Aeration or water inflow is critical if you want it to support a food web ...
Fountains are not.
That picture looks cheap and I really hope that we go in a different direction.
Its a freaking detention pond. I'm all for making it look nice, but this is an engineered structure to hold back storm water flows first and foremost
Actually, no.
A detention pond is a structure built that controls storm water flow, and outside of rain events is typically a dry structure. Some hold water annually, but are designed with enough freeboard to operate as designed during storm events. What is proposed at Spence is not a structure that will be designed to mitigate storm flows.
This is an ornamental water feature - it will have water in it full time, and as such will need a feature like a fountain to circulate and aerate water to prevent stagnation. Any benefit for aquatic life resulting from circulation and aeration is likely just a side benefit. Same as the water fountain found at the front of almost every single development built these days - it's for looks, and pretty much nothing else.
It still could be a retention pond. A detention pond is typically dry except when it's filled with storm water or river overflow. A retention pond maintains a body of water year round and is also used to control runoff from storm water. Detention=ugly, retention=possible year round water feature.
A retention pond with aeration is basically the opposite of what the original argument stated.
Admit defeat and move on.
Moreover ... If it isn't lined then it will absolutely support a food web.
I say again, I'm putting bass and bluegill in that mfer as soon as it's ready
