Adaptation of stormwater management systems
Due to already-manifesting climate change, components of many existing stormwater management systems are currently undersized, and design standards are now outdated. Systems and standards that are not currently inadequate will likely become so, over the useful life of existing and planned systems. Our studies show that adaptation can be reliable, and designs cognizant of climate change can adequately maintain historical levels of risk.
To adapt communities for more intense storms and population growth, we model historical and projected design storms and population growth, and the resulting peak flows. On a planning-scale, we determine the capacity of existing and planned drainage systems; specify dimensions required to convey peak flows; assess the capacity for peak flow management methods (LIS, SUD, BMP) to mitigate the need for system upgrade; estimate the cost of required adaptation; and provide optimized and risk-based schedules for asset management and capital budgeting.
