How to Prevent Storm Runoff and Protect Waterways

How to Prevent Storm Runoff and Protect Waterways

Rain gardens, bioswales, permeable pavements—to mimic nature, reduce stormwater runoff, and filter pollutants for sustainable water management

Implementing Green Infrastructure

1

Curb stormwater pollution. With native plants, they filter rain, reducing runoff and promoting local waterway health

Bioretention Cells

Use gravel-filled trenches to store stormwater, gradually infiltrating into soil. Optionally, an underdrain system can be integrated                                     >>>

Infiltration Trenches

Continuous or block pavers—pavement layer over gravel. Porous surface allows stormwater entry, storage, gradual infiltration. An underdrain system is optional                       >>>

Porous Pavement

Rain Barrels: Efficiently collect roof runoff, release at a controlled pace or for irrigation. (Cisterns also fall under “rain barrel” category.)                                      >>>

Rain Barrels

Designed as vegetated channels or depressions. Provide a natural means for allowing a portion of intercepted stormwater to gradually infiltrate the underlying soil

Vegetative Swales

Measures like stabilizing slopes and using erosion control blankets help manage stormwater runoff efficiently, reducing pollutants in waterways.
