WHEREAS, the Environmentally Sensitive Areas Committee, comprised of several Bainbridge Island residents and representing a broad range of interests, held more than 20 committee meetings to prepare a draft Environmentally Sensitive Areas Proposed Ordinance, and presented it to the public for review and comment at two Town meetings held on August 14 and 21, 1991; and WHEREAS, to prepare the proposed ordinance, the Environmentally Sensitive Areas Committee, reviewed and considered environmentally sensitive areas ordinances of other cities and the Model Wetlands Ordinance prepared by the Department of Ecology; and WHEREAS, the Environmentally Sensitive Areas Committee was not compelled or required by the Department of Ecology or any other agency to use the Model Wetlands Ordinance prepared by the Department of Ecology or any other document to prepare the proposed ordinance; and WHEREAS, on October 24, 1991, the Bainbridge Island Planning Agency conducted a public hearing on the proposed ordinance; and WHEREAS, following the hearing, the Planning Agency reviewed the proposed ordinance, directed revisions to be made and recommended approval; and WHEREAS, by motion regularly passed, the Council scheduled a public hearing on the proposed ordinance for January 8, 1992, and gave notice to the public pursuant to law; and WHEREAS, the public hearing was held as scheduled on January 8, 1992, to hear proponents and opponents, and consider the Planning Agency's proposed ordinance on environmentally sensitive areas; and CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Page 3 February 20, 1992 WHEREAS, the City Council has not been compelled or required by the Department of Ecology or any other agency to use the Model Wetlands Ordinance prepared by the Department of Ecology to prepare an environmentally sensitive areas ordinance; and WHEREAS, pursuant to Article 11, Section 11 of the State Constitution, RCW 35A.11.020, RCW 35A.63.100, RCW Chapter 36.70A (Growth Management Act) and the City's Comprehensive Plan, the City Council desires to pass an environmentally sensitive areas ordinance to designate, protect and conserve environmentally sensitive areas; now, therefore, THE CITY COUNCIL OF THE CITY OF BAINBRIDGE ISLAND, WASHINGTON, DO ORDAIN AS FOLLOWS: Section 1. There is added to the Bainbridge Island Municipal Code a new Chapter 16; to be entitled "Environmentally Sensitive Areas" and to read as follows: 16.20.010 Findings. The City Council finds that critical areas and their protective buffers, and natural resource lands, constitute Environmentally Sensitive Areas (ESAs) that are of special concern to the City. The Bainbridge Island Subarea Plan and the City's policies in regard to the natural systems and enviromnent of Bainbridge Island, as well as the Washington Growth Management Act (RCW Chapter 36.70) require that ESAs and natural resources of Bainbridge Island are to be protected by establishing minionurn interim standards for the impact of development of properties which contain or adjoin ESAs. It is the intent of this chapter to protect the public health, safety, and welfare by: A. Avoiding the impact; B. Minimizing or limiting the degree or magnitude of the action and its implementation, by using appropriate technology, or by taking affirmative steps to avoid or reduce impacts; C. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment; D. Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; E. Compensating/br unavoidable impacts by replacing, enhancing or providing substitute resources or environments; F. Reducing the potential for personal injury, loss of life or property damage due to flooding, erosion, landslides, seismic events, or soil subsidence; G. Protecting against publicly financed expenditures due to the misuse of ESAs which cause: Unnecessary maintenance and replacement of public facilities; Public funding of mitigation for avoidable impacts; Cost tbr public emergency rescue and relief operations where the causes are avoidable; or Degradation of the natural environment; CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Page 1 February 20, 1992 I.

A. Classification: Bainbridge Island is the recharge area for the island aquifers. Bainbridge Island is dependent upon its aquifers as the sole and essential source for drinking water. 1. The island aquifers are vulnerable to pollution that has the potential to create a significant public health hazard. High vulnerability is indicative of land uses which produce contaminants that may degrade groundwater and low vulnerability is indicative of land uses which will not. 2. Susceptibility to pollution is a function of depth of groundwater, permeability of soils, soil types, presence of potential source of contamination and any other relevant factors. 3. Soil types that transt`er water to the aquifer are rated in terms of infiltration rate. Soil types with the high infiltration rates are associated with areas of high aquifer recharge. The rates and soil types are defined by the United States Department of Agriculture, Soil Conservation Service, in the Soil Survey of Kitsap County. Additionally, high recharge potential areas are illustrated on the Kitsap County Groundwater Management Plan April, 1991, Grant No. 1 Background Data Collection and Management Issues, Vol I & II maps and Kitsap-Bremerton Health Department maps. Standards: Standards tbr development shall be in accordance with the provisions below and the requirements of the underlying zone. 1. High Aqt!ifer Recharge Areas a. A hydrogeologist report will be required on sites that have been identified as having soil types with high infiltration rates, or having high aquifer recharge or infiltration potential. The report will address the impact the proposed land use will have on both the quality and quantity of the water transmitted to the aquifer. The report will recommend mitigation for impacts that have the potential to decrease quantity or quality of water transmitted to the aquifer. The report shall also address the types of pesticides, herbicides, and fertilizers that can safely be used tbr the care of landscaping proposed by the applicant. b. Where on-site sewage treatment is required in a high recharge area, the applicant will design the drainfield to have no less than three feet of vertical separation between the leaching field and water table. If a hydrogeologist report recommends, or Kitsap Bremerton Health Department official requires, a more advanced technology or design, the applicant shall include that technology in the design. c. Applications for land uses with underground storage of petroleum products and hazardous substances shall be prohibited in areas of high aquifer recharge. 2. Medium and Low Aquifer Recharge Areas Page 14 February 20, 1992 CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 On-site sewage treatment shall be designed according to best: available technology as required by local health department standards.

