Visions of Sixth Street - plans for a new, pedestrian-friendly bridge in Los Angeles

Visions of Sixth Street - plans for a new, pedestrian-friendly bridge in Los Angeles | Greener World | Scoop.it

Three finalists present plans for major new bridge in Los Angeles:

The groups—headed by HNTB, AECOM, and Parsons Brinckerhoff— have all been shortlisted to create the city’s new Sixth Street Viaduct. Their vivid public presentations were the first glimpse of what will likely be LA’s next major icon.

The original 3,500-foot-long structure, a famous rounded Art Deco span designed in 1932, has been deemed unsalvageable due to irreversible decay, and in April the city’s Bureau of Engineering called for a competition to design a new, $400 million, cable stayed structure.

Following the city’s lead, all three teams presented plans that not only showcased memorable forms, but embraced people-friendly designs, including pedestrian paths, parks, and connections to the river below. The push reveals Los Angeles’s focus on attracting people and talent through increased livability. Such moves are a welcome, if uphill battle considering that so much of the city has been designed for cars, not people...

Climate-Proofing Urban Areas with Floating Housing

Climate-Proofing Urban Areas with Floating Housing | Greener World | Scoop.it

The wave of floods that hit Britain in April focused attention, once again, on the vulnerability of homes in low-lying areas...

But what if a house could simply rise and fall with the waters? That’s the vision of Baca Architects, designers of the UK’s first ‘amphibious house’, which has just received planning permission for a site near Marlow, in Buckinghamshire, on the banks of the Thames.

The lightweight, timber-framed structure sits on a floating concrete base that is built within a fixed ‘wet dock’ foundation. In the event of a flood, the concrete base rises up as the dock fills with water, ensuring the house floats safely above the waves. The base effectively acts as a free-floating pontoon, and should have a lifetime of around 100 years before needing renewal or replacement.

Climate proofing’ urban areas is a growing area of focus for architects and planners. Amphibious architecture looks set to join rain gardens, green roofs and permeable paving in the array of techniques available...

Creative concept. I wonder how they plan to ensure grounding / earthing the electrical system.
