What is a primary hazard associated with urban developments?

In urban developments, one of the primary hazards is increased sediment accumulation due to impervious areas. When land is developed, natural vegetation and soil surfaces are often replaced with impervious surfaces such as asphalt, concrete, and buildings. These surfaces prevent water from being absorbed into the ground, leading to increased runoff during rainfall events.

As this runoff flows over impervious surfaces, it can pick up sediment and other pollutants, which then accumulate in nearby water bodies. This sedimentation can have detrimental effects on aquatic ecosystems, disrupting habitats and degrading water quality. Additionally, the increased volume and velocity of the runoff can lead to erosion in other areas where the water is discharged, compounding the problem further.

This highlights the importance of effective stormwater management practices in urban settings to mitigate sediment accumulation and protect water resources. Understanding these hazards is crucial for Certified Erosion, Sediment, & StormWater Inspectors to ensure compliance with regulations and implement best management practices.
