ATTACHMENTS: Proposed Ordinance Exhibit A Planning Commission Agency Report SUMMARY STATEMENT: Please complete sections of box as appropriate & explain the item below. Related County contract #: n/a I Should Clerk schedule a hearing? NO / / YES /x/ Requested date: August 12, 1997 Amount budgeted for this item/project: $ n/a Is it (or will it be) within budget? YES /X/ NO / / (Please explain below) n/a Budget line item number(s): n/a The request is to replace Ordinance #96 -032 with a permanent ordinance, to be adopted as Chapter 16.16, Whatcom County Code, "Critical Areas" (see Exhibit "A "). This request is made in response to a Western Washington Growth Planning Hearings Board ruling on September 12, 1996. In the ruling, the Board invalidated Articles IX (Wetlands), X (River and Streams), XI (Fish Habitat Conservation Areas), and XII (Wildlife Habitat Conservation Areas) citing non - compliance with the Growth Management Act and remanded the CAO back to the county for compliance within 180 days of the order. Several Emergency and Interim Ordinances have been adopted to protect Critical Areas while the County was working on a permanent ordinance, the most recent of which is Ordinance 97 -032, which will expire January 9, 1998. The Planning Commission held two public hearings and seven public work sessions on the proposed ordinance. These Critical Area Regulations will provide adequate protection to Critical Areas and bring the County into compliance with the Growth Management Act. ORIGINATOR'S RECOMMENDED ACTION. • The Planning and Development Services Director recommends that Council accept the recommendation and adopt the proposed ordinance.

A 1995 amendment to the Growth Management Act, RCW 36.70A.172, requires 18 counties to include the best available science in developing regulations to protect 19 the functions of critical areas, and to give special consideration to conservation or ?0 protection measures necessary to preserve or enhance anadromous fisheries. 21 2. Riparian buffer width recommendations by scientific investigations varies widely 22 depending upon the specific functions to be maintained. Most of the research 23 suggests buffers of approximately 30 meters to protect water quality and salmonid 24 habitat, buffers of approximately 15 meters to maintain erosion and shoreline 25 protection, and buffers ranging from 15 meters to greater than 30 meters for 26 maintaining various wildlife functions. 27 3. Buffers are unnecessary to protect wetlands that primarily. provide storm water 28 storage or attenuation functions. Buffer protection where it does not serve to 29 protect any function not only directs development toward areas which may 30 possess equal or greater environmental value, it also causes the needless 31 expenditure of time and money as property owners respond to additional regulation 32 for no significant beneficial purpose. 33 4. While fixed width riparian buffers offer predictability and ease in administration and 34 enforcement, such buffers may also result in arbitrarily protecting some function 35 that may not exist in an area. 36 5. Variable width buffers allow greater flexibility for the County and landowners, as 37 they can be appropriately tailored to existing site conditions and functions. 2 1 Variable buffers entail a more costly and time - consuming process, but will protect 2 the environment more completely without undue losses to landowners. 3 6. Most published scientific literature on the effectiveness of riparian buffers focuses 4 primarily upon protecting or maintaining functions without any direct connections 5 to stream typing or wetland categorization. 6 7. Adopting any one particular wetland or stream functional assessment method 7 precludes flexibility in choosing the method best suited to a particular area. In 8 addition, other agencies involved in regulating a given wetland may require a 9 different method than one specified in an ordinance. This may result in greater 10 cost for an applicant without benefit. 11 8. Functional assessment is useful in determining the potential functions of existing 12 systems. While assessment models have no direct relationship to the 13 establishment of protective buffer dimensions, they assist in determining what 14 functions are present to protect or mitigate. 