Stormwater runoff refers to rainwater or melted snow that flows over the ground and does not get absorbed into the soil. Instead, it collects in streams, rivers, or drains and carries along any pollutants or debris it encounters along the way, which can cause water pollution and flooding.

Actions to reduce
stormwater runoff in ways that allow water to infiltrate and move more slowly through the ground can also ease flooding and peak flows that otherwise threaten salmon redds.
Green infrastructure promotes the natural movement of water by collecting and
managing stormwater runoff from streets, sidewalks, parking lots and rooftops and directing it to engineered systems that typically feature soils, stones, and vegetation.
«Difficult at best» Adaptation can include efforts to reduce
stormwater runoff by expanding pervious surfaces, building defensive walls to protect critical sites, strengthening building standards, and expanding «green infrastructure» that can retain floodwater.
In New York City, Green Infrastructure describes an array of practices that use or mimic natural systems to manage
urban stormwater runoff.
Green infrastructure is being used as a tool to
mitigate stormwater runoff by restoring natural ground cover which allows precipitation to infiltrate into the soil.

filtering stormwater runoff for $ 35 million less than conventional technical methods.
Rain gardens are vegetated or landscaped depressions designed with an engineered soil layer that promotes infiltration of
stormwater runoff into the underlying soil.

limit stormwater runoff to the «maximum extent practicable.»
The resulting
stormwater runoff carries dirt, oil and other pollutants to rivers and streams and can also cause erosion and flooding that harm properties and wildlife habitat.

found stormwater runoff to be one of the top 10 causes of compromised environments in rivers, streams, lakes, ponds, reservoirs, bays, and estuaries.
Rain gardens — also known as bioretention cells — are depressions in the landscape that
trap stormwater runoff so microbial activity, filtration / adsorption, and plant uptake can remove pollutants.
For example, the study found that in order to maximize water quality in the Dominguez Channel watershed, which spans 133 square miles in southern Los Angeles County, the city would need to install 65,000 bioretention basins — landscaped depressions or shallow basins used to slow and treat on -
site stormwater runoff through physical, chemical and biological processes.

stormwater runoff ponds (230 and 780 milligrams chloride per liter).
From coast to coast, America's waters are suffering from numerous pollution insults
like stormwater runoff and agricultural waste.
Unless communities adapt, intense precipitation will cause
greater stormwater runoff, agricultural runoff, and sewer system overflows that threaten water quality and public health.
In 2010, the City launched the Green Infrastructure Plan, an alternative approach to reducing CSOs and improving water quality that combines traditional infrastructure upgrades with cost effective green infrastructure installations that capture and
retain stormwater runoff before it ever enters the sewer system.
Oregon's Museum of Science and Industry re-designed its parking lots to
minimize stormwater runoff and maximize local infiltration of rainwater.
Nor is there enough public finance available to maintain the existing «gray infrastructure» — like dams,
stormwater runoff systems, and treatment plants.
Using the old maxim that «the problem is the solution,» this design
captures stormwater runoff — usually a cause of soil erosion — and turns it into an abundant resource for times of scarcity.
Like providing appropriate housing for indigenous people living on the city centre fringe, providing sustainable infrastructure support for the burgeoning urban sprawl, reinvigorating discussion on urban renewal by population density consolidation, managing the
extensive stormwater runoff that pollutes the beaches and waterways, while wasting precious rainwater.
In undisturbed landscapes, such as woods and open field, there is very
little stormwater runoff because rainwater filters through soil or evaporates into the atmosphere.
