Bioretention Basin at Moses Milch Drive, Howell, NJ
Green Infrastructure uses various techniques to treat and absorb rain water,
also called stormwater, before it reaches our streams, lakes and rivers.
These techniques include bioretention basins, bioswales, filter planter boxes,
rain gardens, green roofs, green walls and porous pavement in urban and suburban
areas. Many of these techniques incorporate native plants and soil mixtures
that keep stormwater from entering our streams and waterways. Stormwater runoff
can carry many different types of pollutants from the surrounding area, such as
fertilizers, pesticides, oil, grease, animal waste and trash. These pollutants
affect the water quality within our streams and can harm the fish and other aquatic animals that live in them.
Bioretention basins, bioswales, rain gardens and filter planter boxes use native plants
and soil mixtures that contain mulch to treat stormwater. These plants have evolved
to withstand local weather conditions in a region. They will absorb the nutrients from
fertilizers and animal waste, utilizing them for their needs. Their roots also create
channels within the soil that allow the water to infiltrate into the ground.
This helps to replenish our groundwater supplies.

Green roofs and walls incorporate plants and soil on buildings. They can be landscaped with
decorative or edible plants and will help filter pollutants absorbed by the rain drops
from the air. Porous pavement allows water to pass through it instead of running off it, which helps recharge our groundwater supplies.
Green infrastructure reduces the volume of stormwater from entering our streams.
By absorbing water into the soil, instead of entering our waterways, it helps to
stop flooding in our streets and homes. This aids in preventing erosion to the stream
banks and causing sedimentation to the stream channel. By maintaining these features,
water can move along a stream’s course and stay within the banks and wetland areas as intended by nature.
Green infrastructure has many other benefits beside the ones mentioned above. It creates
a natural environment that enhances the neighborhood, provides habitat for wildlife and
is less costly to maintain. It also prevents the “heat islandâ�effect observed within cities
which is produced from asphalt and concrete. By cooling the air temperatures and replenishing
water supplies, green infrastructure helps to reduce the impacts of Climate Change.
