In 2015, a $361.4 million bond package passed board approval and a citizens' vote. The package allowed for major renovations to all six existing campuses; the addition of a parking garage at Highland Park Middle School; the addition of new surface parking at Highland Park High School; the demolition of the high school's natatorium; and renovations to the Seay Tennis Center, the Multi-Use Building, and Highlander Stadium. Stantec Inc. and Balfour Beatty Construction were eventually hired to oversee most of the design and construction that ensued. In February 2016, the District sold $225 million in bonds with a 20-year amortization at an interest rate of 2.95%—lower than had been originally expected. Tax rates naturally increased within the District to cover the additional costs.
