Modification of the San Diego Class B Airspace Area; CA

This action modifies the San Diego, CA, Class B airspace area. Specifically, this action lowers the upper limit of the San Diego Class B airspace area from 12,500 feet mean sea level (MSL) to 10,000 feet MSL; expands the western and eastern boundaries of the airspace area; and moves the southern boundary north to align with the POGGI Very High Frequency Omnidirectional Range Tactical Air Navigation (VORTAC). The FAA is taking this action to enhance safety, reduce the potential for midair collision, and to improve the management of air traffic operations into, out of, and through the San Diego Class B airspace area, while accommodating the concerns of airspace users.
