During the wet season, slopes and stockpiles 3H: 1V or steeper, and with more than ten feet of vertical
relief shall be covered if they are to remain unworked for more than 12 hours.

-Cover methods include mulch, erosion control nets and blankets, plastic covering, seeding, and sodding. —----
-Temporary erosion and sediment control measures will be inspected prior to any clearing or grading
during and at the completion of the project. It is the responsibility of the applicant to maintain erosion
control measures in proper working condition to insure that no sediment is leaving the site.
-If, in the opinion of the Erosion Control Inspector, the temporary erosion control measures are not
installed, are installed incorrectly, or are in need of repair, a Stop Work Order may be issued until
corrective action is taken. If a reinspection is necessary, a reinspection fee will be charged.
