12 <br /> September 9, 2015 <br /> Page 2 <br /> GIS contours are now provided outside of the approximately 100' wide <br /> surveyed corridor along the proposed roadway. The GIS elevations do <br /> not precisely match the as-surveyed elevations but they are within an <br /> acceptable tolerance and the slope trends are generally consistent. <br /> 2. Illustrate potential wetlands and note regarding USAEC 404 Permitting <br /> requirements. <br /> The northern wetlands and the associated buffer are now shown as they <br /> were indicated by S&EC using GIS location data. The southern <br /> wetlands is currently under re-review by S&EC and we anticipate <br /> reclassification shortly. Consequently, we currently show no buffer <br /> around the indicated area. If, after review, any work affecting any <br /> wetlands is indicated, the proper 404 permits will be acquired prior to <br /> construction. <br /> 3. Illustrate "Edges of pavement" along Erwin and Whitfield roads; <br /> Edges of pavement have now been added to Erwin and Whitfield roads <br /> past the boundaries of the Henderson Woods property. The EOP is <br /> based on GIS data and surveyed rights-of-way for the roads. <br /> 4. Illustrate existing trees stands/tree lines with sample vegetation and <br /> specimen trees with types heights, Caliper/DBH (e.g. 60% evergreen trees <br /> primarily loblolly pines range in height from 30-60' in height and 10"-32" <br /> caliper inches in size as measured from Diameter Breast Height; and 40% <br /> understory and canopy hardwoods...."); <br /> Existing tree lines have been added to the drawings based upon <br /> Orange County GIS orthophotos of the site. The site consists of a mix <br /> of both mature evergreen and deciduous trees. However, as a formal <br /> tree survey is not required by the UDO, tree caliper, height and <br /> species mix have not been indicated on the plans as they have not <br /> been determined. <br /> 5. Illustrate septic systems and additional wells on the property with notes <br /> regarding removal; <br /> A note regarding proper abandonment of the existing well and septic <br /> field has been added. <br /> 6. Note sources for data; and <br /> A note listing the sources for the various data presented on the plans <br /> has been added to the lower left corner of the page. <br />
