BACKGROUND: For many years, ingress and egress to the College Park West community has been negatively impacted by traffic using the westbound on /off ramp for SR 22. This roadway is a multi - jurisdictional freeway off -ramp operated by Caltrans and located in the City of Long Beach. The City of Seal Beach desires to see improvements to the intersection at the entrance and exit to College Park West. This intersection also serves a neighborhood in the City of Long Beach. The intersection is located at College Park Drive and the SR 22 westbound Studebaker Road on /off ramp in the City of Long Beach. As residents of Seal Beach and Long Beach exit from College Park Drive, which terminates at the SR 22 off -ramp, the residents must stop until it is safe to proceed. College Park Drive,and the SR 22 off -ramp is a stop controlled "T" intersection. At various times of the day, including the morning, noon and evening peak hours, vehicles wait an inordinate amount of time to exit from these residential areas due to the continuous stream of vehicles coming on and off the freeway. There is no concern for local Long Beach residents because they have an alternative exit through their tract. The City of Long Beach restricts access for Seal Beach residents to this alternative during the most critical times by way of a right turn prohibition at Salida Avenue. Agenda Item 0 Page 2 On December 8, 2008, the City Council approved an agreement to employ Willdan Engineering to provide concept drawings to present to Caltrans, Long Beach and OCTA. Staff has met with Caltrans District 7 and 12, OCTA and City of Long Beach. All are understanding of the situation and are supportive of our efforts to make improvements. Since the subject location is in Caltrans District 7, the City of Seal Beach needs the support of District 7 for any improvements made to this intersection. From Caltrans direction, the City must gather additional traffic data and provide two concept designs, one with a roundabout intersection and one signalized with left turn phasing. On November 7, 2009, City staff held a community meeting at Edison Park to review various alternatives for improving the entrance /exit to College Park West. The project is located at the "T" intersection of College Park Drive and the 22 Freeway westbound off ramp. The City's consultant, Willdan Engineering, has prepared a draft traffic study and intersection improvement exhibits which incorporated the November 7, 2009 community meeting comments. A copy of the draft traffic study is available at the Mary Wilson Library and the City Clerk's Office. The draft traffic study developed four possible options to improve vehicular access from College Park Drive to the SR -22 freeway ramps. As the analysis progressed, Options 1A and 1B were added to the study. The six options are described below. Option 1 $899,175 Install a traffic signal at the intersection of the SR -22 Ramps and College Park Drive. Option 1A $1,179,525 Install a traffic signal at the intersection of the SR -22 Ramps and College Park Drive, and widen the SR -22 Off -Ramp from one lane to two lanes between the SR -22 Freeway and College Park Drive. Option 1B $1,105,800 Install a traffic signal at the intersection of the SR -22 Ramps and College Park Drive, and widen the SR -22 Off -Ramp from one lane to two lanes between the SR -22 Freeway and College Park Drive, making the second lane a northbound right turn only lane onto' College Park Drive. Option 2 $448,125 Modify the intersection of the SR -22 Ramps and College Park Drive to provide an acceleration lane on the westbound on -ramp for motorists making left turns from College Park Drive, provide a free -right turn lane from College Park Drive to the offramp, and provide a left turn lane from the on -ramp onto College Park Drive. Page 3 Option 3 $1,537,687 Limit access from College Park Drive to right turns only onto the SR -22 Ramps and allow U -turns at the SR -22 Ramps and Studebaker Road to provide a way for motorists on College Park Drive to access the on -ramp and get on the freeway going westbound. Option 4 $1,432,237 Construct a roundabout at the intersection of the SR -22 Ramps and College Park Drive. Each option was analyzed through a computer simulation called Synchro., The simulation applied real world data and traffic volumes to verify the efficiency and workability. The simulation also looked at queuing of vehicles during rush hour times and how far back ups that may occur. The computer simulation resulted with Option 1A which appears to be the most efficient option to provide relief for the residents and improve the overall operation of the intersection, with a cost in the mid -range of the options. FINANCIAL IMPACT: There is no financial impact at this time. RECOMMENDATION: It is recommended City Council adopt Resolution No. 5986 selecting Option 1A from the Traffic Study Report for Proposed Improvements to College Park Drive at SR -22 Ramps and Studebaker Road and receive and file said report.
