The Santa Ana Unified School District board will review a plan tonight to replace hundreds of portable classrooms throughout the city with multistory permanent buildings.
About 900 portable classrooms are in use at schools throughout the city, school board President John Palacio said.
The bungalow-like classrooms house students in what has become one of the most crowded school districts in the state, district officials said.
Santa Ana Unified has about twice as many students in portable classrooms as Tustin Unified has students, officials said. And the number of students at Irvine Unified roughly equals the number of students in portables in Santa Ana Unified.
But at many schools, the portables occupy space on playgrounds or parking lots.
Also, most of the portables are leased, Palacio said.
The school district plans to use the $3 million or more spent each year on leasing portable classrooms to build two- to three-story permanent buildings.