That the inability to derive reasonable economic use of the property is not the result of actions by the applicant in segregating or dividing the property and creating the undevelopable condition after the effective date of this chapter. If, through the Conditional Use Permit process it is found that alteration of a wetland and/or stream or buffer is necessary and unavoidable, the approval decision shall set forth in writing with findings with respect to each of the items listed in this subsection. Determination of Regulatory Wetland Boundary. The exact location of the wetland boundary shall be determined by the applicant through the performance of a field investigation applying the wetland definition provided in this chapter. A wetlands biologist approved by the City shall perform wetland delineations using the "Federal Manual for Identifying and Delineating Jurisdictional Wetlands (1989 version)" and evaluate impacts of the proposed project. The applicant is required to show the location of the wetland boundary on a scaled drawing as a part of the permit application. The Director, when requested by the applicant, ~nay waive the delineation of boundary requirement for the applicant and, in lieu of delineation by the applicant, perform the delineation. The Director shall consult with wetland biologists as needed to perform the delineation. The applicant will be charged for the costs incurred, including City staff time. Where the Director performs a wetland delineation at the request of the applicant, such delineation shall be considered a final determination. Where the applicant has provided a delineation of the wetland boundary, the Director shall verify tile accuracy of, and may render adjustments to, tile boundary delineation. In the event the adjusted boundary delineation is contested by the applicant, the Director shall, at the applicant's expense, obtain a wetland biologist to render a final delineation. Compensating for Wetland and/or Stream Impacts. As a condition of any permit allowing alteration of regulated wetland and/or streams and/or buffers, or as an enforcement action, the Director shall require that the applicant engage in the restoration, creation or enhancement of wetlands and streams and their buffers in order to offset the impacts resulting from the applicant's or violator's actions. The applicant shall develop a plan that provides for land acqui sition, construction, maintenance and monitoring of replacement wetland and/or stream that recreate as nearly as possible the original in terms of acreage, function, geographic location and setting, and that are larger than the original. The overall goal of any wetland compensatory project shall be no net loss of wetlands function and acreage and to strive for a net resource gain in wetlands over present conditions. Compensation slnall be completed prior to wetland and/or stream destruction, where possible. Compensatory mitigation shall follow an approved mitigation plan as required by this Chapter, and shall meet the following minimum performance standards: Page 24 February 20, 1992 CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Given the need for expertise and monitoring, compensatory projects; may be permitted only when the Director finds that the compensation project is associated with an activity or development otherwise permitted and that the restored, created, or enhanced wetland will perform the same functions and values as the wetland it replaces. Additionally, the applicant shall: C, Demonstrate sufficient scientific expertise, supervisory capability, and financial resources to carry out the project; Demonstrate the capability for monitoring the site and to make corrections during this period if the project fails to meet projected goals and plans; and Protect and manage or provide for the protection and management of the compensation area to avoid further development or degradation and to provide for long-term persistence of the compensation area. Wetlands and Streams Restoration and Creation. a. Any person who alters regulated wetlands or streams shall restore or create equivalent areas or greater areas than those altered in order to compensate for losses. Where feasible, restored or created wetlands and streams shall be a higher category than the altered wetland or stream. Compensation areas shall be determined according to ~nction, acreage, type, location, time factors, ability to be self sustaining and projected success. Functions and values shall be calculated using the best professional judgement of a wetlands biologist, or in the case of streams a stream scientist, using the best available techniques. Multiple compensation projects may be proposed for one project in order to best achieve the goal of no net loss. Acreage replacement ratio. The following ratios apply to creation or restoration which is in-kind, onsite, timed prior to or concurrent with alteration, and has a high probability of success. These ratios do not apply to remedial