− | File:Bioretention No Infiltration.png |thumb|600px|Bioretention cell schematic capturing runoff from an adjacent parking lot. Design for this LID BMP can vary, but generally all facilities include a gravel storage layer, an optional choker layer, media layer, mulch and vegetation. This specific variation does not infiltrate water into the surrounding native soil, potentially due to the site possessing soils prone to subsidence, or the site may be considered to be a pollution hot spot. There are two other types of bioretention variations, [[Bioretention: Full infiltration|full infiltration]] and [[Bioretention: Partial infiltration|partial infiltration]], which can be explored with their own image maps.
