Permaculture by a Different Name: On Diana Balmori’s Arc Wildlife Crossing

Diana Balmori of Balmori Associates presented in a humble manner on major projects that speak to the core principles of permaculture, but she never called her work by that name. Permaculture is a design-focused discipline that seeks to leverage the deeply resilience systems of nature to meet human needs. Patterns observed in nature are applied to agricultural and cultural contexts. An example of agricultural permaculture are swales, which capture water running down a slope in a “ditch” and slowly release the water to plants lower down the slope. A local example is Finca Tres Robles on Navigation, which uses a city waste product, tree mulch, to grow hundreds of pounds of produce per week. An example of social permaculture is Ecoescuela El Manzano, which is a 1,200 acre community embracing village culture in Chile.

Balmori’s design for the U.S. Department of Transportation introduces a large land bridge over a freeway to connect wildlife areas. After discovering that blue pine were devastated in the Rockies by pine beetles, she found a way to turn that tragedy into a productive way to pay it forward to nature. Her firm met with a structural engineer who helped them determine that the blue pine could support the massive weight of soil and trees over the freeway. A shining example of permaculture principles.
