19.62.010 Legislative intent.

A. Within the county of Maui, certain areas are subject to periodic inundation by flooding or tsunami or both, resulting in loss of life and property, creation of health and safety hazards, disruption of commerce and governmental services as well as extraordinary public expenditures for flood and tsunami protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.

B. The flood losses are caused by the cumulative effect of obstructions in areas of special flood hazard that increase flood heights and velocities, and, when inadequately anchored, damage uses in other areas. Uses that are inadequately floodproofed, elevated, or otherwise protected from flood damage also contribute to flood loss.

C. Congress has determined that regulation of construction in areas subject to flood hazards is necessary for the protection of life and property and reduction of public costs for flood control, rescue and relief efforts, thereby promoting the safety, health, convenience and general welfare of the community. In order to achieve these purposes, this chapter establishes flood hazard areas and imposes restrictions upon manmade changes to improved and unimproved real estate within the areas. These restrictions are necessary to qualify the county of Maui for participation in the federal flood insurance program.

D. Failure to participate in the program would result in the denial of federal financial assistance for acquisition and construction purposes, and jeopardize the making, securing, extension, and renewal of loans secured by improved real estate by lending institutions regulated by the federal government.

E. This chapter is designed to:

1. Protect human life and health and promote the general welfare;

2. Minimize expenditure of public money for costly flood control projects;

3. Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;

4. Minimize prolonged business interruptions;

5. 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;

6. Help maintain a stable tax base by providing for the sound use and development of areas of special flood hazard;

7. Ensure that potential buyers are notified that property is in an area of special flood hazard; and

8. Ensure that those who occupy the areas of special flood hazard assume responsibility for their actions. (Ord. 2223 § 1 (part), 1993: Ord. 1145 § 2 (part), 1981)

19.62.050 Administration.

A. Special Flood Hazard Area Development Permit. A special flood hazard area development permit shall be obtained from the director before construction of any development begins within any special flood hazard area, flood-related erosion hazard area, or mudslide (i.e., mudflow) area. Application for a permit shall be made on forms furnished by the director that may require, but not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions, and elevation of the area in question, existing or proposed structures, fill, stockpiles, and drainage facilities. The application shall require the following:

1. Proposed elevation, in relation to mean sea level, of the lowest floor (including basement) of all structures. In zone AO, elevation of highest adjacent grade and proposed elevation of lowest floor of all structures;

2. Proposed elevation, in relation to mean sea level, to which any structure will be floodproofed;

3. All appropriate certifications required under section 19.62.060; and

4. Description of any anticipated watercourse alteration or relocation as a result of the proposed development.

B. Permit Review. The director shall review all permit applications to determine that the requirements of this chapter have been satisfied, that the site is reasonably safe from flooding, and that, where base flood elevations have been determined but a floodway has not been designated, the cumulative effect of the proposed development (as certified by a civil engineer) when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood by more than one foot at any point.

C. Use of Other Base Flood Data. Where base flood elevation has not been determined, the director shall obtain, review, and reasonably use any base flood elevation and floodway data available from a federal or state agency, or other source, in administering section 19.62.060.

D. Flood Map Revisions. Whenever base flood elevations may increase or decrease due to a proposed development, the owner of the property shall obtain a conditional letter of map revision (CLOMR) from the Federal Emergency Management Agency (FEMA) before the approval or issuance of any development permit or any increase or decrease of base flood elevations. A letter of map revision (LOMR) shall be obtained from FEMA whenever a development has increased or decreased the base flood elevation within any special flood hazard area. An application for a LOMR shall be submitted to FEMA no later than six months after the completion of a development.

E. Watercourse Alteration. Whenever a watercourse is to be altered or relocated, the director shall:

1. Require the applicant to notify the State of Hawaii department of land and natural resources, division of water resource management, before such alteration or relocation, and submit evidence of such notification to the Federal Insurance Administration, Federal Emergency Management Agency (FEMA);

2. Require that the flood-carrying capacity of the altered or relocated portion of the watercourse be maintained.

F. Certifications. The director shall obtain and maintain for public inspection the certifications required under section 19.62.060.

