The AZCentral.com website has an article describing Mesa's choice for bond issues coming up in November.

City Council will choose between two bonds: one costing less and funded for two years and one for more money over a 5 year period. You can read the details on the City of Mesa website:

There is a presentation with a comparison at:

I haven't read them yet, but I plan to do so very soon. I hope you will also and offer your thoughts here.
