A cheque for almost £20,000 is being presented to the North Cornwall Flood Disaster Trust on Saturday.
The floods happened last August
It has been collected by the Mayor of Saltash who set up a fund after seeing the devastation caused by the flooding in Boscastle and surrounding villages.
It brings the main fund up to almost £400,000. Councillor Sue Hooper will hand over the money at the Saltash Guildhall at a ceremony on Saturday.
She said she was delighted with the large amount raised.
£200,000 paid out
Mrs Hooper said the money has come mainly from local people, but she has also received donations from Devon and across the UK.
Councillor Graham Facks-Martin, the Chairman of Trustees for the North Cornwall Fund said the mayor's cheque brings the total fund to £380,000.
£200,000 has already been paid out to individuals and businesses in need of immediate help.
The floods on Monday 16 August caused millions of pounds of damage.
A 3m (10ft) wall of water crashed through the village when 77mm (3in) of rain fell in just a couple of hours.
