Air Traffic Control Issued New Clearance
Airspace Structure; Human Factors; Procedure
Aircraft X was an IFR overflight requesting a practice approach. I had a handful of other aircraft at the time but traffic volume was not a factor. While I had Aircraft X on a downwind heading I was also checking a full route clearance for another aircraft to ensure it was good. This resulted in a late turn to base. I realized I had an MVA (Minimum Vectoring Altitude) issue; so I climbed Aircraft X to 8;000 ft. After doing to the low altitude alarm went off; but because I had already issued a climb I did not issue a low altitude alert. Because there is terrain along the final approach course that requires precise altitude control and base turns; I should avoid getting caught up in other duties until I have turned aircraft base; especially for fast moving aircraft.
TRACON Controller reported they were late vectoring an aircraft from downwind to base leg and the aircraft flew below the Minimum Vectoring Altitude.
