Since 2005, Irvine Ranch Conservancy has been managing Bommer Canyon for the City of Irvine by restoring the natural habitat and developing community programs for visitors to enjoy. The land in Bommer Canyon was acquired in the early 1800’s by a man named Don Jose Sepulveda. In 1864, the land was then sold to Flint Bixby & Co. and their silent partner, James Irvine. Soon after, Irvine bought out his partners and took ownership of the land that became known as Rancho San Joaquin, Rancho Los Lomas de Santiago, Rancho Santiago de Santa Ana and eventually Bommer Canyon.
