Take the farmers market in des moines, where they block off the streets once a week. There always seems to be parking for the massive influx of people for that. Valley Junction has parking surrounding it and plenty of streets. I just don’t see it being an issue.

As for residential, you’d be surprised how quickly apartments are built after areas like this are built, immediately the value of the land goes up. Turns out, people like having nice places to hang out in.
