Sports Fields

Union City residents and visitors love sports and active, open spaces. In addition to the many parks throughout Union City, we maintain and manage 20 different sports fields permitted for public use.


Reserving Sports Fields

Want to reserve a sports field? Residents can reserve sports fields for events up to three calendar months in advance, and nonresidents can reserve sports fields up to two calendar months in advance. You must make your reservation at the Mark Green Sports Center in person at least 10 working days before your scheduled event (two-week notice).


In order to reserve a sports field, groups must complete a Ball Field/Sports Field Facility Use Permit Application (PDF). All groups must provide the city with a $1 million liability insurance policy with the City of Union City named as additionally insured.


For more information on group priority or permit period sessions, please download a copy of our Ball Field Use Policy and Procedures (PDF). All applications or requests must be submitted in person at:
