Why is stormwater regulated on construction sites?

Stormwater runoff from construction sites is regulated for a few key reasons:

  1. Sediment Control – Exposed soils and land clearing activities on construction sites can lead to high rates of erosion and sediment accumulation into nearby waterbodies during rain events. This sediment can harm aquatic life habitats.
  2. Pollution Prevention – Construction materials, chemicals, demolition debris and other items can contaminate stormwater flowing off-site. Polluted runoff harms surface water quality.
  3. Flooding Concerns – Excessive stormwater flows can overtax drainage systems or sensitive streams during storms, causing local flooding if not properly controlled on-site during construction.
  4. Groundwater Protection – In some areas, allowing uncontrolled construction site runoff infiltration can contaminate aquifers, wells or subsurface infrastructure.
  5. Permitting & Oversight – Stormwater regulations require appropriate planning, erosion control measures, best practices, inspection regimes and agency oversight to minimize downstream and environmental impacts from development sites.

In summary, stormwater regulations aim to reduce downstream hazards to water quality, habitats, flooding risk, groundwater resources and public/private infrastructure from uncontrolled construction site discharges. Proper runoff management prevents long term environmental harm.
