The Greater Johnstown High School expansion project, which began in the summer of 1999, represents a unique public to public partnership between the Greater Johnstown School District and the Johnstown Redevelopment Authority. The Redevelopment Authority assisted in the acquisition of seven industrial and commercial properties adjacent to the existing high school to provide for an upgraded and expanded high school campus. The Authority obtained state and federal grants on behalf of the School District to undertake assessment and cleanup activities, assuring a safe and clean environment for all visitors and users of the site. KU Resources, Inc. was retained to perform the environmental assessment and to oversee all cleanup activities, including the removal of 26 underground storage tanks. Remediation was conducted pursuant to the Pennsylvania Act 2 Land Recycling Program.

Grant funds were secured by the Redevelopment Authority from the PA DCED and the US EPA to enable the School District to continue the project without a tax increase.

The new High School and Stadium were opened in 2003. This project resulted in the creation of the first new high school building in over 75 years.  Trojan Stadium marks the first high school campus football facility in the history of Johnstown High.  The expanded high school campus boasts a new 221,000 square foot building that houses 85 academic and vocational classrooms, renovated Cochran Auditorium, and the state-of-the-art 4,200 seat multi-purpose athletic facility – Trojan Stadium.
