Lansdowne Live

Controversy has been brewing in Ottawa over a proposal to turn a brownfield site into a stadium, to be called Lansdowne Live. John E. Martin, an Ottawa businessman, has invited Sherwood Engineers to join a group of politicians, government officials, architects, developers and community leaders to a private breakfast meeting this Thursday, Aug. 27, to discuss the situation. Sherwood will be presenting a case study based on our experience turning a brownfield site into a stadium in San Francisco. We will let keep you updated about the project as the dialogue continues.

Daylighting urban streams has long made sense aesthetically, but now the environmental, traffic calming, and air pollution benefits can be quantified based on new studies of the famous Cheonggyecheon running through downtown Seoul.

From the New York Times:

Cities from San Antonio to Singapore have been resuscitating rivers and turning storm drains into streams. In Los Angeles, residents’ groups and some elected officials are looking anew at buried or concrete-lined creeks as assets instead of inconveniences, inspired partly by Seoul’s example.

By building green corridors around the exposed waters, cities hope to attract affluent and educated workers and residents who appreciate the feel of a natural environment in an urban setting.

Environmentalists point out other benefits. Open watercourses handle flooding rains better than buried sewers do, a big consideration as global warming leads to heavier downpours. The streams also tend to cool areas overheated by sun-baked asphalt and to nourish greenery that lures wildlife as well as pedestrians.

But four years after the stream was uncovered, city officials say, the environmental benefits can now be quantified. Data show that the ecosystem along the Cheonggyecheon (pronounced chung-gye-chun) has been greatly enriched, with the number of fish species increasing to 25 from 4. Bird species have multiplied to 36 from 6, and insect species to 192 from 15.

The recovery project, which removed three miles of elevated highway as well, also substantially cut air pollution from cars along the corridor and reduced air temperatures. Small-particle air pollution along the corridor dropped to 48 micrograms per cubic meter from 74, and summer temperatures are now often five degrees cooler than those of nearby areas, according to data cited by city officials.

And even with the loss of some vehicle lanes, traffic speeds have picked up because of related transportation changes like expanded bus service, restrictions on cars and higher parking fees.

“We’ve basically gone from a car-oriented city to a human-oriented city,” said Lee In-keun, Seoul’s assistant mayor for infrastructure, who has been invited to places as distant as Los Angeles to describe the project to other urban planners.

Speaking at a conference organised by his Foundation for the Built Environment, Prince Charles said slums like Dharavi, featured in SlumDog Millionaire, offer a better model than western architecture for housing booming urban populations, reports the Guardian reports.

Slums, shanti towns, and informal settlements have environmentally and socially sustainable attributes including using local materials, walkable neighbourhoods, and a mix of employment and housing. Prince Charles described this as “an underlying intuitive grammar of design that is totally absent from the faceless slab blocks that are still being built around the world to ‘warehouse’ the poor”.

In a few years we may recognize that these communities have a “built-in resilience and genuinely durable ways of living,” said the Prince.

  • The Bureau of Reclamation allowed flood waters to pass through the Glen Canyon Dam for the third time since the dam was built in 1963, hoping that the 60-hour flood will provide enough water to rehabilitate the Colorado River habitat.

And since a Blue Sky day can still be considered polluted by American standards, there are even more questions as to whether these standards even mean anything.
