Overall Steps for Preparing a Transportation Impact Analysis

Step 1: Project Memo

• Inform Public Works: Notify Los Angeles Public Works that a new Transportation Impact Analysis (TIA) is being prepared.
• Project Description: Provide a general description including:
  • Size (square footage per use and/or number of dwelling units)
  • Uses (residential, commercial, etc.)
  • Phased construction details
  • Unusual conditions
  • Building address, Assessor’s parcel number, and project title
• Project Site Plan: Submit a detailed site plan highlighting:
  • Driveway or access locations
  • Loading/unloading areas
  • Parking design and circulation
• Early Consultation: Contact Public Works Land Development Division and Traffic Safety and Mobility Division for requirements on driveway width and internal circulation to avoid last-minute design changes.

Step 2: Other Agency Contacts

• Consultation: Engage with other relevant agencies or adjacent jurisdictions (e.g., Caltrans, neighboring cities, transit agencies) affected by site access and travel demands.
• Address Concerns: Ensure transportation-related concerns of these agencies are addressed in the TIA.
• Written Confirmation: Obtain and provide written confirmation from affected agencies, especially if evaluating intersections in adjacent jurisdictions.

Step 3: Scoping Document

• Preparation: Develop a Scoping Document detailing the assumptions and parameters for the TIA.
• Submission: Submit the Scoping Document through the EPIC-LA portal.
• Incorporate Requirements: Include analysis requirements from other jurisdictions identified in Step 2.

Step 4: Data Collection

• Gather Data: Collect necessary qualitative and quantitative data to support the TIA analyses.
• Traffic Count Data: Ensure traffic count data is collected per the standards and methods in the Transportation Impact Analysis Guidelines.

Step 5: Transportation Impact Analysis Submittal

• Complete TIA: Prepare the completed TIA document.
• Submission: Submit the TIA to Public Works via the EPIC-LA portal.
• Documentation: Ensure all TIA submittals are dated and timestamped.

Step 6: Transportation Impact Analysis Confirmation of Findings Letter

• Review and Approval: Public Works will review and approve the TIA.
• Confirmation Letter: After approval and fee submission, Public Works will issue a TIA Confirmation of Findings Letter summarizing the findings and project requirements.
• Additional Fees: Note that additional fees/deposits may be required for findings and requirements of additional project alternatives if requested by the applicant.

Step 7: Mitigation and Monitoring

• Responsibility: The project applicant may need to report and monitor mitigation measures and corrective actions.
• TDM Measures: Reporting and monitoring of Transportation Demand Management (TDM) measures to improve mobility options at and around the project site may also be required.
• Details in Confirmation Letter: The specifics of these requirements will be outlined in the TIA Confirmation of Findings Letter.

These steps ensure that the Transportation Impact Analysis is comprehensive, addresses all relevant concerns, and adheres to regulatory standards, facilitating smoother project development and implementation
