Monthly Development Update - May 2021
Vertical building construction is commencing at the 311 Mapleton site.
In an effort to provide our neighbors surrounding the project with a clear picture of construction activities and any subsequent impacts, monthly construction updates will be issued approximately one week before the 1st of each month during this phase. These updates will include details on current trades/activities occurring on-site, milestones, and a comprehensive trucking impact schedule.
