It's sounds like a Utopian hallucination. It's all free says Mayor Hancock... except if property values go down in the next 3-5 years or more and the city needs to raise property taxes  to cover the interest payments on the bonds.

Only Tier 1 facilities receive money from (2B), not smaller tier 2 and 3 local non-profits   The large facilities already receive 70% of the SCFD funds now! 
Why not user fees? 
Money that was approved on a Bond issue for remodeling Boettcher Concert Hall few years back  was never matched so the City has put that money in the General Fund.All funds allocated by these Bond Issues may never go to what they are selling here. 

The libraries do need funds,however even late fees for tardy returns go into the City's General Fund-they don't even go to the library.

Any developers paying for some of these projects which will profit them more than the average Denver Resident? Some excellent projects however the unsound way to fund them.
I will vote NO on all.
