PA DEP FIGURE 15.2 Extension of Primary Rock Riprap Protection Area NOTE: Upstream and downstream ends must be keyed into the bank as per GP-3 requirements. 363-2134-008 / March 31, 2012 / Page 306
GABIONS and Reno mattress have been used to stabilize stream banks for many years. Results have been mixed. While successful in many locations, gabions have failed where undermined or where the wire baskets have been damaged by abrasion or corrosion. Therefore, before specifying gabions for streambank stabilization, consideration should be given to the available substrate, pH, and anticipated sediment transport of the water. If these are not suitable, another form of stabilization should be considered. York County Conservation District Where gabions or Reno mattresses are proposed, they are typically installed as shown in Figure 15.3 or 15.4. As with other types of stabilization, sufficient details should be provided on the detail sheets to ensure their proper installation, and supporting calculations should be included in the narrative to show they are properly sized. Gabion and Reno mattress installations should be designed according to manufacturers’ specifications. Special attention should be given to preventing scour at the upstream and downstream ends of the baskets. Appropriate means to prevent undermining should also be taken. 363-2134-008 / March 31, 2012 / Page 307
