Oshkosh board weighs $1.6–$1.7M replacement of North High gym floor over mercury off‑gassing risk

The Oshkosh Area School District briefed the board that the fieldhouse floor at Oshkosh North High School has “reached the end of its life” and that the original poured‑in‑place urethane — which was later encapsulated under a wood floor — is degrading and can off‑gas mercury vapor.

Mister Fox, who presented the facilities assessment, told the board the district has taken air samples and that current readings are within permissible exposure limits. He said the district faces two paths: continue monitoring and defer replacement, or move ahead with demolition, abatement and installation of a new floor on an accelerated schedule to avoid an uncontrolled health or scheduling emergency. “We need to choose a path that OASD wants to follow and we need your guidance,” he said.

Administration and the facilities and finance committee laid out the practical and financial tradeoffs. Option 1 — continued sampling and monitoring — avoids immediate capital expense but risks an unpredictable spike in emissions later that would require an emergency shutdown and more disruptive, likely costlier, remedial work. Option 2 would schedule abatement and replacement in late spring and summer with a controlled negative‑pressure abatement process; the district’s early planning estimates demolition, abatement and replacement at approximately $1.6–$1.7 million.

Dr. Herzog and committee members recommended the district proceed with the replacement planning to retain control over timing and safety. Committee members noted possible funding sources could include any current‑year surplus and Fund 46 (capital improvement), which the board was told currently holds less than $4 million. The committee agreed to draft a resolution for board consideration that would identify funding options and authorize next steps.

Board members pressed administration for details about schedule risk, worst‑case off‑gassing timelines and how removal would affect summer programming. Administration said similar floor removals in other jurisdictions have taken up to three months for off‑gassing after urethane removal but emphasized that the planned strategy — using negative pressure, HEPA filtration and phased scheduling — is a standard approach designed to keep other school areas safe while the gym is unavailable.

Next steps: administration will return with a resolution that outlines funding options and a proposed timeline; the board indicated the item will be brought forward for formal action at a subsequent meeting.
