Welcome to the Lihue Airport (LIH)

Master Plan and Part 150 Noise Exposure Map Updates

The State of Hawaii Department of Transportation – Airports Division (HDOT-A) is updating the 1989 Lihue Airport Master Plan and 1991 Part 150 Noise Exposure Map and Noise Compatibility Study.

The Master Plan Update will reflect new facilities, current forecasts of aviation activity and new environmental and other regulatory constraints, and plan for the appropriate mix of land uses to support projected aviation and non-aviation needs.

The Part 150 Noise Exposure Map Update will also reflect current and forecast operations at LIH.

The HDOT-A welcomes your participation and feedback.

What is an Airport Master Plan?

An Airport Master Plan is a process that comprehensively studies the short, intermediate, and long-term development needs of an airport and develops plans to meet aviation demand considering potential environmental and socioeconomic impacts.

What is a Part 150 Noise Exposure Map?

Part 150 is a section of Title 14 of the Code of Federal Regulations (CFR) that sets forth the regulations and guidelines for airport sponsors to undertake airport noise compatibility planning. The Part 150 regulations were promulgated by the Federal Aviation Administration (FAA) pursuant to the Aviation Safety and Noise Abatement Act (ASNA) of 1979, Public Law 96-193. Under this Act, airport operators can voluntarily submit noise exposure maps (NEMs) and noise compatibility programs (NCPs) to the FAA for review and acceptance.

A Noise Exposure Map (NEM) graphically depicts aircraft noise exposure on and in the vicinity of an airport by presenting contour lines of equal day-night average sound level (DNL) values. NEMs provide local communities an opportunity to visualize aircraft noise exposure to make better informed decisions regarding proposed noise-sensitive development in the vicinity of an airport.
