The EIR path: process, timeline, cost and litigation risk

When no exemption applies and impacts can't be mitigated below significance, CEQA (Pub. Res. Code §§ 21000–21189.91) requires a full environmental impact report — the most expensive document in California land use. The process is choreographed step by step in the CEQA Guidelines, but the choreography understates the calendar: the Guidelines' own one-year completion target is routinely missed by a year or more.

For underwriting, an EIR is three stacked risks: schedule (18–30 months for contested urban projects), cost (seven figures all-in with technical studies and counsel), and litigation (a petition window that opens the day the Notice of Determination is filed). The clocks compound — the Permit Streamlining Act's approval deadlines don't start until CEQA review is complete, so the EIR sits on the critical path of everything else.

The path is linear on paper and iterative in practice: each handoff below is a decision point where the document can be expanded, contested, or — the schedule killer — recirculated.

• Initial study: screens whether impacts can be mitigated below significance; if not, an EIR is required.
• Notice of Preparation + scoping: agencies and the public frame what the Draft EIR must analyze — a thin scoping record invites later failure-to-study claims.
• Draft EIR: circulated for public review, typically a 45-day window.
• Final EIR: written responses to every substantive comment received.
• Certification + findings: the decision body certifies adequacy and adopts findings on each significant impact — plus a statement of overriding considerations for any impact left significant and unavoidable.
• Notice of Determination: filing starts a 30-day statute of limitations on CEQA challenges (§§ 21167 et seq.); without a filed NOD the window stretches to 180 days.

• Underwriting watch-outs:
• Recirculation is the hidden schedule bomb — significant new information added after the Draft EIR reopens public review, and late project changes are the usual trigger. Freeze the project description early.
• Responses to comments are where EIRs are won or lost in court; budget real consultant and counsel hours for the comment mountain, not a form-letter pass.
• The statement of overriding considerations is a political act, not a technical one — count the council votes before underwriting an unavoidable-impact project.

Guidelines § 15108 directs the lead agency to complete and certify an EIR within one year of accepting the application as complete. Contested urban projects actually run 18–30 months from kickoff to certification, and all-in cost — the EIR consultant, traffic/air/GHG/noise technical studies, peer review, counsel, and agency cost-recovery deposits — routinely reaches seven figures. Only after certification do the Permit Streamlining Act approval clocks begin (see the deadlines guide), so every EIR month is a critical-path month.

• Underwriting watch-outs:
• The agency's consultant procurement alone can eat a quarter before analysis starts — ask at application who is under contract.
• Model cycles drive the tail: one round of traffic or air-quality re-runs after a project tweak costs months.
• Land carry belongs in the CEQA line — 18–30 months of taxes, insurance and option payments is often the biggest "EIR cost."
• The one-year target has no practical enforcement teeth; negotiated milestone schedules with staff are worth more than the regulation.

A CEQA petition is fought on the administrative record — assembling, certifying and paying for it is its own battle — and an EIR's adequacy is reviewed for substantial evidence, a deferential standard that protects well-documented conclusions while punishing analytical gaps and procedural fouls. Remedies are not all-or-nothing: § 21168.9 lets courts sever, ordering partial decertification of the defective analysis while leaving valid approvals intact. At the top of the market, projects certified as environmental leadership development projects (the AB 900/SB 7 track) get judicial streamlining with a goal of resolving CEQA challenges, appeals included, within 270 days.

The practical de-risking play is tiering: build off a program EIR (§ 15168) or a specific plan's certified EIR so project-level review narrows to what the program document didn't already study — and qualifying residential projects implementing such a specific plan can be exempt outright under § 65457 of the planning law. Siting inside an already-studied plan area converts EIR risk into consistency analysis. And on infill sites, the best EIR strategy is not needing one — work the exemption architecture before committing to the full path.
