Keep records up to date. Without proper slope protection, a serious erosion problem known as "beaching" can develop on the upstream slope. Method A is used where the stability of the rock slope protection is considerably dependent on the manner in which the individual rocks are placed. 6'' min. Slope protection is usually needed to protect the upstream slope against erosion due to wave action. For details about concrete production, review Section 4-90, Concrete, of this manual. These supersede the previous Caltrans Riprap Sizes.
