This chapter shall be known, and shall be cited, as the Lewis County shorelines chapter. [Ord. 1279 §1, 2017; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1034 §1, 1974]

The purpose of this chapter is to implement the Shoreline Management Act of 1971 (Chapter 286, Laws of 1971, First Ex. Sess.), codified as Chapter 90.58 RCW. [Ord. 1279 §1, 2017; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1034 §2, 1974]

Standards for the regulation of shorelines in Lewis County are contained in the Lewis County shoreline master program adopted September 21, 2021, or as amended. Copies of the Lewis County shoreline master program shall be kept on file and shall be made available to the public at the office of the Lewis County department of community development. [Ord. 1329 §1, 2021; Ord. 1279 §1, 2017]

The fees for this chapter are set forth in LCC 18.05.120. [Ord. 1279 §1, 2017]

This chapter is established pursuant to RCW 36.70A.060 and shall be known as the Lewis County resource lands ordinance. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179C §1, 2003; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §1.1, 1996]

(1) The purpose of this chapter is to identify and conserve long-term commercially significant forest, agricultural, and mineral resource lands designated pursuant to this chapter as required by the Growth Management Act of 1990 (Chapter 17, Laws of 1990) by supplementing the development regulations contained in various ordinances of Lewis County and other applicable state and federal laws by providing additional controls and measures to conserve resource lands and protect human health and safety. This chapter is adopted under the authority of Chapters 36.70A and 36.70 RCW.

(2) The intent of this chapter is to facilitate the processing of relevant land use and development applications in a timely fashion with minimum intrusion on individual freedom, with a maximum of consistency and predictability. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §1.2, 1996]

(1) It is a policy of Lewis County that the resource lands supporting agriculture, forest, and mineral extractive industries be conserved as identified in this chapter, and further that reasonable associated and incidental uses be identified which aid and assure the economic viability of the long-term commercial resource user. Reasonable regulation shall be achieved by the balancing of individual and collective interests.

(2) The countywide planning policies identified private property rights as the primary priority and all applications of this chapter shall be cognizant and consistent with private property rights.

(3) No permit granted pursuant to this chapter shall remove an applicant’s obligations with respect to applicable provisions of any other federal, state, or local law or regulation, including, but not limited to, the acquisition of any other required permit or approval.

(4) Mitigation Priorities.

(a) Avoid the impact altogether by not taking a certain action or parts of any action where reasonable nonresource land alternatives are available;

(b) Minimize 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 impacts;

(c) Rectify the impact by repairing, rehabilitating, or restoring the affected environment;

(d) Reduce or eliminate the impact over time by preservation and maintenance of resource land functions during the life of the action;

(e) Compensate for the impact by replacing, enhancing, or providing substitute resources or environments in lieu of resource lands impacted; and/or

(f) Monitor the impact and take appropriate corrective measures where appropriate.

(5) Mitigation Application.

(a) Lewis County respects the right of property owners to use their property consistent with the guidelines presented. Priorities in subsection (4) of this section are preferences to guide development and may be mixed to facilitate reasonable use of property, with increasing mitigation applied to the greater impacts to protect the functions, systems, and values identified.

(b) The priorities in subsection (4) of this section shall not be used to deny a permit for activities specifically authorized on resource lands or buffers where reasonable nonresource land alternatives are unavailable.

(6) The assessor is required to consider the impact to property values by reason of restrictions in this chapter in assessing property in Lewis County.

(7) Existing property uses shall not be affected by this chapter. This chapter will apply only when regulations require a development permit from Lewis County. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §1.3, 1996]

In the interpretation and application of this chapter, all provisions shall be:

(1) Liberally construed to serve the purpose of this chapter;

(2) Deemed neither to limit nor repeal any other powers under state statute;

(3) Considered adequate mitigation under SEPA unless a proposed use or activity poses an unusual or extraordinary risk to a resource land system. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §1.4, 1996]

The development regulations for resource lands, as set forth in this chapter, shall be reviewed during consideration of the implementing regulations for the Lewis County comprehensive plan, adopted pursuant to Chapter 36.70A RCW. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §1.5, 1996]

Judicial review of any decision made hereunder shall be appealable pursuant to the Land Use Appeals Act, Chapter 36.70C RCW. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §1.7, 1996]

Article II. Reserved

Article III. General Requirements

This chapter classifies and designates resource lands in Lewis County and establishes regulations for the protection of resource lands, human health, and safety. Lewis County shall not grant any permit, license, or other development approval to alter the condition of any land, water, or vegetation, or to construct or to alter any structure or improvement, nor shall any person alter the condition of any land, water, or vegetation, or construct or alter any structure or improvement, for any development proposal regulated by this chapter, except in compliance with the provisions of this chapter. Failure to comply with the provisions of this chapter shall be considered a violation and subject to enforcement procedures. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.1, 1996]

Areas characterized by a particular resource land may also be subject to critical areas regulations due to the overlap of multiple functions of critical areas and resource lands. In the event of any conflict between these regulations and other regulations of the county, the resource lands regulations shall take precedence. No permit granted pursuant to this chapter shall remove the applicant’s obligation to comply in all respects with provision of any federal, state, or local law or regulation. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.2, 1996]

The following activities shall be exempt from the provisions of this chapter:

(1) Existing and ongoing agricultural activities may persist;

(2) Normal and routine maintenance and operation of existing irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, landscape amenities, farm ponds, fish ponds, manure lagoons, and animal water ponds; provided, that such activities do not involve conversion of any resource lands to other than resource land uses;

(3) Maintenance, operation, repair, or replacement of utility facilities and associated rights-of-way, including but not limited to reasonable access roads, and construction of utility facilities reasonably necessary;

(4) Passive recreational uses, sport fishing or hunting, scientific or educational review, or similar minimal-impact, nondevelopment activities;

(5) Site investigative work required by a city, county, state, or federal agency in conjunction with the preparation of a land use application submittal such as surveys, soil logs, percolation tests, and other related activities; except for energy production site investigation work where not otherwise allowed pursuant to Chapter 17.42 LCC, Table 2. In any such activity, resource lands are avoided where possible and minimized where necessary, and disbursed to the extent possible;

(6) Maintenance, operation, reconstruction of or addition to existing roads, streets, and driveways; provided, that reconstruction of any such facilities does not extend outside the previously disturbed area;

(7) Any projects currently under review and “vested” as that term is used in RCW 19.27.095 and 58.17.033 by local, state, or federal agencies prior to official adoption of the ordinance codified in this chapter are exempt from this chapter and will be grandfathered under previous resource lands protection measures; provided, however, “vested properties” shall include any property acquired for development purposes where the following qualifications have been met: (a) the purchase includes lands designated as resource lands pursuant to this chapter; (b) the purchaser can demonstrate through some objective means that the property was acquired for present development purposes (e.g., more than generalized intent, such as a feasibility study, nature of purchaser’s business, or other facts or data); and (c) the earnest money agreement is complete and binding on both parties within 90 days prior to the effective date of the ordinance codified in this chapter; and provided further, such additional vested rights shall be in effect only for the subdivision of such property in fact completed (final plat recorded) within 18 months of the effective date of the ordinance codified in this chapter. [Ord. 1367 (Exh. C), 2025; Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.3, 1996]

An established use or existing structure that was lawfully permitted prior to adoption of the ordinance codified in this chapter, but which is not in compliance with this chapter, shall be processed under this section and not under Chapter 17.155 LCC. The nonconforming activity may continue subject to the following:

(1) Nonconforming uses shall not be expanded or changed in any way that increases the nonconformity without a permit reviewed as a Type III application per Chapter 17.05 LCC or other approval issued pursuant to the provisions of this chapter;

(2) Existing structures shall not be expanded or altered in any manner which will increase the nonconformity without a permit reviewed as a Type III application per Chapter 17.05 LCC or other approval issued pursuant to the provisions of this chapter, except single-family dwellings and accessory structures may be expanded or altered as follows: reconstruction, remodeling, or maintenance of one-family dwellings and accessory structures existing on the effective date of the ordinance codified in this chapter shall be allowed; provided, that a one-time only expansion of the building footprint does not increase that footprint by more than 25 percent;

(3) Activities or Uses Which Are Abandoned. A use discontinued for 60 months shall be presumed abandoned, but such presumption may be rebutted. An abandoned use or structure is allowed to resume only if in compliance with this chapter; and

(4) Nonconforming structures destroyed by fire, explosion, or other casualty may be replaced or restored if reconstruction of the same facility is commenced within two years of such damage. The reconstruction or restoration shall not serve to expand, enlarge, or increase the extent of the nonconformity. [Ord. 1367 (Exh. C), 2025; Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179C §1, 2003; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.8, 1996]

(1) Properties located a certain distance from resource lands shall be provided notice of the resource related activities as follows:

(a) Required Notice Provisions.