15 9. The addition of clear administrative procedures, and the re- organization and 16 removal of unnecessary text, will create a document more understandable to the 17 public and reduce administrative discretion. 18 10. Based upon National Wetlands Inventory data, it is estimated that in Western 19 Whatcom County there are 528 isolated wetlands outside of standard stream buffers that are less than one third of an acre in size. These 528 wetlands total 21 approximately 94 acres. State and Federal wetland rules maintain standard 22 exemptions for isolated wetlands less than one third acre. 23 11. Allowing a minor level of exemptions which does not significantly .effect critical 24 areas is reasonable and necessary. Their exclusion from this regulatory scheme is 25 warranted in light of the competing interests of affordable housing, minimizing 26 intrusion on private property interests, encouragement of economic development, 27 and expediting the permit process. 28 12. In most cases it is unnecessary to duplicate regulations adopted and administered 29 by other jurisdictions such as the state and federal governments, and such 30 duplication was not the intent of the Growth Management Act. 31 13. Maintenance and enhancement of the local agricultural economy and of the 32 functions of critical areas at times represent competing interests which the County 33 must seek to balance as it adopts regulations to protect critical areas. 34 14. The intricacies of agricultural practice, as well as the many variables involved, call 35 for a level of expertise to properly regulate the areas where agricultural land, 36 wetlands, aquifer recharge areas and /or streams intersect. Ic 1 15. The Whatcom Conservation District has a history of successful cooperation with 2 county farmers to achieve maintenance and enhancement of critical areas in 3 conjunction with agriculture. 4 16. The additional designation and protection of Frequently Flooded Areas and Fish and 5 Wildlife Habitat Conservation Areas, as described by WAC 365 -190, will result in 6 greater compliance with the Growth Management Act. 7 17. Shellfish habitat conservation areas in Whatcom County are threatened by a 8 number of bacterial sources including failing sewer and storm water systems, 9 failing septic systems, storm water runoff, and poor agricultural, practices. State 10 rules and municipalities govern sewer systems. Storm water discharges in 11 unincorporated areas are controlled through the Whatcom County Development 12 Standards. Failing septic systems are unlawful under County and State on -site 13 sewage system rules. Agricultural runoff violates Clean Water Act rules at times 14 enforced by the State Department of Ecology and Federal Environmental Protection 15 Agency. Nevertheless, and without undue regulatory overlap, Whatcom County 16 can further protect shellfish areas through the protection of wetland, river and 17 stream functions, namely the maintenance of water quality. In addition, further 18 protection can occur by a requirement for storm water discharges to meet state i9 water quality, standards, farmers to write and abide by conservation plans utilizing 20 best management practices, and septic system owners to write maintenance 21 agreements with the County governing their proper use. 2 18. The amendments contained in Exhibit "A" constitute Whatcom County's response 23 to the Growth Hearings Board ruling on September 12, 1996, the Growth 24 Management Act, as amended, and regulatory reform efforts to streamline 25 regulations. 26 CONCLUSION 27 These Critical Areas Regulations as amended will provide adequate protection.to. Critical 28 Areas and bring Whatcom County into compliance with the Growth Management Act. 29 The adoption process has been sufficient to comply with the public participation 30 requirements of the GMA. 4 1 NOW, THEREFORE, BE IT ORDAINED by the Whatcom County Council that: 2 Section 1. Whatcom County hereby amends Chapter 16.16, Whatcom County Code, 3 "Critical Areas," by repealing the existing Interim Chapter 16.16 and replacing it with the 4 new Chapter 16.16 text attached as Exhibit A. 5 Section 2. Adjudication of invalidity of any of the articles, sections, clauses, or 6 provisions of this Ordinance shall not affect or impair the validity of the ordinance as a 7 whole or any part thereof other than the part so declared to be invalid. 9 10 ADOPTED this 21 day of October ATTEST: 13 14 15 APPROV as to form- Karen Frakes, Civil Deputy Prosecutor 1997.

