How is stormwater management incorporated into site design?

• A. Parking count optimization
• B. Solar orientation for energy savings
• C. Drainage design, sediment control, green infrastructure, and compliance with local stormwater regulations
• D. Building height restrictions

Answer: (C)

Stormwater management is addressed in site design by planning how rainfall is collected, conveyed, treated, and released, using drainage design, sediment control, green infrastructure, and adherence to local regulations. Drainage design determines how runoff is collected, routed, and discharged to prevent flooding and erosion while protecting downstream conditions. Sediment control minimizes erosion and sediment transport during construction, keeping waterways clean. Green infrastructure—like bioswales, rain gardens, permeable pavements, and green roofs—treats and infiltrates or evapotranspire rainwater on site, reducing runoff and improving water quality. Compliance with local stormwater regulations ensures the design meets legal requirements for post-construction runoff, pollutant control, and ongoing maintenance. This integrated approach ties the built environment to watershed protection from planning through construction and operation. In contrast, adjusting parking count, solar orientation, or building height restrictions address other goals and don’t directly implement stormwater management.
