FINANCIAL STATEMENT: No financial impact.
BACKGROUND:
The Heritage Tree Ordinance, Chapter 5.60 of the Dublin Municipal Code, was adopted by the City
Council in December of 1999, after a public hearing. The City Council found that the preservation of
Heritage Trees was beneficial to the health and welfare of citizens in the City of Dublin in order to
enhance the scenic beauty, increase property values, encourage quality development, prevent soil erosion,
protect against flood hazards and the risk of landslides, counteract pollution in the air and maintain the
climatic balance within the city. -
On December 12, 2000, the Planning Commission approved a Heritage Tree Protection Plan and related
pruning as part of the approval of the Brittany LaneBlack Mountain Development (PA 00-009). The Tree
Protection Plan was a requirement of the Heritage Tree Ordinance, and the pruning was a requirement of
the City of Dublin's Wildfire Management Plan. The following week, on December 19, 2000, City
Council directed Staff to provide a detailed definition of terms currently within the Heritage Tree
Ordinance. The City Council also questioned Staff regarding ambiguities in the text of the Ordinance.
The Brittany LaneBlack Mountain project was appealed to City Council on December 21, 2000. Several
of the grounds of the appeal were the alleged inadequacies of the Heritage Tree Protection Plan and the
severity of the proposed pruning. The appeal was scheduled for public hearing for the January 16, 2001
meeting of City Council. On January 16, 2001, City Council continued the public hearing and directed

G:\PA#12002\02-0131ccsrapri12002.DOC
that the project be redesigned to minimize impacts to the heritage trees on site. The City Council also
directed Staff to look at ways to modify the Wildfire Management Plan to take into consideration Heritage
Trees.
On February. 20, 2001, City Council approved an amended Wildfire Management Plan. The amended plan
was applicable citywide, it designated certain trees as "Fire Resistive Heritage Trees" and it allowed
special pruning regulation of these trees when in the proximity of residential structures. At the same
meeting City Council approved the redesigned Brittany LaneBlack Mountain project, which incorporated
elements of the amended Wildfire Management Plan.
On March 5, 2002, City Council approved additional amendments to the Wildfire Management Plan
(included in this report as Attachment 3).
ANALYSIS:
The purpose of the amendment before the Council tonight is: to provide the clarification requested by City
Council on December 19, 2000 and during the Brittany Lane/Black Mountain appeal; to make the
Heritage Tree Ordinance consistent with the amended Wildfire Management Plan; and to increase the
penalty for illegal destruction of a Heritage Tree. The amendment consists of both substantive changes to
the text and general changes to word choices, in the following categories:
- General Text Changes
- Definitions
- Tree Protection Plan Requirements
- Utilities
- Penalty for Illegal Destruction
General Text Changes:
The general changes to word choices and phrasing are underlined and striked-out in the attached Draft
Amended Heritage Tree Ordinance with Revisions Marked (Attachment 2). The changes are found
throughout the text and are too numerous to describe in detail. The City Attorney and Staff propose the
changes to make the text of the Ordinance more clear and direct.
New Definitions:
Under section 5.60.40, the original Heritage Tree Ordinance did not include definitions for "drip line,"
"effectively remove," "protect," or "remove or removal." Definitions were added to make application and
enforcement of the ordinance more straightforward. "Drip line" is a term used in the Wildfire
Management Plan, as well as in the text of the Heritage Tree Ordinance. The definitions for "effectively
remove," "protect," and "remove or removal" make it clear what types of activities are subject to the
terms of the Heritage Tree Ordinance. "Protect" is defined to safeguard Heritage Trees so that they will
likely survive and continue to grow normally in a healthy condition. The Brittany LaneBlack Mountain
project had raised questions regarding the word "protect" and whether it was less of a safeguard than
"preserve." The remaining new definitions, "effectively remove" and "remove or removal," would
specify actions that harm a Heritage Tree as infractions under the Heritage Tree Ordinance.
2
The Amended Ordinance would include the following new definitions:
1. "Drip line" means a line. drawn on the ground around a tree directly under its outmost branch tips
and which identifies that location where rainwater tends to drop from the tree.
2. "Effectively remove" includes, but is not limited to, any extreme pruning that is not consistent
with standard arboriculture practices for a healthy Heritage Tree and that results in the tree's
permanent disfigurement, destruction; or removal ordered by the City pursuant to subdivision
(b)(2) of section 5.60.50.
3. "Protect" means. the protection of an existing tree from damage and stress such that the tree is
likely to survive and continue to grow normally in a healthy condition, through measures that
avoid or minimize damage to branches, canopy, trunk, and roots of the tree. Such measures may
include but are not limited to, installation of tree protective fencing, mulching and watering of
roots, supervision of work by an arborist, installation of aeration or drainage systems, root pruning,
and use ofnon-destructive excavation techniques.
