SB 1326 amends two CEQA provisions (Public Resources Code §§21074 and 21084.3) to broaden what counts as a tribal cultural resource and to tighten how lead agencies must respond when a project may harm those resources. The bill explicitly adds Native American Heritage Commission–identified sacred places and entries on local tribal registers to the statutory definition, and it clarifies that tribal cultural resources are a distinct category from archaeological resources.
On process and remedies, SB 1326 moves CEQA away from a permissive “when feasible” approach and toward affirmative duties: lead agencies must adopt mitigation measures to avoid or minimize significant adverse impacts to tribal cultural resources, consider avoidance and in-place preservation when requested by a consulting tribe, document with substantial evidence why avoidance is infeasible, and incorporate culturally appropriate measures proposed by the tribe to the extent feasible. The bill also constrains curation and requires agencies to explain, in environmental documents, when they decline to use tribal methods or traditional knowledge.
At a Glance
What It Does
SB 1326 revises the CEQA definition of tribal cultural resources to include NAHC-identified sacred places and local tribal registers, and requires lead agencies to adopt mitigation measures to avoid or minimize significant adverse impacts to tribal cultural resources, with a documented substantial-evidence basis if avoidance is not used.
Who It Affects
Lead agencies (cities, counties, special districts), project applicants and developers, California Native American tribes and the Native American Heritage Commission, cultural-resource consultants, and repositories that curate tribal materials.
Why It Matters
The bill elevates tribal requests for avoidance and preservation and embeds tribal expertise into CEQA decision-making, increasing the legal and evidentiary obligations on agencies and likely shifting mitigation choices (and costs) toward culturally informed approaches.

What This Bill Actually Does
SB 1326 makes three linked changes to how CEQA treats tribal cultural resources. First, it expands the statutory definition so that a tribal cultural resource can be a site, place, landscape, sacred place, or object that the Native American Heritage Commission identifies as a sacred place or that appears on a local tribal register.
That change recognizes formal NAHC designations and locally curated tribal lists as qualifying evidence for CEQA protection.
Second, and more consequential for how projects proceed, the bill rewrites the mitigation standard. Where current law asks agencies to “when feasible” avoid damage to tribal cultural resources and lists mitigation examples, SB 1326 directs agencies to adopt mitigation measures to avoid or minimize significant adverse impacts.
The statute keeps the illustrative list of measures—avoidance and in-place preservation, culturally appropriate treatment, conservation easements, reburial or relocation on the property, relinquishment to the tribe, and tribal access or comanagement—but changes the agency obligation from permissive to prescriptive and requires agencies to treat avoidance as a primary option when the consulting tribe requests it.Third, the bill tightens documentation and deference rules. If an agency concludes avoidance or in-place preservation is infeasible, it must record and support that conclusion with substantial evidence in the administrative record and then incorporate other measures consistent with CEQA.
The consulting tribe may propose culturally appropriate mitigation and treatment measures, and agencies must consider and, to the extent feasible, incorporate those proposals. The bill also requires agencies to explain in project environmental documents if they choose not to use tribal methods, standards, or traditional knowledge for identification, avoidance, mitigation, or treatment of tribal cultural resources.
Finally, curation at repositories is permitted only with tribal agreement and subject to repatriation law and fees, signaling stronger tribal control over the disposition of excavated materials.
The Five Things You Need to Know
SB 1326 amends Public Resources Code §21074 to add NAHC-identified sacred places and resources listed on local tribal registers to the definition of "tribal cultural resources.", The bill rewrites §21084.3 to require lead agencies to adopt mitigation measures to avoid or minimize significant adverse impacts to tribal cultural resources, instead of merely considering avoidance "when feasible.", When a consulting tribe requests avoidance and in-place preservation, the lead agency must consider it; if the agency deems avoidance infeasible it must demonstrate and document that finding with substantial evidence in the record.
The consulting tribe may identify culturally appropriate mitigation or treatment measures, and the lead agency must consider and incorporate those measures to the extent feasible; agencies must explain in environmental documents why they did not use tribal methods or traditional knowledge.
Curation of tribal cultural resources at repositories may occur only if the consulting tribe agrees; any curation remains subject to federal/state repatriation laws and repository fees.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Expands the definition of tribal cultural resources and distinguishes tribal methods
This amendment broadens what qualifies as a tribal cultural resource by adding resources the Native American Heritage Commission has identified as sacred places and resources included in a local tribal register. Practically, this gives agencies an additional, statutory basis for treating certain places as protected TCRs during review. The section also reiterates that tribal cultural resources are a separate category from general archaeological resources and adds a procedural requirement: if the lead agency decides not to use tribal methods, standards, or traditional knowledge to identify TCRs, it must explain that choice in the environmental documents with supporting substantial evidence. That explanation becomes part of the administrative record and can be challenged in litigation.
