§ 717. Boundaries and map of local government to which territory is
annexed. 1. Within a reasonable time after an annexation pursuant to
this article, the governing board of a local government to which
territory has been so annexed shall cause (a) a survey to be made of the
annexed territory, (b) the boundaries of the same to be marked with
monuments, and (c) a map to be made of such local government including
the annexed territory. In cooperation with the local government or
governments in which such territory was situated prior to such
annexation, it shall also cause a partial map to be made of such local
government or governments, which map shall be sufficient to show the
exclusion of such territory from such local government or governments.
Copies of such maps shall be filed in the office of the clerk of the
local government, in the office of the clerk of each county in which the
affected local governments are situated and in the office of the
secretary of state.
