This document discusses enabling high performance transit-oriented development (TOD). It summarizes that TOD requires high quality public transportation, appropriate urban form and density around transit stations, integrated transport services and pricing, and street networks designed for walking and biking. Case studies from Portland, Charlotte, and Washington D.C. show how TOD can reduce traffic, emissions, and parking needs when supported by policies around land use, pricing, and coordination across agencies. The document provides an inventory of opportunities for TOD in D.C. and recommends actions like education, prioritizing investment, and station area planning to implement TOD.
