For those of you who were at GreenBuild a couple of weeks ago, I hope it was a successful show and that you had the opportunity to learn and go to a bunch of the interesting sessions. But if you didn’t go, or just didn’t make it to our session, ASLA’s “The Dirt” blog has… More
By L. Peter MacDonagh, RLA, ISA and Leda Marritz “Without trees, a city is just a scab on the earth.” – Chuck Gilstrap It is hard to imagine any creation as wild or as fanciful as what can be found in nature. One way or another, the natural world is where the shapes and inspiration… More
By Rebecca Stevens I recently read a blog illustrating the Leidenfrost Effect (whereby liquids glide on cushions of vapor) by sticking one’s hand in liquid nitrogen. The pictures are amazing as is the video. You are probably wondering why we are talking about the Leidenfrost Effect on the DeepRoot blog.
I know CEU requirements vary wildly from state to state wildly, but if you need to fulfill some hours — or just like learnin’! — check out a recent DeepRoot-sponsored course available through McGraw-Hill, Greening the Site: Design Options for Sustainability.
It seems I’m a little late to the game on this one, but scientists and programmers from the Smithsonian, the University of Maryland, and Columbia University are collaborating on an iPhone app that will make automatically identifying plant species just from photos of their leaves possible. Then the app would upload the data to a… More
There are no shortage of city and state green initiatives being written and debated out there. With a bit of luck and plenty of hard work we’ve been able to be a part of many of these discussions, bringing in the knowledge of tree, soil, and stormwater experts like L. Peter MacDonagh, RLA, ISA and… More
Got an idea or an opinion on how to make New York City a more sustainable community? Gotham is looking for your ideas and your votes.
I am always on the lookout for design and architecture blogs that cover varied topics in interesting and compelling ways, so I was very happy when I discovered Blooming Rock, a blog focusing on issues around community, architecture and sustainability in the Phoenix area.
Image of flooding at Yesler Street in Seattle by Peter Mooney Yesterday I read an excellent article on Sightline Daily summarizing and analyzing the Washington State Department of Ecology’s latest “draft draft draft” LID Stormwater Standards. This plan outlines WA DOE’s strategy for integrating Low Impact Development (LID) solutions to reduce polluted stormwater runoff that has long… More
Click here for a general overview of the factors that influence how deep tree roots grow. Or, continue reading below to dig in to the science a bit deeper. By James Urban, FASLA Here’s an objection we face a lot when working on Silva Cell projects: “Tree roots don’t grow more than 24″ (65 cm)… More
Earlier this year we wrote about San Francisco’s crowd-sourced tree census project (so neat). And there’s a lot that you can contribute to this project without knowing that much about trees… nonetheless, if you would like to be able to identify more trees more easily (I know I do) then you may want to start… More
A few weeks ago I was in New York, and Al Key and I were out and about checking on root barrier sites that he installed back in 1995. We got to meander around Ditmas Park in Brooklyn (a gorgeous neighborhood that always reminds of how I pictured Stingo’s life in “Sophie’s Choice”) and Tompkins… More
