The Code also provides that if a county has a department of public works or a public improvement agency (with the drain commissioner designated as the county agent), the county board of commissioners may, by a two-thirds vote, combine the duties of that department or agency with those of the office of drain commissioner into one county department headed by a public works commissioner. The bill would retain this authorization and the two-thirds requirement, but would strike language stating that the public works commissioner must carry out the powers and duties of the drain commissioner.
