14.08.010 Purpose.
It is the purpose of this chapter:

To protect human life and health;
To minimize expenditure of public money and costly flood control and flood relief projects;
To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
To minimize prolonged business interruptions;
To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets, and bridges located in areas of special flood hazard;
To help maintain a stable tax base by providing for the sound use and development of areas of special flood hazard so as to minimize future flood blight areas;
To ensure that potential buyers are notified that property is in an area of special flood hazard;
To ensure that those who occupy the areas of special flood hazard assume responsibility for their actions; and
To administer the Washington State Floodplain Management Act (Chapter 86.16 RCW) and maintain Kittitas County's eligibility to participate in the National Flood Insurance Program. (Ord. 2001-03; Ord. 93-18 § 1, 1993).

14.08.015 Methods of reducing flood losses.
In order to accomplish its purposes, this chapter includes methods and provisions for:

Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities;
Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel flood waters;
Controlling filling, grading, dredging, and other development which may increase flood damage; and
Preventing or regulating the construction of flood barriers which will unnaturally divert floodwaters or may increase flood hazards in other areas. (Ord. 2001-03).

14.08.020 Definitions.
Unless specifically defined below, words or phrases used in this chapter shall be interpreted so as to give them the meaning they have in common usage and to give this chapter it's most reasonable application.

Accessory Structure

A structure on the same parcel of property as a principal structure and the use of which is incidental to the use of the principal structure. For floodplain management purposes, the term includes only accessory structures used for parking and storage.

Alteration of watercourse

Any action that will change the location of the channel occupied by water within the banks of any portion of a riverine waterbody.

Appeal

A request for review of the county floodplain administrator's interpretation or application of any provision of this chapter or a request for a variance.

Area of shallow flooding

A designated AO, AH, AR/AH Zone on the Flood Insurance Rate Map (FIRM) with a one percent or greater annual chance of flooding to an average depth range from one to three feet, a clearly defined channel does not exist, the path of flooding is unpredictable and indeterminate, and velocity flow may be evident. AO is characterized as sheet flow and AH indicates ponding.

Area of special flood hazard

The land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year. Designation on FIRM maps include the letters A, AO, AH, A1-30, AE, A99 and AR. Also referred to as "100-year floodplain" and "special flood hazard area."

Agriculture

"Agriculture" is the grazing, feeding, and watering of livestock; plowing, seeding, cultivation, and harvesting for the production of crops and pasture; soil and water conservation practices; the maintenance of farm or stock ponds, irrigation ditches, irrigation structures, drainage ditches, underground drainage systems, fences and farm roads, the control of noxious weeds or other generally accepted agriculture practices, and for purposes of this chapter does not include associated structures and/or appurtenances.

ASCE 24

The most recently published version of ASCE 24, Flood Resistant Design and Construction, published by the American Society of Civil Engineers.

Base flood

The flood having a one percent chance of being equaled or exceeded in any given year. Also referred to as the "100-year flood."

Base flood elevation

The computed elevation to which flood water is anticipated to rise during the base flood period. Base Flood Elevations (also referred to as BFEs) are shown on Flood Insurance Rate Maps (FIRMs) and on the flood profiles. The BFE is the regulatory requirement for the elevation or floodproofing of structures. Relationship between the BFE and a structure's elevation determines the flood insurance premium.

Basement

Any area of the building having its floor subgrade (below ground level) on all sides.

Best available information

In the absence of official flood insurance rate map data, communities can use data from other federal, state, or other sources provided this data has either been generated using technically defensible methods or is based on reasonable historical analysis and experience.

Building

See "Structure"

Building Code

The most current edition of the International Building Code and the International Residential Code as adopted and amended by the Washington State Building Code Council.

Critical facility

A facility for which even a slight chance of flooding might be too great. Critical facilities include, but are not limited to, schools, nursing homes, hospitals, police, fire and emergency response installations, installations which produce, use or store hazardous materials or hazardous waste, and certain service facilities for utilities and special utilities (as defined under Chapter 17.61 KCC) as determined by the administrator.

Development

Any manmade change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials located within the areas of special flood hazard.

