When the construction or reconstruction of a township road or bridge, the insertion of a culvert in a township road, or the construction or reconstruction of a ditch or drain in connection with a township road affects the flow of surface waters and increases the surface waterflow through ditches, drains, bridges, and culverts in other townships, the board of township supervisors or the township overseer of highways of the township undertaking the construction or reconstruction shall give notice to the boards of township supervisors or township overseers of highways in all townships affected by the construction or reconstruction projects.
The boards of township supervisors of townships affected by any road or bridge construction that changes or increases the flow of surface waters shall cooperate in the construction projects expending on any portion of the projects the portions of the road and bridge tax as deemed conducive to the interests of the township. The board of township supervisors shall construct the ditches, drains, bridges, and culverts in accordance with stream crossing standards prepared by the department and the department of water resources. A township, board of township supervisors, and township overseer of highways are not liable for any damage caused to any structure or property by water detained by the highway at the crossing if the highway crossing has been constructed in accordance with the stream crossing standards prepared by the department and the department of water resources.
