Relief Line - Draft Evaluation Process and Criteria
The document outlines the evaluation process and criteria for assessing potential options for the Relief Line transit project in Toronto. It describes a four-step evaluation process: 1) identifying potential station areas, 2) assessing station areas against evaluation criteria, 3) developing preliminary corridors connecting the best stations, and 4) evaluating alignments and stations within the preferred corridor. Station areas, corridors, and alignments will be evaluated using criteria focused on choice, experience, social equity, shaping the city, healthy neighborhoods, public health/environment, affordability, and supporting growth. The evaluation process and criteria will be refined based on stakeholder and public feedback.
