''If the buildings remain occupied, then police will act when the notice period expires,'' Mayor Ma-Ann said. ''It is our intention to demolish all of the buildings.''
Cherng Talay municipality followed orders from the military to clear all commerce from Surin and other beaches and beach foreshores after the Army took control of Thailand on May 22 last year.
All of the beach clubs and restaurants on the seaward side of a path that stretched the length of the beach were bulldozed but some well-known brands remained open and continued to operate on the other side of the path.
Catch, Bimi and Zazada are three names that have become famous as beach clubs at Surin with Taste, Pla, the Red Tablecloth, Salt and Twin Brothers among the restaurants that have continued to open and prosper.
The lucrative Surin businesses are not likely to close without a fight. Precise arrangements under which the shorefront businesses originally opened without action by local authorities remain unclear.
Catch Beach Club is regarded as Phuket's first beach club and it spawned a long list of imitators at Surin and other beaches.
The managers at the resorts around Surin say the beach will lose its present character without the beach clubs and restaurants.
Mayor Ma-Ann said today that a row of shops was constructed along the Surin shorefront to help locals recover after the 2004 tsunami - even though Surin beach was not seriously affected.
''Those buildings that remain occupied by the original recipients of the tsunami aid are possibly still legal,'' the mayor said. ''The rest are illegal.''
Questions are also being asked about a large new development at the southern end of Surin beach that appears to be embedded on rocks not far from the high-water mark.
