Generations of Hope is a nonprofit adoption agency that has designed a community to resemble a nurturing small town, complete with surrogate grandparents. Created out of a shuttered Air Force base, Generations of Hope seeks to rescue children from foster care and place them with adoptive parents who have moved here. About 30 children currently live with parents in 10 homes. The community is also home to 42 older people who have subsidized rent.
