The volume and distribution of precipitation is expected to change across the Chesapeake Bay watershed in the coming years as a result of climate change. These changing hydrologic conditions, especially when coupled with ongoing development, pose a risk to stormwater infrastructure and public safety. To date, state and local governments have use a series of precipitation volume-based engineering design criteria to manage risks to public health and safety as well as the performance of their stormwater BMPs. However, many stakeholders fear those criteria may not be well suited to address future climate conditions.  

To help maintain the resilience of stormwater practices to climate change, CSN has developed a series of reports synthesizing the most recent climate projections for the Chesapeake Bay watershed, and the implications for stormwater design. Read the reports below:
