Rehabilitation of Runway 8R-26L and Associated Airfield Improvements

Rehabilitation of Runway 8R-26L and Associated Airfield Improvements

A focused Supplemental EIR is being prepared to supplement the 1991 Certified Final EIR for Terminals, Other Facilities and Operations to Support 12 Million Annual Passengers (“1991 Certified FEIR”) for improvements proposed at ONT to meet current Federal Aviation Administration (FAA) standards, improve safety, and enhance airfield efficiency. Connector taxiways will be reconstructed to align more closely with current FAA standards, as well as to improve pavement conditions for air traffic throughout the airfield. The proposed pavement sections will be designed for a 20-year life for all shoulder pavements, blast pad pavement, and for the new taxiway pavement. Runway 8R-26L requires rehabilitation and reconstruction as it was built in 1979 and has exceeded the intended design service life of 20-years. Additionally, there are objects located within the Runway Safety Area (RSA) and Runway Object Free Area (ROFA) that need to be relocated to meet FAA standards. The airfield drainage includes tributary areas on the airfield located between the runways and taxiways. The proposed improvements are not increasing the airfield drainage areas, however they are being modified to accommodate existing connector taxiways and construction of the new connector taxiways. The proposed improvements will not result in increased runway capacity. During runway closure periods during construction, all operations would occur on a single runway. Due to the two runways being parallel and closely spaced, temporarily operating on a single runway would not significantly alter flight patterns. The only change in flight patterns during temporary runway closure periods may result from FAA Air Traffic Control (ATC) imposed restrictions on the use of contra-flow operations during nighttime operations, which is a noise mitigation strategy to minimize noise over residential areas at night. If contra-flow cannot be undertaken by ATC when operating on one runway, there is potential for temporary increases in noise exposure to the west of the Airport during nighttime. Runway use and flight patterns would be not be impacted after the project is implemented.
