Wave barriers will be put up to prevent further coastal erosion, and a public transport system is also planned for Hua Hin.
Nalikatibhag said that success depended on the engagement of local residents and business operators.
"DASTA has so far won public support, as our main objective is to make sure that tourism development is sustainable and that benefits truly go to local communities," he explained.
The plan for Hua Hin and adjacent areas is supported by 96.31 per cent of local residents, he added.
