conditions continue to be present at the intersections of TH 10 and Ramsey and Armstrong Boulevards. Project traffic would cause the intersections on TH 10 to deteriorate to LOS F and would cause the stop -controlled intersection on Industry Avenue, Ramsey Boulevard, and Armstrong Boulevard to move into LOS E and F conditions during one or both peak periods. New intersections created by the project with Industry Avenue (see Figure 21.2) would operate in acceptable conditions with the exception of the central north -south street (NS3) at Industry Avenue during the PM peak period. The two new intersections of the east -west parkway (EW1) with Ramsey and Armstrong Boulevards would operate in unacceptable conditions during at least one peak period. Within the project site, the extension of Sunwood Drive would be the primary east -west connector street in the project site and is estimated to carry 10,000 to 13,000 vehicles per day (vpd) west of NS6 Street. Volumes on Sunwood west of Ramsey would be about 18,000 vpd as shown in Figure 21.2. West of NS6 Street, the volume on Sunwood Drive would be adequately handled by a two-lane cross section (one lane in each direction). However, left -turn lanes would be needed at cross streets. Between NS6 Street and Ramsey Boulevard, four lanes would be needed to accommodate the projected volumes. Two-way or all -way stop control at the intersections of Sunwood Drive internal to the site would provide LOS C or better conditions for the level of traffic projected at those locations, although the intersections with NS6 and/or N5 5 Streets may require signalization for acceptable PM peak hour operations. The EW1 parkway would carry about 3,600 vpd on the western end of the project and between 5,000 and 9,000 vpd on the eastern end. The proposed one -lane parkway cross section would be adequate for the segments of the EW1 parkway. The other east -west streets internal to the project, because of their discontinuous nature would carry less volume than either Sunwood Drive or the EW1 Parkway and would generally be under 4,000 vehicles per day (and some would be in the under 1,000 range). Two-lane cross sections and stop (or yield control on the lower volume ones) would be appropriate. The north -south streets internal to the project would carry slightly higher volumes, particularly the three streets that would have full access intersections with Industry Avenue. Those streets would have between 2,100 and 5,700 vehicles per day. The other north -south streets inside the project would be expected to have less than 2,000 vehicles per day, with the exception of the NS6 Street that serves the employment cluster in the southeast corner of the site, which would have upwards of 4,000 vpd. Two-lane cross sections and stop (or yield control on the lower volume ones) would be appropriate although signals may be required at the NS6 and/or NS5Streets intersections with Sunwood Drive. Summary of Environmental Impact, Direct environmental impacts due to the traffic analysis are addressed in Items 22 and 24, which address vehicle related air emissions, and dust, odors, and noise, respectively. 21-7
