LA CENTER — Finding room for all roughly 1,700 students in the La Center School District has turned into a slider puzzle of sorts for Superintendent Dave Holmes and other district officials.The district started putting in portables to deal with the growing population, and with nine portables — each equipped with two classrooms — at the K-8 campus, the district has nearly run out of room to put in another one. The district started shifting around offices, clearing out closet space, to help make extra room. Holmes has also suggested moving kindergarten to portables at the La Center High School campus starting next year, although the school board has yet to vote on that.But the most significant relief for the district will be decided by voters in February, when the district puts a bond up for vote to build a new school.“Over the last 10 years, our enrollment has gone straight up,” Holmes said. “We added portables, but those were supposed to be temporary classrooms. Instead, we keep adding them on and on and on. We’re maxed out on portables.”The school board is still working through the bond process, and will vote on the exact bond measure to put on the ballot in October.
