1. All the parking is parallel parking along all the streets. This ensures that the number of businesses don't need their own massive ugly parking lots
2. There are actually apartments here above the businesses, so that it's always active, the people that live here keep the businesses below in business. We have everything from lawyers to gyms to dentists right below my feet in a single square mile.
3. This is actually a community. We have multiple community events and I can just show up and be there. We have a big shopping day every first Friday of the month where local merchants will set up tents and sell their stuff. They also do some event for nearly every holiday.
4. The entire town center is walkable. A square mile of walkable businesses, a park, a pool, etc.
