The scope of the project was the preparation of a conceptual design of a flood control
levee for the Alameda Flood Control District. The source of flooding was Alameda
Creek, also known as Zone 3A, Line A. The length of the levee study reach measured approx. 3.0 miles.
The nature of our work specifically addressed the complexity of levee design
criteria with regards to FEMA's certification requirements. Specific attention was
given to embankment stability, seismic criteria requirements, interior drainage,
and the 3.0 feet freeboard requirement, for protection against the 100-year flood.
All of the work was in compliance with Paragraph 65.10 of the NFIP Regulations.
This project included: geotechnical engineering analysis of the earth embankments
of seven (7) levee reaches and hydraulic analyses of Alameda Creek, using HEC-RAS.
