A. These sections establish regulations pertaining to the development of critical areas, as required under the Growth Management Act of 1990 (Chapter 36.70A RCW). State guidelines for classification and protective methods for critical areas are addressed in Chapter 365-190 WAC. “Critical areas” are wetland areas, aquifer recharge areas, frequently flooded areas, geologically hazardous areas, and fish and wildlife habitat conservation areas.

B. The purpose of these local regulations is to protect the environmentally sensitive resources of the city of Chehalis by establishing minimum standards for development of properties which contain or adjoin environmentally sensitive features and thus protect the public health, safety and welfare in regard to critical areas. The city is classifying all required categories of critical areas throughout the city and implementing development regulations to address these areas through these chapters. These standards serve to preclude land uses and developments which are incompatible with critical areas by:

1. Protecting the public from personal injury, loss of life or property damage due to flooding, erosion, landslides, seismic events, or soil subsidence;

2. Protecting against publicly financed expenditures to address improper use or improper management of critical areas;

3. Preventing degradation of the natural environment;

4. Protecting unique, fragile, and valuable elements of the environment;

5. Including the best available science in developing policies and development regulations to protect the functions and values of critical areas;

6. Giving special consideration to conservation or protection measures necessary to preserve or enhance anadromous fisheries;

7. Alerting property owners, potential buyers or lessees, appraisers, assessors, and others to the existence of and the development limitations of critical areas;

8. Providing city officials with sufficient information to adequately protect critical areas when approving, conditioning or denying public or private development proposals;

9. Meeting the requirements of the National Flood Insurance Program and maintaining Chehalis as an eligible community for federal flood insurance benefits. [Ord. 849B § 2, 2009.]

17.21.020 Applicability.

This chapter establishes designations and regulations for the protection of all properties which are critical areas. Properties listed, identified, designated, classified or rated as critical areas are those so designated on the resource maps referenced in this chapter, or by separate studies which indicate that all or portions of a particular area or specific site are environmentally sensitive or critical areas. A site-specific analysis which indicates that any element regulated by this chapter is present will result in a property being classified as an environmentally sensitive critical area. Land uses or developments proposed on or adjacent to sites which are critical areas shall comply with the provisions of this chapter. “Critical areas” are wetlands, frequently flooded areas, critical aquifer recharge areas, geologically hazardous areas, and critical fish and wildlife habitat conservation areas. [Ord. 849B § 2, 2009.]

17.21.030 Definitions.

Definitions of terms used in this chapter are:

“Accessory structure” means a structure that is incidental and subordinate to a primary use. Barns, garages, storage sheds, and similar structures are examples.

“Activity” means human activity associated with the use of land or resources.

“Adaptive management” means using scientific methods to evaluate how well regulatory and nonregulatory actions protect the critical area. An adaptive management program is a formal and deliberate scientific approach to taking action and obtaining information in the face of uncertainty. Management policy may be adapted based on a periodic review of new information.

“Agricultural activities” means those activities directly pertaining to the production of crops or livestock including, but not limited to, cultivation, harvest, grazing, animal waste storage and disposal, fertilization, the operation and maintenance of farm and stock ponds or drainage ditches, irrigation systems, canals, and normal maintenance, repair, or operation of existing serviceable structures, facilities, or improved areas. Activities that bring an area into agricultural use are not agricultural activities.

“Agricultural land” is land primarily devoted to the commercial production of horticultural, viticultural, floricultural, dairy, apiary, or animal products, or of berries, grain, hay, straw, turf, seed, Christmas trees not subject to the excise tax imposed by RCW 84.33.100 through 84.33.140, or livestock, and/or lands that have been designated as capable of producing food and fiber, which have not been developed for urban density housing, business, or other uses incompatible with agricultural activity.

“Alluvial fan” means a fan-shaped deposit of sediment and organic debris formed where a stream flows or has flowed out of a mountainous upland onto a level plain or valley floor because of a sudden change in sediment transport capacity (e.g., significant change in slope or confinement).

