Infiltration Best Management Practices (BMPs) treat urban stormwater runoff as it flows through a filtering medium and into underlying soil, where it may eventually percolate into groundwater. The filtering media is typically coarse-textured and may contain organic material, as in the case of bioinfiltration BMPs. These BMPs are sites ranging from small to relatively large. They are primarily designed for removal of stormwater runoff volume and pollutants in that runoff. They are effective at removing total suspended solids (TSS), particulate phosphorus, metals, bacteria, nitrogen, and most organics. Soluble pollutants such as chloride and nitrate typically through these BMPs and into underlying groundwater.

This category contains photos for stormwater infiltration practices. Additional photos may be found on pages for specific infiltration practices, including the following.

• Permeable pavement
• Tree trench/tree box
• Bioretention - bioinfiltration
• Dry swale (Grass swale)
• High-gradient stormwater step-pool swale