G. Boundary Determinations. The director shall determine, where needed, the exact location of boundaries of special flood hazard areas (for example, where there appears to be a conflict between a mapped boundary and actual field conditions).

1. Where interpretation is needed as to whether or not a development lies within a special flood hazard area or as to the base flood elevation affecting a development, a request for such interpretation shall be submitted to the director. The request shall include a description of the development site, a location plan showing the property lines and dimensions of the development and a copy of the tax map showing the parcel upon which the development is proposed to be constructed. The director shall, where interpretation is possible from the information shown on the FHBM or FIRM, issue written determination of the specific area boundaries and the base flood elevation.

2. Where, in the opinion of the director, interpretation is not possible from the information shown on the FHBM or FIRM, the director shall require the applicant to provide more detailed information concerning the request for determination of flood boundaries and the base flood elevation. The additional information shall be submitted to the director and shall contain a recommendation certified by a civil engineer as to the flood area and base flood elevation that should apply to the proposed development and shall include three sets of documents certified by the engineer containing adequate data consistent with this chapter, such as flood and hydrology studies, project site and location plans, property maps showing lines and dimensions, tax maps and topographic data including contours or spot heights based upon mean sea level. After review, the director shall, in writing;

a. Inform the applicant that the detailed request contains inadequate data to make a determination as to flood area boundaries and base flood elevations, and specify the specific lack of data needed to resolve the question and decline to make a determination; or

b. Based upon the supporting data submitted with the request for interpretation and other available data, determine the flood area boundaries and the base flood elevations affecting the development; or

c. Instruct the applicant to submit the request for interpretation directly to the Federal Emergency Management Agency.

3. None of the provisions of this section shall prevent an applicant from requesting an appeal or resubmitting a request for a determination of the flood area boundaries or the base flood elevations directly from the director or the Federal Emergency Management Agency. Any such written determination from the Federal Emergency Management Agency shall be sufficient in lieu of a determination from the director. (Ord. 2223 § 1 (part), 1993: Ord. 1624 § 2, 1987: Ord. 1145 § 2 (part), 1981)

Designs for meeting this requirement must be either certified by an engineer or architect or meet or exceed one of the following minimum criteria:

i. Provide a minimum of two openings, having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding, with the bottom of all openings no higher than one foot above grade. (Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwater.); or

ii. Be certified by an engineer as complying with a county floodproofing standard approved by the Federal Insurance Administration, Federal Emergency Management Agency (FEMA).

4. Building Height Allowance. Building heights in the agricultural and residential zoning districts may be increased by a height equal to the base flood, up to a maximum of five feet above the maximum building height permitted by the zoning regulations for the zoning district in which the building is located.

5. Certification shall be provided by an architect or engineer that all new construction and substantial improvements meet or exceed applicable standards for flood hazard reduction, including, but not limited to, those regarding anchoring, construction materials and methods, elevation and floodproofing, utilities, subdivisions, and manufactured homes.

B. Utilities.

1. New and replacement water supply and sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into such systems and discharge from such systems into floodwaters.

2. On-site waste disposal systems shall be located to avoid impairment to, or contamination from, such systems during flooding.

C. Subdivisions. Subdivisions proposals shall:

1. Identify any special flood hazard areas affected and the base flood elevation of such areas;

2. Provide the elevation of proposed structures and pads. If the site is filled above the base flood elevation, the final first floor and pad elevations shall be certified by an engineer or surveyor and provided to the director;

3. Be consistent with the need to minimize flood damage;

4. Have utilities, such as sewer, gas, electric, and water systems, located and constructed to minimize flood damage;

5. Provide adequate drainage to reduce exposure to flood hazards.

D. Manufactured Homes. Manufactured homes that are placed or substantially improved within special flood hazard areas that are not coastal high hazard areas shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated to, or above, the base flood elevation and be securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement. Manufactured homes that are place or substantially improved within coastal high hazard areas shall meet the requirements of subsection G of this section.

