The principal components of the work to be performed under the specifications include the following: A. General Requirements - Administrative requirements, procedural requirements, temporary facilities, and controls which apply to the execution of work. B. Schedule A - Schedule A of Phase II of the American River Pump Station project consists of Primary and Emergency river intake structures, an Obermeyer-type maintenance gate, channel and cofferdam grading, channel erosions protection measures including grouted rock and riprap, intake structure access roads and surfaces, hatches up to 8 feet by 12 feet in size, air and water piping from the pump station to the intake contained in a utility trench and a concrete-encased 48-inch diameter casing pipe beneath the river for future extension of the 30-inch diameter GDPUD pipeline from the pump station to the south side of the river. The river intake structures will provide water to the American River Pump Station constructed under Phase I and are to be constructed on the north bank of the American River channel directly beneath the pump station. 1. Primary Intake Structures - The Primary Intake structure consists of a reinforced concrete and grouted boulder chute with tilted, wedge-wire intake screens and air backwash. Collection chambers beneath the screens deliver diverted water to six 30-inch diameter reinforced concrete pipes. The concrete pipes carry diversions to the Intake Vault at the existing pump station tunnel entrance and are controlled by manually operated knife-gate valves. 2. Emergency Intake Structure - The Emergency intake will consist of a coarse bar screen divided into four separate chambers. Each of the four chambers discharges to a concrete box collection conduit behind the intake through various sized openings. The collection conduit varies in size from 3.5 foot by 3.5 foot to 6 foot by 6 foot. Flows collected in the collection conduit are controlled by a manually operated 6 foot by 6 foot cast iron sluice gate. The sluice gate discharges to a maintenance and sedimentation vault which in turn discharges to a 7 foot by 7 cast-in-place Emergency Intake Conduit. The Emergency Intake conduit extends approximately 80 feet to the Intake Vault at the existing pump station tunnel entrance. 3. Maintenance Gate - A 16 foot wide by 9 foot high Obermeyer-type maintenance gate is located between the Primary and Emergency Intakes. The gate will allow river flows less than 2,500 cfs to be diverted away from the Intake Channel to facilitate maintenance work. 4. Channel Modifications - Channel modifications will consist of grouted rock and riprap lining of an approximate 900 foot reach of the American River channel at the location of the intake structures and additional riprap protection of the cofferdam for another 900 feet upstream. A 30-foot depth cutoff wall extends approximately 220 feet across the channel at the entrance to the intake area. In addition to the grouted rock protection, channel modifications will include construction of a new channel cross section through plug areas located at the tunnel entrance and exit. 5. Air and Water Piping - Air and water piping will extend from the pump station a distance of approximately 140 feet down the valley side to the Intake Vault structure. Piping will include: a. 4- to 8-inch diameter ductile iron, steel and stainless steel lines for air backwash of the Primary Intakes; 2-inch diameter stainless steel pipe for inflation of the Obermeyer Maintenance Gate; 6-inch diameter ductile iron line for washdown at the intake: 1/2-inch diameter nylon tubing in 6-inch PVC carrier pipe for actuation of backwash system pneumatic butterfly valves; 1/4-inch diameter tubing contained in carrier pipes for level sensing and flushing of stilling wells; additional 6-inch PVC carrier pipes for future use. All of the above located in an excavated rock trench between the Pump Station Vault and the Intake Vault backfilled with flowfill. Trench conditions below the Intake Vault vary. b. 6 pneumatically actuated butter fly valves located in the Intake Vault controlled by 6 solenoid valves located in the Pump Station Vault and linked to a SCADA system. 6. Intake Access - Access to the top surfaces of the intake structures and Obermeyer Gate for maintenance work will be provided by a drive-down access road. Access to the interiors of the Emergency Intake and the Intake Vault will be provided through hatches up to 8 feet by 12 feet in size. The largest hatches are intended to allow both a skidsteer and a large sediment bin to be lowered into the structure. The bin could be used in combination with a skid-steer to remove accumulated sediment. 