Massachusetts town grapples with sea rise after sand barrier fails

A $500,000 sand dune collapsed in days after being erected, and residents are looking for help to protect their homes

On the border with New Hampshire and Massachusetts - about 35 miles north of Boston - is Salisbury, a coastal town and popular summer destination for tourists. But for those who live in the town year round, especially those who live on the coastline, life's not a beach.

Last month, after a series of storms battered the area, local citizens came together to take the necessary steps to protect their homes. Volunteer organization Salisbury Beach Citizens for Change raised more than $500,000 to erect a 15,000-ton sand dune - a formidable barrier that would hopefully protect at least 15 beach houses from destruction.
