Abstract/Artist Statement

The goal of this project is to increase the flood rating of the levees within the Natomas Basin, from their current 30-year rating, up to a 200-year flood protection rating. The work contained in this project is for the portion of the levees located 500 feet upstream and downstream of Riego Road. The project involves the following primary tasks. First, a HEC-RAS hydraulic model will be developed and used to determine the 100-year and 200-year design water surface elevations; these values will be summarized in a table, and will be found in the hydrology and hydraulics (H&H) report. Second, from the data in H&H report, a geotechnical report will be developed; this report will contain seepage and slope stability analyses and calculations. Third, to comply with the California Environmental Quality Act (CEQA), the environmental impacts of the project will be investigated, and the necessary actions taken (i.e. Negative Declaration, Environmental Impact Report, etc.). Fourth, using all of the data gathered above, two alternative designs will be developed and compared to the a design proposed by HDR, Inc. Finally, based on client acceptance and recommendations, one of these alternatives will then be implemented.
