American River Watershed Common Features Project
Levee Construction
Client: US Army Corps of Engineers
Location: Sacramento, California
Highlights: May 2018 - May 2020, Reach D Windows
Description:
The work includes removal of pipes crossing through the levee at the abandoned Bennett and Northern Pumping Stations, in addition to removing the concrete structures on both the waterside and landside.
The voids left by the removal of these facilities on the landside was filled and compacted as shown on the plans. The waterside structures was removed to the elevations shown on the plans, and stone protection placed as shown.
The levee was raised and enlarged to match the existing elevation of the raised and enlarged levee on either side of these pumping stations. The ramps and crown roads were installed as shown on the plans, with an aggregate base surface.
A portion of the Vestal Drain between Pumping Plant 4 and where it crosses underneath the Sankey Canal must be relocated to the south side of Sankey Canal. The drain must cross under the irrigation ditch near Bennett, and connect into the existing concrete drainage ditch at Pumping Plant 4.
