Cities of the Future Act as Sponges

When it rains cities should hold all the water. In the 20th century that idea would have been laughed out of the room; today, we know better. Urban water management is vital to a healthy city, ecosystem, and flood mediation. The old idea of building giant channels of concrete to force water out of their natural areas (the best example of this is in L.A.) is thankfully being replaced with better ideas.

One of those better water management ideas is to just soak it all up. Make the city a sponge.

It tries to do it in three areas. The first is at the source, where just like a sponge with many holes, a city tries to contain water with many ponds.

The second is through the flow, where instead of trying to channel water away quickly in straight lines, meandering rivers with vegetation or wetlands slow water down – just like in the creek that saved his life.

This has the added benefit of creating green spaces, parks and animal habitats, and purifying the surface run-off with plants removing polluting toxins and nutrients.

The third is the sink, where the water empties out to a river, lake or sea. Prof Yu advocates relinquishing this land and avoiding construction in low-lying areas. “You cannot fight the water, you have to let it go,” he says.

Make Believe Ideas and the City

The mayor of Toronto, like other 20th century mayors, believes in mystical solutions to urban problems. In the 21st century smart mayors are shedding the myths and make-believe thinking around urban design. In forward looking places we see neighbourhoods made livable and large swaths of land made into the human scale. Paris is opening more areas for people and even New York reclaiming useless land. What am I referring to? Cars. The magic ability of cars to solve all problems. Over at Spacing they have quite the piece on this make-believe notion we should abandon.

In the make-believe world, the car is a necessity, which allows many planners and politicians to resist changes that adversely affect “traffic” on roads. Thirty percent of Toronto households nonetheless manage to get around without owning a car, even while their transit journeys are routinely blocked by cars. A measurement of traffic volume by all modes along the Bloor corridor in October 2019 showed 267,000 daily trips, among which there were only 17,000 cars. Politicians nonetheless claimed that a proposed bike lane in the same stretch would prevent people from going downtown.

To Revive Main Streets Let’s Make them People Focussed Instead of Business Focussed

Since the proliferation of big box stores and malls small cities have been struggling to keep their downtowns engaging and profitable for businesses. What if we rethought our downtowns to be about people and making a community instead of profit centres? That’s the very question a small city in the UK asked and found the answer was to make the city for people. They converted old stores to community spaces and sure enough more people kept showing up. Now their city is vibrant and businesses want to be there to capture all the foot traffic. If you put people first then the rest will follow.

The Stockton vision is to buy up, repurpose, restore and reconfigure the heart of the town, emphasising events, independent enterprise, green space and conviviality. As a glamorous statement of intent, in just over a fortnight one of the finest art deco theatres in Britain will reopen its doors. The Globe, a Grade II listed building, has stood derelict on the high street for a quarter of a century, rotting from within. Built in 1935, in its heyday it hosted the Beatles, Little Richard and Stevie Wonder. On 6 September, McFly will play the first gig of a new era, at the biggest venue of its kind between Newcastle and Leeds.

The cost of the lavish and exquisite restoration – funded by council borrowing and a lottery grant – soared close to £30m and has generated political pushback. But according to Claire Frawley, the council’s town centre development officer, it will provide jobs, a revitalised sense of place and a footfall of up to 200,000 visitors a year, acting as a regenerative hub for the new Stockton.

“People are desperate to get involved,” says Frawley, “they’re desperate to come and work here. There will be public tours soon, and the local demand is huge. This place is part of the town’s heritage and you can feel the pride.”

A Real Smart City Lacks Smart Technology

A few years ago Silicon Valley mega corps thought all cities should be made “smart” by tracking all citizen data. There was a concentrated effort by Google to violate privacy rights in Toronto and bullying the city into a finance deal which only benefit the advertising giant. Torontonians protested and the company backed out.

In Columbus, they ran a well funded research project into the smart city only to discover that the “smart” aspects showed mediocre results. We already have solutions to most problems cities face like mass transit and better funded health services. It’s time to fund the boring, old, not “smart” solutions in our cities.

Now it’s clear that private firms can’t predict the future of cities and may not have their best interests in mind. Davis says Columbus’ selection led to a flood of proposals from companies that ultimately proved difficult to manage, and “at times distracting.” Meanwhile, Uber (and Lyft) have pulled out of autonomous vehicles, notably after an Uber testing vehicle struck and killed a pedestrian in Arizona. Google sibling Sidewalk Labs promised in 2017 to construct a sensored-up neighborhood of the future in Toronto. But it killed the project last year amid the pandemic and a bitter political battle with privacy advocates and local groups and developers.

How Cities Deal with More Intense Heat Waves

Global warming is bringing more intense heat waves to our urban environments which means cities will need to adapt to the new temperatures. Indeed, regular readers will recognize a lot of ways cities can mitigate extreme heat from painting roads white to regulating green roofs. Over at Arch Daily they have compiled a neat list of good ways cities are exploring to stay cool.

In an attempt to combat the urban heat island effect that affected Sydney’s suburbs, the city has made light-coloured roofs mandatory for all new houses. At the same time, the authorities require residential lots to feature at least one mature tree, as the canopy cover in some neighbourhoods is only 1 per cent. The new regulations will initially be applied in the suburb of WiltonSydney’s current climate strategy intends to further address urban heat by growing the city’s canopy cover by 50% by 2030 and implement cool pavements.
