Many years ago, they had a masterplan for the zoo that involved having many domed buildings just like the TF, with underground passages connecting them. This way the zoo would be great in the winter weather when many animals cant go outside. The guests could experience the entire zoo indoors. Each of these buildings were to be themed like a particular african biome. There would be a rainforest dome, savannah dome, desert dome, etc. Some were two or three times as large as the TF. They also all had exhibits that gave the animals the option to be outdoors in warm weather, and so during the summer, guests would be able to watch the animals outdoors, or indoors. This was all after most of the buildings in the zoo had been knocked down, or abandoned (this includes the old bear cages and old elephant house). The zoo at some point was also cut in half- If you look on google maps, the baseball field to the west of the zoo was once part of the zoo grounds. Ultimately, when construction on this new masterplan began, they realized this was going to be far too expensive, and so they decided to build only one new building, which was the TF. At some point in this process, the elephants were replaced with gorillas, which is probably for 1 of 2 reasons. First, gorillas are much cheaper than elephants, and this fits with the theme of them being low on $. Second, there were already gorillas at stone zoo, in a bad exhibit, and so those gorillas could just be moved to franklin park.
Today, it seems unlikely that Franklin Park Zoo will get elephants ever in the future. The zoo staff claim that they do not have enough space in the park, even though the zoo is more than 70 acres, and most of the land is unused. I think the real reason why they cant is because of the money. The most likely new big animal to be added to the zoo is probably southern white rhinos. The giraffe savannah exhibit was originally meant to include giraffes, zebras, and rhinos, but rhinos were cut last minute. The exhibit has a strong enough fence for the rhinos, and is large enough for them, they just need to build the barn. It would be a great addition, since rhinos can withstand colder weather than giraffes, and so that part of the zoo would be much less empty for more of the year.
The zoo is not doing too well financially, and really struggles with having a lot of empty space, and not as many animals, in my opinion. If you look at the original plans for their new children's zoo, nature's neighborhoods, and the final result of the construction, you can see what I mean. The next big construction project is a new entrance, and after that is some big waterhole exhibit, so we will see how those turn out. On the upside, they are growing (slowly), and are raising money faster than ever before. The zoos struggle materials-wise, and financially, but overall have a wonderful and very very dedicated staff and volunteers.
