Occurs when soil or rock fragments are picked up and moved by water, wind, ice, or gravity.
A structure built in a basement or near a house that collects and stores hundreds of thousands of gallons of rainwater from down spouts and nearby impervious surfaces so that it can be used for non-potable uses.
Type of green infrastructure where shallow basin (like rain gardens) or structures collect storm water and use of vegetation and layers of soil and aggregates. Commonly installed in parks, wide road medians and sidewalks.
Constructed structures such as treatment facilities, sewer systems, storm water or storage basins. Often made of concrete
Waterproof layers of synthetic products used to contain water or liquids and prevent draining or infiltration into underlying soil.
Water that moves over or sits on top of the ground such as creeks, streams, rivers, lakes, wetlands and oceans.
An area of land within which water from rain or snowmelt drains into a single body of water, such as a river, lake or ocean.
A type of bioretention. It is a specialized planter installed in the sidewalk area that is designed to manage stormwater runoff from streets and sidewalks.
Practice of collecting and temporarily storing rainwater in rain barrels or cisterns until it can be beneficially used for irrigation or some other non-potable use.
A type of bioretention practice where a collection of trees is planted along an underground infiltration structure. On the surface, it looks just like a series of street tree pits. However, under the sidewalk, there is an engineered system to manage the incoming runoff.
A small structure built across minor channels, swales, bioswales, or drainage ditches; used to reduce erosion and allow pollutants/sediments to settle.
Process of continuously holding or storing stormwater until it evaporates, infiltrates or is used by trees and vegetation.
A roof of a building that is partially or completely covered with growing media and vegetation on top of waterproof membrane. Rainwater is captured and stored in the media until used by plants or it evaporates.
Small, solid fragments of inorganic or organic material that comes from weathering rock or decomposing trees, leaves or vegetation and are carried and deposited by wind, water or ice.
Plant species that have grown naturally in a particular region. Native species tend to be well-adapted to local weather patterns (such as seasonal temperature variations), soil types and precipitation amounts.
