000 9 Commissioner Marshall requested that wherever the conditions indicate "existing vegetation" that the type of vegetation and amount to remain be specified. Commissioner Walker questioned the necessity of the 100 foot buffer along Carolina Avenue and Collins explained that the 100 foot buffer is required along the property boundary regardless of what it adjoins. Planning Board member Barry Jacobs asked how the single family area plan was different from the project that was presented in the late 1970's for the same area and Collins indicated he was unfamiliar with the other plan. He asked if a report had been made on the thoroughfare plan for Hillsborough, and if sot if a copy could be obtained. Barry Jacobs also asked how much of the 100 foot buffer on each side of Nancy Hill Creek is in the floodplain and Collins explained, as shown on the plan, that the floodplain in some places extends beyond the 100 foot buffer and in other areas the floodplain is located within the 100 foot buffer. The 100 foot buffer generally includes the floodplain with the exception of the southeast portion. Commissioner Marshall asked why the condition regarding voluntary annexation recommended by the Town of Hillsborough was not included in the conditions. Collins responded that since the County is not involved in annexation and since it is a municipal policy► the County should not be involved. Commissioner Walker asked about the location of the Durham Loop and its affects on the project. Collins indicated that the location of the loop is not known at this time. PRESENTATION BY THE APPLICANT - John McAdams, facility engineer► presented Larry Meisner, engineer with Kimley-Horn and Associates► Inc. who made a report on the traffic impacts. He referred to the traffic impact analysis report which is in the permanent agenda file. He noted the proposed Scotswood development is served by several thoroughfares. Other future road developments that may have an impact on the proposed development would include the widening of I-85 to six lanes and I-40 which is currently under construction. There is a thoroughfare program being studied for the Hillsborough area and Central Orange County. He mentioned that Highway 70 has a 100 foot right-of-way that could be used to widen the road. The development would access onto US 70 and St. Mary's Road. The total development would generate 11,400 total trips with 5% of this total traffic occurring during the first phase of the project. The second phase would generate 70% of the total and the third and fourth phases would generate about 12% each. In all cases the existing volume and proposed volume would be under the capacity of the road. Regarding the improvements that would be required to accommodate the traffic, the applicant is in agreement with those recommendations outlined by NCDOT. Specifically, (1) that a traffic light be installed at the full buildup of the development, (2) left and right turn lanes at all the project entrances, (3) a left turn lane from St. Mary's to Highway 70 West► and (4) Carolina Avenue be changed to a cul-de-sac. Chair Willhoit asked if First and Second Avenues were paved and Meisner indicated there are no access points to these roads from the proposed development. Commissioner Carey asked about the four exits onto St. Mary's Road and McAdams indicated they are proposed to be 600-800 feet apart. Peter Kramer asked if the traffic from Treyburn along St. Mary's Road had been taken into account. McAdams responded that the impact of that