(i) NOTICE: The subject property is within or near land designated for long-term commercially significant resource use in which natural resource activities are permitted and encouraged, including a variety of activities that may not be compatible with residential or other types of development for certain periods extending beyond the normal workday and/or work week. In addition to other activities, these may include noise, dust, smoke, visual impacts, and odors. When performed in accordance with best management practices, these resource utilization activities are to be expected and shall not be subject to legal action or public nuisance.

(ii) For mineral resource lands, the notice shall also inform the project proponent that an application may be made for mining-related activities, including mining, extraction, washing, crushing, stockpiling, blasting, transporting, and recycling of minerals.

(b) For building or development permits, this notice shall be provided as a condition of permit approval.

(c) Where the approval is a subdivision or binding site plan, the notice shall be recorded on the face of the plat.

(2) This notice shall be provided for projects on lands within 1,320 feet of designated resources lands. [Ord. 1269 §14, 2016]

The following nonregulatory incentives shall apply to all resource lands:

(1) Assessment Relief.

(a) The Lewis County assessor shall consider the resource lands regulations contained in this chapter when determining the fair market value of land.

(b) Any owner of a resource land who has dedicated a conservation easement to or entered into a perpetual conservation restriction with a department of the local, state, or federal government or to a nonprofit organization to permanently control some or all of the uses and activities within this area may request that the Lewis County assessor reevaluate that specific area with those restrictions.

(c) The administrator shall notify the assessor’s office of any application of this chapter which results in building restrictions on a particular site.

(2) Open Space. Subject to the criteria established by law, any person who owns a resource land area as identified by this chapter may apply for current use assessment pursuant to Chapter 84.34 RCW. The Open Space Tax Act allows Lewis County to designate lands which should be taxed at their current use value. The county has programs for agricultural lands, small forest lands less than 20 acres in size, and other open spaces. Lewis County has adopted a public benefit rating system, which classifies properties on the basis of their relative importance of natural and cultural resources, the availability of public access, and the presence of a conservation easement. These features are given a point value, and the total point value determines the property tax reduction. Lands with an important habitat or species would commonly qualify for this voluntary program. Applications are approved by the board of county commissioners following a public hearing.

(3) Conservation Easement.

(a) Any person who owns an identified resource land as defined by this chapter may offer a conservation easement over that portion of the property designated a resource land naming the county or its qualified designee, under RCW 64.04.130, as the beneficiary of the easement. The purpose of the conservation easement shall be to protect, preserve, maintain, restore, limit the future use of, or conserve for open space purposes the land designated as resource lands, in accordance with RCW 64.04.130. Details governing easement restrictions and conditions of acceptance shall be negotiated between property owners and the county. Acceptance of such an easement and the consideration therefor, if any, shall be discretionary with the county and subject to the priorities for and availability of funds.

(b) The administrator may attach such additional conditions of acceptance as deemed necessary to assure the preservation and protection of the affected wetlands and buffers within conservation easements to assure compliance with the purposes and requirements of this chapter.

(c) The responsibility for maintaining conservation easements shall be held by the overlying lot owner(s) or other appropriate entity as approved by the administrator.

(d) Lewis County may establish appropriate processing fees for such conservation easements.

(4) Development Rights Transfer and Acquisition. Lewis County shall adopt a development rights transfer and/or acquisition program pertaining to development rights on designated resource lands by September, 1998. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.10, 1996]

This chapter is a written policy of Lewis County enforceable through the State Environmental Policy Act, Chapter 43.21C RCW and specifically RCW 43.21C.065. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.11, 1996]

Should the Growth Management Act (Chapter 36.70A RCW) or the implementing regulations (Chapter 360-190 WAC) be challenged or modified by a court of competent jurisdiction or modified by the Legislature in any way affecting this chapter, this chapter shall be brought before the board of county commissioners, not less than 30 days after such action is final, to determine what, if any, changes may be required by reason of such action. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.12, 1996]

Unfunded costs incurred by the county or its citizens which are properly chargeable to the state or state agencies shall be billed to such agencies consistent with applicable rules and regulations for such cost recovery. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §3.13, 1996]

Article IV. Forest Resource Lands

Long-term commercially significant forest resource lands of Lewis County are classified according to the following:

(1) Private Forest Land Grades of the Washington State Department of Revenue (WAC 458-40-530).

(a) The land grade system incorporates consideration of growing capacity, productivity, and soil composition of the land. Forest land 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 predominantly higher grades need not preclude designation of forest land.

(b) The Washington State Department of Community, Trade and Economic Development also recommends that each county determine which land grades constitute forest land of long-term commercial significance, based on local and regional physical, biological, economic, and land use considerations.

(c) The following table is a cross reference of tree species, growth potential, and corresponding land grades on a 50-year basis:

*Land grade 1 = highest; land grade 7 = lowest

(d) The predominant species growing in Lewis County is Douglas fir. Most of Lewis County is composed of Land Grade 2 and Land Grade 3.

(e) A predominance of Forest Land Grade 2 and Forest Land Grade 3 shall be required for designation as forest land of long-term commercial significance.

(2) Minimum Block Size. A minimum block size of 5,000 contiguous acres managed as forest lands. These blocks consist of predominantly large parcels and can be in multiple ownerships.

(3) Property Tax Classification. Property in the block is assessed or eligible to be assessed as open space or forest land pursuant to Chapter 84.33 or 84.34 RCW.

(4) Availability of Public Services Conducive to the Conversion of Forest Land. The property is located outside a designated urban growth area (UGA).

(5) Proximity of Forest Land to Urban and Suburban Areas and Rural Settlements. Forest lands of long-term commercial significance shall be located outside the urban and suburban areas and rural settlements. In addition to being located outside the UGAs, long-term forest lands should be far enough from urban areas that land use conflicts are minimized.

(6) Local Economic Conditions Which Affect the Ability to Manage Timber Lands for Long-Term Commercial Production. Economic conditions should be conducive to long-term timber management. In Lewis County, unfavorable economic conditions include locations with high administrative costs due to complaints from nearby landowners, locations requiring extensive security control efforts, and locations in which allowable forest practices such as burning and chemical applications will significantly interfere with other permitted land uses. Favorable economic conditions include Land Grade 2 and Land Grade 3 forest soils, which provide (in conjunction with large parcel sizes) the growth potential to manage timber lands for long-term commercial production.

(7) History of Land Development Permits Issued Nearby. For Lewis County, this means that recent residential development is an indicator of a pattern or direction of growth that may be encroaching on the forest land. The above criteria are applied throughout unincorporated Lewis County to designate those forest lands of long-term commercial significance. Those lands that currently meet the criteria are shown on map entitled Lewis County Forest Lands, March 1996. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §4.1, 1996]

Lands of Lewis County meeting the classification criteria for forest resource lands are hereby designated as forest resource lands in the following categories:

(1) Forest Land of Long-Term Commercial Significance. Primary forest lands are those forest lands meeting the classification criteria within the minimum blocks of 5,000 contiguous acres and all federally owned lands managed for their forest resources.

(2) Forest Land of Local Importance. Forest lands of local importance are those forest lands meeting the criteria of LCC 17.30.420(1), (3), (4), (6) and (7) which fall outside a 5,000-contiguous-acre block and meet the following criteria:

(a) Formal Designation (“Opt-In”). Forest lands of local importance shall only be designated by the board of county commissioners upon a petition for such designation by the landowner pursuant to the requirements of LCC 17.30.560(2).

(b) Minimum Acreage. Forest lands of local importance shall have a minimum parcel size of 20 acres. However, smaller parcel sizes shall be permitted for designation upon a showing of profitability in the form of a report from a qualified forester to provide a factual basis for designation as a forest land of local importance.

(c) Minimum Period for Commitment to Designation. The landowner petitioning for designation as a forest land of local importance shall be required to commit the property to remain in that designation for 10 years. The designation may be renewed by the landowner at the end of the 10-year period; provided, that renewal of the designation shall not be considered an amendment to the zoning regulations.

