Vice-Chairperson: MARK ADDIEGO Representative, City of South San Francisco [email protected]

Welcome


The Airport/Community Roundtable was established in May 1981, by a Memorandum of Understanding (MOU), to address noise impacts related to aircraft operations at San Francisco International Airport (SFO). The Airport is owned and operated by the City and County of San Francisco, but it is located entirely within San Mateo County. This voluntary committee consists of 22 appointed and elected officials from the City and County of San Francisco, the County of San Mateo, and several cities in San Mateo County (see attached Membership Roster). It provides a forum for the public to address local elected officials, Airport management, FAA staff, and airline representatives, regarding aircraft noise issues. The committee monitors a performance-based aircraft noise mitigation program, as implemented by Airport staff, interprets community concerns, and attempts to achieve additional noise mitigation through a cooperative sharing of authority brought forth by the airline industry, the FAA, Airport management, and local government officials. The Roundtable adopts an annual Work Program to address key issues. In 2017, the Roundtable is scheduled to meet on the first Wednesday of the following months: February, April, June, August, October and December. Regular Meetings are held on the first Wednesday of the designated month at 7:00 p.m. at the David Chetcuti Community Room at Millbrae City Hall, 450 Poplar Avenue, Millbrae, California unless noted. Special Meetings and workshops are held as needed. The members of the public are encouraged to attend the meetings and workshops to express their concerns and learn about airport/aircraft noise and operations. For more information about the Roundtable, please contact Roundtable staff at (650) 363-1853.

POLICY STATEMENT

The Airport/Community Roundtable reaffirms and memorializes its longstanding policy regarding the “shifting” of aircraft-generated noise, related to aircraft operations at San Francisco International Airport, as follows:

“The Airport/Community Roundtable members, as a group, when considering and taking actions to mitigate noise, will not knowingly or deliberately support, encourage, or adopt actions, rules, regulations or policies, that result in the “shifting” of aircraft noise from one community to another, when related to aircraft operations at San Francisco International Airport.” (Source: Roundtable Resolution No. 93-01)

FEDERAL PREEMPTION, RE: AIRCRAFT FLIGHT PATTERNS

The authority to regulate flight patterns of aircraft is vested exclusively in the Federal Aviation Administration (FAA). Federal law provides that:

“No state or political subdivision thereof and no interstate agency or other political agency of two or more states shall enact or enforce any law, rule, regulation, standard, or other provision having the force and effect of law, relating to rates, routes, or services of any air carrier having authority under subchapter IV of this chapter to provide air transportation.” (Source: 49 U.S.C. A. Section 1302(a)(1)).

Glossary of common Acoustic and Air Traffic Control

terms AADS-B - Automatic Dependent Surveillance – Broadcast – ADS-B uses ground based antennas and in-aircraft dis-plays to alert pilots to the position of other aircraft relative to their flight path. ADS-B is a key element of NextGen.

Air Carrier - A commercial airline with published schedules operating at least five round trips per week.

Air Taxi – An aircraft certificated for commercial service available for hire on demand.

ALP - Airport Layout Plan – The official, FAA approved map of an airport’s facilities.

ALS – Approach Lighting System - Radiating light beams guiding pilots to the extended centerline of the runway on final approach and landing.

Ambient Noise Level – The existing background noise level characteristic of an environment.

Approach Lights – High intensity lights located along the approach path at the end of an instrument runway. Approach lights aid the pilot as he transitions from instrument flight con-ditions to visual conditions at the end of an instrument ap-proach.

APU - Auxiliary Power Unit – A self-contained generator in an aircraft that produces power for ground operations of the electrical and ventilation systems and for starting the en-gines.

Arrival – The act of landing at an airport.

Arrival Procedure - A series of directions on a published approach plate or from air traffic control personnel, using fix-es and procedures, to guide an aircraft from the en route en-vironment to an airport for landing.

Arrival Stream – A flow of aircraft that are following similar arrival procedures.

ARTCC – Air Route Traffic Control Center - A facility providing air traffic control to aircraft on an IFR flight plan within controlled airspace and principally during the enroute phase of flight.

