Also known as the SAFE Foundation System, developed by architect and inventor Greg Henderson and his team at , is a way to build in flood zones and coastal areas. It is designed to float buildings, roadways, and utilities in a few feet of water. The self-adjusting floating environment draws from existing technologies used to float concrete bridges and runways such as Washington's SR 520 and Japan's Mega-Float. It also absorbs the shock of earthquakes, allowing buildings and their related communities to remain stable. Arx Pax is working with Republic of Kiribati and Pacific Rising to solve for sustainable development challenges associated with rising sea levels.
