Churches shall dedicate land necessary for road widening purposes to comply with the requirements of this chapter.

B. Except as provided in subsection A, improvements conforming to the requirements specified in this chapter shall be constructed as follows:

1. Where substandard existing streets are within the boundaries of a subdivision, all improvements shall be constructed upon those portions of the streets within the subdivision,

Where pavement on existing streets providing access to a subdivision is substandard in width or nonexisting, the subdivider shall install pavement to a minimum width of twenty feet in areas zoned residential, rural or agricultural and to a minimum width of twenty-four feet in areas zoned apartment, business, hotel or industrial. Shoulder areas shall be graded where necessary in residential, rural and agricultural areas, and in other areas the director may require such additional improvements as may be practicable, up to and including curbs, gutters and sidewalks.

The length of the required improvements shall be minimum of one hundred lineal feet multiplied by the number of lots in the subdivision minus one; provided, however, that where in the director’s opinion existing access streets to the subdivision are so inadequate as to imperil the public health, safety or general welfare, the subdivider shall provide the minimum conforming width of improvements required by this subsection B.3 along the entire length of the existing street providing access to the subdivision, or the director shall deny the subdivision.

A. Drainage systems in all subdivisions shall be planned, designed and constructed in accordance with standards of the department of public works or consistent with generally accepted engineering practices certified by an engineer so as to meet the following:

1. Protect and preserve existing natural drainage ways to the extent feasible;

2. Design a drainage system to be compatible with surrounding conditions;

3. Provide a system by which water within the subdivision will be removed using the natural drainage area where feasible with a minimum disruption to existing drainage patterns and without causing unnecessary harm to adjoining areas;

4. Analyze drainage requirements for each subdivision individually and take every means to insure the ability to subdivide the land within its zoning;

5. Assure that waters are drained from the subdivision in such a manner that they will not cause erosion outside of the subdivision to any greater extent than would occur in the absence of subdivision and improvements thereto;

6. Provide for the crossing of water courses by culverts rather than spanning where possible.

B. Where interior drainage systems within an area are improved, a storm drainage system shall be required in all subdivisions within that area where surface runoff cannot be adequately conveyed. Where open channels are used, the subdivider shall provide total right-of-way, including a ten foot wide maintenance road along both banks where the top channel width exceeds fifty feet, and along one bank where the top width is fifty feet or less. The director may require that maintenance roads along the channel shall be topped with six inches of crushed coral or base course and treated with bituminous material. In lieu of a maintenance road, for normally dry channels, access ramps, or other suitable alternative measures to facilitate maintenance may be provided.

B. Utility lines, including but not limited to those required for electric, telephone, street lighting, cable television services and other related facilities, shall be installed underground in all subdivisions laid out within the industrial, business, hotel, apartment and duplex areas in accordance with the applicable standards and methods employed for such underground installation by the public utility companies involved; provided, however, where a subdivision consists of three lots or less, the subdivider may, upon approval of the director, arrange to have such utility lines and related facilities installed overhead in accordance with the standards and methods employed for such overhead installation by the public utility companies. The director may require the installation of underground utilities serving the subdivision in other urban areas in order to assure compatibility with neighboring developments. The subdivider shall be responsible for making the necessary arrangements with government agencies and the public utility companies concerned for the installation of such utility lines and related facilities in accordance with the requirements of this chapter.

C. The provisions of this section shall not apply to the following types of utility lines and related facilities:

1. Pedestals used exclusively for police and fire alarm boxes, traffic-control facilities, street lighting, or similar equipment belonging to or operated by either the state or the county;

4. Electric distribution transformers and related switching and protective equipment mounted on pads;

5. Electric distribution circuits of the twelve kilovolt class supported by metal poles without crossarm; and

6. Communication distribution terminals and television cable apparatuses mounted on pads or aboveground pedestals.

D. Whenever the strict application of the requirements of this section would be impractical because of the nature of the surface, subsurface or topographical conditions of the property to be subdivided, the board of adjustment and appeals may approve such modification thereof as is reasonably necessary in the interest of the public and not contrary to the intent and purposes of this chapter. Before making any such modification, the board of adjustment and appeals shall refer the request for any such modification to the director of public works and the director for their recommendations.

electrical and other utility facilities proposed to be installed in the subdivision.

B. The subdivider shall indicate the location of required traffic signs on the construction plans. The construction plans shall also clearly indicate that the power to stop construction work is vested with the county through the director of public works or the director of water supply. The construction plans shall be drawn on acceptable tracing medium to county standards as to size and general drafting practice. Included with the construction plans shall be a general layout map showing the location of lots and streets, and the location of water lines, sewer mains and drainage systems and other utility lines.

B. The subdivider shall be notified of any changes or deficiencies or additional requirements in the construction plans within forty-five calendar days of submission to the director. If no action is taken by the director within this period, or such longer period as may have been agreed upon in writing, then the plans shall be deemed approved as submitted and it shall be the duty of the director, the director of public works and the director of water supply to affix their approval thereon.

C. The approval of the construction plans by the director shall not relieve the subdivider nor the engineer of the responsibility for any and all defects that may become evident subsequent to the plan's approval. Should there be any errors or omissions, then the construction plans and construction work shall be codified as requested by the director of public works and/or the director of water supply.

The director of public works shall not issue a building permit, and the director of water supply shall not approve of water service, for the subject property or any subdivided parcel thereof unless the requirements set forth in this chapter are fully complied with.

C. Agreement. The provisions of this section shall be implemented through an agreement between the department of public works, the department of water supply, the owners of the property and the transferee(s), and the conditions imposed by this section shall run with the land and shall bind and constitute notice to all subsequent grantees, assignees, mortgagees, lienors and other persons who claim an interest in the subject property. The agreement shall be in recordable form and recorded with the bureau of conveyances of the State of Hawaii or the land court of the State of Hawaii, or both.

D. Notice Required. The conveyance document(s) to the intended transferee(s) shall be submitted to the county prior to final subdivision approval. The document(s) shall contain a reference to the agreement required by this section, including a specific reference to the prohibition on the issuance of building permits and water meters.

E. Signatures Required. No application for subdivision approval under this section shall be approved unless all owners of the property and all designated transferees execute the agreement referred in subsection C of this section. (Ord. 1656 § 1, 1987)
