With classes out for summer, for the Hood River County School District it’s now time for maintenance projects on district buildings to take place.  Superintendent Dan Goldman says the biggest project is at Hood River Middle School, where the temporary boiler used in the past year has been replaced by another temporary boiler that could become permanent depending on how renovations of pipes in the building progress.  Goldman noted bringing in the new temporary boiler is less expensive than what they have been doing since the original boiler went out before the just concluded school year.
