Pub. Resources Code, § 21155.2

(a) A transit priority project that has incorporated all feasible mitigation measures, performance standards, or criteria set forth in the prior applicable environmental impact reports and adopted in findings made pursuant to Section 21081, shall be eligible for either the provisions of subdivision (b) or (c).

(b) A transit priority project that satisfies the requirements of subdivision (a) may be reviewed through a sustainable communities environmental assessment as follows:

(1) An initial study shall be prepared to identify all significant or potentially significant impacts of the transit priority project, other than those which do not need to be reviewed pursuant to Section 21159.28 based on substantial evidence in light of the whole record. The initial study shall identify any cumulative effects that have been adequately addressed and mitigated pursuant to the requirements of this division in prior applicable certified environmental impact reports. Where the lead agency determines that a cumulative effect has been adequately addressed and mitigated, that cumulative effect shall not be treated as cumulatively considerable for the purposes of this subdivision.

(2) The sustainable communities environmental assessment shall contain measures that either avoid or mitigate to a level of insignificance all potentially significant or significant effects of the project required to be identified in the initial study.

(3) A draft of the sustainable communities environmental assessment shall be circulated for public comment for a period of not less than 30 days. Notice shall be provided in the same manner as required for an environmental impact report pursuant to Section 21092.

(4) Prior to acting on the sustainable communities environmental assessment, the lead agency shall consider all comments received.

(5) A sustainable communities environmental assessment may be approved by the lead agency after conducting a public hearing, reviewing the comments received, and finding that:

(A) All potentially significant or significant effects required to be identified in the initial study have been identified and analyzed.

(B) With respect to each significant effect on the environment required to be identified in the initial study, either of the following apply:

(i) Changes or alterations have been required in or incorporated into the project that avoid or mitigate the significant effects to a level of insignificance.

(ii) Those changes or alterations are within the responsibility and jurisdiction of another public agency and have been, or can and should be, adopted by that other agency.

(6) The legislative body of the lead agency shall conduct the public hearing or a planning commission may conduct the public hearing if local ordinances allow a direct appeal of approval of a document prepared pursuant to this division to the legislative body subject to a fee not to exceed five hundred dollars ($500).

(7) The lead agency’s decision to review and approve a transit priority project with a sustainable communities environmental assessment shall be reviewed under the substantial evidence standard.

(c) A transit priority project that satisfies the requirements of subdivision (a) may be reviewed by an environmental impact report that complies with all of the following:

(1) An initial study shall be prepared to identify all significant or potentially significant effects of the transit priority project other than those that do not need to be reviewed pursuant to Section 21159.28 based upon substantial evidence in light of the whole record. The initial study shall identify any cumulative effects that have been adequately addressed and mitigated pursuant to the requirements of this division in prior applicable certified environmental impact reports. Where the lead agency determines that a cumulative effect has been adequately addressed and mitigated, that cumulative effect shall not be treated as cumulatively considerable for the purposes of this subdivision.

(2) An environmental impact report prepared pursuant to this subdivision need only address the significant or potentially significant effects of the transit priority project on the environment identified pursuant to paragraph (1). It is not required to analyze off-site alternatives to the transit priority project. It shall otherwise comply with the requirements of this division.