ATC - Air Traffic Control - The control of aircraft traffic, in the vicinity of airports from control towers, and in the airways between airports from control centers.

ATCT – Air Traffic Control Tower - A central operations tower in the terminal air traffic control system with an associ-ated IFR room if radar equipped, using air/ground communi-cations and/or radar, visual signaling and other devices to provide safe, expeditious movement of air traffic.

Avionics – Airborne navigation, communications, and data display equipment required for operation under specific air traffic control procedures.

Altitude MSL –Aircraft altitude measured in feet above mean sea level.

BBackblast - Low frequency noise and high velocity air gener-ated by jet engines on takeoff.

Base Leg – A flight path at right angles to the landing run-way. The base leg normally extends from the downwind leg to the intersection of the extended runway centerline.

CCenter – See ARTCC.

CNEL – Community Noise Equivalent Level - A noise metric required by the California Airport Noise Standards for use by airport proprietors to measure aircraft noise levels. CNEL includes an additional weighting for each event occurring dur-ing the evening (7;00 PM – 9:59 PM) and nighttime (10 pm – 6:59 am) periods to account for increased sensitivity to noise during these periods. Evening events are treated as though there were three and nighttime events are treated as thought there were ten. This results in a 4.77 and 10 decibel penalty


penalty for operations occurring in the evening and nighttime periods, respectively.

CNEL Contour - The "map" of noise exposure around an airport as expressed using the CNEL metric. A CNEL con-tour is computed using the FAA-approved Integrated Noise Model (INM), which calculates the aircraft noise exposure near an airport.

Commuter Airline – Operator of small aircraft (maximum size of 30 seats) performing scheduled (maximum size of 30 seats) performing service between two or more points.

DDecibel (dB) - In sound, decibels measure a scale from the threshold of human hearing, 0 dB, upward towards the threshold of pain, about 120-140 dB. Because decibels are such a small measure, they are computed logarithmically and cannot be added arithmetically. An increase of ten dB is perceived by human ears as a doubling of noise.

dBA - A-weighted decibels adjust sound pressure towards the frequency range of human hearing.

dBC - C-weighted decibels adjust sound pressure towards the low frequency end of the spectrum. Although less con-sistent with human hearing than A- weighting, dBC can be used to consider the impacts of certain low frequency oper-ations.

Decision Height – The height at which a decision must be made during an instrument approach either to continue the approach or to execute a missed approach.

Departure – The act of an aircraft taking off from an airport.

Departure Procedure – A published IFR departure proce-dure describing specific criteria for climb, routing, and com-munications for a specific runway at an airport.

DME - Distance Measuring Equipment - Equipment (airborne and ground) used to measure, in nautical miles, a slant range distance of an aircraft from the DME navigation-al aid.

DNL - Day/Night Average Sound Level - The daily aver-age noise metric in which that noise occurring between 10:00 p.m. and 7:00 a.m. is penalized by 10 dB. DNL is often expressed as the annual-average noise level.

DNL Contour - The "map" of noise exposure aroundan airport as expressed using the DNL metric. A DNL con-tour is computed using the FAA-approved Integrated Noise Model (INM), which calculates the aircraft noise exposure near an airport.

Downwind Leg – A flight path parallel to the landing runway in the direction opposite the landing direction.

Duration - The length of time in seconds that a noise event lasts. Duration is usually measured in time above a specific noise threshold.

EEn route – The portion of a flight between departure and arrival terminal areas.

Exceedance— Whenever an aircraft overflight produces a noise level higher than the maximum decibel value estab-lished for a particular monitoring site, the noise threshold is surpassed and a noise exceedance occurs. An exceedance may take place during approach, takeoff, or possibly during departure ground roll before lifting off.

FFAA - The Federal Aviation Administration is the agency responsible for aircraft safety, movement and controls. FAA also administers grants for noise mitigation projects and approves certain aviation studies including FAR Part 150 studies, Environmental Assessments, Environmental studies, Environmental Assessments, Environ Impact Statements, and Airport Layout Plans.

