Art Car parade parking?

We’re thinking about going to the Art Car parade for the first time—actually, just the pre parade lineup and maybe the kids area. One of us has a bum knee and we want to limit walking more than a few blocks…but also hopefully park in a lot where we can make a relatively easy getaway before the parade starts. Is this area a good place for that? Any suggestions? Would prefer a lot vs on the street because I am terrible at parallel parking.
