Areas disturbed by temporary facilities shall be restored to pre-construction condition to the satisfaction of the NMWC and the Contracting Officer.

The Riverside Irrigation Canal system (including associated laterals) is generally operated between April 1st and September 15th. Portions of this system are also operated intermittently year-round to maintain permanent plantings. The Contractor shall coordinate all system outages with NMWC.

System outages require significant pre-construction planning, communication with irrigation users, and preparation by NMWC operators. Temporary facilities may be required elsewhere in the system to allow for rerouting of flows and Contractor shall work with NMWC to facilitate. The Contractor shall develop specific plans for any planned system outages and obtain Contracting Officer and NMWC approval in advance of outages.

Unless specifically identified on the Plans or otherwise approved by NMWC, the Contractor shall not be permitted temporary access along the top of canal embankments, including equipment and material storage, parking, and staging. All temporary access shall be along the toe of embankments at field level. Where work encroaches upon canal embankments, the top of existing canal embankments shall be restored and re-leveled as required to provide the required freeboard above operating levels to the satisfaction of NMWC and the Contracting Officer.

Riverside Irrigation Canal

The Riverside Irrigation Canal is an existing irrigation main irrigation canal that parallels the SREL at the toe of the levee from downstream of Power Line Road to approximately I-80. The canal will be relocated landward to accommodate future levee construction activities. The canal is supplied with water from the Sacramento River at NMWC's Riverside Pumping Plant, just north of Radio Road, and re-circulated agricultural tailwater from a NMWC recirculation pump at RD1000's Pumping Plant No. 3. In addition to providing irrigation water to adjacent fields, the canal supplies lateral irrigation canals which serve properties to the east. To

DOCUMENT 00 73 05 Page 12 the extent practical, outages should be planned to occur outside of primary irrigation season. The work may be performed during peak irrigation season provided tie-ins are staged to avoid interruption of irrigation service.

Temporary piping and/or piping will be required to maintain service during tie-ins or for other outages. The Contractor shall provide temporary facilities (pumps, piping, etc.), make temporary connections, and operate the system to maintain irrigation flows. The plan for maintaining continuity of the irrigation flows during construction shall be developed by the Contractor in advance and is subject to approval by NMWC.
