What is a CSO? 

Hillsborough River State Park Preservation Society, Inc. is a volunteer Citizen Support Organization (CSO), which was founded in 1993. This volunteer, nonprofit, citizen-support organization was formed to generate public awareness, education, and financial support for the preservation and maintenance of Hillsborough River State Park and the Fort Foster State Historic Site.

Like Florida State Parks, the Hillsborough River State Park and the Fort Foster State Historic Site have programs and needs which reach beyond the state’s ability to provide funding and support. This is where the Preservation Society comes in. By generating additional support for the park in the form of fundraising, supplemental staffing, equipment, etc., we are aiding the park in the fulfillment of it’s mission.

The Hillsborough River State Park Preservation Society, Inc. is a non-profit organization under section 501(c)(3). All donations are tax-deductible to the fullest extent of the law under section 501(c)(3) of the Internal Revenue Code.