actions resulting from illegal alterations. The first number specifies the replacement acreage of wetlands and the second specifies the acreage of wetlands altered. Category I 6:1 Category II or Ill Forested 3: 1 Scrub-shrub 2:1 Emergent 1.50:1 CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Page 25 February 20, 1992 o Category IV 1.25: 1 ii. 111. Increased Replacement Ratio. The Director may increase the ratios under the following circumstances: (a) Uncertainty as to the probable success of the proposed restoration or creation; (b) Significant period of time between destruction and replication of wetland functions; (c) projected losses in functional value; or (d) offsite compensation. Decreased Replacement Ratio. The Director may decrease these ratios when there are findings of special studies coordinated with agencies with expertise which demonstrate that no net loss of wetland function or value is attained under the decreased ratio. In all cases, a minimum acreage replacement ratio of 1:1 shall be required. Wetlands Enhancement. a. Any applicant proposing to alter wetlands may propose to enhance existing significantly degraded wetlands in order to compensate for wetland losses. An applicant proposing to enhance wetlands shall identify how enhancement conforms with the overall goals and requirements of this ordinance. A wetlands enhancement compensation project shall be determined pursuant to this Section provided that enhancement for one function and value will not degrade another function or value and that acreage replacement ratios shall be doubled to recognize existing functional values and, provided further, that category I wetlands shall not be enhanced. Wetland Type. In-kind compensation shall be provided except where the applicant can demonstrate that: a. The wetland system is already significantly degraded and out-of-kind replacement will result in a wetland with greater ~nctions and values; b. Scientific problems such as exotic vegetation and changes in watershed hydrology make implementation of in-kind compensation impossible; c. Out-of-kind replacement will best meet identified regional goals (eg., replacement of historically diminished wetland types); and d. Where out-of kind replacement is accepted, greater acreage replacement ratios may be required to compensate for lost functions and values. Page 26 February 20, 1992 CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Location. a. On-site compensation shall be provided except where the applicant can demonstrate that: i. The hydrology and ecosystem of the original wetland and those who benefit from the hydrology and ecosystem will not be substantially damaged by the onsite loss; and ii. Onsite compensation is not scientifically feasible due to problems with hydrology, soils, waves, or other factors; iii. Compensation is not practical due to potentially adverse impact from stirrounding land uses; iv. Existing functions and values at the site of the proposed restoration are significantly greater than lost wetland ~mctional values; or v. That established regional goals for flood storage, flood conveyance, habitat or other wetland functions have been established and strongly justify location of compensatory measures at another site. Offsite compensation shall occur within the same watershed as the wetland loss occurred, provided that category IV wetlands may be replaced outside of the watershed when there is no reasonable alternative. c. In selecting compensation sites, an applicant shall pursue siting in the tollowing order of preference: i. Upland sites which were formerly wetlands; ii. Idled tipland sites generally having bare ground or vegetative cover consisting primarily of exotic introduced species, weeds, or emergent vegetation; or iii. Other disturbed upland. Timing. Where feasible, compensatory projects shall be completed prior to activities that will disturb wetlands, and immediately after activities that will temporarily disturb wetlands. In all other cases, except for category I wetlands, compensatory projects should be completed prior to use or occupancy of the activity or development which was conditioned upon such compensation. Construction of compensation projects shall be timed to reduce impacts to existing wildlife and flora. Cooperative Restoration, Creation or Enhancement Projects. a. The Director may encourage, facilitate, and approve cooperative projects wherein a single applicant or other organization with demonstrated capability may undertake a compensation project with funding froin other applicants under the following circumstances: CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Page 27 February 20, 1992 16.20. A. 16.20. A. i. Restoration, creation or enhancement at a particular site may be scientifically difficult or impossible; or ii. Creation of one or several larger wetlands may be preferable to many small wetlands. Persons proposing cooperative compensation projects shall: i. Submit a joint permit application; ii.

