CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
INSTRUCTIONS FOR DOCUMENTS TO BE
,. RECORDED WITH THE COUNTY RECORDER
Documents are required to be recorded prior to the final approval of
this project. This sheet explains how to ensure the document is
complete prior to returning it to the Engineering Department for
recordation and how to make payment for the recording fees.
Please ensure that the covenants/ documents are complete, with:
1) A complete and correct attached property description;
2) A plat attachment if required;
3) Signatures of all owners on the document;
4) Notary documentation (ensure use of new 2008 forms);
5) A subordination agreement if included and required.
Please submit the completed covenants with a check payable to the
San Diego County Recorder (one for each covenant, as this allows one
covenant to record even if the County Recorder finds a problem with
another covenant).
If possible, please make the check out to the SD County Recorder but
leave the amount field blank. This allows Engineering staff to fill in the
check at the County Recorder's office, eliminating the possibility of a
document being rejected if the check amount is not exactly correct.
The recording fee charged by the County Recorder can be calculated
as $16.00 for the first page and $3.00 for each additional, including
notary sheets. For encroachment covenants, a notarization of the City
Engineer's signature is required, so the check amount must include the
$3.00 fee for that page as well.
No recording fee is necessary for covenants recorded "for the benefit
of the City ".
Please contact the Engineering Department at 760 - 633 -2770 if you
have any questions.

excavations are acceptable for their intended use.
2. The contractor shall properly grade all excavated surfaces to
provide positive drainage and to prevent ponding of water.
He /she shall control surface water and avoid damage to adjoining
properties or to finished work on the site and shall take remedial
measures to prevent erosion of freshly graded areas until such
time as permanent drainage and erosion control measures have
been installed.
3. All areas to be filled shall be prepared to be filled and fill shall be
placed in accordance with standard specifications. All vegetable
matter and objectionable material shall be removed by the
contractor from the surface upon which the fill is to be placed.
Loose fill and alluvial soils shall be removed to suitable firm
natural ground. The exposed soils shall be scarified to a depth of
6" and then compacted to a minimum of 90 percent. It shall be
the contractor's responsibility to place, spread, water, and
compact the fill in strict accordance with specifications.
4. Cut and fill slopes shall be cut and trimmed to finish grade to
produce smooth surfaces and uniform cross sections. The slopes
of excavations and embankments shall be shaped, planted and
trimmed as directed by the engineer of work and left in a neat
and orderly condition. All stones, roots, and other waste matter
exposed or excavation or embankment slopes which may become
loosened shall be removed and disposed. The toe and top of all

City of Encinitas stormwater pollution control
requirements. TheseBMP notes shall be availableto
everyone working on site. Th a property own er(s) and the
prime contractor mustinform subcontractors about
stormwater requirements and their own responsibilities.
Waste Management
• Contractor shall be responsible for properly disposing of
allwaste and unused construction materials. Dumping of
unused or waste products on the ground, where water can
carry them into the conveyance system is strictly
prohibited.
No seepage from dumpsters sh all be discharged into
stormwater. Berms /dikes shall be placed around
dumpsters
to divert the natural storm runoff. Dumpsters shall be
checked frequently for leaks. Dum pster lids shall remain
closed at all times. Dumpsters without lids shall be placed
within structures with impervious roofing or covered with
tarps in order to avoid rain contact with any trash
material.
Many construction materials, including solvents, water -
based paints, vehicle fluids, broken asphalt and concrete,
wood, and cleared vegetation can berecycled. Non -
recyclable materials must be taken to an appropriate
landfill or disposed of as hazardous waste. For
information on disposal of hazardous material, call the
Hazardous Waste Hotline toll free at (800) 714 -1195.
For information on landfills and to order dumpsters call
EDCO at(760)436 -4151.
• Pollutants shall be kept off exposed surfaces. Place trash
cans and recycling receptacles around the site.
• Portable toilets must be in good working order and
checked frequently for leaks. Contractor shall provide
secondary containment and locate portable toilets away
from stormdrain inlets on pervious surfaces.

SWPPP PREPARATION GUIDANCE
s
As per the Construction General Permit Oder 2009 - 0009 -DWQ, the
State requires a Storm Water Pollution Prevention Plan (SWPPP) to be
prepared whenever a project proposes land disturbance exceeding one
acre. The applicant must pay a fee and file with the State Water
Resources Control Board to obtain a WDID number. A copy of the
SWPPP must be submitted to the City during the plancheck process. A
copy of the approved SWPPP must be kept on site during the grading
process. This copy needs to be continuously updated as the project
progresses and the storm water pollution control needs change.
Engineers can find a sample SWPPP prepared by the California Storm
Water Quality Association online at:
http:// www. cabmphandbooks .com /Construction.asp #SWPPP.
Applicants wanting professional SWPPP preparation may select an
Engineering firm specializing in storm water pollution control.
Engineers can contact our Stormwater Section at (760) 633 -2787 with
any questions about SWPPP preparation.

To SWPPP Checklist users:
This checklist is being provided as an aid to those unfamiliar in the preparation of a SWPPP. It
is a comprehensive list of issues a SWPPP preparer must consider during the development of the
document. Many sites, especially small construction sites, will not need to address some of the
listed items because they are not relevant to the site, the construction activities planned, or the
construction materials used. This list allows the preparer to consider the applicability of the item
to the specific circumstances of the site, and then determine to what extent the item should be
addressed in the SWPPP. The items in the checklist are derived from Sections A, B, and C of the
Construction General Permit, and the specific permit section is listed in the second column.
The use of this checklist does not guarantee compliance with the General Construction Storm
Water Permit. Additionally, using the checklist to generate a SWPPP is not a substitute for
knowledge of the permit requirements, the checklist serves as a guidance document only. A site
specific SWPPP must be combined with proper and timely installation of the BMPS, thorough
and frequent inspections, maintenance, and documentation.

CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
INTRODUCTION
The City of Encinitas is fortunate to have such a beautiful population of trees, including
magnificent individual trees, groupings of trees and native trees which give the City a unique
character. Trees are a source of shade, air conditioning and other environmental benefits, and
yield both a high quality of life and economic benefits to the community, including enhanced
property values.
The City is dedicated to the planting and protection of its urban forest which is recognized as one
of the City's greatest natural resources. Sustaining trees in Encinitas' developed environment
presents a challenge, requiring careful planning and maintenance.
The Urban Forest Management Policy is the City's primary regulatory tool to provide for orderly
protection of trees, to promote the health, safety, welfare, and quality of life for the residents of
the City, to protect property values and to avoid significant negative impacts on adjacent
properties. By assuring preservation and protection through regulations and standards of care,
these resources will remain significant contributions to the landscape, streets and parks, and
continue to help define Encinitas.
This Manual is issued by the City Manager, through the Departments of Building and Planning,
Engineering Services, Parks and Recreation and Public Works to establish specific technical
standards and specifications necessary to implement the policy. Terms defined in Section 1.00
Definitions appear italicized throughout this Manual.
APPENDIX 3.16 PAGE 3 -51
SECTION 1.00 -
For the purpose of this Manual and interpretation of regulations, the following definitions shall
apply:
Basal Flare means that portion of a tree where there is a rapid increase in diameter at the
confluence of the trunk and rootcrown.
Building Area means the area of a parcel that (1) upon which, under applicable zoning
regulations, a structure may be built without a variance or; (2) is necessary for the construction
of primary access to structures located on the parcel, where there exists no feasible means of
access which would avoid protected trees. On single - family residential parcels, the portion of the
parcel deemed to be the Building Area access shall not exceed twelve (12) feet in width or
sixteen (16) feet if required by the Fire Department.
Building Footprint means the two- dimensional configuration of a building's perimeter
boundaries measured on a horizontal plane at grade level.
Certified Arborist is an individual who has a demonstrated knowledge and competency through
obtainment of the current International Society of Arboriculture arborist certification, or who is a
member of the American Society of Consulting Arborists. A Certified Arborist can be found in
the yellow pages of the local telephone book or by contacting the Western Chapter of the ISA at
(916) 641 -2990 (www.wcisa.orQ).
City Arborist means the person(s) designated as such by the City of Encinitas.
City Tree any tree growing within the City street right -of -way, on City property or within City
easements.
Compaction means compression of the soil structure or texture as described by the latest edition
of the Standard Specifications for Public Works Construction (Greenbook). Compaction is
injurious to roots and the health of a tree.
Dead Tree means a tree that is dead or that has been damaged beyond repair or is in an advanced
state of decline (where an insufficient amount of live tissue, green leaves, limbs or branches,
exists to sustain life) and has been determined to be such by a Certified Arborist.
Diameter at Breast Height (DBH) means the diameter of the perimeter tree trunk at four and
one -half feet (or 54 inches) above natural grade level. The diameter may be calculated by using
the following formula: DBH — circumference at 4.5 -feet x 3.142 (D —C x P). To determine the
DBH of multi -trunk trees or measuring trees on slopes, consult the current Guide for Plant
Appraisal, published by the Council of Tree and Landscape Appraisers.
Discretionary Development Approval means an approval granted by the Planning and Building
Director, Planning Commission, and/or City Council for applications including but not limited to
coastal development permits, use permits, variances, subdivisions, and design reviews.
PAGE 3 -52 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
Disturbance refers to all of the various activities that may damage trees.
Dripline Area means the area from the trunk of a tree to the outermost edge of the tree canopy.
Excessive Pruning means removing in excess, one -fourth (25 percent) or greater, of the
functioning leaf, stem or root area. Pruning in excess of 25 percent is injurious to the tree and is
a prohibited act. Excessive Pruning typically results in the tree appearing as a "bonsai ", "lion's -
tailed", "lolly- popped ", or overly thinned.
A. Unbalanced Crown - Excessive Pruning also includes Removal of the leaf or stem area
predominantly on one side, Topping, or excessive tree canopy or crown raising.
Exceptions are when clearance from overhead utilities or public improvements is
required or to abate a hazardous condition or a Public Nuisance.
B. Roots - Excessive Pruning may include the cutting of any root two (2) inches or greater
in diameter and/or severing in excess of 25 percent of the roots.
Hazardous Tree an imminent hazard or threat to the safety of persons or property. If a tree
possesses a structural defect that may cause the tree or part of the tree to fall on someone or
something of value (i.e. `Target'), and the condition is determined to be imminent, the tree is
considered hazardous.
Heritage Tree is a tree designated by the process outline in Section 9.00 of this Manual that is
one of the oldest or largest of its species located in the City and has historic significance due to
an association with an historic building, site, street, person or event or it is a defining landmark
or significant outstanding feature of a neighborhood.
Iniury means a wound resulting from any activity, including but not limited to "Excessive
Pruning" cutting, Trenching, excavating, altering the grade, paving or Compaction within the
TPZ of a tree. Injury shall include bruising, scarring, tearing, or breaking of roots, bark, trunk,
branches or foliage, herbicide or poisoning, or any other action foreseeable leading to the death
or permanent damage of the tree health.
Landscape Architect means a person licensed or registered in the planning, design and
sometimes oversight of an exterior landscape or space.
Proiect Arborist means a Certified Arborist retained by a property owner or development
applicant for the purpose of overseeing on -site activity involving the welfare of the trees to be
retained or planted. The Project Arborist shall be responsible for all reports, tree preservation
plans, or inspections as required.
Protective Tree Fencing means a temporary enclosure erected around a tree to protect the
boundary of the tree protection zone (TPZ). The fence services three primary functions:
A. to keep the foliage crown, branch structure and trunk clear from direct contact and
damage by equipment, materials or Disturbances;
B. to preserve roots and soil in and non - compacted state; and
C. to identify the TPZ in which no soil Disturbance is permitted and activities are restricted.
APPENDIX 3.16 PAGE 3 -53
Public Nuisance means either an individual tree on any private property or on any street, public
property, or a type or species apt to destroy, impair or otherwise interfere with any street
improvements, sidewalks, curbs, gutters, sewers, or other public improvements, including above
and below ground utilities.
Removal means the complete tree Removal such as cutting to the ground or extraction of the
tree.
Root Buffer means a temporary layer of material to protect the soil, texture and roots. The
buffer shall consist of a base course of tree chips spread over the root area to a minimum of 6-
inch depth, capped by a base course of 3/4 —inch quarry gravel to stabilize 3/4 -inch plywood on
top.
Site Plan means a set of drawings (e.g. preliminary drawings, Site Plan, grading, demolition,
building, utilities, landscape, irrigation, tree survey, etc.) that show existing site conditions and
proposed landscape improvements, including trees to be removed, relocated and/or retained. Site
Plans shall include the following minimum information that may impact trees:
A. Surveyed tree locations, species, size (height, width, DBH). Dripline Area (including
trees located on neighboring property that overhang or within 50 feet of the project site)
and City Trees adjacent to the project site;
B. Paving, concrete, Trenching, or grade change (including the limits of over - excavation)
located within the Tree Protection Zone-,
C. Existing and proposed utility easements;
D. Surface and subsurface drainage and aeration systems to be used;
E. Walls, tree wells, retaining walls and grade change barriers, both temporary and
permanent
F. Landscaping, irrigation and lighting within dripline of trees, including all lines, valves,
etc;
Soil Fracturing means the loosening of hard or compacted soil around a tree by means of a
pneumatic soil probe (Gro -gun) that delivers sudden bursts of air to crack, loosen, or expand the
soil to improve the root growing environment.
Structural Defect means any structural weakness or deformity of a tree or its parts.
Target is a term used to include people, vehicles, structures or something subject to damage if a
tree or part of a tree fails.
Topping means the practice of cutting back large- diameter branches or truncating the main stem.
Tree Protection and Preservation Plan means a plan prepared by a Certified Arborist that
outlines measures to protect and preserve trees on a project. This plan shall include requirements
for preconstruction; treatments during demolition and/or construction; establishment of a Tree
Protection Zone, tree monitoring and inspection schedule; and provide for continued
maintenance of those trees after construction according to the requirements in this Manual
PAGE 3 -54 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
Tree Protection Zone (TPZ) means unless otherwise specified by a Project Arborist or City
Arborist, the area of temporary fenced tree enclosure. Within the TPZ, roots that are critical for
tree survival are typically found in the upper three foot soil horizon, and may extend beyond the
Dripline Area Protecting the roots in the TPZ is necessary to ensure the tree's survival. The
TPZ is a restricted activity zone where no soil Disturbance is permitted, unless otherwise
approved. TPZ must be identified for each tree and shown on all applicable improvement plans
for a development project.
Tree Report means a report submitted to the City for review that is prepared by a Certified
Arborist retained by the property owner or agent. In the case of a discretionary development
approval, a tree survey report is required to provide information about all trees on the site
including: inventory of all trees, location, species, size, condition, maintenance needs, potential
impacts of Disturbance, recommended mitigation measures, tree appraisal value, etc.
Trenching means any excavation to provide irrigation, install foundations, utility lines, services,
pipe, drainage or other improvements below grade. Trenching within the TPZ is injurious to
roots and tree health and is prohibited, unless approved. If Trenching is approved within the
TPZ, it must be in accordance with instructions and table outlines in this Manual
Verification of Tree Protection means the Project Arborist shall verify, in writing, that all pre -
construction conditions have been met (tree fencing, erosion control, pruning, etc.) and are in
place. An initial inspection of protective fencing and written verification must be submitted to
the City Arborist prior to demolition, grading and/or building permit issuance.
Vertical Mulching means angering, hydraulic or air excavation of vertical holes within a tree's
root zone to loosen and aerate the soil, typically to mitigate compacted soil. Holes are typically
penetrated 4- to 6 -feet on center, 2 -to 3 -feet deep, 2 -to 6- inches in diameter and backfilled with
either perlite, vermiculite, peat moss or a mixture thereof.
Wildland Urban Interface/Defensible Space means the geographical area where structures and
other human development meets /or intermingles with wildland or vegetative fuels.
APPENDIX 3.16 PAGE 3 -55
SECTION 2.00 - PROTECTION OF TREES DURING CONSTRUCTION
Introduction
The objective of this section is to reduce the negative affects of construction on trees to a less
than significant level.
Land development and infrastructure construction is a complex process and is even more
challenging when trees are involved.
One long -term goal of the City of Encinitas is urban forest sustainability. This describes the
maintenance of social, recreational, ecological and economic functions of trees and their benefits
over time. Stewardship of naturally occurring and planted trees is a central element in urban
forest sustainability. Concerns about tree health and structure, preservation during development
and other construction activities, species and site selection, quality of planting stock, standards of
performance, maintenance practices in our parks, and recycling are integral to a sustainable
urban forest.
Tree protection should begin before construction starts. If preservation measures are delayed or
ignored until construction begins, the trees may be destined to fail. In many cases, construction
affects to trees cannot be completely eliminated. Therefore, the City's goal is to keep Injury to
trees to a minimum and allow construction projects to proceed at the same time.
Successful tree preservation occurs when designers, construction personnel, and project
managers are committed to tree preservation. All members of the project team must be familiar
with the rudimentary aspects of tree growth and development in order to understand the
relationship between tree survival and construction practices. Myths abound how trees grow.
Utilization of a Certified Arborist will facilitate everyone's understanding of the needs regarding
trees.
For example, above ground parts of trees are not a "mirror" of what lies below ground. In
actuality, typically four to eleven large roots radiate from the base of a tree's trunk. These
"buttress" roots extend from the root crown and sometimes are visible when the trunk flares
away from the root crown or collar. These large roots decrease in taper rapidly and branch
repeatedly so that at distances of ten feet or more from the trunk, they are about '/2 inch in
diameter or smaller.
These roots grow horizontally through the soil and depending on the tree can extend 40 feet or
more beyond the branch tips. These smaller roots are primarily responsible for water and
mineral absorption. There can be hundreds of roots in a cubic inch of soil thus any Removal of
soil or root severance forces a tree to compromise its physiological processes to sustain the loss.
All trees cannot and should not be preserved.
Trees that are structurally unstable, dead, in poor health, or unable to survive effects of
construction become a liability to the project and may have to be removed. A realistic tree
preservation program acknowledges that conflicts between trees and development or other
PAGE 3 -56 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
construction projects will exist at times and may sometimes result in the Removal of some trees
or Removal of some tree roots and recognizes the detrimental effect to the project and
community when trees die after construction is completed.
Successful tree preservation occurs when construction impacts to trees are considered during the
design process and can then be minimized. The challenge is to determine when impacts will be
too severe for the tree to survive, not only in the short term, but also in the long term. There are
no quantitative methods to calculate this critical level. Determining the optimum TPZ provides a
guideline, although trees often survive and flourish with smaller protection areas.

