01 · Workflow foundations

Understand the CEQA review lifecycle before automating

CEQA reviews span multiple hand-offs, expert inputs, and compliance checkpoints. Trace the current state to identify where automation improves speed and consistency, and where human judgment must stay primary.

01

Pre-screen & intake

Collect project descriptions, entitlements, GIS layers, and prior approvals. Determine CEQA pathway (exemption, addendum, IS/MND, EIR) and critical deadlines.

  • Normalize document formats (PDF, CAD exports, spreadsheets)
  • Flag missing supporting studies or inconsistencies
  • Auto-build project metadata sheet (APNs, jurisdiction, lead agency)
02

Initial Study & Appendix G

Baseline environmental setting, impact screening, and determination of significance thresholds.

  • Auto-tag Appendix G topics across source documents
  • Summarize baseline conditions from technical attachments
  • Highlight potential triggers for focused studies
03

Technical studies

Coordinate specialists (air quality, traffic, bio, cultural) and synthesize findings into consistent determinations.

  • Detect mismatched assumptions across studies
  • Extract mitigation measures directly from consultant reports
  • Surface data gaps before formal review
04

Draft document assembly

Prepare IS/MND or Draft EIR chapters, appendices, and findings.

  • Generate chapter outlines aligned to agency templates
  • Link source citations and figures automatically
  • Produce reviewer checklists for each chapter
05

Public review & responses

Intake comment letters, prepare responses to comments (RTC), and track issues raised.

  • Cluster comments by Appendix G topic and concern level
  • Draft response templates with citations to supporting sections
  • Generate task assignments and due dates for SMEs
06

Finalization & monitoring

Issue Final EIR/IS, adopt findings, and translate mitigations into monitoring programs.

  • Auto-create Mitigation Monitoring and Reporting Program (MMRP) registers
  • Assign responsible departments and timelines
  • Version-control approvals and council/board actions
02 · Value targeting

Focus on automation that unlocks measurable time savings

Target repeatable, document-heavy tasks first. Pair every automation with a human-review checkpoint so your team stays confident signing certifications and findings.

Document intake QA

Automatically clean, OCR, and classify incoming files.

  • Detect missing pages, illegible scans, or redaction issues

  • Flag cumulative impact references needing cross-checks
  • Alert team to required consultations (CDFW, SHPO, tribal)

Drafting & templating

Use large language models (LLMs) fine-tuned on prior CEQA documents to scaffold narratives.

  • Generate Initial Study sections with citations to source excerpts
  • Style mitigation measures per agency boilerplate
  • Auto-build executive summaries and findings tables

Technical study QA

Cross-validate consultant deliverables to ensure consistency.

  • Compare assumptions (traffic growth, AQ modeling inputs)
  • Spot outdated references to regulations or handbooks
  • Generate reviewer questions for subject-matter experts

Comment response matrix

Classify, cluster, and draft responses to comment letters.

  • Auto-generate Response to Comment IDs and master log
  • Suggest citations to relevant Draft EIR sections
  • Track commitments requiring technical updates

Mitigation monitoring

Translate measures into action-ready tasks with owners and triggers.

  • Sync with permitting, capital projects, or asset management tools
  • Push calendar reminders and inspection checklists
  • Track mitigation effectiveness metrics in dashboards
03 · Reference architecture

Combine proven CEQA workflows with AI components that keep humans in the loop. Favor auditable models, deterministic pipelines, and structured outputs for legal defensibility.

Data layer

  • Document repository (SharePoint, AWS S3, Google Drive)
  • GIS services (ArcGIS Online, OpenStreetMap extracts)
  • Open datasets (CalEnviroScreen, SCAG, CARB inventories)
  • Prior CEQA determinations for fine-tuning

Intelligence layer

  • OCR & document parsing (Tesseract, AWS Textract, Azure Form Recognizer)
  • Vector store or knowledge graph for semantic retrieval
  • LLM or rules engine for drafting and QA (OpenAI, Anthropic, LLaMA hosted)
  • Prompt templates with citations and guardrails

Workflow layer

  • Orchestration (Airflow, Prefect, n8n, Zapier Enterprise)
  • CEQA review dashboard with status tracking
  • Redlining & collaboration (Word online, Adobe, Hypothes.is)
  • Audit log + outputs pushed back into document management

Security & compliance checklist

  • Maintain chain-of-custody logs for every AI-assisted output
  • Store sensitive environmental data in region-specific infrastructure
  • Document prompts, model versions, and parameter sets for each deliverable
  • Enforce human approval on determinations of significance and mitigation commitments

Role assignments

05 · Runbook

Execute the automated CEQA review pipeline

Use this repeatable sequence for each project. Tune prompts, thresholds, and hand-offs based on resource area complexity and stakeholder sensitivity.

  1. Create the project workspace. Connect source repositories, import GIS extents, and tag project metadata (lead agency, discretionary approvals, timeline). Generate a README for auditors describing AI components in use.
  2. Ingest and normalize documents. Run ingestion flow (OCR, deduplication, section splitting). Store embeddings or structured summaries in your knowledge base with provenance (file name, page, paragraph IDs).
  3. Run resource-area analysis. For each Appendix G topic, execute retrieval-augmented prompts or rules. Capture suggested significance levels, cited evidence, and open questions that need human review.
  4. Draft deliverables with human-in-the-loop. Generate draft narrative text, mitigation tables, and comment matrices. Route outputs to SMEs via collaboration tools with inline source citations and edit tracking.
  5. Log decisions and approvals. Document reviewer changes, final determinations, and sign-offs. Export an audit package (inputs, prompts, outputs, reviewers) for records requests or litigation support.
  6. Publish & monitor. Produce final PDFs/Word templates, push mitigations into monitoring systems, and schedule model/prompt refresh sessions after project closeout.
06 · Quality assurance
