Section 281.823. Bridge construction procedures.

(1) Each construction project shall be completed   so  as  to prevent erosion and subsequent damaging siltation of streams or lakes. The area of erodible land exposed to the elements by the grading operations at any one time shall be controlled by the owner's engineer and the duration of such exposure before final trimming, finishing, or maintenance of the area shall be as short as practicable.

(2)   Gravel or stone consisting   of  durable  particles  of   rock  and containing only  negligible  quantities  of  fines  shall  be  used  for construction pads, haul roads, and temporary roads in or across streams.

(3)     When required  by  the  department,   a  sedimentation   basin  shall  be constructed downstream from the work site to trap silt and sediment resulting from construction  operations.  A    detailed   sketch   of   a sedimentation basin is available on request from the department. The collected silt and sediment shall be removed as directed by the owner's engineer and the sedimentation basin shall be removed on completion of the project if directed by the department. If found necessary, the department may assist the owner in the design of a sedimentation basin.

(4)   The disturbance of lands and waters that are outside  the  limits  of construction as staked shall be avoided.

(5)   The owner shall give written notice 5 days before the start of work.