Existing manufactured home park or subdivision

A manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed before the effective date of the adopted floodplain management regulations.

Expansion to an existing manufactured home park or subdivision

The preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads).

Flood (or "flooding")

A general and temporary condition of partial or complete inundation of normally dry land areas from the unusual and rapid accumulation of runoff or surface waters from:

The overflow of inland or tidal waters.
The unusual and rapid accumulation or runoff of surface waters from any source.

Mudslides (i.e., mudflows) which are proximately caused by flooding as defined in paragraph (1)(b) of this definition and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.
The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature, such as flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in paragraph (1)(a) of this definition.

Flood elevation study

An examination, evaluation and determination of flood hazards and, if appropriate, corresponding water surface elevations, or an examination, evaluation and determination of mudslide (i.e., mudflow) and/or flood-related erosion hazards. Also known as a Flood Insurance Study (FIS).

One-hundred-year flood or 100-year flood

See "Base flood"

Reasonably Safe from Flooding

Development that is designed and built to be safe from flooding based on consideration of current flood elevation studies, historical data, high water marks and other reliable date known to the community. In unnumbered A zones where flood elevation information is not available and cannot be obtained by practicable means, reasonably safe from flooding means that the lowest floor is at least two feet above the Highest Adjacent Grade.

Recreational vehicle

A vehicle which is:

Built on a single chassis;

For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.

Structure

A walled and roofed building, including gas or liquid storage tanks, that are principally above ground, as well as a manufactured home.

Substantial damage

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

Substantial improvement

Any reconstruction, rehabilitation, addition or improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the "start of construction" of the improvement. This term includes structures which have incurred “substantial damage,” regardless of the actual repair work performed. The term does not include either:

any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions, or
any alteration of a historic structure provided that the alteration will not preclude the structure's continued designation as a "historic structure.”

Variance

A grant of relief from the requirements of this chapter which permits construction in a manner that would otherwise be prohibited by this chapter.

Water surface elevation

The height, in relation to the vertical datum utilized in the applicable flood insurance study of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.

Water dependent

(Ord. 2021-010, 2021; Ord. 2014-015, 2014; Ord. 2001-03; Ord. 93-18 § 4.7, 1993)

Article IV. Variance Procedure

The variance criteria set forth in this section of the ordinance are based on the general principle of zoning law that variances pertain to a piece of property and are not personal in nature. A variance may be granted for a parcel of property with physical characteristics so unusual that complying with the requirements of this ordinance would create an exceptional hardship to the applicant or the surrounding property owners. The characteristics must be unique to the property and not be shared by adjacent parcels. The unique characteristic must pertain to the land itself, not to the structure, its inhabitants, or the property owner.

It is the duty of the Kittitas County Hearings Examiner to help protect its citizens from flooding. T his need is so compelling and the implications of the cost of insuring a structure built below the Base Flood Elevation are so serious that variances from the flood elevation or from other requirements in the flood ordinance are quite rare. T he long-term goal of preventing and reducing flood loss and damage can only be met if variances are strictly limited. Therefore, the variance guidelines provided in this ordinance are more detailed and contain multiple provisions that must be met before a variance can be properly granted. The criteria are designed to screen out those situations in which alternatives other than a variance are more appropriate.

