Streams also include natural watercourses modified by man. Streams do not 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.

(114)

Sub-Drainage Basin or Subbasin means the drainage area of the highest order stream containing the subject property impact area. Stream order is the term used to define the position of a stream in the hierarchy of tributaries in the watershed. The smallest streams are the highest order (first order) tributaries. These are the upper watershed streams and have no tributaries of their own. When two first order streams meet, they form a second order stream, and when two second order streams meet they become a third order stream, and so on.

(115)

Substantial Damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred.

(116)

Substantial Improvement means any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure either: before the improvement or repair is started; or if the structure has been damaged and is being restored, before the damage occurred.

(117)

Take means to harass, harm, pursue, hunt, shoot, wound, kill, capture, or collect, or to attempt to engage in any such conduct.

(118)

Unavoidable means adverse impacts that remain after all appropriate and practicable avoidance and minimization have been achieved. See RCW 90.84.010(9).

(119)

Vulnerability means the combined effect of susceptibility to contamination and the presence of potential contaminants.

(120)

Water Dependent means a use or portion of a use that cannot exist in a location that is not adjacent to the water, but is dependent on the water by reason of the intrinsic nature of its operations. A use that can be carried out only on, in, or adjacent to water. Examples of water dependent uses include ship cargo terminal loading areas; fishing; ferry and passenger terminals; barge loading, ship building, and dry docking facilities; marinas, moorage, and boat launching facilities; aquaculture; float plane operations; surface water intake; and sanitary sewer and storm drain outfalls.

(121)

Water Resource Inventory Area (WRIA) means one of 62 watersheds in the state of Washington, each composed of the drainage areas of a stream or streams, as established in Chapter 173-500 WAC as it existed on January 1, 1997.

(122)

Water Table means that surface in an unconfined aquifer at which the pressure is atmospheric. It is defined by the levels at which water stands in wells that penetrate the aquifer just far enough to hold standing water.

(123)

Water Table Aquifer. See "Aquifer, unconfined."

(124)

Water Typing System are waters classified according to WAC 222-16-031 including the following:

(a)

Type 1 Water - All waters, within their ordinary high-water mark, as inventoried as "shorelines of the state" under Chapter 90.58 RCW and the rules promulgated pursuant to Chapter 90.58 RCW, but not including those waters associated with wetlands as defined in Chapter 90.58 RCW.

(b)

Type 2 Water - Segments of natural waters that are not classified as Type 1 Water and have a high fish, wildlife, or human use. These are segments of natural waters and periodically inundated areas of their associated wetlands, which:

(i)

Are used by fish for spawning, rearing or migration. Waters having the following characteristics are presumed to have highly significant fish populations:

(A)

Stream segments having a defined channel 20 feet or greater within the bankfull width and having a gradient of less than four percent.

(B)

Lakes, ponds, or impoundments having a surface area of one acre or greater at seasonal low water; or

(ii)

Are used by fish for off-channel habitat. These areas are critical to the maintenance of optimum survival of fish. This habitat shall be identified based on the following criteria:

(A)

The site must be connected to a fish bearing stream and be accessible during some period of the year; and

(B)

The off-channel water must be accessible to fish through a drainage with less than a five percent gradient.

(c)

Type 3 Water - Segments of natural waters that are not classified as Type 1 or 2 Waters and have a moderate to slight fish, wildlife, and human use. These are segments of natural waters and periodically inundated areas of their associated wetlands which:

(i)

Are used by fish for spawning, rearing or migration. The requirements for determining fish use are described in the State Forest Practices Board Manual, Section 13. If fish use has not been determined:

(A)

Waters having the following characteristics are presumed to have fish use:

(I)

Stream segments having a defined channel of three feet or greater in width and having a gradient of 16 percent or less.

