PLANTING NOTES:1.Verify bedlines and plant layout with landscape architect prior tocommencing work.2.Verify that site conditions are acceptable prior to beginning work. Do notinstall any site elements or plant material until unsatisfactory conditionsare corrected. When conditions detrimental to plant growth/constructedelements are encountered, immediately notify the owner.3.Substitutions or changes in materials and placement shall be made onlyafter written change orders are accepted by the owner.4.Install protective fencing for on site existing trees and vegetation toremain, and plant material located on adjacent property prior tocommencing work. The critical root protection area of all trees to remainhas been established as a 1' radius of protection area for every 1" ofdiameter measured at 4.5' above grade, or the tree drip line, whichever isgreater. Locate tree protection fencing as indicated on plan. Fencing isto be installed with stakes driven into the ground, not mounted on cinderblocks. Signage shall be affixed to the fencing that reads: 'No Entry,Tree Root Protection Area'. See existing tree and vegetation protectiondetail for additional information.5.All areas subject to clearing and grading that have not been covered byimpervious surface, incorporated into a drainage facility or engineered asstructural fill or slope shall, at project completion, demonstrate thefollowing:1) General Soil Requirements: The topsoil layer shall have a minimumdepth of eight inches except where tree roots limit the depth ofincorporation of amendments needed to meet the criteria. Subsoilsbelow the topsoil layer should be scarified at least 4 inches with someincorporation of the upper material to avoid stratified layers, wherefeasible. The topsoil layer shall have an organic matter content of 5%dry weight for turf areas, and 10% dry weight for planting beds (typicallyaround 20-25% compost for turf areas and 35-40% compost for plantingareas). The soil portion must be 75-80% sandy loam for turf areas, and60-65% sandy loam for planting areas. Soil pH should be 5.5-6.5 for turfareas, 5.5-7.0 for planting areas and 4.5-5.5 for areas planted withacid-tolerant or native plantings.2) Requirements for Amending Existing Soil in Place: Turf Areas - Place and rototill 1.75 inches of composted material into7.75 inches of existing soil for a total depth of 9.5 inches, and a settleddepth of 8 inches. Subsoils below this layer should be scarified at least 4inches, for a finished minimum depth of 12 inches of uncompated soil. Planting Beds - Place and rototil 3 inches of composted material into6.5 inches of existing soil for a total depth of 9.5 inches, and a settleddepth of 8 iches. Subsoils below this layer should be scarified at least 4inches, for a finished minimum depth of 12 inches of uncompated soil.Do not scarify within drip lines of existing trees to be retained.NOTES & REQUIREMENTSGENERAL NOTES:A.Plant material list submittal: within 30 calendar days after receipt of thenotice to proceed, landscape contractor shall submit a complete list ofmaterials proposed to be furnished and installed demonstratingconformance with the requirements specified.

Such proof shall besubstantiated and submitted in writing to the landscape architect orowner at least 30 days prior to start of work under this section. Theseprovisions shall not relieve contractor of the responsibility of obtainingspecified materials in advance if special growing conditions or otherarrangements must be made in order to supply specified materials.C.Plants shall be subject to inspection and approval by landscape architector owner for conformance to specifications upon delivery to the projectsite. Such approval shall not impair the subsequent right of inspectionand rejection during progress of the work. Contractor shall givelandscape architect 48 hours advance notice when plants will bedelivered to the site for inspection. Inspection of plant materials shalltake place within 24 hours of delivery to the site.D.Coordinate work with other trades as required.E.Locate all underground utilities prior to commencing work to avoiddamage to buried pipes and cables.F.Provide protection for all property, persons, work in progress, structures,utilities, walls, curbs and paved surfaces from potential damage arisingfrom this work. The contractor shall pay for any such damage at noadditional cost to the owner. Unfinished and completed work shall beprotected from erosion or trespassing, and proper safeguards shall beerected to protect the public from injury or danger.10. Plant