Library districts are the most common form of library system in the state of Colorado. They are funded by a property tax on the assessed value (not actual value) of a home. The proposed tax is $26 per $100,000 of assessed value. For the median value Boulder home, the increase is in the range of $240/year.
Right now, only city taxes pay for the library, even though 30% of cardholders live in outlying areas. The people of Gunbarrel and other unincorporated parts of Boulder county would be brought into the tax base, so that it more closely matches the user base of the library. A library district is the most equitable way for a community to support services -- and avoids the regressive nature of sales taxes on which much of Boulder's city budget relies. The exact amount of the tax will be defined as part of the district formation process, and all voters in the district will have the opportunity to vote on whether to impose the tax.
