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. ~dl-a{eas-shall-be_mainta~nTn'6d-in-a~etatively wced-frcc c~ Landscape Requirements 44 8/30/95 DEFINITIONS Caliper A measurement used for deciduous trees. Caliper of a tree trunk shall be taken 6 inches above the ground up to and including 4-inch caliper size, and 12 inches above the ground for larger tree sizes. 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.

City of Bainbridge Island, Final Non-Project EIS Draft Compre- hensive Plan, 1994 The Bainbridge Island Community Values Survey, 1992 TREES AND UNDERSTORY VEGETATION REDUCE SOIL EROSION A Forest Service survey determined surface runoff from forested areas is significantly less than that from developed areas. Vegetation root systems intercept rainfall and reduce runoff by holding soil particles in place. 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. Prepared by: NOTES Hough Beck & Baird Inc. Landscape Architects September, 1995 City of Bainbridge Island Informational Handout Preserving the Island's Natural Character in Residential Open Space Areas a landscape guide for single family residential lots INTRODUCTION ~ urf~ I Com ity ion nco the The Island's %~~d of r tia preservation e located outside Winslo~r~~ale Service Center Areas to maintain he n dscape character. This character can be d by preserving the Island's natural m ' lorested , open space, meadows and wildlife. 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." A~AC~E~ 3
