66452.6.  (a) (1) An approved or conditionally approved tentative map shall expire 24 months after its approval or conditional approval, or after any additional period of time as may be prescribed by local ordinance, not to exceed an additional 24 months. However, if the subdivider is required to expend two hundred thirty-six thousand seven hundred ninety dollars ($236,790) or more to construct, improve, or finance the construction or improvement of public improvements outside the property boundaries of the tentative map, excluding improvements of public rights-of-way that abut the boundary of the property to be subdivided and that are reasonably related to the development of that property, each filing of a final map authorized by Section 66456.1 shall extend the expiration of the approved or conditionally approved tentative map by 48 months from the date of its expiration, as provided in this section, or the date of the previously filed final map, whichever is later. The extensions shall not extend the tentative map more than 10 years from its approval or conditional approval. However, a tentative map on property subject to a development agreement authorized by Article 2.5 (commencing with Section 65864) of Chapter 4 of Division 1 may be extended for the period of time provided for in the agreement, but not beyond the duration of the agreement. The number of phased final maps that may be filed shall be determined by the advisory agency at the time of the approval or conditional approval of the tentative map.(2) Commencing January 1, 2012, and each calendar year thereafter, the amount of two hundred thirty-six thousand seven hundred ninety dollars ($236,790) shall be annually increased by operation of law according to the adjustment for inflation set forth in the statewide cost index for class B construction, as determined by the State Allocation Board at its January meeting. The effective date of each annual adjustment shall be March 1. The adjusted amount shall apply to tentative and vesting tentative maps whose applications were received after the effective date of the adjustment.(3) “Public improvements,” as used in this subdivision, include traffic controls, streets, roads, highways, freeways, bridges, overcrossings, street interchanges, flood control or storm drain facilities, sewer facilities, water facilities, and lighting facilities.(b) (1) The period of time specified in subdivision (a), including any extension thereof granted pursuant to subdivision (e), shall not include any period of time during which a development moratorium, imposed after approval of the tentative map, is in existence. However, the length of the moratorium shall not exceed five years.(2) The length of time specified in paragraph (1) shall be extended for up to three years, but in no event beyond January 1, 1992, during the pendency of any lawsuit in which the subdivider asserts, and the local agency that approved or conditionally approved the tentative map denies, the existence or application of a development moratorium to the tentative map.(3) Once a development moratorium is terminated, the map shall be valid for the same period of time as was left to run on the map at the time that the moratorium was imposed. However, if the remaining time is less than 120 days, the map shall be valid for 120 days following the termination of the moratorium.(c) The period of time specified in subdivision (a), including any extension thereof granted pursuant to subdivision (e), shall not include the period of time during which a lawsuit involving the approval or conditional approval of the tentative map is or was pending in a court of competent jurisdiction, if the stay of the time period is approved by the local agency pursuant to this section. After service of the initial petition or complaint in the lawsuit upon the local agency, the subdivider may apply to the local agency for a stay pursuant to the local agency’s adopted procedures. Within 40 days after receiving the application, the local agency shall either stay the time period for up to five years or deny the requested stay. The local agency may, by ordinance, establish procedures for reviewing the requests, including, but not limited to, notice and hearing requirements, appeal procedures, and other administrative requirements.(d) The expiration of the approved or conditionally approved tentative map shall terminate all proceedings and no final map or parcel map of all or any portion of the real property included within the tentative map shall be filed with the legislative body without first processing a new tentative map. Once a timely filing is made, subsequent actions of the local agency, including, but not limited to, processing, approving, and recording, may lawfully occur after the date of expiration of the tentative map. Delivery to the county surveyor or city engineer shall be deemed a timely filing for purposes of this section.(e) Upon application of the subdivider filed before the expiration of the approved or conditionally approved tentative map, the time at which the map expires pursuant to subdivision (a) may be extended by the legislative body or by an advisory agency authorized to approve or conditionally approve tentative maps for a period or periods not exceeding a total of six years. The period of extension specified in this subdivision shall be in addition to the period of time provided by subdivision (a). Before the expiration of an approved or conditionally approved tentative map, upon an application by the subdivider to extend that map, the map shall automatically be extended for 60 days or until the application for the extension is approved, conditionally approved, or denied, whichever occurs first. If the advisory agency denies a subdivider’s application for an extension, the subdivider may appeal to the legislative body within 15 days after the advisory agency has denied the extension.(f) For purposes of this section, a development moratorium includes a water or sewer moratorium, or a water and sewer moratorium, as well as other actions of public agencies that regulate land use, development, or the provision of services to the land, including the public agency with the authority to approve or conditionally approve the tentative map, which thereafter prevents, prohibits, or delays the approval of a final or parcel map. A development moratorium shall also be deemed to exist for purposes of this section for any period of time during which a condition imposed by the city or county could not be satisfied because of either of the following:(1) The condition was one that, by its nature, necessitated action by the city or county, and the city or county either did not take the necessary action or by its own action or inaction was prevented or delayed in taking the necessary action before expiration of the tentative map.(2) The condition necessitates acquisition of real property or any interest in real property from a public agency, other than the city or county that approved or conditionally approved the tentative map, and that other public agency fails or refuses to convey the property interest necessary to satisfy the condition. However, nothing in this subdivision shall be construed to require any public agency to convey any interest in real property owned by it. A development moratorium specified in this paragraph shall be deemed to have been imposed either on the date of approval or conditional approval of the tentative map, if evidence was included in the public record that the public agency that owns or controls the real property or any interest therein may refuse to convey that property or interest, or on the date that the public agency that owns or controls the real property or any interest therein receives an offer by the subdivider to purchase that property or interest for fair market value, whichever is later. A development moratorium specified in this paragraph shall extend the tentative map up to the maximum period as set forth in subdivision (b), but not later than January 1, 1992, so long as the public agency that owns or controls the real property or any interest therein fails or refuses to convey the necessary property interest, regardless of the reason for the failure or refusal, except that the development moratorium shall be deemed to terminate 60 days after the public agency has officially made, and communicated to the subdivider, a written offer or commitment binding on the agency to convey the necessary property interest for a fair market value, paid in a reasonable time and manner.(Amended by Stats. 2021, Ch. 162, Sec. 3. (SB 9) Effective January 1, 2022.)
