Crosby & Blundellsands Labour Action Team has contacted Sefton Council to call for urgent action to deal with displaced sand in Brighton-le-Sands.
MP Bill Esterson and Crosby & Blundellsands Labour Action Team's Veronica Bennett have received scores of complaints from residents concerning the sand which has covered the fields and spread to the properties from Mariners Road to Glen Bank.
The sand has become a particular problem following the recent heavy winds and the dunes restoration project.
Veronica said: "The Labour Action Team and I have received a number of complaints from Brighton-le-Sands residents about the condition of the dunes and grass fields from Mariners Road to Glen Bank. Bill Esterson MP and I have visited the area and we share the residents' concerns.
"The problem has come about because of the recent work which has been done as part of the dune restoration project, which has seen sand moved from the dunes in Brighton-le-Sands to Hightown, closely followed by the high winds.
"Footpaths have been obliterated and lots of gardens are now covered in the sand."
Veronica and the Labour Action Team are concerned that the sand could also cause damage to the drains.
Veronica said: "We have asked for the area to be cleared, the roads to be swept and the drains checked as soon as possible.
"Rubbish has also been exposed from beneath many of the dunes and this also needs to be cleared as soon as possible too.
"Like the residents of Brighton-le-Sands who have contacted us, we don't want to see the dunes removed or decimated. But where they cover the promenade and reduce access to the beach, we want to see them managed in a sensible way. The area is protected by EU law and Bill will be applying to Natural England to request that the council is given permission to manage the area, where needed."
Bill Esterson said anyone with further concerns should contact Veronica and the Crosby & Blundellsands Labour Action Team.
Bill said: "Sefton Council are now aware of this problem and they have assured us that they are taking immediate action.
"But because of the ongoing work we will continue to monitor the area and speak to residents about any concerns they may have."
