Integrating a Resilience Scorecard and Landscape Performance into a Geodesign Process.

Area of Science:

• Environmental planning
• Geographic Information Science (GIS)
• Climate change adaptation

Background:

• Sea level rise poses significant uncertainties for future spatial planning and design.
• Existing planning tools lack quantitative assessment of design strategies for climate resilience.
• Geodesign offers an integrated approach combining scientific data with planning and design.

Purpose of the Study:

• To develop and apply a Geodesign process for assessing flood vulnerability under sea level rise scenarios.
• To evaluate the effectiveness of proactive planning using newly developed scorecards.
• To quantitatively assess the performance of resilient design strategies using landscape performance measures.

Main Methods:

• Developed a Geodesign process integrating resilience scorecards and landscape performance calculators.
• Utilized sea level rise projections for the year 2100 to define future 100-year floodplains.
• Applied the Geodesign process to create a resilient master plan for League City, Texas.

Main Results:

• The Geodesign process successfully assessed flood vulnerability and guided the development of a resilient master plan.
• Resilience scorecards provided a quantitative method for evaluating proactive planning strategies.
• Landscape performance measures were used to project the future impacts of the implemented master plan.

Conclusions:

• Geodesign, incorporating resilience scorecards and landscape performance measures, is a viable tool for climate change adaptation planning.
• This approach enables quantitative assessment and proactive planning for future spatial conditions impacted by sea level rise.
• The developed methodology can inform resilient urban planning in coastal communities facing sea level rise threats.