4. "Remove or removal" means cutting a tree to the ground, extraction of a tree, or killing a tree by
spraying, girdling, or any other means...
Tree Protection Plan Requirements:
Under section 5.60.80, the original Ordinance stated, "Heritage Trees required to be retained pursuant to
this chapter or by an approved development plan, zoning permit, use permit, site development review or
subdivision map shall be protected during demolition, grading and construction operations." The amended
Ordinance specifies that a procedure called a "tree protection plan" shall be used to protect heritage trees
during construction. The amended version references section 5.60.90 of the Ordinance, which outlines the
components of such a plan.
All applicants for demolition, grading, or building permits on property containing one or more
Heritage Trees shall prepare a tree protection plan pursuant to Section 5.60.90.
Under section 5.60.90 of the original Ordinance, a certified arborist must prepare a tree protection plan. In
the amended Ordinance, the following proposed addition to the text would explain the components of the
tree protection plan:
The plan shall ensure that the tree, including its root system, is adequately protected from potential
harm during demolition, grading and construction that could cause damage to the Heritage Tree.
Such harm may include excavation and trenching, construction and chemical materials storage,
stormwater runoff and erosion, and soil compaction.
Utilities:
Under section 5.60.110, the original Ordinance requires any public utility to receive permission from the
Community Development Director before performing any work that might injure a Heritage Tree. The
amended Ordinance would add a requirement that the Community Development Director shall provide a
copy of the Ordinance to all utility companies.
The Director shall provide all water, sewer, electrical and gas utilities operating within the City
with a copy of this ordinance.
3
Fees:
Finally, under section 5.60.120, the amended Ordinance increases the penalty for illegally removing a
Heritage Tree to twice the appraised value of the tree, in addition to the City's costs. for the appraisal. The
adequacy of the penalty was an issue in the Brittany Lane/Black Mountain appeal. City Council indicated
that Staff should examine an increase in the penalty as a deterrent to persons who may damage or illegally
remove a Heritage Tree. The fine is comparable to fines in other cities in the Tri-Valley area.
Any person who unlawfully removes, destroys or damages a Heritage Tree shall pay a civil penalty
equal to twice the amount of the appraised value of the tree. Acity-selected arborist shall estimate
the replacement value of the lost tree(s) in accordance with industry standards. The penalty shall
include the. City's costs. incurred in performing the appraisal.
Environmental Review:
Community Development Staff have determined that the Amended Heritage Tree Ordinance is
categorically exempt under Section 15307, "Actions. by Regulatory Agencies for Protection of Natural
Resources," under CEQA because the amendment is an action taken by a regulatory agency as authorized
by state law to assure the maintenance, restoration, or enhancement of a natural resource where the
regulatory process involves procedures for protection of the environment.
CONCLUSION:
Staff believes that the Amended Heritage Tree Ordinance will implement City Council objectives and will
both protect Heritage Trees and facilitate development of sites containing Heritage Trees. The amendment
clarifies procedures and requirements under the Heritage Tree Ordinance and makes the Ordinance
consistent with approved changes to the Dublin Wildfire Management Plan. In addition, the amendment
will establish a stronger deterrent to person's whose development program may damage a Heritage Tree.
RECOMMENDATION:
Staff recommends that the City Council conduct a public hearing; deliberate; waive the reading and
introduce an Ordinance (Attachment 1) approving the Amended Heritage Tree Ordinance; and schedule
the second reading of the Ordinance for Apri130, 2002.

The purpose of this plan is to reduce the risk of open land wildfire to the lowest practical level
consistent with reasonable protection of wildlife habitat and other open space values-
Authori
Adopted by Dublin City Council Resolution 84-96 dated July 9, 1996. Amended by Resolution
24-01, March 20, 2001, Revised by Resolution -02, January 2002.
Requirements
This plan will satisfy the requirements as follows:
Implementation of the Wildfire Management Plan is the responsibility of the City of Dublin.
Vegetation and habitat (in open space) will only change-as a result of natural forces. or other
actions (weed abatement), since this. plan does not impose requirements into the open space.
This plan provides for the development of a Fire Buffer Zone between open space/undeveloped
lands and developed properties; therefore, no additional brush control measures are .required
where this plan is utilized.
Vegetation- growth within- areas affected by this plan will be monitored in two ways. First, all
areas will be inspected in accordance with the Fire Department's Abatement Program. Second,
whenever any building,. grading or other activity affects open space/undeveloped lands or the
Fire Buffer, reevaluation will take place.
Wildlife habitat ~ will be evaluated by the City when there is any proposed change in open
space/undeveloped lands.
