This post is now out of date! Please see the updated post here. In the day-to-day, we can become so focused on what isn’t working with the way we design and plant street trees that it can be difficult to focus on the people and places that are actually doing right by them. It’s just so… More
Earlier this year, Silva Cells were installed at the new Martin Luther King, Jr. memorial in Washington D.C. This site will commemorate the legacy of Dr. King but is not solely about the past; it is also about the future.
I read a lot of news stories about development projects described by words like sustainable, walkable, dense, and multi-use. These characteristics are experiencing a real surge in emphasis from both a design standpoint and from media coverage, and rightly so. They are some of the pillars of community design that support the physical and economic… More
Readers on the West Coast may already be aware of this, but Stanford University has one of the oddest mascot’s in collegiate sports: a tree.
To kick off 2012, we’re reprinting this great post written by Matthew Gordy for the Boston Society of Landscape Architects back in April 2011. One thing I love about this post is the theme of high performance. We plan and expect for high performance with other types of utilities and urban infrastructure because we want… More
As the year winds down, we’ll be looking back at some of the project case studies we’ve completed in 2011. This case study — written in British English, for those of you in North America — discusses a trees and stormwater Silva Cell project in a Derby car park. You can find the original case… More
Community-based tree care organizations are a critical component of tree longevity in many cities and towns. These organizations provide training for volunteers to become advocates and stewards of trees in their neighborhoods. At Tree Pittsburgh, a non-profit in Pittsburgh, PA, this program is called Tree Tenders. Last week I talked to Tree Tender Nicole Moga…. More
I get a lot of calls about using the our Geomembranes (aka water barrier, aka bamboo barrier) as a substitute for the Tree Root Guides. In these tough economic times, it makes sense that everyone is trying to find ways to save a few dollars here and there. However, the geomembrane does not have the same… More
Community-based tree care organizations are a critical component of tree longevity in many cities and towns. These organizations provide training for volunteers to become advocates and stewards of trees in their neighborhoods. At Tree Pittsburgh, a non-profit in Pittsburgh, PA, this program is called Tree Tenders. There are nearly 1,000 Tree Tenders volunteers in the… More
Most urban trees in North America are planted in inadequate soil volumes and other inhospitable conditions that doom them to premature decline and death, meaning that we rarely capture their full ecological utility or enjoy their beauty. But, there are exceptions to every rule, and street trees are no different. Indeed, some trees planted in urban areas… More
As the year winds down, we’ll be looking back at some of the project case studies we’ve completed in 2011. This one examines the new headquarters of Casey Trees, a renowned non-profit dedicated to the restoration, enhancement, and protection of urban trees, where Silva Cells are helping to manage stormwater on-site in one of the first… More
As an urban trees and soils consultant, I am always looking for studies that examine how trees survive and adapt to the built environment. One of the biggest questions and confusions I encounter is the issue of whether organic matter (something that I discussed in a previous post) needs to be added to urban… More
