It's not a bad plan, attributed to Ludo Campbell-Reid who introduced us to streets where cars could be slowed by subtle means, cobble stones for example, so pedestrians could easily share the road. That has worked rather well, I think, in Federal St and Fort St.
Now the roads crossing Queen St are to be blocked and the whole CBD divided into traffic "cells" permitting no driving through the city. I think it could work quite well, giving enough car access for most people and getting rid of the kerbside parking that blights High St in particular. But whether the plan works for Queen St will depend on whether the planners start watching what people do.
Architects work this way, I'm fairly sure. When they take on a site they watch what people do there, where on the site people like to be, where they sit, where they look, where the sun, slope, light and views make it most natural and comfortable to be. If there are no people already using the area, I imagine the architect takes her children there at the weekend and watches where on the site they go and what they do there.
Auckland planners appear to have done this too for the Viaduct Basin and done it even better for the Wynyard Quarter waterfront. But never for Queen St. I'm old enough to remember when they closed Lower Queen St to create the now late, unlamented Queen Elizabeth Square. It was nicely designed, and redesigned from time to time when it didn't attract much use.
But one day somebody at the council - it was certainly not the planners - let food carts move into the square. First one or two, then more. They positioned themselves where they chose and pretty soon the place was alive. People were sitting on all the seats the planners had artfully designed, and on the munching interesting selections of exotic fast food.
It couldn't last. After a couple of years the council decided the square had become a "mess" and something had to be done about. First they ordered all the food carts into a straight line, eventually they banished them in yet another redesign. There was a pretty fountain there for a while, and a kinetic artwork that didn't attract much interest. None of that really worked.
I don't know what might work for Queen St. The Herald has moved out of the valley and even though the new building is just over the ridge on the slopes of Freemans Bay, I'm surprised how seldom I go back there. But they have been squeezing cars out of Queen St for a long time and there must be some uses people are making of those widened footpaths and street furniture.
If not, the planners should close the street and see what happens. Don't design too much, just wait and watch what people do.
