1. BEGIN AT THE LOCATION WHERE THE WATTLE IS TO BE INSTALLED BY EXCAVATING A 3" DEEP X 9" WIDE TRENCH ALONG THE CONTOUR OF THE SLOPE. EXCAVATED SOIL SHOULD BE PLACED UPSLOPE FROM THE

ANCHOR TRENCH.

2. PLACE THE WATTLE IN THE TRENCH SO THAT IT CONTOURS TO THE SOIL SURFACE. COMPACT SOIL FROM THE EXCAVATED TRENCH AGAINST THE WATTLE ON THE UPHILL SIDE. ADJACENT WATTLES SHALL BE

OVERLAPPED 24", NOT ABUTTED.

3. SECURE THE WATTLE WITH 24" STAKES EVERY 4' AND WITH A STAKE ON EACH END. STAKES SHOULD BE DRIVEN THROUGH THE MIDDLE OF THE WATTLE LEAVING AT LEAST 2-3" OF STAKE EXTENDING ABOVE THE

WATTLE. STAKES SHOULD BE DRIVEN PERPENDICULAR TO THE SLOPE FACE.

2. OSHA Requirements:

Follow Occupational Safety and Health Administration (OSHA) safety regulations or OSHA approved state plan requirements as required.

3. Submittals:

A. Traffic Control:

Traffic control devices for all activities, including full and partial road closure, shall be maintained as needed for safe operations. The Contractor shall submit for approval by the CO, a traffic control plan prior to beginning work. The plan shall conform with Ohio Department of Transportation requirements and the most recent edition of the Manual on Uniform Traffic Control Devices. The Contractor shall provide and maintain all necessary devices and signs.

B. Erosion Control:

Prior to the starting work, submit a written Erosion Control Plan that provides permanent and temporary erosion control measures to minimize erosion and sedimentation. Do not begin work until the necessary controls for that particular phase of work have been implemented. Do not modify the type, size, or location of any control. An alternate erosion control plan with all necessary permits may be submitted 5 days before intended use. Incorporate all permanent erosion control features into the project at the earliest practical time, as outlined in the approved plan. When erosion control measures are not functioning as intended, immediately take corrective action. Payment for erosion control and the erosion control plan is included in Pay Item 003 .

C. Schedule:

Prior to starting work, submit a detailed schedule that incorporates all work activities and describes the sequencing of work items.

D. Products and Materials:

Submit product and material documentation, as required in the specifications for approval prior to purchasing and/or delivering to the site.
