DURING CONSTRUCTION. REPAIR ANY DAMAGE TO UTILITIES, BUILDING,
PAVING OR OTHER WORK AT YOUR EXPENSE.
LANDSCAPE AREA GRADING
FINISH SUBGRADE AND OBTAIN APPROVAL OF LANDSCAPE ARCHITECT AND
INSPECTOR PRIOR TO PLACING ANY TOPSOIL. FINISH SUBGRADE SHALL BE
SMOOTH AND CONFORM TO THE FINAL FINISH GRADE AFTER TOPSOIL
PLACEMENT. ALLOW FOR ADDED TOPSOIL AND MULCH IN INDIVIDUAL
PLANTINGS AS SPECIFIED. COMPACT ALL LANDSCAPE SUBGRADE TO 90% OF
OPTIMUM DENSITY PER ASTM D 1557.
FINISH GRADE OF PLANTING WHERE ABUTTING PAVING OR CURBS SHALL BE
1/2 INCH BELOW TOP OF PAVING. SLOPE ALL PLANTING AREAS AT A
MINIMUM OF 1/4 INCH PER FOOT TO PROVIDE POSITIVE DRAINAGE AWAY
FROM PLANTINGS.
EXERCISE EXTREME CAUTION WITHIN EXISTING TREE DRIP LINES TO NOT
DAMAGE TREE ROOTS. SHOULD EXISTING TREE ROOTS INTERFERE WITH
IRRIGATION SYSTEM INSTALLATION CUT ROOTS AND TREAT CUTS. IDEALLY
LIMIT IRRIGATION TRENCHING OPERATIONS WITHIN TREE DRIP LINES.
EXISTING BRUSH AND VEGETATION REMOVAL
COMPLETELY CLEAR AND GRUB EXISTING VEGETATION IN ALL LANDSCAPE
AREA PLANTING BEDS AND BARK MULCHED AREAS EXCEPT WHERE INDICATED
ON THE PLANS AS TREES AND SHRUBS REMAINING.
SOIL CONDITIONS
VERIFY EXISTING SOIL CONDITIONS FOR CONTAMINANTS THAT MAY HAVE BEEN
DISCARDED BY OTHER TRADES, SUCH AS THINNER AND PLASTER. REPORT
FINDINGS IMMEDIATELY TO LANDSCAPE ARCHITECT.
NOTIFY THE LANDSCAPE ARCHITECT OF ADVERSE SOIL DRAINAGE CONDITIONS
WHICH MAY POTENTIALLY AFFECT PLANT GROWTH (E.G. SATURATED SOIL,
CLAY, HARDPAN, HIGH GRAVEL OR ROCK CONTENT, CONCRETE, ETC.)
PLANTING BED PREPARATION AND TOPSOILING
(EXCEED MINIMUM REQUIREMENTS OF CITY OF RENTON SWDM C2.23 SOIL
AMENDMENT. SEE DETAIL 200/C2.3C. CONFORM TO APPROVED SOIL
MANAGEMENT PLAN AND AS DEFINED BELOW)
OBTAIN APPROVAL OF SUBGRADE PREPARATION PRIOR TO INSTALLING
IMPORTED TOPSOIL AND COMPOSTED MULCHES.
SUBSOILS SHALL BE SCARIFIED TO 12" DEPTH. ADD 3" DEPTH OF COMPOSTED
MULCH TO SURFACE AND ROTOTILL TO DEPTH OF 6". CITY SITE INSPECTOR
SHALL TEST SUBGRADE VIA STAINLESS STEEL ROD PENETRATION TO 12"
DEPTH PRIOR TO ADDITION OF 3" COMPOST TO SUBGRADE.
INSTALL 8 INCH MINIMUM DEPTH TOPSOIL OVER THE PREPARED SUBGRADE.
TOPSOIL SHALL BE 30% PER VOLUME COMPOST AND 70% PER VOLUME
SANDY LOAM THROUGH 7/16" SCREEN. PREAPPROVED MULCH SHALL BE
CEDARGROVE COMPOST. PH SHALL BE FROM 6.0 TO 8.0. COMPOST
COMPONENT SHALL BE CEDARGROVE COMPOST.