RNAV – Area Navigation - A method of IFR navigation that allows an aircraft to choose any course within a network of navigation beacons, rather than navigating directly to and from the beacons. This can conserve flight distance, reduce congestion, and allow flights into airports without beacons.

RNP – Required Navigation Performance - A type of performance-based navigation (PBN) that allows an air-craft to fly a specific path between two 3- dimensionally de-fined points in space. RNAV and RNP systems are funda-mentally similar. The key difference between them is the requirement for on- board performance monitoring and alerting. A navigation specification that includes a require-ment for on-board navigation performance monitoring and alerting is referred to as an RNP specification. One not hav-ing such a requirement is referred to as an RNAV specifica-tion.


Run-up – A procedure used to test aircraft engines after maintenance to ensure safe operation prior to returning the aircraft to service. The power settings tested range from idle to full power and may vary in duration.

Run-up Locations - Specified areas on the airfield where scheduled run-ups may occur. These locations are sited, so as to produce minimum noise impact in surrounding neigh-borhoods.

SSequencing Process – Procedure in which air traffic is merged into a single flow, and/or in which adequate separa-tion is maintained between aircraft.

Shoreline Departure – Departure via Runways 28 that uti-lizes a right turn toward San Francisco Bay as soon as fea-sible. The Shoreline Departure is considered a noise abate-ment departure procedure.

SENEL – Single Event Noise Exposure Level - The noise exposure level of a single aircraft event measured over the time between the initial and final points when the noise level exceeds a predetermined threshold. It is important to distin-guish single event noise levels from cumulative noise levels such as CNEL. Single event noise level numbers are gener-ally higher than CNEL numbers, because CNEL represents an average noise level over a period of time, usually a year.

Single Event – Noise generated by a single aircraft over-flight.

SOIA – Simultaneous Offset Instrument Approach Is an approach system permitting simultaneous Instrument Landing System approaches to airports having staggered but parallel runways. SOIA combines Offset ILS and regular ILS definitions.

Terminal Airspace - The air space that is controlled by a TRACON.

Terminal Area – A general term used to describe airspace in which approach control service or airport traffic control service is provided.

Threshold – Specified boundary.

TRACON -Terminal Radar Approach Control – is an FAA air traffic control service to aircraft arriving and de-parting or transiting airspace controlled by the facility. TRA-CONs control IFR and participating VFR flights. TRACONs control the airspace from Center down to the ATCT.

U

VVector – A heading issued to a pilot to provide navigational guidance by radar. Vectors are assigned ver-bally by FAA air traffic controllers.

VFR – Visual Flight Rules are rules governing procedures for conducting flight under visual meteorological conditions, or weather conditions with a ceiling of 1,000 feet above ground level and visibility of three miles or greater. It is the pilot’s responsibility to maintain visual separation, not the air traffic controller’s, under VFR.

Visual Approach – Wherein an aircraft on an IFR flight plan, operating in VFR conditions under the control of an air traffic facility and having an air traffic control authori-zation, may proceed to destination airport under VFR.

VASI – Visual Approach Slope Indicator - An airport lighting facility in the terminal area navigation system used primarily under VFR conditions. It provides vertical visual guidance to aircraft during approach and landing, by radiat-ing a pattern of high intensity red and white focused light beams, which indicate to the pilot that he/she is above, on, or below the glide path.

VMC – Visual Meteorological Conditions - weather conditions equal to or greater than those specified for air-craft operations under Visual Flight Rules (VFR).

VOR - Very High Frequency Omni-directional Range – A ground based electronic navigation aid transmit-ting navigation signals for 360 degrees oriented from mag-netic north. VOR is the historic basis for navigation in the national airspace system.

