New York City is developing techniques like strategically located street plantings, porous pavements, and green roofs to address its problem of excess stormwater into a solution that will improve the health and livability of its neighborhoods, while cleaning up its waterways.
Think not only permeable pavers, but pervious asphalt and pervious concrete, which is fundamentally the same as regular asphalt or concrete, but it does not contain the fine particles that the regular product does. This creates porosity in the matrix, which allows water to flow through and infiltrate into the ground. The volume of stormwater runoff that flows off the pavement is greatly reduced, and the need for curbing, catch basins, and large detention facilities is reduced.
In 2008, David Smith, author of Pervious Interlocking Concrete Pavers for Roadway & Stormwater Facility Reduction, spoke in Tallahassee at an event sponsored by the USGBC. Since that time, the City of Tallahassee and the State of Florida have not overwhelmingly adopted installation of permeable surfaces as a part of construction projects around town.
