This "concept plan" is up on the Plaza Retail REIT website, concerning their "Moncton East Lands".
The document is dated September 6th 2018, and shows the parcel of land south of Babineau Blvd, along the NW corner of the Harrisville Blvd/Highway 11-15 interchange.
The document appears to show a plan for four six storey apartment buildings on this site.
I have no idea if this plan is there just for discussion or demonstration purposes, but is an interesting proposal nonetheless. This parcel was one of the rumoured finalists in the competition to host the replacement Costco in town. Another rumour floated several months ago was that this might be the location for a new Sobeys store servicing the east end of the city.
