Project: Geotechnical Evaluation of Alameda Creek Levees, in the Cities of Fremont and Union City

Description: Alameda Creek levees were constructed by the U.S. Army Corps of Engineers and maintained by the Alameda County Flood Control and Water Conservation District. The levees are currently provisionally accredited by FEMA, but are at risk of becoming unaccredited due to lack of geotechnical information. The geotechnical evaluation will include performing a field geotechnical exploration program, soil testing, engineering analysis, and final written report. Alameda Creek is located within Alameda County. Its watershed is located within the Coast Range Mountains east of the San Francisco Bay. The creek flows northwesterly for approximately 25 miles, then westerly through Niles Canyon for approximately five miles, were it enters the Alameda Creek flood control channel. Project coordinates are 37.42N, 122.04W.

Reference Number: 3860-P84-099

Implemented By: Alameda County Flood Control and Water Conservation District

Objective: A levee geotechnical evaluation report is a primary document needed to fulfill the requirements of a Provisional Accredited Levee Agreement with FEMA and is also necessary to achieve levee certification. A geotechnical report will confirm that the levee system can contain the base water surface profile or identify at what level elevation the levee is likely to fail. It can also identify areas for improvement. The objective of this type of project is to produce such a report for each flood control structure evaluated.