Subject to the variance provisions of section 16.16.255, any proposed critical area or buffer alteration that cannot adequately mitigate its impacts to a regulated critical area shall be denied. A. . Mitigation Guideline 1. Projects otherwise permitted pursuant to this chapter shall avoid, minimize, or mitigate for adverse impacts to the functions of regulated critical areas or their buffers by one or more of the following, in a manner such that the most effective protection or mitigation to critical area functions will take CRITICAL AREAS ORDINANCE - NOVEMBER, 1997 place with the greatest likelihood of success: L•7 a. Avoiding the adverse impact altogether by not taking a certain action or parts of an action; b. Minimizing_ adverse impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology, or by taking affirmative steps to avoid or reduce adverse impacts; C. Rectifying the adverse impact by repairing, rehabilitating or restoring - the affected environment; d. Reducing or eliminating the adverse impact over..time_ by preservation .. and maintenance operations during the life.of; action; e. Mitigating for the adverse impact by replacing;- enhancing, or providing substitute resources. or environments and monitoring.the adverse impact and the mitigation project and taking appropriate corrective measures. 2. Mitigation for individual projects may include a combination of the above measures. B. Off -Site Mitigation Off -site mitigation, including mitigation banking, may be accepted as appropriate mitigation under the following conditions: 1. On -site mitigation is not scientifically feasible due to hydrology, soils, waves, or other factors; or 2. On -site mitigation is not practical. due to potentially adverse impact from surrounding land uses; or 3. Mitigation occurs within an area where the most-significant improvement to the critical area will take place with the greatest likelihood of success, and 4. Mitigation occurs within the subbasin which is adversely impacted. "this provision may be waived upon demonstration through a watershed analysis that mitigation within an alternative subbasin of the same watershed would have greater ecological benefit than mitigation within the impacted subbasin. Mitigation may occur outside of the impacted watershed given the above demonstration on a watershed to watershed comparison and when no suitable site within the impacted watershed is available.

Listed _ Species: Listed species are those officially designated by the State Department of Fish and Wildlife and /or U.S. Fish & Wildlife Service as endangered, threatened, sensitive, or candidate (refer to species list in Appendix Q. These are species known to be experiencing or have experienced failing or declining populations due to factors such as limited numbers, disease, predation, exploitation, or a loss of suitable habitat. These species are in jeopardy of extirpation or extinction because of population declines. 1. Where a project is proposed within an area where listed species have a primary association, a habitat management plan will be required. The limits of.development and other related activities within the HCA shall utilize the recommendations of the plan. The habitat management plan shall be prepared in compliance with section 16.16.,730. CRITICAL AREAS ORDINANCE - NOVEMBER, 1997 27 2.

Habitats and. species ofJocal importance include habitat supporting both vulnerable1and-. recreational ly important species (refer to species list in Appendix GG) Vulnerable species. , includes those susceptible to significant population declines because they are uncommon (either within a specific area or statewide), have a very limited distribution, or have special space or habitat requirements. These characteristics make them particularly vulnerable to significant population declines because of disease, extreme weather, or loss of suitable habitat. Recreationally important species includes species (native or introduced) with high recreational importance (consumptive or non - consumptive) or high public profile and that are vulnerable to habitat loss or degradation. These species contribute to local economies and /or provide opportunities for human interaction that are especially valued by the public. 1. Where a project is proposed within an area where habitats and species of local importance have a primary association, and the Technical Administrator determines that habitat disruption is likely to occur from the project as proposed, then a habitat management plan will be required. The limits of development and other related activities within.the..HCA shall utilize the recommendations of the plan: -; The. habitat,m -anagement plan shall be prepared in compliance with section 16.16.730. 2. Activities may be permitted within an area where habitats and species of local importance have a primary association subject to conditions designed to avoid adverse impacts, provided that the county may deny a project if such impacts cannot be avoided. C. Shellfish Habitat Conservation Areas: Shellfish Habitat Conservation Areas are found in estuarine wetland systems, and are protected from dredging or filling activities through Article VI Wetlands, as well as the Washington State Department of Fish and Wildlife Hydraulic Project Approval process and through policies and regulations of the Whatcom County Shoreline Management Program, An addition, Shellfish Habitat Conservation Areas are protected from water quality impacts through the protection of wetlands, rivers and streams which protect water quality CRITICAL AREAS ORDINANCE - NOVEMBER, 1997 28 by establishing appropriate buffers from the ordinary high water mark of rivers, streams, and wetlands.

