What is the maximum slope of a stormwater wall allowed before adding slurry?

• A. 1 to 1
• B. 2 to 1
• C. 3 to 1
• D. 4 to 1

Answer: (B)

The maximum slope of a stormwater wall that is allowed before adding slurry is 2 to 1. This ratio indicates that for every 2 units of horizontal distance, there can be 1 unit of vertical rise. A 2 to 1 slope is considered stable for various soil types and is generally manageable for construction and engineering applications, ensuring that water can be effectively drained without risking erosion or failure of the wall. When slopes are steeper than this, specifically those close to or exceeding 1 to 1, additional stabilization measures such as slurry are typically required to prevent the risk of slope failure. Slurrying helps hold the soil in place and offers increased resistive force against sliding or erosion. Therefore, the stability and integrity of a stormwater wall are prioritally addressed by adhering to the specified maximum slope of 2 to 1 before intervention is needed.