14.08.160 Appeal board.

The Kittitas County Hearings Examiner as established by the county shall hear and decide appeals and requests for variances from the requirements of this chapter.
The Hearings Examiner shall hear and decide appeals when it is alleged there is an error in any requirement, decision, or determination made by the county in the enforcement or administration of this chapter.
Those aggrieved by the decision of the Hearings Examiner or any taxpayer may appeal such decision to the Kittitas County superior court as provided by law.
In passing upon such applications, the Hearings Examiner shall consider all technical evaluations, all relevant factors, standards specified in other sections of this chapter, and the following:
1. The danger that materials may be swept onto other lands to the injury of others;
2. The danger to life and property due to flooding or erosion damage;
3. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
4. The importance of the services provided by the proposed facility to the community;
5. The necessity to the facility of a waterfront location, where applicable;
6. The availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
7. The compatibility of the proposed use with existing and anticipated development;
8. The relationship of the proposed use to the comprehensive plan and floodplain management program for the area;
9. The safety of access to the property in times of flood for ordinary and emergency vehicles;
10. The expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and
11. The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems, and streets and bridges.
Generally, the only condition under which a variance from the elevation standard may be issued is for new construction and substantial improvements to be erected on a lot one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood elevation provided subsections (4)(a) through (k) of this section have been fully considered. As the lot size increases, the technical justification required for issuing the variance increases.
Upon consideration of the factors of subsection (4) of this section and the purposes of this chapter, the Hearings Examiner may attach such conditions to the granting of a variance as it deems necessary to further the purposes of this chapter.
The Floodplain Administrator shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request.
After the county has rendered an order either granting or denying a flood control zone permit, said order may be appealed to the Pollution Control Hearings Board pursuant to state law.

(Ord. 2021-010, 2021; Ord. 2014-015, 2014; Ord. 2007-22, 2007; Ord. 2001-03; Ord. 93-18 § 4.8, 1993)

14.08.170 Conditions for variances.

Variances may be issued for the reconstruction, rehabilitation, or restoration of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. Variance requests in the designated floodway shall be accompanied by a professional engineering analysis of the resultant base flood discharge.
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief and upon:
1. A determination that failure to grant the variance would result in exceptional hardship to the applicant; and
2. A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create a nuisance, cause fraud or victimization of the public, or conflict with existing local laws or ordinances.
3. A showing of good and sufficient cause.
4. A showing that the use cannot perform its intended purpose unless it is located or carried out in close proximity to water. This includes only facilities defined in Section 14.08.020 of this ordinance in the definition of “Functionally Dependent Use.”
Variances as interpreted in the National Flood Insurance Program are based on the general zoning law principle that they pertain to a physical piece of property; they are not personal in nature and do not pertain to the structure, its inhabitants, economic or financial circumstances. They primarily address small lots in densely populated residential neighborhoods. As such, variances from the flood elevation requirements should be quite rare.
Variances may be issued for nonresidential buildings in very limited circumstances to allow a lesser degree of flood-proofing than watertight or dry-flood-proofing, where it can be determined that such action will have low damage potential, and comply with all other variance criteria.
The Floodplain Administrator shall condition the variance as needed to ensure that the requirements and criteria of this ordinance are met.
Any applicant to whom a variance is granted shall be given written notice over the signature of a community official that the issuance of a variance to construct a structure below the base flood elevation will result in increased premium rates for flood insurance and that such construction below the base flood elevation increases risks to life and property and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation.

14.08.300 Floodways.
Located within areas of special flood hazard established in KCC 14.08.040 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters which carry debris and potential projectiles, and erosion potential, the following provisions apply:

Prohibit encroachments, including fill, new construction, substantial improvements, and other development, unless certification by a registered professional engineer is provided demonstrating through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels during the occurrence of the base flood discharge.
Construction or reconstruction of residential structures is prohibited within designated floodways, except for:
1. Repairs, reconstruction, or improvements to a structure which do not increase the ground floor area; and
2. Repairs, reconstruction or improvements to a structure, the cost of which does not exceed 50 percent of the market value of the structure either: (i) before the repair or reconstruction is started, or (ii) if the structure has been damaged, and is being restored, before the damage occurred. Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety codes which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions or to structures identified as historic places shall not be included in the 50 percent.
If subsection (1) of this section is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of KCC 14.08.180 through 14.08.310, provisions for flood hazard reduction, except for construction and reconstruction of residential structures that is prohibited by subsection (2) of this section.

