Supporters of Outdoor School say they have a plan to save the program.

The Portland Public Schools proposed budget released last month eliminates the popular environmental program. Outdoor School boosters announced a tentative package Thursday with funding from as many as seven entities, including two non-profits and five government agencies.

Rick Till is on the board of the East Multnomah Soil and Water Conservation District. It’s committing $150,000.

“I’m very optimistic that we can close the gap for this school year. But the future is still uncertain, and this buys us time to find long-term solutions,” Till said.

But some of the funding for next year isn’t confirmed yet. The Conservation District’s money relies on a similar commitment from Portland Public Schools. School officials say they’d like to help, but say they haven’t found their share of the money. Outdoor School supporters are still negotiating with the city of Portland, Metro, and the soil and water district in West Multnomah County.

The plan also anticipates higher participation fees from Portland families.

Portland Public Schools negotiated a deal last week with its teachers’ union and the city of Portland to maintain 110 teaching positions.
