Experts consider such spaces to be essential to creating sustainable communities. Run-down, litter-strewn spaces, however, signal lawlessness and lack of community spirit that can lead to crime and other negative behaviors. Engaged communities are far less likely to let their neighborhoods fall into poor conditions and can act as a powerful force in preventing crime.. Minaashi Kalyanaraman . Pragya . Upreti.

The City of Rutland is losing population not just because of a regional economic decline, but also because it is not competing well against other towns when households decide where to live. Rutland has an under-valued housing market.
