Yeah, I'm going to be that guy and say that's not nearly enough parking. Most of the time I'm against big parking lots like all good urbanists, but parking at GP sucks already and it's been an issue for the entire area. Add a huge new kids museum on top of that and I simply don't know how it's going to work with even less spaces. They simply need a big donkey parking garage, and they needed it before the place opened.
Encourage Uber and more transit use.
If we can build places that are very desirable to go to, Downtown (Guthrie Green/Arts District), Peoria BRT corridor (which connects to Cherry Street & the Pearl), 11th street BRT corridor, The Gathering Place, Transit from downtown toTthe Gathering Place.... and they all have the "parking problem" perhaps we can finally get people to begin using more Uber and Transit.
Really once you do either of those a few times, you can begin creating a new habit. It's just getting peoples thoughts to "remember" the other options. We use Uber all the time.
If the Mid-Town/Downtown and adjacent crowd (which is a significant number) can use those options more, it will free up parking for those who live further away.
You don't want parking too convenient. You want to have a little pressure to get people to get that habit of using the other options. Once they do start using those options more, it begins to "bend the curve" grow the transit, grow the desirability and density, etc.
If we can't do it when the rewards are there to entice people, we certainly won't do it otherwise. Seize the opportunity.
You and I can be a part of helping that transition. Tell your friends, "Hey lets Uber here and do dinner." etc.
