Bioretention means a LID BMP that reduces stormwater runoff by intercepting rainfall on vegetative canopy, and through evapotranspiration and infiltration. The bioretention system typically includes a minimum two-foot top layer of a specified soil and compost mixture underlain by a gravel-filled temporary storage pit dug into the in-situ soil. A bioretention BMP may be designed with an overflow drain, but may not include an underdrain. When a bioretention BMP is designed or constructed with an underdrain it is regulated by the municipal NPDES permit as biofiltration.

Bioretention means engineered facilities that store and treat stormwater by passing it through a specified soil profile, and either retain or detain the treated stormwater for flow attenuation. Refer to the current City of Lacey Stormwater Design Manual for bioretention design standards.

Examples of Bioretention in a sentence

• A Rain Garden (Bioretention Area) is an excavated depression area on the surface of the land in which native vegetation is planted to filter and use stormwater runoff.

• Bioretention improves water quality, with the vegetation planted in the facility filtering the water, and the root systems encouraging or promoting infiltration.

• Bioretention areas, also known as (infiltration) rain gardens typically provide rainwater capture of impervious drainage areas (roof, parking and patio areas) and provide pre-treatment of runoff storm water by allowing the runoff water to enter an infiltration system prior to entering the storm system, percolating back into the ground, or evaporating.

• Bioretention (F-5) A shallow depression that treats stormwater as it flows through a soil matrix, and is returned to the storm drain system.

More Definitions of Bioretention

Bioretention means an integrated stormwater management practice that uses the chemical, biological, and physical property of plants, microbes, and soils to remove or retain pollutants from stormwater runoff. Bioretention facilities are depressions that can be isolated detention cells, swales for conveyance as well as treatment, or a connected-cell hybrid of the two. Bioretention facilities include compost amended soils, landscape plantings selected for tolerance to a range of conditions and a mulch layer.

Bioretention means a LID BMP that reduces stormwater runoff by intercepting rainfall on vegetative canopy, and through evapotranspiration and infiltration. The bioretention system typically includes a minimum 2-foot top layer of a specified soil and compost mixture underlain by a gravel-filled temporary storage pit dug into the in-situ soil. As defined in this Ordinance, a bioretention BMP may be designed with an overflow drain, but may not include an underdrain. When a bioretention BMP is designed or constructed with an underdrain it is regulated by Order No. R4-2012-0175 as biofiltration (Order No. R4-2012-0175).

Bioretention means a water quality practice that utilizes vegetation and soils to treat urban stormwater runoff by collecting it in shallow depressions, before filtering through an engineered bioretention planting soil media.

Bioretention means a storm water infiltration device consisting of an excavated area that is backfilled with an engineered soil, covered with a mulch layer and planted with a diversity of woody or herbaceous vegetation.

Bioretention means an engineered facility that stores and treats stormwater by passing it through a specified soil profile, and either retains or detains the treated stormwater for flow attenuation.

Bioretention means a BMP that consists of a bed filled with soil, gravel, or other material and planted with suitable non-invasive (preferably native) vegetation. Stormwater runoff entering a bioretention system is filtered through the planting bed before being either conveyed downstream by an underdrain system or infiltrated into the existing subsoil below the planting bed.

Bioretention filter" means a bioretention basin with the addition of a sand filter collector pipe system beneath the planting bed.
