10-1.02B Traffic Elements
Before starting the operational test of a traffic management system that di rectly impacts traffic, the system must be ready for operation, and all signs, pavement delineation, and pavement markings must be in place at the system's location. If maintaining existing traffic management system elements during construction is shown on the Bid Item List, a list of the systems shown within the project limits and their operational status is included in the Information Handout . Before starting job site activities, conduct a preconstruction operational status check of the existing system's elements and each element's communication status with the transportation management center to which it communicates. If an existing system element is discovered and has not been identified, the Department adds the element to the list of systems. The pre -and postconstruction operational status check of the discovered elements is change order work. If maintaining existing traffic management system elements during construction is not shown on the Bid Item List and an existing system element is discovered duri ng the work, notify the Engineer. The Engineer orders a pre -and postconstruction operational status check of the discovered elements. The status check of the discovered elements is change order work. Conduct the status check with the Engineer and an elect rical representative from the traffic operations office of the district in which the work is located. The Department provides you a list of the preconstruction operational status -check results, including:
1.Existing traffic management system elements and their locations within the project limits
2.Fully functioning elements
3.Nonoperational elements Before Contract acceptance, conduct a postconstruction operational status check of all elements shown on the list with the Engineer and an electrical repres entative from the traffic operations office of the district in which the work is located.

10-1.02C(2) Irrigation Facilities
Upon discovering an irrigation facility not described in the Contract, immediately notify the Engineer. The Engineer orders the locating and protecting of the irrigation facility. The locating and protecting is change order work.

10-1.02D Traffic Stripes, Pavement Markings, and Pavement Markers
Before obliterating any traffic stripes, pavement markings, and pavement markers to be replaced at the same location, reference the stripes, markings, and markers. Include limits and transitions with control points to reestablish the new stripes, markings, and markers. Submit your references to the control points at least 5 business days before obliterating the stripes, markings, and markers. SECTION 1 0 GENERAL
10-1.02E Excavation
If a difference in excess of 0.15 foot exists between the elevation of the existing pavement and the elevation of an excavation within 5 feet of the left edge or within 8 feet of the right edge of the traveled way at the end of each working day, place and compact material against the vertical cut adjacent to the traveled way. During the excavation, you may use native material for this purpose except you must use structural material once you start placing the structural section. Place the material to the top of the existing pavement and taper at a slope of 4:1 (hor izontal:vertical) or flatter to the bottom of the excavation. Do not use treated base for the taper.

10-4 Water Usage
Section 10 -4 includes specifications for using water for construction activities. The Department encourages you to conserve water in all construction activities. The Engineer notifies you of any ( 1) water shortage or (2) mandate from a local water authority to ration water. Within 10 days of the notification, submit a water conservation plan. The plan must include:
1.List of construction activities that require water
2.Measures you will implement for each activity to conserve water
3.Method for curing concrete other than the water method if included in the work
4.Dust palliative you will use for dust control
10-5 Dust Control
Section 10 -5 includes specifications for controlling dust resulting from the work. Prevent and alleviate dust by:
1.Applying a dust palliative under section 18
2.Applying temporary soil stabilization under section 13 -5
3.Managing material stockpiles under section 13 -4.03C(3)
10-6 Watering
Section 10 -6 includes specifi cations for developing a water supply, furnishing water, and applying water. Developing a water supply includes developing a supply of water and furnishing pipes or other equipment needed to convey the water to the water application equipment. Water may be potable or nonpotable. Nonpotable water must be either recycled water or nonpotable water developed from other sources. The sources and discharge of recycled water must comply with the water -recycling criteria of the CDPH, SWRCB Order No. WQ 2016 -0068 -DDW, and the requirements of the appropriate RWQCB . Obtain either a waste discharge permit or a waiver from the appropriate RWQCB for each water source. Submit a copy of the permit or waiver before using the water in the work. If an available sou rce of water is described in the Information Handout , verify the quality and quantity of water. Nonpotable water must not be conveyed in tanks or drain pipes that will be used to convey potable water. Nonpotable water supplies and potable water supplies mu st not be connected. Nonpotable water supply, tanks, pipes, and other conveyances of nonpotable water must be labeled Nonpotable Water / Do Not Drink. SECTION 1 0 GENERAL Each water storage tank and distribution system must be equipped with positive shut -off valves. Keep at l east 1 mobile unit with a capacity of at least 1,000 gal the job site at all times for applying water unless all water is applied through pipes or another authorized method. For compacting embankment material, subbase, base, and surfacing material and for dust control, apply water with equipment that will apply it uniformly. For compaction, you may use a chemical additive if authorized. If a bid item for develop water supply is shown on the Bid Item List, the Department does not adjust the lump sum price fo r any increase or decrease in the quantity of water required or for change order work.
