"Envision Tomorrow (ET) is an open-access scenario planning package that allows users to analyze how their community's current growth pattern and future decisions impacting growth will impact a range of measures from public health, fiscal resiliency and environmental sustainability.
Envision Tomorrow is a suite of planning tools that includes analysis tools and scenario design tools. The analysis tools allow users to analyze aspects of their current community using commonly accessible GIS data, such as tax assessor parcel data and Census data. The scenario painting tool allows users to "paint” alternative future development scenarios on the landscape, and compare scenario outcomes in real time.
ET provides a quick, sketch-level glimpse of the possible impacts of policies, development decisions and current growth trajectories, and can be used by communities to develop a shared vision of a desirable and attainable future. It can be applied at scales from a single parcel to a metropolitan region.
Scenario comparisons measures include a comprehensive range of indicators relating to land use, housing, demographics, economic growth, development feasibility, fiscal impacts, transportation, environmental factors, and quality of life."
