Azle school leaders have cautiously proposed a $20 million bond program.With the last bruises healed from the 2008 defeat of a $99 million proposal, leaders visited district schools across three counties to judge public sentiment for a new plan.The leaner proposal to be presented to voters Nov. 5 focuses on two needed additions to Azle High School:• A career and technology center equipped for auto repair training, industrial arts, agricultural science and health professions,• And a new gym big enough to hold school assemblies.The third element of the bond proposal is not to be overlooked: a completely new fire sprinkler system to protect the expanded high school.Azle is a sprawling, rural school district serving children in Tarrant, Parker and Wise counties.It has not seen the enrollment growth of some adjacent districts, but that is expected to change as development nears from the east and south.District leaders have asked voters to consider only three bond issues in 25 years. A $32 million package was approved in 1986 by a 2-to-1 margin.But in 2008, voters balked at a hefty tax hike.This time, Azle’s current proposal would cost the owner of an average AISD home only an extra $25 per year.(Taxes do not go up for those age 65 and over.)Azle officials proudly say their district has the lowest tax rate of any nearby district. Even if the bond passes, Azle’s taxes will remain the lowest.The Star-Telegram Editorial Board recommends a vote for the proposition.
