Way too much capital investment. P&L is empty 200+ nights a year. And the mega districts like this are actually becoming out of favor nationally.
I like idea of business between stadiums, it's lacking. Cut down bldgs/capital investment 75%, add in scale up/scale down infrastructure (like power for food trucks, string lights, crushed limestone). Beer gardens with shared large wooden tables, plant some trees, could make a cool atmosphere for less cost.
For business office space, is it adding jobs in Ames? If not, it's just competing with downtown Ames and Campustown.
For consumer spend, will it cause more to spend in Ames? I think could get similar spend if all outdoor with a lower cost option (scalable up and down detailed earlier). This plan does not seem to be optimized for ROI. If want year round spend, need climate control for winter. Wild to me to see this much infrastructure, but no 4 seasons atrium for a significant portion of middle area.
