1.3.48 SCR-49 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 RD1000 have agreed to certain in conveyance reductions to facilitate the project construction. The Contractor shall 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 shall 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 shall 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

DOCUMENT 00 73 05 Page 17 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 shall 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 at the Bennett Window. 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 NMWC will curtail all discharges from the Sankey and Bennett Main Canals into the Vestal Drain, and from the Sankey Canal into the NDC for the duration of the project. The Contractor shall obtain lockout/tagout clearances at gates and spills from Sankey Canal as required by their safety plans.

The Vestal Drain and its tributaries and drain inlet pipes are required to convey agricultural tailwater drainage flows through the work area during construction. The Bennett Main Canal flows must remain unimpeded by construction activities. The Contractor shall furnish, operate, and maintain temporary pumping and/or piping/ditching facilities as required to pass flows through the work area. Where flows are maintained by pumping, pump operation shall be continuously monitored, including after work hours. The tables below list the estimated maximum flows by month.

Maximum Irrigation Delivery Flow (cfs) per Month from Sankey Irrigation Canal to Bennett Main Canal

April May June July August September 46 65 71 98 50 13

Maximum Agricultural Tailwater Flow (cfs) per Month to the Vestal Drain

Vestal Drain Upstream of Work Area April May June July August September 0 40 20 20 20 20

Underdrain Outlet to Vestal Drain at Station 72+00 April May June July August September 0 15 4 4 4 4

During construction, NMWC will require access through the work area to both sides of the Sankey Canal and Bennett Main Canal. Coordinate sequencing of access routes with NMWC in advance.

Temporary haul road crossings over irrigation canals must be permitted

DOCUMENT 00 73 05 Page 18 through NMWC. Where crossings will employ culverts, they shall be sized for a conveyance area below the water line to provide velocities of less than 3 feet per second at the full design flows listed below:

" Sankey Canal upstream of Bennett Main - 420 cfs, " Sankey Canal downstream of Bennett Main - 320 cfs " Bennett Main Canal - 125 cfs.

Continuous safe access across the haul roads shall be maintained for the NMWC operator's patrol along the top of canal banks. Canal areas including patrol roads and landside areas shall be restored to NMWC's satisfaction.

No haul shall be allowed using the existing Sankey Canal crossings; however limited construction access for material/equipment deliveries and worker access may be allowed with prior coordination and post-construction restoration to NMWC's satisfaction.

North Drainage Canal: RD1000 will allow an outage of Pumping Plant 4 during the pumping plant relocation work. Cofferdams will need to be constructed to dewater the Pumping Plant 4 intake area, but the flows in the North Drainage Canal will naturally drain to the other pump stations in the Natomas Basin, so no temporary bypass of water from the North Drainage Canal to the Natomas Cross Canal is required. The only inflows that will require diversion are drainage from the area between the levee toe and the Sankey Canal, and from the new Vestal Drain. Cofferdams in the North Drainage Canal shall be designed for a 100-year design water elevation 20.0' NAVD 88 with a minimum of 1 foot of freeboard.

Natomas Cross Canal: In-water work in the Natomas Cross Canal(NCC) must be completed between 1 July and 30 September. Stages at the confluence with the Sacramento River are listed below:

Stage at Confluence of Sacramento River and NCC (NAVD88-ft) May June July August September High 30.0 25.4 23.3 15.2 13.8 Average 12.9 10.7 9.7 9.8 9.9 Low 5.6 5.1 4.9 5.1 5.9

Construction Water: A permit is required from NMWC to withdraw water for construction uses from ditches and canals within the construction area.

Water from irrigation canals which is supplied by pumping is limited by irrigation demands and must be regulated to assure reliable supply and avoid disruption to irrigation deliveries.

Contractor shall be responsible for obtaining all required permits from NMWC and scheduling the installation with NMWC.
