Colombo Street

Hi, I'd like to refer to the posting of Catherine Slingerland on the main group page regarding the transformation of Colombo St.

I quote:
"I've recently become very excited about the Jan Gehl Public Space Public Life Study for Christchurch Central City. You can find the
entire 159 pages of the study on the Christchurch City Council website.
In the section on recommendations, Colombo Street has been identified
as the main traffic corridor," to be calmed and turned into a street
for pedestrians, bicycles and public transport." Although St.Albans is
not considered to be in the Christchurch central business district, it
does have the northern end of Colombo Street. Christoph Hensch would
like to see the intersection of Colombo and Edgeware Road turned into a
single surface square with a tree and seating in the middle of what is
now the street, as exists in many European centres. Great idea, but we
can start thinking about transforming the rest of Colombo Street south
to Bealey Avenue into a traffic corridor. The on-street curb parking
has got to go! So how can we meet that goal? The residents could be
approached, off-street car parking assessed, garages and sheds
de-cluttered, carports built, etc. This could be a great community
project. What do you say?"

What would it need to achieve some significant improvement of the innercity, in a way that is not just Council driven?
