Comal ISD estimates that a one-year delay in its proposed bond construction would add about $27 million in project costs, using an architect’s March 2026 analysis and estimated construction inflation of at least 5%.
The figure appears on the district’s Bond 2026 financial page, which says actual costs can vary with market conditions, project scope and timing.
For taxpayers, the $27 million is a district estimate of additional project cost, not an annual household tax bill. It describes what the district thinks a year of waiting could do to construction prices. It does not tell a homeowner what the bond would add to a tax bill.
What does the estimate measure?
Proposition A would authorize $539,955,000 for facilities, land and buses; Proposition B would authorize $27,045,000 for classroom technology. The proposed borrowing totals $567 million. The district’s delay estimate concerns project costs, so it should be read separately from the size of the ballot propositions and from the eventual cost of borrowing.
Construction inflation changes what a project might cost to build; financing determines what taxpayers ultimately pay to retire bonds. A faster schedule could reduce exposure to rising construction prices, while earlier borrowing would bring debt payments forward. The delay estimate does not settle that trade-off by itself.
