Veg. Riprap | Soil & Grass Riprap |
| San Lorenzo River, Fern Canyon showing the original slide
        in Winter '96-'97 and subsequent repair. The slide pushed the river into
        the opposite bank, threatening homes. The riprap was built to protect the
        homes, but without vegetation. A few years after installation, an attempt
        was made to revegetate the riprap. The later photos were taken in 2004,
      showing that the area has naturally revegetated with alder. | ||||
