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.

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.
