The evaluation i.s based on <br /> . ERCD's comprehensive resource GIS database, a site visit, and the findings from iwo � <br /> previous surveys of the Greene Tract—a.cvltural resource survey by TRC Garrow <br /> A.ssociates (2000) an.d a biological resources survey by Robert Goldstein and Associates <br /> (20�0). Tlus has been augmented by stream buffer infarmation obtained.from the Town <br /> of Chapel Hill Planning Department <br /> The cultural resources survey(TRC Ganow)identified iwo h.istoric sites that are <br /> potentially eligible for the Natianal Regi.ster of Historic Places. Those twa former home <br /> sites are shown on the attached map(Figure 1)as the Byrd House Site and the Potts <br /> House Site. The survey recommended that any land disturbing or human activities shauld . <br /> attempt to avoid these sites and their immediate environs, for possible future <br /> archaeological work. However,neither of these sites is within the Possible Tract 2 <br /> E�ansion Area, and develapment in.the propased e�ansion area would not impact <br /> either of the two historic sites. <br /> The biological resource svrvey(Goldstein&Associates)identified the proposed <br /> expansion area as pine-d.omi.na.�ed.forest A review of historic aerial photos suggests that <br /> � this part of the forest is somewhat older than the adja.cent Affordable Housing area. <br />