From permissive avoidance to required mitigation
SB 1326 replaces the softer instruction that agencies “shall, when feasible, avoid damaging effects” with a requirement that lead agencies adopt mitigation measures to avoid or minimize significant adverse impacts to TCRs when a project may cause substantial adverse change. The bill preserves the list of example measures—avoidance/preservation, culturally appropriate treatment, conservation easements, reburial or relocation on-site, relinquishment to tribe, and access for cultural practices—but recasts these as mitigation options agencies must consider and, where feasible, implement.
Obligation to prioritize avoidance and to consider tribal proposals
When a consulting tribe requests avoidance and preservation in place, the lead agency must consider that request. If the agency concludes avoidance is not feasible, it must document and support that conclusion with substantial evidence and then adopt other measures to avoid or minimize impacts. The consulting tribe may propose culturally appropriate mitigation and treatment measures; the agency must consider and, to the extent feasible, incorporate those proposals into mitigation plans. This creates a statutory path for tribal input to shape both whether avoidance occurs and what alternative protections are adopted.
Curation limits and reaffirming tribal expertise
Curation of TCRs at repository facilities requires the tribe's agreement and remains subject to federal/state repatriation law and repository fees; this limits unilateral curation decisions by agencies or applicants. The section also repeats that archaeological methods may not always fit TCRs and requires agencies to explain in environmental documents when they decline tribal methods or traditional knowledge for adoption of avoidance, mitigation, or treatment—again creating an evidentiary posture that can be scrutinized in CEQA litigation.
Fiscal note: no state reimbursement required
The bill declares no state reimbursement under Article XIII B, section 6 because local agencies have authority to levy fees sufficient to pay for any mandated program. This is a standard clause that addresses the fiscal-mandate question rather than defining CEQA obligations; it signals the Legislature expects local agencies and project proponents to absorb costs through existing fee mechanisms.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- California Native American tribes: They gain statutory recognition for NAHC-identified sacred places and local tribal registers, stronger standing in CEQA consultation, and explicit authority to propose culturally appropriate mitigation, access, relinquishment, reburial, or comanagement arrangements.
- Tribal cultural preservation advocates and local historical preservation groups: Expanded definition and affirmative mitigation duties increase the likelihood that cultural landscapes and non‑archaeological tribal values are protected in planning and project design.
- Communities near sensitive sites: When preservation in place or conservation easements are used, local communities benefit from maintained cultural landscapes, publicly accessible green space, or enhanced stewardship commitments tied to development projects.
Who Bears the Cost
- Lead agencies (cities, counties, special districts): Agencies must adopt mitigation measures, create an evidentiary record if avoidance is infeasible, and explain refusal to use tribal methods—tasks that increase staff time, consultant work, and potential litigation exposure.
- Project applicants and developers: Expect higher compliance costs (redesign, conservation easements, stewardship commitments, on‑site reburial logistics, or relinquishment agreements) and potential schedule delays as agencies and tribes negotiate mitigation and documentation.
- Curation repositories and museums: The requirement that curation occur only with tribal agreement could constrain standard repository practices, shift storage or repatriation costs, and require renegotiation of fees and custody arrangements.
Key Issues
The Core Tension
The central dilemma is between stronger, culturally informed protection of tribal cultural resources—recognizing tribal expertise and prioritizing avoidance—and the administrative, financial, and scheduling burdens placed on lead agencies and project proponents; protecting irreplaceable cultural values often requires design changes, land use constraints, or costs that can conflict with development objectives and statutory permitting frameworks.
SB 1326 tightens CEQA obligations in ways that will be practical in some cases and legally fraught in others. The switch from a permissive “when feasible” formulation to a directive that agencies adopt mitigation measures creates questions about timing and scope: must an agency adopt avoidance-oriented mitigation earlier in project design, and at what point does the obligation transform into a veto right? "Substantial evidence" is the statutory evidentiary standard the bill uses to validate an agency’s finding that avoidance is infeasible, but that term carries litigation-ready weight—challengers can demand the administrative record show the empirical basis for feasibility conclusions, increasing the risk of CEQA lawsuits and the administrative burden on agencies.
The bill’s deference to tribal-identified mitigations and requirement that agencies explain nonuse of tribal methods also raises implementation questions. "Incorporate to the extent feasible" and "consider" leave room for negotiation, but those phrases will be litigated: courts will have to decide when an agency properly balanced tribal proposals against project needs, public safety, or statutory obligations. The curation constraint—permitting repository storage only with tribal consent—aligns repository practice with tribal sovereignty but may complicate compliance where federal repatriation law or existing contracts impose different duties.
Finally, the statute tightens protections without articulating specific timelines or funding for compliance, so agencies may face pressure to allocate staff and consulting dollars or to rely on applicants for additional mitigation funding.
