Families counting on sending their teens to the brand-new North Del Valle High School in 2027 will have to wait a year. Del Valle ISD said May 27 that the district's long-planned campus in Whisper Valley will now open in fall 2028 instead of fall 2027, citing unfinished roadway and utility work that would make it unsafe for buses, families, and emergency services to reach the site. Students who were slated to start 9th grade at the new campus in 2027 will instead begin at Del Valle High School and move to North Del Valle as 10th graders.
Why the District Punted the Opening
According to Del Valle ISD, the developer of Whisper Valley, Club Deal 120 Whisper Valley Limited Partnership, was contractually responsible for building the surrounding roadways but "has not yet secured the necessary funding" and is now in default under the Post-Closing Construction Agreement. The district says the estimated cost to finish the roadway work exceeds $12.3 million and that it has already put roughly $7 million into utility work that was also the developer's responsibility. Because those roads are required for safe bus and emergency access, district officials say the campus cannot open until they are complete.
Board Tries to Keep the Project Alive
Board materials show trustees weighed a plan to keep critical work moving despite the developer troubles. According to a Del Valle ISD board packet, trustees considered approving a Guaranteed Maximum Price proposal (GMP-03) of $6,960,000 from American Constructors to complete Whisper Valley Phase 8A critical infrastructure. The board also authorized the superintendent to accept assignment of construction and design contracts so the district could press ahead and later seek recovery of its costs from the developer. The packet includes a GMP breakdown and notes that Phase 8A work includes water and stormwater improvements needed to finish out the school site. Trustees later authorized staff to execute documents tied to those contracts while the district weighs its legal and financial options.
Where Construction Stands Now
The district says the school building itself is moving toward completion, but cannot open without road access. As reported by KEYE/CBSAustin, the campus is being designed by Pfluger Architects, with American Constructors leading construction, and has been described as roughly 473,338 square feet. Construction began in September 2025. The planned facility includes a main academic building, a field house, and athletic amenities that the district says will support expanded Career and Technical Education programs.
What This Means for Families
Del Valle ISD says students who would have started 9th grade at North Del Valle in fall 2027 will instead begin at Del Valle High School and then transition to the new campus when it opens in fall 2028. Elementary and middle school rezoning that is being finalized will still take effect in fall 2027, while high school attendance boundaries will not kick in until North Del Valle opens, according to the district's FAQ. "School districts are not designed or funded to construct or operate public roadways," the district wrote, adding that using taxpayer dollars for road construction would divert resources from student needs.
The Legal and Financial Tightrope
The district's construction update shows the project was 67% complete through April, with cumulative billing of $158,400,040 against an original GMP of $236,960,000, and that Phase 8A work, including mass clearing, waterline installation, erosion controls, and box culverts, has begun, per the May 5 board packet. Those figures help explain why the district is considering taking on critical infrastructure through a GMP, then seeking repayment from the developer, instead of letting the campus sit idle indefinitely. The financial decisions now in front of trustees will help determine whether taxpayers ultimately shoulder any of the roughly $12.3 million bill the district has estimated for the remaining roadway work.
Whisper Valley markets itself as a multi-phase, 2,063-acre master-planned community, and the new school sits inside the development near Taylor Lane, according to Whisper Valley. Del Valle ISD says it will keep posting updates as the district pursues construction, legal remedies, and rezoning plans that now stretch another year. For families, the message from administrators is blunt but simple: the building may be ready before the roads, but students will not be asked to use the campus until bus routes and emergency access are in place.
