Primary and Secondary <br />Conservation Open Space Areas located outside building envelopes shall be <br />restricted against further development through conservation easements and/or <br />deed restrictions. <br />(9) Estate lot subdivision road(s) shall be designed to provide internal access to all <br />lots in the subdivision. Private driveways shall access existing state maintained <br />roads only via subdivision roads providing internal access to lots in the <br />subdivision. <br />(10) A 100-foot Type F buffer meeting the requirements of Section 6.8.6 shall be <br />provided along the frontage of all existing state maintained roads adjacent to the <br />subdivision boundaries. <br />(a) In areas of dense mature forest, existing vegetation may be used to <br />fulfill the buffer requirements. <br />(b) If additional planting is required, new plant materials that satisfy the <br />buffer requirements of Section 6.8.5 shall be installed and maintained <br />in accordance with provisions of Section 6.8. <br />(B) 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 of <br />density within the subdivision does not increase the average density in any overlay <br />zoning district. <br />In a conservation-cluster subdivision designed with density transfer, lots smaller than the <br />minimum lot size permitted in the zoning district are allowed provided such lots and <br />subdivisions are developed in accordance with the following standards: <br />(1) Land saved through lot size reductions shall consist of designated Primary and/or <br />Secondary Conservation Open Space Areas. <br />(2) The total amount of land set aside as Primary and Secondary Conservation <br />Open Space Areas shall equal the sum of all reductions in minimum lot area and <br />shall comprise at least 33% of the total land area in the subdivision. For Minor <br />subdivisions utilizing this option, the minimum amount of open space may <br />increase beyond amount per UDO 7.12.4(A) (2). <br /> 201
