(

a) Local ordinances may require a tentative map where a parcel map is required by this chapter. A parcel map shall be required for subdivisions as to which a final or parcel map is not otherwise required by this chapter, unless the preparation of the parcel map is waived by local ordinance as provided in this section. A parcel map shall not be required for either of the following:

(1) Subdivisions of a portion of the operating right-of-way of a railroad corporation, as defined by

Section of the Public Utilities Code, that are created by short-term leases (terminable by either party on not more than days’ notice in writing).

(2) Land conveyed to or from a governmental agency, public entity, public utility, or for land conveyed to a subsidiary of a public utility for conveyance to that public utility for rights-of-way, unless a showing is made in individual cases, upon substantial evidence, that public policy necessitates a parcel map. For purposes of this subdivision, land conveyed to or from a governmental agency shall include a fee interest, a leasehold interest, an easement, or a license. (

b) A local agency shall, by ordinance, provide a procedure for waiving the requirement for a parcel map, imposed by this division, including the requirements for a parcel map imposed by

Section 66426. The procedure may include provisions for waiving the requirement for a tentative and final map for the construction of a condominium project on a single parcel.

The ordinance shall require a finding by the legislative body or advisory agency, that the proposed division of land complies with requirements established by this division or local ordinance enacted pursuant thereto as to area, improvement and design, floodwater drainage control, appropriate improved public roads, sanitary disposal facilities, water supply availability, environmental protection, and other requirements of this division or local ordinance enacted pursuant thereto.

In any case, where the requirement for a parcel map is waived by local ordinance pursuant to this section, a tentative map may be required by local ordinance. (

c) If a local ordinance does not require a tentative map where a parcel map is required by this division, the subdivider shall have the option of submitting a tentative map, or if he or she desires to obtain the rights conferred by

Chapter 4.5 (commencing with

Section 66498.1), a vesting tentative map.
