IRRIGATION NOTES

1. ALL SPRINKLER HEADS SHALL BE SET PERPENDICULAR TO FINISH GRADE OF THE AREA TO BE IRRIGATED UNLESS OTHERWISE NOTED ON THE PLANS. 2. THE SPRINKLER SYSTEM DESIGN IS BASED ON THE MINIMUM STATIC PRESSURE OF 35 PSI AT THE VALVES AND THE MAXIMUM FLOW DEMAND SHOWN ON THE IRRIGATION DRAWINGS AT THE POINT OF CONNECTION. THE IRRIGATION CONTRACTOR SHALL VERIFY WATER PRESSURE PRIOR TO CONSTRUCTION OF THE IRRIGATION SYSTEM. IF THE WATER

PRESSURE SHOWN ON THE DRAWINGS DIFFERS FROM THE ACTUAL PRESSURE READING AT THE IRRIGATION POINT OF CONNECTION, THE CONTRACTOR SHALL NOTIFY THE LANDSCAPE ARCHITECT IMMEDIATELY. IN THE EVENT PRESSURE

DIFFERENCES ARE NOT REPORTED PRIOR TO THE START OF CONSTRUCTION, THE IRRIGATION CONTRACTOR SHALL ASSUME FULL RESPONSIBILITY FOR ANY REVISIONS NECESSARY. 3. THE LOCATION OF THE CONTROLLER TO BE VERIFIED BY OWNER. LANDSCAPE CONTRACTOR SHALL BE RESPONSIBLE FOR CONNECTING ALL PROPOSED STATIONS TO THE CONTROLLER. CONTROLLER TO BE CONFIGURED TO OPERATE 33 STATIONS. CONTROLLER SHALL BE HUNTER IC-600-M WITH FIVE ICM-600 EXPANSION MODULES. 4. ALL CONSTRUCTION IS TO BE PER THE LATEST EDITION OF THE UNIFORM BUILDING CODE. 5. THIS DESIGN IS DIAGRAMMATIC. ALL PIPING, VALVES, ROOT BARRIERS, ETC. SHOWN WITHIN PAVED AREAS ARE FOR DESIGN CLARIFICATION ONLY. INSTALL PIPING AND VALVES IN PLANTING AREAS WHERE POSSIBLE, AND LOCATE ELECTRIC CONTROL AND QUICK COUPLING VALVES IN GROUND COVER/SHRUB AREAS, 6" TO 12" AWAY FROM HARDSCAPE OR TURF AREA FOR EASY ACCESS. 6. THE IRRIGATION CONTRACTOR SHALL FLUSH AND ADJUST ALL SPRINKLER HEADS FOR OPTIMUM PERFORMANCE AND TO PREVENT OVER SPRAY ONTO WALKS, ROADWAYS, AND/OR BUILDINGS. THIS SHALL INCLUDE SELECTING THE

BEST DEGREE OF ARC TO FIT THE EXISTING SITE CONDITIONS AND THROTTLING THE FLOW CONTROL AT EACH VALVE TO OBTAIN THE OPTIMUM OPERATING PRESSURE FOR EACH SYSTEM. 7. IT IS THE RESPONSIBILITY OF THE IRRIGATION CONTRACTOR TO FAMILIARIZE THEMSELF WITH ALL GRADE DIFFERENCES, LOCATION OF WALLS, STRUCTURES, AND UTILITIES. THE IRRIGATION CONTRACTOR SHALL EXERCISE EXTREME CARE, AND BE RESPONSIBLE FOR ANY DAMAGE IN EXCAVATING AND WORKING NEAR UTILITIES. CONTRACTOR SHALL COORDINATE ALL WORK WITH THE GENERAL CONTRACTOR AND OTHER SUB-CONTRACTORS

FOR THE LOCATION OF UTILITIES AND THE INSTALLATION OF PIPE SLEEVES THROUGH WALLS, UNDER ROADWAYS, AND NEAR STRUCTURES. PRIOR TO CONSTRUCTION, CONTACT ALL APPLICABLE AGENCIES AND U.S.A. AT 1-800-642-2444 TO FIELD LOCATE ALL EXISTING UTILITIES. 8. FIELD ADJUSTMENTS MAY BE REQUIRED TO PROVIDE OPTIMUM OPERATING EFFICIENCY. THE CONTRACTOR

