Document Description
The project will consist of cone penetration tests (CPT) and soil borings to acquire lithologic and piezometric data from the levee and its foundation. All borings will be drilled in the center of the levee crown. Standard levee drilling procedures will be followed. The borings will be approximately 100 feet deep, and backfilled with high-solids bentonite grout from the bottom up using a tremie pipe. The project will take approximately two weeks to complete which will be completed before March 1, 2007. The purpose of the project is to gather information essential to assessing causes and possible solutions to under seepage affecting the Tisdale Bypass' south levee. Residents and landowners protected by the Sacramento River flood control project and California taxpayers are the ultimate beneficiaries of this work.