“Alluvium” is a general term for clay, silt, sand, gravel, or similar other unconsolidated detrital materials, deposited during comparatively recent geologic time by a stream or other body of running water, as a sorted or semi-sorted sediment in the bed of the stream or on its floodplain or delta.

“Alteration” means any human-induced change in an existing condition of a critical area or its buffer. Alterations include but are not limited to grading, filling, channelizing, dredging, clearing (vegetation), draining, construction, compaction, excavation, or any other activity that changes the character of the critical area.

“Aquifer susceptibility” means the ease with which contaminants can move from the land surface to the aquifer based solely on the types of surface and subsurface materials in the area. Susceptibility usually defines the rate at which a contaminant will reach an aquifer unimpeded by chemical interactions with the vadose zone media.

“Aquifer vulnerability” is the combined effect of susceptibility to contamination and the presence of potential contaminants.

“Base flood” is a flood event having a one percent chance of being equaled or exceeded in any given year, also referred to as the 100-year flood. Designations of base flood areas on flood insurance map(s) always include the letters A (zone subject to flooding during a 100-year flood, but less so than V zones) or V (zone subject to the highest flows, wave action, and erosion during a 100-year flood).

“Bedrock” is a general term for rock, typically hard, consolidated geologic material that underlies soil or other unconsolidated, superficial material or is exposed at the surface.

“Best available science” means information from research, inventory, monitoring, surveys, modeling, synthesis, expert opinion, and assessment that is used to designate, protect, or restore critical areas. As defined by WAC 365-195-900 through 365-195-925, best available science is derived from a process that includes peer-reviewed literature, standard methods, logical conclusions and reasonable inferences, quantitative analysis, and documented references to produce reliable information.

“Best management practices” means conservation practices or systems of practices and management measures that reflect the current scientific and technical consensus on the best or most effective means of addressing adverse effects upon a resource.

“Buffer” means the area adjacent to the outer boundaries of a critical area, such as wetlands; habitat conservation (streams, marine shorelines habitat areas); and/or landslide hazard areas, that provides an area for related ecological functions to take place and/or separates and protects critical areas from adverse impacts associated with adjacent land uses.

“Channel migration zone” means the area along a river or stream within which the channel can reasonably be expected to migrate over time as a result of normally occurring processes. It encompasses that area of current and historic lateral stream channel movement that is subject to erosion, bank destabilization, rapid stream incision, and/or channel shifting, as well as adjacent areas that are susceptible to channel erosion.

“City” means the city of Chehalis, Washington.

“Clearing” means the removal of vegetation or plant cover by manual, chemical, or mechanical means. Clearing includes, but is not limited to, actions such as cutting, felling, thinning, flooding, killing, poisoning, girdling, uprooting, or burning.

“Compensatory mitigation” means a mitigation project for the purpose of replacing, at an equivalent or greater level, unavoidable critical area and buffer impacts that remain after all appropriate and practicable avoidance and minimization measures have been implemented. Compensatory mitigation includes, but is not limited to, wetland creation, restoration, enhancement, and preservation; stream restoration and relocation, rehabilitation; and buffer enhancement.

“Debris torrent” means a violent and rushing mass of water, logs, boulders and other debris.

“Deepwater habitats” means permanently flooded lands lying below the deepwater boundary of wetlands. Deepwater habitats include environments where surface water is permanent and often deep, so that water, rather than air, is the principal medium in which the dominant organisms live. The boundary between wetland and deepwater habitat in the riverine and lacustrine systems lies at a depth of two meters (6.6 feet) below low water; however, if emergent vegetation, shrubs, or trees grow beyond this depth at any time, their deepwater edge is the boundary.

Ditches are graded (manmade) channels installed to collect and convey runoff from fields and roadways. Ditches may include irrigation ditches, waste ways, drains, outfalls, operational spillways, channels, storm water runoff facilities or other wholly artificial watercourses, except those that directly result from the modification to a natural watercourse. Ditched channels that support fish are considered to be streams.

