Noise abatement also touches on Sponsor Assurance regarding land use compatibility. Which assurance is this?

• A. Sponsor Assurance #21, compatible land use
• B. Grant Assurance #22, economic nondiscrimination
• C. Assurance #5 Preserving Rights and Powers
• D. Assurance #19 Operations and Maintenance

Answer: (A)

Noise abatement is about keeping aircraft noise from creating incompatible conditions for nearby land uses. The Sponsor Assurance that directly addresses this is the one requiring Compatible Land Use. This assurance obligates the sponsor to work with local authorities to plan and enforce land use around the airport so that development is compatible with aviation operations and noise levels—often including noise abatement programs, land use restrictions near the airport, and notification or mitigation measures when new development could be affected.

The other assurances cover different topics: economic nondiscrimination deals with fair treatment in grant-funded benefits, preserving rights and powers protects the sponsor’s legal authority, and operations and maintenance focuses on maintaining and operating facilities.