14.08.310 Standards for shallow flooding areas (AO Zones).

Shallow flooding areas appear on FIRMs as AO Zones with depth designations. The base flood depths in these zones range from one to three feet above ground where a clearly defined channel does not exist, or where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is usually characterized as sheet flow. In these areas, the following provisions apply:

New construction, substantial improvements, and reconstruction due to substantial damage of residential structures and manufactured homes within AO Zones:
1. Shall have the lowest floor (including basements) elevated above the highest grade adjacent to the building, one foot or more above the depth number specified in feet on the FIRM (at least two feet above the highest adjacent grade to the structure if no depth number is specified).
2. Any interior or exterior building utility systems must be elevated one-foot or more above the depth number specified in feet on the FIRM (at least two feet above the highest adjacent grade to the structure if no depth number is specified)with the exception of utility meters and equipment specifically designed to withstand inundation according to the standards of the International Residential Codes and the NFIP.
New construction and substantial improvements of nonresidential structures within AO Zones shall either:
1. Have the lowest floor (including basement) elevated above the highest adjacent grade of the building site, one foot or more above the depth number specified on the FIRM (at least two feet if no depth number is specified); or
2. Together with attendant utility and sanitary facilities, be completely flood-proofed to or above that level so that any space below that level is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. If this method is used, compliance shall be certified by a registered professional engineer or architect as in KCC 14.08.270(3).
Require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.
Recreational vehicles placed on sites within AO zones on the community’s FIRM either:
1. Be on the site for fewer than 180 consecutive days, or
2. Be fully licensed and ready for highway use, on its wheels or jacking system, is attached to the site only by quick disconnect type utilities and security devices, and has no permanently attached additions; or
3. Meet the requirements of subsections (1) and (3) above and the anchoring requirements for manufactured homes (Section 14.08.190(2).

14.12.010 System adopted.
The Kittitas County Board of Commissioners hereby adopts the wildfire hazard severity classification system developed to determine the Fire Hazard Area Classification in unincorporated areas of Kittitas County that are located outside of a fire department. This rating system was developed by the Rural Fire Protection District in cooperation with the Wildland Protection Agencies incorporating the natural factors of wildland fuels (timber, brush), slope (steepness of ground), aspect (direction of sun exposure), and climate into a "Wildfire Hazard Severity Classification System." These factors are reflected in four separate risk groups - low, moderate, high and extreme and they are incorporated into the wildfire hazard severity rating system requirements found in KCC 14.12.020, 14.12.030, 14.12.040, and 14.12.050. (Ord. 2007-29, 2007; Ord. 90-16 § 1, 1990).

14.12.020 Minimum standards.
Roof coverings placed on all new buildings and on all buildings being re-roofed as defined in KCC 14.12.090(3) in the unincorporated areas of Kittitas County shall have at least a "Class C" or better fire resistant/retardant rating as established by the International Building Code Chapter 1505.4, unless such roof coverings are governed by other more restrictive standards set out in this chapter, other ordinances of Kittitas County, or applicable state or federal standards. (Ord. 2007-29, 2007; Ord. 90-16 § 2, 1990).

14.12.030 High and extreme fire hazard areas.
In high and extreme fire hazard areas as determined by wildfire hazard severity classification, roof coverings placed on all new buildings and on all buildings being re-roofed as defined in KCC 14.12.090(3) shall be of fire resistant/retardant materials with no less than a "Class A" rating as defined by the International Building Code Chapter 1505.2, or as otherwise approved in writing with supporting reasons by the Kittitas County Fire Marshal. (Ord. 2007-29, 2007; Ord. 90-16 § 3, 1990).

14.12.040 Moderate fire hazard areas.
In moderate fire hazard areas as determined by wildfire hazard severity rating, roof coverings placed on all new buildings and on all buildings being re-roofed as defined in KCC 14.12.090(3) shall be of fire resistant/retardant materials with no less than a "Class B" rating as defined by the International Building Code Chapter 1505.3, or as otherwise approved in writing with supporting reasons by the Kittitas County Fire Marshal. (Ord. 2007-29, 2007; Ord. 90-16 § 4, 1990).

14.12.050 Low fire hazard areas.
In low fire hazard areas as determined by wildfire hazard severity rating, roof coverings placed on all new buildings and on all buildings being re-roofed as defined in KCC 14.12.090(3) shall be of fire resistant/retardant materials with no less than a "Class C" rating as defined by the International Building Code Chapter 1505.2, or as otherwise approved in writing with supporting reasons by the Kittitas County Fire Marshal. (Ord. 2007-29, 2007; Ord. 90-16 § 5, 1990).