Regular Meeting Overview / Meeting No. 308 August 2, 2017 Page 2 of 4 2. Introduction, Roundtable Technical Consultant – HMMH (Justin Cook) Roundtable Chairperson Elizabeth Lewis introduced Justin Cook of HMMH, part of the consultant team serving the Roundtable. 3. Public Comments on Items NOT on the Agenda A total of seven member of the public spoke during public comments. Pacifica resident Ahna Dominski expressed the need for better data on the number of aircrafts flying over cities, as well as the need for easier reporting methods/applications. Pacifica resident Ken Miles praised the airport director for his attendance and attentiveness at prior meetings to concerns raised by residents. Hillsborough resident Sally Meakin mentioned appreciation for the help she’s received from the Noise Abatement Office and the need of easier reporting methods. South San Francisco resident Doreen Gotelli spoke on the need of a noise insulation retrofit repair fund. Roger Miles, Town of Hillsborough resident, rasied concern over the FAA orders to use Runway 1L/R that is causing an increase in backblast noise. Pacifica resident Julie Duffy spoke on the difficulty in reporting noise events, and has stopped doing do. San Francisco resident Charlie Wambeke indicated that noise is still impacting his neighborhood. 4. Review of Roundtable Regular Meeting Overview for June 7, 2017. ACTION: Ann Schneider MOVED approval of meeting overview for June 7, 2017. The motion was seconded by Ricardo Ortiz and CARRIED, unanimously. 5. Review of Airport Director’s Reports for May and June 7, 2017 6. Review of SFO FlyQuiet Report for Q2 2017 7. Airport Director’s Comments Roundtable Chairperson Lewis indicated that items five, six, and seven would be consolidated and addressed by SFO’s Public Information Officer Doug Yakel. Mr. Yakel provided an overview of how the airport will handle updates and report briefings during Roundtable meetings that focused on data overview, actions and mitigation, and airport activities updates. Mr. Yakel mentioned that SFO’s decision to move forward with the installation of a Ground-Based Augmentation System (GBAS), SFO would like to present to the Roundtable an overview of GBAS at the next regular meeting. Roundtable members asked several questions of the reports and presentations Mr. Yakel mentioned during his presentation. Mr. Yakel indicated that SFO was open to modifications that the Roundtable was felt more meaningful and useful for the group. It was clarified that the data reflective in the illustrations are complaints per city, and perhaps it should be discussed as a group as to how to calculate/collect complaints (standalone versus consolidated) as was raised by some members. Additional comments and concerns were raised regarding the value of a “heat-map” of complaints. Chairperson Lewis noted that this is a work in progress, and it’s important for the airport to show us what they’re developing and then the Roundtable can provide feedback as to what to add or subtract.


Regular Meeting Overview / Meeting No. 308 August 2, 2017 Page 3 of 4 8. Status, FAA Initiative Response Roundtable Chairperson Elizabeth Lewis asked Kathleen Wentworth of Congresswoman Speier’s office to provide any update she may have for the Roundtable. Ms. Wentworth indicated that the latest from the FAA estimates a late fall arrival of the final draft of the FAA Initiative Phase 2 document, and read a statement provided from the Congresswoman on the matter. Chairperson Lewis provided a summary of the current Phase 2 document that was released in late July, and indicated the Roundtable’s Technical Working Group would be discussing the matter on August 15th. Montara resident Viviana Guzman commented on the impacts of overflights in her community and pleaded that the plans be rerouted back to the way they used to. Leslie Ransbottom of Save Our Skies East Bay read a letter submitted earlier to the Roundtable that spoke on the potential impacts to East Bay communities from recommendations included in the response to the FAA Initiative, and encourage the Roundtable to work with those impacted East Bay cities.

Fly Quiet Report


Fly Quiet Program San Francisco International Airport’s Fly Quiet Program is an Airport Community Roundtable initiative implemented by the Aircraft

Noise Abatement Offi ce. Its purpose is to encourage individual airlines to operate as quietly as possible at SFO. The program

promotes a participatory approach in complying with noise abatement procedures and objectives by grading an airline’s

performance and by making the scores available to the public via newsletters, publications, and public meetings.

Fly Quiet offers a dynamic venue for implementing new noise abatement initiatives by praising and publicizing active participation

rather than a system that admonishes violations from essentially voluntary procedures.

Program Goals The overall goal of the Fly Quiet Program is to infl uence airlines to operate as quietly as possible in the San Francisco Bay Area. A

successful Fly Quiet Program can be expected to reduce both single event and total noise levels around the airport.

