Municipality area changes in Chiang Mai

Announced today was the change of area of the municipalities Chom Thong (เทศบาลตำบลจอมทอง) and Ban Luang (เทศบาลตำบลบ้านหลวง), both in Chom Thong district of Chiang Mai province. Though it was announced in two separate publication [Chom Thong, Ban Luang], in fact the two belong together as it was a transfer of area from Ban Luang to Chom Thong.

The reason for this transfer of area goes back to the creation of the sanitary district Ban Luang back in 1956 [Gazette], which at that time only covered the more densely populated area around the district office. In 1999 the sanitary district was upgraded to a municipality, in 2000 it was renamed to Chim Thong [Gazette], to have the same name as the district. In 2009 the TAO Ban Luang was upgraded to a municipality as well [Gazette], but since this covered the whole subdistrict area except those parts covered by Chom Thong municipality, this in fact meant that the municipality Ban Luang is split into two parts - the main part west of Chom Thong, and a small appendix east of it till the Ping River, which marks the boundary to Lamphun province. With these two announcements, this oddity is corrected, giving Ban Luang municipality a continuous area, and enlarging Chom Thong municipality to the west. Also a smaller area west of the original Chom Thong at the southern boundary of the subdistrict is added.

Sadly I have not enough time to create a map showing the old and new boundaries, so if you're interested in the details, there are maps are in the above linked announcements. The image above is from the 2009 TAO upgrade announcement, and shows Chom Thong hatched, and the subdistrict boundary by the thicker line.
