10. All erosion control measures shall be checked and maintained daily.

11. Maximum cut and fill slopes shall be two (2) foot horizontal to one (1) foot vertical, unless otherwise noted.

12. Erosion control measures will be maintained at all times. If full implementation of the approved plan does not provide for effective erosion control, additional erosion and sediment control measures shall be implemented to control or treat the sediment source.

13. The escape of sediment from the site shall be prevented by the installation of erosion and sediment control measures and practices prior to, or concurrent with, land-disturbing activities.
