Devon and Cornwall are to get £86m worth of flood defence works carried out across both counties over the next six years, the government has said.
The announcement is part of a £2.3bn nationwide flood defence programme.
In Cornwall, a new flood defence scheme in Perranporth costing £825,000 was to be built in an attempt to protect more than 200 properties in the area, officials said.
In Devon, Dawlish Warren, Exeter and Exmouth were to benefit, they added.
The plans, part of more than 1,400 flood defence projects listed for across the country - with 163 in South West England alone - would work "to bring peace of mind to residents and businesses", the government said.
Planned works include:
- A new flood defence scheme in Exeter costing almost £17m - supported by a £6m contribution from Devon County Council and Exeter City Council - to protect 4,150 properties in the area
- Work at Dawlish Warren and a beach management scheme at Exmouth designed to reduce flood risk to almost 3,000 homes and businesses
- An Exmouth tidal defence scheme to try and protect about 1,100 properties
Danny Alexander, the Chief Secretary to the Treasury, said the work was to help areas which "bore the brunt of terrible flooding earlier this year".
Labour accused ministers of "playing catch up on flood defences".
