In October 1993, a series of major brush fires ravaged Southern California. The Kinneola Mesa fire scorched more than 5,700 acres in the San Gabriel Mountains, leaving several major watersheds barren. The watersheds serve the foothill communities of Altadena, Pasadena and Sierra Madre. Without vegetation, these communities were at high risk for catastrophic mudslides during the rainy winter months. The disastrous fire created a unique opportunity to quickly rehabilitate the Pasadena-Glen Watershed and restore it back to its natural state. The primary concern of the Forest Preservation Society of California was to restore the watershed's ability to collect and percolate rainfall, since each acre foot restored means substantial savings to the state by reducing the need to import water.
