Here is the statement from Metro:
Metro today announced that release of the draft environmental impact report/environmental impact statement (EIR/EIS) for the State Route 710 North Study will be delayed. Metro is working with Caltrans on a revised schedule and will make an announcement as soon as it is confirmed.
Metro had hoped to release the draft environmental documents this spring but the work was delayed while the latest Southern California Association of Governments (SCAG) regional travel demand computer model for analyzing the alternatives was calibrated and applied.
Metro was one of the first agencies to use the new 2012 model in a major project. Calibration and validation of the model was not completed until last year and the associated travel demand forecasting for all of the alternatives was not completed until February of this year. However, it has become apparent that additional time is required to complete the technical studies, which means that the release of the Draft EIR/EIS must be delayed in order to perserve the integrity of the environmental process.
Metro has been working with the community, technical consultants and Caltrans on various alternatives for addressing traffic and environmental impacts within east/northeast Los Angeles, the western San Gabriel Valley and the region generated by a 4 ½ mile gap in the original 710 Freeway design that exists between Alhambra and Pasadena.
The draft EIR/EIS will thoroughly analyze five alternatives – Bus Rapid Transit, Light Rail Transit, Transportation System Management/Transportation Demand Management, a freeway tunnel, and a No Build option.
Metro, Caltrans, local cities and private developers all are required to use the SCAG regional travel demand model as a basis for project planning. It predicts future (2035) traffic through a thorough analysis of projected travel patterns considering such factors as population and employment growth, goods movement, land use changes and other variables. Other critical analysis including air quality, a health risk assessment, noise and energy effects also depend on travel demand computer modeling.
Metro and Caltrans are fully committed to ensure that the public has a voice in the process. Detailed analysis for each alternative will be incorporated in the SR 710 North Study draft EIR/EIS.