(d) Current Forest Land Use. The property is in open space or forest land classification pursuant to Chapter 84.33 or 84.34 RCW. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179C §1, 2003; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §4.2, 1996]

The intent and purpose of this section is to maintain and enhance resource-based industries, encourage the conservation of productive forest lands and discourage incompatible uses. Nothing in this section shall be construed in a manner inconsistent with the Washington State Forest Practices Act. [Ord. 1367 (Exh. C), 2025; Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §4.3, 1996]

See Chapter 17.42 LCC, Table 2, Land Use Summary. [Ord. 1367 (Exh. C), 2025; Ord. 1274 §2, 2017; Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179M §1, 2007; Ord. 1179C §1, 2003; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §4.3(A), 1996]

The minimum lot area for any new subdivision, short subdivision, large lot subdivision or exempt segregation of property shall be as follows, except for parcels to be used for uses and activities provided under LCC 17.30.440 through 17.30.470:

(1) Primary Forest Land. The minimum lot area for subdivision of primary forest lands shall be 80 acres.

(2) Forest Land of Local Importance. The minimum lot area for subdivision of forest lands of local importance shall be 20 acres.

(3) Subdivision as an Incidental Use. A residential subdivision of land for sale or lease within primary or local forest lands, whether lots are over or under five acres in size, may be approved under the following circumstances:

(a) The total density, including existing dwellings, is not greater than one unit per 10 acres for resource lands and one unit per 20 acres for wetlands and areas mapped with hydric soils, steep slopes and flood hazard areas.

(b) Adequate water and provisions for septic capacity are in fact present.

(c) The project affects none of the prime soils on the contiguous holdings at the time of the adoption of this chapter, including all roads and accessory uses to serve the development; provided, that prime lands previously converted to nonforestry uses are not considered prime forest lands for purposes of this section.

(d) The plat shall set aside the balance of the parcel in a designated forest tract.

(e) The plat shall contain the note included in LCC 17.30.370. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179M §1, 2007; Ord. 1179C §1, 2003; Ord. 1179, 2002; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §4.4, 1996]

(1) Within Lands Adjacent to or Abutting Primary Forest Resource Lands. All structures shall maintain a minimum setback of 150 feet from property lines, except for structures not requiring building permits, and 200 feet for all wells, and uses and activities provided under LCC 17.30.440 through 17.30.470; provided, however, the administrator may reduce the structure’s setback where:

(a) It is not reasonable to accomplish the setback given the topography, soils, or shape of the site.

(b) The owner requesting the administrative variance records a forestry easement for the benefit of the abutting primary forest resource lands, granting a right to all normal and customary forestry practices in accordance with best management practices.

(2) Within Land Adjacent to or Abutting Forest Resource Lands of Local Importance. All structures shall maintain a minimum setback of 150 feet from property lines, except for structures not requiring building permits, and 100 feet for all wells, and uses and activities provided under LCC 17.30.440 through

17.30.470; provided, however, that the 150-foot resource lands setback shall not be required where the owner of lands adjacent to or abutting forest lands of local importance records a forestry easement for the benefit of the abutting forest resource lands of local importance, granting a right to all normal and customary forestry practices in accordance with best management practices. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179M §1, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §4.5(A), 1996; Ord. 1151A, 1997]

“Farmland of local importance” is an overlay district in which property owners who wish to protect large unbroken tracts of land may create an overlay zone in the RDD underlying districts that limits minimum lot size to large parcels and protects and encourages the preservation of larger farms and farm forests where conflicts may arise between these activities and other forms of development allowed in the underlying zones.

The designation of farmlands of local importance is applied to those agricultural lands voluntarily nominated by the landowner which are not designated commercial farmland and meet the following criteria:

(1) Formal Designation (“Opt-In”). Farmlands of local importance shall only be designated by the board of county commissioners upon a voluntary petition for such designation by the landowner pursuant to the requirements of LCC 17.30.670. Such applications shall be processed as a Type V amendment to the county comprehensive plan and development regulations.

(2) Minimum Acreage. There is no minimum acreage requirement. Farmlands of local importance shall be designated upon a showing that the property meets the Consolidated Farm Services Agency, USDA, definition of commercial agriculture.

(3) Minimum Period for Commitment to Designation. The landowner petitioning for designation as a farmland of local importance shall be required to commit the property to remain in that designation for 10 years. The designation may be renewed by the landowner at the end of the 10-year period; provided, that renewal of the designation shall not be considered an amendment to the comprehensive plan or zoning regulations.

(4) Current Agricultural Land Use. The property is currently devoted to agricultural activities. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1179R §1, 2007; Ord. 1179C §1, 2003; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §5.3, 1996. Formerly 17.30.590]

(1) This section shall apply to all lots, tracts, or parcels on designated agricultural resource land located within the jurisdiction of Lewis County. The approximate location and extent of farmlands of long-term commercial significance shall be displayed on assessor’s maps marked with significant agricultural lands on file at Lewis County and in the database of the Lewis County Geographic Information System.

(2) In the event of a conflict between the information shown on the maps referred to above and the database and information shown as a result of field investigation, the latter shall prevail.

(3) In the event any farmland of long-term commercial significance shown on the maps referenced above and the database are in conflict with the criteria of this chapter the criteria of this chapter shall prevail. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1151 §5.4, 1996. Formerly 17.30.600]

(1) This section is intended to provide relief for property owners in ARL where prime soils, as listed in the comprehensive plan, do not underlie the entire parcel. The special use process (Chapter 17.158 LCC) for residential, recreational, and other nonresource uses shall be used to determine if, and under what conditions, such uses shall be permitted. [Ord. 1269 §14, 2016; Ord. 1197 §2, 2007]

(1) Property owners who believe a parcel has been included in agricultural resource land in error may request redesignation of that parcel as a Type V application per Chapter 17.05 LCC.

(2) Property owners who claim a parcel was included in agricultural resource land in error due to incorrect mapping of prime soils, as listed in the land use element of the comprehensive plan, shall provide a written report by a certified soils scientist documenting the actual soils conditions on the parcel. The application shall be considered a Type V application per Chapter 17.05 LCC.

(3) Property owners who claim a parcel was included in agricultural resource land in error because soils on the parcel are classified by the National Resources Conservation Service as “prime farmland if drained” and the soils are not drained; or “prime farmland if drained and either protected from flooding or not frequently flooded during the growing season” and the soils are not drained and are not protected from flooding or are subject to flooding during the growing season; or “prime farmland if irrigated” and the parcel is not irrigated due to lack of necessary water rights shall provide a written declaration documenting the drainage or irrigation status of the soils on the parcel. The reclassification will be considered a Type V application per Chapter 17.05 LCC.

(4) Property owners who claim a parcel was included in agricultural resource land in error due to an incorrect assessment of the presence of a commercial, non-soil-dependent agricultural use shall provide a written declaration documenting the absence of such use thereby rendering the parcel no longer devoted to or capable of long-term commercial agriculture. The reclassification will be considered a Type V application per Chapter 17.05 LCC. [Ord. 1269 §14, 2016; Ord. 1207 §2 (Exh. D), 2009; Ord. 1197 §2, 2007]

(a) Avoiding the adverse impact altogether by not taking a certain action or parts of an action, or by moving the action.

(b) Minimizing adverse impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology and engineering, 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 the action.

(e) Compensating for the adverse impact by replacing, enhancing, or providing similar substitute resources or environments, monitoring any adverse impact and mitigation, and taking appropriate corrective or adaptive management measures.

(f) Monitoring the impact and taking appropriate corrective measures.

(3) The mitigation of individual projects may include a combination of the above measures as needed to achieve the most effective protection or compensatory mitigation of the critical area functions and values.

(4) On-Site Versus Off-Site Mitigation.

(a) To assure that a mitigation report relieves the direct impacts of an action, on-site mitigation is preferred over off-site mitigation.

(b) Off-site mitigation is only allowed:

(i) Where appropriate, adequate on-site mitigation is not reasonable or desirable to achieve; or

(ii) Where off-site mitigation better achieves the purposes of this chapter. [Ord. 1284 §4, 2018]

(1) Monitoring Required. The administrator shall require applicants to monitor mitigation projects to ensure that the performance standards are satisfactorily met. Monitoring reports shall be submitted to the county in accordance with the monitoring timetables articulated in the mitigation plan or geotechnical report, typically over a period of five to 10 years.

