IRRIGATION
Intent:
To provide temporary or permanent irrigation within new planting areas without
high soil moisture conditions.
Requirements:
Except for areas of undisturbed existing vegetation or low areas with existing
high soil moisture conditions, landscape areas shall have temporary or permanent
irrigation systems. Temporary systems may be removed after 24 months or 2
growing seasons, whichever occurs first, provided that the plantings are
established.
Areas of undisturbed existing vegetation or areas where existing site conditions
assure adequate soil moisture for growth within the required landscape area shall
have temporary irrigation systems only as required to sustain new plantings.
Areas of undisturbed existing vegetation, low areas with existing high soil
moisture conditions, or landscape areas consisting of drought-tolerant vegetation
may not require permanent irrigation systems. Permanent irrigation systems may
be permitted within all other required landscape areas, provided such systems
shall be designed with:
1) Moisture or precipitation sensors; and
2) Automatic timers set for operation during periods of minimum
evaporation and that assure adequate moisture levels; and
3) Head-to-head spacing, if sprinkler heads are proposed; and
4) Pressure regulating devices; and
5) Backflow prevention devices; and
6) Separate irrigation zones for a) turf and planting beds, and b) other
nondrought-tolerant species.
Irrigation water shall be applied with goals of avoiding runoff, low head
drainage, overspray, or other similar conditions where water flows onto adjacent
property, non-irrigated areas and impervious surfaces by:
1) Considering soil type and infiltration rates; and
2) Using proper irrigation equipment and schedules, including features
such as repeat cycles, to closely match application rates with infiltration
rates; and
3) Considering special problems posed by irrigation on slopes and in
median strips.
Landscape Requirements 42 8/30/95
Irrigation systems shall be subject to the following additional provisions:
1) Systems in landscape strips less than five feet in width shall be designed
to ensure that overspray and/or runoff does not occur by use of system
design options such as low volume emitters; and
2) Sprinkler heads with consistent application rates shall be selected for
proper area coverage, operating pressure, and adjustment capability;
and
3) Separate valves shall be used to irrigate plants with differing water
needs.
Landscape Requirements 43 8/30/95
MAINTENANCE
Maintenance of Landscaping and Significant Trees
Intent:
All new landscape plantings and significant tree(s) and tree stands to be retained
shall be maintained to preserve the Island's Forested Character.
Requirements:
All landscaping, significant trees and tree stands shall be maintained for the life
of the project.
All landscape materials, significant trees and tree stands, except within
environmentally sensitive areas or their protective buffers, shall be maintained in
a healthy growing condition.
With the exception of dead, diseased or damaged trees specifically retained to
provide wildlife habitat; other dead, diseased, damaged or stolen plantings shall
be replaced on a 1 for 1 basis within 6 months or during the next planting season
if the loss does not occur in a planting season.
Landscape areas shall be kept free of trash.
All plant material shall be managed by pruning so that plant growth does not
conflict with public utilities, restrict pedestrian or vehicular access, or creates a
traffic hazard.

Drought-Resistant Plant Material
Plant material once established can survive with little or no water other than that
from annual rainfall.
Greenways Plan/Scenic Road Corridors
These road corridors are noted for having outstanding buffers to screen the
adjacent development. As parcels are developed along these roads, it is important
to retain that buffer.
Native Vegetation
Plant species which are indigenous to the Puget Sound Region.
Perimeter Averaging
A method that allows required landscape perimeters to be reduced to a minimum
dimension and cluster plants to areas within the perimeter that provides denser
screening adjacent to structures and parking areas, and allows lesser screening in
areas where there are no structures and parking areas. Perimeter averaging is
also allowed to retain significant trees and tree stands located within the
perimeters. The total required perimeter dimension square footage must be
achieved.
Protection Zone
The zone at grade level located directly below the canopy and within the dripline.
Screen
A system of vegetation located within the perimeter landscape to provide varying
degrees of visual separation between land uses and site development.
Landscape Requirements 45 8/30/95
Significant Tree
A significant tree is:
a. Evergreen tree 10 inches in diameter or greater, measured 4 feet above
existing grade.
b. Deciduous tree 12 inches in diameter or greater, measured 4 feet above
existing grade.
c. Belongs to a unique or unusual species.
d. Is located within 25 feet of any sensitive area or within a required
sensitive area buffer.
e. Is identified as providing valuable wildlife habitat.
f. Is of historical or cultural significance.
g. Is of an old growth forest or over 100 years in age or over 48 inches in
diameter.
h. Provides energy savings through winter wind protection or summer
shading as a result of its location relative to buildings.
Tree Canopy
The total area of the tree or trees where the leaves and outermost branches
extend, also known as the "dripline".
Tree Stand
Tree stand consisting of at least 5 - 15 trees or more forming a continuous
canopy, each having a six inch diameter or greater, measured 4 feet above
existing grade.