Matheny, N.P. and Clark, J.R. 1998. Trees and Development
Tree Preservation during development requires the commitment of everyone involved in the
project's planning, design, construction, and management as shown above figure 2.0)
The following are the three guiding principles for tree preservation:
A. Tree preservation cannot be the responsibility of the City of Encinitas staff alone. Each
development participant must understand that his or her activities and decisions influence
the success of tree preservation efforts.
APPENDIX 3.16 PAGE 3 -57
B. The ability to cure construction Injury is very limited, so the focus of preservation efforts
is the prevention of damage to trees. This process starts during the planning and start of
design of the project.
C. The acknowledgement that not all trees are in excellent health or have good structural
stability.
Following the above principles will increase the chance for success and reduce the possibility
that trees will be injured to the point that they will die during construction.
Efforts at preservation must include acknowledgement of the tree and its ecological support
system.
2.10 Planning for All Projects
The City considers trees as important assets and requires plotting tree locations and TPZ on the
plans for all projects whether they are private development, City capital improvement projects,
or private utility company projects. All private development projects or private utility company
projects shall have a Project Arborist which will work with the project manager on developing
TPZs and tree protection strategies. On all City capital improvement projects a Certified Arborist
from the City's Department of Parks and Recreation (i.e. City Arborist) shall be assigned to each
project and will work with the Project Manager on developing TPZs and tree protection
strategies.
2.10.1 Planning and Designing for Private Development and Capital Improvement Projects
Projects are designed by in -house design staff and by outside design firms. Either design team
should be given set of guidelines defining the City's Tree Preservation Policy (Appendix A) and
Tree Protection Guidelines (Appendix B and Appendix D), to assure that trees are accounted for
from project initiation forward.
A. Survey before Planning
The survey must accurately plot the trunk locations within the project site. Include
construction staging areas and delivery routes.
B. Plan and Design with Knowledge of Trees
The health and structural confirmation of the surveyed trees must be evaluated by the
Project Arborist in order to anticipate how well they will respond to development. The
evaluation must describe the character of trees and their suitability for preservation at a
level of detail appropriate for the project and phase of planning. The Project Arborist
must make this evaluation.
C. Plan with a Vision
Disruption of any tree by construction activities may negatively affect its physiological
processes, and cause depletion of energy reserves and decline in vigor, often resulting in
PAGE 3 -58 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
tree death. Typically this does not manifest until many years after the tree is disrupted.
Preservation of mature trees during construction has significant benefits to the success of
a project.
When new trees are planted, consideration should be given to species diversity and
appropriateness of location. To prevent destructive clearance pruning in future years,
keep in mind the ultimate canopy and root spread.
D. Plan for all Aspects and Entire Duration of Project
Construction projects are multi -level and often require participation of various
construction trades and subcontractors. It is important to plan for tree protection with an
understanding of construction site dynamics. Trees must be protected in the staging area,
construction employee parking area, adjacent properties, as well as on the actual
construction site.
2.10.2 Managing In -House Construction Projects
The in -house construction team should be given a set of guidelines that define the City's Tree
Preservation Policy (Appendix A) and Tree Protection Guidelines (Appendix B and Appendix
D), and to assure that trees are accounted for from the project's initiation forward.
A. Survey before Planning
For all in -house projects, contact the City Arborist for an accurate evaluation of trees on
the job site that is to be included in the survey.
B. Plan and Design with Knowledge of Trees
In order to better understand the condition of the affected trees, City Arborist will make
available the results of the tree evaluation. This evaluation will provide you with
knowledge of the resources and the anticipated construction tolerance of the affected
trees.
C. Plan with a Vision
Obtain information about trees and minimize negative impacts on the urban forest.
Conduct all projects with tree preservation in mind.
D. Plan for all Aspects and for the Entire Duration of the Project
Trees must be protected in the staging area, construction employee parking area, and
during demolition and grading. Arrange with the Maintenance Supervisor from the City's
Department of Parks and Recreation for trees to be watered and for the soil to be
protected from Compaction.
2.20 Pre - Construction Requirements - Tree Protection and Preservation Plan
Prior to the commencement of a private development or City Capital Improvement project, the
Project Manager (for either private development or City Capital Improvement project) and
appropriate City staff from the Department of Parks and Recreation, Department of Planning and
Building, Department of Public Works, and the Department of Engineering Services must be
APPENDIX 3.16 PAGE 3 -59
assured that if any activity of the project is within the dripline of City Tree or heritage tree(s), a
site specific tree protection plan is prepared. The following six steps shall be incorporated as part
of the Tree Protection and Preservation Plan:
2.20.1 Site Plan
For all projects, Site Plans must indicate accurately plotted trunk locations and the TPZ of all
trees or group of trees to be preserved within the development area. Additionally, for all
Protected Trees, the plans shall accurately show the trunk diameter, dripline and clearly identify
the TPZ. The type of protective fencing shall be specified and indicated with a bold dashed line.
2.20.2 Protective Tree Fencing for all categories of Protected Trees
Fenced enclosures shall be erected around trees to be protected. This will achieve three primary
goals, (1) to keep crowns and branching structure clear from contact by equipment, materials,
and activities; (2) to preserve roots and soil condition in an intact and non - compacted state and;
(3) to identify the TPZ in which no soil Disturbance is permitted and activities are restricted
unless otherwise approved by the City Arborist or either the Director of Public Works, Director
of Engineering Services Services, Director of Parks and Recreation, or Director of Planning and
Building.
All trees to be preserved shall be protected with five foot to six foot high chain link fences.
Fences are to be mounted on two -inch galvanized iron posts, driven into the ground to a depth of
at least two feet and at no more than ten -foot centers. A two -foot wide access gate for tree
maintenance shall be installed.. Tree fences shall be erected before demolition, grading, or
construction begins and remain until final inspection of the project. "Warning" sign shall be
prominently displayed on each protective fence. The sign shall be a minimum of 8.5 inches x 11
inches and clearly state the following:
TREE PROTECTION ZONE
This Fence Shall Not be Removed
All work within the TPZ requires approval of either the Certified Arborist, the Director of
Engineering Services Services, the Director of Public Works, the Director of Parks and
Recreation, or Director of Planning and Building.
A Type I Tree Protection Fence is for trees to be preserved throughout the duration of the
.project. The fences shall enclose the entire area under the canopy dripline or TPZ, if
specified by the Certified Arborist. If fencing must be located on paving or concrete that
will not be demolished, an appropriate grade level concrete base may support the posts.
B. Type II Tree Protection Fence is for trees situated in small planting areas, where only the
planting area is enclosed with the required chain link protective fencing. The walkways
and traffic areas are left open to the public.
PAGE 3 -60 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
C. Type III Tree Protection Fence is for trees in small tree wells, building site planters or
sidewalk planters. Trees shall be wrapped with 2 inches of orange plastic fencing from
the ground to the first branch and overlaid with 2 -inch thick wooden slats that are bound
securely (slats shall not be allowed to dig into the bark). During installation of the plastic
fencing, caution shall be used to avoid damaging branches. Major scaffold limbs may
also require plastic fencing as directed by the Certified Arborist.
No storage of material, topsoil, vehicles, or equipment shall be permitted within the fenced area
throughout the entire duration of the construction project.
2.20.3 Pre - construction meeting
The Certified Arborist shall attend all pre - construction meetings to assure that everyone fully
understands previously reviewed procedures and tree protective measures concerning the project
site, staging areas, hauling routes, watering, contacts, etc.
2.20.4 Tree Protection Zone
During the design phase of the project the Certified Arborist and the Project Manager will work
together on developing the TPZ for each tree impacted by the project. If an unresolved
disagreement arises between the Certified Arborist and the project manager on the size of a TPZ
for a particular tree, the dispute shall be brought to the Director of Engineering Services, the
Director of Public Works or the Director of Parks and Recreation, who will render a final
decision on the size of the TPZ.
Each tree to be retained shall have a designated TPZ identifying the area sufficiently large
enough to protect it and its roots from Disturbance. The TPZ shall be shown on all Site Plans
including, Demolition, Grading, Irrigation, Electrical, Landscape, etc. Improvements or activities
such as paving, utility and irrigation Trenching including other ancillary activities shall occur
outside the TPZ, unless otherwise specified. The protection fence shall serve as the TPZ.
A. Activities prohibited within the Tree Protection Zone include:
1. Parking vehicles or equipment, storage of building materials, refuse, or excavated
soils, or dumping poisonous material on or around trees and roots. Poisonous
materials include, but are not limited to paint, petroleum products, concrete, stucco
mix, dirty water or any material that may be harmful to tree health
2. The use of tree trunks as a backstop, winch support, anchorage, as a temporary power
pole, signpost or other similar function
3. Cutting of tree roots by utility Trenching, foundation digging, placement of curbs and
trenches, or other miscellaneous excavations without prior approval of either the
Certified Arborist, Director of Engineering Services, Director of Public Works,
Director of Planning and Building, or Director of Parks and Recreation.
4. Soil Disturbance or grade change
5. Drainage changes
B. Activities permitted or required within the Tree Protective Zone
include:
APPENDIX 3.16 PAGE 3 -61
1. Mulch: During construction, wood chips may be spread within the TPZ to a four to
six inch depth, leaving the trunk clear of mulch. This will aid in inadvertent soil
Compaction and moisture loss. Mulch shall be 2 -inch unpainted, untreated shredded
wood or approved material.
2. Root Buffer: When areas under the tree canopy cannot be fenced, a temporary buffer
is required and shall cover the root zone and remain in place at the specified thickness
until the final grading stage. The protective buffer shall consist of shredded wood
chips spread over the roots at a minimum of 6- inches in depth (keeping the trunk
clear of chips), and layered by 3/4 -inch quarry gravel to stabilize the 3 /4—inch plywood
sheets laid on top. Steel plates can also be used.
3. Irrigation, Aeration, fertilization, Mycorrhizae treatments or other beneficial practices
that have been specifically approved for use within the TPZ.
C Erosion Control:
If a tree is adjacent to or in the immediate proximity to a grade slope of 8% or
more, approved erosion control or silt barriers shall be installed outside the TPZ
to prevent siltation and/or erosion within the zone.
2.20.5 Verification of Tree Protection
The project contractor shall verify in writing that all pre - construction tree preservation conditions
have been met as follows:
A. Tree fencing installed
B. Erosion control secured
C. Tree pruning completed
D. Soil Compaction preventive measures installed
E. Tree maintenance schedule established and the responsible party designated
F. Tree Protection Zone (TPZ)
The Project Manager, the Certified Arborist, City's construction inspector, and the contractor
must sign this verification.
2.20.6 Tree Pruning and Removal
Prior to construction, various trees may need to be pruned away from structures or proposed
construction activity. Construction or contractor personnel shall not attempt pruning. Only
personnel approved by the Certified Arborist can perform pruning operations.
Removal of trees adjacent to trees that are to remain requires a great deal of care. Only personnel
approved by the Certified Arborist shall engage in tree Removal. Removal of trees that extend
into branches or roots of protected trees shall not be attempted by the demolition or construction
crew, or by grading or other heavy equipment. Before removing tree stumps, the project
manager shall determine if roots are entangled with trees that are to remain. If so, these stumps
shall have their roots severed before extracting them.
PAGE 3 -62 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
2.30 Activities During Construction and Demolition Near Trees
Soil Disturbance or other damaging activities within the TPZ is prohibited unless approved by
the Certified Arborist and mitigation for specific injuries is implemented. No encroachment
within 5 feet of a trunk will be permitted under any circumstances.
2.30.1 Soil Compaction
Soil Compaction is the largest single factor responsible for the decline of trees on construction
sites. The degree of Compaction depends on several factors: amount and type of pressure
applied, presence and depth of surface organic litter, soil texture and structure, and soil moisture
level.
The greatest increase in soil density occurs during the first few equipment passes over the soil,
which underscores the importance of implementing protective measures before the project begins
and equipment arrives at the site. To dispense traffic weight, mulch and temporarily Root
Buffers can be used.
The following techniques can lessen Compaction: Vertical Mulching, Soil Fracturing, core
venting, and radial Trenching. Do not compact soil to higher density then needed: to 95%
Proctor density (moisture — density) in improved areas for asphalt or concrete pavements, and
not to exceed 85% in unimproved open landscape areas that use water jet Compaction.
2.30.2 Grading Limitations within the TPZ
Lowering the grade around trees can have an immediate and long -term effect on trees. Typically,
most roots are within the top 3 feet of soil, and most of the fine roots active in water and nutrient
absorption are in the top 12 inches.
A. Grade changes within the TPZ are not permitted.
B. Grade changes outside the TPZ shall not significantly alter drainage.
C. Grade changes under specifically approved circumstances shall not allow more than 6
inches of fill soil or allow more than 4 inches of existing soil to be removed from natural
grade, unless mitigated.
D. Grade fills over 6 inches or impervious overlay shall incorporate an approved permanent
aeration system, permeable material, or other approved mitigation.
E. Grade cuts exceeding 4 inches shall incorporate retaining walls or an appropriate
transition equivalent.
The figures below illustrate the pattern of tree root development and areas where encroachments
may have an adverse effect on tree health.

