Which ground cover is best applied to moderate to steep slopes and in stormwater conveyances?

Hydroseeding
Rolled erosion control products (RECPs)
Gravel
Grass sod

The correct answer is: Rolled erosion control products (RECPs)

Rolled erosion control products (RECPs) are particularly effective for use on moderate to steep slopes and in stormwater conveyances because they are designed to stabilize the soil quickly and effectively. These products typically consist of biodegradable materials that help to reduce erosion by providing immediate ground cover and promoting the establishment of vegetation. The physical structure of RECPs means that they can withstand the forces from water flow better than other options, making them ideal for areas prone to runoff. In contrast, hydroseeding, while beneficial for many applications, can take longer to establish and may struggle on steeper slopes if the mixture does not adhere well to the soil. Gravel can provide some stabilization, but it generally does not establish vegetation and thus lacks the erosion control that vegetation offers. Grass sod can definitely reduce erosion, but it requires a flat surface for installation and proper maintenance to thrive. Therefore, RECPs stand out as the most suitable choice for managing erosion and sedimentation in environments with challenging slopes and water flows.
