Seasidecouncils have formed the Coastal Communities Group to press for action on regeneration and climate change, co-ordinated by East Lindsey DC.
Members say the group is required followed a "disappointing" government reaction to a communities and local government select committee report, in which MPs called for measures to tackle the towns' economic weaknesses (LGC, 8 March).
The report concluded that the towns had "hit and miss" support from central government and some were sent excessive numbers of vulnerable children by councils elsewhere.
Problems the 34-strong group intends to raise include physical isolation, and a combination of transient populations that suffer from low wages and high unemployment, though often with high house prices caused by the arrival of retired people and urban 'downshifters'.
Climate change is a major fear on the coast, with threats from erosion and floods.
"The problems are common, but there is no national strategy for dealing with them and no government framework for guiding best practice," a group spokeswoman said.