Program Reports Fly Quiet reports communicate results in a clear, understandable format on a scale of 0-10, zero being poor and ten being good.

This allows for an easy comparison between airlines over time. Individual airline scores are computed and reports are generated

each quarter. These quantitative scores allow airline management and fl ight personnel to measure exactly how they stand

compared to other operators and how their proactive involvement can positively reduce noise in the Bay Area.

Program Elements Currently the Fly Quiet Program rates jets and regional jets on six elements : the overall noise quality of each airline’s fl eet operating

at SFO, an evaluation of single overfl ight noise level exceedences, a measure of how well each airline complies with the preferred

nighttime noise abatement runways, assessment of airline performance to the Gap and Shoreline Departures, and over the bay

approaches to runways 28L and 28R.


SFO’s Fly Quiet RatingsFleet Noise Quality The Fly Quiet Program Fleet Noise Quality Rating evaluates the noise contribution of each airline’s fl eet as it actually operates at SFO. Airlines generally own a variety of aircraft types and schedule them according to both operational and marketing considerations. Fly Quiet assigns a higher rating or grade to airlines operat-ing quieter, new generation aircraft, while airlines operating older, louder technology aircraft would rate lower. The goal of this measurement is to fairly compare airlines—not just by the fl eet they own, but by the frequency that they schedule and fl y particular aircraft into SFO.

Noise Exceedance Eliminating high-level noise events is a long-standing goal of the Airport and the Airport Community Round-table. As a result the Airport has established single event maximum noise level limits at each noise-monitor-ing site. These thresholds were set to identify aircraft producing noise levels higher than are typical for the majority of the operations.

Whenever an aircraft overfl ight produces a noise level higher than the maximum decibel value established for a particular monitoring site, the noise threshold is surpassed and a noise exceedance occurs. An exceed-ance may take place during approach, takeoff, or possibly during departure ground roll before lifting off. Noise exceedances are logged by the exact operation along with the aircraft type and airline name.

Nighttime Preferential Runway Use SFO’s Nighttime Preferential Runway Use program was developed in 1988. Although the program cannot be used 100% of the time because of winds, weather, and other operational factors, the Airport, the Com-munity Roundtable, the FAA, and the Airlines have all worked together to maximize its use when conditions permit. The program is voluntary; compliance is at the discretion of the pilot in command. The main focus of this program is to maximize fl ights over water and minimize fl ights over land and populated areas between 1:00 a.m. and 6:00 a.m. Fortunately, because airport activity levels are lower late at night, it is feasible to use over-water departure procedures more frequently than would be possible during the day. Reducing night-time noise—especially sleep disturbance— is a key goal of SFO’s aircraft noise abatement program.

Shoreline Departure Quality Aircraft departing SFO using Runways 28L and 28R are also considered by the Fly Quiet grading system whenever they use the Shoreline Departure Procedure. This predominately VFR (visual fl ight rules) depar-ture steers aircraft to the northeast shortly after takeoff in an attempt to keep aircraft and aircraft noise away from the residential communities located to the northwest of SFO. By keeping aircraft east of Highway 101 the majority of the overfl ights will be experienced by industrial and business parks instead of residential areas.

In order to evaluate each airline’s performance when fl ying a Shoreline Departure, a corridor was established using Interstate 101 (green colored fl ight tracks) as a reference point. The corridor runs north along 101, beginning approximately one-mile north-northwest of the end of Runways 28L and 28R and continuing up into the City of Brisbane. Departures west of 101 are scored marginal or poor depending on their location.

Gap Departure Quality Aircraft departing SFO using Runways 28L and 28R frequently depart straight out using a procedure known as the Gap Departure. This procedure directs air traffi c to fl y a route that takes them over the area northwest of the airport over the cities of South San Francisco, San Bruno, Daly City, and Pacifi ca. In an attempt to miti-gate noise in this specifi c area, the Gap Departure Quality Rating has been included as a category in the Fly Quiet Program.

Since “higher is quieter”, aircraft altitudes are recorded along the departure route. Scores are assigned at specifi ed points or gates set approximately one mile apart, with the higher aircraft receiving higher scores.

