(Salem, OR) -- Oregon legislators are working to add guardrails on a bill that would make the state part owner of the Moda Center. The state would sell bonds to fund renovations. They would be repaid by taxes on economic activity at the arena. There are concerns the Trail Blazers could leave after the renovations are complete. For the deal to move forward, the Blazers would have to commit to staying at the arena for 20 years. Ten years into the deal, they can talk with the state if they want to leave.
