Five Rivers Aviation, the sole business aviation ground handling provider at San Francisco-area Livermore Municipal Airport (LVK), has broken ground on its second phase of construction that consists of a 43,000-sq-ft hangar. The $9 million project at the six-year-old FBO is expected to be completed early in the fourth quarter. This expansion will accommodate the latest ultra-long-range business jets and bring the Avfuel-branded facility's overall aircraft storage space to 68,000 sq ft. Planned third and fourth phases of development will more than double that total.
