Green infrastructure uses vegetation, soils, and natural processes to manage water and create healthier urban environments. Green infrastructure refers to the patchwork of natural areas that provides habitat, flood protection, cleaner air, and cleaner water. At the scale of a neighborhood or site, green infrastructure refers to stormwater management systems that mimic nature by soaking up and storing water. - United States Environmental Protection Agency Infiltration Based Green Infrastructure Techniques • Bioretention Cells (Rain Gardens) • Planter Boxes • Vegetated Swales and Bioswales • Street Trees and Tree Box Filters • Infiltration Galleries or Swales • Permeable Pavement Bioretention Cells and Rain Gardens Bioretention Cells or Rain Gardens?

To increase infiltration and pollutant removal, bioswales are designed with an underlying soil media and an underdrain. However, there are little data on the ability of these stormwater control measures (SCMs) to reduce pollutant concentrations. A bioswale treating road runoff was monitored, with volume-proportional, composite stormwater runoff samples taken for the inlet, overflow, and underdrain outflow. Samples were tested for total suspended solids (TSS), total volatile suspended solids (VSS), enterococcus, E. coli, and turbidity. Underdrain flow was significantly cleaner than untreated road runoff for all monitored pollutants.

  • Green Streets Brochure
    Green Streets Environmentally Friendly Landscapes for Healthy Watersheds Green Streets in Your Neighborhood Department of Environmental Protection Franklin Knolls & Clifton Park Green Streets in Your Neighborhood page 1 of 10 Introduction What are Green Streets? Green Streets are roadway Low Impact Development (LID) designs that reduce and fi lter rainfall and pollutants that wash off surface areas (storm- water runoff), and enter our streams, degrading the water quality of our local streams and rivers. Green Streets is a County initiative that captures stormwater runoff in small landscaped areas that let water soak into the ground while plants and soils fi lter pollutants. Green Streets practices help to replenish groundwater and basefl ows in our streams, rather than sending polluted, heated water through pipes directly into our streams. They also create aesthetically attractive streetscapes, provide natural habitat, and help visually to connect neighborhoods, schools, parks, and business dis- tricts. Green Streets practices are constructed within the street right-of-way. Fac- tors like utilities, existing drainage patterns, soils, tree impacts, the amount of runoff volume, and many other considerations are taken into account in the design of Green Streets. Stormwater 101 As our neighborhoods were developed, the watersheds that support local streams were greatly altered. Buildings, roads, driveways and lawns have replaced much of the natural vegetation, forest cover, and soils that used to slowly fi lter rainwater. Development provides us with places to live, work, and play, but its hard surfaces prevent rainwater from soaking back into the ground and allow pollutants to enter local streams more easily. Rainwater falling on hard surfaces is directed to a storm drain where underground pipes transport it to local streams, along with pollutants it picks up along the way.
