"The following construction requirements shall apply:

a.- Earthwork. Clearing and grubbing, excavation, borrow and embankment operations shall be scheduled and performed so that grading operations and permanent erosion control measures can follow without interference or be constructed within the time periods listed in Table 204.1.

b.- Stream Courses. Temporary culvert installations will not be permitted in live streams unless approved individually in writing by the Engineer. If such approval is granted, temporary culverts shall be offset a sufficient distance so that installation of the permanent culvert can be completed without removal of the temporary culvert. Temporary culverts shall not be removed until flowing water is completely confined to the permanent culvert.

Diversion of live streams to allow work in the streambed shall be performed in such a manner as necessary to prevent erosion. Dikes of sufficient height to divert the flow without being overtopped shall be constructed in the stream above the drainage structure. Water shall be conveyed around the work area by a non-eroding conduit. Watertight pipes, tubing, or lined trenches may be used. Trench or pipe outlet areas shall be protected with plastic or other material approved by the Engineer to insure that diverted water does not cause erosion as it returns to the stream.

SPS 204-2 (3/1/10)

Equipment shall not operate in the stream unless authorized by the Engineer. This does not include a one time crossing of the stream to begin installation. After installation of the permanent drainage structure is completed, all dikes, temporary culverts, basins, and trenches shall be removed and the area restored to near natural condition. Other methods may be used when approved by the Engineer.

c.- Wet Conditions. The contractor shall conduct operations so as to minimize erosion and not develop conditions that will cause erosion. Work may continue during wet conditions as long as erosion and rutting is controlled.

d.- End of Construction Season and prior to Move-out. Any rutted areas and other damaged areas shall be smoothed, sloped and graded to drain. All temporary stream course diversion conduits and temporary culverts shall be removed and the stream returned to its natural channel. All erosion control measures required under this specification shall be functional and approved by the Engineer. The seeding method prescribed in Section 625 shall be used on all areas where work has been completed.

e.- Slash Blanket. Tops and limbs shall be windrowed or piled in openings outside the roadway without damage to the standing timber. After Item 203 - Excavation & Embankment is essentially complete and approved by the Engineer, slash (tops and limbs) shall be uniformly scattered on the embankment then compressed with a backhoe or other mechanical means to form a protective blanket to reduce soil erosion.

f. Use certified weed free straw bales for erosion control. Break apart bales and scatter in loose layers no more than 2” thick after work is completed.