“Emergency” refers to an unanticipated and imminent threat to public health, safety or the environment. Emergency construction does not include development of new permanent protective structures where none previously existed. As a general matter, flooding or other seasonal events that can be anticipated and may occur but that are not imminent are not an emergency.

“Emergent wetland” means a wetland with at least 30 percent of the surface area covered by erect, rooted, herbaceous vegetation as the uppermost vegetative strata.

“Erosion hazard areas” means lands or areas underlain by soils identified by the U.S. Department of Agriculture Natural Resource Conservation Service (NRCS) as having severe or very severe erosion hazards and areas subject to impacts from lateral erosion related to moving water such as river channel migration and shoreline retreat.

“Essential public facility” means those facilities that are typically difficult to site, such as airports, state education facilities, and state or regional transportation facilities, state and local correctional facilities, solid waste handling facilities, and inpatient facilities including substance abuse facilities, mental health facilities, and group homes.

“Feasible alternative” means a course of action that can include uses, design, construction techniques, and other features on a site or alternative sites that are reasonably capable of being carried out after taking into consideration existing technology and logistics and that has less impact to critical areas. Cost is one factor in determining whether an action is capable of being carried out.

“Fill material” means any solid or semi-solid material, including rock, sand, soil, clay, plastics, construction debris, wood chips, overburden from mining or other excavation activities, and materials used to create any structure or infrastructure, that when placed, changes the grade or elevation of the receiving site.

“Filling” means the act of transporting or placing by any manual or mechanical means fill material from, to, or on any soil surface, including temporary stockpiling of fill material.

“Fish and wildlife habitat conservation areas” are areas important for maintaining species in suitable habitats within their natural geographic distribution so that isolated populations are not created.

“Fish habitat” means a complex of physical, chemical, and biological conditions that provide the life supporting and reproductive needs of a species or life stage of fish. Although the habitat requirements of a species depend on its age and activity, the basic components of fish habitat in rivers, streams, ponds, lakes, estuaries, marine waters, and nearshore areas include, but are not limited to, the following:

1. Clean water and appropriate temperatures for spawning, rearing, and holding;

2. Adequate water depth and velocity for migrating, spawning, rearing, and holding, including off-channel habitat;

3. Abundance of bank and in-stream structures to provide hiding and resting areas and stabilize stream banks and beds;

1. There is no portion of the site under contiguous ownership not subject to critical area regulations where the provisions of this chapter allow reasonable economic use, including agricultural use, forestry use or continuation of legal nonconforming uses;

2. There is no feasible on-site alternative to the proposed use or activities that will provide reasonable economic use, including location on any contiguous parcel that has been under the ownership or control of the applicant since the effective date of the ordinance codified in this chapter; other allowed uses; continuation of legal nonconforming uses; reduction in size, change in timing of activities, revision of road and lot layout, and/or related site planning considerations, that would allow a reasonable economic use with less adverse impacts to critical areas and associated buffers;

3. 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/or creating the condition of lack of use after the effective date of the ordinance codified in this chapter;

4. All reasonable methods, to avoid or reduce adverse effects on critical area functions and values have been employed, including locating activities as far as possible from critical areas and design that will result in the minimum alteration of critical areas and associated buffers, existing topography, vegetation, fish and wildlife resources, hydrological conditions, and geologic conditions. Where both critical areas and buffer areas are located on a parcel, buffer areas shall be disturbed in preference to the critical area;

5. The project includes compensatory mitigation for unavoidable impacts to critical area and buffers in accordance with the mitigation requirements of this chapter;

6. The proposed activities will not result in adverse effects on endangered or threatened species as listed by the federal government or the state of Washington, or be inconsistent with an adopted recovery plan;

7. The proposed activities will not result in damage to nearby public or private property and no threat to the health or safety of people on or off the site;

8. The proposed activities will not lead to degradation of groundwater or surface water quality and will comply with all state, local and federal laws, including those related sediment control, pollution control, floodplain restrictions, and on-site wastewater disposal.

