White Slough, Sec. 205

WHITE SLOUGH
CONTINUING AUTHORITY, SECTION 205

PROJECT LOCATION AND DESCRIPTION

The project addresses both tidal and fluvial flood protection for flood-prone areas adjacent to White Slough, a tributary of the Napa River that drains a portion of northwestern Vallejo, California. The recommended plan was to provide 100-year tidal and fluvial flood protection by utilizing White Slough as a detention basin for floodwaters from Austin Creek during the winter months. Other features included floodwalls on Austin Creek, removal of fill material at the Sereno Street extension, enlargement of culverts at Redwood Street and Valle Vista Avenue, and removal of a culvert and construction of a weir on Austin Creek. Placement of flap gates on the enlarged culverts under Highway 37, which were installed in October 2004, allow for increased tidal exchange in White Slough during the dry season.

ISSUES AND OTHER INFORMATION

  • The Vallejo Sanitation and Flood Control District is the Non-Federal Sponsor (NFS).
  • The Feasibility Study (FS) was completed in FY 02, and the Project Cooperation Agreement (PCA) was signed in September 2003.
  • In June 2008 the Corps conducted a Value Engineering (VE) study on the completed design with the objective of lowering the estimated cost. However, even with incorporation of the VE proposals, the overall construction cost of the project is projected to exceed the Federal limit.
  • The results of the VE study confirmed that the scale of the proposed solution had grown to be larger than could be supported by the CAP program. As a result the Project Cooperation Agreement will be terminated and the project closed out.
  • This project did not receive funds from the American Recovery and Reinvestment Act of 2009 (ARRA), Title IV, Pub. L. No. 111-5, 123 Stat. 115, Feb. 17, 2009.