OVERVIEW OF PROGRAM A. Critical Areas Compliance There are two mechanisms through which property owners conducting agricultural activities can comply with applicable critical areas requirements. First, property owners can adhere to the requirements which pertain to all development activities as set forth in chapter 16.16 WCC Critical Areas.... Alternatively, such property owners can choose to meet the requirements set forth in the Conservation Program on Agriculture Lands (OPAL). This program requires property owners to develop conservation plans, and submit them to WCD for review and approval. The approval of conservation plans is based on their ability to meet the program's environmental quality standards, and their conformance with conservation practice standards developed primarily by the United States Department of Agriculture, Natural Resources Conservation Service (MRCS), formerly the Soil Conservation Service. Property owners are responsible for the preparation of conservation plans. B. WCD Responsibilities Whatcom Conservation District responsibilities include the following: • Review and approve, condition or disapprove all properly submitted conservation plans; • Provide assistance to property owners participating in the program at the. level and to the degree 42 they request it; • Assist property owners in the development of site - specific conservation plans meeting the program's requirements. Conservation plans shall consist of a combination of structural tools and management practice standards, and shall be designed to protect potentially impacted critical areas; a While assisting property owners during the conservation plan development process, provide opportunities for property owner input and choice; • Where feasible, assist property owners to develop conservation plans which incorporate Federal, State or local cost -share or incentive programs; • Where applicable, provide technical assistance to property owners during the component- design and implementation phases of their plans; • Provide guidance. to property owners regarding ,operation and maintenance of incorporated structural tools and management systems; _ • Monitor and evaluate conservation plan effectiveness;.as•needed; a Be available to property owners to review and update conservation plans; which must be re- approved every five years; and • On an annual basis, report on the status of the program to the County Council. C. Whatcom County Responsibilities Whatcom County responsibilities include the following: • Inform property owners whose existing or planned agricultural activities are not in compliance with critical areas requirements about this conservation program and refer them to WCD; • Review and comment on proposed conservation plans; and • Enforce property owner compliance with approved conservation plans. ADMINISTRATIVE PROCESS This program requires property owner cooperation throughout the conservation plan development or approval processes. Property owners may be asked to provide information regarding present and future agricultural activities, and to allow WCD staff to Have access to the -subj ect properties with prior notification. A. Conservation Plan Development Property owners are responsible for the development and preparation of conservation plans, and may use whatever means available to them to do so. This may include preparing plans themselves, hiring someone else, or utilizing the assistance of WCD or the Whatcom County Technical Administrator. If WCD assistance is desired, the property owner must initiate this process by contacting WCD either in person or in writing. As a guide, it is recommended that property owners follow the steps in the WCD conservation plan development process, outlined below: 43 1. Inventory. Conduct an on -site agricultural/ environmental inventory. This inventory should identify both the principal agricultural activities -occurring on the property and the adjacent critical areas. Additional information regarding topography , soils, vegetation, and existing structures should also be gathered. Applicable Critical Areas, as defined in chapter 16.16 WCC Critical Areas, include: • Critical aquifer recharge areas; • Fish and Wildlife habitat conservation areas; • Wetlands; 2. Determination of property owner objectives and resources. Identify agricultural activities planned for the future. Determine what the property owner wants to accomplish through developing a conservation plan, as well as the available resources. 3. Analysis. Analyze the subject property, agricultural activities and critical areas, to determine the level of critical areas protection needed at various locations. As a starting point, WCD has divided agricultural activities into three broad categories, based on impact: low- impact, moderate - impact, and high- impact. See Table 1. Table l: Impact Categories for Agricultural Activities Low - impact Moderate - impact High - impact hayfields tilled cropland feed lots orchards pasture land manure lagoons woodlots berry fields confinement areas vineyards I fields receiving manure I heavy use areas This .categorization is understood to be somewhat generalized. The size and intensity of each activity must :also be taken into consideration along with other factors, such as: the distances separating agricultural activities from critical areas, the topography, existing vegetation, and soils. Critical areas should be identified based on county critical areas maps and on -site inspection by qualified specialists. 