Southwick residents love the natural beauty and the many recreation choices their town offers but they also like reasonable tax rates. Russell Fox, chair of the Southwick Select Board, said to accomplish both means business development must be part of the equation to ease the tax burden. “It’s a balancing act that the Select Board takes very seriously,” said Fox, who has been a selectman off and on (mostly on) for more than 40 years. “I would not want to see families who have lived in town for generations say they can no longer afford to stay here.” A balancing act indeed, as last year residents made it know that they will support some business development proposals, but not all. After the town’s planning board and select board had approved a $100 million project involving the online used car seller Carvana, residents expressed a number of concerns about the size of the project and its impact on the community.
