Document Description
The proposed Project entails minor widening and lane restriping of the intersection at Culver Drive and Alton Parkway, within the City of Irvine, including the following improvements: • Adding a fourth northbound through lane on Culver Drive; • Removing the southbound free right turn lane on Culver Drive and converting it to a standard right turn lane; and removal of the existing pedestrian island; • Adding a southbound right turn overlap phasing on Culver Drive coordinated with the eastbound dual left turn phasing on Alton Parkway (prohibiting eastbound U-turn movement); • Extending the eastbound and westbound left turn pockets in both directions on Alton Parkway approaching the intersection at Culver Drive; • Adding concrete bus pads at existing bus stops located at the northeast (Culver Drive), northwest (Alton Parkway) nearest the retail business at 3755 Alton Parkway, currently occupied by Olive Garden Italian restaurant, and southeast (Alton Parkway) corners of the intersection; • Adding a new bus stop and bus pad on the northwest corner (Alton Parkway) of the intersection nearest to the retail business at 3995 Alton Parkway, currently occupied by Starbucks coffee shop; • Modify / improve supporting traffic signal, medians, sidewalks, and landscaping, where applicable and; • Providing enhanced striping to the existing on-street bike lanes on all four (4) legs of the intersection. Additional roadway improvements include signage, traffic signals, streetlights, utility relocations, drainage and water quality improvements, retaining walls, landscape, and lighting. The proposed Project is one of the mitigations identified in both 2010 and 2015 Irvine Business Complex (IBC) Vision Plan Traffic Studies and would improve circulation in both the short- and long-term to the intersection by providing capacity enhancements and improve circulation.
