Aircraft X was flying the KNIK2 SID out of ANC. The system initiated a Low Altitude notification. I issued a Low Altitude Alert to the pilot and advised an immediate left turn and climb. Recommendation: KNIK2 procedure change to include a DME arc not to penetrate during departure. This will give a finite point in space that is unable to be violated; and to preclude confusion about the SID wording by offering a hard boundary as a graphical depiction.
A11 TRACON Controller reported a low altitude notification for an aircraft flying the KNIK2 SID out of ANC airport.
