Camp Arroyo was designed to teach school children about the environment. The camp buildings -- a dining hall/multi-purpose building, pool and bathhouse, and 6 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 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, including on-site storm water treatment.
