More than half of my property tax bill goes to education - why add a bond?

In all, 53.6% of your Mesa County property tax bill goes to District 51 (and zero percent of your sales and use tax). However, it’s not the percentage that factors into the school funding formula, it’s the amount. Colorado school districts rely on funding primarily from a combination of local property taxes and state funds. The state funding formula determines how much money a school district receives each year (per student), and state funds make up for whatever amount local property taxes don’t cover (for most districts, state funding covers more than half of this amount). If property values increase, the state simply back fills less. The only way to really get ahead is with a bond measure or mill levy override, which deliver dollars independently of the state funding formula.
