This is a copy of many of the photographs we've gathered for the site, particularly those illustrating structural BMPs or specific features. Note some photographs are from external sources, references listed in descriptions. If you can't find what you're after, try checking other people's LID photograph databases. If you're seeking photographs of plant species, we've mostly linked content directly from the Wikimedia Commons.


BioretentionA shallow excavated surface depression containing prepared filter media, mulch, and planted with selected vegetation. cells

BioswalesLinear bioretention cell designed to convey, treat and attenuate stormwater runoff. The engineered filter media soil mixture and vegetation slows the runoff water to allow sedimentation, filtration through the root zone, evapotranspiration, and infiltration into the underlying native soil.

Dry ponds

Extended tree pits

Filter Strips

Grass SwalesA shallow constructed channel, often grass-lined, which is used as an alternative to curb and channel, or as a pretreatment to other measures. Swales are generally characterized by a broad top width to depth ratio and gentle grades.

Infiltration chambers

Infiltration trenches

Permeable Pavement

Soil cells

Stormwater planters


Check damsStructures constructed of a non-erosive material, such as suitably sized aggregate, wood, gabions, riprap, or concrete; used to slow runoff water. Can be employed in practices such as bioswales and enhanced grass swales.