Applicability
This Wildfire Management Plan applies to all new development within the City of Dublin.

FINDINGS OF FACT A1~TD NEED FOR
C:`HANGES OR MODIFICATIONS TO THE
STATE BUILDINGS STANDARDS CODE
BECAUSE OF LOCAL CONDITIONS
CHANGES OR MODIFICATIONS: Pursuant to Section 17958 of the State of
California Health and Safety Code, the City Council of the City of Dublin, in its
resolution amending the 'Wildfire 1Vlanagement Plan of 1996, changes or modifies certain
provisions of ,the State- Building Standards Code, as it pertains to the regulation of
buildings used for human habitation.. A copy of such text of changes or modifications is
included in the City Council resolution attached as Attachment 2.
FINDINGS: Pursuant to Sections 17958.5 and .17958.7(x) of the State of California
Health and Safety Code, the City Council of the City of Dublin has determined the
attached changes or modifications are needed,- and are .reasonably necessary .because of
local climatic, geographic,- and topographic conditions. A copy of the City Council
resolution making such a deternvnation is attached as Attachment 1.
LOCAL CONDITIONS: Local conditions have an adverse effect on the prevention of
(I) major fire loss, (2) the potential for life and property loss; making necessary changes
or modifications in the Uniform Fire Code and the State Building Standards Code, in
order to provide a reasonable degree of property security and fire and life safety in the
City of Dublin. ~
Within the areas of the City exist approximately 12.20. square miles of land; with a
population of 32,500. Within thin area of drastically varied terrain, are developed
residential urban areas, .which interface with sparsely populated rural areas and rolling
,hills. Because of the climatic conditions, which exist in the City, and the nature of the
topography and geography of the City, these Findings of Fact. listed below shall be
submitted to the California Building Standards Commission.
1• CLIMATIC -
A. Precipitation. Precipitation ranges from 8.6 to 21.2 inches per year, with
an average. of approximately 14.52 inches per year. Approximately 85%
falls during the months November through April, and 15% from May
through October. This area experienced a major drought and it is possible
more droughts will occur in the future.
B. Relative Humidity. Humidity generally .ranges from 60% .during the
daytime,.. to 80% at night. It drops to 20% during the summer months and
occasionally lower.
ATTACIIMENT 3
~ ~ yl
C. Temperature. Temperatures have been recorded as high as 108 degrees f.
During the summer months, the .City can experience temperatures such as
that for extended periods of time. .
D. Winds. The prevailing winds are from the Northwest; however, winds are
experienced from virtually every direction at one time or another. Wind
. speed varies from a light breeze of 5 mph to I S mph. In the summer
months, the wind may gust from 7-mph to 30 mph. Additionally the fog
may reach the City, which will provide some cooling effect. Regardless of
the cooling effect of the fog on the Western side of the hills, the City is
prone to periods of Westerly, Northwesterly winds, and "Fohen type"
winds that have. the same effect as the "Santa Ana" winds of the South
state.
E. Summary. These local climatic conditions affect the acceleration,
intensity, and size of fires: in the community. Times of little or no rainfall,
low humidity, and high temperature create extremely hazardous
conditions. The winds in this area can have a tremendous impact upon
structure fires where buildings are built in close proximity to each other,
and fires within the Wildland Urban Interface which can threaten the
structures built in an around the brush and timber. Both of the above listed
conditions are commonly found in the City.
2. GEOGRAPHIC and TOPOGRAPHIC
A. Geographic location, Topography. The City of Dublin is located on the
eastern side of the foothills of the Oakland Range. The City is
characterized by a flat plain at the intersection of Highways 580 and 680.
To the east and west of this central area axe hilly areas that become
increasingly steeper. The flatter and more moderately sloping areas
include existing or planned urban level development. Interface between
open space wildland and urban development areas are common. Within
the hill area are numerous homes and planned developments. With the
.steep valleys and winding roadways leading to these areas, fire spread and
response time are impacted.
B. Roads and Streets. The number of vehicle miles driven in the City is
steadily increasing and efforts in traffic and roadway improvements are
being made in an attempt to ease the crush of commuters to and through
.the areas. The City is intersected by Highways 580 and 680. There is also

C• Summary. The above local geographic and topographical conditions
increase the magnitude, exposure, accessibility problems, and fire hazards
presented to the fire departments serving the City.
CONCLUSION: Local climatic, geographical, and topographical conditions impact fire
prevention and suppression efforts; the frequency, spread, acceleration, and intensity of
the fire involving buildings and wildland areas within the City of Dublin. While it is
clearly understood that the adoption of these modifications to the Code may not prevent
the incidents of fire, it is further noted that the implementation of these modifications
may serve to reduce the severity and potential of life and property due to fire.
