Preliminary and final design for trail improvements to approximately 11 miles of railroad corridor from Pecos Road to east of Paradise Hills in Henderson NV. Improvements included 7.4 miles of asphalt “active” trail; 6.7 miles of soft-surface (decomposed granite) “recreation” trail; 22 entry courts; 24 waysides; 5 parking lots; trail and parking lot lighting; 10,180 sf of retaining wall; 13,970 sf of decorative wall; soil-nail retaining wall to facilitate an undercrossing of I-515; over 14 miles of 8-foot chain-link and welded wire security fencing; extensive landscaping; shade structure; 53-foot prefabricated bridge; 42-foot prefabricated channel bridge; preliminary grade-separated undercrossing and overcrossing designs of Stephanie; extensive storm drain improvements including 20 lf of double 12-ft by 5-ft RCBs, 8 lf of 83-inch by 53-inch HERCP, 290 lf of 60-inch RCP, 830 lf of 48-inch RCP, 260 lf of 36-inch RCP, 2,310 lf of 24-inch RCP, 270 lf of 18-inch RCP, 3,320 CY of riprap, and 6,390 sf of trail cross gutters with cutoff walls; and improvements at 13 street crossings, which included raised median, PBS paving, RR track upgrades, ADA-compliant sidewalk widening/ upgrades, and pedestrian crossing improvements that included median refuge treatments, signing and striping, rectangular rapid-flash beacons (RRFBs), and pedestrian hybrid beacons (PHBs).
Project included topographical survey, horizontal control plan, geotechnical investigations, hydrologic modeling and drainage analysis study, bridge type/tunnel selection report, utility coordination, trail/street crossing analysis report, NDOT permit, specifications, bid support services, and construction support services. Project required extensive grading design and coordination, and design of 28 water service connections for both irrigation and drinking fountains. Irrigation service configured to flush drinking water service to maintain water quality. Project included extensive multi-agency coordination with City depts., NDOT, SNWA, CCRFCD, FAST, PUC, and UPRR. Extensive NDOT coordination on both I-515 undercrossing and RR crossing improvements. SNWA coordination on trail improvements along 3 miles of 109-inch waterline. Extensive UPRR coordination on wireline and pipeline (irrigation) undercrossings of tracks, track improvements, and pedestrian/street crossing improvements. Detailed project walk-thru conducted with PUC, NDOT and City staff. Project successfully designed and completed under budget on an expedited schedule.