In many parks where trees grow closely together, root systems of individual trees overlap and
intertwine, forming a dense mat of roots.
2.30.3 Trenching, Excavation and Equipment Use
Trenching, excavation or boring within the TPZ shall be limited to activities approved by the
Certified Arborist or either the Director of Engineering Services, Director of Public Works, the
APPENDIX 3.16 PAGE 3 -65
Director of Parks and Recreation, or Director of Planning and Building. Explore alternatives for
Trenching outside the root zone. Avoid exposing roots during hot, dry weather. Backfill trenches
as soon as possible with soil and soak with water the same day. Small roots can die in 10 to 15
minutes and large roots may not survive an hour of exposure. If the trench must be left open all
roots must be kept moist by wrapping them in peat moss and burlap.
If Trenching is unavoidable, the following distances should be maintained:
TRUNK DIAMETER
(measured at 4.5 feet above natural grade)
Up to 6 inches
6 -9 inches
10 -14 inches
15 -19 inches
over 19 inches
DISTANCE FROM BOTH SIDES

15 feet
A. Root Severance. No roots greater than 2 inches in diameter shall be cut without approval
of either the Certified Arborist, Director of Engineering Services, Director of Public
Works, Director of Planning and Building, or the Director of Parks and Recreation.
Tunneling under roots is the approved alternative. Prior to excavation for
foundation /footing/walls, or grading or Trenching within the TPZ, roots shall be severed
cleanly one -foot outside the TPZ to the depth of the planned excavation. When roots
must be cut, they shall be cut cleanly with a sharp saw to sound wood and flush with the
trench site.
B. Excavation. Any approved excavation, demolition, or extraction of material shall be
performed with equipment that is placed outside the TPZ. Hand digging, hydraulic, or
pneumatic excavation are permitted methods for excavation within the TPZ.
C. Heavy Equipment. Use of backhoes, Ditch - Witches, steal tread tractors or other heavy
vehicles within the TPZ is prohibited unless approved by the Certified Arborist, Director
of Engineering Services, Director of Public Works, Director of Parks and Recreation, or
Director of Planning and Building. If allowed, a protective Root Buffer is required.
2.30.4 Tunneling and Directional Drilling
Approved Trenching or pipe installation within the TPZ shall be either cut by hand, air- spade, or
by mechanically boring a tunnel under the roots with a horizontal directional drill using
hydraulic or pneumatic air excavation technology. In all cases, install the utility pipe
immediately, backfill with soil and soak with water within the same day. Tunneling under the
root system can greatly reduce both damage to the tree and the cost to repair landscape and other
features destroyed in the Trenching process. There are times, such as when working in rocky
soils and slopes, when tunneling is not a reasonable alternative.
The following recommendations for tunneling depths should be observed:
PAGE 3 -66 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
TRUNK DIAMETER MINIMUM TUNNEL (DBH)
DEPTH
Less than 12 inches 24 inches
12 inches or more 36 inches
2.30.5 Alternative Methods for Hardscape to Prevent Root Cutting
The following remedies should be considered as an alternative to severing tree roots:
A. Grinding a raised walkway or concrete pad
B. Ramping the walkway surface over the roots or lifted slab with pliable paving.
C. Routing the walkway around tree roots
D. Permeable paving materials (e.g., decomposed granite), interlocking pavers, or flagstone
walkways on sand foundations
2.30.6 Using Alternative Base Course Materials
Engineered structural soil mix is an alternative material for hardscape areas near trees. More
information can be found at www.amereq.com.
2.40 Tree Maintenance During Construction
Providing adequate maintenance can mitigate stressful changes that occur to a tree's environment
during construction. To remain vigorous, the tree needs to maintain stored carbohydrates and
preserve the effectiveness of its growth regulators. It is recommended that large projects provide:
2.40.1 Irrigation
Providing supplemental irrigation for trees under water stress may be the single most important
treatment. Irrigation should be designed to wet the soil within the TPZ to the depth of the root
zone and to replace that water once it is depleted. Light, frequent irrigation should be avoided.
Create a six -inch berm around trees at the edge of the TPZ and fill with no more than six inches
of mulch. Fill the basin with water. Irrigation should wet the top two to three feet of soil to
replicate similar volumes and normal seasonal distribution.
2.40.2 Soil Compaction Mitigation
To prevent negligent encroachment into the TPZ, trees to be preserved during construction must
have the specified type of protection fences in place at all times. Removal of fences, even
temporarily, to allow deliveries or equipment access is not allowed unless approved by the
Certified Arborist and a Root Buffer is installed. The Root Buffer components: mulch, gravel and
plywood, must be maintained continually to assure its effectiveness against soil Compaction.
2.40.3 Dust Control
During periods of extended drought, wind or grading, trunks, limbs and foliage should be
sprayed with water to remove accumulated construction dust.
APPENDIX 3.16 PAGE 3 -67
2.50 Damage to Trees
2.50.1Reporting Injury to Trees
Any damage or Injury to trees shall be reported as soon as possible to the Project Manager or
Construction Inspector, and always to the City Arborist. The City Arborist needs to be aware of
an injured tree in order to monitor its recovery or progress. Injuries to roots and branches must be
repaired immediately using ISA Best Management Practices.
2.50.2 Contractor Subject to Penalties.
If a tree designated to remain is removed or irreversibly damaged as determined by the Certified
Arborist, a contractor may be required to install a replacement tree matching in size, quality and
variety, using an contractor designated by the City Arborist. If an acceptable replacement tree is
not available, the contractor may be required to pay damages to the City for the value of the
damaged tree in accordance with the guidelines set forth in the Guide for Plant Appraisal, 9th
Edition, using the Trunk Formula Method.
2.50.3 Employees Subject to Discipline
In the event of damage to above- or below - ground parts of park trees, the Construction
Supervisor or Park Maintenance Supervisor shall conduct an investigation to determine the cause
of the damage. If it is found that damage was caused due to the error, negligence, or willfulness
of a City employee, then that employee may be subject to appropriate disciplinary action.
2.60 Documents to be Included in all Projects
2.60.1 Model Tree Protection Specifications for Designers and Project Managers (Appendix B).
This document should be distributed to the Planning and Construction Designers, Project
Managers, City Inspectors, bidding contractors, and contracted designing firms.
2.60.2 Tree Protection Summary and Instructions on How to Prevent Damage to Trees During
Construction (Appendix D). This document should be distributed to the Construction and
Maintenance staff for implementation during all in -house projects.
2.70 Right -of -Entry Permits and Documents to be included with every permit
In order to sustain a healthy urban forest, it is imperative that all Department staff understands
the need to protect trees. Every individual, organization or agency issued a Right -of -Entry,
permit or agreement to enter City property, should be in compliance with City policies
concerning protecting trees and be given documentation the will help to ensure tree protection
during the permitted activity. The document titled Instructions on How to Prevent Damage to
Trees During Construction (Appendix D) shall be distributed to every permittee and the
permittee shall comply with these instructions.
PAGE 3 -68 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
SECTION 3.00 — REMOVAL OF TREES
Introduction
A tree may not be removed without City review and approval, except in certain emergencies.
The purpose of City review is to verify that the Removal is warranted and to prevent unnecessary
tree Removal. In most cases, a removed tree must be replaced (although not necessarily in the
same location).
3.10 Tree Removal
A. Allowable Removal
A written permit is required to remove a City Tree, except in emergency situations
outlined in Section 6.00, Hazardous Tree. Removal of Trees is allowed if:
1. A tree is determined to be dead, dying, diseased, hazardous (see Hazardous trees,
Section 6.00), a detriment to or crowding an adjacent tree or a Public Nuisance (see
Section 1.00).
2. A tree trunk is touching or the Basal Flare is under the Building Footprint of an
existing building (for example, uplifting foundation, contact or damage to eaves,
gutters, etc.).
In the case of City Trees, the Department responsible for managing the tree,
either the Public Works Department or the Park and Recreation Department will
issue a written permit approving the Removal of the tree.
In the case of a Heritage Tree shown on previously approved site or landscape
plans, the Planning Commission must approve the Removal before the Director
of Planning and Building will issue a written permit approving the Removal of
the tree (see Heritage Trees, Section 9.10. G); unless deemed an emergency (see
section 6.20).
B. Permit Application
Tree Removal Applications are available at the City of Encinitas, Engineering Sevices
Department Counter at 505 S. Vulcan Ave, Encinitas, CA. 92024. 760 - 633 -2770.
The following is a checklist of items necessary for City review for tree Removal.
Additional information may be required by the reviewing staff. Response will generally
be mailed to the applicant within 10 days. The Removal permit must be on site during the
Removal.

