The subdivider shall improve, or agree to improve, all streets or highways in the subdivision. Improvements shall be installed to permanent line and grade to the satisfaction of the county engineer in accordance with standard specifications of the county on file in the office of the county engineer. The minimum improvements which the subdivider makes, or agrees to make, prior to acceptance and approval of the final map or parcel map shall be:
A.
Pavement Requirements. The minimum requirements for street improvements shall be three inches of road mixed asphalt surfacing or three inches of asphalt concrete as specified in Section 38 and 39 of the standard specifications of Inyo County. The aforesaid pavements shall be placed on an aggregate base as specified in Section 26 of the standard specifications.
B.
Grading, curbs, sidewalks, gutters and cross gutters, drainage and drainage structures necessary to the proper use and drainage of streets and highways and to the public safety shall be provided. Curbs, gutters and cross gutters shall be required on districts zoned R-l, R-2, R-3, R.M.H. and C-l, C-2 and C-3. The advisory agency may waive the requirements of curbs, gutters and sidewalks if topography or any other conditions make such improvements unreasonable or impractical.
C.
A water system shall be required for all final maps; the water system shall meet the requirements of the county and shall be installed with mains of sufficient size and having a sufficient number of outlets to furnish adequate domestic water supply as required by the Uniform Building Code for each lot of a final map and to provide adequate fire protection as required by the county fire marshal to meet local neighborhood needs, including fire hydrants and laterals therefor. For four or less lots, adequate fire protection as required by the county fire marshal including fire hydrants and laterals therefor shall be required when a fire protection system is reasonably available near the subdivision.
D.
A central sewage collection system will be provided for each subdivision containing five or more lots. For four or less lots, sanitary sewer facilities will be provided where an outfall sewer is reasonably available. However, the advisory agency may waive the requirements of this section upon a showing of good cause that the waiver would not pose any long term sewage disposal problems on any of the lots in question.
E.
Services from public utilities, where provided, and from sanitary sewers shall be made available for each lot in such manner as will obviate the necessity for disturbing the street pavement, gutter, culvert and curb, when service connections are made. Final street and sidewalk surfacing shall not be completed until all utility facilities have been
F.
Utility Installations. Utility lines, including, but not limited to, electric, communications, street lighting and cable television shall be required to be placed underground for all final maps. The subdivider is responsible for complying with the requirements of this section, and he shall make the necessary arrangements with the utility companies for the installation of such facilities. For the purposes of this section, appurtenances and associated equipment in an underground system may be placed aboveground but not in the public right-of-way. The advisory agency may waive the requirements of this section if topographical, soil or any other conditions make such underground installations unreasonable or impractical. This section shall not apply to utility lines which do not provide service to the area being subdivided.
