Human Factors
We were approximately 5 miles east of DBL at 14;000 when approach control assigned us a heading and cleared us for the visual approach to RWY 15. The Captain asked me to sequence the FMS to the 9.9 nm runway extension as he began descending to 12;300 ft to intercept the final approach course. As we passed north of DBL; we received a terrain caution at approximately 13;800 ft. The Captain disconnected the autopilot; leveled momentarily; and we resumed the approach. The caution cleared immediately after the descent rate was reduced. We both had the terrain in sight and maintained visual separation before and during the event.The cause of the event was a misjudgment of our proximity to DBL. We both felt we were north and well above any hazardous terrain. Contributing factors were a hurried approach environment complicated by the need to configure; descend; and manage the FMS in a short time period. Another factor was an abnormally short vector that placed us further south than usual. In the future; I will be cognizant of a vector that places us in close proximity to DBL and suggest that we do not descend below 14;000 ft until passing its general vicinity.
