Gary Comer Youth Center roof garden in Chicago, IL is a non-profit in-place garden, growing 1,000 pounds of food annually and feeding 175 children at the center daily. Soil is 18-24" deep in growing areas. The garden won the ASLA Honor Award for General Design in 2010. The garden design translates traditional farm rows into a playful urban space by alternating the row sizes, and uses concrete bands between rows.