2. Payment of $145.00 review process fee ($125 Schedule Fee and $20
Records Management)
3. Arborist report from a Certified Arborist on company letterhead to include the
following information for each tree:
a. A written narrative describing the tree species (common and scientific);
b. Location (in relation to street, structures and property line);
c. Size (DBH, height & crown spread);
d. Condition (foliage, vigor, structural integrity, etc.);
e. Life expectancy and prognosis (is the tree hazardous, in severe decline, causing
property damage, etc. ?)
C. Hazardous Trees
To remove a tree that is not subject to a permit and has been verified as hazardous, as
defined by these procedures, written approval from the City Arborist is required and must
be available on site when the tree is being removed, unless emergency conditions exit
(see Emergency Removal Conditions, Section 6.20).
D. Notification Requirements
When the City has scheduled a tree for removal the following shall apply:
1. Notice shall be provided to residents in the immediate area 72 hours prior to the
removal (notification may be such means as direct mail and/or door hangers);
2. Notice shall be provided to all interested community organizations, i.e. town councils,
DEMA, etc., in the immediate area 72 hours prior to the removal.
3. The tree to be removed must be clearly marked 72 hours prior to scheduled removal.
In cases when a Certified Arborist has determined that a tree or trees are an
imminent threat to public safety (Hazardous Trees), the City will attempt to notify
the public as appropriate.

SECTION 4.00 - TREE REPLACEMENT
4.10 When Tree Replacement is Required
Certain conditions determine whether or not a tree must be replaced. In summary, they are:
A. City Trees
1. If the City authorizes Removal of a City Tree in connection with a development project,
it shall specify the replacement requirements in the permit authorizing Removal.
2. If a tree is determined to be dead, dying, diseased, hazardous (see Hazardous trees,
Section 6.00), a detriment to or crowding an adjacent tree or a Public Nuisance (see
Section 1.00).
3. A tree trunk is touching or the Basal Flare is under the Building Footprint of an
existing building (for example, uplifting foundation, contact or damage to eaves,
gutters, etc.) a replacement may be required.
B. Heritage Trees
If the City authorizes Removal of a Heritage Tree because it is dead, dying, diseased,
hazardous, or a nuisance, a tree replacement may be required. In all other cases, the tree
must be replaced.
4.20 Tree Canopy Replacement Standards
When a tree is to be replaced, the following standards apply:
A. Species
The replacement trees shall be the same species unless the City Arborist determines that
another species would be more suitable for the location. Factors to be considered include
the long term health of the tree in the location and its compatibility with the adjacent uses
as well as design considerations.
B. Location
The location of the replacement tree shall be approved by the City Arborist. If it is not
possible or desirable to replace the tree on site, the City Arborist shall consider the
distribution of trees so that diversity and age are considered. Section 5.00 (Tree
Planting) will apply.
C. Size and Number
Each tree removed requires 2 x 24" box trees as replacement.
4.30 Tree Value Replacement Standard
When the value of a tree needs to be determined for establishing the amount of security required,
or for any other purpose, the value shall be determined by using the most recent edition of the
Guide for Plant Appraisal published by the Council of Tree and Landscape Appraisers.
APPENDIX 3.16 PAGE 3 -71
4.40 Security Deposits
As a condition of a development approval, the City may require that the developer post security
of between 25% and 100% of the value of the trees to be preserved, as determined by using the
Guide for Plant Appraisal published by the Council of Tree and Landscape Appraisers. The
security may be a cash deposit, letter of credit, or surety bond and shall be filed with the Finance
Department. It shall be in a form satisfactory to the City Attorney. The security shall be posted
before issuance of any grading or building permits. The guarantee period shall be specified; In
general, it shall be at least two years after expected completion of construction. If the trees fail to
survive, the developer shall replace them; if the developer fails to do so, the City may use the
security to provide off site trees and/or landscaping.
PAGE 3 -72 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
SECTION 5.00 - TREE PLANTING
5.10 Introduction
Planting specifications apply for trees that are: 1) planted as a replacement, 2) to be planted as a
City Tree, within the right -of -way or other public land; or 3) planted as part of a landscape plan
subject to Discretionary Development Approval. Using the following specifications will result in
consistent city -wide plantings and superior tree growth and vitality. To achieve this in
development projects, the Landscape Architect shall incorporate these items into their
specifications and the City Arborist will review and approve all plantings.
5.20 Planting Stock and Materials
A. Quality
It is the contractor's responsibility to supply stock that meets ANSI 760.1 -1996.
1. All trees installed within the City of Encinitas shall conform to American Association
of Standards, ANSI Z60.1, Specifications for Acceptance of Nursery Trees at the
Time of Delivery, in all ways.
2. All trees shall be sound, healthy, vigorous, and free of plant disease and insect pests
and their eggs.
3. Container stock shall be grown for at least 8- months in containers in which delivered
and shall not be root bound or have girdling roots.
4. Trees shall not have been topped or headed.
5. Landscape Architect shall inspect and verify, in writing, that all tree material to be
installed on a development site meets the above standards and is acceptable. The City
Arborist will inspect all other plantings of City Trees (e.g. right -of -way, public land,
etc.)
6. The written verification shall be forwarded to the City Planning Department within
one week of acceptance.
7. Inspection shall occur after delivery of stock to the project site.
8. Trees with broken tops, branches or injured trunks shall also be rejected.
B. Miscellaneous Materials
The following materials shall be used unless otherwise specified:
1. Tree stakes. Support stakes shall be treated 2 -inch diameter Lodgepole Pine, two
stakes per tree or approved equivalent. No cross brace shall be used. After
installation, stakes shall be trimmed so that the branches clear the top of the stake.
2. Tree Ties. `V.I.T' Tree Supports (recommended) or equivalent, twist brace, fabric -
reinforced rubber (3/8 -inch minimum), or equivalent approved by the City of
Encinitas shall be used and installed in a figure eight fashion to support the tree to the
stakes.
3. Mulch. Screened untreated wood chips 1/2- to 1- inches in size, spread to a 2 -inch
depth out to the edge of the root ball. The mulch should be kept at least two inches
away from the trunk and shall be applied to each tree (see Mulching, Section 3.45 -G).
APPENDIX 3.16 PAGE 3 -73
4. Root Control Barriers. Use along all public sidewalks, and indicate on approved
plans and drawings. 18 -inch Linear Barrier LB 18 -2 root control barrier shall be used.
Unless specified otherwise, a 10 -foot length shall be placed on center with the tree
and on the sidewalk side only. Root barrier boxes are not approved.
5. Tree Grates. Where sidewalk width is less than 8 -feet and new trees will be installed
in a tree well, metal tree grates shall be used and approved by the City. Minimum size
grates shall be 4' x 4' unless specified otherwise. All tree grates shall be mounted in
frames; frames inset into a concrete foundation within the sidewalk or surface
material and shall be flush with the surrounding surface.
5.30 Planting Site Preparation
A. Soil Preparation and Conditioning
1. All debris, wood chips, pavement, concrete and rocks over 2- inches in diameter shall
be removed from the planting pit to a minimum of 24 -inch depth, unless specified
otherwise (see also Soil Improvement, Section 7.50).
B. Planter Pit
1. Trees in a confined planter pit or sidewalk area: The planting hole shall be excavated
to a minimum of 30- inches deep x the width of the exposed area. Scarify the sides of
the pit (see Planting the Tree, Section 5.40). Soil beneath the root ball shall be
compacted to prevent settling.
2. Trees in all other areas: Excavate the hole's width a minimum of three times the
diameter of the container, and deep enough to allow the root ball of the container to
rest on firm soil. Scarify the sides and the bottom of the pit.
3. The height of the container root ball should be 1 -2- inches higher than grade level (see
Planting the Tree, Section 5.40), except when structural urban tree soil mix is used
(see Alternative Base Course Materials, Section 2.30.6), in which case the tree may
be planted at level grade.
C. Drainage
1. Poor drainage - A percolation test is required to ensure there is adequate drainage for
planting new trees. A minimum of one test per site shall be reviewed with the City
Arborist or Landscape Architect prior to plant installation. One or more of the
following mitigations are required for locations with poor drainage.
a. Mitigation for locations with poor drainage:
L Install french drain. The trench shall radiate away from the tree and be a
minimum of 18- inches in depth filled with drain rock. The grade shall fall
away from the tree trunk.
u. Install drain tiles or perforated pipe directing water away from the tree.
iii. Install a drain chimney at the bottom of the planting pit, a minimum of 4-
inches in diameter and filled with medium sand or fine gravel to ensure
percolation of all water from the filled planter pit. Auger bore drain holes to
penetrate hard pan or clay a minimum of 12- inches into undisturbed pervious
soil. Angle the boring as close to vertical as possible.
PAGE 3 -74 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
2. Planting Percolation Test. A minimum of one test per development site is required.
Additional tests may be needed as required by Landscape Architect or City Arborist.
Fill planting hole with water and insure drainage that is greater than 2- inches per
hour. If percolation is less, one or more of the mitigation measures outlined in Section
7.50 Soil Improvement, must be implemented.
5.40 Planting the Tree
A. Perform percolation test
If the soil is dry, add a few inches of water in the hole. Let it drain before
planting the tree (see Percolation Test, Section 5.30 C).
B. Depth
To check the proper depth of the root ball, place the tree in the hole and lay a
pole or shovel across the original grade - the top of the root ball should be 1
to 2- inches higher.
C. Placing the Tree
Locate the tree in the hole, and if the tree is located near a street right -of -way, rotate the
tree to direct the main branches away from the street side.
D. Filling the Hole
Fill the hole halfway up with original soil or amended soil when approved, and gently
tamp out air pockets with a pole or shovel handle. Add about 1 -inch of water, and let
drain. Fill the rest of the hole to grade, water the fill soil, and let drain.
E. Staking
Place the stakes at the edge of the root ball (drive them 2 -feet into undisturbed ground),
and avoid contact with the branches. If in a windy area, set the stakes in a plane at right
angles to the wind. Remove the nursery stake. Loosely place two ties in a figure eight
around the trunk, as low as needed to hold the tree upright and nail to the stake. Stakes
shall be trimmed so that the branches clear the top of the stake. Do not install a cross -
brace.
F. Berm, Mulch and Water
In non -turf areas, form a soil berm 3 to flinches high at the outermost edge of the root
ball. Place 1 to 2- inches of mulch or bark over root ball and berm, keeping the mulch
away from the trunk a minimum of 2- inches. Fill the berm with water to capacity (see
Watering Schedule, 7.45).
5.50 Planting in Difficult Soil Conditions
A. Turf Areas
In turf areas that receive regular watering, the watering berm may be eliminated after a
few weeks to ensure the tree is receiving adequate water. The turf shall be maintained a
APPENDIX 3.16 PAGE 3 -75
minimum of one foot from the new tree stem, and mulch placed on top of the root ball.
The mulch shall not be touching the tree stem.
B. Alternate Specifications
Occasionally, tree planting must occur in poor or difficult soil where standard planting
techniques will result in poor -to- average performance or mortality (such as unique or
unusual regional geology, slope, soil volume, restrictive physical or chemical properties,
poor drainage, etc.). In this case, the responsible party must investigate alternative
solutions to enable long term tree growth. Alternative planting specifications or plans that
vary from the native or typical soil conditions shall be submitted to the City Arborist for
approval prior to installation.
1. Alternative or specified soils, such as engineered, amended or structural urban tree
soil mix, including written specifications and physical samples, shall be submitted for
approval from the City Arborist and/or Landscape Architect. (see Alternative Base
Course Materials, Section 2.30.6)

CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
SECTION 6.00 - HAZARDOUS TREES
Introduction
The health and safety of a tree are two distinct and separate functional characteristics.
A vigorous and healthy tree may not necessarily be of sound wood or structure. To remove a
dangerous tree, it must first be evaluated and the tree determined to be "hazardous" as defined in
this section. This must be verified in writing by the City Arborist before the tree can be removed.
6.10 Tree Hazards
A. Tree Hazard Responsibility
1. City owned trees on City property that may be a public safety hazard should be
reported to the City of Encinitas, Public Works Department at (760) 633 -2850.
2. On private property, it is the responsibility of the property owner to mitigate or abate
a known hazardous condition of a heritage tree that may be of questionable structure
or deemed as hazardous. Most tree hazards can be prevented with regular checkups
by a tree care professional and timely maintenance action by the property owner. The
City does not require advance permission for removal of heritage trees in
emergencies. However, it does require documentation of the situation after the fact.
This is to avoid the unlawful removal of sound trees on the grounds that they are
hazardous. If there is no immediate danger, and the structural deficiency can be
corrected, it should be. If the City determines that there was no reasonable basis for
believing there was an emergency, the property owner may face penalties for
violating City law (Ordinance).
B. Recognizing Tree Hazards
Determining whether or not a tree's defect /s constitutes a condition that presents an
imminent hazard to an area requires a high degree of knowledge and experience. Hazard
tree assessment should only be evaluated by an arborist who is familiar with tree
physiology and can interpret the external signs of weaknesses; who can perform internal
checks if necessary and recommend mitigation.
6.20 Emergency Removal Conditions
A. Abatement
When a City Tree or Heritage Tree has partially failed (or it is apparent it is about to fail),
and persons or properties are threatened, the tree may be removed without City review or
approval. The City does not require an arborist report before the Removal in this instance.
B. Authorization
Such cases must be substantiated after the fact by the property owner and tree
professional with photographs, abatement information, insurance claim or other relevant
information and completion of a Tree Removal Application. The information is to be
submitted to the City's Planning Department within five days of emergency Removal. All
APPENDIX 3.16 PAGE 3 -77
other authorizations are subject to the standard procedure outlined in Removal of City
Trees or Heritage Trees, Section 3.00.
6.30 Criteria Used by the City to Determine if a Tree is Hazardous
A. Definition of Hazardous
City of Encinitas defines Hazardous' as: an imminent hazard or threat to the safety of
persons or property. If a tree possesses a structural defect that may cause the tree or part
of the tree to fall on someone or something of value (i.e. `Target'), and the condition is
determined to be imminent, the tree is considered hazardous.
B. Evaluation Form
The City uses the national standard, an ISA — Hazard Evaluation Form as a basis to
determine the hazard rating of a tree (see Hazard Rating, Section 6.40). This form, or an
approved equivalent, must be completed by a Certified Arborist. The City Arborist retains
discretionary right to approve, request in writing a second opinion of a rating, in writing,
or recommend action that may reduce the condition to a less -than significant level of
hazard.
C. Authorization
If the hazardous condition or Target cannot be mitigated or reduced to a less than
significant level (see Hazard Reduction and Prevention, Section 6.60) then removal of
the tree shall be authorized by the City, with the exception of an emergency as outline in
section 6.20.
6.40 Determining A Tree's Hazard Rating
For the purpose of Removal, if a tree is declared a hazard it must be rated for the level of hazard
to persons or property by using the Hazard Rating Formula, or other professional methodology
acceptable to the City of Encinitas.
International Society of Arboriculture (ISA) — Hazard Rating Formula.
TABLE 4 -1 Hazard Rating Formula
A. Failure Potential Rating
PAGE 3 -78 APPENDIX 3.16
ISA — Hazard Rating Formula
Failure Potential +Target +Additional = Hazard Rating
Factors /Size of Part
1 =Low 1 =Low 1 =Low 3 =Low
4= Severe 4 = Severs 4 = Severe 4 = Severe
Note: the above factors are combined to quantify a hazard rating. For example, a minimum
rating of 3 is the safest (a low predicable hazard), and the maximum rating of 12 is an imminent
hazard (a high predictable hazard). Furt
her details regarding this formula can be found in the
ISA — Hazard Evaluation Form and the ISA publication *Evaluation of Hazard Trees in Urban
Areas, most current edition.
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
Failures do not occur at random, but are the result of a combination of defects and
aggravating conditions. The scope of the professional evaluation will include structural
defects in the tree (including branches, trunk and roots; and if necessary, shall employ the
use of the most current methods of internal decay inspection available); soil/slope and/or
creek bank stability; individual species susceptibility to failure; pruning; history; decay
weaknesses and any other compromising or pertinent factors considered by the
consultant.
B. Target Rating
Evaluation of potential Targets shall include people, vehicles, structures or something
subject to damage if a tree or part of a tree fails. Property use shall consider what
structures or activities are under or around the tree (e.g. building, parking, pedestrian,
recreational, utility lines, hardscape, etc.). Occupancy shall consider frequency of the use
(occasional, intermittent, frequent or constant), and whether the Target is likely to be
present when failure occurs.
1. Consideration shall be given as to whether the Target can be reasonably removed or
isolated to reduce the hazard rating to a less than significant level. A Target means
people or property (public or private).
2. A tree may be a potential hazard if it is: (a) a tree with the potential to fail; (b) in an
environment that increases the likelihood of failure and; (c) a tree that would strike a
Target.
C. Additional Factors
Evaluation of other factors that contribute to aggravating conditions shall be considered,
such as: size of the affected defect (i.e. a small branch vs. the entire tree uprooting);
significant potential of fire, utility line contact or catastrophic effects, etc.
6.50 Tree Evaluation Checklist
This Section is intended to further help understand tree defects and how they may be interpreted
by an arborist. Many tree defects are not readily apparent because decay or structural damage
may be internal. Also, poor tree health may not reflect poor tree structure. Hazardous trees must
be carefully evaluated. The following checklist of criteria that is typically used by professionals
may indicate potential or current tree hazards. The checklist is not meant to be a comprehensive
guide, however, it is an outline of indicators that may help to indentify potential hazards and
suggest action to avert a tree failure and liability.
A. Hazard Evaluation Questionnaire
Target: If the tree fails and people, vehicles, structures or something subject to damage
than immediate action may be necessary.
Dead Branches: Are there dead tops or branches? Is the tree dead?
APPENDIX 3.16 PAGE 3 -79
Cracks: Are there deep, open cracks in the trunk or branches? These are major starting
points for trunk and branch failure.
Crotch Cracks: Are there deep, open cracks below joining trunks or stems?
Tree Architecture: Has the tree grown beyond its species specific shape into a hazardous
form? Is the tree leaning?
History: Has the tree recently lost large branches?
Edge Tree: Were neighboring trees recently removed, leaving tall trees exposed at the
edge that may be subject to unexpected wind dynamics and blow -over?
Living Branches: Do live branches bend abruptly upward or downward where tips of
large branches were cut off? These may pull out of trunks that are weakened by rot or
cracks. Beware of large branches on rotten or cracked trunks.
Topping: Are large branches growing rapidly from Topping cuts? These sprouts have
weak attachments and may weaken further as they grow. Is there decay below Topping
cuts?
Storm Iniury: Are there broken branches, split trunks, or injured roots? Are branches
close to power lines?
Root Rot: Are there fungus fruit bodies (mushrooms) on roots or near the trunk? Were
roots injured by construction?
Rots and Cankers: Are there hollows or cankers (dead spots) in the trunk or major
branches, some with fungus fruit bodies?
Construction Iniury: Have roots, trunk, or branches been injured?
New Lawn: Is there a new lawn or garden over injured roots? The added fertilizer may
stimulate the growth of fungi that will rot the supporting roots while the top gets heavier.
A moderate storm could cause the tree to fall.
Guying of Trees: Staking and guying of small to medium size trees may benefit from the
additional support. Discretion must be exercised that the guying does not hide
weaknesses, such as toppling over, that result from poor quality nursery stock or girdling
roots.
6.60 Hazard Reduction and Prevention
City staff shall review the following list to reduce hazardous conditions.
1. Plant trees that are not problematic and that fit the site. The International Society of
Arboriculture (ISA) has developed a list to assist you to avoid planting a tree that may
become a problem.
PAGE 3 -80 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
2. A healthy, vigorous tree that receives regular care is less likely to become hazardous than
one that is ignored. Prevention is the best solution to the tree hazard problem.
3. The risk of a hazard tree may be reduced by removing dead and broken branches,
reducing branch end weights, by mechanically supporting weak branches from below, or
by cabling and bracing. In some cases, Targets may be removed such as by moving
picnic tables or other items beneath a precarious tree, fencing to prevent access to such
trees, or rerouting pedestrian or vehicular traffic.
4. If there are no other options to abate the hazard, the tree may need to be removed
entirely.
APPENDIX 3.16 PAGE 3 -81
SECTION 7.00 - TREE MAINTENANCE GUIDELINES
Introduction
This section establishes the minimum standard of care and maintenance of trees for which the
City of Encinitas is responsible. These standards apply to all persons who own or are engaged in
the business of repairing, maintaining, or preserving these trees. The following standards of care
are set forth for pruning (including utility, fire and traffic encroachment), planting, watering, soil
and nutrient requirements, insect, disease, and fruit control.
7.10 Care of Trees
All owners of City Trees and Heritage Trees are to follow the required maintenance standards set
forth in this Manual. If special pruning or situations require a variance from these standards, it is
the responsibility of the Project Arborist, property owner or other City staff to clarify why the
changes are needed and review them with the City Arborist.
In addition to following standards for care, the City will maintain an electronic inventory of all
City trees and Heritage trees. The inventory will document, at a minimum, the tree species (both
botanical and common name), location, and maintenance records.
7.15 Prohibited Acts
Improper maintenance of City Trees and Heritage Trees may constitute a prohibited act as
defined by the City of Encinitas Municipal Code Chapters 15.04 and 15.08 and may constitute a
violation which may be subject to penalty.
The following prohibited maintenance practices for City Trees and Heritage Trees apply.
A. Excessive Pruning
Except for clearance pruning of utility lines, or abating a Public
Nuisance, Excessive Pruning shall be considered a prohibited act.
B. Topping
Topping shall be considered a prohibited act. Seek alternatives to Topping.
C. Other prohibited actions
Taking any action foreseeable leading to the death of a tree or permanent damage to its
health, including but not limited to Excessive Pruning, cutting, girdling, poisoning, over
watering, unauthorized relocation or transportation of a tree, posting signs or other
objects on a tree, unless authorized through an approved construction permit that includes
a Tree Protection and Preservation Plan. No trenching, excavating, altering the grade,
or paving within the Dripline Area of a tree shall be permitted.
PAGE 3 -82 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
7.20 Standards for Pruning Trees
The most compelling reason to prune trees is to develop a strong, safe framework. All work to be
performed on trees shall be in accordance with the following standards.
A. Specifications
All specifications for working on City Trees and Heritage Trees shall be written and shall
be administered by a qualified arborist, and shall be designed to promote the preservation
of tree structure and health.
B. Industry Standards
All work on trees shall be in accordance with the most current edition of the ANSI
standards including: ANSIA300 -199, Safety Standards, ANSI Z133.1 -1994, and Pruning
Standards Appendix F).
7.25 Pruning Mature Trees
There are six types of pruning that may be required for use on mature trees (see ISA Pruning
Guidelines, Appendix F). Prior to entering the tree, the tree worker is required to be familiar with
these types of pruning as stated in the Performance Standards, ANSI, A300 -1995. `Species -
specific' pruning promotes the natural shape of the tree (i.e. excurrent, decurrent, vase - shaped,
fast growing, etc.).
A. Types of Pruning
1. Crown Cleaning
2. Crown Thinning
3. Crown Raising
4. Crown Restoration
5. Crown Reduction
6. Utility Pruning
B. Tree Injury
Climbing and pruning practices shall not injure the tree except for the pruning cuts.
7.30 Recycle Green Waste
As a part of standard tree maintenance and care tree trimmings are generated. This material
should be reused (chipped) or recycled whenever possible.
7.35 Pruning Distressed Trees
Distressed trees require as much leaf area as possible to overcome stressed conditions.
To avoid additional Injury, the following measures shall be followed for these trees.
A. Injury or Disturbance
APPENDIX 3.16 PAGE 3 -83
If a tree has been damaged by Injury or Disturbance, delay pruning until deadwood
becomes evident (typically 1 -3 years after Injury). Crown cleaning is then recommended.
B. Neglect
Trees that have received little or no care or maintenance may need moderate crown
thinning, reduction of end weights or entire crown restoration.
