Based on the allnovascotia.com story, the Horizon III was to proceed about 2 years ago but a wetland of 18 acres was found. It seems like they are building higher in order to save the wetland. The story describes it as a 26 story tower.
However, this story was reported first on skyscraperpage.com by someone123