(II)

Stream segments having a defined channel or three feet or greater within the bankfull width, and having a gradient greater than 16 percent and less than or equal to 20 percent, and having greater than 175 acres contributing basin size, based on hydrographic boundaries;

(III)

Ponds or impoundments having a surface area of less than one acre at seasonal low water and having an outlet to a fish stream;

(IV)

Ponds of impoundments having a surface area greater than one-half acre at seasonal low water.

(B)

The Department of Natural Resources shall waive or modify the characteristics in (a) of this Subsection where:

(I)

Waters have confirmed, long term, naturally occurring water quality parameters incapable of supporting fish;

(II)

Snowmelt streams have short flow cycles that do not support successful life history phases of fish. These streams typically have no flow in the winter months and discontinue flow by June 1; or

(III)

Sufficient information about a geomorphic region is available to support a departure from the characteristics in (a) of this Subsection, as determined in consultation with the Department of Fish and Wildlife, Department of Ecology, affected tribes and interested parties.

(d)

Type 4 Water - All segments of natural waters within the bankfull width of defined channels that are perennial nonfish habitat streams. Perennial streams are waters that do not go dry any time of a year of normal rainfall. However, for the purpose of water typing, Type 4 Waters include the intermittent dry portions of the perennial channel below the uppermost point of perennial flow. If the uppermost point of perennial flow cannot be identified with simple, nontechnical observations (see State Forest Practices Board Manual, Section 23), then Type 4 Waters begin at a point along the channel where the contributing basin area is at least 300 acres.

(e)

Type 5 Waters - All segments of natural waters within the bankfull width of the defined channels that are not Type 1, 2, 3, or 4 Waters. These are seasonal, nonfish habitat streams in which surface flow is not present for at least some portion of the year and are not located downstream from any stream reach that is a Type 4 Water. Type 5 Waters must be physically connected by an above-ground channel system to Type 1, 2, 3, or 4 Waters.

(125)

Well is a bored, drilled or driven shaft, or a dug hole whose depth is greater than the largest surface dimension for the purpose of withdrawing or injecting water or other liquids.

(126)

Wellhead Protection Area (WHPA) is the portion of a zone of contribution for a well, wellfield or spring, as defined using criteria established by the state Department of Ecology.

(127)

Wetlands are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas. Wetlands do not include those artificial wetlands intentionally created from non-wetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. Wetlands may include those artificial wetlands intentionally created from non-wetland areas to mitigate the conversion of wetlands. Identification and delineation of Wetlands is also a product of the Washington State Wetland Identification and Delineation Manual (KMC 18.59.010).

(128)

Wetland Category are wetlands that are categorized into Category I, II, III or IV based upon the categorization procedures in the Washington State Wetland Rating System for Eastern Washington (Hruby T. 2004).

(129)

Wetland Classes, Classes of Wetlands, or Wetland Types are the descriptive classes of the wetlands taxonomic classification system of the U.S. Fish and Wildlife Service (Cowardin, et al. 1979).

(130)

Wetland Edge means the boundary of a wetland as delineated based on the definitions contained in this Title.

(131)

Wetlands Mitigation Bank means a site where wetlands are restored, created, enhanced, or in exceptional circumstances, preserved expressly for the purpose of providing compensatory mitigation in advance of authorized impacts to similar resources. See RCW 90.84.010(5).

(132)

Zone of Contribution means the area surrounding a well or spring that encompasses all areas or features that supply ground water recharge to the well or spring.

(Ord. 5206 Sec. 1, 2007)

(1)

The purpose of this Title is to designate and classify ecologically sensitive and hazardous areas and to protect these areas and their functions and values, while also allowing for reasonable use of private property.

(2)

This Title is to implement the goals, policies, guidelines, and requirements of the City of Kennewick (City) Comprehensive Plan and the Growth Management Act.

(3)

The City finds that critical areas provide a variety of valuable and beneficial biological and physical functions that benefit the City and its residents, and/or may pose a threat to human safety or to public and private property. The beneficial functions and values provided by critical areas include, but are not limited to, water quality protection and enhancement, fish and wildlife habitat, support of trophic relationships, flood storage, conveyance and attenuation, ground water recharge and discharge, erosion control, wave attenuation, protection from hazards, historical and archaeological and aesthetic value protection, and recreation. These beneficial functions are not listed in order of priority.

