I think the supporting material (i.e., drawings) have only recently been made available on DMAP in the past 1-2 years, and even then, I don’t think every application included supporting materials in the early stages of the rollout. It seems like supporting material is being more consistently uploaded to DMAP now. I also think that applications that are >2-3 years old are being removed from DMAP if they are no longer active (I don’t see many applications that are older than 2021). You could probably contact the City’s file manager for the specific project you’re looking for more information on.
