A fire that burned some of the roof and attic above the library at Harvest Park Middle School has forced the Pleasanton Unified School District to convert four portable buildings into book storage facilities.

The fire at the school on Valley Avenue occurred at about 10:30 p.m. July 3. The Livermore-Pleasanton Fire Department (LFPD) had it under control about a half-hour after arrival.

LPFD was joined in the first-alarm call by the Alameda County Fire Department. No one was found on campus. The cause is under investigation.

School Superintendent David Haglund and other school officials joined City Manager Nelson Fialho on the scene to work with the Fire Departments.

Most of the damage was in the roof. Many of the books and computers were salvageable, said a district spokesperson.

The school district has secured the area around the library, and is asking people to refrain from visiting the school as a safety precaution.

The school board, at a special meeting July 6, voted 4-0, with one absence, to bypass the usual bid process for reconstruction, so that work can be begin more quickly to restore the building. The resolution needs to be approved by the Alameda County Office of Education.