(a) Monitoring should occur for at least five years from the date of plant installation and ten years where woody vegetation (such as in forested or shrub wetlands) is the intended result.

(c) The administrator may waive the monitoring requirement for structural improvements, such as retaining walls, foundations or bulkheads, when located near critical areas or their buffers.

(2) Schedule for Monitoring. Monitoring reports for mitigation projects shall be submitted every year, unless an alternative schedule is approved. A potential schedule for a 10-year monitoring period includes the submittal of reports in years one, two, three, five, seven and 10.

(3) Monitoring Report. Monitoring reports shall include sufficient information to document and assess the degree of mitigation success or failure as defined by the performance standards articulated in the approved mitigation plan or geotechnical report. Information to be provided in monitoring reports shall include the following:

(a) Methods used to document compliance with the performance standards;

(b) Measurements of the percent survival of planted material, plant cover, stem density, presence of invasive species, and/or other attributes;

(c) For sites that involve wetland creation, re-establishment or rehabilitation, hydrologic observations of soil saturation/inundation as needed to demonstrate that a site meets the wetland hydrology criterion;

(d) Representative photographs of the site;

(e) A written summary of the overall site conditions and recommendations for maintenance actions if needed; and

(f) Other information that the administrator deems necessary to ensure the success of the mitigation.

(4) Projects that fail to meet monitoring objectives. For projects that fail to address the performance standards identified in the mitigation plan or geotechnical report, the administrator may (among other options):

(a) Require corrective mitigation measures; and/or

(b) Extend the required monitoring period.

(5) The permanent protection of mitigation areas or facilities shall be achieved through deed restriction and/or other protective covenant. [Ord. 1284 §4, 2018]

(1) A project applicant shall demonstrate sufficient capability to implement the mitigation project, monitor the site, and make corrections if the mitigation fails to meet projected goals. A surety to ensure the success of the mitigation may be required:

(a) When deemed necessary by the administrator, the applicant shall post a mitigation surety in the amount of 125 percent of the estimated cost of the uncompleted mitigation actions. The value of the surety shall be based on an itemized cost estimate of the proposed mitigation activities, including clearing and grading, plant materials, plant installation, irrigation, weed management, monitoring, and other costs.

(b) The surety shall be in the form of an assignment of funds or other means approved by the administrator.

(c) The surety shall remain in effect until the administrator determines, in writing, that the standards that have been bonded for have been met. The surety shall generally be held by the county for a period of five years to ensure that the required mitigation has been fully implemented and demonstrated to function. The surety may be held for longer periods when necessary.

(d) After the initial completion of the mitigation, a surety for the construction of the mitigation may be reduced to an amount not to exceed the cost of the monitoring plus not less than 25 percent of the construction cost.

(e) The depletion, failure, or collection of surety funds shall not discharge the obligation of an applicant or violator to complete the required mitigation, maintenance, or monitoring.

(f) Public development proposals may be relieved from having to comply with the bonding requirements of this section if the agency demonstrates that: public funds have been committed to the mitigation, maintenance, or monitoring; and the funds will be available throughout the monitoring period.

(2) Default. Any failure to satisfy the critical area requirements established by law or condition, including but not limited to the failure to provide a monitoring report within 30 days of its due date or the failure to comply with other provisions of an approved mitigation plan, shall constitute a default of the surety. The county may demand the payment of the financial guarantee or pursue some other remedy that is authorized by the county code or other applicable law. All funds recovered pursuant to this section shall be used to complete the required mitigation. [Ord. 1284 §4, 2018]

(1) Technical analyses, including critical areas assessments, mitigation plans, and geotechnical reports, that are submitted as part of an application shall be completed by a qualified critical area professional as defined in LCC 17.10.170.

(2) Peer Review Allowed. During the course of review, the administrator may retain, at the applicant’s expense, a qualified professional to perform a peer review of the assessment and mitigation reports. The administrator may similarly consult outside agencies with expertise that pertains to the proposal when necessary. [Ord. 1284 §4, 2018]

 Article II. Activities Allowed without a Critical Areas Permit

(1) Activities Allowed without a Lewis County Permit. The activities in subsections (2) through (4) of this section are allowed without the submission of a Lewis County critical areas permit or assessment report; provided, that a critical area assessment report shall be required for the activities when they are not specifically exempted from local review and the actions:

(h) Emergency actions, including those activities necessary to prevent an immediate threat to public health, safety, or welfare, or that pose an immediate risk of damage to private property and that require remedial or preventative action in a time frame too short to allow for compliance with the requirements of this chapter.

(i) Emergency actions that create an impact to a critical area or its buffer shall use reasonable methods to address the emergency. In addition, they must have the least possible impact to the critical area or its buffer. The person or agency undertaking such action shall notify the administrator within 14 working days following commencement of the emergency activity, except for county-wide or regional disasters for which the director shall provide alternative deadlines.

(ii) After the emergency, the person or agency undertaking the action shall fully fund and conduct necessary restoration and/or mitigation for any impacts to the critical area and buffers resulting from the emergency action. The person or agency undertaking the action shall obtain all approvals required for this chapter. Restoration and/or mitigation activities must be initiated within one year of the date of the emergency, and be completed as provided for in this chapter.

Home and garden herbicides, pesticides, and fertilizers may be used to maintain existing landscaping and gardens within critical area buffers, when applied at times and rates specified on the label in accordance with Washington State Department of Agriculture and other applicable regulations. Home and garden herbicides, pesticides, and fertilizers may not be used in wetlands, streams, or other water bodies without the submittal of a critical areas permit.

(3) Permit Exempt Activities - Wetlands and their Buffers. The following activities are additionally allowed within wetlands and their buffers without a critical areas permit, when the activities meet the requirements of subsection (1) of this section:

(a) Drilling for utilities/utility corridors under a buffer with entrance/exit portals located completely outside of the wetland boundary; provided, that the drilling does not interrupt the ground water connection to the wetland or stream or the percolation of the surface water through the soil column. Specific studies shall be submitted by a hydrologist to determine whether the ground water connection to the wetland, or the percolation of surface water through the soil column, will be disturbed.

(b) Stormwater management facilities. A wetland or its buffer can be physically or hydrologically altered to meet the requirements of a low-impact development, runoff treatment or flow control best management practice if all of the following criteria are met:

(vii) Alterations to the structure of the wetland or its soils obtain the necessary permits for the proposal.

(viii) All lost functions and values of the wetland are compensated/replaced.

To determine if a low-impact development best management practice will be feasible at a project site, a site specific characterization by a qualified professional is required. Wetlands may contain features that render low-impact development best management practices infeasible.

(4) Permit Exempt Activities - Buffers Only. The following activities are allowed within critical area buffers without a critical areas permit, when the activities meet the requirements of subsection (1) of this section:

(a) Repair and maintenance of nonconforming uses or structures, when legally established within the buffer; provided, that the activities do not increase the degree of nonconformity for the critical area, or otherwise cause a net loss in the ecological functions of the critical area or buffer. [Ord. 1284 §4, 2018]

Article III. Wetlands

The purposes of this article are to:

(1) Regulate land use to avoid adverse effects on wetlands and maintain the functions and values of wetlands throughout Lewis County.

(2) Protect the beneficial functions performed by wetlands, which include, but are not limited to: providing food, breeding, nesting and/or rearing habitat for fish and wildlife; providing habitat for endangered, threatened and sensitive species; recharging and discharging ground water; contributing to stream flow during low flow periods; stabilizing stream banks and shorelines; storing storm and flood waters to reduce flooding and erosion; and improving water quality through biofiltration, adsorption, and the retention and transformation of sediments, nutrients, and toxicants.

(3) Establish review procedures for development proposals, which are consistent with best available science, in and adjacent to wetlands. [Ord. 1284 §4, 2018]

Compliance with the provisions of this article does not constitute compliance with other federal, state, and local regulations and permit requirements that may be required. The applicant is responsible for complying with those requirements, in addition to the process established in this article. [Ord. 1284 §4, 2018]

(1) Administration of this article shall occur in accordance with Article I of this chapter.

(2) When a project is subject to these requirements and does not fall within the activities listed in Article II of this chapter, the reports in Table 17.38-1 shall be required to review the projects.