SUBMIT 1 POUND SAMPLE AND SOIL ANALYSIS FROM SOIL MANUFACTURER
FOR APPROVAL BY LANDSCAPE ARCHITECT. MANUFACTURED TOPSOIL SHALL
PROVIDE ALL COMPONENTS NECESSARY FOR OPTIMUM PLANT GROWTH.
COMPOST MUST HAVE AN ORGANIC MATTER CONTENT OF 40% TO 65%, AND
A CARBON TO NITROGEN RATIO BELOW 25:1.
PRIOR TO PLANTING, ONE 12" DEEP TEST HOLE PER PLANTING BED SHALL BE
DUG USING ONLY A GARDEN SPADE DRIVEN SOLELY BY INSPECTOR'S WEIGHT.
AFTER PLANTINGS AND CLEANING PLANTING GRADE IN PLANTING BEDS,
INSTALL 3 INCH MINIMUM OF CEDARGROVE COMPOST MULCH OVER THE
TOPSOIL. SEE DETAIL.
FERTILIZER
PLANTS: OSMOCOTE 18-6-12 FOR TOP DRESSING SHRUB AND GROUNDCOVER
AREAS AT A RATE OF 20 LBS. PER 1,000 SQUARE FEET PRIOR TO ADDING
MULCH TO FINISH TOPSOIL GRADE. INSTALL AGRIFORM 20-10-15 PLANTING
TABLETS FOR PLANTING PITS AS SHOWN IN PLANTING DETAILS.
PLANTING
AFTER PLACEMENT OF TOPSOIL, STAKE TREE LOCATIONS FOR ACCEPTANCE
BY THE LANDSCAPE ARCHITECT. MAKE REQUIRED FIELD ADJUSTMENTS AS
DIRECTED. AVOID OBSTRUCTIONS. LARGE BLOCKS OF PLANTING MAY BE
STAKED OUT BY BOUNDARY RATHER THAN INDIVIDUAL PLANTS. INSTALL
PLANTINGS BETWEEN OCTOBER 15TH AND MARCH 15TH.
IRRIGATION
ALL SHRUBS AND GROUNDCOVER LANDSCAPE AREAS SHALL BE IRRIGATED
VIA CONTRACTOR DESIGN BUILD/BID AUTOMATIC CONTROLLED SYSTEM.
PROVIDE COMPLETE ACCURATE AS -BUILT RECORD DRAWINGS AT 1"=20'
SCALE.
QUALITY ASSURANCE
ALL PLANT MATERIAL TO BE IN HEALTHY THRIVING CONDITION. PROTECT ALL
PLANT MATERIAL FROM HARM. HEAL -IN AND WATER ALL ROOTBALLS IF NOT
PLANTED THE SAME DAY AS DELIVERY. REMOVE UNSATISFACTORY
MATERIALS FROM SITE. PLANT DURING PERIODS NORMAL FOR OPTIMAL
GROWTH, AS DETERMINED BY SEASON, WEATHER CONDITIONS AND ACCEPTED
PRACTICE.
WARRANTY OF PLANTINGS
ACCEPTANCE OF LANDSCAPE IMPROVEMENTS SHALL OCCUR AT OWNER'S
PROVISIONAL ACCEPTANCE OF THE COMPLETED PROJECT. WARRANTY PERIOD
FOR ALL PLANTING SHALL BE ONE YEAR FROM DATE OF PROVISIONAL
ACCEPTANCE OF THE PROJECT. IF REPLACEMENT OF PLANTINGS ARE
REQUIRED DURING THE WARRANTY PERIOD, RESTORE ADJACENT PLANTING
AREA TO ORIGINAL CONSTRUCTED CONDITION. REPLACEMENT PLANTS SHALL
BE IN LIKE SIZE AND KIND AS ORIGINALLY PLANTED.
