The Santa Ana River is the largest river system in Southern California and it flows to the southwest in an arc from the San Bernardino Mountains to the ocean at Huntington Beach. Since 1915, when the idea for a recreational trail paralleling the river originated, the watershed has been under relentless encroachment by urban growth. Despite this pressure, the vision of the trail has grown as well. Its supporters now embrace the concept of a recreational parkway: The Santa Ana River Trail (SART). When complete the trail will serve multiple uses by providing public access into open space areas that can withstand human activity such as hiking, bicycling, equestrian use, camping, environmental education, and health and fitness. Additionally its supporters plan to provide interpretation of the Inland Empire's rich history and natural environment. Ultimately, the trail will parallel the river from its headwaters at the Pacific Crest Trail to its mouth at the Pacific Ocean at Huntington Beach.

The purpose of this study served to create a geographical database to improve data access and analysis capabilities for research from all entities (governmental agencies, advocacy groups, etc) involved with the SART planning process. Before the creation of this geodatabase there was no centralized method for accessing this data. The geodatabase can serve as a planning aid for the various parties involved with the Santa Ana River Trail project.
