The Los Angeles County Flood Control District's (LACFCD) core responsibilities are to provide flood protection and water conservation in over 3,000 square miles within the County of Los Angeles. To achieve this and effectively serve the residents of the county, the LACFCD owns, operates and maintains a number of major dams, debris basins, open channels, underground storm drains, catch basins, spreading grounds, and sea water barrier projects among other facilities, and the associated rights of way. As such, in order to protect these investments by ensuring their integrity is preserved while accommodating the needs of future development, and pursuant to Los Angeles County Code, any work, encroachment, or activity within or affecting the LACFCD right-of-way, facilities, interests or jurisdiction requires a Flood Control Permit.
