Unofficial voting results show Pflugerville ISD voters passed the biggest bond package in the school district's history.

About 64 percent voted in favor of the $287 million PISD bond measure, the district's first bond election since 2007.

The bond would allow PISD to keep pace with its 400-student-per-year growth trend, according to pfisdbond.net.

The bond will pay for new facilities and improvements to all PISD's existing facilities. Taxes will not be increased to pay for the bond, PISD officials said.

"We have a community that is extremely supportive of our school district and today's results are a clear reflection of that. We want to thank the entire Pflugerville ISD community for its continued support of the school district," PISD Superintendent Alex Torrez said in a statement.

"Today's vote is a win for our children, our schools and our community. It's a balanced and comprehensive bond that touches every campus in the district. We're very happy for all the support we've received from the public during this process and the leadership of our board of trustees who brought the referendum to the voters," Torrez added.

Jessica Rotz, treasurer for Vote Yes PISD School Bond Political Action Committee, said each aspect of the bond package addresses a district need.

Those needs include "overcrowding that we face in our schools and security needs and repairs and upgrades," Rotz said. "Everything boils down to the growth factor."

District officials formed a Citizens Facility Advisory Committee, a group of community members and PISD employees, to examine the costs and frame a possible bond proposal for the district's board of trustees to consider.

Bond money allocation:

$188,350,000 will pay for a fourth high school, a new elementary school, a replacement elementary school for Timmerman Elementary, a district stadium and a land acquisition.

$67,887,000 will fund renovations, additions and improvements to existing facilities.

$24,763,000 will be used on district-wide updates for technology, safety and security.

$6,000,000 will go to the bond program contingency and bond issuance cost.
