<br />13. THE IRRIGATION CONTRACTOR SHALL FLUSH AND ADJUST ALL
<br />SPRINKLER HEADS FOR OPTIMUM PERFORMANCE AND TO PREVENT
<br />OVER SPRAY ONTO WALKS, ROADWAYS, AND/OR BUILDINGS AS MUCH
<br />AS POSSIBLE. THIS SHALL INCLUDE SELECTING THE BEST DEGREE
<br />OF ARC TO FIT THE EXISTING SITE CONDITIONS AND TO THROTTLE
<br />THE FLOW CONTROL AT EACH VALVE TO OBTAIN THE OPTIMUM
<br />OPERATING PRESSURE FOR EACH SYSTEM.
<br />14. ALL SPRINKLER HEADS SHALL BE SET PERPENDICULAR TO FINISH
<br />GRADE OF THE AREA TO BE IRRIGATED UNLESS OTHERWISE NOTED
<br />ON THE DRAWINGS.
<br />15. LOCATE BUBBLERS ON UP -HILL SIDE OF PLANT OR TREE.
<br />16. AT LOCATIONS WHERE LOW SPRINKLER HEAD DRAINAGE WILL CAUSE
<br />EROSION AND/OR EXCESS WATER, USE A RAIN BIRD 1800 -SAM SERIES
<br />POP-UP BODY WITH INTEGRAL CHECK VALVE AND A VALCON 5000
<br />SERIES SPRING LOADED CHECK VALVE ON SHRUB RISERS IN LIEU OF
<br />SCHEDULE 80 COUPLING.
<br />17. WHERE IT IS NECESSARY TO EXCAVATE ADJACENT TO EXISTING
<br />TREES, THE CONTRACTOR SHALL USE ALL POSSIBLE CARE TO AVOID
<br />INJURY TO TREES AND TREE ROOTS. EXCAVATION IN AREAS WHERE
<br />TWO (2) INCH AND LARGER ROOTS OCCUR SHALL BE DONE BY HAND.

<br />18. IRRIGATION CONTRACTOR TO NOTIFY ALL LOCAL JURISDICTIONS
<br />FOR INSPECTION AND TESTING OF INSTALLED BACKFLOW
<br />PREVENTION DEVICE.
<br />19. THE SPRINKLER SYSTEM DESIGN IS BASED ON THE MINIMUM
<br />OPERATING PRESSURE SHOWN ON THE IRRIGATION DRAWINGS. THE
<br />IRRIGATION CONTRACTOR SHALL VERIFY WATER PRESSURE PRIOR
<br />TO CONSTRUCTION. REPORT ANY DIFFERENCE BETWEEN THE
<br />WATER PRESSURE INDICATED ON THE DRAWINGS AND THE ACTUAL
<br />PRESSURE READING AT THE IRRIGATION POINT OF CONNECTION TO
<br />THE OWNER'S AUTHORIZED REPRESENTATIVE.
<br />20. IRRIGATION DEMAND: ISo GPM AT 60 PSI STATIC PRESSURE AT
<br />IRRIGATION POINT OF CONNECTION.
<br />21. THE EXISTING MAIN LINE SHOWN ON THE DRAWINGS IS
<br />DIAGRAMMATIC. CONTRACTOR TO VERIFY AND LOCATE EXISTING
<br />MAIN LINE IN FIELD. ANY DEVIATION OF EXISTING MAIN LINE
<br />LOCATION AS SHOWN ON THE DRAWINGS IS TO BE REPORTED TO
<br />ARCHITECT FOR REVIEW AND POSSIBLE REVISION.
<br />22. COLOR CODE WIRES FOR EASE OF IDENTIFICATION BY PROVIDING A
<br />DIFFERENT COLOR CONTROL WIRE FOR ADJACENT CONTROLLERS.
<br />23. PIPE THREAD SEALANT COMPOUND SHALL BE LASCO #905-305,
<br />PERMATEX 51 OR RECTOR SEAL T+2.
<br />24. THE CONTRACTOR SHALL EXERCISE CARE WHEN WORKING IN AREAS
<br />ADJACENT TO EXISTING PLANTING AND IRRIGATION TO REMAIN.
<br />EXISTING TREES, SHRUBS, LAWNS AND OTHER PLANT MATERIALS TO
<br />REMAIN SHALL BE PROTECTED AT ALL TIMES. IRRIGATION LINES
<br />SERVICING EXISTING PLANTING AREAS TO REMAIN SHALL BE CUT
<br />AND TEMPORARILY CAPPED DURING DEMOLITION AND RESTORED TO
<br />FULL OPERATION UNDER THIS CONTRACT UNLESS SPECIFICALLY
<br />NOTED ON THE PLANS AS BEING OTHERWISE. CONTRACTOR SHALL
<br />PROVIDE TEMPORARY IRRIGATION IN THESE AREAS UNTIL
<br />IRRIGATION CAN BE FULLY RESTORED. EXISTING PLANT MATERIALS
<br />SHALL BE MAINTAINED IN A HEALTHY CONDITION UNLESS
<br />OTHERWISE NOTED ON THE PLANS AS BEING REMOVED OR
<br />REPLACED. SAN JOAQUIN
