CHAPTER 3 Existing and Future Airport and Environs Conditions 3.1 Existing Airport Facilities SFO is located approximately 13 miles south of downtown San Francisco in unincorporated San Mateo County and the active operations area is bordered by the San Francisco Bay to the east, Interstate 380 (I-380) to the north, and U.S. 101 to the west and south. Of the 5,100 acres that comprise Airport property, approximately 2,110 acres are located on land east of U.S. 101, 180 acres are not actively used for Airport operations and are located west of U.S. 101, and 2,810 acres are San Francisco Bay tidal waters. As shown on Exhibit 3-1, the Airport is surrounded by the cities of Millbrae and Burlingame (to the south), San Bruno (to the west), and South San Francisco (to the north). Other jurisdictions in the vicinity of SFO include: the City of Brisbane, the Town of Colma, Daly City, the City of Pacifica, the Town of Hillsborough, the City of San Mateo, Foster City, and San Mateo County (i.e., unincorporated areas). Direct access to the terminal buildings and parking facilities is provided by ramps directly from U.S. 101. Other landside facilities at SFO are accessible from North Access Road (via U.S. 101 and I-380 ramps) and San Bruno Avenue (via U.S. 101 ramps). Existing facilities at SFO are presented on Exhibit 3-2 and summarized in the following sections. 3.1.1 Airfield Facilities Airport Runways There are four runways at SFO: Runway 10L-28R is 11,870 feet long and 200 feet wide; Runway 10R-28L is 11,381 feet long and 200 feet wide; Runway 1L-19R is 7,650 feet long and 200 feet wide; and Runway 1R-19L is 8,650 feet long and 200 feet wide. Runway data are summarized in Table 3-1. Taxiways A system of taxiways and taxilanes at SFO is designed to connect the four runways to the passenger terminal complex, air cargo aprons, fixed based operators (FBOs), and general aviation facilities. Each of the four runways has a full-length taxiway. Runways 28R and 19L have angled taxiways to expedite aircraft exiting the runways after landing.

Existing and Future Airport and Environs Conditions This page intentionally left blank San Francisco International Airport 3-4 ESA / 120832 14 CFR Part 150 Noise Exposure Map Report August 2015 3. Existing and Future Airport and Environs Conditions 3.1.2 Passenger Terminal Facilities The SFO terminal complex is located on the east side of the Airport, and has a series of seven boarding areas, Boarding Areas A through G, that are divided into three domestic terminals and one international terminal. 3.1.3 Airport Traffic Control Tower The Airport is serviced by an active FAA airport traffic control tower (ATCT) located in the vicinity of Terminal 2. The ATCT operates 24 hours a day, 365 days a year. Radar approach and departure control is operated by the Northern California Terminal Radar Approach Control (NORCAL TRACON) located in Mather, California. 3.1.4 Other Facilities General Aviation Facilities General aviation includes all facets of aviation excluding military, air cargo, and scheduled passenger service. Some of the major categories of general aviation include corporate operations, air taxi operations, flight training, and traffic monitoring. The single FBO at SFO is located north of the end of Runway 10L, and is operated by Signature Flight Support. The facility offers services to general aviation aircraft including: aviation fuel, terminal and lounge, aircraft parking, maintenance hangers, and pilot services. Air Cargo Facilities Air cargo and maintenance facilities at SFO are located on the north side of the Airport along North McDonnell Road. United Airlines and the United State Parcel Service have facilities north of the terminal complex. FedEx Express also uses apron and sorting facilities on the north side of the Airport. Other Aviation-related facilities A number of aviation-related support facilities are located on airport property. These facilities include: • Aircraft Rescue and Firefighting Facility (ARFF) • Aircraft Fueling Facilities • Airport Ground Service Maintenance Facility • Rental Car Facilities • Customs and Border Protection • Airport Police San Francisco International Airport 3-6 ESA / 120832 14 CFR Part 150 Noise Exposure Map Report August 2015 3. Existing and Future Airport and Environs Conditions 3.2 Future/Planned Airport Facilities The Airport Commission is currently constructing a new ATCT at SFO and the Runway Safety Area (RSA) Project is nearing completion. Other planned improvements at SFO that will be constructed prior to 2019 include: (1) an on-Airport hotel; (2) Terminal 3 Modernization; (3) Terminal 1 Redevelopment; (4) South Field Buildings Demolition; and (5) Long Term Parking Garage Development. The airport layout plan that was conditionally approved by the FAA in June 2014 is shown on Exhibit 3-3. None of these projects is anticipated to have an impact on aircraft operations (i.e., number and type of aircraft) at SFO. Future runway characteristics data for SFO are provided in Table 3-2. 3.3 Navigational Aids SFO employs several navigational aids, airport lighting, and airport markings to help users of the Airport safely navigate around the Airport and SFO airspace. The navigational aids include: Instrument Landing Systems (ILS), Localizer Type Directional Aid (LDA), Area Navigation (RNAV)/Global Positioning Systems (GPS), and a VOR/DME which is the combination of a Very High Frequency (VHF) Omni-Directional Range (VOR) and Distance Measuring Equipment (DME). A glossary of terms is provided in Chapter 6 of this report. The Localizer Type Directional Aid is of comparable use and accuracy to a localizer but is not part of a complete ILS. An LDA approach is not aligned with the runway for either operational or other reason such as terrain. The LDA approach allows the approach course to be offset so that there is enough spacing for approach to both parallel runways to be conducted at the same time when visibility permits.1 Straight-in minimums may be published where alignment does not exceed 30 degrees between the course and runway. The GPS uses a network of satellites that create reference points to enable aircraft equipped with GPS receivers to determine their latitude, longitude, and altitude. GPS systems can be used by aircraft during all phases of flight. Area Navigation or RNAV is a method of navigation that permits aircraft operation on any desired flight path using the combination of both GPS and ground-based navigational aids. RNAV routes and terminal procedures, including departure procedures and standard terminal arrivals, are designed with RNAV systems in mind to save time and fuel, reduce aircraft dependence on air traffic control (ATC) vectoring, and provide for more efficient use of the 1 Runways at SFO are spaced 750 feet measured from runway centerline to parallel runway centerline, which is insufficient for the critical design aircraft to conduct simultaneous operations utilizing the runways during inclement weather conditions.
