I'll take
@Mister B. idea and make some additions and subtractions...
19.5 Acres would be for public consumption:
4 - Acres - Greenhouse Garden, farms and, farmers market,
0.5 Acre - Hotel
1 Acre - sports complex
3 Acres - Three Schools from K-12 (Elementary, Middle, High), university, trades school
3.5 Acre - Housing for Middle Class Families
1 Acre- affordable housing condos
1 Acre - hospital, retirement home
1.5 - Acre - hydro plant (would have to be near a strong enough water source)
4 - Acre - Businesses, civic building
0.5 Acre - my private land
Transit line throughout.
Soon enough we gentrify the next towns over and inject more black businesses and look to build more homes for all classes. Rinse repeat sustain.
