The 285 South Sustainability Alliance (285ALL) is an alliance of environmentally concerned citizens formed in response to concerns about drought, water security, and inappropriate or irresponsible development along the 285 South corridor. 285ALL includes residents from more than 20 smaller communities stretching along the Highway 285 corridor, south of Santa Fe between I-25 and Eldorado down to and including Lamy and the village of Galisteo.

The 285 South Sustainability Alliance works with local communities and policymakers to support sustainable water and growth management to minimize environmental and human impact. Through advocacy, community action and education, the alliance promotes cooperative stewardship of natural resources.
