Project Description

Green Valley Consulting Engineers performed the Construction Management and Inspection for both phases of this Federally-funded $3 million dollar resurfacing project which rehabilitated just over one-and-a-quarter-miles of Rohnert Park Expressway (RPX) – a primary east/west, four-lane arterial. Project limits extended westward from Snyder Lane to Commerce Boulevard (located adjacent to the Highway 101 interchange) and involved work in three major 4-way intersections, including the City’s busiest and most collision-prone. Altogether, the project involved 4,000 SY of dig-out repairs, structural pavement modifications, day, nighttime, and weekend paving operations, utility adjustments, concrete curb and gutter, ADA ramp, and median curb replacements, new colorized bike lanes, new pavement striping/markings/markers, the installation of GridSmart (camera) intersection traffic management systems, and the rehabilitation of the City Library’s parking lot. Followed Caltrans and City Standards & Requirements.

Maintaining pedestrian-safe, ADA-compliant, and one-lane vehicular access was paramount in this multi-use (school/government/commercial/residential) area which experiences heavy pedestrian and vehicular traffic. Daily communication – from cone up to cone down – kept the City’s Dept. of Public Safety informed of all lane/road closures and changes throughout the day. Additional challenges included providing uninterrupted emergency vehicle access along the corridor, maintaining access to the Library, local businesses, and three major shopping centers, working within a couple hundred yards of Highway 101, and coordinating with adjacent projects (SMART Rail, Snyder Lane Widening, and Petaluma Hill Road Pavement Preservation – 2016, County of Sonoma).
