Just read Chris Grygiel of Seattlepi.com blog post about the new tree measure in Seattle that could grant developers exemption for retaining trees if the trees preclude or prohibit the development of the site. This new tree protection measure seems a ham-fisted attempt at protecting trees which are in current developments (houses, offices, etc) not future developments. I can understand the need for exemption, as cities like Seattle try to encourage development in the city to create denser (in-fill) developments on existing sites instead of allowing urban sprawl to continue unabated. However, exemptions should be given only where the tree is inspected and assessed by a qualified arborist that the tree is at the end of its life or of very poor form for it species. Developers should be encouraged wherever possible to retain all existing mature trees (including tree offsets/buffers) to maintain the green canopy of the city. The benefits of trees within a city are indisputable and the length of time it takes for new trees to mature on a development is decades.
Developers may find this stance very anti-development – however new development should occur within cities to provide denser housing, offices, and retail. This is where more flexibility in tree protection measures are needed. Flexibility would come in the form of clauses that grant exemptions if the developer can show that they are going to plant new trees or install a green roof that contributes the equivalent benefit as the tree to be removed. For a developer to provide the information for this type of exemption may increase the cost of developments as the developer will have to engage consultants to assess the green value of the new trees and green roof. However, the increased environmental cost of trees being removed may be far greater in the long term.

Calgary Herald reports
CALGARY – The newly released design for the city’s new pedestrian bridge has been derided by some Calgarians as a gaudy red waste of $24.5 million, and praised by others as a sleek, elegant contribution to downtown Calgary.
But to the architect, Santiago Calatrava, the Bow span is the most accessible, functional and technically challenging one he’s ever made…
