The porous alley in Boston, Massachusetts demonstrates one way the Blue Cities approach will create more resilient cities. The project was constructed using porous asphalt with a large storage and recharge chamber underneath the pavement surface.
Planning and design were completed in 2013 and the project was constructed in 2014. Monitoring of the project is ongoing. To date, monitoring shows the project has been successful at recharging significant volumes of water, as well as reducing pollution and stormwater flows into area sewers.
The porous alley is located along Alley 543 between West Canton and Holyoke Streetsin the South End of Boston. The area is a historic neighborhood, consisting primarily of Victorian row houses and apartment buildings. The alley includes a ten foot right of way owned by the City, and adjacent private land which is used primarily for parking.
