Camp Arroyo was designed to teach school children about the environment. The camp buildings — a dining hall/multi-purpose building, pool and bathhouse, and six duplex cabins — are part of the camp curriculum: each illustrates different sustainable construction technologies. The dining hall is straw bale construction, the bathhouses are made from stabilized earth, and the cabins are efficiently framed in FSC-certified wood.

Many other green strategies are employed including: passive and energy efficient design; solar collectors for water and space heating; durable, resource efficient and recycled content building materials, and water conservation. Storm water is dissipated on site.
