  34. Alternatives evaluation framework

  35. Alternatives development process System Alternatives Development Plan ST3 Representative project Alternatives Level 1 Level 2 Level 3 Preferred Draft Environmental evaluation screening screening screening Impact Statement (EIS) Alternative framework (segments) (segments) (corridorwide) Refine Define end-to- ST Board identifies Identify broad Develop remaining end alternatives Preferred range of initial evaluation alternatives and and evaluate Alternative and alternatives and criteria and evaluate with with more other alternatives screen with detailed methods quantitative for environmental simple criteria measures review measures Public involvement Preferred Present Level 1 Early scoping Present Level 2 Alternative findings input findings discussions and EIS scoping

  36. Screening process Broad range of initial alternatives Refine remaining alternatives Further evaluation Preferred Alternative 36

  37. Evaluation criteria, measures and methods Purpose Evaluation Evaluation Evaluation and Criteria Measures Methods Need

  38. Evaluation criteria, measures and methods Level 1 is more qualitative ; Levels 2 and 3 are more quantitative . For example: Evaluation Quantitative/ Measure Methods Criteria Qualitative Environmental Natural and built Level 1 Qualitative Impacts to known natural and built resources Effects environment Historic properties Quantitative Number of adjacent historic property impacts Parks and recreational Quantitative Number of adjacent parks and recreational resource impacts resources Water resources Quantitative Estimated square feet of in-water impacts Hazardous materials Quantitative Number of adjacent listed hazardous material site impacts Visual Quantitative Proximity to residential areas or protected views Level 2 Environmental Noise and vibration Quantitative Number of potentially affected sensitive receivers Effects Property acquisitions and Number of potentially affected properties, including potential residential and Quantitative displacements business displacements Burden on historically Assessment of how potential acquisitions/displacements would affect historically Qualitative underserved populations underserved populations relative to other communities Assessment of temporary construction impacts to community, including potential Construction impacts Qualitative for transportation, noise, vibration, and visual effects that could disrupt community Level 3 Environmental Same measures and methods as Level 2, but for more defined and refined corridorwide alternatives Effects

  39. Purpose and Need Provide high quality rapid, reliable and efficient peak and off-peak light rail transit service to communities in the West Seattle and Ballard corridors Level 1 criteria and measure Reliable service • Potential service disruptions and recoverability Travel times • Estimated light rail travel times 39

  40. Purpose and Need Improve regional mobility by increasing connectivity and capacity through downtown Seattle to meet projected transit demand Level 1 criteria and measure Regional Connectivity Projected Transit Demand • Ridership potential • Network integration and operational flexibility to meet future demand Transit Capacity • Passenger carrying capacity in downtown 40

  41. Purpose and Need Connect regional growth centers as described in adopted regional and local land use, transportation and economic development plans and Sound Transit’s Long -Range Plan Level 1 criteria and measure Regional growth centers served • Station proximity to PSRC growth centers Sound Transit Long-Range Plan consistency • Accommodates future light rail extensions 41
