BACKGROUND AND DISCUSSION
This year marks the 43rd Annual Kaiser Permanente Napa Valley Marathon, scheduled to take place on Sunday, March 6, 2022. The course begins on Silverado Trail at Rosedale Lane in Calistoga, and runs along Silverado Trail from Calistoga to Oak Knoll Avenue, Oak Knoll Avenue from Silverado Trail to Big Ranch Road, Big Ranch Road from Oak Knoll Avenue to El Centro Avenue, El Centro Avenue from Big Ranch Road to the Napa City Limits and continuing on to the finish at Vintage High School in Napa. In addition to the full marathon, a half marathon will begin at Conn Creek Winery and finishing at Vintage High School following the same route as the marathon. Participants will park at Vintage High School where they will be transported by buses to the start of the marathon and half marathon. There have been no reported problems or complaints associated with previous years' events.
For public and participant safety, the organizers have requested road closures to facilitate running the 26.2 miles with the least amount of inconvenience to the public. All traffic control and road closures will be under the direction of the California Highway Patrol (CHP), with a rolling closure in effect for southbound traffic. Runners will have the full width of Silverado Trail for the first 12 miles from Calistoga to State Highway 128. Silverado Trail will be closed to southbound traffic from State Highway 128 to Yountville Crossroad. CHP will escort any vehicles traveling north on Silverado Trail to their destination(s) in small groups, at reduced speeds, to insure safety for the race participants. Silverado Trail will then be closed from Yountville Crossroad to Oak Knoll Avenue between the hours of 7:00 A.M. and 1:30 P.M. and Oak Knoll Avenue from Silverado Trail to Big Ranch Road, Big Ranch Road from Oak Knoll Avenue to El Centro Avenue, El Centro Avenue from Big Ranch Road to the Napa City Limits and continuing on to the finish at Vintage High School in Napa. In the event of an emergency, CHP is present to modify/stop the event as needed to accommodate the particular situation.
The aid station located at the nine-mile mark (intersection of Silverado Trail at Pope Street in St.Helena) will be staffed with one doctor, one nurse, and one physical therapist. Aid stations are roughly 2.5 miles apart and communication will be through the use of cell phones and HAM radio operations at these locations. The medical center, located at the finish area, will be staffed with at least 3 doctors, two nurses, two physical therapists, and twelve podiatric students and an advisor. A physical therapist center will be located adjacent to the Vintage High School cafeteria where several physical therapists will be on duty.
Public Works has included conditions to ensure a safe environment for the public. These conditions are:
A. All traffic control devices and personnel be in conformance with Caltrans' Traffic Manual;
B. All properties having access to Silverado Trail, Oak Knoll Avenue, Big Ranch Road, and El Centro being closed shall be notified prior to the event and access shall be provided to them during the event;
C. Access shall be provided for emergency vehicles at all times;
D. The organizers of the Kaiser Permanente Napa Valley Marathon shall contract with the CHP for traffic control services during the event;
