NOTE: PLANT QUANTITIES LISTED IN SCHEDULE ARE FOR REFERENCE ONLY.
CONTRACTOR TO VERIFY QUANTITIES REFLECTED ON PLANS PRIOR TO BIDDING
PLANTING NOTES:
1.Verify bedlines and plant layout with landscape architect prior to
commencing work.
2.Verify that site conditions are acceptable prior to beginning work. Do not
install any site elements or plant material until unsatisfactory conditions
are corrected. When conditions detrimental to plant growth/constructed
elements are encountered, immediately notify the owner.
3.Substitutions or changes in materials and placement shall be made only
after written change orders are accepted by the owner.
4.Install protective fencing for on site existing trees and vegetation to
remain, and plant material located on adjacent property prior to
commencing work. The critical root protection area of all trees to remain
has been established as a 1' radius of protection area for every 1" of
diameter measured at 4.5' above grade, or the tree drip line, whichever is
greater. Locate tree protection fencing as indicated on plan. Fencing is
to be installed with stakes driven into the ground, not mounted on cinder
blocks. Signage shall be affixed to the fencing that reads: 'No Entry,
Tree Root Protection Area'. See existing tree and vegetation protection
detail for additional information.
5.All areas subject to clearing and grading that have not been covered by
impervious surface, incorporated into a drainage facility or engineered as
structural fill or slope shall, at project completion, demonstrate the
following:
1) General Soil Requirements: The topsoil layer shall have a minimum
depth of eight inches except where tree roots limit the depth of
incorporation of amendments needed to meet the criteria. Subsoils
below the topsoil layer should be scarified at least 4 inches with some
incorporation of the upper material to avoid stratified layers, where
feasible. The topsoil layer shall have an organic matter content of 5%
dry weight for turf areas, and 10% dry weight for planting beds (typically
around 20-25% compost for turf areas and 35-40% compost for planting
areas). The soil portion must be 75-80% sandy loam for turf areas, and
60-65% sandy loam for planting areas. Soil pH should be 5.5-6.5 for turf
areas, 5.5-7.0 for planting areas and 4.5-5.5 for areas planted with
acid-tolerant or native plantings.
2) Requirements for Amending Existing Soil in Place:
Turf Areas - Place and rototill 1.75 inches of composted material into
7.75 inches of existing soil for a total depth of 9.5 inches, and a settled
depth of 8 inches. Subsoils below this layer should be scarified at least 4
inches, for a finished minimum depth of 12 inches of uncompated soil.
Planting Beds - Place and rototil 3 inches of composted material into
6.5 inches of existing soil for a total depth of 9.5 inches, and a settled
depth of 8 iches. Subsoils below this layer should be scarified at least 4
inches, for a finished minimum depth of 12 inches of uncompated soil.
Do not scarify within drip lines of existing trees to be retained.
NOTES & REQUIREMENTS
GENERAL NOTES:
A.Plant material list submittal: within 30 calendar days after receipt of the
notice to proceed, landscape contractor shall submit a complete list of
materials proposed to be furnished and installed demonstrating
conformance with the requirements specified. Include the name,
addresses and telephone numbers of all plant material suppliers and
growers.
1.A.Documentation shall also include suppliers name, contact person,
address, telephone number, botanical and common name, plant
size and size of container or ball.
1.B.Contractor shall provide a signed statement from the plant suppliers
who have furnished the plant materials identifying the plant materials
being supplied by botanical and common names, plant size and
stating that all of the plants supplied by them are in healthy growing
conditions meeting the American Standard for Nursery Stock (ANSI
Z60.1).
1.C.Submit a project installation schedule, coordinated with the proposed
soil amending and planting schedule to the landscape architect or
owner for approval at least 30 calendar days prior to start of work
under this section.
B.Substitutions of plant materials will not be permitted unless authorized in
writing by the landscape architect or owner. If proof is submitted that any
plant specified is not obtainable, a proposal will be considered for use of
the nearest equivalent size and or variety. Such proof shall be
substantiated and submitted in writing to the landscape architect or
owner at least 30 days prior to start of work under this section. These
provisions shall not relieve contractor of the responsibility of obtaining
specified materials in advance if special growing conditions or other
arrangements must be made in order to supply specified materials.
C.Plants shall be subject to inspection and approval by landscape architect
or owner for conformance to specifications upon delivery to the project
site. Such approval shall not impair the subsequent right of inspection
and rejection during progress of the work. Contractor shall give
landscape architect 48 hours advance notice when plants will be
delivered to the site for inspection. Inspection of plant materials shall
take 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 avoid
damage 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 arising
from this work. The contractor shall pay for any such damage at no
additional cost to the owner. Unfinished and completed work shall be
protected from erosion or trespassing, and proper safeguards shall be
erected 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 finish
grade and feather bark mulch away from base of plant. Water plant pits
thoroughly midway through backfilling and add fertilizer tablets. Balled
and burlapped material that cannot be installed immediately shall be
heeled in, mulched and watered regularly to keep root balls moist.
11.Provide landscape maintenance immediately after planting and continue
until final acceptance. Work shall include watering, spraying, fertilizing,
pruning, resetting of plants, restoring eroded areas, adjustments to
staking and removal of weeds/debris as required for healthy plant
growth.
12.Inspection and acceptance: the owner will make an inspection for
substantial 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 landscape
architect. Replace with a new planting of equal size and species as soon
as conditions permit within the normal planting season. All replacement
plantings are then to be under re-instated guarantee period as specified.
Identify those replacements and take whatever measures necessary to
prevent similar demise of additional plant material.
14.Provide root barrier in a surround or linear pattern for tree plantings when
trunk is located within five (5) linear feet of any paved surface. Deeproot
universal barrier #UB18-2 (or approved equal). Install per manufacturer's
recommendations.
Warranty:
The warranty shall include replacing and planting the same size and
species of plant material, as shown on the landscape plan and that has
been designated, by the landscape architect, to be replaced. Except for
loss due to excessively severe climatological conditions (20 year
weather charts), installed plant materials are required to be guaranteed
until the end of one growing season against defects and unsatisfactory
growth, except for cases of neglect or abuse by the owners or others. All
plants replaced shall be re-instated under these plant guaranty
conditions.
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 organic
fertilizer as recommended by manufacturer.
8.Mulch all planted areas with a minimum 2 inch (2") depth of medium fine
bark mulch. Finish grade of mulch shall be one inch (1") below top of
adjacent hard surface.
9.All plant material to be nursery grown stock and arrive on-site in a
healthy, vigorous, well branched, disease and insect free condition.
3) Requirements for Applying Imported Topsoil:
Turf Areas and Planting Areas - Scarify or till subgrade in two
directions to 6 inches depth. 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 of
composted material for a combined minimum depth of 8 inches of soil
and compost.
Planting Beds - Reapply stockpiled soil and rototil in 3 inches of
composted material for a combined mimimum depth of 8 inches of soil
and 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
