Which of the following is a major contributor to increased maintenance of stormwater systems?

Soil erosion is a significant contributor to increased maintenance of stormwater systems because it leads to sediment accumulation in stormwater infrastructure. When soil erodes, sediment is often washed into storm drains, retention basins, and other stormwater management facilities. This accumulation can reduce the capacity of these systems, leading to decreased effectiveness in managing stormwater runoff. As a result, increased sediment buildup necessitates more frequent maintenance activities, such as cleaning out sediments and potentially repairing damaged infrastructure to ensure proper functionality.

Additionally, erosion can affect the surrounding landscape, facilitating further sediment transport and requiring ongoing interventions to stabilize soil and minimize further erosion. This cycle of erosion and sedimentation creates a continuous demand for maintenance work in stormwater systems. In contrast, effective landscaping, use of permeable materials, and regular inspections, while important for the overall health and efficiency of stormwater systems, do not directly contribute to increased maintenance in the same way that soil erosion does.