Foster City Arrival QualityThe Arrival Quality Rating is the latest addition to the Fly Quiet Program. In an effort to further reduce night-time noise in neighboring communities, this rating is designed to maximize over-bay approaches to Run-ways 28 between 11:00 p.m. and 6:00 a.m. Airlines arriving to Runways 28 during these hours are assessed based on which approach fl ight path was used. Over-the-bay approaches are rated good (green colored fl ight tracks), versus over-the-communities which are rated poor.

MEMORANDUM

TO: BRISBANE COMMUNITY

FROM: SAN FRANCISCO INTERNATIONAL AIRPORT AIRCRAFT NOISE ABATEMENT OFFICE

SUBJECT: 3Q 2017 BRISBANE NOISE MONITORING REPORT

DATE: NOVEMBER 27, 2017

The San Francisco International Airport (SFO) Aircraft Noise Abatement Office conducts aircraft noise monitoring in the City of Brisbane, California to determine noise levels within the community from aircraft operations at SFO. Noise monitoring occurs every quarter for a 14-day data collection period. This quarter’s measurement period was from July 26, 2017 to August 8, 2017. The monitoring is made possible with the assistance of the City Manager and School Superintendent, resulting in two temporary sites in Brisbane. The first site, Site 966 was located at The Mission Blue Center and the second site, Site 988 was located at Lipman Middle School. The overall average daily noise level from all aircraft at Site 966 was 46 A-weighted decibels (dBA) Community Noise Equivalent Level (CNEL), and at Site 988 the aircraft CNEL was 52dBA. The Community daily noise level at Site 966 was 54dBA CNEL and at Site 988, it was 55dBA. Noise from all aircraft increased the total average daily noise level by 1.2dBA at Site 966 and 1.6dBA at Site 988. SFO aircraft comprised 95% of all aircraft noise events over Site 966 and 80% over Site 988. During the monitoring period, SFO had two weekends (July 29-30 and August 5-6) where departures from Runways 01L/R (Left/Right) were suspended due to construction work. All departures utilized Runways 28L/R during this closure. This caused a decrease in flights over Site 966 and increased the amount of flights over Site 988 due to aircraft using the TRUKN and NIITE departure procedures. Non-aircraft noise sources included residential noise, vehicular traffic, and wind noise. Brisbane is located approximately 4 miles from the airport. The city typically experiences aircraft utilizing the SSTIK and OFFSHORE departure procedures. Aircraft departing SFO from Runways 01L/R for destinations to the west, south and southeast typically overfly Brisbane. Occasionally when the winds on the airfield are stronger from the west, the TRUKN OR NIITE departures will be utilized for destinations to the east. Departing aircraft from Runways 28L/R will initiate a right turn once the aircraft reaches the minimum altitude of 520 feet, consequently this may have some aircraft fly over Brisbane. SFO traffic arriving from the north on the BDEGA, STINS or GOLDEN GATE arrival on a typical day (West Plan) overfly Brisbane at 10,000 feet or higher. The ambient levels within Brisbane during the monitoring period were as follows: Site 966 - 49dBA and Site 988 - 50dBA. On an average day, Site 966 had 451 overflights. 6% exceeded the noise monitor thresholds and recorded a noise event. The threshold was set at 65dBA for the monitoring period. Site 988 had 465 overflights, 38% exceeded the noise monitor threshold and recorded a noise event. The threshold was set at 55dBA for the monitoring period. During the noise-monitoring period, SFO Aircraft Noise Abatement Office received noise reports from 36 individuals in Brisbane. Majority of aircraft noise events at Site 966 occurred between 11am and 7pm. At Site 988 it was between 7am and 6pm. On average, there were only 5 nighttime noise events at Site 966 and 27 nighttime events at Site 988. In view of the fact that the monitoring locations in Brisbane are located in a suburb with ambient noise of 50dBA, any aircraft noise above this threshold may become a nuisance for the residents. dBA- stands for A-weighted decibel. Decibel unit measures the loudness of a sound and is computed as the signal to noise ratio. A-weighting is used to adjust for frequency range of human hearing. An increase of ten decibels is perceived by human ear as a doubling of noise. SEL - Sound Exposure Level of a noise event is measured over time between the initial and final points when the noise level exceeds a predetermined threshold and its energy is compressed into one second. LMax - The maximum noise level is a measurement of the peak level of a noise event. CNEL- This metric is used to assess and regulate aircraft noise exposure in communities surrounding the airport. California Title 21 Noise Regulations established acceptable level of aircraft noise of 65dBA CNEL. West Plan – Standard operations at the Bay Area International Airports. Aircraft arrive to the west at all three airports. At San Jose and Oakland Airports, aircraft depart to the west. While at San Francisco Airport, aircraft depart either to the north or to the west depending on wind conditions on the airfield. TRUKN and NIITE – RNAV departure procedures off Runways 28L/R at SFO, has aircraft climb heading of 284° to 520 feet then right turn to initial fix. These procedures replaced the legacy departures procedures SHORELINE and QUIET, respectively.

