A time of difficult decisions is upon us, as much as we all might wish differently. Forests are aflame, rivers increasingly wash away lives, and familiar weather patterns are no longer. The people of Boulder face increasingly difficult tradeoffs in the face of accelerating climate disruptions. As a city, our public safety mandate requires that effectively protecting lives is our top priority. Boulder has a significant decision before us regarding the CU South property which would enable us to better guard against destruction and death from flooding. This subject is never far from our public safety conversations, as Boulder has the highest flood risk of any Colorado city by a very wide margin. As recent fatal floods in Fort Collins, China and Germany have shown, these events are increasing in frequency, magnitude, and resulting human suffering. We must respond to growing climate threats through emissions reductions and adaptation measures that improve our resilience. The planned South Boulder Creek flood mitigation project is precisely this latter response, and our upcoming choices will determine whether and when lives will be protected.
