Looking back on this project we are reminded of the importance of hidden infrastructure and the consequences of neglecting our aging system. This sinkhole on SE Yamhill in Portland appeared overnight and caused quite a disturbance to local traffic, routes to school and bus lines. Interlaken was quick to the scene to aid the Bureau of Environmental Services in stabilizing the ground not only to protect the surrounding community but to also protect those working on the failed private sewer lateral which caused the sinkhole.
