Description: After a record flood volume had eroded out approximately 40-feet of area adjacent to the river, the Kim Residence was in eminent danger of being destroyed unless immediate action was taken to stabilize a 300-foot long portion of the river bank. American Engineering Corporation was contacted to lead the permitting, design, and construction process to install Emergency Riverbank Stabilization measures in order to prevent the existing residence from obtaining future structural failure. With the use of modern stabilization techniques such as hog fuel mulch, placement of fir and hemlock seedlings, live stalking, anchoring of large woody debris, cabled cottonwood crib walls, rock lining, and large boulder flow control, the river bank was stabilized. This project was constructed under the supervision of our Sr. Civil Engineer/Hydrologist and obtained final permit review with several agencies after the construction had already been completed. This ensured that the timing of the normal permitting process would not allow for further damage of the existing structure. Because of American Engineering Corporation's knowledge of stream bank stabilization and emergency repair permitting techniques, this project was and remains successful today.
