What must nonstructural controls relate to in storm water management?

Nonstructural controls in storm water management focus on the operational processes that can be modified or improved to reduce pollutant runoff and enhance water quality without necessarily constructing physical structures. These controls prioritize management practices, policies, and education to achieve effective storm water management. Examples include implementing best management practices (BMPs), altering maintenance routines for equipment, and developing standard operating procedures that minimize the potential for storm water contamination.

While infrastructure improvement, employee training initiatives, and water quality monitoring are important elements of an overall storm water management plan, nonstructural controls are specifically centered on modifying operational practices and processes to achieve better outcomes in storm water quality and quantity. This distinction is vital for effective management of storm water and reducing environmental impacts.
