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.

(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.

(Ord. 2021-010, 2021)

14.08.160 Appeal board.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. The Floodplain Administrator shall maintain the records of all appeal actions and report any variances to the Federal Insurance Administration upon request.
  8. 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.

  1. 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.
  2. 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.
  3. 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.”
  4. 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.
  5. 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.
  6. The Floodplain Administrator shall condition the variance as needed to ensure that the requirements and criteria of this ordinance are met.
  7. 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.

  2. Flood-proofing and sealing measures must be taken to ensure that toxic substances will not be displaced by or released into floodwaters; and
  3. Access routes to critical facilities shall be elevated to or above the base flood elevation to the extent possible. (Ord. 2012-009, 2012; Ord. 2001-03; Ord. 93-18 § 5.2.4, 1993).

14.08.285 Livestock Sanctuary Areas.
Elevated areas for the purpose of creating a flood sanctuary for livestock are allowed on farm units where livestock is allowed. Livestock flood sanctuaries shall be sized appropriately for the expected number of livestock and be elevated sufficiently to protect livestock. Proposals for livestock flood sanctuaries shall meet all procedural and substantive requirements of this chapter.

(Ord. 2021-010, 2021)

14.08.290 Manufactured homes.

  1. All manufactured homes to be placed or substantially improved on sites shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated one foot or more above the base flood elevation and be securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement.
  2. Any interior or exterior building utility systems must be elevated one-foot or more above the Base Flood Elevation (BFE) 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.

(Ord. 2021-010, 2021; Ord. 2012-009, 2012; 2007-34, 2007; Ord. 2001-03; Ord. 93-18 § 5.2.5, 1993).

14.08.295 Recreational vehicles.

  1. Recreational vehicles shall not be placed in a special flood hazard area from January 1st until the Wednesday before Memorial Day and again from November 15th through December 31st. The prohibition shall be inclusive of the end date of each period. An RV placed before the prohibited period shall not remain after November 14th; and
    • Exception: This regulation shall not be interpreted to prevent recreational use of property, but shall prohibit the unattended storage of all recreational vehicles and equipment during the flood season as outlined in 14.08.295 (1). If a notice of correction is placed upon the Recreational Vehicle and such notice is observed upon such Recreational Vehicle over 72 hours later, such observation shall create a rebuttable presumption of unattended storage. Such notice must reference that failure to remove it will create the before stated presumption.
    • Exception: Lawfully established, conditionally permitted uses (CUPs) such as campgrounds and recreational parks in existence prior to the adoption of this ordinance shall be allowed to continue their approved operations provided such uses are not dangerous to life and property and have and continue to comply with the laws and regulation as they existed at the time the CUP was issued. Such uses shall not be expanded and must comply with all rules and regulations regarding nonconforming uses.
  2. Recreational vehicles a shall:
    1. Be fully licensed and ready for highway use, on its wheels or jacking system, be attached to the site only by quick disconnect type utilities and security devices, and have no permanently attached additions.
    2. Be on the site for fewer than 180 days, or
    3. Meet the requirements of Section 14.08.290 above.
  3. Park Model Trailers as defined in KCC 14.04.045 shall not be placed in a flood hazard area.

Exception: to 1, 2, and 3 above. A recreational vehicle or Park Model Trailer being used as a primary residence and located in manufactured/mobile home community as defined in RCW 59.20.030 that was in existence before June 8, 2008 is exempted from the restrictions found in subsections 1, 2, and 3 above. The placement of such recreational vehicle or Park Model Trailer requires both a permit under KCC 17.92.020 and engineering to address the flood hazard. Additionally, such placement shall be conditioned upon meeting all the requirements placed upon a mobile and/or manufacture home in the same location.

(Ord. 2021-010, 2021; Ord. 2014-015, 2014; Ord. 2009-25, 2009; Ord. 200103)

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:

  1.  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.
  2.  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.
  3. 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.
  4. Traditional agricultural practices are exempt.

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:

  1. 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.
  2. 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).
  3. Require adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures.
  4. 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).

(Ord. 2021-010, 2021; Ord. 2014-015, 2014; Ord. 2009-25, 2009; Ord. 2001-03; Ord. 93-18 § 5.5, 1993. Formerly 14.08.320)

14.08.315 Standards for filling, grading in floodplain.
Filling, grading or other activity that would reduce the effective storage volume shall be mitigated by creating compensatory storage on-site, or off-site if legal arrangements can be made, to assure that the effective compensatory storage volume will be preserved over time; provided, however, that no increased upstream or downstream flood hazard shall be created by any fill authorized in the floodplain by this chapter or other applicable chapters. (Ord. 2011-013, 2011)

14.08.320 Standards for AE and A1-30 Zones with Base Flood Elevations but No Floodways.
In areas with base flood elevations (but a regulatory flood way has not been designated), no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones A1-30 and AE on the county's FIRM, unless it is demonstrated that the cumulative effect of the proposed development when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community.

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.