(3) State and federal permits may be required even when a wetland is exempt from county requirements. [Ord. 1284 §4, 2018]

(1) Wetlands shall be identified and delineated in accordance with the requirements of RCW 36.70A.175 and LCC 17.38.230.

(2) The administrator may accept a written determination by the U.S. Army Corps of Engineers and the Washington State Department of Ecology (Ecology) that a specific parcel is not a wetland, as long as the determination is consistent with current local, state or federal law. [Ord. 1284 §4, 2018]

(1) Rating. Wetlands shall be identified and rated according to the Washington Department of Ecology wetland rating system, as set forth in the Washington State Wetland Rating System for Western Washington: 2014 Update (Ecology Publication No. 14-06-029, or as revised and approved by Ecology), which contains the definitions and methods for determining whether the criteria below are met.

(a) Category I. Category I wetlands are: (i) wetlands of high conservation value that are identified by scientists of the Washington Natural Heritage Program/DNR; (ii) bogs; (iii) mature and old-growth forested wetlands larger than one acre; or (iv) wetlands that perform many functions well (scoring 23 points or more). The wetlands: (i) represent unique or rare wetland types; (ii) are more sensitive to disturbance than most wetlands; (iii) are relatively undisturbed and contain ecological attributes that are impossible to replace within a human lifetime; or (iv) provide a high level of functions.

(b) Category II. Category II wetlands are: wetlands with a moderately high level of functions (scoring between 20 and 22 points).

(c) Category III. Category III wetlands are: (i) wetlands with a moderate level of functions (scoring between 16 and 19 points); and (ii) can often be adequately replaced with a well-planned mitigation project. Wetlands scoring between 16 and 19 points generally have been disturbed in some way and are often less diverse or more isolated from other natural resources in the landscape than Category II wetlands.

(d) Category IV. Category IV wetlands have the lowest levels of functions (scoring fewer than 16 points) and are often heavily disturbed. These wetlands are often able to be replaced, or in some cases improved. However, experience has shown that replacement cannot be guaranteed in any specific case. The wetlands may provide some important functions, and should be protected to some degree.

(2) Illegal Modifications. Illegal modifications to a wetland made by the applicant or with the applicant’s knowledge shall not change a wetland’s rating. [Ord. 1284 §4, 2018]

Projects proposed in or adjacent to wetlands are required to utilize the mitigation sequence shown in LCC 17.38.080(2). [Ord. 1284 §4, 2018]

(1) The following wetlands may be exempt from the requirement to avoid impacts to wetlands (as defined in the mitigation sequence in LCC 17.38.080(2)(a)). The wetlands may be filled if the remaining actions in the mitigation sequence (LCC 17.38.080(2)(b) through (e)) ensure that no net loss of wetland functions and values will occur from the activity.

(a) All isolated Category IV wetlands less than 4,000 square feet that:

(i) Are not associated with riparian areas or their buffers.

(ii) Are not associated with shorelines of the state or their associated buffers.

(iii) Are not part of a wetland mosaic.

(iv) Do not score six or more points for habitat function based on the 2014 update to the Washington State Wetland Rating System for Western Washington: 2014 Update (Ecology Publication No. 14-06-029, or as revised and approved by Ecology).

(v) Do not contain a federally listed species or their critical habitat, priority habitat or species identified by the Washington Department of Fish and Wildlife, or species of local importance identified in LCC 17.38.420.

(b) Wetlands less than 1,000 square feet that meet the above criteria and do not contain federally listed species or their critical habitat are exempt from the buffer provisions contained in this chapter.

(2) To ensure that no reduction of wetland values and functions occurs as a result of this section, a wetland assessment report and mitigation plan meeting the requirements in LCC 17.38.320 and 17.38.330 must be submitted. [Ord. 1327 §2, 2021; Ord. 1284 §4, 2018]

The use intensities in Table 17.38-2 shall be used in connection with the standards to classify wetlands in LCC 17.38.230 to determine required buffers.

1 Measured as density averaged over a development site, not necessarily an individual lot size.

[Ord. 1284 §4, 2018]

(1) Utilizing the impact levels specified above, the buffer widths in Table 17.38-3 have been established in accordance with best available science.

(a) Buffers.

1 Buffers are 260 feet for eight habitat points and 300 feet for nine habitat points.

(b) Other Protections. Uses with proximity impacts, such as noise, light, glare or other characteristics that may affect wetland ecological functions, may be required to provide greater buffers than indicated, or to provide site design and layout, or operational measures, that reduce project impacts to levels appropriate to the designated buffer. Elements to reduce potential buffer impacts include screening the buffer edge with dense plantings or fencing, and other items. [Ord. 1327 §3, 2021; Ord. 1284 §4, 2018]

Buffer widths may be reduced in the following instances without the submittal of a mitigation plan:

(1) Reduction in Buffer Width by Reducing the Intensity of Land Use Impacts. The widths of buffers recommended for proposed land uses with high-intensity impacts can be reduced to the buffers recommended for moderate-intensity impacts under the following conditions:

(a) For wetlands that score moderate or high for habitat (six points or more for the habitat functions), the width of the buffer can be reduced if both of the following criteria are met:

(i) A relatively undisturbed, vegetated corridor at least 100 feet wide is protected between the wetland and any other priority habitats as defined by the Washington state Department of Fish and Wildlife. The latest definitions of priority habitats and their locations are available on the WDFW website at: http://wdfw.wa.gov/hab/phshabs.htm. The corridor must be protected for the entire distance between the wetland and the priority habitat by some type of legal protection such as a conservation easement.

(ii) Measures to minimize the impacts of different land uses on wetlands, such as the examples summarized in Table 17.38-4, are applied; provided, that the administrator may approve of alternative impact reduction measures that are demonstrated to have equivalent effectiveness in reducing impacts on wetland functions.

(b) For wetlands that score five or less points for habitat, the buffer width can be reduced to that required for moderate land-use impacts by applying the measures to minimize the impacts of the proposed land uses (see examples in Table 17.38-4).

(2) Reductions in Buffer Widths Where Existing Roads or Structures Lie within the Buffer.

(a) The administrator may allow a reduced buffer where a legally established substantial improvement such as a road, railroad, or structure serves to eliminate or greatly reduce the impact of a proposed activity upon a wetland buffer.

(b) Where such a substantial improvement exists, the buffer may be reduced to the critical area edge of the existing substantial improvement.

(c) If a project has the potential to impact the functions of a wetland or its buffer, even though such a substantial improvement exists, the administrator shall require the applicant to submit a wetland assessment report to ensure that no net loss of ecological values and functions occurs. A mitigation plan may be required.

(d) As used within this section only, substantial improvements shall include developed public infrastructure such as roads and railroads, and private improvements such as homes, commercial structures, and paved parking lots. Substantial improvements shall not include paved trails, sidewalks, private driveways, resident parking areas, and accessory buildings that do not require a building permit.

(3) Common Line Buffers.

(a) For legal lots of record that: were created prior to July 26, 1999; are smaller than two acres in size; are proposed for residential development; and are bound by neighboring home sites, the required buffer may be reduced to the buffers for neighboring properties when the proposal incorporates the measures in Table 17.38-4, as well as other appropriate mechanisms, to provide compensatory mitigation for the impacts to wetland functions and values.

(i) Existing Residences on Both Sides. Where existing residences are within 300 feet of both sides of the proposed residence, the buffer may be drawn as a common line calculated by the average of both adjacent residential setbacks from the wetland.

(ii) Existing Residence on One Side. When a site only has one existing residence adjacent to the proposed development, the common line buffer may be the average of the required buffer for the wetland and the average setback of the adjacent residence from the wetland.

(b) A common line buffer reduction based on neighboring development shall require an analysis by a qualified professional that evaluates the existing environmental conditions and how the reduced buffer width would affect existing wetland functions when compared to the standard buffer.

(c) Existing wetland functions and values must be protected by the reduced buffer and the proposed mitigation measures. [Ord. 1327 §4, 2021; Ord. 1284 §4, 2018]

An applicant may request to average the width of a wetland buffer, thereby reducing the width of a portion of the buffer and increasing the width of another portion, if all of the following requirements are met:

(1) Averaging to improve wetland protection may be permitted when all of the following conditions are met:

(a) The wetland has significant differences in characteristics that affect its habitat functions, such as a wetland with a forested component adjacent to a degraded emergent component, or a “dual-rated” wetland with a Category I area adjacent to a lower rated area.

