If any portion of the GreenBelt is used during an event, the organizer must provide a map of the route from start to finish. Please see below to calculate how many Police Officers and EMS may be needed. Please describe the route (start, finish location, direction, any stops or aid stations along the route, and so on). These Police/EMT fees must be paid on the day of the event by the Renter. If Emergency/Police personnel are needed, their fees are calculated at $50 per person per hour. Police Department: at least one officer is needed per street crossing (2 hours minimum). Fire Department: two EMT’s are required at all times during the event (2 hours minimum).
