Deputy Marshals are law enforcement officers that patrol the parks, green spaces, and surrounding areas to ensure the safety of park patrons.
Deputy Marshals also work in the municipal court as bailiffs and warrant officers. Bailiff duties include providing security for the municipal court. Warrant officer duties include delivering subpoenas and serving municipal warrants.
Many parks and trails have a unique marking system. Parks and trails have a letter designation such as RV for Rio Vista Park and a number system to indicate your location. If you need assistance, look for a sign or pole marker such as RV22 and report that location to dispatch.