7.40 Pruning Young Trees
The average life expectancy for trees growing in harsh urban conditions is 7 -10 years. Pruning
trees early will improve life expectancy and is a proven, cost - effective measure. Added benefits
are also reflected in safer trees with fewer branch failures. Trees shall be pruned in the following
way:
A. Young trees should be pruned during the second year after planting to improve their
structure, and only minor crown cleaning every 3 -7 years thereafter. Refer to ISA Pruning
Standards (see Appendix P).
B. Do not top the main leader except to position the lowest main branch. Other main
branches should be spaced at least 18- inches apart to alleviate a tight grouping branches.
C. Select permanent branching and allow temporary low branching on the lowest part of the
trunk to remain.
7.45 Fertilizing Standards
This section outlines performance standards for fertilizing, and applies only if fertilizing is
specified by the City Arborist. Fertilizing mature trees is generally not necessary. Fertilizing may
be specified for trees that will be impacted by upcoming Disturbance, grade changes or a
modified environment. Benefits gained from the increase stored resources may aid to the tree
overcoming the stress caused by Disturbance.
A. Specifications
Fertilizing, if specified, shall be performed to the following standards:
1. Method of application: The method shall be subsurface injection, on approximate a-
foot centers (within the root ball on young trees; 2 -feet out on older trees) and out to
the approximate Dripline perimeter. Specific situations may justify other variations
such as vertical mulch, soil - fracture or surface- broadcast methods.
2. Material and Rates: Unless specified otherwise, fertilizer formula shall be a slow -
release, complete fertilizer with chelate trace elements (e.g. 22 -14 -14 or 20- 20 -20)
and mixed at label rates not to exceed 4- pounds nitrogen per 100 - gallons of water.
Extraordinary cases may require soil and tissue sampling to correct Target
deficiencies.
PAGE 3 -84 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
3. Amount: Unless specified otherwise, volume shall be determined by mixing 10-
gallons of water per inch of trunk diameter when measured at 54- inches above natural
grade.
4. Timing: Timing should not be detrimental to tree health. Best results are derived from
applications made during the prior growing season. Apply fertilizer between May
through September for best results.
7.50 Watering Schedule
Newly installed trees planted, including drought tolerant species, are dependent upon
supplemental irrigation until established, typically for two years. Periods of extreme heat, wind
or drought may require more or less water than recommended in these specifications. The
method and amount that is applied may vary depending upon soil composition, heat, wind,
planted in turf or ground cover, periods of abnormal rainfall or in poorly drained soils (see
Drainage, Section 5.30). The watering of trees or their replacements shall follow these standards:
A. New trees
During the establishment period (1 -2 years), trees should be watered thoroughly to their
root depth as frequently as needed. A watering schedule is to be submitted at the
preconstruction meeting for tress planted as part of a development project. The schedule
is to include altering frequency and quantity. The minimum standards shall be as follows:
1. 1 -3 months in the ground: 4 times per month or as necessary
2. 4 -6 months in the ground: 2 times per month or as necessary
3. 7 -12 months in the ground: 1 time per month or as necessary
B. Mature trees
1. Most species: 1 time per month during irrigation season (usually March through
September)
2. Coast Live Oak, Valley Oak and Blue Oak: deep water in May and September do
not water during other months. For oaks already in the vicinity of irrigated conditions,
automatic sprinklers or regular watering shall not be allowed to spray on or within
three feet of the trunk. The water shall not be allowed to pool or drain towards the
trunk.
C. Watering Methods
The following options shall fulfill the watering requirements. One or more of the
following may be utilized dependent upon unique circumstances subject of the City
Arborist determination. The options are as follows:
1. Automated Watering Systems. All new City Trees planted within the right -of -way
shall be provided with one of the following automatic watering systems. Other city
maintained systems shall be per the City Arborist's approval.
APPENDIX 3.16 PAGE 3 -85
2. Bubbler heads (Preferred). One or two bubbler heads mounted on notes: flexible
tubing are to be placed adjacent to or on top of the root ball. The placement of
bubbler within an aeration tube is not allowed.
3. Drip Loop system. A continuous loop of drip tubing circling around the trunk at a
point two- thirds out from the trunk to the edge of the root ball (for new trees 36 -inch
box size and greater, a second loop of drip tubing is required at a point just beyond
the root ball on native soil).
4. Hand watering systems. Recommended for trees that are part of a development
project that must be watered to insure tree survival during the course of construction
until automatic irrigation is installed.
4. Flood watering. Newly installed trees must be `flood or basin watered' on top of the
root ball to allow the water to infiltrate through the root zone.
5. Subsurface injections using a hydraulic spray pump (practical for use in hard,
compacted soils or steep hillsides).
6. Soaker hose. Slow, deep watering using a garden type soaker hose.
7. Wetting agent. A root ball that has been allowed to dry out beyond the wilting point
shall require the addition of a wetting agent to the water (such as Aqua -grow or
equivalent).
D. Amount
Unless otherwise specified, the volume of water applied at each irrigation should be in
the range of 10- gallons per inch of trunk diameter when measured at 54- inches above
natural grade. The final decision of whether to water or not should be based on accurate
soil probe samples that are taken from the root ball.
7.55 Soil Improvement
During development, Compaction of the soil is the largest single factor responsible for the
decline of oaks and older trees. Ninety percent of the damage to the upper eighteen inches of soil
occurs during the first pass of heavy equipment and cannot be reversed. Every effort to avoid
Compaction of soil porosity within the TPZ shall be taken at all times. When required by the
conditions of Discretionary Development Approval for a project or as mitigate on for Injury or a
prohibited action, the following performance standards for improvement of compacted or
damaged soil shall be implemented:
A. Aeration
Soil that is damaged or compacted within the Dripline of a tree shall be loosened or
aerated to promote root growth and enhance tree vitality. One of the following aeration
methods shall be specified an in effort to correct compacted soil conditions:
1. Vertical Mulching: auger holes 2 to 4 -inch diameter, 2 to 3 -feet deep, on 4 -foot
centers and backfilled with porous material such as perlite, vermiculite or volcanic
rock.
PAGE 3 -86 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
2. Radial Trenching with an air excavator: excavate a soil trench 3 to 6- inches wide and
a minimum of 12- inches deep from (approximately) 3 -feet from the trunk out to the
Dripline area. The trenches shall radiate out from one foot apart at the closest point.
3. Soil fracturing with a pneumatic air -driven device
4. Subsurface injections under moderate hydraulic pressure using a three foot probe and
applied on 3 -foot centers under the Dripline.
B. Drainage
Adequate drainage must be provided to the surrounding soil for the planting of new trees.
If the trees are to be planted in impermeable or infertile soil, and water infiltration rates
are less than 2- inches an hour, then one of the following drainage systems or other
approved measures must be implemented (see Drainage, Section 3.40 -C).
1. French drain, a minimum of three feet in depth
2. Drain tiles or lines beneath the trees
3. Auger six drain holes at the bottom perimeter of the planting pit, a minimum of 4-
inches in diameter, 24- inches deep and filled with medium sand or fine gravel
7.60 Insect and Disease Control
Generally, insect populations do not threaten tree health to the point of mortality. More often,
when their populations become too great they create a nuisance. For example, scale on tulips or
aphids feeding on purple leaf plums produce sticky honeydew that may be a nuisance if dripping
on cars or at a storefront entry. Occasionally, pests such as Oak or Tussock Moth larvae can
defoliate and severely damage a tree. If action is warranted, Integrated Pest Management (I.P.M.)
suggests that the pest source be identified and Targeted with a specific and timely treatment. If
insects or disease can lead to the death of a tree, then it is the responsibility of the owner to
evaluate the condition according to the following guidelines and treat the problem in a timely
fashion to prevent further deterioration of the tree.
A. Insects
For treatment, consult a pest control operator that is licensed by the California
Department of Pesticide Regulation. Accurate timing is critical for success.
1. Nontoxic materials should be used whenever possible to control leaf- chewing insects
B. Disease and Decay - above ground
Disease such as heart-rot decay that erodes the health or weakens the structure of a tree
may compromise the safety of people or property. It is the owner's responsibility to
correct a known hazardous condition in a timely fashion. Consult with a Certified
Arborist for remedy possibilities, for example, pruning out infected branches, thinning, or
the spray application of a chemical treatment.
C. Disease - below ground
Soilbome diseases, such as Oak Root Fungus (Armillaria mellea) or Root Rot
(Phytophthora sp. ), can be present in soils. Often, a poor landscape design surrounding
APPENDIX 3.16 PAGE 3 -87
old trees encourages harmful and often lethal diseases. The following conditions that
favor a disease environment must be avoided:
1. Conditions to avoid:
Compacting of the soil within the tree's Dripline, adding fill dirt, rototilling,
Trenching, removing soil from the tree root area, and excessive or regular watering
on or near the tree trunk area and planting incompatible water - loving plants within
the tree's Dripline. Combined with poorly - drained soil, these factors often activate
normally dormant fungi to become opportunistic and infect the tree to cause the
decline and eventual death of the tree. This decline can be slow and may not be
evident for many years.
2. Landscape Design:
When planning landscaping around a tree, an evaluation of the tree and soil must be
performed to determine if there is a disease present. If the tree is diseased and
landscaping will contribute to decline, permanent damage or render it hazardous, it is
the obligation of the property owner to take reasonable measures to reduce or
eliminate the conditions that may cause the decline of the tree.
3. To identify cultural conditions that may lead to diseases such as Oak Root Fungus,
Verticillium, Phytophthora or other soilbome fungi, review the Sunset Western
Garden Book or consult with a Certified Arborist.
D. Foliar disease
Leaf spot or galls may be chronic or reoccur during specific seasons. Though many of
these diseases destroy leaf tissue and become unsightly, they may not significantly reduce
the trees health and therefore need not be treated.
7.65 Fruit Control
While all trees produce flowers or fruit of some kind, some trees can be considered a nuisance if
the use area is not compatible with the litter generated by the tree. For example, the dropping
fruit of the European Olive (Olea europaea), American Sweet Gum (Liquidamber styraciflua),
or acorn drip of a Holly Oak (Quercus ilex) may be a safety hazard if it is in the proximity of a
handicap ramp or other high pedestrian area and will thus justify control measures. Control can
only be successful if materials are applied carefully at optimum timing. For treatment to control
the situation, consult a pest control operator that is licensed by the California Department of
Pesticide Regulation.
PAGE 3 -88 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
SECTION 8.00 - TREE REPORTS
Introduction
An arborist report is needed for; development projects, tree Removal permits requested by
private property owners and when tree removals are recommended by the City staff. The report
must be prepared by a Certified Arborist for the applicant and submitted to the City for the
purpose of providing accurate information and opinions regarding the condition, welfare,
maintenance, preservation or value of tree.
8.10 When a Written Report is Required
Generally, there are three circumstances in which Tree Reports are required: 1) When a tree
removal permit is sought by a private property owner to remove a City Tree or a heritage tree,
and 2) to complete and verify a Site Plan, assess tree impacts and establish tree protection for
property development within the drip line of a City Tree or heritage tree, and 3) When the City
has determined that a City Tree needs to be removed. The types of report formats are: Letter
Report, Tree Survey, Tree Protection and Preservation Plan and Tree Appraisal.
8.20 Who May Prepare the Report
Reports are to be prepared by a Certified Arborist retained by the applicant, property owner or
the City. This person shall possess a current ISA certification; be a member of the American
Society of Consulting Arborists; or a member of good standing in another nationally recognized
tree research, care, and preservation organization.
8.30 Reports for Individual Tree Removal Permit
A. Tree Removal Permit
The procedure involves three steps which must be completed and approved to remove a
City Tree or a heritage tree. The information contained within the application will be
reviewed by the City Arborist for written response.
B. Submittals
For this purpose, the following information is to be submitted to the City for review:
1. Application: A completed application for the Tree Removal.
2. Filling Fee: A filing fee of $145 (Application fee - $125, records management $20).
3. Arborist Report: An arborist report prepared by a Certified Arborist.
C. Written authorization
To remove a City Tree (on city land or in the street right -of -way), the property owner
shall first have obtained written permission from Public Works Department or City
Arborist. For a Heritage Tree on private property, the permit from the Planning Division
must be on site when the tree is being removed. For a trees removed as part of a
APPENDIX 3.16 PAGE 3 -89
development project, the approved plans serve as the approval and no separate written
permit is needed.
8.40 Types of Reports

