The zoo has announced a new exhibit area called "Forest Trek". I can't find anything about it online/in the news, but they had new signs up (they weren't there in March) near the main entrance announcing it.
Based on the signs, it appears they have already secured the funding for this and will begin work soon as some of the signs say "Pardon our appearance as we prepare the area" etc.
The bald eagles, North American porcupines, and great horned owls at the zoo will all receive new exhibits in this area, while red pandas will be coming to the zoo as well.
I'm not entirely sure where this is being put, but it appears to be on the main path and looks to be replacing the exhibits in the area, such as the Rhea/Capybara and Emu exhibits.
Here are photos of the signs:
