Seeing Climate Change as an Engineering Opportunity

 From a recent Atlantic Cites post - link:

"Develop a set of land-use priorities. Infrastructure, including transportation networks, sewage treatment plants, solid waste facilities, energy supply and distribution systems, utilities, and public health facilities demand the highest priorities for adaptation, whether by protection, accommodation (some utility distribution systems could be made submergible; other system elements could be raised or made floatable); or by retreat to higher ground. In any case, for this essential infrastructure, higher flood standards need to be considered (such as the 0.2%/year flood elevations), and margins for sea level rise must be added that are in a time horizon commensurate with the expected lifetime of the facility itself. New rights of way will need to be relocated from low-lying areas to higher elevations.

These measures should be seen as an opportunity. The benefits of rebuilding more resiliently and at safer grounds can catalyze the modernization of what, for many municipalities, has become antiquated infrastructure. Subways, other mass transit systems, and road tunnels should be reconsidered before they become victims to ever more frequent saltwater flooding. Rail systems along the East Coast are a century old in their basic designs, and are located at ever more flood prone elevations and locations. Facing up to the demands imposed by climate change provides us with an opportunity to see a long overdue high-speed train network connecting storm-resilient cities."
