Leander - a model of new urban development Reunion Square Leander is fast becoming a model of New Urban Development in Texas. Based on the walkable neighborhood as the basic unit of development, the plan for a new 2,300 acre Leander TOD (Transit Oriented Development) evolves around the future commuter rail station nestled in the Leander Historic Downtown and combines place-making for residents, value creation for land owners, and a quality of life for everyone.
