The Sutey Stream Diversion is approximately 1240 feet in length, and will be trapezoidal in shape. This diversion will be constructed at the location of the currently existing diversion channel. Large rock encountered in the channel during excavation of the Sutey Stream Diversion shall be removed from the channel, and stockpiled near the bottom of Ditch 8 in a location to be specified by the PROJECT MANAGER. The bottom of the channel shall be no less than seven (7) feet in width. Side slopes will be excavated at a 2H:1 V angle. The depth of the channel will be no less than 1 .8 feet as measured from the base of the channel to the crest of the side slopes (Cross Section 4). The channel depth will be approximately three feet (3') greater near the upper reaches of the diversion. The diversion will require additional armoring through a bend. For a length of not less than 40 feet beginning at about 90 feet below the upper extent of the diversion, the channel will be rip rapped with durable materials having a D50 of three (3) feet. Additionally, the outside bank of the diversion will be increased in height to four (4) feet through this reach. The depth will be measured from the bottom of the channel to the crest of the outside edge of the channel. After excavation of the channel is completed, the entire length of the diversion will be broadcast seeded with the Sutey Diversion Mixture at a rate of sixty (60) pounds per acre. The seed will be provided by the PROJECT MANAGER. The entire Sutey Stream Diversion length, excepting the riprapped portions, shall be lined with fabric which will consist of a natural material such as coconut fiber sewn between two ultra-violet stabilized nets. The fabric shall be installed as per manufacturers specifications. The Spring Conveyance Ditch, which will convey flow from a spring adjacent to the Sutey Refuse Disposal Area, will be constructed near the upper reaches of the Stream Channel Diversion. This channel will be approximately 300 feet in length, and will be constructed to the specifications of Ditches 2, 3, 4, 5, 6, 7 (Cross Section 1), except that no liner is required. The Spring Conveyance Ditch will flow into the Stream Channel Diversion approximately 500 feet below the beginning of the Stream Channel Diversion. Measurement and Payment Surface drainages will be measured to the nearest linear foot. Payment for this task will be paid for at prices established in Task 4, sub-tasks a through j on the Invitation and Bid sheet per linear foot installed. Such payment shall be considered full compensation for all labor, materials, equipment and all other items necessary and incidental to the furnishing of all materials and construction of the Surface Drainages as directed and described in the specifications, including seeding. Payment will be as this task is completed and approved by the PROJECT MANAGER. Payment for this task will be made only for the unit price shown under Task 4, sub-tasks a through j, of the Bid Schedule. TASK 5 EQUIPMENT RENTAL Additional areas adjacent to the refuse disposal areas may require slope reduction, excavation or erosion control work. A CAT D-7H or equivalent 215 FHP machine with operator, a CAT 416B Backhoe loader or equivalent 74 fhp machine with operator, and a five (5) cubic yard on/off highway dump truck with operator shall be furnished for additional work as needed. The hours outlined in Task 5 of the Bid Schedule are NOT guaranteed. All work will be accomplished according to Specification 19.0, Equipment Rental, attached. 10
