Bioretention definition

Bioretention means the water quality and water quantity stormwater management practice using the chemical, biological and physical properties of plants, microbes and soils for the removal of pollution from stormwater runoff.
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.
Bioretention means a LID BMP that reduces storm water 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 the NPDES Permit as biofiltration.

Examples of Bioretention in a sentence

  • Bioretention – A stormwater retention area that utilizes woody and herbaceous plants and soils to remove pollutants before infiltration occurs.

  • Bioretention facilities include, but are not limited to, rain or rainwater gardens, bioretention planters, or linear cells or swales.

  • Bioretention basins, or rain gardens, may be used only when approved by Berlin Township.

  • Bioretention cells or swales can be incorporated into these landscaping strips.

  • Before the establishment of common benchmarks, nearly every speech recognition system claimed “99% accuracy.” Of course, that number could mean very different things depending on the test set, the training set, the com- plexity of the task (e.g., vocabulary size), etc.


More Definitions of Bioretention

Bioretention means the water quality and water quantity stormwater management practice using the chemical, biological and physical properties of plants, microbes and soils for the removal of pollution from stormwater runoff. A bioretention facility is an engineered facility that stores and treats stormwater and may be made up of multiple components, such as vegetation, layered soils (native and/or engineered), and underdrain storage.
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 an 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.
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 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 process to manage stormwater runoff, using the chemical, biological and/or physical properties found in a natural, terrestrial-based community of plants, microbes and soils.