(b) The buffer is increased adjacent to the higher-functioning habitat area or more sensitive portion of the wetland and decreased adjacent to the lower functioning or less sensitive portion.

(2) Averaging to allow the reasonable use of a parcel may be permitted when all of the following are met:

(a) Buffer averaging is necessary to accommodate existing conditions, such as topography, existing roads, public facilities, or similar features that prevent reasonable development in compliance with standard buffers.

(b) There are no feasible site design alternatives that could be accomplished without buffer averaging.

(c) Averaging will not impair or reduce the habitat, water quality purification and enhancement, stormwater detention, ground water recharge, shoreline protection, erosion protection, and other functions of the wetland and buffer as demonstrated by a report from a qualified wetland professional.

(3) Buffer averaging must meet the following criteria:

(a) The total area of the buffer on the subject property is not less than the buffer that would be required if averaging was not allowed, and all increases to the buffer dimensions from averaging are generally parallel to the wetland boundary (to avoid creating buffer panhandles).

(b) No part of the width of the buffer is less than 75 percent of the required width. [Ord. 1284 §4, 2018]

(1) Wetland Mitigation. The alteration of wetlands shall require the creation, restoration, or enhancement of wetlands to provide equivalent or greater functions and values. In order to address the risk and time lag associated with the creation, restoration, or enhancement of wetlands, the following acreage replacement ratios shall be required, except as provided for in subsection (5) of this section. The listed ratios assume that the replacement wetland will be similar in type and structure to the wetland being altered.

*Ratio is the replacement area: impact area.

(2) Buffer Mitigation. Impacts to wetland buffers shall be mitigated at a minimum 1:1 ratio. Compensatory buffer mitigation shall replace the buffer functions lost from development.

(3) Increasing or Decreasing Replacement Ratios. Mitigation ratios may be increased or decreased based on the following circumstances:

(a) The degree of uncertainty as to the probable success of the proposed mitigation;

(b) The period of time between the alteration of the wetland or buffer and the replacement of lost functions and values; and

(c) The projected gains or losses in functions and values; provided, that the findings of special studies coordinated with agencies with expertise demonstrate that no loss of wetland functions or values will result from a reduced ratio.

(4) Replacement of Functions and Values. In lieu of mitigation based on land area, as provided above, an applicant may alternatively propose mitigation based on the credit/debit methodology established by the Washington Department of Ecology. Such a proposal shall follow the process and provide the details established in Calculating Credits and Debits for Compensatory Mitigation in Wetlands of Western Washington dated March 2012 and note:

(a) The degree of uncertainty as to the probable success of the proposed mitigation;

(b) The period of time between the alteration of the wetland or buffer and the replacement of lost functions and values;

(c) Projected gains or losses in functions and values; provided, that findings of special studies, coordinated with agencies with expertise, demonstrate that no loss of wetland functions or values will result from the proposal.

(5) Standards for Mitigation. Mitigation projects shall meet the following requirements:

(a) Location. Compensatory mitigation actions shall generally be conducted within the same sub-drainage basin and on the site of the alteration except when the applicant can demonstrate that off-site mitigation is ecologically preferable.

(b) Allowed Mitigation Approaches. The following wetland mitigation approaches are allowed:

(i) Wetland Mitigation Banks. Credits from a certified wetland mitigation bank may be used to compensate for wetland and buffer impacts that are located within the service area specified in the mitigation bank instrument. Standards for the creation of a wetland mitigation bank are available in Chapter 173-700 WAC.

(ii) Permittee-Responsible Mitigation. Permittee-responsible mitigation may occur at the site of the permitted impacts or at an off-site location within the same watershed. With permittee-responsible mitigation, the permittee performs the mitigation after the permit is issued and is ultimately responsible for the implementation, monitoring and success of the mitigation.

(iii) Additional mitigation approaches (such as in-lieu fee mitigation) may also be approved, so long as: the administrator determines that the approach ensures that no net loss of wetland functions and values will occur; an appropriate organizational entity will implement the mitigation; and a monitoring plan will be provided to show the success of the mitigation. Approved in-lieu-fee program credits may be used for wetland and buffer impacts that are situated within a service area specified within an approved in-lieu-fee instrument. Project applicants should contact the U.S. Army Corps of Engineers, Seattle District, for more information. [Ord. 1284 §4, 2018]

(1) Waters of the state as defined in RCW 77.55.011 and 90.56.010, but not including shorelines of the state as defined in RCW 90.58.010.

(2) Naturally occurring ponds under 20 acres and their submerged aquatic beds that provide fish or wildlife habitat.

(3) Lakes, ponds, streams, and rivers planted with game fish by a governmental or tribal entity. [Ord. 1284 §4, 2018]

(1) Streams and lakes are classified in accordance with the Washington State Department of Natural Resources (DNR) as provided in WAC 222-16-030, with the following revisions:

(a) “Type S water” means all waters identified as shorelines of the state under Chapter 90.58 RCW and the rules promulgated pursuant to Chapter 90.58 RCW, including periodically inundated areas of their associated wetlands. Type S waters are regulated entirely by the Lewis County shoreline master program.

(b) “Type F water” means segments of natural waters other than Type S waters, as defined by the ordinary high water mark and periodically inundated areas of their associated wetlands, except as regulated by LCC 17.38.220, or within lakes, ponds, or impoundments having a surface area of one-half acre or greater at seasonal low water and which in any case contain fish habitat, as well as riverine ponds, wall-based channels, and other channel features that are used by fish for off-channel habitat.

(c) “Type Np water” means all segments of natural waters within defined channels that are perennial nonfish habitat. Perennial streams are waters that do not go dry at any time during a year of normal rainfall. However, for the purpose of water typing, Type Np waters include the intermittent dry portions of the perennial channel below the uppermost point of perennial flow.

(d) “Type Ns water” means all segments of natural waters within defined channels that are not Type S, F, or Np waters. These are seasonal, nonfish habitat streams in which surface flow is not present for at least some portion of a year of normal rainfall and are not located downstream from any stream reach that is a Type Np water. Ns waters must be physically connected by an aboveground channel system to Type S, F, or Np waters.

(2) Classification. Stream typing data from the Washington State Department of Natural Resources (DNR) is utilized to show the approximate location of streams and their types.

(a) Where a stream is shown on the DNR mapping, but no stream is present or the location is in error, the administrator may waive the requirements for additional studies after a qualified professional prepares a site investigation that details the existing stream conditions.

(b) Where a question about the correct stream type exists, Lewis County may consult with WDFW about the appropriate stream classification. [Ord. 1284 §4, 2018]

(1) Definitions and maps of wildlife habitat areas are based on the following documents:

(a) The United States Endangered Species Act of 1973, and species and critical habitat designed thereunder;

(b) The 1999 Washington Department of Fish and Wildlife Priority Habitats and Species List;

(c) The 1997 Management Recommendations for Washington’s Priority Habitats;

(d) The list of best available science references maintained by the responsible official; and

(e) Associated GIS data files maintained by Lewis County GIS department.

(2) Updated as Needed. Maps supporting this chapter may be updated and/or reevaluated as new information comes available. [Ord. 1284 §4, 2018]

(1) Determining Site-Specific Applicability. In the event of inconsistencies, official habitat area definitions shall prevail over countywide maps in determining applicability of this chapter. The county shall follow the recommendations of WDFW in the interpretation of site-specific conditions as they relate to the definition of priority habitat and species. [Ord. 1284 §4, 2018]

(a) Development of geologically hazardous areas and their required buffers shall follow the mitigation sequence in LCC 17.38.080(2).

(b) Where no reasonable alternative to the alteration of a potentially hazardous area is available, the administrator may allow the development of the area when a geotechnical report, as described in LCC 17.38.710, is submitted by a qualified professional.

(c) When a geotechnical report has been submitted, the administrator may only allow the alteration when the report shows:

(i) The site is stable under existing conditions based on a plane of failure analysis with a factor of safety of 1.5 under seismic conditions for unconsolidated deposits or other factor of safety relevant to the type of development and hazard.

(ii) The alteration of vegetation will not increase the probability of the failure of the geologically hazardous area.

