Stormwater Runoff
Controlling stormwater runoff and preventing erosion...
from residential properties, agricultural areas and construction sites keeps pollutants out of rivers, streams and bays and protects wildlife habitat and drinking water supplies.
"Green Infrastructure" refers to newly developed or recently improved methods of managing stormwater runoff that are cost-effective, sustainable and environmentally beneficial. These include large-scale projects such as restoring, maintaining and protecting natural landscapes. Smaller projects include green roofs, rain gardens, swales, permeable paving and rainwater harvesting.
Ashland, VA's municipal parking lot serves as a multifunctional space for residents and visitors. It's paved with permeable pavers.
The parking lot of the EPA's Edison, NJ, Environmental Center is made of permeable pavers.
The City of Hugo, MN, is a local leader in stormwater reuse. The City has facilitated 10 projects in which stormwater is stored and reused for irrigation on public and private land.
Flood-prone New Orleans, LA, provides ample information about Green Infrastructure options and community organizations that can help with education and installation on their website.
Portland, OR's Environmental Services has created a helpful brochure and video about the construction of rain gardens.
Resources
The EPA's National Pollutant Discharge Elimination System is a comprehensive website offering detailed information and data on hundreds of subjects regarding wastewater, stormwater and erosion.
A detailed report from the New York Department of Environmental Conservation on stormwater management can be found on their website. Buried deep inside their Design Manual, Chapter Nine (pages 9-37) is an excellent report on permeable paving with guidance for siting, installation and cost.
NOAA Digital Coast's website features an interactive Green Infrastructure Mapping Guide for resilience to coastal hazards.