assessing multiple trees. The report is to be on letterhead stationery of the individual
preparing the report, including their ISA Certification number.
i. Removal:
If for a tree Removal (i.e., an application request for Removal only, not in
connection with a property development), the report shall provide information and
determination whether the tree /s are dead, hazardous or constitutes a nuisance.
ii. Development:
If for development on a single family residential lot (not a subdivision), the report
shall also clearly indicate whether or not any Heritage Treels or City Tree is so
close to the `Building Area or Building Footprint' that it will be killed or
permanently injured by Disturbance. The report must make specific
recommendations to protect and preserve the tree during the course of
construction that are consistent with the specifications within this Manual

8.50 Tree Protection and Preservation Report
All publicly owned or Heritage Trees to be retained on a development site shall be shown on
approved sets of civil, building and landscape plans and shall be protected during the
construction process. A Tree Protection and Preservation Plan submitted for review by the
Planning and Building Department is required when trees to be saved may be injured by
Disturbance. The tree preservation plan shall assume compliance with standards in Section 2.00
of this Manual (see Protection of Trees During Construction, Section 2.00). In addition, the
following submittal information must be included in the report:
A. Scope & Construction Phasing
The Tree Protection and Preservation Plan shall identify, but not be limited to, written
recommendations for the health and long -term welfare of trees that are to be followed
during the following distinct phases and conditions: preconstruction; during construction,
post construction, demolition activities; methods of avoiding Injury, damage treatment
and inspections. Schedules shall be included.
APPENDIX 3.16 PAGE 3 -91
B. Tree Protection Zone
The Tree Protection and Preservation Plan shall establish a TPZ for each tree to be
fenced and clearly outline site - specific measures for protection of the trees during

construction. After project approval, any changes to the protection measures must be
approved in writing, by the City Arborist. The tree protection plan shall include the
following Site Plan elements:
8.60 Site Plan
A. Disclosure of all trees on and near the site
The property owner or designee shall provide accurate information to the Project
Arborist to develop the tree protection measures and to enable accurate recommendations
to insure their survival. This Site Plan shall accurately show the surveyed location,
species, size of trunk and leaf canopy; show the drip line of any neighboring trees that
may overhang the site and publicly owned trees that are within 30 -feet on each side of the
project. Failure to show a tree on the plans and later determined to be affected by
construction may require the work to stop until mitigation can be agreed upon by the
property owner and the City.
B. Plans submitted to the City
In addition to the above information, final improvement plans shall include and show the
following information: show the TPZ of any tree to be retained and denote a 5 -foot chain
link type fencing around the protected zone of each tree or group of trees (to be clearly
identified as such on all plans as a bold- dashed line); permeable paving located within the
drip line area; approved utility pathways; grade changes; surface and subsurface drainage
and aeration systems to be used; walls, tree wells, retaining walls and grade change
barriers, both temporary and permanent; landscaping and irrigation within drip line of
trees.
C. Plans must show tree protection
Protective Tree Fencing identified within the arborist report, both written and
diagrammatic, shall be clearly shown as a bold, dashed line on the approved Site Plans
submitted for demolition, grading, construction, building permit or any other aspects that
are relevant to the project.
8.70 Tree Appraisal
Landscape value typically contributes to the value of a property. An individual tree has an
inherent value to the property that can be determined by an appraisal prepared by a Certified
Arborist. An appraisal is a process for determining a monetary opinion of the value of a tree as it
relates to the property, a group of trees and/or the immediate community. A qualified Certified
Arborist is required to determine this value, and must exercise good and fair judgment by
adjusting the basic value by the tree's condition and location. There are two methods to
determine tree value; (1) the Replacement Method, based upon the size and availability of the
PAGE 3 -92 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
replacement tree or, (2) the Trunk Formula Method, if the tree cannot be replaced (e.g. not
sufficient room on site or it is too large to replace). In all cases, the type of formula used must be
identified.
8.80 Appraisal Methods
The Certified Arborist must prepare the appraisal by using the most current edition of (1) the
`Guide for Plant Appraisal', published by the Council of Tree and Landscape Appraisers, and (2)
the most recent Form for Northern California' established by the International Society of
Arboriculture.
A. The Replacement Cost Method
This method applies to smaller trees with a trunk size up to 4- inches in diameter or, 48-
inch box size trees (replaceable.) For this method, the appraised value shall be
determined by combining: price quote + transportation + planting + other costs and
applying the condition and location value to the tree. The sum
B. The Trunk Formula Method notes:
Applies to trees that are too large for practical replacement (transplanting) and shall be
appraised by: determining the basic tree value and adjusting this value by a condition and
location ratings. The appraised value shall be determined by using the most recent edition
of the `Guide for Plant Appraisal', published by the Council of Tree and Landscape
Appraisers. The Trunk Formula or Replacement Method Forms for Northern California
established by the International Society of Arboriculture must be used to compute the
appraised value. All trees with a stem larger than 4- inches in diameter when measured at
12- inches above natural grade shall be calculated in this manner.
APPENDIX 3.16 PAGE 3 -93
SECTION 9.00 - HERITAGE TREES
9.10 Designation of Heritage Trees
A. Upon nomination by any person or agency and with the written consent of the property
owner(s), a tree or trees may be designated as a Heritage Tree or trees. Heritage Trees
may be located on City or private property.
B. Nominations for a Heritage Tree shall be reviewed by the Environmental Advisory
Commission (EAC) and the EAC shall make a recommendation on Heritage Tree
nominations to the Planning Commission.
C. The Planning Commission may designate a tree as a Heritage Tree upon a finding that it
is unique and of importance to the community due to any of the following factors:
1. It is one of the oldest and largest of its species located in Encinitas;
2. It is a tree of unique form or species;
3. It has historic significance due to an association with an historic building, site, street,
person or event; or
4. It is a defining landmark or significant outstanding feature of a neighborhood.
D. Upon Planning Commission approval, the tree(s) shall be designated as a Heritage
Tree(s). Any work on or in the vicinity of a designated Heritage Tree shall be done in
accordance with this Manual and under the provisions of a City- issued permit. The
requirement for a permit may be waived in cases of hazardous trees or other cases where
immediate action must be taken for public health or safety reasons.
E. After Planning Commission approval of a Heritage Tree designation, the City shall notify
the property owner(s) in writing. A listing of trees so designated, including the specific
locations thereof, shall be kept by the City.
F. It shall be the responsibility of any private property owner whose property contains a
Heritage Tree to insure that any future owners, successors, heirs, personal
representatives, transferees and/or assigns of said property owner knows of the
designated Heritage Tree(s) and the requirements that come with this designation.
G. Once designated, a Heritage Tree shall be subject to the provisions of this Manual unless
removed from the list of Heritage Trees by action of the Planning Commission. The
Planning Commission may remove a tree from the list upon its own motion or upon
written request by the property owner. Request for such action must originate in the
same manner and proceed through the same process as nomination for Heritage Tree
designation.
H. Any person may appeal the designation of a tree or trees as a Heritage Tree(s), or the
Removal of such designation, in accordance with the procedures set forth in Chapter 1.12
of the Municipal Code (Appeals).

APPENDIX 3.16 PAGE 3 -95
SECTION 11.00 —ENFORCEMENT
11.10 Prohibited acts
It shall be a violation of the Urban Forest Management Program policy for anyone to remove or
cause to be removed a City Tree or a Heritage Tree, except as allowed in this section:
A. In the absence of development, City Trees or Heritage Trees shall not be removed unless
determined by the Director of Public Works, on the basis of a Tree Report prepared by a
Certified Arborist for the applicant and other relevant information, that the tree should be
removed because it is dead, is hazardous, is a detriment to or crowding an adjacent City
Tree or Heritage Tree or constitutes a Public Nuisance as defined in this Manual, except
when an emergency removal is needed (Section 6.20).
B. In the case of development on a single - family residential lot, other than in connection
with a subdivision:
1. City Trees or Heritage Trees shall not be removed unless the trunk or Basal Flare of
the tree is touching or within the Building Footprint, or the Director of Planning and
Building has determined, on the basis of a Tree Report prepared by a Certified
Arborist for the applicant and other relevant information, that the tree should be
removed because it is dead, is hazardous, is a detriment to or crowding an adjacent
trees, or constitutes a Public Nuisance as defined in this Manual.
2. If no Building Footprint exists, City Trees or Heritage Trees shall not be removed
unless the trunk of the tree is located in the Building Area, or the Director of
Engineering Services has determined, on the basis of a Tree Report prepared by a
Certified Arborist for the applicant and other relevant information, that the tree
should be removed because it is dead, is hazardous, is a detriment to or crowding an
adjacent City Trees or Heritage Trees, or constitutes a Public Nuisance as defined in
this Manual.
3. If Removal is allowed because the tree trunk is located in the Building Footprint, or
the trunk or Basal Flare is in the Building Area, or because the Director of
Engineering Services has determined that the tree is so close to the Building Area that
construction would result in the death of the tree, the tree removed shall be replaced
in accordance with the standards in the this Manual.
C. In connection with a proposed subdivision of land into two or more parcels, no City Trees
or Heritage Trees shall be removed unless Removal is unavoidable due to restricted
access to the property or deemed necessary to repair a geologic hazard (landslide, repairs,
etc.). The tree removed shall be replaced in accordance with the standards in this Manual.
Tree preservation and protection measures for any lot that is created by a proposed
subdivision of land shall comply with the regulations of this Manual.
D. In all circumstances other than those described in paragraphs A, B and C of this section,
City Trees or Heritage Trees shall not be removed unless one of the following applies:
1. The Director of Engineering Services, the Director of Parks and Recreation or the
Director of Public Works has determined, on the basis of a Tree Report prepared by a
Certified Arborist for the applicant and other relevant information, that the tree
should be removed because it is dead, dangerous or constitutes a Public Nuisance as
defined in this Manual. In such cases, the Dripline area of the removed tree, or an
PAGE 3 -96 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
equivalent area on the site, shall be preserved from development of any structure
unless Removal would have been permitted under paragraph (2), and tree replacement
in accordance with the standards in this Manual shall be required.
2. Removal is permitted as part of a discretionary development approval. In such a case,
the approval shall be conditioned upon replacement in accordance with the standards
in this Manual.
11.20 No Limitation of Authority Under Title 30
Nothing in this Manual limits or modifies the existing authority of the City under Title 30
(Zoning Ordinance) to require trees and other plants not covered by this Manual to be identified,
retained, protected, and/or planted as conditions of the approval of development. In the event of
conflict between provisions of this Manual and conditions of any permit or other approval
granted pursuant to Title 30, the more protective requirements shall prevail.
11.30 Care Of City Trees or Heritage Trees
A. All owners of property containing City Trees or Heritage Trees shall follow the
maintenance standards in this Manual.
B. The standards for protection of trees during construction contained in this Manual shall

Management Program policy by the issuance of citations: Building Official, Assistant Building
Official and Code Enforcement Officer.
11.50 Enforcement - Remedies for Violation
In addition to all other remedies set forth in this code or otherwise provided by law, the
following remedies shall be available to the city for violation of the Urban Forest Management
Program policy:
A. Stop Work - Temporary Moratorium.
1. If a violation occurs during development, the city may issue a stop work order
suspending and prohibiting further activity on the property pursuant to the grading,
demolition, and/or building permit(s) (including construction, inspection, and issuance
of certificates of occupancy) until a mitigation plan has been filed with and approved
by the Director of Planning and Building, agreed to in writing by the property
owner(s), and either implemented or guaranteed by the posting of adequate security.
The mitigation plan shall include measures for protection of any remaining trees on the
property, and shall provide for replacement of each tree removed on the property or at
locations approved by the Director of Planning and Building or by the Director of
Public Works, if replacement is to occur on public property. The replacement ratio
APPENDIX 3.16 PAGE 3 -97
shall be in accordance with the standards set forth in this Manual and shall be at a
greater ratio than that required where tree Removal is permitted pursuant to the
provisions of this Manual.
2. If a violation occurs in the absence of development, or while an application for a
building permit or discretionary development approval for the lot upon which the tree
is located is pending, the Director of Planning and Building may issue a temporary
moratorium on development of the subject property, not to exceed eighteen months
from the date the violation occurred. The purpose of the moratorium is to provide the
city an opportunity to study and determine appropriate mitigation measures for the tree
Removal, and to ensure measures are incorporated into any fixture development
approvals for the property. Mitigation measures as determined by the Director of
Planning and Building shall be imposed as a condition of any subsequent permits for
development on the subject property.
B. Civil Penalties.

penalty in an amount not to exceed five thousand dollars ($5,000.00) per violation.
2. Where the violation has resulted in Removal of a tree, the civil penalty shall be in an
amount not to exceed five thousand dollars ($5,000.00) per tree unlawfully removed,
or the replacement value of each such tree, whichever amount is higher. Such amount
shall be payable to the city. Replacement value for the purposes of this section shall
be determined utilizing the most recent edition of the Guide for Plant Appraisal,
published by the Council of Tree and Landscape Appraisers.
C. Injunctive Relief. A civil action may be commenced to abate, enjoin, or otherwise compel
the cessation of such violation.
D. Costs. In any civil action brought pursuant to this Manual in which the city prevails, the
court shall award to the city all costs of investigation and preparation for trial, the costs of
trial, reasonable expenses including overhead and administrative costs incurred in
prosecuting the action, and reasonable attorney fees.
11.60 Fees
Tree Reports required to be submitted to the city for review and evaluation pursuant to this
Manual shall be accompanied by the fee prescribed therefor in the municipal fee schedule.
11.70 Severability
If any provision of this Manual or the application thereof to any person or circumstance is held to
be invalid by a court of competent jurisdiction, such invalidity shall not affect any other
provision of this Manual which can be given effect without the invalid provision or application,
and to this end the provisions of this Manual are declared to be severable.
PAGE 3 -98 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
11.80 Appeals
Any person seeking the director's approval to remove a City Trees or Heritage Trees pursuant to
the regulations in this Manual who is aggrieved by a decision of the Director of Planning and
Building or the Director of Public Works may appeal such decision in accordance with the
procedures set forth in Municipal Code Chapter 1.12 (Appeals).
APPENDIX 3.16 PAGE 3 -99
Appendix A
TREE PRESERVATION POLICY
Purpose
The purpose of the Tree Preservation Policy is to establish a regulatory tool to provide orderly
protection of specified trees, protect their value, and avoid significant negative impacts to the
ecosystem. The Policy regulates protection of trees in two categories: City Trees and Heritage
Tree.
Heritage Trees:
Heritage trees are individual trees of any size or species that are specifically designated as
heritage because of their historical, commemorative, or horticultural significance. The list of
designated Heritage Trees remains open for new designations and provides useful information to
the City of Encinitas staff regarding the importance of their actions while planning activities near
heritage trees. Since Heritage Trees are protected trees, recommendations from the City
Arborists must be obtained before any alterations to the protected trees is made that may cause
the trees to become damaged, relocated, or removed. The City Arborist, Director of Engineering,
Director of Parks and Recreation, Director of Public Works, or Director of Planning and
Building must approve the recommendation before any action proceeds. Pruning also can cause
irreversible damage to the tree and must be in compliance with the ISA Tree Pruning Guidelines.
Pruning must be performed under supervision of an ISA certified staff only. If the tree poses an
immediate threat to life or public safety, the City Arborist may compromise the process, if proper
documentation, including digital photographs, is kept. Heritage trees identified as dead by the
City Arborist will be removed and recorded into the designated Heritage Trees list. The Heritage
Trees list can be obtained from the City of Encinitas Department of Parks and Recreation.
City Trees
Most City trees have great value beyond the shade they provide. They are a scenic resource to
surrounding neighborhoods and their removal or disfigurement by extreme pruning for
construction clearance or other reasons diminishes the value of the urban forest and often
provokes public protest. Some trees have not been designated under a protected group of trees
but still provide aesthetic, sentimental, economical, and environmental value. The large number
of trees in our City has a significant cooling effect on the urban environment in Encinitas, where
tree canopy represents only 25% the land. Every tree in our City is recognized as a valuable
asset. This Manual provides guidelines for protecting trees during construction and offers

