A group of local residents is looking into the viability of establishing a cohousing community in the Gorge.  Cohousing advocates say such communities help people find and maintain elements of traditional views of neighborhoods, including family, community, and a sense of belonging.  Cohousing designer Katie McCamant is working with the Gorge Cohousing group, and says the concept can address affordability issues by providing common facilities ranging from a common house to shared green space.  Gorge Cohousing has set up a website, gorgecohousing.com, to outline the concept, with a presentation planned October 21 at 7 p.m. at Springhouse Cellars in Hood River.