E. Recreational Vehicles. Recreational vehicles placed on sites within zones A1-30, AH, and AE, or within coastal high hazard areas, shall either:

1. Be on site for fewer than thirty consecutive days;

2. Be fully licensed and ready for highway use (a recreational vehicle is ready for highway use if it is on wheels or a jacking system, is attached to the site only by a quick disconnect type utilities and security device, and has no permanently attached additions); or

3. Meet the permit requirements of section 19.62.050 and the requirements for manufactured homes under subsection D of this section.

F. Floodways. No encroachments, including fill, new construction, substantial improvement, or other new development, shall be allowed within floodways unless certification by a civil engineer is provided to the director demonstrating that the encroachments will not result in any increases in base flood levels.

G. Coastal High Hazard Areas. Within coastal high hazard areas:

1. New construction and substantial improvements shall be elevated on adequately anchored pilings or columns and securely anchored to such pilings or columns so that the lowest horizontal portion of the structural members of the lowest floor (excluding the pilings or columns) is elevated to or above the base flood level. The pile or column foundation and the structure attached thereto shall be anchored to resist flotation, collapse, and lateral movement due to the simultaneous action of wind and water loads on all building components. Water loading values used for purposes of meeting this requirement shall be those associated with the base flood. Wind loading values used shall be those required by the Uniform Building Code, as amended.

2. New construction and substantial improvements shall be located on the landward side of the reach of mean high tide.

3. New construction and substantial improvements shall have the space below the lowest floor free of obstructions or constructed with breakaway walls. Such space shall not be used for human habitation, but shall be useable solely for vehicular parking, building access, or storage. A breakaway wall shall have a safe design loading resistance of not less than ten and no more than twenty pounds per square foot. Breakaway wall collapse shall be designed to result from a water load less than that which would occur during a base flood and the elevated portion of the building shall be designed so as not to incur any structural damage from wind and water loads acting simultaneously during a base flood.

4. Fill shall not be used for structural support of buildings.

5. Manmade alteration of sand dunes shall not increase potential flood damage.

6. The director shall be provided and shall maintain the following records:

a. Certification by an engineer or architect that the proposed structure complies with paragraphs 1 through 5 of this subsection;

Certification by a structural engineer or surveyor of the elevation (in relation to mean sea level) of the bottom of the lowest structural member of the lowest floor (excluding pilings or columns) of all new and substantially improved structures, and information regarding whether such structures contain basements. FEMA’s “elevation certificate” form, as amended, shall be used for the certification. (Ord. 2223 § 1 (part), 1993: Ord. 1743 § 2, 1988: Ord. 1624 § 3, 1987: Ord. 1292 § 2, 1983: Ord. 1145 § 2 (part), 1981)

19.62.100 Developments adjacent to drainage facilities.

A. Applications involving developments encompassing or adjoining any stream, river, or drainage facility shall be subject to review by the director. Upon determination by the director that the development may adversely affect a special flood hazard area, the application shall include information, signed and stamped by an engineer or architect in accordance with sections 19.62.050 and 19.62.060, to evaluate the potential flooding of the area.

B. The director shall not issue any permit involving modification, construction, lining, or alteration of any drainage facility, river, or stream unless such modification, construction, lining, or alteration does not reduce the capacity of the drainage facility, river, or stream, or adversely affect any downstream property. (Ord. 2223 § 1 (part), 1993: Ord. 1145 § 2 (part), 1981)

19.62.140 Variances and appeals.

A. The board of variances and appeals shall hear and decide appeals alleging an error in any requirement or determination by the director and requests for variances from the requirements of this chapter.

B. Application. Applications for variances and appeals shall conform to the requirements of chapter 19.520. The application shall be certified by an architect or engineer, and shall include three sets of the following documentation:

1. Plans and specifications showing: the site and location; dimensions of all property lines and topographic elevation of the lot; existing and proposed structures and improvements, fill, and storage areas; location and elevations of existing and proposed streets and utilities; floodproofing measures; relationship of the site to flood boundaries; and existing and proposed flood control measures and improvements.