Agricultural Lands. A. Purpose. The conservation and protection of agricultural lands on Bainbridge Island are considered economically and nutritionally beneficial. Protection of these lands will enhance the cultural and economic diversity and retain the rural character of the Island. Right to Farm. 1. The City declares that an agricultural operation that is in conformance with United States Department of Agriculture Best Management Practices, is not a public or private nuisance. 2. No agricultural operation or any of its appurtenances will be considered by the City to be or become a nuisance, private or public, by any changes in or on the surrounding land; provided that the provisions of this subsection shall not apply whenever a nuisance results from the unlawful operation of any such agricultural operation or its appurtenances. Co Standards. 1. All plats, development permits, and building permits issued for development activities on, or within three hundred feet of lands registered as agricultural lands and open space will contain a notice that the subject property is within or near agricultural lands on which a variety of commercial activities may occur that are not compatible with residential development. 2. All subdivisions, plats, and PUDs, shall provide an adequate buffer and/or cluster development from agricultural operations. 16.20.190 Forest Resources A. Purpose. Forests are valued for their contribution to aquifer recharge, wildlife habitat, rural status, and recreational opportunities, as well as timber and other torest products. It is through the proper management of forestry that environmental benefits will also accrue in areas of enhanced water quality, air quality, reduction of soil erosion, control of storm water runoff, provision of scenic and recreational CITY OF BAINBRIDGE ISLAND ESA ORDINANCE #92-07 Page 37 February 20, 1992 spaces, and providing a valuable buffer of a natural ecological equilibrium, as well as providing a renewal resource. Classification. The classification guidelines for forest lands is to be based upon the private land grades of the Department of Revenue (WAC 458-40-530). This system incorporates consideration of growing capacity, productivity and soil composition of the land. Forest lands of long-term commercial significance will generally have a predominance of the higher private forest land grades. However, the presence of lower private forest land grades within the areas of predominately higher grades need not preclude designation as forest land. Forest Practices Applications. Forest Practices are uses and activities relating to the growing, harvesting and limited processing of timber. This includes, but is not limited to (1) site preparation and regeneration; (2) protection from insects, fire and disease; (3) silvicultural practices such as thinning, fertilization and release from competing vegetation; and (4) harvesting. Forest practices do not include log storage. D, Standards/Regulations. 1. All timber harvesting shall be done in compliance with the current rules and regulations adopted under the Forest Practice Act and the Timber, Fish and Wildlife agreement or their successor. 2. Replanting or seeding required under Forest Practice regulations shall be accomplished within 18 months of harvest. 3. When timberland is to be converted to another use, such conversion shall be clea~y indicated on the Forest Practice application. Failure to indicate the intent to convert the timberland to another use on the application shall provide adequate grounds ti>r denial of subsequent permits or proposals for a period of six years from date of Forest Practices application approval (RCW 76-09-060(3)(b)(i). Timber harvest shall not be permitted until plat approval or other applicable land use authorization has been given and any required permits have been issued for the land division and intended subsequent use. In reviewing and regulating Forest Practices Applications that are Class IV Conversions, the following standards shall apply within the City: a. gainbridge Island Municipal Code and related ordinances, including but not limited to Zoning, Subdivision Standards, Short Plat requirements, and SEPA. b. gainbridge Island Subarea Plan policies; c. City of Bainbridge Island (formerly Winslow) Comprehensive Plan Development in areas currently used for forest land shall be clustered where possible; inclusion of such areas in open space should be encouraged whenever possible. Page 38 February 20, 1992 CITY OF BAINBRIDGE ISLAND ESA ORDINANCE//92-07 16.20.200. Mining. A. Purpose. The purpose of this section is to establish management policies which rigidly control the operation of the excavation of sand and other minerals, as well as gravel pits in the City, and meet the requirements of the State Growth Management Act to identify and classify mineral resource lands from which the extraction of minerals can be anticipated. Applicability. Mining is the removal and primary processing of naturally occurring materials from the earth for economic use. For purposes of this definition, "processing" includes screening, crushing, stockpiling, all of which utilize materials removed from the site where the processing activity is located. Mining activities also include in-water dredging activities related to mineral extraction. Processing does not include general manufacturing, such as the manufacture of molded or cast concrete or asphalt products, asphalt mixing operations, or concrete batching operations. General Regulations: 1. Excavation of sand, gravel, and other minerals shall be done in strict conformance to the Washington State Surface Mining Reclamation Act (Chapter 78.44 RCW) and applicable provisions of the City of Bainbridge Island Code, and other regulations. 2. Mining operations shall comply with all local, state and federal water quality standards and pollution control laws. Operations shall utilize effective techniques to prevent or minimize surface water runoff, erosion and sedimentation; prevent reduction of natural flows; protect all areas froin acidic or toxic materials; and maintain the natural drainage courses of all streams. Surface water runoff shall be impounded as necessary to prevent accelerated runoff and erosion. 3. Overburden, mining debris and railings shall not be placed in water bodies or floodways and shall be stored and protected in such a manner so as to prevent or minimize erosion or seepage to surface and ground waters. If substantial evidence indicates that mining operations are causing, or continuation of operation would cause, significant adverse impacts to water quality or to the geo-hydraulic functioning of a stream, the City of Bainbridge Island may terminate the mining permit or impose further conditions on the mining operation. In no case shall mining operations impair lateral support and thereby result in earth movements extending beyond the boundaries of the site. Precautions shall be taken to insure that the stagnant or standing water, especially that of a toxic or noxious nature, does not develop, and that flooding and evaporation will not lead to the stranding of fish in open pits.
