Optimizing CIP for Enhanced Climate Resiliency in the Watershed

Changes in intensity and frequency of temperature and precipitation provide more extreme parameters that our stressed, and often aging, infrastructure will need to overcome. These changes can mean a dramatic difference in real-time conditions within the watershed that test and potentially exceed the limits of infrastructures’ original design capacity. It is important to understand and […]
