IRRIGATION NOTES AND SPECIFICATIONS
1.IRRIGATION SYSTEM WILL BE UTIILIZING WELL WATER. SEE L600 FOR PROPOSED WELL LOCATION.
2.ALL VALVE BOXES TO BE STANDARD SIZE OR LARGER.
3.IRRIGATION MAIN LINE TO BE 1.5" SCH 40 PVC PIPE OR 150 PSI POLY PIPE.
4.ALL TREES TO BE IRRIGATED THROUGH DEDICATED EMITTERS. EMITTERS TO BE EVENLY
DISTRIBUTED AROUND BASE OF TREE WITH FOUR (4) EVENLY SPACED 1 GPH EMITTERS.
5.TREES AND SHRUBS PLACED WITHIN PLANTING BEDS MAY UTILIZE DRIP IRRIGATION. DRIP IRRIGATION
TO BE ADJUSTED PER REQUIREMENTS OF EACH INDIVIDUAL PLANT.
6.ALL SHRUBS OUTSIDE OF DEDICATED PLANTING BEDS TO HAVE DEDICATED EMITTERS. EMITTERS TO
BE EVENLY DISTRIBUTED AROUND BASE OF SHRUB WITH TWO (2) EVENLY SPACED 1 GPH EMITTERS.
7.ALL MIXED SHRUB AND PERENNIAL PLANTINGS TO BE IRRIGATED WITH DEDICATED DRIP TUBING. DRIP
EMITTERS TO BE ADJUSTED PER REQUIREMENTS OF EACH INDIVIDUAL PLANT.
RECOMMENDED EMITTERS PER PLANT TYPE:
PERENNIALS- (1) 0.5 GPH EMITTER
SHRUBS- (2) 1.0 GPH EMITTERS
TREES- (4) 1.0 GPH EMITTERS
***TREES UTILIZING DRIP IN PLANTING BEDS MAY NEED ADDITIONAL EMITTERS TO MEET
WEEKLY WATERING REQUIREMENTS.
8.LAWN AND SEED AREAS TO BE IRRIGATED WITH SPRAY OR ROTOR OVERHEAD IRRIGATION AS
INDICATED ON PLAN.
9.DECIDUOUS TREES IN NATIVE TO HAVE TREE GUARD TO PROTECT FROM DAMAGE THAT MAY OCCUR
FROM IRRIGATION SPRAY.
10.ALL HEADS MUST ACHIEVE HEAD-TO-HEAD COVERAGE FOR SOD AREAS.
11.SYSTEM SHALL UTILIZE WEATHER / MOISTURE MONITOR CONTRACTOR TO VERIFY LOCATION IN FIELD.
12.BACKFLOW ASSEMBLY AND BLOWOUT ASSEMBLY SHALL BE LOCATED IN MECHANICAL ROOM OR
APPROVED EXTERNAL GRADEBOX. IT IS THE RESPONSIBILITY OF THE LANDSCAPE CONTRACTOR TO
COORDINATE INSTALLATION PER LOCAL CODES AND ORDINANCES AS WELL AS WITH ARCHITECTURE
AND ALL OTHER TRADES.
13.POWER SOURCE FOR IRRIGATION CONTROLLER TO BE COORDINATED WITH ELECTRICAL ENGINEER,
ELECTRICAL CONTRACTOR AND LANDSCAPE CONTRACTOR, VERIFY LOCATION IN FIELD
14.DO NOT INSTALL IRRIGATION SYSTEM WHEN OBVIOUS OBSTRUCTIONS OR GRADE CHANGES ARE
PRESENT.
15.ALL INFORMATION TO BE FIELD-VERIFIED BY CONTRACTOR PRIOR TO INSTALLATION.
16.THE CONTRACTOR SHALL MAINTAIN AN ACCURATE & CURRENT 'AS-BUILT' IRRIGATION PLAN ON SITE
AT ALL TIMES.
17.SYSTEM DESIGNED TO FALL WITHIN OPERATING PRESSURE OF 50 PSI AND 35 GPM. IF NOT WITHIN
LIMITS, CONTRACTOR MUST CONTACT LANDSCAPE ARCHITECT.
18.ALL MAIN LINE, LATERAL LINES, AND SPRINKLERS TO BE BURIED TO PROPER DEPTHS, ANY LINE
LAYING ON THE SURFACE UPON PROJECT COMPLETION OF PROJECT WILL NOT BE ACCEPTABLE. DRIP
LINE TO BE STAKED TO SURFACE AND COVERED WITH MULCH.(UNDER WEED MAT WHEN APPLICABLE)
-MAIN BURY DEPTH = MIN. 18" BELOW FINISH GRADE
-LATERAL LINE BURY DEPTH = MIN.12 " BELOW FINISH GRADE
--ALL SPRINKLERS TO BE SET IN GROUND AND FLUSH WITH FINISHED SURFACE, COMPACT FILL
AROUND SPRINKLER HEAD TO ENSURE PROPER BURIAL AND NO MOVEMENT.
19.ALL SPRAY AND ROTOR HEADS WITHIN SOD LAWN AREAS TO BE HAVE MSMT NOZZLES THAT PROVIDE
A PRECIPITATION RATE OF 0.4-0.8"/HR.
20.ALL SPRAY AND ROTOR HEADS TO BE PROPERLY INSTALLED AND ADJUSTED IN FIELD TO MINIMIZE
OVERTHROW ONTO PAVEMENT.
