Task 1 - Establish Project Committees
A Technical Advisory Committee (TAC) and a Policy Advisory Committee (PAC) will be established and utilized throughout the FAR Part 150 Noise Compatibility Program Update to regularly review study progress and provide input. The committees will be comprised of individuals representing:

The TAC will receive regular briefings and provide input. Periodic, scheduled meetings to discuss project progress and findings will be conducted at appropriate project milestones.

The consultant will meet with City/Department of Aviation staff to develop guidelines for committee size, structure, and membership, and will assist in drafting a letter inviting participation. The consultant will also assist to determine meeting schedule and locations. Mailings, meeting arrangements, and attendance lists will be the responsibility of the City/Department of Aviation staff.

A Community Advisory Committee (CAC) would also be established at the outset of the project to ensure adequate public involvement. The CAC would include representatives of local realty agencies, neighborhood organizations, and citizens from impacted communities.

Task 2 - Inventory 

2A. Airport Traffic Operations Activity
Collect data on scheduled air carrier, commuter/air taxi, general aviation, air cargo, and military aircraft activity to determine existing (1999) operations. 

2B. Land Use Mapping and Land Development Trends
Obtain current land use maps from local jurisdictions and United States Geological Survey (USGS) Quadrangle Maps for use in creating basemaps for noise exposure contour exhibits. Obtain aerial photographs for the area within the existing noise exposure area. Meet with the Miami Valley Regional Planning Commission, Montgomery County Planning Commission, Miami County Planning Commission; representatives from Vandalia, Englewood, Huber Heights, Union, and Dayton; and public officials from other local jurisdictions to review anticipated growth and development patterns in the area around the Airport. Assemble reports and maps from those organizations which identify future land use and development trends in the anticipated noise exposure area.

Task 3 - Review and Update Aviation Demand Forecasts
Review forecasts of scheduled air carrier, commuter/air taxi, general aviation, air cargo, and military aircraft activity contained in the draft Master Plan Update, and update as necessary. 

Summaries of aircraft activity for the average day of the year for existing (1999) and forecast five-
year (2005) conditions by aircraft and engine type, departure trip length and time of day of operation will be developed. In addition, forecasts will be prepared for a 20-year horizon (2018). Because 2003 is the final extended deadline for compliance with the National Noise Policy and the phase-out of Stage 2 aircraft, it is expected that aircraft noise exposure in the vicinity of the airport will lessen in the coming years regardless of any growth in aircraft operations that occurs at the Airport. However, as the number of aircraft operations conducted at the airport continues to increase in the future, it is probable that the aircraft noise exposure area will grow. 

In order to ensure long-term land use compatibility in the airport environs, it is recommended that a noise exposure map be prepared for 2018. Long-term future aircraft noise exposure is a concern of the FAA and it is likely that the changes to the FAR Part 150 currently being drafted by the FAA will include a requirement for a long-term noise exposure map. 

Task 4A - Gather and Analyze Automated Radar Terminal Systems (ARTS) Data from the Air Traffic Control Tower
If available, Automated Radar Terminal System (ARTS) radar tracking data will be obtained from the FAA's Air Traffic Control Tower. This information, which provides valuable input to aircraft noise analyses, details actual flight tracks (location, speed, and altitude) and aircraft identification and type, recorded in real-time for each aircraft arriving and departing the Airport. The information can be extracted in a digital format and translated into input for INM noise modeling. 

Noise measurements and ARTS data will be used to create input for and validate the results of INM noise modeling. Using this information, aircraft noise levels, approach parameters, and profile data can be developed for an individual aircraft class to more accurately depict noise levels. Validation of the model will ensure that the computer analysis accurately reflects actual noise generation.

Task 4B - Gather and Analyze Noise Data From Field Measurements 
 Field measurements of noise will be made to help validate the Integrated Noise Model (INM). This will be accomplished by installing portable noise monitoring units in the field on a temporary basis. Measurements will be taken for about two weeks, from instruments placed in sample locations within the day-night average sound level (DNL) 65 contour or under flight tracks. The R&A Team will work with the Airport Noise Officer and property owners to determine suitable locations, make the installations, and conduct the monitoring. Information collected for each noise monitoring site would include DNL and single-event noise levels measured using the sound exposure level (SEL) metric. Ambient noise levels (background noise without aircraft) will also be documented from this task.

Noise measurements and ARTS data will be used to create input for and validate the results of INM noise modeling. Using this information, aircraft noise levels, approach parameters, and profile data can be developed for an individual aircraft class to more accurately depict noise levels. Validation of the model will ensure that the computer analysis accurately reflects actual noise generation.

Task 5 - Prepare Aircraft Noise Exposure Maps
Prepare necessary data and assumptions for input into the INM. Using the INM, prepare aircraft noise exposure maps (NEMs) for existing (1999) and forecast (2005 and 2018) conditions. Noise exposure contours will be drawn to show DNL 60, 65, 70, and 75 exposure areas. These contours will be superimposed over maps of existing and planned land use, United States Geological Survey (USGS) Quadrangle Maps, and aerial photographs. Airport runways, the Airport boundary, and jurisdictional boundaries will be depicted on the noise exposure maps. Information regarding noise-sensitive land uses within the areas exposed to DNL 60, 65, 70, and 75, including the location of noise-sensitive facilities which have already received acoustical treatment, will be documented on the NEMs.

