Noise Mitigation Project

RMMA is surrounded by residential development. Located only 3 miles south of Louisville, aircraft overflights and noise are a growing concern for residents. Flight operations at RMMA have been increasing over the last 5 years and this growth is expected to continue. Louisville has partnered with Superior to hire a consulting team with specialized experience in working with communities and airports to address aircraft noise issues. The consultants will review current conditions, flight procedures, airspace and land uses around RMMA to identify practices and procedures aimed at reducing impacts to both communities.

The project focuses on four task areas:

  • Assessment of current conditions
  • Community engagement
  • Industry engagement
  • Strategy development

Project Status

The summary below provides the status for each task to date:

  • Task 1 - Baseline assessment
    • The baseline assessment is currently underway. We expect to complete this in spring 2019. The baseline assessment will help assess and understand current conditions and help identify opportunities for improvement. The consultants will look at airport facilities and airfield layout, airspace and flight procedures, annual operations, traffic levels and fleet mix, the existing noise abatement program, land uses and zoning around the airport and review complaint data and community concerns. You can read the draft baseline assessment here.
  • Task 2 - Community engagement  
  • Task 3 - Industry engagement
    • The consulting team has had multiple meetings with the airport and FAA traffic control tower personnel. A flight training forum was also held in February. The event was intended to engage industry stakeholders and encourage participation the process. A number of initiatives and strategies were identified for reducing noise impacts. An industry advisory group was established to keep this effort moving forward.
  • Task 4 - Strategy development
    • The consultants will work with our partner stakeholders to develop a list of short, medium and long-term strategies intended to reduce noise impacts on the community. The consultants will also develop an education and outreach program to encourage ongoing collaboration with industry partners like the airport and FAA and expand awareness of the new noise program and to encourage compliance.
