Landscape Architecture Magazine- Honor Award

Sonoma Landscape Architects, Roche + Roche were honored by the American Society of Landscape Architects for their work in residential design here at Sweetwater Spectrum!   

Welcome to Sweetwater Spectrum

In 2009, a group of families, professionals and civic leaders came together and founded Sweetwater Spectrum. We collaborate toward meeting an extraordinary need: appropriate, high-quality housing choices in the community for adults with autism.   

Our pilot community has been developed in Sonoma, California. It is intended to embody best practices for housing adults with autism, with the expectation that the model can be replicated elsewhere.

We have built for adults with autism an environment typically not available to them—a place where they have a sense of community and belonging. Sweetwater Spectrum attempts to maximize residents’ individual development and independence so they can live with both purpose and dignity with access to a variety of opportunities.

This residential community is a completely new model. We have researched sites and programs across the country and selected the best elements of existing residential options in a design of a community which is compassionate and pragmatic in the choices it offers adults with autism. What we have created on a small scale is the first critical step in realizing a concept that can be reproduced in communities around California and the U.S.
