three (3) locally collected willow stakes against the down hill side of the log. Each stake must <br /> be at least one and one half inches (1.5") in diameter, and must be at least two feet (2') in <br /> length. The stakes will be placed equidistant from each other against the logs on the down hill <br /> side, and will be pounded into the fill slope so that no more than six inches (6") of the stake is <br /> exposed above ground surface. <br /> Measurement and Payment <br /> Payment for construction of the rolled dips shall be at the unit price bid in Item 4 of the Bid <br /> Schedule per rolled dip constructed. Such payment shall be considered full compensation for <br /> all labor, materials, equipment and all other items necessary and incidental to the construction <br /> of the rolled dips. <br /> TASK 5: LOW WATER CROSSING CONSTRUCTION <br /> In a few locations, low water crossings will be constructed in order to provide access across <br /> some streams after culverts are removed. Map 4, Hydrologic Structures, shows the <br /> approximate locations of the low water crossings to be constructed. Low water crossings will be <br /> constructed upstream of the currently existing culvert locations in order that the road gradient is <br /> disrupted as little as possible. The low water crossings will essentially be access points <br /> constructed across an armored section of a stream channel. <br /> The stream banks at low water crossing locations will be excavated so that the access into and <br /> out of the stream does not be steeper than 4 H : 1 V. The width of the crossing (perpendicular <br /> to the flow of the stream) shall be twelve feet (12'). The material excavated from the stream <br /> slopes shall removed in such a manner so that material is not pushed into the creeks. The <br /> channel side cuts shall be excavated so that the cuts blend with the adjacent stream banks. <br /> Four to Six inch (4" - 6") diameter durable rock rip rap shall be placed from the base of each <br /> crossing to the crest of the ingress and egress to help protect the low water crossing from <br /> erosion. Figure 2, Low Water Crossing, depicts the construction specifications. <br /> For the Road C crossing of Dutch Creek, the 4 H : 1 V ingress and egress points will be <br /> constructed in the stream banks. The base of Dutch Creek at the point of the Low Water <br /> Crossing will not be altered. <br /> The following table lists the anticipated number of low water crossings to be constructed on <br /> each of the roads: <br /> Road Number of low water crossings <br /> B 3 <br /> C 6 <br /> D 7 <br /> Huntsman Ridge Road 2 <br /> Measurement and Payment <br /> Payment will be made at the price bid per low water crossing installed as specified. Payment <br /> will be made at the unit price established in Item 5 of the Bid Schedule. Such payment shall be <br /> 14 <br />
