I would encourage you to check out the Tribune article from last week about plans for the Zoo.
The North Pacific Aquarium is almost 50 years old, and it's time we start planning ahead, either to build a new aquarium, or to close the one we have. The concrete building has held salt water for that whole time, and salt water and concrete just don't mix over the long term.
Discussions about the aquarium are part of the bigger picture planning we've been doing for the last couple of years: what species do we want to focus on, what facilities does that mean we need, and what would it take to build them.
There's some very interesting opportunities in the mix, so again, check out the article!
