As part of the City’s on-call program, Civil Works Engineers prepared a Project Report and an Environmental Document for widening alternatives at the Jamboree Road / Main Street intersection. The project involved the identification and preliminary development of numerous widening alternatives after performing a traffic analysis study. The preferred project improvements were identified to include adding a fifth northbound and southbound through lane on Jamboree Road, removing the free right turns on Main Street, and installing controlled dual right turns. The widening will impact adjacent commercial, residential and hotel properties plus an OCFCD drainage channel. Right-of-way acquisition and modifications to the private property improvements were also required. We performed coordination with Caltrans because the intersection is within the influence of the I-405 Jamboree Road ramps.
