After the consolidation is effective, statutes relating to highway districts shall be applicable to the joint consolidated highway district, except as otherwise provided in this chapter. The assessing of property, the levying and collection of ad valorem taxes and all accounts which from their nature should be separately kept, shall be done and kept and the report on them made as if each portion of the consolidated district were a separate highway district in the respective counties. Nothing in this chapter shall be construed as preventing the new highway district board from levying ad valorem taxes against property within the consolidated district in accordance with chapter 8, title 40, Idaho Code.
