Runway 4-22 Safety Area Environmental Assessment

May 10, 2011

Auburn-Lewiston Municipal Airport

Runway 4-22Lewiston Jct RdHotel RdRunway 4-22Auburn-Lewiston Municipal AirportPurpose1. Improve safety by providing, to the extent practicable, runway safety areas that meet FAA standards for the design aircraft. 2. Provide sufficient landing length on the primary runway (04-22) to support the current design aircraft.3. Improve the all-weather availability and reliability of the airport.4. Improve safety by meeting, to the extent practicable, FAA obstruction clearance standards.Auburn-Lewiston Municipal AirportNeed1. LEW currently has non-standard runway safety areas.2. The Runway 4-22 Safety Area and Extension Study January 2010 justifies and recommends a 6,000-foot runway length. Runway 4-22 is currently 5,001-feet.