2. Cross-sections and profile of the area and the base flood elevations based on mean sea level.

3. Flood study and drainage report.

4. Description of surrounding properties and existing structures and uses, and the effect of a base flood as a result of the variance.

6. An agreement to insert and record covenants in the conveyance and title documents of the property that the property is located in a special flood hazard area and is subject to flooding and flood damage. The covenants shall contain statements attesting to all adverse effects resulting from the variance. The covenants shall also state that the property owner or owners and assigns shall not file any lawsuit or action against the county for costs or damages or any claim, and shall indemnify and save harmless the county from any liability when such loss, damage, injury, or death results due to the flood hazard variance and flooding of the property. Upon approval of the flood hazard variance, such covenants shall be fully executed and submitted to the director for approval. Upon approval, the applicant shall file the covenants with the bureau of conveyances.

C. In passing upon variance applications, the board of variances and appeals shall consider:

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 existing owner and future owners of the property;

4. The importance of the services provided by the proposed facility to the community;

5. The necessity, if any, to the facility of a waterfront location;

6. The availability of alternative locations for the proposed use that 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 community plan and floodplain management program for that area;

9. The safety of access to the property in time of flood for ordinary and emergency vehicles;

10. The expected heights, velocity, duration, rate of rise, and sediment transport of floodwaters expected at the site;

11. The costs of providing governmental services during and after flood conditions, including maintenance and repair of utilities and facilities, such as sewer, gas, electric, and water systems, and streets and bridges.

D. Conditions for Variances.

1. Variances shall be issued only upon a determination that the variance is peculiar to the property involved and is the minimum necessary to afford relief to the applicant with minimum deviation from the requirements of this chapter.

2. Variances shall be issued only upon (a) a showing of good and sufficient cause; (b) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and (c) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, defraud or victimize the public, or conflict with existing county or state laws. Mere economic or financial hardship, or inconvenience, or aesthetic preferences, shall not, by themselves, constitute a finding of exceptional hardship.

3. Variances shall not be issued within any designated floodway if any increase in base flood levels would result.

4. Variances may be issued for new construction, substantial improvements, and other proposed new developments to be erected on a lot of one-half acre or less in size contiguous to, and surrounded by, lots with existing structures constructed below the base flood level, provided that the procedures of sections 19.62.050 and 19.62.060 have been fully considered. For lots greater than one-half acre, the technical justification required for issuing the variance shall be greater.

5. Variances may be issued for the repair or rehabilitation 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.

6. Variances may be issued for new construction, substantial improvements, and other proposed new developments necessary for the conduct of a use that cannot perform its intended purpose unless located in close proximity to water. Such uses shall include only docking facilities, port facilities necessary for the loading and unloading of cargo or passengers, and ship building and ship repair facilities (but not long-term storage or manufacturing facilities); provided that the provisions of subsection B of this section are satisfied and that the structure or other development is protected by methods that minimize base flood damage and create no additional threats to public safety.

7. Upon consideration of the factors of subsection B of this section and the purposes of this chapter, the board of variances and appeals may attach such conditions to the granting of a variance as it deems necessary to further the purposes of this chapter.

E. Any applicant to whom a variance is granted shall be given written notice over the signature of the director that (a) the issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as $25 for $100 of insurance coverage and (b) such construction below the base flood level increases risks to life and property. A copy of the notice shall be recorded by the applicant in the bureau of conveyances of the State of Hawaii in a manner that appears in the chain of title of the affected parcel.

F. The director shall maintain a record of all variance actions, including justification for their issuance, and report such variances issued in its biennial report submitted to the Federal Insurance Administration, Federal Emergency Management Agency. (Ord. 2223 § 1 (part), 1993: Ord. 1743 § 7, 1988: Ord. 1145 § 2 (part), 1981)

19.62.160 Warning and disclaimer of liability.
