There’s no arguing that, at first glance, the Silva Cell just looks like a hunk of black plastic. Its humble and basic form definitely doesn’t reflect the extensive design, testing, and engineering that has gone in to it. Here’s a brief overview of the why the Silva Cell is the way it is.
Back in July, we learned that San Francisco property owners were likely to assume 100% responsibility for street trees (at that time, this was already the case for about 80 percent, of 89,000, trees). Now the transition is officially beginning. What I didn’t realize was that, right around the same time, San Francisco Supervisor Scott… More
Back in March, we introduced our Stormwater Schematics for the first time. Last week’s webinar reminded me that I want to make sure everyone knows about these as they consider how they want to use the Silva Cell on their site. The Stormwater Schematics (look under the Standard Details, Specifications, & Schematics section) are there to help designers… More
We hosted our first live AutoCAD layout webinar last week! For anyone who missed it, we did manage not to mess up the recording (too badly), and it’s now available online.
We don’t talk about engineering as it relates to the Silva Cell much here, mostly because I’m still mastering basic math and have little to bring to the conversation. But that aside, the Silva Cell is a highly engineered product, and since it’s used in urban environments, engineering is an important consideration on all of… More
Back in August 2010, Silva Cells were installed to create a bioretention planter at the Casey Trees headquarters. Now, the good folks at that same organization have added an information panel to explain how the system works.
A few weeks ago I wrote about some of the basics of working responsibly around wildlife. For a major karma power up, though, why not consider doing volunteer work? Arborists, especially experienced climbers, are uniquely valuable as volunteers for groups like the Hungry Owl Project, who need help placing owl boxes and returning fledgling raptors… More
Big news! We’re hosting our first webinar on how to lay out the Silva Cell using AutoCAD next Friday, February 17th at 11am CST.
It’s simple! A collection of some of my favorite New Yorker cartoons featuring trees.
Snowfall seems to have happened very late all across the country this winter, but now that it’s here, most people are trying to find ways to get rid of it. But salt, while effective for deicing roads and streets, can have extremely detrimental effects on trees, causing things such as necrosis, burned tips, or failure… More
