(a) The planning commission shall adopt rules and regulations governing the subdivision or consolidation of land, including the procedure and conditions precedent to approval thereof.
(b) All regulations when adopted as provided by law shall have the force and effect of law. Such regulations may be amended or repealed by the same process required for original adoption.
(c) Such regulations may provide for the coordination of streets within subdivisions with existing streets, planned streets, and other features of the general plan and development plans of the city, or with projected street patterns for adjoining land areas; for compliance with the general plan and development plans; for adequate and convenient open spaces for traffic, recreation, light, and air, and for a distribution of traffic and population, which will tend to create conditions favorable to health, safety, convenience, and prosperity.
(d) Such regulations may include provisions for the minimum right-of-way and pavement widths of streets or roadways within the subdivision to serve the subdivision or to provide access thereto, the extent to which and the manner in which streets and other ways shall be graded and improved, and requirements and standards of construction for street lighting, sidewalks, and shoulder areas, curbs, gutters, sanitary sewers, storm drains, flood control, street name signs, traffic signs, and other utilities and facilities to be provided or installed to and within a subdivision or consolidation, as conditions precedent to the approval of a subdivision or consolidation map.
(e) The regulations may provide that a subdivider, before submitting the subdivider’s final map for approval, may submit a preliminary map, showing the proposed subdivision or consolidation in a general way, but not necessarily indicating monuments and other survey points in detail, and that the director may give such preliminary map tentative approval, with or without modifications suggested by the director or agreed upon by the applicant. Such tentative approval shall not be entered on the map nor constitute approval of the map for recording.
(f) The regulations may require the filing of construction plans for improvements to be constructed, and the construction of improvements as conditions precedent to final approval.
(g) The regulations may provide that in lieu of the completion of the improvements, utilities, and facilities in such subdivision or consolidation before approval of the map for recordation, and subject to any conditions which the commission may provide in such rules and regulations, the director may accept a bond or bonds, with surety, or other security deemed sufficient by the director and the manager of the board of water supply to secure the city and the board of water supply the actual construction and installation of such improvements, utilities and facilities at a time and according to specifications fixed by or in accordance with the regulations of the commission and the board of water supply.
(h) The regulations may provide for the granting of modifications by the director from the construction standards and requirements in the subdivision rules and regulations where the director finds that the land proposed to be subdivided or consolidated is of such size or shape or is affected by such topographical location or condition or is to be devoted to such uses that it is impossible or impracticable in the particular case for the subdivider to conform fully to the provisions of the regulations; provided that such modifications shall not be contrary to the intent and purpose of the subdivision rules and regulations.