4. Formulation of alternatives and plan selection. Taking all of the above information into consideration, develop a site- specific plan, or plans. In some cases, there may be a number of way to achieve the necessary level of critical areas protection. For example, given an activity typically requiring a buffer separating it from a critical area, a reduced buffer width may be adequate, if sufficient vegetation is in place, or can be established. Property owners must select the plan which best fits with their objectives and available resources. Conservation plans which meet CPAL requirements consist of a combination of structural tools and management practice standards. Many such standards have been developed by NRCS and other 44 government agencies and institutions. A list of the tools and standards which WCD has determined to be most applicable to agricultural activities in Whatcom County is available from WCD, as well as information on each specific tool or standard. Information regarding the preparation of conservation plans is also available from WCD. If property owners choose to incorporate conservation practice standards or Best Management Practices from other sources, it must be demonstrated that these tools or practices will provide the necessary level of environmental protection. At the property owner's request, WCD can assist them in designing a conservation plan which goes beyond the protection of critical areas, and which looks more broadly toward developing the property's potential in terms of soil, water, air, plants, and animals. 5: Plan preparation. Prepare the selected conservation plan for submission to WCD, and include the following: .. The property owner's name; The address and legal description of the subject property; A nap which clearly shows the location of . -all.: critical = areas.:. and agricultural activities occurring on the property; Descriptions of the above critical areas and activities; .and A detailed description of the tools and /or management practices which will be incorporated into the plan, along with an explanation of how these components will provide the necessary level of critical areas protection. WCD will maintain a database containing information on property owners who are utilizing WCD assistance in the development of their conservation plans. Once a plan has been completed, the property owner can submit it to WCD for review and approval. B. Conservation Plan Submittal Property owners must submit three copies of their completed conservation plans to WCD, along with a signed letter stating that they are submitting the plan for WCD review and approval. C. Conservation Plan Review and Approval Upon receipt of a properly submitted conservation plan, WCD will forward;copies.to the Washington State Department of Fish and Wildlife, the -Department of Ecology, and the: Whatcom County Critical Areas Technical Administrator for a 20 day review and comment period. WCD, in consultation with NRCS, will approve, condition, or disapprove such a plan within thirty calendar days from the date the plan is received at the WCD office. If no. action is taken within thirty days, the conservation plan will be deemed approved. Conservation plans which are approved will be marked as such and returned to the property owner. WCD will also forward a copy of the approved plan to the Whatcom County Critical Areas Administrator who will maintain a file of all conservation plans for public inspection. If a conservation plan is disapproved, WCD will notify the,applicant in writing. This notification, 45 along with the disapproved plan, will be mailed to the property owner within ten days from the date the plan is disapproved, and will indicate those portions of the plan which do not meet the program's \ requirements. Property owners who receive notifications of conservation plan disapproval are encouraged to make the necessary modifications and resubmit their plans to WCD for approval. WCD will maintain a database containing conservation plan approval and disapproval information. D. Appeals Any property owner who receives notification of conservation plan disapproval may appeal the decision to the WCD Board, who will make a determination based on NRCS standards. If, after considering the matter, the Board denies the appeal, the property owner may appeal the decision to the county hearing examiner, pursuant to section 16.16.265 WCC. WCD will inform the Whatcom County.Critical Areas Technical Administrator, in writing, of all such appeals which have been denied. CONSERVATION PROGRAM REQUIREMENTS The CPAL Environmental Quality Standards and Conservation Practice Standards are included in the WCD Conservation Planning Handbook. Copies of the Handbook are available at WCD and Whatcom County Planning and Development Services. Environmental Quality Standards 1. Unless otherwise specified, conservation plans shall be developed to meet the Resource Management System Quality Criteria contained in section III of the NRCS Field Office Technical Guide. The following requirements also apply: 2. Conservation plans shall be