Incorporating Nature into Houston-Area Flood Mitigation H-GAC Flood - PowerPoint PPT Presentation

Incorporating Nature into Houston-Area Flood Mitigation H-GAC Flood Management Committee July 15, 2020 Amanda Fuller Director, Texas Coast and Water Program National Wildlife Federation

Objectives • Trends • “Natural infrastructure” – an umbrella term • Community benefits • Equity • Case studies • Next steps

Trends Growing interest in alternatives to conventional approaches Conventional “gray” infrastructure • Costly • Aging • Increasingly unreliable Healthy natural systems • Cost-effective • Adaptive to disturbances • Provide numerous co-benefits

Trends Texas General Land Office State Action Plan for CDBG-MIT

Trends FEMA’s Building Resilient Infrastructure and Communities (BRIC) Program

What is “natural infrastructure?” Natural systems that provide essential services and benefits to society • Clean air and water • Food • Natural resources • Fish and wildlife habitat • Recreational opportunities • Protection against natural hazards (i.e., “natural defenses”)

Performance of Natural Infrastructure • Globally, the estimated value of ecosystem services provided by natural systems, as a whole, ranges from $125–$145 trillion per year.2 In the United States alone, coastal habitats provide estimated benefits valued at over $100 billion annually. • Natural and nature-based approaches for hazard mitigation can be equally or more effective than conventional structural approaches, and they are often more cost-effective. • An acre of wetlands can typically store 1-1.5 million gallons of floodwaters. • In the Gulf region, every dollar spent on wetland restoration can yield more than seven dollars in flood reduction benefits. • According to the Greater Houston Area Flood Mitigation Consortium, where watersheds remain undeveloped acquisition of land along the bayous and creeks is a cost-effective flood mitigation tool.

What is “natural infrastructure?”

Community Benefits of Natural Infrastructure • Air quality improvements • Reduction in extreme heat • Enhanced water quality • Climate resilience • Cultural and spiritual fulfillment • Recreational opportunities • Greater quality of life • Environmental stewardship

Centering Equity Red areas represent the maximum observed flooding during Hurricane Harvey. Each shaded section of the map represents a census tract, colored according to its relative vulnerability. Darker areas are more vulnerable.
