The city of Irvine has prepared an initial study mitigated negative declaration to analyze the potential environmental effects associated with the proposed roadway widening project along Jamboree Rd, Main to Barranca. Jamboree Rd is a significant roadway to the city's Irvine Business Complex, which is a major employment hub serving surrounding communities within the city of Irvine and the county of Orange. The proposed roadway widening will add a fifth northbound through lane and a fifth southbound through lane on Jamboree Rd, Main St to Barranca Parkway, from approx 2,000 ft south of Main St to approx 2,000 ft north of Barranca Parkway to improve the existing level of service along Jamboree Rd. The overall length of the project study area along Jamboree Rd is approx 1.2 miles. The project would acquire land on both sides of the existing roadway by widening the same distance from the existing roadway centerline. Construction activities along the road segments include construction of concrete curbs and gutters, curb ramps, concrete sidewalks. Asphalt Rubber Hot Mix, Filtera Box Systems, catch basins, local depressions, and resurfacing of slurry seal type.
