The tornado that killed eight Enterprise High School students in 2007 has prompted some systems to put built-in shelters or reinforced walls in new buildings being constructed.
While schools have been built with such safety precautions before, education and construction officials say the Enterprise disaster has pushed those design elements to the forefront when making decisions.
Enterprise High was destroyed along with nearby Hillcrest Elementary School.
Both are being rebuilt with storm-resistant features under a $1.07 billion bond issue for school systems and colleges statewide.
Jefferson County is currently building 11 new schools and they all have tornado-resistant areas. All five Montgomery County schools that are being built in the system's first phase of construction have the hurricane shelters and safe zones.