developed so as to comply with Chapter 90.48 RCW: Water Pollution Control and all regulations including amendments which implement it. Such plans shaltmeet or exceed water quality standards as established in Chapter 173 -20.1A WAC: Water Quality Standards for Surface Waters of the State of Washington and Chapter 173 -200 WAC: Water Quality Standards for Ground Waters of the State of Washington. B. Conservation Practice Standards Conservation practices, sometimes referred to as "Best Management Practices," include physical or structural tools and/or management practices which, when used singularly or in combination, prevent or reduce the adverse impacts of agricultural activities on critical areas. WCD utilizes conservation practice standards drawn from several sources, the most significant of which is the NRCS, which began developing conservation standards in 1969. ]VRCS standards are described in detail in the NRCS National Handbook of Conservation Standards. These NRCS standards and others used by 46 WCD cover a wide range of subject areas, and provide guidelines and specifications for both structural tools and management practices. A complete listing of these standards, along with their specifications, is contained in the Conservation Practice Standards section of the WCD Conservation Planning Handbook. To assist property owners in the conservation planning process, WCD has divided these conservation practice standards into seven different groups based on the functions they perform. Many of the standards most commonly incorporated into conservation plans are indicated below. For each conservation plan, appropriate conservation practice standards must be, selected and applied on a case by case basis so as to achieve the necessary level of critical areas protection. If the applicable activities are present, standards from the first four groups must be incorporated into conservation plans. Titles of NRCS or other standards -are showninside °brackets Group 1: Critical Areas Management This group of standards covers limiting or controlling the access which livestock or other uses have to critical areas on a permanent, temporary, or seasonal basis [Livestock Exclusion/ Use Exclusion]. This is often achieved through the construction of appropriately located physical barriers [Fencing], or by developing animal crossing and watering point plans [Access Roads]. Standards which limit stream bank or stream channel erosion are also included in this group [Streambank and Shoreline Protection, Stream Channel Stabilization]. Group 2: Waste Management _ The NRCS has identified at least 19 different standards which pertain to the management of wastes. These include standards which specify appropriate livestock densities within a fully planned system [Waste Management Systems], the storage and treatment of wastes [Waste Storage Facility, Waste Treatment Lagoon], the use or field application of wastes [Nutrient Management], and runoff control [Filter Strip]. Group 3: Confinement Area Management This group of standards is closely related to the previous group and pertains�primarily to working with areas in which livestock are concentrated:= -The size and characteristics of livestock holding or feeding areas are covered [Managing Livestock Confinement and Holding Areas], as well as the management of runoff to reduce both erosion and the movement of pollutants [Roof Runoff Management]. Group 4: Cropland Management These standards are designed to reduce impacts to critical areas from croplands. This is accomplished through specifying the method, location, or timing of certain activities, such as cropland tilling [Residue Management], the use of pesticides [Pest Management], and the planting of crops to reduce erosion and sedimentation [Conservation Crop Rotation, Cover and Green Manure Crop, Buffer Striperopping]. 47 Standards drawn from groups 5 through 7 may be incorporated into plans when additional management, or critical areas protection or enhancement is necessary, or desired. Group 5: Grazing and Pasture Management This group of standards covers all aspects of managing pasture and grazing areas [Grazing Land Mechanical Treatment, Pasture and Hayfield Planting, and Prescribed Grazing]. Group 6: Buffer Enhancement This group contains standards which pertain to the planting or maintaining of critical area buffers. The size and composition of buffers, as well as their benefits, are covered [Tree/ Shrub Establishment, Riparian Buffers for Agricultural Lands]. Group 7: Critical Area Enhancement This group of standards specifies tools for protecting or improving rivers and streams [Fish Stream Improvement, Channel Vegetation], for managing or restoring wetlands [Wildlife Wetland Habitat Management, Wetland Development or Restoration], and for creating, maintaining or enhancing wildlife habitat [Wildlife Upland Habitat Management]. Any critical areas enhancement undertaken as a required component of a conservation plan shall not substitute for enhancement or mitigation measures required as a result of development activities pursuant to chapter 16.16 WCC Critical Areas. 48 APPENDIX B Sources of Groundwater Contamination and Associated Contacts for Technical Expertise Following is a list of potential sources which may contribute to groundwater contamination.
