body
Summary
The State Highway 99 Widening project included new traffic signals on Mariposa Road at the intersections with South 99 Frontage Road West and Stagecoach Road. Segments of each intersection are within the City and San Joaquin County (County) jurisdictions. The City has two of the three legs of the intersection at South 99 Frontage Road West and one of the three legs at Stagecoach Road (Attachment A - Vicinity Map). All similar traffic signals with shared City/County responsibility are operated and maintained by the City, with the County reimbursing the City for their share of the costs. The recommended agreement applies this standard cost sharing arrangement to the new Mariposa Road traffic signals.
DISCUSSION
Background
City and County staff coordinate and participate in transportation projects that affect both City and County areas. This coordination results in cost savings, reduces duplication of efforts, and produces a more uniform transportation system in areas that transition back and forth between the two jurisdictions.
One such area is the operation, maintenance, interconnection, and coordination of traffic signals throughout the Stockton metropolitan area. Since a number of roadways such as Mariposa Road, Arch Road, Hammer Lane, Eight Mile Road, and Pershing Avenue transition back and forth between City and County jurisdiction, there are numerous signalized intersections that have joint responsibility. The City is the lead agency on operation and maintenance of these signals, with the County providing reimbursement for their share of the cost in accordance with the maintenance agreements for each signal.
Present Situation
The State Highway 99 Widening project included new traffic signals at Mariposa Road and Stagecoach Road, and at Mariposa Road and South 99 Frontage Road West. Segments of each intersection are within the City and County jurisdictions. The traffic signals were activated in November 2016.
Currently, the City controls two legs of the South 99 Frontage Road West or 67 percent of this three-legged intersection, with the County controlling the remaining leg or 33 percent of the intersection. At Stagecoach Road, the City controls one leg or 25 percent of this four-legged intersection, with the County controlling the remaining three legs or 75 percent of the intersection.
As is standard practice, the City will take the lead on the maintenance and operation of the two new traffic signals. The County is responsible for a portion of the cost of this maintenance. Costs are allocated based on the number of intersection legs in each jurisdiction. The recommended agreement establishes that the County will reimburse 33 percent of the cost of the Frontage Road signal, and 75 percent of the cost of the Stagecoach Road signal. Once this agreement is approved by Council, County staff will take the agreement to the Board of Supervisors for approval.
FINANCIAL SUMMARY
The maintenance of the traffic signal systems will be included as part of the routine traffic signal maintenance performed by Public Works Operations and Maintenance. The City will invoice the County for the shared costs of the maintenance, operation, and energy on a quarterly basis. There are sufficient funds in Public Works Operating budget (030-3065-540 and 082-3065-540) to perform traffic signals maintenance. The estimated cost to maintain one traffic signal is approximately $4,000 annually. Based on the above cost sharing, the County’s share will be $4,320 annually for the two traffic signals. The cost will fluctuate depending on the actual cost of electricity and the maintenance required.
