Narrative:

CL61 was cleared for takeoff on runway 01. Helicopter called requesting a southeast departure (sierra route) from northwest corner of the airport. Helicopter was instructed to remain west of runway 01 and proceed sbound! Helicopter made a climbing right turn off the ramp and crossed the runway at 20 ft AGL as the CL61 rotated and overflew the helicopter by 100-200 ft. Once the helicopter realized he shouldn't have crossed, he continued eastbound at a low altitude.
