The Contractor shall repair or replace, at no additional cost to the owner, all Items damaged by his work. The Contractor shall coordinate his work with other contractors for the location and Installation of pipe sleeves and laterals through walls, under roadways and paving, etc. 2. The Contractor shall not willfully install the Irrigation system or shown on the drawings when it is obvious In the field that unknown obstructions, grade differences, or differences in the area dimension exist that might not have been addressed In the design of the Irrigation system. Such obstructions or differences shall be brought to the attention of the Owner's authorized representative. In the event this notification Is not performed, the Contractor shall assume full responsibility for any necessary alterations to the work. 3.

The Contractor shall be responsible and liable for any encroachment into adjacent property, R.O.W.'s easements setbacks or any other legal property restrictions either marked or unmarked. 5. The Irrigation system design is based on a minimum operation pressure of 60 PSI a maximum operation pressure of 70 PSI and a maximum flow demand of 21.8 GPM. The Contractor shall verify water pressure prior to construction. Report any difference between the water pressure Indicated on the drawings and the actual pressure reading at the Irrigation point of connection to the Landscape Architect. 6. This design Is diagrammatic. All piping, valves, etc., shown within paved areas Is for design clarification only and shall be Installed In planting areas wherever, possible. The Contractor shall locate all valves in shrub or groundcover areas. 7. Trenching within the dripline of large existing trees shalt be performed by hand, and with extreme care not to sever roots 1-1/2' In diameter and larger. Where roots 1-1/2' In diameter and larger are encountered, the Contractor shall tunnel under said roots. Exposed roots that have been tunneled under shall be wrapped In wet burlap and kept moist while the trench Is open. 8. All main In piping, lateral line piping, and control wires under paving shalt be Installed in Schedule 40 PVC sleeves at a minimum depth of 18'. Sleeves shall be Installed before paving is in place. All sleeve sized shall be a minimum of twice the diameter of the pipe to be sleeved. Control wire sleeves shall be of sufficient size for the required number of wires under paving. 9. Pipe sizes shall conform to those shown on the drawings. No substitutions of smatter pipe sizes shall be permitted, but substitutions of larger sizes may be approved. All damaged and rejected pipe shall be removed from the site at the time of said rejection. 10. All sprinkler heads shall be set perpendicular to finish grade unless otherwise specified. Install all heads with triple swing joints as per detail. All heads adjacent to parking lots, walks, roads, or other paved areas shalt be Installed with pop-up bodies. 11. The Contractor shall flush and adjust all sprinkler heads, drip tubing, and valves for optimum coverage with minimal misting and/or over spray onto walks, streets, walls, etc. Substitution of nozzle pattern or radius as required to achieve optimum coverage Is responsibility of contractor. 12. Where drawing dimensions do not match field dimensions, contractor is responsible for adding sprinkler heads, relocating sprinkler heads, adjusting nozzle sizes etc. in order to maintain head to head coverage. 13. All irrigation equipment not otherwise detailed or specified shall be Installed as per manufacturer's recommendations and specifications. 14. Drip tubing shall be installed in parallel rows (wherever possible) 18' apart and 4' below the finish grade, with emitter spacing of adjacent rows staggered. Tubing shall be firmly staked in place with U -staples at 5' on center (21on center around tight curves). In steeply sloped areas, install tubing rows perpendicular to the direction of the slope. Install flush valves at the ends of drip tubing runs, and air/vacuum relief valves at the circuit's major high points (as indicated on plans). Install flush valves and air relief valves in 6' valve boxes. Drip Irrigation tubing shall be connected to Schedule 40 PVC supply and exhaust manifolds where indicated on the plans. 15. All remote control valves, gate valves, flush valves, and pressure relief valves shall be Installed in suitable valve boxes as shown in details, complete with locking covers. All shall be Carson, Amtec, or approved equal, and shall be marked 'G.V.' for gate valves, 'R.C.V.' for remote control valves, etc. Provide expansion colts at each wire connection In valve box as per details. 16. Install all backflow prevention devices and all piping between the point of connection and the backflow preventer as per local codes. Final location of the backflow preventer and automatic controller shall be approved by the Owner. 17. 120 VAC electrical power source at controller location shalt be provided by others. The Contractor shalt make the final connection from the electrical source to the controller. 1 18.4 '-RUN 2 EXTRA WIRES `L 3 21.8 5 19.5 17.8 7 TO END OF MAINLINE. 1 " 1 1 STUB OUT IN #1 VALVE BOX. 1 19 WIRES TO BE DIFFERENT COLOR 4_ 21.8 6 17.8 1" THAN PILOT WIRES OR COMMON WIRE 1" 1" Q 0 ry LOCATE BACKFL DEVICE IN PLANT AF 2" METER VER LOCATION IN FI ------------- SAN SEVAINE ATE VALVE TO BE LOCATEC OF ROMA WAYON SAN 5 , L./If I YL PRIOR TO STREET CROSSING NOTE: ALL CITY OF FONTANA SPECIFICATIONS' AND DETAILS AS NOTED IN THE ENGINEERING DIVISION LANDSCAPE DEVELOPMENT SECTION SPECIFICATION MANUAL FOR STREETSCAPES SHALL APPLY.
