Q: What are Silva Cells and what's going on at 4th Ave and Virginia Street downtown?

Installation of Silva Cells at 4th and Virginia.

A: The City of Seattle Department of Transportation has taken a new direction in the effort to achieve the central Urban Forestry Management Plan goal to regain lost canopy cover lost to development. Under the direction of SDOT and product distributor DeepRoot, the Escala project at 4th Avenue and Virginia Street in downtown Seattle has undertaken the installation of Silva Cell, an integrated tree, soil and stormwater system designed by internationally renowned Landscape Architect, James Urban.

This first installation in the City of Seattle along the 4th Avenue frontage of this prominent project, required as a condition associated with an SDOT permit to allow tree removal, maximizes the value of limited space in the right of way. The system utilizes the same space to provide soil conditions optimally designed for the growth of street trees while providing full support for standard sidewalk construction. In addition to adding points for any project seeking LEED Green Building certification, the Silva Cell system is currently under evaluation by the Washington State Department of Ecology as a means to meet stormwater management requirements. The future looks "bright green" given applicability to a wide range of private development and public projects in the urban environment where trees and paved surfaces must coexist in a sustainable manner for the long term.

Gold Leaf Awards are given to recognize outstanding Arbor Day events around the country. Cass was presented with the award, along with a crown of golden leaves, during a recent urban forest workshop.

Seattle's Updated Canopy Cover Analysis

The City of Seattle recently undertook a project to estimate canopy levels in 2002/03 and 2007 using more rigorous methods than were used previously. This new study finds Seattle to have about 23% canopy cover. The data from the recent study is exciting because it provides critical information about recent canopy changes across the city as well as within different land uses, neighborhoods, and watersheds. This information will allow the City to better plan and manage Seattle's urban forest.
