IT IS THE INTENT OF THIS DESIGN THAT ALL IRRIGATION EQUIPMENT BE INSTALLEDWITHIN PROPERTY LIMITS AND WITHIN LANDSCAPED AREAS. ANY EQUIPMENT SHOWNOUTSIDE OF THESE LIMITS IS SHOWN IN THAT LOCATION FOR GRAPHICAL CLARITYONLY. ALL VALVE BOXES SHALL BE INSTALLED A MINIMUM OF 2'-0" FROM EDGE OFANY PAVED SURFACES. ALL VALVE BOXES SHALL BE PLACED A MINIMUM OF 3'-0"FROM THE CENTERLINE OF ANY DRAINAGE SWALE.11. 1.4.Irrigation Construction Notes4" PVC (1)2" PVC (1)REQUIRED SLEEVE SIZE AND (QUANTITY)2.5.7.6.SLEEVED PIPE SIZE/WIRE QUANTITY11/2" - 2" PIPING 3/4" - 11/4" PIPINGDRIP IRRIGATION REFER TO IRRIGATION DETAIL SHEET FOR DRIP VALVE ASSEMBLY AND DRIPEMITTER QUANTITIES AND PLACEMENT.SLEEVING - ALL SLEEVING UNDER PAVED SURFACES SHOWN ON PLANS IS BYCONTRACTOR UNLESS OTHERWISE NOTED. SLEEVING SHALL BE INSTALLED IN THESIZES AND QUANTITIES SHOWN ON PLANS OR BASED ON THE SCHEDULE BELOW.WHERE SLEEVES ARE SHOWN, BUT NOT LABELED, FOLLOW THE SCHEDULE BELOW.ALL MAINLINE, CONTROL WIRES AND DRIP LINES CROSSING ANY PAVED OR HARDSURFACE SHALL BE INSTALLED IN SLEEVING.SYSTEM PRESSURE - HYDROSYSTEMS*KDI HAS CONTACTED THE LOCAL WATERDISTRICT THAT SERVES THIS SITE AND THEY HAVE BEEN TOLD THAT THE STATICWATER PRESSURE IN THIS AREA SHOULD BE 140 PSI. THE CONTRACTOR ISRESPONSIBLE TO FIELD VERIFY PRESSURE PRIOR TO COMMENCING ANYCONSTRUCTION AND NOTIFY HYDROSYSTEMS*KDI OF ANY VARIANCE FROM THESTATED PRESSURE. IF CONTRACTOR FAILS TO FIELD VERIFY PRESSURE AND/ORNOTIFY HYDROSYSTEMS*KDI OR ANY VARIATIONS FROM THIS PRESSURE, THEN HEASSUMES ALL CONSTRUCTION AND ENGINEERING COSTS ASSOCIATED WITH SYSTEMMODIFICATIONS REQUIRED TO ACCOMMODATE ACTUAL SITE PRESSURE. THISSYSTEM HAS BEEN DESIGNED FOR A REQUIRED STATIC PRESSURE OF 85 PSIMINIMUM.1.00" PER WEEK PEAK SEASON (TWO SEASONS)1.75" PER WEEK PEAK SEASON1.50" PER WEEK PEAK SEASON9.3.8.NATIVE SEED MIXES FESCUE TURF BLUEGRASS TURFSPARE CONTROL WIRES - CONTRACTOR SHALL EXTEND THREE SPARE WIRES (ONECOMMON AND 2 CONTROL WIRES) FROM EACH CONTROLLER TO THE END OF THEMAINLINE SERVING THAT CONTROLLER OR AS SHOWN ON THE PLANS, IN ADDITION TOTHE SPARE WIRE REQUIREMENTS LISTED IN TECHNICAL SPECIFICATIONS AND INIRRIGATION SCHEDULE. INSTALL SPARE WIRES IN 10" ROUND VALVE BOX OR WITHQUICK COUPLING VALVE. REFER TO SPECIFICATIONS FOR WIRE COLOR. SEEIRRIGATION SCHEDULE FOR ADDITIONAL INFORMATION.NOTE: IT IS THE INTENT OF THIS DESIGN THAT NATIVE AREAS WOULD ONLY BEIRRIGATED FOR ESTABLISHMENT.CONTRACTOR SHALL REPAIR OF REPLACE ANY EXISTING IRRIGATION EQUIPMENT,TURF, PLANT MATERIAL