 Soil loss generated from gentle and moderate slopes subject to sheet and rill erosion can be determined using the [[Soil Loss and Sediment Discharge|Universal Soil Loss Equation (USLE)]] model. Steep slopes and areas of concentrated flows cannot be modeled using the USLE methodology, and instead, are subject to prescriptive compliance.
-Prescriptive compliance should be established by identifying areas and designing appropriate measures in the erosion control plan.

 Once areas identified as needing prescriptive compliance are identified and clearly defined in the plan, appropriate measures and specifications need to be designed, as detailed below.
-====Bare Soil====
+====Practices====
-  * Areas that do not drain to sediment traps must limit the duration of soil exposure to no more than 30 days.
+  * Design and implement approved stabilization practices, typically [[seeding]] with [[Erosion Matting]].
-  * Areas that drain to sediment traps must limit the duration of soil exposure to no more than 90 days.
+  * Design stable diversion of off-site runoff around slopes.
+  * Specify [[silt sock|slope interruption devices]] on slopes.
-====Channel & Slope Management====
-  * Design and implement approved stabilization practices, typically [[Erosion Matting]].
-  * Provide stable diversion of off-site runoff around slopes.
-  * Provide [[silt sock|slope interruption devices]] on slopes.
 ====Stabilization====
-  * Areas left inactive for more than 14 days must be stabilized immediately.
+  * Areas that do not drain to a sediment trap must be stabilized within 30 days.
-  * Areas at final grade must be stabilized immediately.
+  * Areas that drain to an appropriately sized [[sediment trap]] must be stabilized with 90 days.
+  * Areas left inactive for more than 14 days and those at final grade must be stabilized immediately.
