Term	Definition
bioswale	A bioswale is a shallow depression used to capture stormwater runoff and filter out pollutants. They are very similar to rain gardens but are generally used in commercial and municipal settings.
budget advisory group	The members of the budget advisory group are not voting members of the budget committee, but meet jointly with the budget committee, and consist of members of similar organizations and members of the public.
budget committee	The EMSWCD Board of Directors is our budget committee.
budget officer	Budget Officer is an appointed role, for EMSWCD in 08-09 it is the District Manager
ecoroof	A green roof, or ecoroof, is a roof that is designed to be covered with plants. They can be thin and lightweight, or can support several feet of soil and grow plants as large as trees. Green roofs have many benefits over traditional roof coverings. In addition to absorbing stormwater, they also help insulate buildings, cool ambient air temperatures, and provide wildlife habitat. They also last longer than traditional roofs.
EDRR	Early Detection, Rapid Response - A common acronym for invasive species identification and control.

They also last longer than traditional roofs.
green street	Also known as landscaped stormwater curb extensions. Historically Portland has built curb extensions to improve pedestrian safety. A new variation called a stormwater curb extension is landscaped with plants that help filter pollutants from stormwater runoff. They have similar benefits to the conventional curb extension but they also improve water quality, reduce stormwater flow, and enhance the aesthetic look of a neighborhood.
pervious	Unlike conventional paving surfaces that generate stormwater runoff, pervious surfaces allow stormwater to soak into underlying soils. Examples of pervious surfaces include pavers, porous pavement, gravel, grasspave and more.
rain garden	A rain garden is a shallow depression that captures runoff from roofs, driveways, sidewalks and other impervious surfaces around your home. The garden is planted with suitable trees, shrubs, flowers, and other plants allowing runoff to soak into the ground and protect water quality. Rain gardens are a beautiful addition to your landscaping that help protect water quality, maintain natural stream flows, and prevent downstream flooding.
stormwater	Stormwater runoff is considered one of the main sources of water pollution nation-wide. As watersheds become developed, increases in paved surfaces such as parking lots, driveways, and rooftops increase stormwater runoff causing rainwater to run off quickly into storm drains and surface waters carrying the pollutants from those surfaces.
