Need a lively discussion topic for the dinner table, a road trip, or a hot date? How about stormwater credits for trees?! A group of us started discussing the intricacies of how to set up a stormwater credit system for trees two summers ago, only to discover that the subject was even more “interesting” (both… More
Toronto has one of the most ambitious urban forestry plans in North America. In addition to setting minimum soil volumes for street trees of 30 cubic meters (1,059 cubic feet) per tree, they have set a goal of increasing their overall tree canopy from 17 percent to 40 percent. In 2007, the Bloor-Yorkville Business Improvement… More
We spend a lot of time at DeepRoot talking about the big picture of “green infrastructure,” but in order to assist in creating viable and sustainable urban eco-systems, we must actually produce products. Plastic products.
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
Disturbance to pipes and sidewalks caused by roots is one of the most commonly cited complaints about trees. One of the many questions I get asked about is whether they penetrate and plug up drain pipes frequently. The answer – perhaps surprisingly – is no.
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.
Soil. Stormwater. Sustainable Infrastructure.