(4)

Goals. By identifying development impacts to critical areas, this Title seeks to:

(a)

Protect members of the public and public resources and facilities from injury, loss of life, or property damage due to landslides and steep slope failures, erosion, seismic events, volcanic eruptions, or flooding;

(b)

Protect unique, fragile, and valuable elements of the environment, including ground and surface waters, wetlands, and fish and wildlife and their habitats;

(c)

Direct activities not dependent on critical area resources to less ecologically sensitive sites and

(d)

Mitigate unavoidable impacts to critical areas by regulating alterations in and adjacent to critical areas; and

(e)

Prevent cumulative adverse environmental impacts to water quality, wetlands, and fish and wildlife habitat, and the overall net loss of wetlands, frequently flooded areas and habitat conservation areas.

(5)

This Title is intended to protect critical areas in accordance with the Growth Management Act and through the application of best available science, as determined according to WAC 365-195-900 through 365-195-925, and in consultation with state and federal agencies and other qualified professionals.

(6)

This Title is to be administered with flexibility and attention to site-specific characteristics. It is not the intent of this Title to make a parcel of property unusable by denying its owner reasonable economic use of the property.

(7)

The City's enactment or enforcement of this Title shall not be construed for the benefit of any individual person or group of persons other than the general public.

(Ord. 5206 Sec. 1, 2007)

(1)

As provided herein, the Planning Director is given the authority to interpret and apply and the responsibility to enforce this Title to accomplish the stated purpose.

(2)

The City shall not approve any permit or otherwise issue any authorization to alter the condition of any land, water, or vegetation, or to construct or alter any structure or improvement in, over, or on a critical area or associated buffer, without first assuring compliance with the requirements of this Title.

(3)

The provisions of this Title shall apply to all lands, all land uses and development activity, and all structures and facilities in the City, whether or not a permit or authorization is required, and shall apply to every person, firm, partnership, corporation, group, governmental agency, or other entity that owns, leases, or administers land within the City. No person, company, agency, or applicant shall alter a critical area or buffer except as consistent with the purposes and requirements of this Title.

(4)

Approval or denial of a permit or development proposal pursuant to the provisions of this Title does not discharge the obligation of the applicant to comply with the provisions of this Title.

(Ord. 5206 Sec. 1, 2007)

(1)

(Ord. 5206 Sec. 1, 2007)

(1)

The City shall regulate all uses within 200 feet (based on the maximum buffer size recommended in this Title. See Chapter 18.59 for additional information) of, or that are likely to affect, one or more critical areas, consistent with the best available science and the provisions herein.

(2)

Critical areas regulated by this Title include:

(a)

Wetlands as designated in Chapter 18.59;

(b)

Critical aquifer recharge areas as designated in Chapter 18.60;

(c)

Frequently flooded areas as designated in Chapter 18.61;

(d)

Geologically hazardous areas as designated in Chapter 18.62; and

(e)

Fish and wildlife habitat conservation areas as designated in Chapter 18.63.

(3)

All areas within the City meeting the definition of one or more critical area, regardless of any formal identification, are hereby designated critical areas and are subject to the provisions of this Title.

(Ord. 5206 Sec. 1, 2007)

Any mitigation action taken pursuant to this Title shall result in equivalent or greater functions and values of the critical areas associated with the proposed action, as determined by the best available science. All actions and developments shall be designed and constructed in accordance with Mitigation Sequencing requirements in Section 18.58.170 to avoid, minimize and restore all adverse impacts. Applicants must first demonstrate an inability to avoid or reduce impacts, before restoration and compensation of impacts will be allowed. No activity or use shall be allowed that results in a net loss of the functions or values of critical areas.