trees, shrubs and groundcover as shown in the planting details.Roughly scarify sides of the planting pits. Install plant material at finishgrade and feather bark mulch away from base of plant. Water plant pitsthoroughly midway through backfilling and add fertilizer tablets. Balledand burlapped material that cannot be installed immediately shall beheeled in, mulched and watered regularly to keep root balls moist.11.Provide landscape maintenance immediately after planting and continueuntil final acceptance. Work shall include watering, spraying, fertilizing,pruning, resetting of plants, restoring eroded areas, adjustments tostaking and removal of weeds/debris as required for healthy plantgrowth.12.Inspection and acceptance: the owner will make an inspection forsubstantial completion of the work upon request by the contractor.13.Replacement of plantings: remove any plant from site that is either dead,or in unsatisfactory condition as determined by the owner or landscapearchitect. Replace with a new planting of equal size and species as soonas conditions permit within the normal planting season. All replacementplantings are then to be under re-instated guarantee period as specified.Identify those replacements and take whatever measures necessary toprevent similar demise of additional plant material.14.Provide root barrier in a surround or linear pattern for tree plantings whentrunk is located within four (4) linear feet of any paved surface. Deeprootuniversal barrier #UB18-2 (or approved equal). Install per manufacturer'srecommendations.Warranty:The warranty shall include replacing and planting the same size andspecies of plant material, as shown on the landscape plan and that hasbeen designated, by the landscape architect, to be replaced. Except forloss due to excessively severe climatological conditions (20 yearweather charts), installed plant materials are required to be guaranteeduntil the end of one growing season against defects and unsatisfactorygrowth, except for cases of neglect or abuse by the owners or others. Allplants replaced shall be re-instated under these plant guarantyconditions.6. Plants shall be pit planted with a 50/50 prepared mix of native soil and topsoil mix. See planting details for depth and staking requirements.7.Fertilize all installed plants during backfill operations with organicfertilizer as recommended by manufacturer.8.Mulch all planted areas with a minimum 2 inch (2") depth of medium finebark mulch.

Entire surface should be disturbed by scarification. Do not scarify within drip lines of existing trees to be retained. Place 4 inches of imported topsoil mix on surface and till into 2 inches of soil. Place second lift of 4 inches topsoil mix on surface. 4) Requirements for Reapplying Stockpiled Topsoil: Turf Areas - Reapply stockpiled soil and rototill in 1.75 inches ofcomposted material for a combined minimum depth of 8 inches of soiland compost.Planting Beds - Reapply stockpiled soil and rototil in 3 inches ofcomposted material for a combined mimimum depth of 8 inches of soiland compost. 5) Within Stormwater Systems - On-site soil mixing or placement shall not be performed if soil is saturated or frozen. Total amended soil depth shall be a minimum of 18 inches. Mix all soil amendments uniformally throughout the rain garden soil section. Amended soil shall be placed in horizontal layers in no greater than 12" lifts. Allow soils to compact and settle naturally. Areas can be watered after each lift is placed to speed settling, but should not be wetted to saturation. Until the upstream catchment area is thoroughly stabilized, flow diversion and erosion control measures must be installed to protect the bioretention area from sedimentation. 6) Rake beds to smooth, clean and remove all rocks, roots and debris over 1 inch in diameter. Water or roll turf areas to compact soil to 85 percent of maximum. Finish grade shall be at least 3 inches below adjacent hard surfaces for planting areas to allow for application of mulch. Finished grade for turf areas shall be at least 2 inches below adjacent hard surfaces. All planting areas must be mulched with 2 inches of organic material.SPACING, CONDITION &15' O.C., B&B BRANCHED @ 6'HEIGHT (STREET TREE QUALITY)DECIDUOUS TREESCOMMON NAMESIZEREMARKSSYMBOLTYPE IV PARKING LOT LANDSCAPE B&B, NURSERY GROWNQUERCUS ROBUR 'FASTIGIATA' / SKYROCKET OAKCARPINUS BETULUS 'FRANS FONTAINE' / FRANS FONTAINE HORNBEAM1 1/2" CAL.SHRUBS & GROUNDCOVERARCTOSTAPHYLOS UVA-URSI / KINNIKINNICKBERBERIS THUNBERGII 'ROSE GLOW' / ROSE GLOW BARBERRYCEANOTHUS GLORIOSUS 'PT.
