Preliminary design: The initial phase of design <br />development for transportation projects, <br />where conceptual designs are refined and <br />detailed to a level suitable for environmental <br />review and analysis. <br />Project need statement: A statement <br />identifying the baseline performance need <br />for the project. For each identified project <br />need, there may be one or more performance <br />metrics, targets, and gaps. <br />Project purpose: The primary objective or goal <br />of a transportation project, often established <br />to address specific needs or challenges within <br />a community or region. <br />L <br />Qualitative analysis: Evaluation method <br />that focuses on assessing the quality or <br />characteristics of alternatives based on <br />subjective judgments rather than numerical <br />data. Qualitative analysis may involve <br />assessing factors such as feasibility, social <br />impact, and environmental compatibility. <br />Quantitative data: Numerical data used <br />in the evaluation process to measure the <br />performance of alternatives against predefined <br />criteria. Quantitative data may include metrics <br />such as cost estimates, traffic flow, and <br />environmental impact assessments. <br />I <br />Resiliency: The ability of a transportation <br />system to withstand and recover from <br />disruptions or disasters, such as extreme <br />weather events or accidents. <br />Reversible lanes: Traffic lanes that can be <br />switched in direction to accommodate peak <br />traffic flow, typically operated during specific <br />times or conditions. <br />GLOSSARY <br />Right of way: The land or property owned <br />or controlled by a government agency <br />(e.g. WSDOT, the County, or a municipality) <br />for the construction and maintenance of <br />transportation infrastructure. <br />Roadway widening: Increasing the width or <br />capacity of a roadway by adding additional <br />lanes or shoulders. <br />S <br />Safety: Measures and conditions aimed at <br />protecting travelers and reducing the risk of <br />crashes or injuries within the transportation <br />system. <br />Shoulder: The portion of the roadway <br />adjacent to the travel lanes, used primarily <br />for accommodation of stopped vehicles, <br />emergency use, lateral support of the travel <br />lanes, and where allowed, use by pedestrians <br />and bicycles. <br />Stakeholders: Individuals, groups, or <br />organizations with an interest or concern in <br />the outcome of a project, including residents, <br />businesses, advocacy groups, and government <br />agencies. <br />State Environmental Policy Act (SEPA): State - <br />level environmental legislation modeled after <br />NEPA, requiring assessment of environmental <br />impacts for projects within state jurisdiction <br />and codified in RCW 43.21C. <br />IN <br />Tiered evaluation: An evaluation process <br />divided into tiers or phases, with each tier <br />assessing alternatives based on different levels <br />of detail or criteria. Tier 1 typically involves an <br />initial assessment of all alternatives, while Tier <br />2 focuses on a more detailed evaluation of top - <br />ranked alternatives. <br />VOLUME 1: FEASIBILITY REPORT 1-90 Corridor - Easton to Cle Elum Feasibility Study I xii <br />
