Evanston nibbles at rules for new industry
They call it aquaponics -- raising fish and vegetables in a symbiotic environment combining aquaculture and hydroponics. And Evanston officials are trying to decide what to do about it.
After city staff received some inquiries from people considering opening industrial-scale aquaponics operations in town or pursuing the activity as a hobby, an Evanston city panel this week took a first look at possible rules to regulate it.
Acquaponics has all the attributes that would appear to appeal to Evanstonians who've backed community gardens and even backyard chickens -- and it could become a new industry to fill some vacant warehouse space -- economic development that could provide more jobs.
But this is also the Evanston that can turn out a crowd to oppose almost any new idea -- like backyard chickens, for instance.
So, like a Tilapia that might nibble on the dangling roots of a lettuce plant growing atop its pond, the Zoning Committee of the Plan Commission looked at a memo on the issue from Zoning Planner Melissa Klotz Monday night and decided to take up the question of regulation again at a meeting at 7 p.m. on Wednesday, May 16.
The memo suggests that hobby-size aquaponic ponds in residential areas are unlikely to be a cause for much concern -- but suggests there might be a need to define how big an operation can get before it's no longer considered a hobby or accessory use.
And, for commercial operations, it suggests a need to differentiate aquaponics from agricultural uses not generally permitted in the city, and to determine the commercial and industrial zones in which aquaponics should be allowed.
There already is a sizable aquaponics operation in Milwaukee that has a branch on Chicago's south side.
Plan Commissioner Dave Galloway said, "If we can have chickens in back yards, why not aquaponic ponds? I think it's cool."
But the city's chief planner, Dennis Marino, suggested commercial operations might not be appropriate for business districts, and should be limited to industrial zones instead.