(Ord. 5206 Sec. 1, 2007)

(1)

Best Available Science to be Used Must be Consistent with Criteria. The best available science is that scientific information applicable to the critical area prepared by local, state or federal natural resource agencies, a qualified scientific professional or team of qualified scientific professionals that is consistent with criteria established in WAC 365-195-900 through WAC 365-195-925. In the context of critical areas protection, best available science must also be based upon a valid scientific process as defined in WAC 365-105-905. Best Available Science sources are available in Appendix A, which is adopted by reference and on file in the Department of Community Planning (Best Available Science References).

(2)

Absence of Valid Scientific Information. Where there is an absence of valid scientific information or incomplete scientific information relating to a critical area, leading to uncertainty about the specific boundary of a critical area, and risk to critical area function of permitting an alteration of or impact to the critical area, the Planning Director shall:

(a)

Maintain a critical areas designation certification program for wetlands, and fish and wildlife habitat conservation areas by periodically updating these maps with new information as it is provided to the City. Currently, the City has two types of boundaries depicted on the wetlands, and the fish and wildlife habitat conservation areas maps:

(i)

Certified - Where the critical area boundary has been verified and mapped within the past five years by a qualified professional (e.g. delineated wetland), hydrology of the site (applicable to wetlands only) has not been altered within that time period, and this territorial limit information has been provided to the City. Certified wetlands and fish and wildlife habitat as of 2007 include: Elliott Lake wetlands, 27th Avenue wetlands, Zintel Canyon, 36th Avenue wetland; wetlands and fish and wildlife habitat in Columbia Park, and the large contiguous block of shrub steppe habitat located adjacent to HWY 395 and Interstate I-82 on the southern portion of the City and its urban growth boundary.

(ii)

Uncertified - Where more specific information needs to be prepared by a qualified professional and provided to the City to accurately show the boundary of a given critical area, or where boundaries and conditions of certified wetlands and fish and wildlife habitat is more than five years old and needs to be verified.

(b)

The most recent map revision identifying certified and uncertified wetlands and fish and wildlife conservation areas becomes the map of record for demonstrating compliance with the state requirement for designating and classifying these critical areas.

(Ord. 5206 Sec. 1, 2007)

(1)

Process. The Planning Director shall allow activities that are verified to comply with this section. The Planning Director shall provide a copy of this section, including any future updates, and the maps of critical area designations to city departments and other potential affected agencies as determined by the Planning Director. City Departments and other local agencies when conducting allowed activities (except for 18.58.110(3)(c) and (d)), will notify the Planning Director in writing in advance of the planned activity, when it will occur, and steps that will be taken to comply with the provisions of this Title. Emergency activities or any other activities that occur without advance notice will be followed up with a report to the Planning Director describing how provisions of this Title are being met. Documentation of allowed activities shall be maintained on file at the Planning Department.

(2)

Allowed Activities shall Avoid Impacts to Critical Areas. All allowed activities shall use mitigation sequencing to avoid potential impacts to critical areas, using best management practices that result in the least amount of impact to the critical areas where practicable. Designation as an allowed activity does not give permission to degrade a critical area or ignore risk from natural hazards. Best management practices shall be used for tree and vegetation protection, construction management, erosion and sedimentation control, water quality protection, fish and wildlife protection, and regulation of chemical applications. The City shall monitor the use of best management practices to ensure that the activity does not result in degradation to the critical area. Any incidental damage to, or alteration of, a critical area that is not a necessary outcome of the exempted activity shall be restored, rehabilitated, or replaced at the responsible party's expense within one growing season.

(3)

Allowed Activities. The following developments, activities, and associated uses are allowed and shall be exempt from the provisions of this Title except as noted in provisions below, provided that they are otherwise consistent with the provisions of other local, state, and federal laws and requirements:

(a)

Emergencies. Emergency activities are 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 timeframe too short to allow for compliance with the requirements of this Title.

