Document Description
The Project includes removing the upper two-thirds of select riprap from 1,245 linear
feet of the Merced River's bank between slightly south of Ahwahnee Bridge to Sugar
Pine Bridge, 849 feet of which are below the ordinary high watermark (OHWM).The
selected portion of riverbank receives high velocity flows due to the undersized
Sugar Pine Bridge and the extreme horse-shoe bend in the river, consequently
needing to keep a portion of the riprap closest to the river's edge to prevent severe
erosion. To access the riprap safely and effectively, the Discharger will remove up to
five conifer trees that have grown at the riverbank and are outcompeting riparian
hardwood species, if needed. All riprap that is removed will be taken to two existing
staging areas.
