A. The contractor and permittee or project owner shall be responsible for continual maintenance of all erosion control devices during the rainy season as specified in the Grading Manual. The director may require that erosion control be maintained at other times outside the rainy season. In the event of failure or refusal by the contractor, permittee or project owner to properly maintain the devices, the director may cause emergency maintenance work to be done to protect adjacent private and public property. The cost shall be charged to the owner and shall include an initial mobilization cost plus the cost of doing the work as provided in Section C7-54. B. In the event the director must cause emergency maintenance work to be done, he or she may revoke the grading permit in writing. The permit shall not be renewed until an erosion control system approved by the director is installed, payment for costs incurred by the city have been made and a fee of one-half the amount required for the original permit paid by the owner. The director may waive installation of an erosion control system after April 15th. C. If any grading subject to Section C7-12 has commenced on private property without a valid grading permit, the property owner may be required to prepare and implement an erosion control plan approved by the director. Compliance with this provision does not relieve the property owner from responsibility or liability for the grading violation. If the property owner fails to install the approved erosion control system by October 15th, the director may cause emergency work to be done to protect adjacent private and public property during the October 15th through April 15th winter season. The procedures of Section C7-28 shall not apply to such emergency work. Cost of the emergency work shall be charged to the property owner in accordance with subsections A and B above. (Ord.