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 City within one working day following commencement of the emergency activity. Within 30 days, the Planning Director shall determine if the action taken was within the scope of the emergency actions allowed in this Subsection. If the Planning Director determines that the action taken, or any part of the action taken, was beyond the scope of an allowed emergency action, then enforcement provisions of Section 18.58.190 shall apply.

After the emergency, the person or agency undertaking the action shall fully restore and/or mitigate any impacts to the critical area and buffers resulting from the emergency action in accordance with the critical area report or other applicable information, and mitigation plan. The person or agency undertaking the action shall apply for review, and the alteration, critical area report or other applicable information, and mitigation plan shall be reviewed by the City in accordance with the review procedures contained herein. Restoration and/or mitigation activities must be initiated within one year of the date of the emergency, and completed in a timely manner;

(b)

Operation, Maintenance or Repair. Operation, maintenance or repair of existing structures, infrastructure improvements, utilities, public or private roads, dikes, levees or drainage systems, that do not require a permit or are covered under a programmatic permit from an authorized agency, if the activity does not further alter or increase the impact to, or encroach further within, the critical area or buffer and there is no increased risk to life or property as a result of the proposed operation, maintenance, or repair;

(c)

Passive Outdoor Activities. Recreation, education, and scientific research activities that do not degrade the critical area, including fishing, hiking, and bird watching.

(d)

Permit Requests Subsequent to Previous Critical Area Review. Development permits and approvals that involve both discretionary land use approvals (such as subdivisions, rezones, or conditional use permits), and construction approvals (such as building permits) if all of the following conditions have been met:

(i)

The provisions of this Title have been previously addressed as part of another approval;

(ii)

There have been no material changes in the potential impact to the critical area or buffer since the prior review;

(iii)

There is no new information available that is applicable to any critical area review of the site or particular critical area;

(iv)

The permit or approval has not expired or, if no expiration date, no more than five years has elapsed since the issuance of that permit or approval; and

(v)

Compliance with any standards or conditions placed upon the prior permit or approval has been achieved or secured.

(e)

Modification to Existing Structures. Structural modification of, addition to, or replacement of an existing legally constructed structure that does not further alter or increase the impact to the critical area or buffer and there is no increased risk to life or property as a result of the proposed modification or replacement, provided that restoration of structures substantially damaged by fire, flood, or act of nature must be initiated within six months of the date of such damage, as evidenced by the issuance of a valid building permit, and diligently pursued to completion;

(f)

Activities within the Improved Right-Of-Way. Replacement, modification, installation, or construction of utility facilities, lines, pipes, mains, equipment, or appurtenances, not including substations, when such facilities are located within the improved portion of the public right-of-way or a City authorized private roadway except those activities that alter a wetland or watercourse, such as culverts or bridges, or results in the transport of sediment or increased stormwater;

(g)

Public and Private Pedestrian Trails. Public and private pedestrian trails not in wetlands, or fish and wildlife habitat conservation areas, where the trail surface meets all other requirements;

(h)

Select Vegetation Removal Activities. Select vegetation removal activities are allowed upon review and approval of the Director. Accepted vegetation removal activities include: a) removing and controlling invasive plants or noxious weeds; b) removal of trees that are hazardous, posing a threat to public safety, or posing an imminent risk of damage to private property and measures to control a fire or halt the spread of disease or damaging insects consistent with the State Forest Practices Act, Chapter 76.09 RCW. Unless otherwise provided or as a necessary part of an approved alteration, removal of any vegetation or woody debris from a habitat conservation area or wetland shall be prohibited;

(i)

Chemical Applications. The application of herbicides, pesticides, organic or mineral-derived fertilizers, or other hazardous substances, if necessary, provided that their use shall be conducted in accordance with applicable state and federal law. (More information on commercial and residential use of chemicals can be found in Department of Ecology "Guidance Document for Establishment of Critical Aquifer Recharge Areas Ordinances" Version 3.0, Publication #97-30; and from the state Department of Agriculture, http://www.wa.gov/agr/);

(j)

Minor Site Investigative Work. Work necessary for land use submittals, such as topographic surveys, soil logs, percolation tests, and other related activities, where such activities do not require construction of new roads or significant amounts of excavation. In every case, impacts to the critical area shall be minimized and disturbed areas shall be immediately restored; and

(k)

Navigational Aids and Boundary Markers. Construction or modification of navigational aids and boundary markers.

