Silva Cells were originally developed to provide adequate tree rooting volumes even in areas dominated by pavement. They do this by extending rootable soil volume under HS20 load bearing surfaces. These rootable tree volumes and the large trees that root in them are also an efficient sustainable stormwater management system. Sometimes people ask us if… More
Today’s blog entry is reprinted testimony from Dr. Franco Montalto, PE, given to the New York State Assembly Standing Committee on Environmental Conservation at a public hearing on the environmental causes and effects of extreme weather events. The testimony was given on January 13th, 2013 and originally appeared on SwimmableNYC’s blog. Dr. Montalto is an… More
There are many advantages to using permeable pavers over Silva Cell installations. The two biggest are maximizing stormwater volume, rate, and quality benefits, and minimizing installation and maintenance labor requirements. In today’s post, I’ll be discussing these two stormwater benefits (as well as a few extras!) in more detail.
Here is this week’s “Ask Jim Urban” column. Jim Urban, FASLA is an expert on urban trees and soils and his recent book, Up By Roots, is the industry bible on these topics. Jim was also involved in the development and design of the Silva Cell system. In this column, which we’ve run for once a… More

Most designers are probably already familiar with the practice of using aggregate or gravel as a form of underground stormwater storage. For those who aren’t designers, the principle is simple: aggregate (gravel) is full of small voids – macropores – that can fill with water, acting as on-site stormwater storage. The aggregate is strong enough… More
