Sweetwater Spectrum is an innovative and pioneering model for meeting the unique everyday living needs of adults with Autism. Building on published research and working with the non-profit board of directors, the City of Sonoma, the architect, and other consultants, the landscape architect fashioned an environment that supports the project’s goal of providing the residents a ‘life with purpose’.

The 2.8 acre campus in the City of Sonoma includes four residences, each with four bedrooms; a Community Center with teaching kitchen, workout studio, library, and a space for art and music; a therapy swimming pool and two spas; pathways, site furnishings, play lawn, hammock garden and plantings; and a 1.25 acre organic vegetable garden and orchard.

The site, landscape and organic gardens are an integral part of the living, working, learning and social environment for residents, staff and visitors at Sweetwater.
