This is an ambitious idea because using aquaponics growing techniques is the way of sustainable organic food production of the future. If done right aquaponics vertical farming grows up to 22x more food per year in the same square feet as terestial growing, using 5% of the water, and staying organic. Reduces our carbon footprint drastically by eliminating transportation of food. With modern lighting technology the cost to produce is reduced significantly. It would make a great gathering place for community. This is the future, we can be the first to do it as a city. To my knowledge anyway

Personal health surveys.

With growing awareness aquaponics growing systems are being developed and improved around the world rapidly. The systems already exist we only need to implement them.
