EXHIBIT C South 16 Street and Wharton Weems Boulevard are classified as secondary th thoroughfares and operate as collector streets west of SH 146 through the Port Crossing Commerce center and to the north to Fairmont Parkway. Just south of the site, South 16 Street transitions from a three-lane cross section to a rural 2-lane th cross section. Along the site frontage, the pavement is in fair to good condition, and while signing is in good shape, the pavement markings could use updating between Export Drive and Fairmont Parkway. H. Traffic Control Devices The study area consisted of one signalized intersection at Fairmont Parkway and South 16 Street and one signalized diamond interchange (at SH 146 and Wharton th Weems Boulevard). It also included several stop-controlled public intersections and private driveways. Each of the new site driveways were assumed to be one-way stop controlled on approach to South 16 Street. No warrants were examined for all-way th stop or signalization as site-related traffic volumes would not likely be of a magnitude to warrant other more restrictive traffic control at site driveways or cause them to be met at other existing intersections. I. Traffic Signal Timing and Phasing Traffic signal timing sheets were not explicitly obtained for the analysis, but timings recorded in the field were used to confirm basic timing parameters (yellow time, all- red clearance, cycle lengths, etc.). Traffic signal operations at SH 146 and Wharton Weems Boulevard were simulated with TTI 4-Phase with overlaps actuated operations. Signal timings at Fairmont Parkway and South 16 Street included th protected left turns with generally good operation for side street calls. Traffic signal timing parameters input into the Synchro model used for this study may include minimum green times, yellow and red clearance times, left turn lead/lag sequences, coordination parameters (coordinated phases and offsets), vehicle extension and minimum gap parameters and pedestrian timings. J. Right of Way The right of way available on South 16 Street was noted as 6 th of way is likely adequate for the functional classification and existing traffic operations characteristics of the roadway, but future expansion may require additional right-of- way. The developers should check with city staff to ensure that any requirements for right-of-way donation are satisfied before the site plan is finalized. Page 6 Voigt Associates, Inc.
