The Outdoor Learning Environment program at Casa Grande High School in Petaluma is coming together, according to backers on campus.

The footprint for two outdoor classrooms, an amphitheater, garden, orchard and kitchen are set. Irrigation is in and crushed rock pathways are in place.

The next big fundraiser for the project comes on Wednesday when Whole Foods in Petaluma will donate 5 percent of all sales to the project.

“The teachers here at Casa are really excited about incorporating this new environment into curriculum for science, math, history, English, public speaking, drama and music,” Casa teacher Megan Donner wrote in an email. Donner is a culinary instructor at Casa who is the OLE coordinator.

Donner said the school is hoping that proceeds from Wednesday’s fundraiser will help the school put in an extensive irrigation system and buy fruit trees for the orchard. That portion of the project is expected to cost $30,000.

Depending on fundraising, the school hopes to have the project complete by August 2013.
