(b) Channel Restoration Performance.

Excavate the roadway fill in the existing draw to the width of the natural channel.

Excavate to the elevation of the original channel or the gradient of the pipe channel, whichever is lower. Slope the stream banks to match the original stream bank contours.

Place excavated material on the road prism against the back slopes along the roadbed.

Ensure that this material is free from slash and/or concentrations of woody debris, frozen soil, ice and snow. Contour the excavated material to match the adjacent slopes as

SHOWN ON THE DRAWINGS. Leave the recontoured slopes in an un-compacted condition.

Scatter slash and woody debris over the newly recontoured area.

Install gradient control structures perpendicular to the stream flow as SHOWN ON THE

DRAWINGS and as directed by the CO. Logs or rocks to be used for this purpose will be designated at or near the stream channel to be restored (the logs may require felling or bucking into the proper lengths). If an insufficient number of logs or rocks are available at a particular site, the CO can designate additional logs or rocks outside the riparian area to meet the contract requirements. Additional work may be performed under Section 622.

211.06 Removing Minor Culverts. Minor culverts and road fills where drainage has not been provided are to be removed as per Section 203. Minor culverts are defined as having less than

10 fit of road fill at centerline of road and diameter less than or equal to 48 inches. After removing the existing culvert and road fill, re-shape the roadbed as SHOWN ON THE
