The Push to Revitalize Urban Alleys Across the United States Is Fostering Community and Sustainability – CityLab

lead_large

 

For places that were meant to be unseen, alleys take up a not-insubstantial amount of space. A 2011 report by Mary Fialko and Jennifer Hampton, graduate students at the University of Washington*, found that in Seattle, there are 217,000 square feet of public alley space downtown, 85 percent of which are underused. The report estimated that reinvigorating alleyways could increase the number of total public space in the city by 50 percent.Alleys, too, are vital players in a city’s overall ecosystem. As the need for cities to rely on more sustainable approaches has become more pressing, the proliferation of trash and flooding in alleyways has come to be seen not only an aesthetic blight, but an environmental one.And as Daniel Freedman of the Los Angeles Sustainability Collaborative says, there’s a lot of crossover between sound environmental practices and livability. Revitalizing an alleyway creates an opportunity to introduce green infrastructure, but also, Freedman says, it invites the surrounding community to collaborate on improvements and make use of the space.

A Small City with a Big Vision: Chattanooga’s New Form-Based Code – Form-Based Codes Institute : Form-Based Codes Institute

Chattanooga’s form-based code is part of an innovative vision for the city’s economic, environmental and cultural future. Following a recent visit to Chattanooga, Bruce Katz wrote in a Brookings Institute blog, “Something special is happening in Chattanooga.” As Katz points out, too often venture capitalists “pay too little attention to small and mid-sized cities with …

Jetson Green – Net Zero Prefab That Can be Built in Just Three Days

Unity Homes has recently unveiled a prefab home, which is sustainable yet still made to last for at least as long as traditionally constructed homes. The home has a number of certifications, including LEED v4 Platinum, while it is also net-zero energy and can be constructed on site in three days or less. It is also fitted with the largest number of Cradle to Cradle (C2C) certified building products used in a residential project to…

Introducing ‘treeconomics’: how street trees can save our cities | Cities | The Guardian

In Toronto, researchers recently found that people living on tree-lined streets reported health benefits equivalent to being seven years younger or receiving a $10,000 salary rise. As well as studies revealing benefits from everything from improved mental health to reduced asthma, US scientists have even identified a correlation between an increase in tree-canopy cover and fewer low-weight births. And economic studies show what any estate agent swears by: leafy streets sell houses. Street trees in Portland, Oregon, yielded an increase in house prices of $1.35bn, potentially increasing annual property tax revenues by $15.3m.

Coastal property values could erode if nourishment subsidies end — ScienceDaily

The value of many oceanfront properties on the East Coast could drop dramatically if Congress were to suddenly end federal beach nourishment subsidies. Values could fall by as much as 17 percent in towns with high property values and almost 34 percent in towns with low property values. A gradual reduction of the subsidies, in contrast, is more likely to smooth the transition to more climate-resilient coastal communities.

Sprawl costs US more than a trillion dollars a year | Better! Cities & Towns Online

Sprawl costs the American economy more than $1 trillion annually, according to a new study by the New Climate Economy. That’s more than $3,000 for every man, woman, and child.

These costs include greater spending on infrastructure, public service delivery and transportation. The study finds that Americans living in sprawled communities directly bear $625 billion in extra costs. In addition, all residents and businesses, regardless of where they are located, bear an extra $400 billion in external costs.

FDR v. Obama

“I should like to have it said of my first Administration that in it the forces of selfishness and of lust for power met their match. I should like to have it said of my second Administration that in it these forces met their master.” – FDR

“Yes we can.” – Obama – But we didn’t.

Urban Life and a Microscopic Attention | Sustainable Cities Collective

Small-scale urban spaces can be rich in biodiversity, contribute important ecological benefits for human mental and physical health (McPhearson et al., 2013), and overall help to create more livable cities. Micro_urban spaces are the sandwich spaces between buildings, rooftops, walls, curbs, sidewalk cracks, and other small-scale urban spaces that exist in the fissures between linear infrastructure (e.g. roads, bridges, tunnels, rail lines) and our three dimensional gridded cities.

Maps and Measurments of the Expansion of Cities | Sustainable Cities Collective

 

We are living in the midst of the urban century. Though it is common knowledge that the world is urbanizing, it can be striking to visualize this growth on a map. This animation from Unicef maps countries’ urban populations from 1950 to 2050, and shows that urbanization is a global phenomenon set to continue for decades:

Pentagon Plans for Climate Wars

Now that the Pentagon wants to address climate change, progress may be possible.

After all we only implemented food assistance when the head of the Selective Service in WWII warned Congress that too many draftees were being rejected due to malnutrition, the interstate highway system is actually the  Dwight D. Eisenhower National System of Interstate and Defense Highways, and the internet and numerous other technologies were funded by DARPA (Defense Advanced Research Projects Agency).

No fear, no funds.
