Level of Service Assessment for General Plan Consistency for the project in city of Jurupa valley

The Level of Service (LOS) assessment guidelines for the City of Jurupa Valley are comprehensive and focus on maintaining consistency with the City’s General Plan. Here's a summary of the key elements from the provided document:

Level of Service (LOS) Assessment for General Plan Consistency

  • Objective: Ensure all transportation analyses align with the City of Jurupa Valley's General Plan by using LOS as the primary metric.

Methodologies

  1. Intersections:

    • Analysis Tools: Utilize the latest Highway Capacity Manual (HCM) for evaluating both signalized and unsignalized intersections.
    • Data Requirements: Traffic count data (less than two years old), bicycle and pedestrian counts, saturation flow rates, heavy vehicle factors, and grade information.
    • Analysis Tools: Microsimulation should be used where queues build over space and time or where intersections are closely spaced.
    • Mitigation Recommendations: Include exclusive and dual left-turn lanes, protected left-turn phasing, and leading pedestrian intervals.
  2. Roundabout Assessment:

    • Required at intersections with Caltrans facilities or as identified by the Director of Public Works, following current Caltrans standards.
  3. Roadway Segment Assessment:

    • Capacity: Based on criteria in the City’s General Plan.
    • Study Area: Typically within a 5-mile radius unless justified otherwise.

Analysis Scenarios

The analysis should include the following scenarios: a) Existing Conditions: Current traffic data. b) Opening Year Background Conditions Without Project: Includes traffic from approved projects expected to be completed by the project’s opening year. c) Opening Year Background Conditions Plus Project: Adds traffic from the proposed project. d) Opening Year Background Plus Project Plus Cumulative Project Conditions: Adds cumulative traffic from approved and pending projects. e) Cumulative Horizon Year No Project Conditions: Forecasts based on long-term growth. f) Cumulative Horizon Year Plus Project Conditions: Adds project traffic to the cumulative horizon forecast.

Phased Projects

  • The assessment can be done by phase, project trigger points, or overall, with additional studies required for each phase.

Data Collection, Project Trip Generation, and Forecasting Methodologies

  1. Traffic Counts:

    • Counts must be recent, collected on specific days, and under non-holiday, non-vacation periods. Counts should include turning movements, bicycle, pedestrian counts, and classifications.
  2. Trip Generation:

    • Based on the ITE Trip Generation Manual, with adjustments or local data collection as needed.
    • Truck trip generation for high truck-generating uses should be calculated on a case-by-case basis.
    • Internal trip capture for mixed-use developments should use recognized methodologies.
  3. Trip Distribution:

    • Should be based on origin-destination patterns, using mobile data or traffic models like RIVTAM/RIVCOM.
  4. Trip Forecasts:

    • Cumulative conditions should be developed using RIVTAM/RIVCOM.

Intersection and Roadway Segment Operating Requirements

  1. Signalized Intersection:

    • Maintain LOS D; improvements needed if project traffic causes degradation to LOS E or F.
  2. Unsignalized Intersection:

    • Improvements required if the addition of project traffic degrades the LOS from D to E or F or adds 5.0 seconds or more of delay.
  3. Roadway Segment:

    • Similar requirements as intersections, with improvements required if project traffic causes degradation to LOS E or F.

Site Access, Safety, and Other Analyses

  • Intersection Sight Distance, Driveway Length, and Gated Entrance: Adequate sight distance and appropriate driveway lengths are required.
  • Limiting Driveway Impacts: Driveways should not impede traffic and must be strategically placed.
  • Pedestrian, Bicycle, and Transit Access: Must ensure adequate facilities and access points.

Traffic Signal Warrant Analysis

  • Required for all unsignalized study intersections and must follow the California MUTCD guidelines.

Improvements for Transportation Impacts

  • Level of Service Improvements: Focus on mitigating project-level impacts and cumulative deficiencies, with fair share contributions calculated for necessary improvements.

This summary encapsulates the key points, ensuring that all necessary guidelines for maintaining LOS consistency with the City of Jurupa Valley’s General Plan are followed during project assessments.