OR SITE FEATURES DAMAGED DURING NEW INSTALLATION.REPAIR OR REPLACEMENT SHALL BE DETERMINED BY OWNER OR OWNER'SREPRESENTATIVE AND PAID FOR BY THE LANDSCAPE CONTRACTOR.IRRIGATION SYSTEM OPERATION INTENT - THIS IRRIGATION SYSTEM HAS BEENDESIGNED TO IRRIGATE THE ESTABLISHED LANDSCAPE WITHIN A SIX NIGHT PER WEEK,SIX HOUR PER NIGHT WATERING WINDOW. ESTABLISHMENT WATERING WILL REQUIRE UPTO TWICE AS MUCH IRRIGATION FOR A FOUR TO SIX WEEK PERIOD. THE DESIGN ISBASED ON THE FOLLOWING PROJECTED WEEKLY APPLICATION RATES AFTERESTABLISHMENT. THESE FIGURES ARE BASED ON A 30-YEAR AVERAGE WEATHERDATA AND WILL NEED TO BE ADJUSTED DUE TO SEASONAL CHANGES AND WEATHERCONDITIONS ABOVE AND BELOW THE AVERAGE VALUES UTILIZED.POP-UP SPRAY NOZZLES - CONTRACTOR TO INSTALL PLASTIC NOZZLES ON ALL POP-UPSPRAY HEADS. INSTALL 15 SERIES NOZZLES ON ALL HEADS SPACED AT 13' TO 15'.INSTALL 12 SERIES NOZZLES ON ALL HEADS SPACED 11' TO 12'. INSTALL 10 SERIESNOZZLES ON ALL HEADS SPACED AT 9' TO 10'. INSTALL 8 SERIES NOZZLES HEADSFOR ALL HEADS SPACED LESS THAN 8'. INSTALL SIDE STRIP NOZZLES FOR ALLHEADS WITH AN "S" DESIGNATION AND RIGHT AND LEFT CORNER STRIP NOZZLES FORALL HEADS WITH AN "C" DESIGNATION. VARIABLE ARC NOZZLES SHOULD BE UTILIZEDADJACENT TO CURVILINEAR SHRUB BEDS OR FOR ANY ANGLES THAT ARE NOT ASTANDARD NOZZLE ANGLE.DRAWINGS AND BASE INFORMATION - ALL BASE AND PLANTING INFORMATION HAVEBEEN PROVIDED BY DHM DESIGN. THE CONTRACTOR IS RESPONSIBLE TO NOTIFYHYDROSYSTEMS*KDI OF ANY DISCREPANCIES BETWEEN THE UTILITY OR PLANTINGPLANS AND THE IRRIGATION PLAN. IF CONTRACTOR FAILS TO NOTIFYHYDROSYSTEMS*KDI AND MAKES CHANGES TO THE IRRIGATION SYSTEM DESIGN, HEASSUMES ALL COSTS AND LIABILITIES ASSOCIATED WITH THOSE FIELD CHANGES.REFER TO SPECIFICATIONS FOR ADDITIONAL PROJECT REQUIREMENTS.10.CONTRACTOR SHALL FINE TUNE/ADJUST THE IRRIGATION SYSTEM TO REDUCE/AVOIDOVERSPRAY ONTO HARD SURFACES BY ADJUSTING NOZZLE DIRECTION AND NOZZLERADIUS.2" PVC (1)1- 25 CONTROL WIRES CONTRACTOR SHALL REFER TO PLANTING PLAN FOR EXACT PLANT LOCATIONS ANDQUANTITIES. PLANTS SHOWN ON IRRIGATION PLANS ARE APPROXIMATE. THEPLACEMENT OF ALL IRRIGATION COMPONENTS SHALL BE COORDINATED WITH THELOCATION OF THE PLANTS. IF IRRIGATION THAT IS INSTALLED CONFLICTS WITH ORBLOCKS THE PLACEMENT OF LANDSCAPE PLANTS OR OTHER FEATURES, SUCH ASEDGER, THE CONTRACTOR SHALL, AT HIS OWN EXPENSE, RELOCATE THE IRRIGATIONCOMPONENTS AS REQUIRED TO ALLOW PLACEMENT OF THE PLANTS IN ACCORDANCEWITH THE PLANTING PLAN(S).REFER TO SHEET IR2 AND IR3 FOR IRRIGATION DETAILS
