Jeremy Barrell, managing director at the Barrell Tree Consultancy, wrote in last week’s Horticulture Week about methods for greening car parks — including the Silva Cell. Car parks (that’s a parking lot, for those of you stateside readers) are some of the toughest areas to integrate green infrastructure because the vast expanse of impervious surface must always… More
While the Silva Cell system can be optimized for tree growth or stormwater management alone, ideally we try to promote both simultaneously. Our standard details lay out the basics, but there are still some questions about just how the Silva Cell functions on sites where it is serving as an integrated tree and stormwater management system….

By Sarah K. Faiks, RLA, LEED-AP Here at DeepRoot we’re very pleased to announce a new partnership with HydroCAD that will allow design professionals to easily model Silva Cells as a part of their overall stormwater management plan.
Vandergrift, PA, a small town in the borough of Westmoreland County about 40 miles east of Pittsburgh, is the subject of a dandy article about a Silva Cell streetscape installation currently underway in the Valley News Dispatch. The Vandergrift commercial district had lacked a stormwater management system, meaning that streets flooded easily even during small rain events…. More
A few weeks ago we tackled Frequently Asked Questions about how the Silva Cell manages stormwater on-site. This week we’ll examine questions about how tree stability is affected by the use of the Silva Cell.1) The proposed trees on my plans will be rooted to a depth of 900 mm of macropore rich soil within the Silva Cells….

In 2008 one of our first on-structure Silva Cell installations was completed in downtown Winnipeg, MB, at the Manitoba Hydro building. (When we say “on-structure” what we are referring to is any installation that takes place on an existing structure, such as a parking garage, rooftop, etc.). GreenSource Magazine just had a great feature about… More
The Mountlake Terrace Community News website has a nice story about the April 5th Silva Cell installation at a local transit center. The site design specified 14 total tree pits consisting of two layers of 16 frames each, or 32 total frames per tree. (That works out to about 320 cubic feet of soil per… More
Our tree and stormwater intallation of over 10,000 Silva Cell frames in downtown Minneapolis, MN(which we call the Marq2) got another great mention this week — this time in Stormwater Magazine’s online newsletter. It’s really gratifying to see this project continue to get recognition. The cost savings to the city are significant, so this is a great… More
When we were first researching and designing the Silva Cell, Tom Smiley, PhD set up a research plot* at the independent Bartlett Tree Laboratory in Charlotte, NC. We were confident about the design principles used in the construction of the Silva Cell, but also wanted to measure exactly how it held up against competitive products… More
We will be participating in the 2010 International Low Impact Development Conference in San Francisco next week. The theme is “Redefining Water In the City,” and as you can imagine, we have a lot to say on that topic! Peter MacDonagh, the Director of Design + Science for Deep Root Urban Solutions, will be there… More
