The Silva Cell is a subsurface integrated tree and stormwater system that holds unlimited amounts of soil while supporting traffic loads beneath paving and hardscapes. The healthy soil housed within the Silva Cell serves two important functions: growing large trees and treating stormwater onsite. The integration of green utilities like soil, trees and water into urban areas substantially improves their design sustainability and helps alleviate some of the most pressing ecological challenges – including air and water quality, rising temperatures, flooding and erosion from daily rainfall events.