C. Nonconforming single-family residential lots meeting the criteria of CMC 17.21.088(F) shall not be required to meet criteria in subsections (B)(1), (2) and (5) of this section.

D. An application for a critical areas reasonable use exception shall follow the procedures for a special use permit review pursuant to Chapter 17.09 CMC, except that approvals in accordance with subsection (C) of this section shall be approved by the director in accordance with the approval procedure for the underlying permit.

E. An application for variance to provisions of this code may be considered in accordance with variance provisions in CMC 17.09.190. [Ord. 849B § 2, 2009.]

17.21.084 Density credits.

A. Critical areas and their buffers may be used in the calculation of allowed density to the extent provided by the zoning code and shoreline master program.

B. Full density as allowed by underlying zoning and minimum residential density goals may not be attained on specific parcels where critical areas impose inherent limitations on development intensity. [Ord. 849B § 2, 2009.]

17.21.085 Notice on title.

A. The owner of any property containing critical areas on which a development proposal is approved shall file with the records division of Lewis County a notice in a format approved by the director and provide a copy of the filed notice to the city of Chehalis planning department, unless notice is provided on a plat as provided in subsection (B) of this section. The notice shall:

1. State the presence of the critical area and/or buffer area on the property, and identify that there are limitations and restrictions on uses and actions in or affecting the critical area and/or buffer imposed by this code and by the provisions of the critical areas code and specific conditions of approval. The notice shall indicate that the restrictions run with the land and may be altered only in conjunction with amendment of this chapter or amendment of specific conditions of approval as provided by this chapter.

2. Provide that management of the critical area is required to include, but is not limited to, maintenance or replacement of vegetation to assure the long-term viability of a community of native vegetation, control of invasive plant control, and fulfillment of other conditions of approval.

3. Provide for the right of the public, and specifically the city of Chehalis, to enforce the terms of the restrictions through civil infraction or other legal address.

4. If a site plan has been approved indicating the extent of the critical area and buffer and permit conditions, a copy of the site plan together with relevant survey information and permit conditions shall be included in the notice filed.

B. Restrictions on use and development of critical areas buffers and setback areas on plats and short plats shall include the information in subsection (A) of this section, shall designate the party responsible for maintenance of the critical area, if other than the property owner, and shall place critical areas in tracts or easements as provided below:

1. Designation of separate tracts for critical areas and buffers shall be the preferred method of designation and protection of critical areas in plats to provide for integrated management of the critical area and buffer separately from lots. The tract may be:

a. Held in an undivided interest by each owner of a building lot within the development, the ownership of which shall pass with the ownership of the lot. Responsibility for meeting all requirements of preservation and management shall be designated to an incorporated homeowner’s association or other legal entity that assures the ownership and protection of the critical area.

b. Dedicated to the city of Chehalis or other governmental entity qualified to own and manage open space.

c. Conveyed to a nonprofit land trust, provided the land may not be thereafter transferred to a private party; and provided, that if the land trust is dissolved or otherwise fails to perform its functions, ownership and responsibility for management shall devolve to an undivided interest by each owner of a building lot within the development, as provided in subsection (B)(1)(a) of this section.

2. The director may allow a critical area and buffer to be placed within a protective easement on a parcel with the responsibility for meeting all requirements of preservation and management placed on the owner of the parcel over which the easement is placed. This means of designation shall be used in cases where the size and the ecological functions of the critical area do not require coordinated management or where formation of an incorporated homeowner’s association or other legal entity for management is found to be impractical because of the limited number of lots, or where ownership and management by the city, a qualified special district or a land trust is found to be impractical. This alternative generally will be limited to critical areas and buffers of less than 20,000 square feet and developments of fewer than 10 parcels, or commercial or multifamily development.

C. This notice on title shall not be required for a development proposal by a public agency or public or private utility within a right-of-way or easement for which they do not have fee-simple title.

