The question on the ballot
MODIFIES ENVIRONMENTAL REVIEW FOR CERTAIN PROJECTS. INITIATIVE STATUTE. Amends California Environmental Quality Act (CEQA) to expedite environmental review for specified project categories (including most housing, transportation, water, health, wildfire mitigation, educational facility, internet access, and clean energy projects). For these types of projects, this measure: Sets deadlines for public agencies to complete environmental review and take required actions. Allows expedited review of environmental impacts, limiting public agencies' current obligation to consider a range of feasible project alternatives to reduce environmental impacts. Establishes deadlines for filing and resolving lawsuits challenging project approvals; limits evidence courts may consider and relief courts can order.[1]
Creates optional new procedures for eligible "essential" projects (housing, water, health, transportation, wildfire prevention, schools, clean energy and others) under the California Environmental Quality Act. Per the Legislative Analyst: it tightens time limits for review, permits and court challenges (e.g., a 365-business-day limit to finish an environmental impact report); requires agencies to specify all application information up front and assess impacts under standards in place at application; lets the applicant develop only one project alternative; limits tribal consultation to federally recognized tribes; caps public comment periods; and narrows what courts may consider and the relief they can order, including stopping only the non-compliant part of a project. Fiscal impact: initial state and local costs likely in the high tens of millions of dollars annually, potentially over $100 million, partly covered by fees; longer-term effects uncertain and could be positive or negative.[1][2]
A YES vote means
Certain public and private projects would be eligible for new project review and court challenge procedures. For example, new procedures would tighten time limits for environmental review and reduce the scope of what courts can consider when reviewing legal challenges.
A NO vote means
Public and private projects would continue to use existing project review and court challenge procedures.
The law today
The California Environmental Quality Act (CEQA) requires agencies to consider a project's environmental effects before approval, with a more detailed environmental impact report (EIR) when significant effects cannot be avoided by minor changes. Agencies may request further information and consider new information during review, develop multiple alternatives, consult a wider range of tribes, and must allow a minimum (not maximum) public comment period. After a decision, people can sue, and a court that finds CEQA was not followed correctly can stop the whole project. Many projects also need other local and state approvals.[2]
Official fiscal estimate
Per the Legislative Analyst: initial costs for state and local governments, including courts, "likely would be in the high tens of millions of dollars annually, potentially exceeding $100 million annually," partly offset by fees; longer-term effects (faster or more projects, possible costs from approved projects with negative environmental impacts) are uncertain but could be more substantial.[2]
Arguments made for
- Official argument in favor, signed by Ann-Louise Kuhns (California Children's Hospital Association), Jennifer Capitolo (California Water Association) and Jenna Abbott (California Council on Affordable Housing): "Prop. 45 does not exempt a single project from environmental review." It "streamlines approvals by setting enforceable timelines for project approvals" and creates "a faster, more predictable process for legal challenges."[3]
- Same argument: "Permitting delays add more than $75,000 to the cost of a new home," and "cities and counties retain full authority to approve or deny projects."[3]
Arguments made against
- Official argument against, signed by Joe Lyou (Coalition for Clean Air), Jennifer Clary (Clean Water Action) and Matt Abularach-Macias (California Environmental Voters): "Proposition 45 limits both the environmental review of major new development projects and the public's right to be heard."[3]
- Same argument: "Prop. 45 reduces public agency requirements to consider public comments on proposed projects," and it "doesn't include any requirement to lower your housing costs or your utility bills."[3]
