Building codes for flood- prone area typically require elevating thee lowest loour too or above thee Base Food Elevation (BFE). However, if precipitation extremes increase, thee BFE itself may by too low. Many coasure communities are now adopting freeboard requirements - elevating structures an additional one tso three feet above thee BFE - to acquict for unknown changes in loud levels.

Stormwater Management andGreen Infrastructure

Traditional stormwater systems - pipes, detention basins, and channels - are often sized using historical rainfall data. When precipitation trends bring more intense storms, these systems precire undersized and cause localized locazized looding. Coastal foudplain regulations are now pushing to ward stormwater standards that require for 24-hour storms with return period of 100 years or more.
