Straw bales, certified as weed free or weed seed free (see the requirements of Task <br /> , Revegetation) shall be placed adjacent to each stream at the base of each side slope <br /> created during performance of this Task. A trench measuring four inches (4") deep, by <br /> the width of the bales, by the length of the side slope cuts shall be excavated at the <br /> base of each side slope cut. The base of the trench shall be smooth and free of large <br /> rock so that the bales may be placed in direct contact with the ground surface. Each <br /> bale shall be anchored using two wood stakes per bale. The bales shall be placed so <br /> that any one bale is in direct contact with the adjacent bale (s). <br /> Measurement and Payment <br /> There will be no measurement for payment. Payment for this task will be reflected in a lump <br /> sum bid under Item 3 on the Bid Schedule. This lump sum bid will cover all costs for excavation, <br /> removal and disposal of the culverts, excavation of the side slopes and channel bottom, and <br /> placement of straw bales. Payment shall be as this task is completed and approved by the <br /> PROJECT MANAGER. Such payment shall be considered full compensation for all labor, <br /> materials, equipment and all other items necessary and incidental to the completion of Task 3, <br /> Culvert Removal. <br /> TASK 4 EARTH WORK <br /> The earth work portion of this bid involves reclamation of the eastern most portion of <br /> the Rock Tunnel back wall. The material excavated during performance of Task 3, <br /> Culvert Removal will be transported to the back wall for use as backfill material for the <br /> purpose of covering the demolished concrete rubble, and to create a shallow back fill <br /> slope. <br /> The targeted height of backfill is twenty five feet (25'), and the approximate length of <br /> highwall to be backfilled is 100 feet. The PROJECT MANAGER shall mark the <br /> targeted backfill height and the east and west margins of the backfill area using spray <br /> paint or other suitable means. All rubble and debris placed adjacent to the back wall <br /> shall be buried during completion of this task by no less than four feet (4') of earthen <br /> materials. <br /> Backfilling shall occur so that the earthen materials excavated from the Dutch Creek <br /> Culvert, in conjunction with the material excavated from the hole dug at the base of the <br /> back wall during performance of Task 2, Demolition, is used initially, or as the core of <br /> the backfill. The backfilled slopes shall be compacted every two feet (2') by sheep's <br /> foot roller. The material excavated from the Road E culvert is of better quality, and <br /> shall be used as cover over the previously placed materials. Backfilled slopes shall not <br /> exceed 2.5H:1 V upon completion of operations. <br /> Amendment of the backfill cover material and surface roughening will be accomplished <br /> during performance of Task , Revegetation. <br /> Measurement and Payment <br />
