1.3 SUPPLEMENTARY CONDITIONS REQUIREMENTS

1.3.1 SCR-1 Location of Work

The Natomas Basin is approximately 53,000 acres (82 square miles) and is situated north of downtown Sacramento. Reach D is situated along Natomas Cross Canal at the north side of the basin. The eastern limit of the Vestal Drain connects into the North Main Drainage Canal which drains into Pumping Plant 4. The borrow stockpiles are located at the western limit of the Vestal Drain. There are no volume surveys for these stockpiles, but the approximate volume of the northern stockpile is 20,000 cubic yards, and the approximate volume of the southern stockpile is 27,000 cubic yards. The Soil Testing Summary Table for the northern stockpile is attached to the back of Section 31 00 00 EARTHWORK.

1.3.2 SCR-2 Scope of Work

The work includes removal of the existing Pumping Plant 4 building and trashrack, and reconfiguring the pump station intake and installing a new

DOCUMENT 00 73 05 Page 3 trash rack. Pumping Plant 4 must remain operational until April 1, 2021.The pump station pad will be raised and have new pumps installed, but will not include a new building. A driveway to the new trash rack will also be constructed. A new Electrical Building located west of the existing Pumping Plant 4 will be constructed housing all of the new electrical controls. A transformer and concrete pad will also be located adjacent to the Electrical Building, with power provided from the adjacent PG&E lines. Six-foot high chain-link fencing will enclose the Pumping Plant area, with gates installed as shown on the plans. Access ramps and landside toe roads will be reconfigured to accommodate the new pumping plant layout.

The project also includes replacement of Pumping Plant 4 with outlet pipes to be relocated through the levee at an elevation above the 200-year water surface elevation. Modification of these pipe works will require degrade of the levee to an elevation just above the existing cutoff wall. The existing 48" pipes will be removed and replaced with new pipes, but the Contractor may use the existing low head reinforced concrete pipes purchased and stockpiled by SAFCA in 2009 if they meet specification requirements. RD1000 has approximately 430' of 48" diameter pipe including fittings stockpiled. The low head reinforced concrete pipes were manufactured by Hanson Pipe and Products, Inc. The Contractor must supply new gaskets and incidentals necessary for the complete installation of the RD1000 pipes. Additional materials including pipes, 600 and 450 HP pumps, trashrack and trashrake, and valves are located in the RD1000 Maintenance Yard. The Contractor is responsible for the loading, trucking, and shipping fees incurred for delivering the Government furnished items to the construction site. The Pumping Plant 4 Equipment receipts are attached to the end of this section

Below is the list of Government furnished items stored at the RD1000 Maintenance Yard (Elkhorn Boulevard near Garden Highway):

1.3.47 SCR-47 Natomas Mutual Water Company and Reclamation District 1000 Operations

The Natomas Mutual Water Company (NMWC) owns and operates raw water irrigation distribution facilities along the existing levees throughout the project area. Reclamation District 1000 (RD1000) owns and maintains the drainage canals that convey storm water runoff during the winter months and agricultural drainage during the summer months. During the irrigation season, NMWC, through joint use agreement with RD1000, operates and maintains the drainage canals used for irrigation conveyance, including the Vestal Drain and the North Drainage Canal (NDC). NMWC and

DOCUMENT 00 73 05 Page 18

RD1000 have agreed to certain conveyance reductions to facilitate the project construction. The Contractor must coordinate its work with NMWC and RD1000, allowing access to their facilities as required for unimpeded operations.

RD1000 operates Pumping Plant No. 4 (PP4) for pumping drainage water (storm water during the winter and agricultural tailwater during the summer) from the NDC out of the Natomas Basin into the Natomas Cross Canal. RD1000 will provide a PP4 outage for the duration of the project.

During construction, the Contractor must facilitate RD1000 access through the work area to both sides of the NDC for patrol and maintenance, unless limited outages are obtained during non-critical periods. The Contractor must be responsible for conveying all drainage water through the project area to the NDC south of any work limits. This generally includes:

- Vestal Drain and its tributary flows (drainage and agricultural tailwater) that outfall into the NDC immediately upstream of PP4.

- Drainage runoff from the area between the levee toe and Sankey Canal to the east of PP4 that outfalls upstream of PP4.

- Direct inflows from storm water runoff and seepage.

During the summer, any backup of water in the Vestal Drain will result in flooding of upstream fields and roadways, interrupting farming operations and potentially damaging crops and will not be permitted. The Vestal Drain and all its inlet and outlet facilities must be fully operational to convey drainage flows prior to November 1. The drainage outfall from the east must be extended through work area to the NDC for gravity outlet prior to November 1.

NMWC owns and operates the Sankey Irrigation Canal which parallels the Natomas Cross Canal south levee, and the Bennett Main Canal which is aligned normal to the Sankey Irrigation Canal. The Sankey Diversion Pumping Plant provides supply from the Sacramento River for the Sankey Irrigation Canal. The Bennett Main Canal is served from the Sankey Irrigation Canal.. The Sankey Irrigation Canal flows must be maintained through construction.

The Vestal Drain and its tributaries and drain inlet pipes are required to convey agricultural tailwater drainage flows through the work area during construction.

During construction, NMWC will require access through the work area to both sides of the Sankey Canal and Bennett Main…
