While making a left hand turn exiting the terminal ramp onto taxiway A for a planned departure from runway 32 the left main gear wheels departed the taxiway pavement and subsequently became stuck in the mud/grass. We were conducting this taxi as a two-engine taxi as per the requirements of the departure notes on the 10-7L page in our Jepps. The event occurred at a very slow taxi speed. After coordinating with the station operations personnel; the passengers were deplaned from the aircraft via a ramp and escorted back into the terminal. A maintenance team was flown in. The aircraft was pulled out of the mud/grass and inspected by the maintenance team - no faults were found and the aircraft was returned to service. The biggest threats are the very narrow taxiways and the very limited pavement/concrete in the turn radius leaving the terminal ramp. This event could be prevented by widening the intersection leaving the terminal ramp (which we were told is scheduled to occur in the near future because this sort of event has occurred a couple other times in the same spot). Adding additional information the 10-7 pages of our Jepps to alert other pilots about this particular intersection could also help.
Regional Jet First Officer describes a taxiway excursion while attempting to turn from the ramp taxiway to Taxiway A at DIK. The aircraft becomes stuck and the flight is canceled. The site of the excursion has apparently been visited by other aircraft and is scheduled to widened.
