After Going Green, Cities Need Turn Blue

- Adam Clare

Cities need to work with their local ecosystems and not against them. This is evidently true when it comes to waste management and overt displays of green initiatives. There is a harder aspect of ecological thinking for cities and it’s usually beneath our feet: water.

Water systems are complex in every direction – getting drinking water in and storm water out. The way cities plan for water issues is more important than ever before as we enter a time of water scarcity and extreme weather. What we should be doing (and smart cities already are) is designing our urban spaces with the flow of water in mind.

“We need to acknowledge that the water is eventually going to do what the water wants to do, and shift our approach, as human populations living on the Earth, from one of trying to dominate nature to one that acknowledges the power of nature and works in synchrony with that,” says English. “We’ve already set ourselves down this path of dams and levees and water control systems, and it’s really hard to turn back. But we don’t need to keep replicating that. We don’t need to make the situation worse. It’s time to step back from the approach of control and fortification.”

“Cities that today start to embrace water and take advantage of the skills of water, will be the cities that have a better performance economically and socially and politically in 20 to 30 years,” says Koen Olthuis, founder of Waterstudio, a Dutch firm that has found designing around water to be more than a niche market. “When situations change—and that’s happening now, the environment is changing, the climate is changing—cities have to react. You have to change the skills and the performance of the city to give a reaction to this situation, and the reaction should be not fighting it, it should be living with it.”

How the Shape of Cities Impact Public Transportation

- Adam Clare

Cities contain the majority of the worlds population and moving that many people is a challenge, to say the least. Each city has its own design and plan for public transportation and some are clearly better than others. Wendover Productions tackles this question and provides some nice insights into what makes a city a good place for public transit. The video ends with a nice snapshot of the kinds of success that public transit can bring to cities. One example is that Portland has seen an estimated 5 billion dollars in development thanks to their streetcar network.

Waterproofing Cities for Resiliency

The last month brought a lot of rain to the city of Toronto which has led to the Toronto islands being half submerged and a temporary (and lax) travel ban to be put into effect. The rest of the city has fared slightly better. The city has slowly been improving its water management over the years by implementing green roofs and providing more green space along ravines to absorb water. That’s not enough to deal with the increased rainfall from climate change. Over at the CBC they have an article looking at effective ways that Toronto is already using and what more can be done.

Of course, the techniques used in Toronto can be applied to many other cities.

The water that makes it past collection systems or soaks through green spaces ends up in Toronto’s sewer system.

In cases of a heavy downpour, that can send a mix of storm and sanitary water into Lake Ontario, due to the city’s combined sewer system.

While the city has dedicated reserves for storm water, it has no choice but to pump the mixed sewage and storm water into the lake during extreme rainfall.

Stopping Free Parking from Strangling Society

Urban planners spend the last hundred years modifying cities and policies to cater to the car – and that’s been harming us ever since. We’ve looked at how changing parking culture can save America’s economy, cities, increase transportation efficiency, and removing spaces can even make parking easier. Slowly, we are seeing change happening around the world. San Francisco, London, and Buffalo have removed their minimum parking spaces rules. Mexico City is switching their parking laws for new buildings from minimum required parking spaces to a maximum.

Municipal governments are learning that cities are for people and not for cars standing still. It’s time to end free parking and the assumption that the first mode of transportation cities should plan for is cars.

Water companies are not obliged to supply all the water that people would use if it were free, nor are power companies expected to provide all the free electricity that customers might want. But many cities try to provide enough spaces to meet the demand for free parking, even at peak times. Some base their parking minimums on the “Parking Generation Handbook”, a tome produced by the Institute of Transportation Engineers. This reports how many cars are found in the free car parks of synagogues, waterslide parks and so on when they are busiest.

The harm caused begins with the obvious fact that parking takes up a lot of room. A typical space is 12-15 square metres; add the necessary access lanes and the space per car roughly doubles. For comparison, this summer The Economist will move into a building in central London where it is assumed each employee will have ten square metres of space. In cities, such as Kansas City (see map), where land is cheap, and surface parking the norm, central areas resemble asphalt oceans dotted with buildings.

Once you become accustomed to the idea that city streets are only for driving and walking, and not for parking, it is difficult to imagine how it could possibly be otherwise. Mr Kondoh is so perplexed by an account of a British suburb, with its kerbside commons, that he asks for a diagram. Your correspondent tries to draw his own street, with large rectangles for houses, a line representing the kerb and small rectangles showing all the parked cars. The small rectangles take up a surprising amount of room.

Visualizing Bold Climate Action

- Adam Clare

from desmog

There’s so much talk about taking action around climate change that it can be hard to remember what real action looks like. Climate action can take on many different forms and around the world how places react to climate change is different; meaning that we can see so many ways that cities are changing the world. Over at desmog blog they have compiled 11 cities that are making real efforts to take on climate change and what it looks like in picture.

Yokohama, Japan

The city of Yokohama is a winner of the C40 Awards 2016 in the Clean Energy Category. The Yokohama Smart City Project uses Smart Grid technology and solar panels to help cut energy consumption in homes and businesses by between 15 and 22 percent (Yokohama aims to reduce its CO2 emissions by 80 perce