(Ord. 5206 Sec. 1, 2007)

(1)

If the application of this Title would deny all reasonable use of the subject property, the property owner may apply for an exception pursuant to this Section.

(2)

Exception Request and Review Process. An application for a reasonable use exception shall be made to the City and shall include a critical area report, including mitigation plan, if necessary; and any other related project documents, such as permit applications to other agencies, special studies, and environmental documents prepared pursuant to the State Environmental Policy Act (Chapter 43.21C RCW) (SEPA documents). The Planning Director shall determine whether an exception request shall be granted based on review of the submitted information, a site inspection, and the proposal's ability to comply with reasonable use exception criteria. The Planning Director shall approve with conditions, or deny the request based on the proposal's ability to comply with the following reasonable use exception review criteria:

(a)

The application of this Title would deny all reasonable use of the property;

(b)

No other reasonable use of the property has less impact on the critical area;

(c)

Any alteration is the minimum necessary to allow for reasonable use of the property;

(d)

The inability of the applicant to derive reasonable use of the property is not the result of actions by the applicant after the effective date of this Title; and

(e)

The proposal meets the review criteria set forth in this Title.

(3)

Burden of Proof. The burden of proof shall be on the applicant to bring forth evidence in support of the application and to provide sufficient information on which any decision has to be made on the application.

(Ord. 5206 Sec. 1, 2007)

(1)

The City shall begin the process discussed below and outlined in Figure 1, within 90 days after permit application:

(a)

Verify the information submitted by the applicant for the applicable permit;

(b)

Evaluate the project area and vicinity for critical areas;

(c)

For wetland and/or fish and wildlife habitat conservation areas, the City may require that boundaries be verified and mapped by a qualified professional. The scale of the boundary information shall be the same as the City maps, and such boundaries shall be submitted to the City as part of the application for the applicable permit if the project is:

(i)

Within 200 feet of a wetland, or fish and wildlife critical area for which the boundaries have not been certified and depicted by the City on the critical areas map (see Exhibits 1 through 4 which are adopted by reference and on file in the Department of Community Planning); and

(ii)

Will not be receiving a no-impact waiver as provided in Section 18.58.130(2) below.

(d)

Determine whether the proposed project is likely to impact the functions or values of critical areas; and

(e)

Determine if the proposed project adequately addresses the impacts and avoids impacts to the critical area associated with the project.

(2)

Critical Areas Present, but No-Impact Waiver. If the Planning Director determines that there are critical areas within or adjacent to the project area, but that the proposed activity is unlikely to degrade the functions or values of the critical area, the Planning Director may waive the requirement for a report or other applicable information. If the waiver involves a wetland, the Planning Director may require a wetland category rating be completed prior to determining whether a waiver can be granted. A waiver may be granted if there is substantial evidence that all of the following requirements will be met:

(a)

There will be no alteration of the critical area or buffer;

(b)

The development proposal will not impact the critical area in a manner contrary to the purpose, intent, and requirements of this Title; and

(c)

The proposal is consistent with other applicable regulations and standards.

A summary of this analysis and the findings shall be included in any staff report or decision on the underlying permit.

Figure 1: City of Kennewick Critical Areas Permit Procedures and Coordination with Existing Permit Processes

(3)

Critical Areas Present and Potential Impact Likely. If the Planning Director determines that the proposed project is within, adjacent to, or is likely to impact a critical area, the Planning Director shall:

(a)

Notify the applicant that a critical area report, SEPA checklist, and other applicable information must be submitted prior to further review of the project, and indicate each of the critical area types that should be addressed;

(b)

Require a critical area report or other applicable information from the applicant that has been prepared by a qualified professional;

(c)
