Silva Cells and On-Structure Installations The DeepRoot Silva Cell system has been installed in dozens of rooftop and on-structure projects around the world. Whether on top of existing structures — such as parking garages — or a garden terrace atop a new construction project, Silva Cells can help create structure as well as bioretention for… More
Introduction When we talk about low-impact development and design today, the term “suspended pavement” is frequently used — but rarely defined. It’s important to understand this practice within the field of green infrastructure, so let’s examine what suspended pavement is as well as its history, uses, composition, and case studies. What is Suspended Pavement? Suspended… More
DeepRoot’s Silva Cell has been installed in dozens of rooftop projects around the world. Whether it is on top of existing structures such as parking garages, or a garden terrace atop a new construction project, Silva Cells can help create structure, bio-retention for tree roots wherever installed. There are two types of green roof installations,… More
– Silva Cells solved the 2009 CSO stormwater transition during the Marquette and 2nd Avenue (MARQ2) busway project, mitigating stormwater runoff. – Over 167 trees were installed along 48 blocks of downtown Minneapolis each with 588 ft3 (16.6 m3) of soil volume. – Above ground, the trees provide shade, clean air, and beauty. Below ground,… More
A 240-year-old market glows with resilient green infrastructure and people-centric design Richmond, Virginia’s 17th Street Farmers Market is the oldest of its kind in the nation, declared a public market in 1779. (Though some accounts claim it started unofficially as early as 1737). As commerce grew, so did the market, and in 1854 a building… More
I often get asked, “Do you have any Silva Cell installations in New York City?” After more than a decade of Silva Cell presence in the Greater NYC area, I am a bit incredulous that it is not more well-known in the industry. The answer is a definitive “yes!” A review of our projects in… More
This blog is the first in a series of three that focuses on maintenance for Green Infrastructure (GI) systems and includes design considerations for selecting and designing GI systems, developing O&M manuals, and training maintenance staff to maintain the installed GI facilities. Conventional or grey stormwater infrastructure systems require maintenance in order to provide the… More
When there are existing trees on a development site, moving the tree is often considered as a method of tree preservation. Often the tree is growing in an “inconvenient” location for the project and tree preservation is either desirable, politically expedient, or required by local ordinance. While trees can be moved, there are some realities… More
This article is the final one in a series about tree-friendly development. In past articles we discussed tree-friendly design and building practices. Today, we discuss the vital role of a consulting arborist in the tree preservation process. All arborists are not the same “Arborist” is a generic term for a tree specialist. “Certified Arborist” means… More
Good design preserves existing trees during a development project. However, the most tree-sensitive design will not be enough if tree-friendly building practices are not in place. Many times a tree that was damaged during development may not show symptoms of decline for a few years, so the cause and effect is often not obvious, unless… More
