Which type of inlet protection does not utilize nonwoven geotextile according to MDE's 2011 Handbook?

The choice regarding inlet protection that does not utilize nonwoven geotextile is standard inlet protection. Standard inlet protection is typically designed to facilitate sediment removal while allowing stormwater to flow into the drainage system effectively. In practice, it often combines rigid materials and structural components to secure the inlet and keep sediments out. This design approach means that nonwoven geotextiles, which are commonly used in other forms of inlet protection for their filtering capabilities, are not a component of standard inlet protection.

In contrast, other types of inlet protections like at-grade, curb, and gabion inlet protections often incorporate nonwoven geotextiles to enhance their sediment control functions, providing additional filtration and preventing sediment-laden water from entering storm drains. Understanding the specific materials and designs associated with each form of inlet protection is crucial for effective erosion and sediment control practices.
