Document Description
The proposed project is located on the Zone 6 Line K-1 flood control channel (Washington Creek) between Alice Court and Olive Avenue in the City of Fremont. The project involves restoring an approximately 1,300-foot-long reach of Zone 6 Line K-1 by reestablishing natural creek-channel characteristics. The existing channel alignment will be maintained, except where it is necessary to move the channel away from previously eroded slopes and adjacent properties. The channel bed will generally be raised to a more uniform gradient to restore the channel thalweg to historical elevations. Riffles and pools will be constructed at select locations to provide grade control and limit degradation of the channel bed. The channel-corridor will be widened and creek bank slopes will be regraded to accommodate the channel widening. Creek bank slopes requiring steeper inclinations will be stabilized by constructing vegetated soil lifts, and installing rock planted with live cuttings along the toe of slope. Additional rock will be placed to transition from the existing concrete culvert aprons to the earthen channel at both ends of the project. The existing gravel maintenance road along the south side of the channel will also be resurfaced.
