2 Overview Drivers of change What is geodesign? Why is geodesign important? Who is doing it? How can you get started?

7 What is Geodesign? Geodesign is a iterative design method that uses: - stakeholder input - geospatial modeling - impact simulations - and real-time feedback To facilitate: - holistic designs - and wise decisions representation process evaluation change impact decision Source: A Framework for Geodesign, Carl Steinitz 2012

8 Geodesign is the process for informed design & wise decision making GIS Design Act Evaluation The science of geography + Purposeful design + Evaluation + Decision + Implementation Understanding Precedes Action

9 Doing Geodesign (with CityEngine) Cross sector evidence and performance-based design Good pleasant loose weight shade public health air pollutants heat safe unsafe planted median bike lanes cleaner air and water on street parking Bad walkability Good

11 representation Specifying the Method The how questions process evaluation change impact decision Primarily concerned with establishing the methodology of the study What do the decision makers need to know to make a decision? What are the areas of conflict? Who should comprise the geodesign team? What is the change strategy? What criteria will be used What data and in what format and at what scale?

12 Change Strategy - Offensive vs. Defensive Project are either: - Offensive new development must occur in areas suitable for development (opportunities) - Defensive historic buildings, riparian zones, and viewsheds must be preserved (constraints) - Or a little of both A good example that might arise, especially using GIS, where one action feeds into another might be: - Restoring a river flow (defensive), reduces parking which is countered by restoring street car (offensive)

13 Evaluation and Assessment Vulnerability Erosion Hazard Suitability Viewsheds Flash flood hazard Accessibility Fire Hazard Proximity to utilities

14 Change Strategy Anticipatory vs. Exploratory Anticipatory - You have a clear design concept in mind - And then you work towards it Exploratory - You don t know what the best course of action is - So you need to try a lot of different things

15 Change Strategy Combinatorial and Rule-based Constants Requirements and their options Historic sites Mountain views Improve accessibility Connect trails and bikeways Decrease flood impact Move buildings Improve economy Zoning change Flood zones - Local Streetcar service Build dam New development Future Flood zones - Reg Increase parking Restore green infrastructure Fire hazard Evaluation models
