FLOOD-protection measures funded by the government are to be installed in Bersted homes.
The properties are among the 40 most vulnerable in the county. They will have at least half of a £200,000 payment from the government spent on them to reflect this.
The money is included in a £298,500 grant from the Department of Environmental, Food and Rural Affairs to West Sussex to help communities become more resililent to flooding.
Flood action groups will also be formed in Bersted, Felpham and Shripney as part of the project.
These groups will consist of people with local expertise and knowledge of flood risks in their area who can work with the agencies responsible for flood prevention.
They will have the power to influence and change the way floods are managed.
The National Flood Forum will appoint a community officer to establish and support these groups.
The County Council’s cabinet member for residents’ service, Lionel Barnard, said: “This project is all about getting people to be more prepared for flooding.
“We want to help them understand their exposure to flood risk and inspire them to do something about it.
“We will also be protecting the homes of the most vulnerable in those places at greatest risk of flooding.”
“We want these improvements to act as a catalyst and encourage others to put them in.”
Operation Watershed, backed by £8.25m, has been started by the council to better prepare West Sussex against extreme weather.
A total of 68 parishes in the county will receive support to develop community emergency plans to help them next time flooding arises.
