This document outlines the methodology for the Land Use Targets, a product designed to disaggregate jurisdictional population, housing, and employment targets to smaller geographic areas like Census Tracts and FAZs. The methodology details the step-wise approach for creating an alternative future land use dataset, incorporating major assumptions regarding development capacity and policy objectives consistent with the VISION 2040 regional growth strategy. It serves as a starting point for analyses requiring future population and employment distributions.

This document, presented to the ST3 Expert Review Panel, details ridership forecasting for the Sound Transit 3 (ST3) initiative. It outlines changes to forecasting inputs, including demographics and auto operating costs, and presents sensitivity tests on factors such as highway tolling, congestion, parking prices, and demographic shifts. The report also addresses Downtown Tunnel Capacity and provides projections for daily transit trips up to 2040, using 2014 as the base year for analysis.

This document presents the Draft ST3 Financial Plan, which details the sources and uses of $54 billion over the period of 2017 to 2041. It outlines the allocation of funds, including $36 billion for capital improvements, and demonstrates adherence to financial policies and planning assumptions. A comprehensive risk assessment, employing both static stress tests and dynamic Monte Carlo simulations, is included to ensure the plan's affordability and financial robustness for regional transit expansion.

This document outlines the Transit-Oriented Development (TOD) strategy as an integral component of the Sound Transit ST3 System Plan. It details Sound Transit's mandate to implement a regional equitable TOD strategy, emphasizing the creation of diverse, mixed-use, and mixed-income communities with a strong focus on prioritizing affordable housing. The strategy integrates TOD considerations into system planning, project development, and the disposition of surplus property, supported by stakeholder engagement, optimized station layouts, and dedicated funding for TOD planning and affordable housing initiatives.

This document presents a draft list of projects identified for inclusion in the Sound Transit 3 (ST3) system plan, following extensive public input and detailed project studies. The plan outlines proposed expansions across Light Rail Transit, Bus Rapid Transit & Bus services, and Sounder Commuter Rail projects. Additionally, it details High Capacity Transit (HCT) studies, policies, and programs aimed at enhancing regional mobility by improving connectivity, increasing ridership, and fostering efficient transit solutions.
