Seattle deploys new system to contain tree roots
It's a common problem in cities: Trees add some green in a concrete jungle, but their roots are tough on sidewalks and streets.
It's a common problem in cities: Trees add some green in a concrete jungle, but their roots are tough on sidewalks and streets.
The city of Seattle is experimenting with a solution. Its Transportation Department is requiring that two red oak trees being planted as part of the Escala development downtown be set inside large blocks to contain their roots and prevent bumps and cracks in nearby pavement.
Marybeth Turner, a spokeswoman for the Seattle Department of Transportation, said it's the first time the city is aware of that such a system has been used in Seattle, but that the city will consider calling for the blocks more frequently.
