Which technique is NOT associated with Low Impact Development (LID)?

Low Impact Development (LID) is an approach to land development that aims to manage stormwater and promote sustainability by mimicking natural hydrological processes. It incorporates various techniques that help to reduce runoff and minimize environmental impact.

Preserving native vegetation is a fundamental aspect of LID, as it enhances biodiversity, maintains local ecosystems, and helps with soil stabilization and water absorption. Similarly, the use of permeable pavements allows rainwater to seep through surfaces, reducing runoff and increasing groundwater recharge. Stormwater infiltration techniques are designed to facilitate the absorption of rainwater into the ground, thereby improving water quality and reducing the flow of stormwater into drainage systems.

Land grading, on the other hand, is primarily concerned with altering the natural contours of the land to facilitate drainage. While it may be necessary for construction purposes, it does not inherently align with the principles of LID, which emphasize preserving existing natural topography and minimizing disturbance to the landscape. This makes it the answer that is not associated with Low Impact Development, as it does not contribute to the goals of managing stormwater sustainably or reducing environmental impact in the same way that the other techniques do.
