Changes to flood insurance mean higher costs

Changes to the federal flood insurance program are raising fears in communities from Salem to Scituate to Brockton that the costs of protecting homes and businesses from water damage are about to skyrocket as the government redraws flood zone maps and phases out subsidies.