TREE PROTECTION GUIDELINES FOR DESIGNERS AND PROJECT MANAGERS
Model Tree Preservation Specifications
These specifications shall be made a part of all construction documents. They were developed in
order to protect all trees that have either direct or indirect encroachment into their driplines
during construction within City parks. The City Arborist shall be invited to the Job Start Meeting
and also notified 48 -hours prior to start of construction. They may be contacted at
(760) 633 -2740.
General Requirements
1. No equipment is to be operated or parked under a tree, nor is any material to be stored
within the dripline of a tree or leaned against a tree trunk. Do not pile or compact soil
within a dripline.
2. In areas of construction, protect soil surface from traffic compaction with 3" of mulch or
overlapping 3/4" plywood sheets.
3. No surface irrigation shall be installed within the dripline of a tree.
4. All work shall be in accordance with the City of Encinitas Tree Preservation Policy.
5. No chemical herbicides are to be used within 100 ft. of a tree's dripline.
6. Do not nail grade stakes or anything else to trees.
7. Encroachment from paving or structures within the dripline of a tree shall be permitted
only with written authorization from the City Arborist.
8. Do not strip topsoil around trees. Any vegetation to be removed should be removed by
cutting at ground level rather than pulling out by equipment.
9. Use a pneumatic drill to excavate under woody roots larger than 2" in diameter. Do not
cut any root larger than 2" diameter. If roots must be severed, cuts are to be made by a
Certified Arborist and soil backfilled immediately.
Typical Work Procedures
These procedures have been developed to minimize the impacts to each tree and protect them
from unscheduled damage. All work around any existing tree to remain and to be protected shall
follow these work procedures.
1. All work within a tree's root zone shall follow this Manual.
2. The extent of all work affecting any protected tree shall be staked by field survey and
reviewed with the Parks and Recreation Arborist prior to construction.
3. A Parks and Recreation Arborist shall approve any pruning of protected trees prior to the
start of construction.
4. Hand dig the vertical trench at the final cut line and to the final grade; cleanly cut roots
behind torn ends. There is no need to apply any kind of pruning seal, since roots will
form their own internal barriers to decay.
APPENDIX 3.16 PAGE 3 -101
5. Type I, II, or III tree protection fencing shall be constructed at the limit of approved work
to protect the trees from unauthorized damage. It shall remain in place until landscape
work commences.
6. No further work within the root zone shall be done beyond that which was approved
without obtaining written approval form the City Arborist, prior to proceeding.
7. The area within the chain link fence shall not be used for material or equipment storage, or
parking during construction.
8. During construction, the impacted trees should be closely monitored for symptoms of
shock. The contractor should be prepared to provide temporary water to irrigate and if
needed, wash dust from foliage. Irrigation should wet the top 2 -3 feet of soil to replicate
similar volumes and normal seasonal distribution. Contact the City Arborist if a decline
in tree condition is noted.
9. Contact (760)633 -27470 for any general questions regarding trees in parks.
Damages
If a tree designated to remain is removed or irreversibly damaged as determined by the
City Arborist, a contractor may be required to install a replacement tree matching in size, quality
and variety, using an contractor designated by the City Arborist. If an acceptable replacement
tree is not available, the contractor may be required to pay damages to the City for the value of
the damaged tree in accordance with the guidelines set forth in the Guide for Plant Appraisal, 9th
Edition, using the Trunk Formula Method.
Implementation
Please direct questions about construction adjacent to Heritage trees to the City Arborist.

Appendix D
HOW TO PREVENT DAMAGE TO TREES DURING CONSTRUCTION
Introduction
Land development and capital improvement projects are a complex process and even more
challenging when trees are involved. Construction is one of the greatest causes of tree decline
and death in urban areas. The long -term goal of the City of Encinitas is urban forest
sustainability. The City seeks to maintain social, recreational, ecological and economic functions
of trees and their benefits over time. Stewardship of naturally occurring and planted trees is a
central element in forest sustainability. Concerns integral to a sustainable urban forest are tree
health and structure, preservation during development and redevelopment, species and site
selection, quality of planting stock, standards of performance, maintenance practices in our
parks, and recycling.
Tree protection should not begin subsequent to construction. If preservation measures are
delayed or ignored until construction begins, the trees may be destined to fail. Since in most
cases construction affects to trees cannot be completely eliminated, the goal for planners and
designers is to keep injury to trees to a minimum and allow building projects to proceed at the
same time. Successful tree preservation occurs when designers, construction personnel, and
project managers are committed to tree preservation. All members of the project team must be
familiar with the rudimentary aspects of tree growth and development in order to understand the
relationship between tree survival and construction practices.
There are many myths about how trees grow. For example, above ground parts of trees is not a
"mirror" of what lies below ground. In actuality, typically four to eleven large roots radiate from
the base of a tree's trunk. These "buttress" roots extend from the root crown and sometimes are
visible when the trunk flares away from the root crown or collar. These large roots decrease in
taper rapidly and branch repeatedly so that at distances of ten feet or more from the trunk they
are about '' /z inch in diameter or smaller. These roots grow horizontally through the soil and
depending on the tree can extend 40 feet or more beyond the branch tips. These smaller roots are
primarily responsible for water and mineral absorption. There can be hundreds of roots in a cubic
inch of soil thus any removal of soil or root severance forces a tree to compromise its
physiological processes to sustain the loss. All trees cannot and should not be preserved. Trees
that are structurally unstable, in poor health, or unable to survive effects of construction become
a liability to the project and should be removed. A realistic tree preservation program
acknowledges that conflicts between trees and development may sometimes result in the removal
of some trees and recognizes the detrimental effect to the project and community when trees die
after construction is completed.
Successful tree preservation occurs when construction impacts to trees are minimized or avoided
altogether. The challenge is to determine when impacts will be too severe for the tree to survive,
not only in the short term, but also in the long term. There are no quantitative methods to
calculate this critical level. Determining the optimum tree protection zone provides a guideline,
PAGE 3 -104 APPENDIX 3.16
CITY OF ENCINITAS ENGINEERING DESIGN MANUAL - 2009
although trees often survive and flourish with smaller protection areas. The following are the
three guiding principles for tree preservation:
• The acknowledgement that not all trees are in excellent health or have good
structural stability.
• Tree preservation cannot be the responsibility of the City of Encinitas staff alone. Each
development participant must understand that his or her activities and decisions influence
the success of tree preservation efforts.
• The ability of a Certified Arborist to cure construction injury is very limited, so the focus
of preservation efforts is the prevention of damage.
Instructions
An arborist should be called in as a consultant to the construction site before any work is started.
The arborist will recommend the removal of trees that are not likely to survive construction
activities regardless of the scope of work. In general, the contractor is responsible for preventing
trees from damage. The construction and maintenance staff must make the best effort to avoid
unnecessary activities within the dripline of trees.
• Fences - Construction fences shall be erected around trees that are to remain. The fences should
be placed as far from the trunk as possible in order to protect the above ground portion of the
trees as well as the root system.
• Storing and Piling - Leaning objects against tree trunks and piling soil over the root zone is
prohibited.
• Pruning - Pruning for vertical clearance of buildings, traffic, and construction equipment shall
be performed by an arborist only, and not by construction or
maintenance personnel.
• Compaction - Driving equipment and walking within the dripline causes soil
compaction and is a serious cause of tree decline and death, and usually manifests long after
construction is complete. Fences around trees reduce unnecessary traffic. If traffic cannot be
avoided, it is recommended to spread a 6 -12 inch thick layer of mulch to reduce compaction. As
an added precaution, placing large plywood sheets over the mulch can disperse weight.
• Excavation - Excavation causes major damage to trees. Digging and trenching should be
planned ahead to minimize the root loss. When roots must be severed, clean cuts shall be made
and sealed by an arborist. The soil shall then be backfilled immediately to minimize drying of the
roots.
• Tree Maintenance - Abruptly terminating regular tree maintenance is another cause for tree
decline. Provide supplemental irrigation to replicate similar volumes and normal season
distribution.

GRADING GUIDELINES
�- -'� PERMITS AND ENVIRONMENTAL REVIEW
Section I: When a Grading Permit is NOT Required:
Pursuant to Section 23.24.090 of the City's Grading Ordinance, an applicant is not
required to obtain a grading permit if all of the following criteria are met:
A. The land area which is disturbed or filled is 10,000 square feet or less.
B. The effected natural and finished slopes are less than 25% gradient and the
grading could not result in an adverse condition to existing or proposed
structures, neighboring properties, public rights -of -way or storm water
pollution control devices. (Ord. 2008 -03)
C. The volume of soil or earth materials stored, graded, moved, replaced,
imported, exported or otherwise disturbed is 50 cubic yards or less. (Ord.
2008 -03)
D. Rainwater runoff is diverted, either during or after construction, from an area
smaller than 5,000 square feet.
E. An impervious surface, if any, of less than 5,000 square feet is created.
F. No drainageway is blocked or has its stormwater carrying capacities or
characteristics modified.
G. The activity does not take place on an inland or coastal bluff, within 100 feet
by horizontal measurement from the top of an inland or coastal bluff, the
bank of a watercourse, the mean high water -mark (line of vegetation) of a
body of water or within the wetlands associated with a watercourse or water
body, whichever distance is greater. (Ord. 2008 -03)
H. Retaining wall constructed six feet or lower measured from the top of the
wall to the lowest adjacent grade. (Ord. 2008 -03)
I. Grading is proposed for a development that is not classified as a priority
project for post construction storm water pollution control. (Ord. 2008 -03)
J. No clearing and grubbing of vegetation and no disturbance of land within an
environmentally sensitive area are proposed. (Ord. 2008 -03)
A grading permit is not required for excavation which is strictly limited to that below
the finished grade of a building (for basements or footings), below a retaining wall for
footings, or excavation for a swimming pool, septic tank, or similar below - ground
structure authorized by a valid building permit. The use of such excavated material as
fill, however, may require a grading permit, as determined by criteria above.
Section II: Environmental Review of Grading Plan Applications
The Planning and Building Department shall determine if environmental review is
required prior to submitting the grading plans to the Engineering Services
Department for processing. Grading clans will not be accented by Engineering
Services unless environmental clearance has been obtained from Planning and
Building.
Section 23.24.110 of the City's Grading Ordinance provides that all grading
permit applications shall be reviewed by the Planning and Building Department,
whereupon a determination will be made as to whether environmental review will
be required. If such review is required, the developer must complete and submit
an application for an Environmental Initial Study (EIS) to the Planning and Building
Department along with the associated deposit amount. The Planning and Building
Department shall than determine the appropriate form of environmental review
given the project particulars, i.e., Negative Declaration or Environmental Impact
Report. Whichever form environmental review takes, all documentation shall be
prepared in accordance with the California Environmental Quality Act (CEQA) as
well as the City's CEQA Implementation Guidelines and environmental processing
procedures. The environmental review process shall be completed pursuant to
CEQA prior to issuance of the grading permit.
Section III: California Coastal Commission Review
No grading permit shall be issued for a project or development within the
California Coastal Zone without evidence of an approved Coastal Act permit or a
certificate of exemption from Coastal Act requirements granted by the Coastal
Commission. Regardless of City requirements for grading permits, any grading
activity in the Coastal Zone is subject to review for conformance with the Coastal
Act. Therefore, any person proposing to grade within the Coastal Zone should
contact the California Coastal Commission as to permitting requirements.
Section IV: Grading Permit Application and Plans
A: Preparation of the Grading Plan
Grading plans are to be prepared on D -size (24" x 36 ") sheets with the City title
