Bridge seismic risk needs hard look

After the success of the recent counter-petition process, I hope there is now time to do a proper analysis of the seismic liabilities of the Johnson Street Bridge compared to the cost of a seismic upgrade. According to The Law of Canadian Municipal Corporations (Rogers 1971), the standard of care for municipal roads is dependent on the economic means of the municipality and the requirements of the public.

It also seems prudent to include a study of other city-owned earthquake liabilities such as City Hall and Crystal Pool to determine if the bridge deserves priority by this factor alone.

If it's determined that a seismic upgrade is not required due to liability issues alone, the referendum should include the option of forgoing it entirely. The option between a replacement and a seismic upgrade of the current bridge seems to weigh heavily in favour of replacement.

The main question for me then is not whether to replace the bridge, but whether a seismic upgrade is economically prudent. If it is, let's replace the Blue Bridge. If it isn't, refurbishment might be the way to go.

Old-growth logging blamed for Island wasteland

A patch of the Tahsish River Valley on western Vancouver Island is the new poster child for the ecological impact of old-growth logging — this time on limestone karst, perhaps the world’s most fragile landscape.
