Last week we attended a Silva Cell green roof installation at the Medical Mart and Convention Center in Cleveland, OH. This project was designed by URS Corp. and Gustafson Guthrie Nichol, and installed by Independence Excavating.
Man. The day is finally here. The Silva Cell installation guidelines are now available on our YouTube channel.
In February, the U.S. Forest Service published a report indicating that cities around the country are losing around 4 million trees per year. Of the 20 cities included in the study, 17 showed significant losses of canopy cover, and 16 showed significant increases in impervious hardscape (or paved surfaces that don’t absorb water). At the same time,… More
This post is by Bill Spiewak, an arborist in Santa Barbara, CA, and originally appeared on his blog, Treemendous. Last month in my arboriculture class, I may have implied to my students that this instructor is falling off the deep end. I asked them to stand and assume the yoga position, tree pose. My objective… More
Phytoremediation is the use of green plants and their associated microorganisms to stabilize or reduce inorganic and organic contamination in soils and surfacewater or groundwater. In other words, the process of using trees and other plants as biological filters. It is also a key component of what we mean when we talk about ecosystem services… More
Many designers understand the need for the Silva Cell and support it as an effective design tool for tree growth and stormwater management in urban environments. Yet, all too often it gets value engineered out of projects for being too pricey. While cheaper than creating a custom suspended pavement system, and actually money-saving in the long-term,… More
Trees are effortlessly artful. This artfulness may be part of why they have such a calming and restorative effect on people and can elicit such powerful emotional attachment. Trees are also functional infrastructure. You can debate which role is more valuable, but from an economic standpoint, infrastructure usually wins hands-down. That’s one reason why recent… More
There are so many reasons why trees are beneficial in urban areas. This abundance of evidence can have the strange effect of sometimes making the benefits we cite feel like platitudes rather than proven, compelling facts (“trees are so great, here’s a million reasons why…” *staring off in to space*). For that reason, as much… More
New York has an ambitious Green Infrastructure plan, and lately their enhanced bioswales have gotten additional attention. These five foot by twenty foot planters look great from street level, so why do I feel uneasy about them?
For a long time, root barriers have been the bread and butter of DeepRoot’s business. We take our name from what they’re designed to achieve, and if they’re used correctly, they are an effective way to eliminate pavement and sidewalk heaving by tree roots. But can they hurt trees?
Fossils are pretty amazing. These ghostly remains contain incredible detail about the ancient living things that accidentally created them. A recent article in the Wall Street Journal about the discovery of 385 million year old forest fossils got me wanting to know more about some of the most eerie, lovely specimens.
Silva Cells were recently installed at the University of South Carolina as part of a larger multi-use tailgate facility. The site, which is across the street from the school’s stadium, formerly housed the South Carolina State Farmers Market.
Soil. Stormwater. Sustainable Infrastructure.
