*'''[[Bioretention|Bioretention cell]]''': A flat-bottomed, depressed planting bed containing filter media soil, a gravel water storage layer and optional sub-drain pipe(s); Also known as a rain garden.

*'''[[Swales: Gallery|Grass Swales]]''': A parabolic or trapezoidal-sized bottom, swale that contains grassed sloping sides and a filter media bottom to both convey overland flow and provide water treatment, and are often subject to more frequent maintenance. They generally contain an outlet structure at the lowest point for water to be sent to another LID BMP or the storm system; sometimes referred to as a roadside ditch. Does not contain check dams.

*'''[[Stormwater planters]]''': A bioretention cell contained within an engineered (e.g., concrete) structure.

*'''[[Swales]]''': Swales are linear landscape features consisting of a drainage channel with gently sloping sides. Underground they may be filled with engineered soil and/or contain a water storage layer of coarse gravel material. Two variations on a basic swale are recommended as low impact development strategies, although using a combination of both designs may increase the benefit.

*'''[[Stormwater planters|Biofilter]]''': Bioretention cell or swale with an impermeable liner or containment structure and sub-drain.

*'''[[Bioswales]]''' are sometimes referred to as 'dry swales', 'vegetated swales', or 'water quality swales'. This type of BMP is form of [[bioretention]] with a long, linear shape (surface area typically >2:1 length:width) and a slope which conveys water and generally contains various water tolerant [[vegetation]]

*'''[[Bioswale]] / [[Dry swale]] or [[Bioswale|Bioretention swale]]''': A gently sloping, linear oriented bioretention practice designed to be capable of conveying water across an elevation gradient. Also known as a bioswale or dry swale.

*'''[[Stormwater Tree Trenches]]''': Linear tree planting structures that feature supported impermeable or permeable pavements that promote healthy tree growth while also helping to manage runoff. Consist of subsurface trenches filled with modular structures and growing medium, or structurally engineered soil medium, supporting the overlying sidewalk.