D. The applicant shall submit proof that the notice, dedication or easement has been filed for public record before the city shall approve any final plat or final site plan for such site. The notice shall run with the land and failure to provide such notice to any purchaser prior to transferring any interest in the property shall be a violation of this section. [Ord. 849B § 2, 2009.]

17.21.086 Building setbacks.

A. Buildings and other structures shall be set back a sufficient distance to assure that disturbance to sensitive area vegetation and soils is avoided during construction, maintenance and use.

B. Buildings and other structures shall be set back a distance of 10 feet from the edges of all critical area buffers or from the edges of all critical areas if no buffers are required; provided, that the director may modify the building setback based on specific development plans that document that construction techniques, maintenance needs and use will not disturb critical areas or buffer.

C. If slopes adjacent to the buffer for wetlands or water bodies exceed 15 percent, including slopes created by grading, a swale sufficient to intercept surface water movement shall be installed outside the edge of the buffer.

D. The following facilities and uses are allowed in the building setback:

1. Landscaping, including rockeries not over 42 inches high, provided construction does not alter the buffer or critical area;

2. Uncovered decks, platforms, porches and similar projections not over 42 inches high;

3. Building eaves, cornices, chimneys and similar projections no greater than two feet into the building setback;

4. Impervious surfaces such as driveways, parking lots, roads, and patios; provided, that such surfaces conform to applicable water quality standards and that construction equipment does not enter the buffer or critical area;

5. Clearing and grading consisting of not over 42 inches of cut or fill. [Ord. 849B § 2, 2009.]

17.21.087 Mitigation.

A. Mitigation measures shall be implemented to protect critical areas and buffers from alterations occurring on all or portions of a site being developed. The mitigation measures required below shall be implemented in conjunction with other applicable mitigation requirements outlined in the subsequent sections of this chapter.

B. For purposes of this chapter, “mitigation” means the use of the following actions that are listed in descending order of preference:

1. Avoiding the impact altogether by not taking a certain action or parts of an action;

2. Minimizing impact 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 impact;

3. Rectifying the impact by repairing, rehabilitating or restoring the critical areas;

4. Reducing or eliminating the impact over time by prevention and maintenance operations;

5. Compensating for the impact by replacing, enhancing or providing substitute areas and environments and replacing the ecological processes and functions of the resource;

6. Monitoring the impact and taking appropriate corrective measures.

C. Location. Compensatory mitigation shall be provided on site or off site in the location that will provide the greatest ecological benefit and have the greatest likelihood of success. Off-site mitigation is preferred close as possible to the impact area and within the same watershed sub-basin as the permitted alteration. Off-site mitigation sites preference shall be given to sites and restoration activities identified in an adopted shoreline restoration plan pursuant to Chapter 173-26 WAC, a watershed planning document prepared and adopted pursuant to Chapter 90.82 WAC, a watershed restoration project pursuant to RCW 89.08.460, a salmonid recovery plan, the Salmon Recovery Board Habitat Project List, or identified by the Washington Department of Fish and Wildlife as essential for fish and wildlife habitat enhancement pursuant to RCW 77.55.290.

D. Mitigation Plan. A mitigation plan shall be required for the design, implementation, maintenance and monitoring of mitigation. A plan shall provide the following, in addition to criteria for the specific critical areas provided below for individual critical areas:

1. A description and evaluation of any critical areas that could be altered by the proposed development, including evaluation of ecological processes and functions based on best available science and detailed field assessment of the affected resources;

2. A description and scaled drawings of the proposed mitigation activities including, but not limited to, clearing, grading/excavation, drainage alterations, planting, invasive plant management, installation of habitat structures, irrigation, and other site treatments;

3. A description of the ecological functions and values that the proposed alteration may affect and of the specific ecological functions and values the proposed mitigation area(s) shall provide;

4. A description of required or recommended mitigation ratios and an assessment of factors that may affect the success of the mitigation program;

5. Specific measurable performance standards that the proposed mitigation action(s) shall achieve together with a description of how the mitigation action(s) will be evaluated and monitored to determine if the performance standards are being met;

6. A description of potential courses of action, and any corrective measures to be taken if monitoring or evaluation indicates that project performance standards are not being met;

7. Cost estimates for the installation of the mitigation program, monitoring, and maintenance as well as for corrective action if mitigation performance standards are not met.