MEMO RANDU M

TO: MONTARA COMMUNITY

FROM: SAN FRANCISCO INTERNATIONAL AIRPORT AIRCRAFT NOISE ABATEMENT OFFICE

SUBJECT: MONTARA SHORT-TERM NOISE MONITORING REPORT

DATE: OCTOBER 23, 2017

The San Francisco International Airport (SFO) Aircraft Noise Abatement Office conducted aircraft noise monitoring in Montara to determine the noise levels within the community from aircraft operations at SFO. The monitoring was made possible with the assistance of a Montara resident. The overall average daily noise level from all aircraft was 42dBA CNEL. The Community daily noise level was 51dBA CNEL. Noise from all aircraft over this location increased the total average daily noise level by 1dBA. SFO aircraft attributed 60% of all aircraft noise events over Montara community. During the noise monitoring period there were no weather or other impacts that would cause delays, require use of reverse flow or alter the flight patterns in any way. Non-aircraft noise sources included dogs barking.

Montara is a quiet suburban community with ambient noise levels of 48dBA. On an average day, Montara had 155 overflights out of which 65 exceeded the noise monitor threshold of 51dBA and recorded a noise event. Flights departing SFO bound for destination airports in the south or southeast; will turn left over the peninsula and continue their path south using a published departure procedure or as directed by Federal Aviation Administration Air Traffic Controllers. As these flights overfly parts of coastal communities they represent 60 percent of all aircraft noise events over Montara, and are typically at or above 10,000 feet. Oakland departures add additional 10 percent to these flights. About 30 percent of aircraft noise events over Montara is low-flying general aviation traffic heading to Half Moon Bay Airport or transitioning to the smaller aviation airports such as San Carlos and Palo Alto. An average sound exposure level (SEL) for a single noise event for all aircraft were recorded at 71dBA and maximum noise levels (LMax) at 58dBA. SFO and Oakland aircraft have lower LMax and SEL levels and are quieter than the general aviation traffic as they overfly the area about 8,000 feet higher. During the noise monitoring period SFO Aircraft Noise Abatement Office received noise reports from six individuals in the Mid-Coast communities. Majority of aircraft noise events occurred between 9am and 9pm, and on average, there were only four nighttime noise events. In view of the fact that the monitoring location in Montara is located in a quiet suburban community with ambient noise in the quiet 40dB range, any aircraft noise above this threshold may become a nuisance for the residents.

dBA- stands for A-weighted decibel. Decibel unit measures the loudness of a sound and is computed as the signal to noise ratio. A-weighting is used to adjust for frequency range of human hearing. An increase of ten decibels is perceived by human ear as a doubling of noise. SEL - Sound Exposure Level of a noise event is measured over time between the initial and final points when the noise level exceeds a predetermined threshold and its energy is compressed into one second. LMax - The maximum noise level is a measurement of the peak level of a noise event. CNEL- This metric is used to assess and regulate aircraft noise exposure in communities surrounding the airport. California Title 21 Noise Regulations established acceptable level of aircraft noise of 65dBA CNEL.
