These three alternatives are contained in Attachment 3. In addition to the high, medium, and low development intensity scenarios, the Mayors and Chair requested an examination of the entire Greene Tract, including the Headwaters Preserve, in an effort to preserve the most environmentally sensitive areas and to develop the most appropriate areas of the entire 164 acre Tract. As a result, staff amended the proposed conceptual plan, reconfiguring the Headwaters Preserve and the jointly owned areas. This reconfiguration maintains the same total acreage for each of the areas but aligns them differently. The reconfigured tracts were drafted with environmental staff from the Town of Chapel Hill, the Town of Carrboro, and Orange County in order to create new parcels which endeavored to protect environmental features and habitats located on site. The proposed reconfigured Headwaters Preserve area alternatives are also contained in Attachment 3. Attachment 4 includes land use and density outcomes for the different alternatives. Attachment 5 includes potential affordable housing outputs based on different affordable housing proportions. Greene Tract Conceptual Plans Information on Factors Considered During Creation Process The staff - created conceptual plans for the Greene Tract are a result of several months of iterations and input from a variety of staff from the three jurisdictions. While planning staffs were the lead on creating the conceptual plans, input was also sought and incorporated from environmental and stormwater staffs. The following information addresses some anticipated questions regarding why the conceptual plans are presented as they are. Environmental Features Although the Greene Tract lies entirely within the planning jurisdiction of the Town of Chapel Hill, 104 acres of the Greene Tract are co -owned by Orange County and the Towns of Chapel Hill and Carrboro while 60 acres are owned solely by Orange County. Planning staffs chose to apply the most stringent development regulation of the three jurisdictions when determining stream and wetland buffers and preservation of other environmental features such as forest types. For example, if one jurisdiction requires a 50 -foot stream buffer and another requires a 65 -foot stream buffer, a 65 -foot stream buffer was used as the stream buffer on the conceptual plan. The Upland Hardwood Forest areas were slated for preservation as at least one jurisdiction would normally request /require preservation of these types of forests if a development proposal were made. Road Configuration All previous planning efforts of the Greene Tract /Rogers Road area have strongly stated that Purefoy Drive and /or Lizzie Lane should not be the only access to the Greene Tract. Connections to the south, north, and /or east must be made. The early iterations of maps (not included in materials) sought to avoid a stream crossing and connected to Merin Road, near the southeast corner of the Greene Tract, by traversing the area between two stream buffer areas. However, this configuration was revised as
