In meeting number 21 from April 22 2010 of the board to consider draft laws the only topic was the proposed upgrade of subdistrict municipality Laem Chabang (เทศบาลตำบลแหลมฉบัง) to a city municipality (เทศบาลนครแหลมฉบัง). The term of the municipal council ends on May 13, therefore municipal elections have to be held within the next 60 days anyway, so it is a good time to do a status change without the need of an extra election being held.
This upgrade probably means that the special administrative area Laem Chabang, which I have found mentioned elsewhere before, has been shelved for the moment.
The subdistrict municipality Laem Chabang was created in 1991 [Gazette], and is one of only a handful of municipalities which spread on more than one district, as it covers parts of both Bang Lamung and Si Ratcha district. Since the deep water harbor and the industrial area around it belongs to this municipality, it has quite a solid tax income and should have been eligible for a higher municipal status before already.
