City of Reno Sewer and Street Rehabilitation

DOWL completed the design and construction management for the roadway rehabilitation of neighborhood streets in central Reno including Stewart Street, Taylor Street, Gould Street, and Dayton Way. The street rehabilitation included the reconstruction of 1.3 miles of roadway, the replacement of curb and gutter, portions of sidewalk, residential and commercial driveways, and pedestrian ramps. A 27-inch sewer interceptor was installed in the project area in conjunction with the roadway improvements.

DOWL performed land surveying, data collection and mapping of existing utilities, AutoCAD Civil 3D grading design, construction staking, and construction management for this project. A special assessment district (SAD) for sidewalk improvements in the project area was prepared to assist the city with property assessments and communications with homeowners. Pavement rehabilitation included pulverization of the existing pavement and base, cement treatment of the base, and two lifts of hot mix asphalt. The roadway design was challenging due to low existing cross slopes and low flow line slopes. Creative solutions such as superelevation of the roadway and defined variable height curb helped solve these design challenges. In addition, DOWL re-aligned an intersection near the Libby Booth Elementary School that provided more direct pedestrian crossings to increase pedestrian safety. During construction there were several challenges, one of which was shallow gas utilities. DOWL was able to coordinate efficiently with NV Energy to lower shallow gas mains and services to allow for roadway pulverization.
