Distance from LEED building to public transit stops is too far to meet requirements, however distance from the guardhouse gate controlling access to the secured site on which the LEED building is located would meet the requirements. What's the likelihood LEED reviewers will accept the guardhouse gate point as the "entry" from which the distances are measured? What if owner provides a shuttle from the guardhouse gate to the LEED building to in essence bridge the gap? The shuttle could be set up to accommodate all workers, transporting them at the beginning and end of each shift.
