andrewr,
All of the STARs to RW 34 through OBGAL-AKDEL and BOLTY-AKDEL have a minimum segment altitude of 3000ft to connect to the RNAV RWY 34 approach. The protection areas for theses STAR's sit over the VFR lane. The STAR tracking for the GLS 34 are not changing, but because the altitudes are lowering a piece of airspace had to be acquired to protect the STAR and turn onto the localiser at 2500ft.
Lateral tracks are not changing from the current STAR-RNAV tracking. It is just being lowered at AKDEL by 500ft...that's it