SHALL BE RESPONSIBLE FOR CONTACTING THE LANDSCAPE ARCHITECT TO REVIEW FIELD ADJUSTMENTS PRIOR TO INSTALLATION. IN THE EVENT THAT NO CONTACT IS MADE WITH THE LANDSCAPE ARCHITECT, THE CONTRACTOR SHALL BE RESPONSIBLE FOR ANY REVISIONS. 9. SLEEVE ALL IRRIGATION PIPE AND CONTROL WIRES UNDER STREETS AND CONCRETE WALKWAYS WITH THE PROPER SIZE CLASS 200 PVC PIPE TO DEPTH AS SPECIFIED.

10. FOR ADDITIONAL INFORMATION, SEE PROJECT DETAILS AND SPECIFICATIONS.

11. ALL WORK SHALL CONFORM TO ALL APPLICABLE CITY OF COTATI CONSTRUCTION STANDARDS.

12. NO GALVANIZED IRON PIPE OR FITTINGS SHALL BE ALLOWED.

13. A BALL VALVE IN A SEPARATE ROUND VALVE BOX IS TO BE INSTALLED IMMEDIATELY UPSTREAM FROM EACH REMOTE CONTROL VALVE OR GHROUP OF VALVES. VALVE SHALL BE SIZED TO MAINLINE SUPPLY AT THE RC VALVE. SEE DETAIL.

14. INSTALL 3" WIDE DETECTABLE TAPE (#3" DTP, AS MANUFACTURED BY T. CHRISTY). TAPE SHALL BE INSTALLED 6" ABOVE THE IRRIGATION MAIN.

15. INSTALL ALL LANDSCAPE DRIPLINE BENEATH MULCH. INSTALL ALL TUBING 3" BELOW GRADE, PARALLEL AT SPACING INDICATED. USE LANDSCAPE STAPLES IN ACCORDANCE WITH MANUFACTURER'S RECOMMENDATIONS TO SECURE TUBING TO GROUND.

16. A SIGNED CERTIFICATE OF COMPLETION IS REQUIRED PRIOR TO FINAL ACCEPTANCE BY THE CITY OF COTATI. IF

THE INSTALLATION OF THE LANDSCAPE DOES MEET OR SUBSTANTIALLY COMPLY WITH THE APPROVED LANDSCAPE

CONSTRUCTION DOCUMENTS, THE CERTIFICATE OF COMPLETION WILL NOT BE SIGNED OR APPROVED BY THE LANDSCAPE ARCHITECT OF RECORD.

IRRIGATION NOTES***

1. THE LANDSCAPE CONTRACTOR SHALL INSPECT THE SITE AND VERIFY CONDITIONS AND DIMENSIONS PRIOR TO CONSTRUCTION. 2. INSTALL IRRIGATION SYSTEM IN ACCORDANCE WITH ALL LOCAL CODES AND ORDINANCES. 3. SEE DETAILS AND SPECIFICATIONS FOR PROCEDURES, MATERIAL AND INSTALLATION REQUIREMENTS. 4. PRIOR TO CUTTING INTO SOIL, LOCATE ALL CABLES, CONDUITS, SEWERS, AND OTHER UTILITIES OR

THE INSTALLATION OF THE IRRIGATION SYSTEM OF THE AFOREMENTIONED ITEMS SHALL BE REPAIRED AND/OR REPLACED TO THE SATISFACTION OF THE OWNER AT THE CONTRACTOR'S OWN EXPENSE. 4. CONTRACTOR TO MINIMIZE DISTURBANCE TO EXISTING TREE ROOTS ON SITE. CUT MINOR ROOTS (LESS THAN 2"

