Items we need!


Our mission is to provide the continuation and preservation of an equestrian arena at the Radke-Martinez Regional Shoreline Park. This arena was managed by Martinez Horsemenís Association for many years providing a public arena and a location for local equestrians to participate in horse shows, clinics, playdays, etc.

Martinez Horsemenís Association has disbanded and they have terminated the Special Use Agreement they held with East Bay Regional Park District for the arena property and have liquidated their assets on the property.

Tri-Cities Horsemenís Association has partnered with EBRPD to keep the arena going! If this arena was allowed to close, we would not get it back and another equestrian facility would have been lost. We have assumed the remaining property lease with EBRPDís blessing. They are enthusiastic with our plans to promote the arena and encourage more use of this great location.

Anticipated Outcomes:

By ensuring the continuation of the public arena, local equestrians will have a place to ride, train and compete in activities in the future. The general public will be exposed to horses, many of which have never seen or touched an actual horse. We will be ambassadors that can explain about the importance of horses in our history and their impact, and besides, kids love horses!

Participating Community Groups, Volunteers:

Our members are the main source of volunteers to erect the arena. If you would like to help please let us know!

Fund Raisers:

We are planning fund raisers for the arena rebuild and ongoing expenses.
