Temporary construction activities meeting the following conditions of IDNR/OWR Statewide Permit Number 13:
(A) No temporary construction activity shall be commenced until the individual permittee determines that the permanent structure (if any) for which the work is being performed has received all required federal, state, and local authorizations;
(B) The term TEMPORARY shall mean not more than one construction season. All temporary construction materials must be removed from the stream and floodway within one year of their placement and the area returned to the conditions existing prior to the beginning of construction. Any desired subsequent or repetitive material placement shall not occur without the review and approval of the IDNR/OWR;
(C) The temporary project shall be constructed such that it will not cause erosion or damage due to increases in water surface profiles to adjacent properties.

(D) This permit does not authorize the placement or construction of any solid embankment or wall such as a dam, roadway, levee, or dike across any channel or floodway;
(E) No temporary structure shall be placed within any river or stream channel until a licensed professional engineer determines and documents that the temporary structure will meet the requirements of Special Condition Number 3 of this statewide permit. Such documentation shall include, at a minimum, confirmation that no buildings or structures will be impacted by the backwater induced by the temporary structure;
(F) The permittee shall maintain records of projects authorized by this permit necessary to document compliance with the above condition;
(G) Disturbance of vegetation shall be kept to a minimum during construction to prevent erosion and sedimentation. All disturbed areas shall be seeded or otherwise stabilized upon completion of the removal of the temporary construction; and
