Achieving Urban Resilience: Washington DC

Actively managing sun and rain to improve District health and livability and slow global warming while saving billions of dollars
This report provides an in-depth analysis of the costs and benefits of cool and green roofs, solar PV, cool and porous pavements, bioretention and expanded tree cover and combinations of these solutions at scale across Washington, DC (the District). Table E1 below summarizes the report’s main findings about the cost-effectiveness of these surfacing solutions. The District could reap net benefits of at least 5 billion dollars over 40 years by widely adopting cool roofs, green roofs, solar PV, bioretention, rainwater harvesting, reflective pavements, permeable pavements, and urban trees. Benefits valued include energy cost savings, improved air quality and public health, reduced stormwater runoff, climate change mitigation, and increased resilience and employment.