Task 6 - Determine Effects of Aircraft Noise Exposure on Land Use and Population
Estimate the effects of aircraft noise exposure on land areas within the various DNL contours, including effects to noise-sensitive land uses and people. Quantify the number of residential units as well as the population exposed to significant levels of aircraft noise. Identify noise-sensitive land uses which have received acoustical treatment. In addition, identify areas that experience an increase of 1.5 decibels (dBA) within the DNL 65 and higher contour in accordance with published FAA criteria. The consideration of an increase of 3.0 dBA within the DNL 60 to 65 contour will likewise be identified as "significant" impact in accordance with recently published FAA criteria

Task 7 - Prepare Noise Exposure Map Report
Prepare twenty-five (25) copies of a draft Noise Exposure Map (NEM) report on the updated noise exposure maps for James M. Cox-Dayton Municipal Airport. The report will include a description of the methodology used to develop the noise exposure contours as well as all of the other information required under FAR Part 150. The noise exposure map for the base year will be considered final at this point. The future (2005 and 2018) noise exposure maps, which will be prepared assuming current operating procedures, will be considered preliminary. Future conditions maps would be subject to modification as a result of recommendations that might be made in the update to the Noise Compatibility Program (NCP). 

Following a review by the TAC and the receipt of comments from the public, twenty-five (25) copies of the 1998 baseline Noise Exposure Map report will be prepared and submitted to the FAA for its approval.

Task 8 - Review Potential Noise Abatement Measures
In addition to reviewing the noise abatement measures already in effect at the Airport and those identified in the existing NCP, identify any additional alternative actions that could be taken to reduce aircraft noise exposure in the Airport environs. Lists of the actions considered and those that warrant further evaluation will be prepared. 

Based on the Airport's 5-year CIP, the 2005 Noise exposure map (NEM) will reflect the extension of northeast/southwest Runway 6R-24L. The 2018 NEM (not an official map) will reflect the development of the proposed north parallel runway. Specific noise abatement measures may be identified for implementation with these improvements. Noise grid maps will be prepared to compare DNL levels for the various noise abatement scenarios analyzed. Grid cells used in the noise grid analysis will be approximately 23 acres in size (1,000 feet per side).

Task 9 - Evaluate and Select Noise Abatement Measures
Establish the criteria and methodology to be used in evaluating alternative noise abatement measures. The criteria should include factors such as:

Each measure identified in the previous task for further evaluation will be assessed according to these criteria. In accordance with the evaluation and review, recommend noise abatement measures for inclusion in the NCP Update.

Task 10 - Revise Aircraft Noise Exposure Maps
Using the recommended noise abatement measures, modify, if necessary, the input to the INM and revise the aircraft noise exposure maps for 2005 and 2018. Determine the effect of the revised future aircraft noise exposure conditions on both existing and planned land use.

Task 11 - Review and Update Existing Noise Mitigation Measures
Review the recommended policies and programs to achieve noise mitigation included in the existing NCP and verify their continued applicability to the Airport environs. Document implementation dates, performance determination metrics, and reporting procedures for each measure. Determine any changes to the boundaries applicable to specific programs as a result of the updated noise exposure maps. Identify any additional measures that might apply. 

Task 12 - Evaluate and Select Noise Mitigation Measures
 Recommend both the criteria and the methodology to be used in evaluating noise mitigation measures, including input from the Department of Aviation and the TAC. Using the established criteria and methodology, evaluate the noise mitigation measures. If appropriate, prepare cost estimates and cost/benefit analyses as part of the evaluation of the mitigation measures.

In accordance with the evaluation and review, select the noise mitigation measures to be recommended for inclusion in the NCP Update.

Task 13 - Prepare Draft Noise Compatibility Program Update Report
 Prepare twenty-five (25) copies of a draft report and submit for review by the Department of Aviation and the TAC.

Task 14 - Conduct Public Hearing
 Conduct a formal public hearing to obtain official comments from concerned public and Airport users regarding the NCP Update. 

Task 15 - Prepare Final and Summary Reports
 Following review and comments by the Department of Aviation, the TAC, the FAA, concerned public, and others at the public hearing, prepare twenty-five (25) copies of the final report for submission and approval by the FAA. In addition, five hundred (500) copies of a summary report will also be prepared. One set of reproducibles for each document will also be provided to the Department of Aviation. The consultants can also assist the Department of Aviation in development of an updated public information flyer and other materials, if necessary.

Task 16 - Conduct a Community Involvement Process Concurrent with the Study
Establish a community involvement process that encourages continuous dialogue among all parties of interest and creates opportunities for maximum input from the general public. The community involvement process would begin long before the public hearing, and would involve the Department of Aviation, the TAC, the consultants, special interest groups (such as neighborhood associations), and the general public. 

The community involvement process will generally consist of the following elements:

Committee meetings will be conducted by the project team on a regular basis as indicated above to brief committee members on the progress and findings of the study. In addition, special briefings will be conducted in advance of each public forum and the public hearing.

Public information forums and workshops will be held to provide public education about aircraft noise and the study process and to solicit input from the general public. These could consist of formal presentations, guided displays, breakout sessions, and roundtable discussions. A minimum of two public information forums will be held prior to the public hearing. These forums will be coordinated with public officials from the impacted districts to afford those individuals and their constituents ample opportunity to be involved.

In addition, a maximum of five small group or individual briefings will be conducted prior to the public forums/workshops and a public hearing for key groups or individuals such as the Planning Commission and local public officials.

At a minimum of thirty (30) days prior to the formal public hearing, announcements will be placed in all local newspapers and copies of the draft final report will be distributed to various City, Township and County departments, libraries, and the Airport. Locations where the report will be made available for public review will be listed in the newspaper announcements.

Unless otherwise requested by the Department of Aviation, the public hearing will only be held to receive verbal and written comments, and will be conducted in accordance with FAA requirements, including a formal transcript of the proceedings. If the Department of Aviation requests a presentation before receiving comments, this portion of the public hearing would not be part of the transcript and not part of the hearing itself. The formal portion of the public hearing will be called to order and commence after completion of the presentations. Such a presentation is optional and not required by the FAA.
