A new report has said coastal councils in this region, could be put under financial pressure by the Government's welfare reforms.
Towns such as Great Yarmouth and Clacton on Sea, with high numbers of people living on benefits, will be hit hardest.
The Local Government Association said councils may have to cut spending in other areas, in order to support tenants suffering as a result of housing benefit changes.
Two projects designed to boost seaside economies will benefit from more than £1.5m.
Suffolk County Council is to receive £762,000 to create 200 new apprenticeships.
The money will allow them to develop skills for the low-carbon energy sector in coastal communities in Norfolk, Suffolk and Essex.
The RAK Maritime Project will receive £757,000 to provide maritime training to 63 young people each year over two years to support the renewable energy industry in East Anglia.
The money comes from a Government scheme designed to boost the economies of seaside areas.
It forms part of a £24 million Coastal Communities Fund launched earlier this year and further projects will be announced over the coming months.