GUIDELINE FOR SAVING TREES AND
UNDERSTORY VEGETATION
PROTECTING VEGETATION DURING
CONSTRUCTION
Provide a protection zone around the vegetation to be
saved. This zone will allow the plants to continue to
receive air, water and nutrients. The protection zone
should be larger than the dripline of the canopy or
crown of the tree (s) or understory vegetation.
A consulting Arborist certified by the International
Society of Arborculture could recommend
modifications to this guideline based upon specific
site conditions.
PREVENTION OF VEGETATION INJURY
· Do not park, store materials or construct
permanent features within the protection zone.
· Do not add or remove soil within the vegetation
protection zone.
· Save groups or stands of trees when possible to
lessen the exposure of single trees to wind damage.
Consult with an Arborist certified by the International
Society of Arborculture i.f trenching or tunneling for
utilities within the vegetation protection zone.
PLANTING NEW VEGETATION
NOTE UTILITY LOCATIONS
Do not plant large trees beneath overhead utility lines
that achieve a maximum height greater than 25-30
feet. Contact the utility company to confirm tree
species selection.
Also note the locations of traffic signs, fire hydrants,
sewer and water lines and other underground utilities
such as natural gas and telephone cable to avoid
conflicts.
TREE AND UNDERSTORY REQUIREMENTS
Consider the plant's ultimate special needs. Avoid
conflicts with tree roots near sidewalks, streets and
driveways.
Plant vegetation in locations where there is adequate
drainage.
Plant the right vegetation in the right environmental
location. Use native and drought tolerant varieties
where appropriate, to promote water conservation, to
enhance the Island's natural character and provide
additional wildlife habitat.

TREES AND UNDERSTORY VEGETATION
PROVIDE ENERGY CONSERVATION BENEFITS
Vegetation provides wind breaks in the winter and
offer shade in the summer for more efficient home
heating and cooling.
SOME REASONS TO PRESERVE THE
ISLAND'S FORESTED CHARACTER
TREES AND THE ASSOCIATED UNDERSTORY
Vegetation is a major contributor to the Island's
natural landscape character.
TREES AND UNDERSTORY VEGETATION
INCREASE PROPERTY VALUES
Surveys indicate real estate surrounded by vegetation
increases in value up to 20%.
TREES AND UNDERSTORY VEGETATION
PROVIDE WILDLIFE HABITAT
Vegetation provides special conditions and habitat for
birds and animals.
TREES AND UNDERSTORY VEGETATION
CLEAN THE AIR
Vegetation absorbs CO2 and provides oxygen into the
atmosphere. It removes pollutants from the air such
as dirt, fumes, pollen, smoke, dust and odors.
TREES AND UNDERSTORY VEGETATION
PROVIDE AESTHETIC SCREENING
Vegetation provides visual separation between
properties and hides undesirable views. It also flames
and directs views to aesthetically pleasing landscapes.

STATISTICS I
The City's Landscape Ordinance applies to only 27% of
the property on the Island. This property does not
include single family residential lots. With the assistance
of the single family property owners, there is a potential
to preserve the Island's Natural Character.
The Bainbridge Island Community Survey conducted in
1992 states: "Most respondents (77 percenO think of Bainbridge
Island as having a rural character. Foresled lands are perceived
to contribute most to this rural character."
