Airport Runway Protection Zone and Inner Safety Zone

THIS LAYER IS OWNED AND MAINTAINED BY LOS ANGELES COUNTY VIA THE LA COUNTY OPEN DATA PORTAL Runway Protection Zone (RPZ): A trapezoidal area at ground level (formerly called a clear zone) extending from the end of a runway and centered on the extended centerline of the runway. Its purpose is to provide a safe, clear space for aircraft takeoffs and approaches, and to protect people and property on the ground. Please click here to see the Los Angeles County Airport Land Use Commission portion of our website for maps and documents. You can also refer to the California Airport Land Use Planning Handbook for further information (see Figure 9K – Safety Compatibility Zone Examples; RPZs are shown as Zone 1 in the diagrams). Inner Safety Zone (ISZ - also referred to as “Inner Approach / Departure Zone"): The areas located at the ends of runways, immediately after and sometimes alongside the RPZs. Please refer to the California Airport Land Use Planning Handbook for further information (see Figure 9K – Safety Compatibility Zone Examples; ISZs are shown as Zone 2 in the diagrams). SOURCE: Los Angeles County Airport Land Use Plan (adopted 1991 / revised 2004); Brackett Field Land Use Compatibility Plan (adopted 12/9/15).
