Steep slopes on a construction site can lead to some problems when talking about erosion control and water runoff. Slopes greater than 3:1 allow water to quickly run down the slope leading to erosion and possible water damage downhill. In this month’s development digest, we discuss slope surface roughening techniques and why they are a beneficial practice on an exposed slope during construction.
What is slope surface roughening and what is the purpose? Slope surface roughening is the act of roughening up or raking the surface of a slope horizontally to create grooves, bumps, and depressions. These bumps and depressions on the slope serve multiple purposes including:
Two main methods to roughen the slope are commonly used:
Slope surface roughening is a tried and proven practice that works effectively to assist in the battle against soil erosion and water runoff. Whether using a bucket with teeth, equipment tracks, or any other method that roughens the slope, the creation of the grooves and depressions is a great practice to protect the soil and the water during the construction phase of a project. More information and specifications can be found in the Ohio Rainwater and Land Development Manual which is linked below.
