In any county which has established a department of public works under the provisions of Act No. 185 of the Public Acts of 1957, being sections 123.731 to 123.786 of the Compiled Laws of 1948, the drain commissioner, if in his judgment any project in process of completion or which has been completed can more adequately or feasibly be handled by the department of public works, may file a written report to that effect with the county clerk. The report shall be filed in duplicate, and immediately upon receipt, a copy shall be forwarded to the department of public works and the clerk shall present the drain commissioner's recommendation to the board of supervisors at the next meeting. If the board of supervisors approves the drain commissioner's recommendation it shall, by resolution, so indicate and direct transfer of jurisdiction over the project to the department of public works. Any money which is in the drain fund of any district or belonging to such project at the time jurisdiction over it is transferred shall be promptly transferred and used by the department of public works for the purpose for which it was accumulated. All assets, files, maps, drawings, specifications, records of procedure, assessment rolls or other data pertinent to the project shall be transferred to the department of public works. Thereafter, the department of public works shall be responsible for further proceedings and the drain commissioner relieved therefrom.
