That's an estimated 2.8% annually for a high-risk investment. It doesn't really make financial sense.

I'm not sure how you're coming up with "2.8% annually". This is an ongoing effort, not a one-time investment; the local government is spending money every year, and each year they estimate they're saving $1.32 for every dollar they spend.
