We have a lot of resources about implementing minimum soil volumes for urban trees on this blog. Recently we’ve updated our list of municipalities that have a minimum soil volume standard. Trees need an adequate volume of root, oxygen-rich soil to thrive, and minimum soil volume policies are a powerful tool for arborists and other advocates… More
As the northern hemisphere begins the thaw and our record-setting snow melts, we are drawn to the transformation of the landscape. Our love of trees runs deep, and we are all looking forward to digging in the soil. In Minnesota, the technical team is also trying not to get too excited – sometimes it snows… More
Over 20 years ago, the City of Del Mar along the southern California coastline began a citywide process to improve streetscapes with the intention to preserve and enhance the tangible qualities of the community. In 2019, construction began of the downtown streetscape portion, which will bring these concepts to fruition, building up the commercial center of… More
Nearly eight years ago, we installed a large Silva Cell system along 48 blocks of downtown Minneapolis. Called Marquette and 2nd (MARQ2), this green stormwater infrastructure project is in an ultra-urban, mixed-use area that needed to accommodate mass transit, cars, and pedestrians. The designers (SEH and URS) specified Silva Cells for stormwater management in addition… More
This post is the third in a series of three sharing findings from research conducted on 10 Silva Cell projects across North America. Read part one about study design here and part two about our initial findings here. We’ve already shared some of the initial findings from this study in earlier posts. Today, we’ll discuss… More
This post is the second in a series of three sharing findings from research conducted on 10 Silva Cell projects across North America. Read part one, where we discuss the study design, data collection, and raw growth results, here. After designing the study and selecting the Silva Cell projects, we had to decide what performance… More
In order to document the growth and performance of trees in Silva Cells, and to validate our own approach to designing for both trees alone and trees-and-stormwater in combination, in 2015 we undertook a research and monitoring study of 10 Silva Cell projects across North America. This was a big project, as you might imagine…. More
Today marks the eighth and final episode of season 1 of Remarkable Objects (sob). Since this podcast is all about the intersection of nature and the urban environment, I wanted to use this last episode to talk about engaging ordinary citizens to create a better urban forest. As much as policies and regulations shape our… More
I’ve been a fan of Kaid Benfield’s writing for years, so I was incredibly excited when he agreed to be interviewed on Remarkable Objects. I was first introduced to his work as a reader of “Switchboard,” the blog of the Natural Resources Defense Council. His posts stood out to me because of their conversational tone,… More
Soil is not something I spent a lot of time thinking about before starting to work for DeepRoot. But in that time, I’ve come to see and appreciate soil as an almost-magical substance. Soil is foundational to so many things: the biological processes of billions of organisms, carbon sequestration, plant life, and the built environment… More