(iii) The proposed grading, excavation and structures will not increase the probability of the failure of the geologically hazardous area, and the construction of facilities to reduce risk, such as drainage systems, are effective in the absence of mechanical systems and ongoing long-term maintenance.

(iv) The development will incorporate measures to control additional erosion and deposition downslope or downstream, and the proposed measures to control the erosion are feasible.

(v) The development will not increase the risk of geologic failure on the site or adjacent properties.

(vi) The alteration will not adversely impact other critical areas or their associated buffers, such as wetlands, wildlife habitat areas, frequently flooded areas and critical aquifer recharge areas.

(d) The alteration may be approved, approved with conditions, or denied based on the administrator’s evaluation of the suitability of the geotechnical report and proposed mitigation measures to protect life, safety, and stability on the subject and nearby properties.

(2) Standards for Seismic Hazard Areas. Developments that are proposed within seismic hazard areas shall meet the applicable provisions of the International Building Code.

(3) Standards for Alluvial Fan Hazard Areas. Development is not permitted within alluvial fan hazard areas, beyond what is allowed in the reasonable use provisions of this code.

(4) Standards for Critical Facilities. Critical facilities, as defined under Chapter 17.10 LCC (Definitions), shall only be allowed within seismic and volcanic hazard areas; provided, that no critical facilities shall be allowed within one-quarter mile of an active fault or trench. When an application for a critical facility is proposed within a seismic or volcanic hazard area, the proposal shall articulate the planned strategies to evacuate individuals within the facility, or ensure continuity of operations, in the case of a natural hazard.

(5) Verification of Completion of Mitigation. Upon the completion of a project, a qualified professional shall verify that any mitigation or safety measures associated with a geotechnical report have been properly implemented in accordance with LCC 17.38.090. Depending on the nature of the mitigation (i.e., structural versus planting (of vegetation) or small or large scale improvements), the administrator may waive the five-year monitoring time frame that is specified within that section.

Article V-A. Classification of Hazard Areas

Erosion hazard areas are those areas that have severe or very severe erosion potential as detailed in the soil descriptions contained in the Web Soil Survey for Lewis County, Washington, Soil Survey Staff, Natural Resources Conservation Service, United States Department of Agriculture. Available online at:

https://websoilsurvey.sc.egov.usda.gov/

Accessed December 1, 2016. [Ord. 1284 §4, 2018]

(1) Classification of Steep Slope Hazard Areas. Steep slope hazard areas are areas where there is not a mapped or designated landslide hazard, but where there are steep slopes equal to or greater than a 35 percent slope with a vertical relief of 10 or more feet. Steep slopes which are less than 10 feet in vertical height and are not part of a larger steep slope system, and steep slopes created through previous legal grading activity, are not regulated steep slope hazard areas. Presence of a steep slope suggests potential slope stability problems.

(2) Classification of Landslide Hazard Areas. Landslide hazard areas are those areas meeting any of the following criteria:

(a) Areas subject to previous slope failures, including areas of unstable old or recent landslides;

(b) Areas with all of the following characteristics:

(i) A slope greater than 15 percent;

(ii) Hillsides intersecting geologic contacts with a relatively permeable sediment overlying a relatively impermeable sediment or bedrock; and

(iii) Springs or ground water seepage;

(c) Slopes that are parallel or sub-parallel to planes of weakness (such as bedding planes, joint systems, and fault planes) in subsurface materials;

(d) Slopes having gradients greater than 80 percent subject to rockfall during seismic shaking;

(e) Areas potentially unstable as a result of rapid stream incision and streambank erosion or undercutting;

(f) Areas located in a canyon, on an alluvial fan, or presently or potentially subject to inundation by debris flows or catastrophic flooding.

(3) Mapped Landslide Hazard Areas. Landslide hazard areas include the following mapped sources:

(a) Areas mapped as “unstable,” “landslides,” and “old landslides” in the Slope Stability Study of the Centralia-Chehalis Area, Lewis County, Washington, by Allen J. Fiksdal, Department of Natural Resources, Division of Geology and Earth Resources, 1978.

Such a study shall be developed in accordance with best available science and investigate areas upstream and downstream of the review site that could influence the migration of the channel and the channel migration corridor. [Ord. 1284 §4, 2018]

(1) Classification of Alluvial Fan Hazards. Alluvial fan hazard areas are low, outspread, relatively flat to gently sloping deposits of sediments and organic debris, shaped like an open fan or segment of a cone, deposited by streams or debris flows where they issue from narrow, steep valleys upon a plain or broad valley or wherever the gradient of the stream suddenly decreases.

(2) A single mapped alluvial fan hazard area is depicted in Geomorphic Evaluation and Channel Migration Zone Analysis Addendum: Cowlitz River, near Packwood and Randle, Lewis County, Washington, produced by GeoEngineers for the Lewis County public works department, 2009, 76 pages.

 Article VII. Frequently Flooded Areas

The purpose of this article is to help the public and private sectors avoid losses due to flood conditions in specific areas. [Ord. 1284 §4, 2018]

For the purposes of this chapter, frequently flooded areas within Lewis County shall be classified using the following criteria: frequently flooded areas shall be those lands, identified by the Federal Emergency Management Agency, as falling within the 100-year frequency floodplain in the Flood Insurance Study for Lewis County, Washington, Unincorporated Areas, the most current version thereof, with accompanying flood insurance rate maps and floodway maps or the best available information based on past flood records or special studies. [Ord. 1284 §4, 2018]

Lands within Lewis County meeting the classification criteria for frequently flooded areas are hereby designated and subject to the standards and requirements set forth below. [Ord. 1284 §4, 2018]

Development within designated frequently flooded areas shall be in compliance with Chapter 15.35 LCC, as now or hereafter amended, and the Lewis County shoreline master program where applicable, as now or hereafter amended. [Ord. 1327 §5, 2021; Ord. 1284 §4, 2018]

 Article VIII. Miscellaneous Provisions

An established use or existing structure that was lawfully permitted prior to adoption of the ordinance codified in this chapter, but which is not in compliance with this chapter, shall be processed under this article and not under Chapter 17.155 LCC. The nonconforming activity may continue subject to the following:

(1) Nonconforming uses shall not be expanded or changed in any way that increases the nonconformity without a permit or other approval issued pursuant to the provisions of this chapter.

(2) Existing structures shall not be expanded or altered in any manner which will increase the nonconformity without a permit or other approval that is issued pursuant to the provisions of this chapter.

(3) Activities or Uses Which Are Abandoned. Uses discontinued for 36 months shall be presumed to be abandoned, though such presumption may be rebutted. Abandoned uses or structures are allowed to resume only if in compliance with this chapter.

(4) Nonconforming structures destroyed by fire, explosion, or other disaster may be replaced or restored if reconstruction of the same facility is commenced within 24 months of such damage. Reconstruction or restoration shall not serve to expand, enlarge, or increase the extent of the nonconformity, except as provided in subsection (2) of this section. [Ord. 1284 §4, 2018]

Permit applicants who are unable to comply with the specific standards of this chapter may seek approval pursuant to the reasonable use or variance standards and procedures provided for in this section. Approval may be granted if the proponent demonstrates that the application of the standards of this chapter would constitute an extraordinary hardship for the proposal, and the following reasonable use or variance standards are met:

(1) Reasonable Use Standard. This chapter is not intended to preclude all reasonable economic use of a property. If the application of this chapter would deny all reasonable economic use of a subject property, including agricultural use, a use or development shall be allowed if the applicant submits a report, prepared by a qualified professional, that demonstrates the following to the satisfaction of the administrator:

(a) That there is no portion of the site where the provisions of this chapter allow reasonable economic use, including agricultural use or the continuation of legal nonconforming uses;

(b) That there is no feasible alternative to the proposed activities, including locating the activity on a contiguous parcel that has been under the ownership or control of the applicant since the effective date of the ordinance codified in this chapter, changing the use, reducing the density, phasing the project implementation, changing the timing of activities, revising road and lot layout, and/or related site planning considerations, that would allow a reasonable economic use with less adverse impacts to the critical area and its related buffer;

(c) That the proposed activities will result in the minimum feasible alteration or impairment to the critical area’s functional characteristics and existing environment;

(d) That the disturbance of critical areas has been minimized by locating any necessary alteration as far as possible from critical areas and the project employs all reasonable methods to avoid or mitigate adverse effects on critical area functions and values, including maintaining existing topography and hydrology and maintaining or enhancing existing vegetation through site planning including the location of a road or driveway. Disturbances or activities shall be located in a related buffer rather than a critical area to the extent possible;

(e) That the proposed activities will not jeopardize the continued existence of habitats or species listed by the federal or state government as endangered, threatened, or sensitive;

(f) That the proposed activities will not significantly affect the quality of ground or surface water;

(g) That the proposed activities will comply with all federal, state, and local laws and regulations, including those related to sediment control, pollution control, floodplain restrictions, and on-site wastewater disposal;

(h) That any and all alterations to critical areas and their related buffers will be mitigated as required by the provisions of this chapter;

(i) That there will be no injury to nearby public or private property and no significant effect upon the health, safety, or welfare of persons within or outside of the property; and

(j) That the inability to derive reasonable economic use of the property is not the result of deliberate actions by the applicant or prior owners after the effective date of the ordinance codified in this chapter.

