Review of February 24Review of February 24thth WorkshopWorkshop

Held at Mt. Rainier High School in Des Moines- Approximately 150 people attended- Began with a presentation on Part 150 - 15 Breakout stations where people were invited to provide direct input to assist in refining the scope

- Breakout summary provided instant feedback- Ended with a Q&A session

Breakout Session SummaryBreakout Session SummaryWays to Reduce Noise

• Limits on Cargo• Deal with Runups• New ways to fund mitigation outside 65 DNL• Better community planning effort• Increase altitudes on arrival• Curfews on flights• Noise Berms/vegetation• Buyout or sales assistance• Sound insulation• Move airport• Implement noise abatement• Insulation by homeowners• Quieter aircraft at night• Hush house• Home improvements the Port can make• Share more information about new technology• New monitors for 3rd runway• Transparency about 3rd runway• Flight scheduling during nighttime• Better advertising of outreach events• Place tax on nighttime passengers• Look at taxiway exits• Allowing data collected to be shared with Port/airlines• Insulating to 55 DNL

Review of February 24Review of February 24thth WorkshopWorkshop

Feedback on Main Concerns- What concerns people - What information they want to come from the Study- Suggestions on ways to reduce noise- Ways to better communicate with them

Action Items- Developed a Meeting Summary- Reviewing the input to determine what can or can’t be implemented and reporting back to the public

- Publish on the website and discuss at the next workshop (June 9th)

Feedback on Meeting Format- Overwhelmingly positive- Later start time and increase advertising/notification

Existing Conditions: - Scenario 1: Actual 2009 Conditions

- Combination of 2 and 3 runway configurations- Represents what actually occurred during 2009

- Scenario 2: 2009 Extrapolated 3 Runway Configuration- Represents what would have happened in 2009 with a 3

runway configuration- Provides a better indication of what the ‘typical’ operating

mode will be

Future Baseline Conditions:- 2016 Operating levels and aircraft types- Other factors, such as location of flight tracks and how

often each runway is used, will be the same as existing- Provides a 3 runway baseline with future operating levels to

begin developing ways to reduce noise.

Existing Conditions: - Source: Calendar year 2009 data from Airport Noise and

Operations Monitoring System (ANOMS) and FAA- Annual Operations: 318,600 (873 average annual day)- Fleet Mix:

- Boeing 737 “Next Gen” are the most common aircraft- Boeing 747-400 is the largest aircraft

Future Baseline Conditions:- Forecast of Aviation Activity underway- Will include changes in operating levels and fleet mix

Flight Tracks: - Source: Flight track data of a typical day from ANOMS• North Flow• South Flow• Three-Runway• Two-Runway- Analysis: 2009 flight tracks will be analyzed for location

and flight density by various aircraft types- Initial Findings:

- The majority of aircraft are following the existing noise abatement procedures

- Early turns on departure are being conducted by smaller turbo-propeller aircraft

Runway Use: - Source: Runway use data in yearly percentage used from

ANOMS- Analysis: 2009 runway use will be analyzed for various

conditions- Day versus night- By aircraft type- By north versus south flow- By 2 runway versus 3 runway conditions

- Initial Findings: - South flow (arrivals from the north and departures to the

south) is the predominant flow at the airport (approx. 69% in 2009)

- When 3 runways were available, the runway use was consistent with projections from the Third Runway EIS

- When 2 runways were available, Runway 16R/34L was used approximately 40% of the time

- Monitors 1 & 2 are used to capture noise from run-ups- DNL is a yearly average

Monitors 1 and 2 are on the airfield

Baseline Data:Baseline Data: Measured Single Event Noise LevelsMeasured Single Event Noise LevelsNoise Levels:

- Source: ANOMS• Lmax is the highest noise level measured during a flyover• Scale is constant• There are 25 total permanent sites• The following shows a sample of the data collected at 4 sites- Findings: Noise levels will depend on NMT location

relative to flight pattern

Supplemental Measurement Program: - Part 150 will conduct monitoring at up to 12 additional sites

- Purpose of the program is to augment the 25 permanent sites- Sideline propagation and topographic effects

- Anticipated schedule is Summer 2010- Two sites are dedicated to ground/run up noise west of

airport- Up to ten sites to address public comments and concerns

- Gather technical data to support the modeling- Responding to specific concerns brought up by the public that

are not already covered by one of the 25 permanent sites- Results of the programs will be shared

- TRC- Public- Website

Provide input on the following:1. Questions/Comments about the public

workshops?2. Are there other data sources that we should

utilize to supplement what we have already?3. Suggestions for noise measurement locations

or conditions?4. Suggestions for improving the way we are

displaying/presenting data?
