<br />IRRIGATION SHEET NOTES
<br />1. THE IRRIGATION SYSTEM DESIGN IS DIAGRAMMATIC. DUE TO THE
<br />SCALE OF THE DRAWING, ONLY THE MAINLINE PIPING IS SIZED. WHERE
<br />PIPING, VALVES, QUICK COUPLERS, ETC. ARE SHOWN OUTSIDE OF
<br />THE PLANTING AREAS, THE INTENT SHALL BE FOR THE PIPING,
<br />VALVES, ETC. TO BE INSTALLED WITHIN THE PLANTERS.
<br />2. THE CONTRACTOR SHALL BE RESPONSIBLE FOR VERIFYING ALL
<br />ACTUAL SITE CONDITIONS AND FOR MAKING PRESSURE AND GPM
<br />AVAILABLE CHECKS AT POINT OF CONNECTION. THE SYSTEM IS
<br />DESIGNED FOR 40 TO 48 GPM PER IRRIGATION VALVE. SHOULD
<br />THERE BE A DISCREPANCY, THE CONTRACTOR SHALL ADJUST THE
<br />PIPE SIZES TO RENDER THE PROPER PSI AT THE SPRINKLERS. IN NO
<br />CASE SHALL THE VELOCITY EXCEED 5.0 ON THE MAINLINE.
<br />3. LATERAL LINE (NON -PRESSURE) SIZING GUIDELINES SHALL BE AS
<br />FOLLOWS: 3/4" O.D. - 0 TO 10 GPM, 1" O.D. - 11 TO 15 GPM; 1-1/4"
<br />O.D. - 16 TO 25 GPM; 1-1/2" O.D. - 26 TO 40 GPM; 2" O.D. - 41 TO 65
<br />GPM. REFER TO THE IRRIGATION EQUIPMENT SCHEDULE, THIS SHEET,
<br />FOR SPRINKLER SPECIFICATION ON GPM.
<br />4. IRRIGATION PIPE DEPTHS: MAINLINE AND LATERAL LINES UNDER
<br />SERVICE DRIVES -30 INCHES OF COVER OVER PIPES; MAINLINE AND
<br />LATERAL LINES UNDER ALL OTHER PAVED AREAS - 24 INCHES OF
<br />COVER OVER PIPES. ALL PIPES UNDER PAVING SHALL BE BEDDED IN
<br />6 INCHES OF CLEAN SAND AROUND PIPES. IN PLANTING AREAS
<br />MAINLINES ARE TO HAVE 18 INCHES, AND LATERAL LINES 12 INCHES
<br />OF COVER OVER PIPES.
<br />5. STUB OUT CONNECTION POINTS ARE SHOWN AS 2". IMMEDIATELY
<br />INCREASE SIZE OF PIPE AND INSTALL A 2-1/2" GATE VALVE IN VALVE
<br />BOX.
<br />6. ALL LOW VOLTAGE CONTROL WIRE UNDER PAVED AREAS SHALL BE
<br />SLEEVED. CONTROL WIRES SHALL FOLLOW THE MAINLINE ROUTING
<br />TAPED AND BUNDLED EVERY 20 FEET.
<br />7. ALL WIRE CONNECTIONS SHALL BE MADE AT REMOTE CONTROL
<br />VALVES ONLY, WITH RAINBIRD #ST-03/PT-S5 SNAP-TITE
<br />CONNECTORS. PROVIDE A 2 FOOT COIL OF WIRE FOR EACH
<br />CONNECTION. TAPE WIRE BUNDLES EVERY 20 FEET.
<br />8. ALL GATE VALVES AND REMOTE CONTROL VALVES SHALL BE
<br />HOUSED IN VALVE BOXES AS SHOWN IN THE DETAILS.
<br />9. IRRIGATION CONTROLLERS SHALL BE WALL MOUNTED BACK TO BACK
<br />IN TWO (2) IRRIGATION ENCLOSURE HOUSINGS WITH SUB -ASSEMBLY
<br />PANELS. ELECTRICAL SUPPLY PROVIDED TO THE LOCATION BY
<br />ELECTRICAL CONTRACTOR.
<br />10. THE IRRIGATION SPRINKLER LOCATIONS SHALL BE COORDINATED
<br />WITH PLANT MATERIAL PLACEMENT.
<br />11. THE CONTRACTOR SHALL BE RESPONSIBLE FOR COORDINATING HIS
<br />WORK WITH OTHER TRADES.
<br />12. REFER TO THE SPECIFICATIONS
<br />13. MAINTENANCE PERIOD 60 DAYS.
