Do we need a CBD?

From Stuff and Ben Heather about Christchurch:

Christchurch’s central business district is built largely on liquefaction-prone soil, making it “complex and challenging” to construct new quake-resistant buildings.

A geotechnical report commissioned by the Canterbury Earthquakes Royal Commission says the ground beneath Christchurch’s quake-shattered central city sits only one metre to 1.5m above the water table. In addition, it is riddled with underground aquifers and streams.

In the report, Canterbury University associate professor Misko Cubrinovski and Christchurch geotechnical engineer Ian McCahon said the top 25m of soil was a “highly variable” marbling of different layers. Some large buildings sat on firm gravel on one end and silty liquefaction-prone sand on the other.

“These soils are generally considered susceptible to liquefaction, and in some cases (when deposited in a loose state) they exhibit very low resistance to liquefaction.”

I really do wonder why we are pursuing a 19th century concept in the re-build of Christchurch. As my post the other day pointed out we are experiencing a rapid change int eh way we work and where we work. Christchurch has a perfect opportunity to embrace those changes before the rest of the country.