E. A performance assurance shall be provided to guarantee installation, monitoring and performance of mitigation actions.

1. Performance Surety. The applicant shall post a cash performance bond, letter of credit, or other security acceptable to the city of Chehalis in the amount of 125 percent of the estimated cost of the uncompleted actions or the estimated cost of restoring the functions and values of the critical area that are at risk, whichever is greater. The surety shall be based on an itemized cost estimate of the mitigation activity including clearing and grading, plant materials, plant installation, irrigation, weed management, monitoring, and other costs. The conditions of the surety shall be consistent with the purposes of this chapter and the conditions to be fulfilled. In the event of a breach of any condition of any such bond, the city of Chehalis may institute an action in a court of competent jurisdiction upon such bond and prosecute the same to judgment and execution. The city of Chehalis shall release the bond upon determining that:

a. All activities, including any required compensatory mitigation, have been completed in compliance with the terms and conditions of the permit and the requirements of this chapter;

b. Upon the posting by the applicant of a maintenance surety.

2. Maintenance Surety. The city of Chehalis shall require the holder of a development permit issued pursuant to this chapter to post a cash performance bond, letter of credit, or other security acceptable to the city of Chehalis in an amount and with surety and conditions sufficient to guarantee that structures, improvements and mitigation required by the permit or by this chapter perform satisfactorily, generally for a period of five years after they have been completed. The city of Chehalis shall release the maintenance bond upon determining that performance standards established for evaluating the effectiveness and success of the structures, improvements and/or compensatory mitigation have been satisfactorily met for the required period. For compensation projects, the performance standards shall be those contained in the mitigation plan developed and approved during the permit review process. The maintenance bond applicable to a compensation project shall not be released until the city of Chehalis determines that performance standards established for evaluating the effect and success of the project have been met. The director may return up to 50 percent of the surety following the first year of monitoring; provided, that the year one performance standards are met and the risk of subsequent failure is considered low.

3. Depletion, failure, or collection of surety funds shall not discharge the obligation of an applicant or violator to complete required mitigation, maintenance, or monitoring.

4. Public development proposals may be relieved from having to comply with the surety requirements of this section if public funds have been committed through a budget process with final approval for mitigation, maintenance, or monitoring.

F. Mitigation Banking. The city may approve mitigation banking as a form of compensatory mitigation for wetlands and fish and wildlife habitat conservation area impacts when the provisions of this chapter require mitigation and when it is clearly demonstrated that the use of a mitigation bank will provide equivalent or greater replacement of critical area functions and values when compared to conventional on-site mitigation; provided, that all of the following criteria are met:

1. Mitigation banks shall only be used when they provide significant ecological benefits including long-term conservation of critical areas, important species, habitats and/or habitat linkages, and when they are consistent with the city’s comprehensive plan and create a viable alternative to the piecemeal mitigation for individual project impacts to achieve ecosystem-based conservation goals.

2. The mitigation bank shall be established in accordance with the Washington State Draft Mitigation Banking Rule, Chapter 173-700 WAC or as revised, and Chapter 90.84 RCW and the federal mitigation banking guidelines as outlined in the Federal Register Volume 60 No. 228, November 28, 1995. These guidelines establish the procedural and technical criteria that banks must meet to obtain state and federal certification.

3. Preference shall be given to mitigation banks that implement restoration actions that have been identified in an adopted shoreline restoration plan, watershed planning document prepared and adopted pursuant to Chapter 90.82 RCW, a salmonid recovery plan or project that has been identified on the Salmon Recovery Board Habitat Project List or by the Washington Department of Fish and Wildlife as essential for fish and wildlife habitat enhancement. [Ord. 849B § 2, 2009.]