(2) Reasonable Use Process.

(a) The director may approve a single-family dwelling, on property that is under one ownership as of the effective date of the ordinance codified in this chapter, as part of Type I permit (per Chapter 17.05 LCC).

(b) Other requests for reasonable use permits shall be processed in accordance with the permit review type for the underlying permit application.

(3) Variance Standards. In cases where the reasonable use criteria do not apply, an individual may seek a variance from the other standards of this chapter. The variance may be approved when an applicant submits a report that has been prepared by a qualified professional and complies with the procedures and criteria in Chapter 17.162 LCC. [Ord. 1284 §4, 2018]

(1) Standards for Wetlands, Fish and Wildlife Habitat Areas, and Geologically Hazardous Areas, Except for Seismic Hazards and Volcanic Hazards.

(a) Land Division. Where a land division is proposed for a site with a critical area and/or its buffer, the development shall be designed to avoid the need to impact the features.

(i) Each lot created through a land division must be sufficiently sized to accommodate all necessary facilities and site amenities required for the property outside of the critical area and required buffers, unless methods to mitigate the impacts to the buffers are identified. Potential facilities and site amenities to consider include, but are not limited to: the location of the well and the buffer for the well, the septic system and required drainfields, the building, and any needed parking facilities.

(ii) Clustering may be used as a means to group development sites away from critical areas and their buffers.

(b) Easements or Tracts. Prior to the final approval of any land division, the part of the critical area and required buffer that is located on the site shall be protected by clearly showing the boundary of the critical area and its buffer and placing a restriction on the use of the area. Critical areas may be:

(i) Noted on the face of a plat with a description of the restriction of the use of the area;

(ii) Covered by a protective easement, or public or private land trust dedication;

(iii) Preserved through an appropriate permanent protective mechanism that provides the same level of permanent protection as designation of a separate tract or tracts as determined by the administrator or hearing examiner.

(2) Standards for Frequently Flooded Areas.

(a) Compliance with Flood Standards. All land divisions in frequently flooded areas shall be designed in accordance with LCC 15.35.230.

(3) Standards for Critical Aquifer Recharge Areas.

(a) All land divisions in critical aquifer recharge areas shall meet the relevant requirements in Article VI of this chapter. [Ord. 1284 §4, 2018]

(1) To protect vegetation and other critical area features, buildings and other structures shall be set back a minimum of 15 feet from the edge of the critical area buffer, or from the edge of a critical area where no buffer is required. This provision shall only apply to features in or near wetlands, wildlife habitat areas, and geologically hazardous areas, except for seismic and volcanic hazards.

(2) This provision may be modified by the administrator upon the submittal of a specific construction proposal by the applicant that demonstrates that the critical area or buffer will not be disturbed.

(3) The following uses shall be allowed in the building setback:

(a) Landscaping;

(b) Uncovered decks;

(c) Building overhangs;

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

(e) Clearing and grading; and

(f) Wells. [Ord. 1284 §4, 2018]

(1) Properties located in critical areas or their buffers shall receive notice of their proximity to the critical area. This notice shall note the general presence of a critical area or buffer on the property, and the fact that limitations on actions in or affecting the critical area or buffer exist.

(2) The notice shall occur in the following manner:

(a) For building or development permits, this notice shall be provided as a condition of permit approval.

(b) Where the approval is a subdivision or binding site plan, the notice shall be recorded on the face of the plat. [Ord. 1284 §4, 2018]

This chapter shall be cited as the Lewis County right to farm chapter. [Ord. 1269 §28, 2016; Ord. 1197 §3, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1119 §1, 1991]

It is the purpose of this chapter to promote and protect agriculture and farm forestry in the Agricultural Resource Lands (ARL), Forest Resource Lands (FRL), and Rural Development District (RDD) zones through the enhancement, protection and perpetuation of the ability of farmers to conduct farming and forestry in accordance with RCW 7.48.305.

(1) Where nonresource land uses extend into natural resource areas or exist side-by-side, natural resource management operations are frequently the subjects of nuisance complaints and on occasion have been forced to cease or curtail operations. Such nuisance complaints discourage investments in natural resource land improvements to the detriment of adjacent natural resource land uses and the economic viability of the county’s resource industry as a whole. It is the purpose and intent of this chapter to reduce the loss of its natural resource lands by limiting and defining the circumstances under which natural resource lands management operations may be considered a nuisance. This chapter is not to be construed as in any way modifying or abridging county, state or federal laws; rather it is only to be utilized in the interpretation and enforcement of the provisions of this code and county regulations.

(2) An additional purpose of this chapter is to promote a good neighbor policy between natural resource lands and nonresource land property owners by advising purchasers, developers and users of property adjacent to or near natural resource land management operations of the inherent potential problems associated with such purchase of the property, including, but not limited to, the use of chemicals, or from spraying, pruning, harvesting, or mineral extraction with associated activities, which occasionally generates traffic, dust, smoke, noise, odor and the hours of operation that may accompany natural resource land management operations. It is intended that through mandatory disclosures purchasers and users will better understand the impact of living near natural resource lands and be prepared to accept attendant conditions as the natural result of living in or near natural resource lands and rural areas.

(3) An additional purpose of this chapter is to provide notice, through a disclosure statement, of the potential incompatibilities, inconveniences and discomforts that may arise from natural resource land management activities. [Ord. 1269 §28, 2016; Ord. 1197 §3, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1119 §2, 1991]

No agricultural activity, operation, facility or appurtenances thereof shall be or become a nuisance as defined in Chapter 1.22 LCC, regardless of past or future changes in the surrounding area’s land use or zoning designation, when conducted or maintained for commercial purposes, and in a manner consistent with current best management practices, not superseding local, state or federal regulations and involving uses allowed under the Agriculture Resource Land (ARL) and Rural Development District (RDD) zones.

(1) Notwithstanding any other provision in this chapter, agricultural activities conducted on ARL or RDD farmlands, if consistent with good and generally accepted agricultural and management practices and established prior to surrounding activities, are presumed to be reasonable and shall not be found to constitute a nuisance unless the activity has a substantial adverse effect on the public health and safety.

(2) If that agricultural activity is undertaken in conformity with generally accepted agricultural and management practices and with federal, state and local laws and regulations and health department guidelines, it is presumed to be good agriculture practice and not adversely affecting the public health and safety.

(3) A farm operation shall not be restricted in its activities to time of day or days of the week, but shall be conducted according to generally accepted agricultural and management practices. [Ord. 1269 §28, 2016; Ord. 1197 §3, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1119 §4, 1991]

Disclosure of proximity to agricultural activities shall occur in accordance with RCW 64.06.022 and the standards in LCC 17.30.370. [Ord. 1269 §28, 2016; Ord. 1197 §3, 2007]

(1) To minimize possible adverse environmental effects, those engaged in agricultural activities shall apply chemical products in accordance with all label instructions and shall abide by all applicable state and federal laws and regulations as well as with generally accepted agricultural and management practices.

(2) A farm or farm operation shall not be found to be a public or private nuisance if the farm or farm operation conforms to generally accepted agricultural and management practices, recognizing that those practices may be subject to varying conditions including, but not limited to, geographic location, weather, soil types and conditions, type of crop or livestock, and management systems. [Ord. 1269 §28, 2016; Ord. 1197 §3, 2007; Ord. 1170B, 2000; Ord. 1157, 1998; Ord. 1119 §5, 1991. Formerly 17.40.050]
