Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to gam@nc.gov Good morning Sue; per our conversation this morning I have prepared a table of proposed buffer impacts and identified the buffers and impacted areas on the attached plans. As we discussed, I did not include the managed roadway shoulder or the existing sanitary sewer easement areas in the calculations. Also please note that the area of the culvert extension is bounded on the south side by the sanitary sewer easement and on the north side by residential landscaped areas and the footprint of the existing home. Consequently the actual buffer impacts are very limited. Thank you for your assistance with this and please don't hesitated to contact me if you have questions or require additional information.
