out its review of certain proposals for general plans, specific plans, zoning
ordinances, and certain land use development proposals near the Travis AFB
for compatibility with aircraft operations at the Base.
Compatibility Zone C encompasses locations exposed to potential noise in
excess of approximately 60 decibel (dB) Community Noise Equivalent Level
(CNEL) together with additional areas occasionally affected by concentrated
numbers of low‐altitude aircraft overflights.
The compatibility criteria defined by the policies are also intended to be
reflected in the general plans and other policy instruments adopted by the
entities having jurisdiction over land near Travis AFB. Specifically, the
Travis AFB LUCP affects and requires action by the County and Cities in the
County.
Compatibility Zone D includes all other locations beneath any of the
Travis AFB airspace protection surfaces delineated in accordance with
Federal Aviation Regulation (FAR) Part 77 as well as areas subject to
frequent aircraft overflight.
The LUCP was last adopted in October 2015, an update to the previous 2002
plan. The updated plan was needed to ensure consistency with the policies
and standards set by the Solano County ALUC Review Procedures and the
California Department of Transportation (Caltrans) 2011 California Airport
Land Use Planning Handbook. The update also addresses compatibility
issues associated with renewable energy projects and assault landing zone
operations. Compatibility Zone E includes the area located between Zone D and the
Travis AFB AIA boundary, which is coterminous with the Solano County
boundaries.
Compatibility Zones The Height Review Overlay Zone covers locations where the terrain
exceeds or comes within 35 feet of any of the FAR Part 77 airspace
protection surfaces for Travis AFB.
The ALZ Training Overlay Zone is based on the combat arrival and
departure simulations that occur at a minimum elevation of 500 feet Above
Ground Level (AGL).
The Travis AFB LUCP establishes six compatibility zones ‐ A, B1, B2, C, D, and
E ‐ as well as two overlay zones ‐ the Assault Landing Zone (ALZ) Training
Overlay Zone and the Height Review Overlay Zone.
Each compatibility zone and overlay zone have specific requirements and
regulations, such as maximum densities and intensities (indoor, outdoor,
and single acre intensity), uses that are prohibited within the given zone,
and additional development conditions. These regulations are separated
into General Standards, Noise Criteria, Safety Criteria, Airspace Protection
Criteria, and Avigation Easement Dedication.
Compatibility Zone A consists of the Travis AFB runways, together with
immediately adjoining areas within the runway primary surface and clear
zones.
Compatibility Zone B1 comprises APZ I.
Compatibility Zone B2 is comparable to APZ II but is expanded to
encompass approach and departure flight tracks that are not aligned with
the runway.