IN DIAMETER) OF TREES INDICATED TO REMAIN IN A CLEAN AND CAREFUL MANNER WHERE SUCH ROOTS OBSTRUCT INSTALLATION OF NEW CONSTRUCTION. IF ANY ROOTS GREATER THAN 2" ARE ENCOUNTERED STOP WORK AND CONTACT THE OWNER'S REPRESENTATIVE IMMEDIATELY. 5. THE IRRIGATION DESIGN IS DIAGRAMMATIC. ALL PIPING, VALVES, ETC., SHOWN WITHIN PAVED AREAS ARE FOR DESIGN CLARIFICATION ONLY AND SHALL BE NSTALLED IN PLANTING AREAS. MAIN AND VALVES SHALL BE INSTALLED IN SHRUB/GROUND COVER AREAS ONLY. AVOID CONFLICTS WITH UTILITIES, NEW PLANTING, NEW SITE OR ARCHITECTURAL ELEMENTS. 7. ALL VALVES SHALL BE PLACED IN NDS PRO SERIES, OR EQUAL, PURPLE VALVE BOX. ALL VALVE BOXES SHALL BE LOCATED IN GROUNDCOVER AREAS WHENEVER POSSIBLE, AND SHALL BE BOLTED. 8. STATION OPERATION TIMES SHALL NOT EXCEED THE SOIL'S INFILTRATION RATE AS DETERMINED BY THE SOILS REPORT. 9. ALL LATERAL END RUNS SHALL BE 3/4" SIZE UNLESS OTHERWISE NOTED.

10. WHERE PIPE SIZES HAVE BEEN OMITTED OR THERE IS A CONFLICT, REFER TO THE LATERAL PIPE SIZING CHART FOR SIZES.

11. INSTALL ONE SPARE COMMON AND TWO SPARE CONTROL WIRES FROM EACH CONTROLLER IN A CONTINUOUS LOOP THROUGH EACH VALVE BOX CONNECTED TO THAT CONTROLLER FOR FUTURE USE.

12. CONTRACTOR SHALL COORDINATE SLEEVING FOR IRRIGATION PIPING WITH PAVING CONTRACTOR PRIOR TO PAVING INSTALLATION. IT IS THE CONTRACTOR'S RESPONSIBILITY FOR PROVIDING APPROPRIATE SLEEVING UNDER HARDSCAPE. AT EACH MAINLINE SLEEVE, PROVIDE A SEPARATE, APPROPRIATE-SIZE SLEEVE FOR CONTROL/COMMON WIRING.

13. THE LANDSCAPE CONTRACTOR SHALL COORDINATE HIS WORK WITH OTHER TRADES INVOLVED (I.E. GRADING, PLUMBING AND ELECTRICAL CONTRACTORS).

14. CONTRACTOR SHALL VERIFY ALL LOCATIONS AND FUNCTION OF EXISTING IRRIGATION EQUIPMENT AND POINTS

OF CONNECTION THAT ARE TO REMAIN OR TO CONNECT TO NEW IRRIGATION SYSTEMS, UPON NOTIFICATION OF AWARD OF CONTRACT. CONTRACTOR TO IMMEDIATELY NOTIFY LANDSCAPE ARCHITECT IF ANY DISCREPANCIES ARE FOUND BETWEEN PLANS AND EXISTING IRRIGATION CONDITIONS.

15. THE IRRIGATION SYSTEMS ARE DESIGNED TO OPERATE AT 62 PSI AT POINT OF CONNECTION TO IRRIGATION WATER SUPPLY. LANDSCAPE CONTRACTOR SHALL TEST PRESSURE AT POINT OF CONNECTION PRIOR TO INSTALLATION OF THE IRRIGATION BACKFLOW PREVENTION DEVICE, OR ANY OTHER IRRIGATION EQUIPMENT. NOTIFY LANDSCAPE ARCHITECT IMMEDIATELY IF PRESSURE IS BELOW 62 PSI OR OVER 62 PSI TO DETERMINE NEEDED PRESSURE REGULATION DEVICES. (I.E. BOOST PUMP OR REGULATING VALVE.) ***DESIGN DEVELOPMENT IRRIGATION NOTES FROM SUBMITTAL DATED 8/19/19 PREARED BY QUADRIGA LANDSCAPE ARCHITECTURE AND PLANNING, INC.
