Area transfer between Wiang Chai and Siri Wiang Chai municipality

Yesterday two announcements were published in the Royal Gazette which modified the boundaries between the subdistrict municipalities Wiang Chai (เทศบาลตำบลเวียงชัย) and Siri Wiang Chai (เทศบาลตำบลสิริเวียงชัย).
  • Modification of boundary of Wiang Chai municipality (ประกาศกระทรวงมหาดไทย เรื่อง เปลี่ยนแปลงเขตเทศบาลตำบลเวียงชัย อำเภอเวียงชัย จังหวัดเชียงราย) [pdf]
  • Modification of boundary of Siri Wiang Chai municipality (ประกาศกระทรวงมหาดไทย เรื่อง เปลี่ยนแปลงเขตเทศบาลตำบลสิริเวียงชัย อำเภอเวียงชัย จังหวัดเชียงราย) [pdf]
The sanitary district Wiang Chai was created in 1985 covering the area around the district office of Wiang Chai [Gazette]. It thus covered parts of the subdistricts Wiang Chai and Mueang Chum. The remaining parts of Wiang Chai subdistrict got its local government with the creation of the TAO Wiang Chai in 1997. 1999 the sanitary district - like all sanitary districts - became a subdistrict municipality. The TAO was upgraded to a subdistrict municipality effective September 6 2013, and had to be renamed to Siri Wiang Chai as the name Wiang Chai was already taken.

If I read the text of the announcements correctly, the administrative villages 1, 8, 9, 13 and parts of 19 get transferred from Siri Wiang Chai to Wiang Chai. Comparing the maps in the two new announcements with the one from 1985, its the southern boundary of Wiang Chai which gets changed from a straight line to a much more complicated shape by the added areas, also the northwestern boundary has been moved so it now same as the boundary between the subdistrict Wiang Chai and Wiang Nuea. There however remains one strange boundary - boundary point 6 cuts off a small area of Mueang Chum municipality from its main part, maybe to be simplified in a future boundary redefinition.

A more detailed description of this change should be found in the transcript for the meeting 33 of July 13 by the board 2 considering draft laws, but sadly the webserver seems to be misconfigured to be inaccessible outside Thailand, so I cannot read that file.
