PROJECT DESCRIPTION
This is a requirement to conduct repairs due to high water levels which, in early 2017, damaged levees throughout California's Central Valley. Levee 1394-11 is located in the Walnut Creek System along Grayson Creek. The extent of the damage is approximately 40 ft. long x 20 ft. wide (downslope). Levee erosion repair is needed to re-establish the levee to the as-built condition.
The waterside levee slope generally ranges from 2H:1V to 3H:1V within the site area with a slope length of approximately 45 feet from the levee hinge to the bottom of the slope. The slope failure is located in the lower half of the levee, beginning approximately 22 feet below the hinge. The failure extends over an area approximately 100 feet long and 20 feet downslope, with a head scarp approximately 4 feet high.
Tension cracks up to 2 inches wide and 6 inches deep are present in the levee near the failure scarp, as well as along the levee hinge above the failure.
For site 1394-11, USACE recommends that the slump on the left bank of Grayson Creek be stabilized with a rock blanket at the toe of the levee slope. The site is underlain by Bay Mud and therefore sensitive to settlement and foundation failure under new loads.
The proposed alternative generally includes installation of a 4 foot thick rock blanket for the purposes of stabilizing the levee toe. All construction near this site must be staged in order to allow for gradual consolidation/settlement of the Bay Mud. A site length of 130 feet has been selected which includes the 100 foot damaged section, a 10 foot long transition zone on the southern end of the site, and a 20 foot long transition zone on the northern end of the site. The extents of the repair site should be verified during final design.
Depending on foundation conditions encountered in the field, a layer of high strength geotextile may be required beneath the rock. The rock should be installed in three stages. A 2-foot thick lift should be placed and then construction should be paused for two to four weeks and settlement should be monitored to determine when settlement stops. Once determined, construction can resume and the next 2-foot lift should be placed. The quarry stone should be placed below water level on the bottom of the channel and extend up the damaged section of the levee slope such that the stone has three points of contact with other stones. The outside edge of the quarry stone should follow an approximate 4H:1V slope. The total volume of quarry stone required for the repair is estimated to be approximately 1,100 cubic yards.
