Here is the master plan:
JOHN BALL ZOO MASTER PLAN
Also, The local homeowner's association is saying that they are "vigorously opposed" to the master plan, due to it turning a current field area into parking.

I printed off the Master Plan and spent some time reviewing it. The future seems much more realistic for John Ball Zoo in comparison to various other zoos that have Master Plans full of proboscis monkeys and unicorns.

I was pleasantly surprised during my visit in 2012 and I'd like to see this zoo do well in the future. With an average attendance of around 500,000 in only 8 months of operation, it seems to me that the facility has carved out a niche for itself in Grand Rapids, Michigan.
Some thoughts in point form:
- the new tiger complex appears to be much more impressive than the relatively new grizzly bear exhibit. Having two tiger exhibits and a 200-foot trail connecting the habitats reminds me of the trail system being built all around Philadelphia Zoo.
- the parking issues at the zoo are well known, with many folks simply parking on the nearby grassy fields. It seems that a lack of parking is a common theme for many growing zoos.
- the entrance to the zoo is arguably its weakest feature and it is wonderful to see that being addressed in the Master Plan. A pair of American black bear exhibits, connected via an overhead trail, is a brilliant idea and that notion of having black bears near the entrance is something that Oregon Zoo and Knoxville Zoo are also known for. The current uphill trek past minor exhibits at John Ball is a poor initial impression.
- together with the brand-new tiger exhibit, the future American black bear exhibit and now the future Primate Overlook Trail, John Ball is certainly adopting the trail system that is found at Philadelphia Zoo.
- the Africa Expansion section is very vague and there is a photo of an Indian rhino. That is an elementary error to be included in an official Master Plan document.
- I really like the idea of the hubs/plazas, which are visitor zones that can incorporate cafes/restaurants/gift shops into open spaces. Those areas can also separate sections of the zoo from one another with clarity and purpose.
