To accommodate an existing house that is located within 50 feet of the property line adjacent to a collector or arterial road, the roadside buffer area width shall be reduced to the width between the existing house and the property line adjacent to the collector or arterial road. iii. Multiple street frontages. For properties subject to the roadside buffers requirement along two property boundaries, the roadside buffer abutting the street with the lower classification may be reduced to 25 feet in width. For properties that abut more than two streets requiring roadside buffers or in situations where both abutting streets are of the same road classification, one roadside buffer of the full required width (50-foot or 40-foot) shall be required and all other roadside buffers may be reduced to 25 feet, provided that the full required width (50~foot or 40-foot) buffer is located where a greater number of significant trees can be incorporated into the buffer. c. Park Buffers and Buffers for Dedicated Conservation Lands. A 25-foot wide buffer shall be provided along a property line where the land adjacent to the subdivision boundary is a park or a future park in a municipal plan, or dedicated conservation land area that has been set aside for open space, wildlife habitat or public conservation purposes by deed or conservation easement. d. Landscape Perimeter. When the cluster development option is selected pursuant to BIMC 17.12.090.A.5, the following applies: i. In the R-2.9, R-2, R-1 and R-0.4 districts, a 25-foot wide landscape perimeter shall be required along the subdivision boundary; or ii. In the R-3.5 and R-4.3 districts, a 10-foot wide landscape perimeter shall be required along the subdivision boundary. e. Allowed Landscape Buffer Activities: i. Potable water wells and well houses; ii. Onsite storm water infiltration systems where the vegetated features of the buffer are not adversely impacted; iii. Ingress and egress, where the access runs approximately perpendicular to the landscape perimeter; iv. Underground utilities, where they run approximately perpendicular to the landscape perimeter, provided that disturbance is minimized and the buffer is revegetated after construction; v. Non-motorized trails; vi. Planting of vegetation; and vii. Fences, a maximum height of 6 feet. f. Landscape Buffer Requirements. i. In order to buffer the visual impact of the proposed subdivision and protect off-site views, filtered screen landscaping, pursuant to BIMC 18.85.070.B.3 and 18.85.070.C, shall be required within park buffers, buffers for dedicated conservation lands and landscape perimeter buffers where established vegetation cannot provide such screening. ii. All native shrubs and significant trees shall be retained within all landscape buffers, except that limited removal may be allowed for permitted activities located within the buffer area. iii. Required landscape buffer width may be reduced through buffer averaging in accordance with the criteria in BIMC 18.85.070, Landscape Regulations, when such Ordinance 2003-02, Effective 10-1-03 12 adjustments contribute to the neighborhood character by incorporating significant trees and native vegetation within the buffer that retain the forested character of a street and may otherwise have not been protected; incorporate a unique landscape feature; or accommodate a unique situation that allows continuation of an existing use, such as a utility or other easement providing continued use. g. Landscape buffers may be included in the required open space calculations for a subdivision as noted in Table II. Table II depicts the landscape buffer requirements for subdivisions by zoning district and denotes when the buffer may be included in the open space calculations.

Cluster Development Option. Clustering of development may be selected as an optional standard. If an applicant chooses to cluster development, the open space provisions of BIMC 17.12.092 shall not apply. Clustering shall be accomplished through the design process specified in the Flexible Lot Design Handbook; and should meet the intentions of the open space objectives, open space design guidelines and Ordinance 2003-02, Effective 10-1-03 13 prioritization of open space as provided in BIMC 17.12.092.A through C; and the following requirements shall apply: a.

In the R-3.5 and R-4.3 zoning districts the maximum home site area provided for each lot shall be 7,600 square feet and shall be depicted on the face of the plat. iii. The purpose of the homesite area is to define the maximum disturbance area for development of the primary residential dwelling, garages and accessory dwelling unit for each lot within the subdivision. iv. Other allowed uses and structures may be located within the lot and outside the homesite area, provided that all other applicable requirements of the Bainbridge Island Municipal Code are satisfied. b. Homesite clustering. i. The purpose of clustering is to facilitate the efficient use of land by reducing disturbed areas, impervious surfaces, utility extensions and roadways, while providing for the protection of priority open space features as provided in BIMC 17.12.092.C. ii. Homesites shall be clustered into cluster groupings and the efficient location of infrastructure shall be utilized to maximize open space area in a flexible lot design subdivision. iii. To facilitate clustering, homesites of two or more shall constitute a cluster grouping. iv. To promote clustering, all homesites in a cluster grouping shall adjoin or be located a maximum of 25 feet apart from another homesite in a cluster grouping, except as follows: (a). The Fire Marshal requires a greater distance for fire protection requirements; or (b). The location of existing critical areas precludes the ability to adjoin or locate a homesite within 25 feet of another homesite. B. Landscape Standards. Landscaping shall be established consistent with the requirements of BIMC 17.12.090.A.4 and Chapter 18.85 BIMC, and any other significant tree retention requirement. C. Roads and Pedestrian Access Performance Standards. The following standards apply to all subdivisions. 1. Existing roadway character shall be maintained where practical.

Open space configuration shall satisfy the following guidelines: 1. Open space should be concentrated in large, consolidated, usable areas in which the area of the open space is delineated with a low perimeter to area ratio (see example in Table III, below); 2. Open space should connect to adjacent off-site open space areas, designated greenways and/or critical areas; 3. Open space should be designed to preserve views from off-site of the subject property; 4. Open space should be designed to preserve established vegetation on ridgelines; and 5.

Table IV Prioritization of Open Space Features Priority Open Space Feature Notes (Ranking) 1 Critical Areas (as defined All critical areas and their associated in Chapter 16.20 BIMC) buffers shall be preserved. and areas contiguous with critical areas and/their buffers 2 Significant trees identified consistent with Native Forests the standards of the Landscaping Ordinance (BIMC 18.85) should be preserved. 3 Mature Vegetation on Mature vegetation found on ridgelines of Ridgelines community significance (as viewed fi-om off-site) should be preserved. 4 Pastures and Farmland Pastures, farmland and land areas currently or traditionally used in agriculture should be preserved. 5 Trails and Greenways Trails and greenways should be preserved. D. Open Space Area Requirements. 1. Required Area. The area dedicated for open space area shall be a minimum of 30% of the area of the property being subdivided, unless additional open space area is otherwise provided pursuant to section ! 7.12.092.D.4 and should be consistent with the priority open space features (Table IV above). Ordinance 2003-02, Effective 10-1-03 16 2. Fee in-lieu of open space. When an applicant cannot provide all of the required open space within a subdivision, a fee in-lieu of open space shall be paid to the city and the city will acquire open space within the designated open space zone in which the subdivision is located. This option is available only after the city adopts the fee in- lieu program and for properties that meet the application criteria and pay the fee as prescribed in the fee in-lieu of open space program. 3. In determining the open space designation requirement stated in section D. 1 above, the City has relied on the Analysis of Open Space report dated July 15, 2003 and the other reports, statutes and documents referenced in the recitals to Ordinance No. 2003-02 ("Open Space Documentation").
