ANCHORAGE -

One small-town Alaska mayor worries that rising costs for national flood insurance could be another push for people to abandon life in rural Alaska.
    
Jacques Longpre is the mayor of Aniak, on the south bank of the Kuskokwim River about 320 miles west of Anchorage.
    
He says most households there pay about $700 a month to heat and power their homes, and with higher flood insurance rates, it could make places like Aniak unaffordable.
    
Congress rolled back spikes in premiums instituted in 2012 to offset a $24 billion shortfall in the National Flood Insurance Program, but more than 1 million policyholders across the nation will still see higher costs phased in over time.
    
Across Alaska, 422 policies face higher premiums.
    
In Aniak, a community of about 500 people, there are 23 policies facing hefty yearly increases.
