborhood commons or greens; playfields; buffers adjacent to wetlands, <br />watercourses, and rural roads; wildlife corridors; or trail links. <br />• Each lot must contain a buildable area of sufficient size to accommodate a <br />single-family detached dwelling and customary accessory uses, including, but <br />not limited to, storage buildings and garages, patios and decks, lawns, <br />driveways, septic systems including repair areas and well sites. Aseptic <br />system and/or well site may be located in a secondary conservation open <br />space area provided it does not occupy more than one quarter of the <br />secondary conservation area No <br />g:\fxtamend\flexdev\adminrec.doc\8-17-99\kl <br />