7. GDPUD Pipeline - A 48-inch diameter concrete encased casing pipe is to be constructed across the river channel upstream of the Emergency Intake. The casing pipe will provide for future construction of the proposed 30-inch diameter GDPUD steel pressure line currently stubbed out at the Pump Station east wall. C. Schedule B - Schedule B of Phase II of the American River Pump Station project consists of closure of the river diversion tunnel inlet and outlet; a diversion access road; and the Public Access Components of the project. The Public Access Components consist of a park entrance building, parking areas and turnarounds, improvements to access roads, and construction of a new trail. 1. Closure of the River Diversion Tunnel - The inlet and outlet of the existing 33-foot diameter horseshoe shaped diversion tunnel will be closed. The inlet closure shall consist of sheet piles linked together and supported at the top and bottom to cover the tunnel opening. The entrance will then be backfilled to cover the face of the sheet piles. The tunnel outlet shall be closed with rock fill. The rock fill shall be allowed to fall into its natural angle of repose inside the tunnel. The outside rock fill slope shall not exceed two horizontal to one vertical. Approximately 1,520 square feet of sheet pile and 8 cubic yards of concrete will be required for closure of the tunnel inlet. Approximately 9,000 cubic yards of rock fill will be required for closure of the tunnel outlet. 2. Diversion Access Road - An access road shall be constructed from the existing pump station site to the intake structure in schedule A. The access road shall be concrete over an aggregate base and the work will include guardrail and drainage facilities. Total length of road to be constructed is approximately 552 feet. 3. Park Entrance Building - A 10-foot by 22-foot, single story, block masonry building will be constructed just off Maidu Drive at the entrance to the park. The building will have water and electrical service. A precast concrete sanitary vault will be installed to provide sewer service for the building. 4. Parking Areas and Turnarounds - A paved and striped parking area, consisting of approximately 15 spaces (1 ADA), will be constructed just off Maidu Drive. The parking area will include a drinking fountain, trash containers, and a kiosk. A second parking area, consisting of a paved and striped parking area consisting of approximately 50 spaces (2 ADA), will be constructed at the existing Auburn Dam Batch Plant site just above Oregon Bar. The parking area will include bathrooms, trash containers, and a kiosk. Fencing shall be placed around the existing ponds in this area. Construction of the Maidu and Batch Plant parking areas will consist of minor grading for drainage purposes. A third parking area will be constructed solely for ADA access near the river channel on a rock bench approximately 1,200 feet Northwest of the existing diversion tunnel outlet. The gravel ADA parking area will be approximately 80 feet by 80 feet. A gravel road approximately 520 feet long and 15 feet wide will be constructed from an existing road to the ADA parking area. A turnaround area, to be used by the Department of Parks and Recreation and emergency vehicles, will be constructed next to the river channel approximately 100 feet Northeast and down grade from the ADA parking area. The gravel turnaround will be approximately 30 feet by 50 feet. The ADA parking area, ADA access road, and turnaround area will require rock and common soil excavation. Another gravel turnaround will be constructed near Oregon Bar. The turnaround will be approximately 50 feet by 50 feet. Construction of this turnaround will consist mainly of grubbing existing shrubs and some minor grading. 5. Improvements to Access Roads - Approximately 6,900 linear feet of 24-foot wide existing paved road between Maidu Drive and the Batch Plant parking area will be improved by overlaying the entire width of the existing paved area. Approximately 4,200 linear feet of 24-foot wide existing dirt road between the Batch Plant parking area and river turnaround will be improved. The improvements will consist of grading to smooth the road and then installing a gravel base. Approximately 4,450 linear feet of 15-foot wide existing dirt road between the Batch Plant parking are and the Oregon Bar take-out area will be improved. The improvements will consist of grading to smooth the road and then installing a gravel base. Culverts will also be installed along the road to provide adequate drainage. 6. Trail - A 4-foot wide trail, approximately 3,920 linear feet, will be constructed between the Batch Plant parking area and the Oregon Bar turnaround area. The construction of the trail will consist of removal of boulders, grading and grubbing. Also, drainage facilities such as culverts and bridges shall be constructed along the trail. The total length of trail to be constructed is approximately 3,920 feet.
