Narrative:

Called for takeoff to follow company helicopter on a basin departure. Tower reported traffic in final for touch and go for 16L and cleared us for takeoff via the parallel taxiway. (Departure point was approximately 1700 ft south of threshold). We acknowledged and observed an aircraft on about a 1/4 mi final and departed. Just after departure, an airplane rolled out of FBO and turned north on taxiway. We were about to drift right to avoid other flight when we observed an airplane at the same altitude (off to the right). We deviated left to avoid any further conflict. Horizontal distance was approximately 100 ft. In telephone conversation with tower, we confirmed aircraft was the touch and go aircraft, apparently followed through quickly. Tower pointed us out to him on another frequency. Aircraft had us in sight.
