return to green alley

This is where we did our work before making final selections. We have left the work here so you can better understand the framework in which we were learning.

Learning from Other's Thinking

  • Green Streets are covered in Christopher Alexander's - A Pattern Language. He encourages all low volume roads be paved only with stones for the wheel tracks and leave the rest to the earth below. He states "There's too much hot asphalt in the world." The asphalt and concrete destroy the microclimate...they do nothing with the solar energy that falls on them, they are unpleasant to walk on, nowhere to sit, no where for children to play, the natural drainage is devastated; animals and plants are paved away.
  • Green Roofs in Big Cities Bring Relief From Above New York Times, May 23, 2012. 3rd paragraph has great description of problems of co-mingled sewer systems.

  • Chicago Green Alleys Description of the great work being done in Chicago on greening their alleys. The key is the award winning Chicago Green Alley Handbook.
  • Portland's Green Streets - Excellent set of goals and benefits. Also, the 2007 Portland (Maine) Green Streets Tour Map (pdf) gives wonderful examples of what can be done...see the pictures of the Eco-lock pavers. Also, look at the city council resolution it's very good.
  • Green Alleys Filter Water - short CNN story on the benefits of greening the alleys in Chicago. Shows how the alleys are playing a new role in cleaning the water before it gets to the Lake Michigan.
  • Liverpool Alley Report This little project was part of a Masters Thesis by a man named Matthew Cocks in Liverpool. I'm including it because it shows how he worked with a resistant community to make it happen, and it also took very little money. In essence, he worked with the residents to clean up and green the alley with plants. Take a look at the report.
  • Community Greens This project deals with all kinds of shared spaces, including alleyways. Like the project above, this concentrates on adding plant material for beauty. One thing this site mentions, in addition to many others I've read, is that it may be important to put up gates if you are worried about material being trashed or stolen. Just a thought. "The mission of Community Greens is to catalyze the development of shared green spaces inside residential blocks in cities across the United States. We call these green spaces community greens. We believe that the Community Greens approach presents the best opportunity to add usable green space to our cities by converting underutilized backyards and dysfunctional alleys into functional and beautiful shared green spaces that are owned, managed, and enjoyed by the people who live around them."
  • Green Alleys Contribute to Sustainable Cities - One woman from Canada writes about loving alleys and what she feels can be done to make them an important element to sustainable cities.
  • Indonesia's Green Grandma - Video of a woman from one of the poorest neighborhoods in Jakarta teaches her neighbors about recycling, composting and grow plants....and in the process has greened her alley as part of her life-long teaching on the importance of the environment.
  • Story of a Baltimore Alley and much more - here's an alley that was adopted by a women in Baltimore ...the article has a lot resources and examples around the world of greening of alleys activities.

      • Talked to Mike S. at the headquarters in Ontario Canada. he stated the following:
        • Good study of permeable pavers at Senaca College in Ontario.
        • He said that keeping the silt out of the paver aggregate openings is key. Some people sweep the area annually to keep it clean.
        • Digging deep for the aggregate base is key...its the pool that holds the water while it soaks into the natural ground water.
        • key benefit is the reduction of cost in the storm sewer infrastructure.
