Greater use of automation and mechanization within cargo buildings will have a dampening effect on employee growth at airports. Typically, a minimum of two to eight employee parking spaces should be provided for every 1,000 square feet of warehouse and two to eight spaces for 1,000 square feet of office even if local building codes allow less. Where development area is limited, alternative locations for employee parking will have to be considered. This includes remote lots that utilize shuttle services and rooftop parking.
