Compliance with FAA airport geometric and separation standards, without modification to standards, is intended to meet a minimum level of airport operational safety and efficiency. Table 3-11 compares the FAA airport design standards for both runways, based on the recommended and existing design. Unmet design standards are denoted by a bold “X.” Elements determined to be deficient include the Runway 16L-34R runway shoulders (discussed previously in Section 3.5.3.4, Runway Widths) and the holding position markings on both runways. The holding position markings must be 254 feet from the runway centerline. AC 150/5300-13A specifies the holding position marking separation from the runway centerline should be 250 feet at airfields at sea level, and increased one foot for every 100 feet in elevation. EUG field elevation is 374 feet above sea level, therefore the holding marking separation must be increased by four feet. It was found that the holding position markings at Taxiway A4 and A5 were separated two to three feet less than required from the Runway 16R-34L centerline. All the holding position markings for Runway 16L-34R were found to be 250 feet from the runway centerline, which is four feet short of the requirement. EUGENE AIRPORT MASTER PLAN 3-15
