Z 10s Carolina. The Duke Forest ro P Pew south of Eubanks Road has been extensively logged, and is in the first stages of regrowth. North of Eubanks Road: Portions of the Duke Forest property north of Eubanks Road, on either side of Old NC 66 are included in the Meadow Flats swamp forest, which has been nominated for recognition and protection as a State Natural Heritage Area because of its significant flora and fauna,and because of its value as a wetland ecosystem. That nomination has been rejected several times by Duke University. The Meadow Flats area is immediately adjacent to the proposed Transition Area II boundary. Meadow Flats has also been documented in the Triangle Land Conservancy's Inventory as an area of Regional Significance. Bald Mountain, portions of which have also been nominated for Natural Heritage Area designation,but rejected by Duke,is located within Duke Forest on the west side of Old NC 86, immediately adjacent to the proposed Transition II boundary. Bald Mountain is documented in the Triangle Land Conservancy Inventory as of Medium Significance in the County because it is the only remaining undeveloped monadnock in the County,and is an excellent example of a mature chestnut oak forest. Chestnut Oak is now quite rare in the County, having been extensively lumbered. In the strictest sense,this County criterion for Transition Area designation is met only by the portions of Duke Forest south of Eubanks Road. The Carrboro Transition Area currently comes within 400 feet of the natural areas located north of Eubanks Road and on either side of Old NC 86, and the Rural Buffer buffer does not prohibit development adjacent to these natural areas, but rather permits it at one dwelling unit per two acre densities on septic tanks. The Town proposes that a 100 foot undisturbed vegetative setback be left between the proposed Transition Area II in. this area and the Duke Forest property to be designated PID- I,in order to provide protection for these natural areas. 4. SOIL CONDITIONS: The soils in the 400 foot strip in question do not differ significantly from those in the Transition Area II to the south or those in the Rural Buffer on the north. The predominant soil types found in this area are of two associations: the Georgeviile-Herndon-Tatum association predominates south or Eubanks Road,and the Iredell-Enon association predominates north of Eubanks Road on the east and west sides of Old NC 86. The Georgeville-Herndon-Tatum association, located generally south of Eubanks Road is characterized as gently sloping to moderately steep,well drained, with a surface layer of silty loam and a subsoil of clay loam,silty clay loam,silty clay, and clay. They have a moderately high potential for most urban uses, with low strength, shallow depth to bedrock,and high erosion potential offering the most severe limitations on urban development. The soils Can pose moderate to severe limitations on the use of septic tanks because of the clayey characteristics of the subsoils and the shallow depth to bedrock.- 5
