Abstract/Artist Statement

The City of Stockton requires a levee repair at Shima Tract, located west of I-5 Freeway between Disappointment Slough and Fourteen Mile Slough. A real-estate developer has proposed to convert the farmland of Shima Tract into an urban community. The proposed design project addresses both the necessary levee improvements and stormwater and seepage control systems required to develop Shima Tract. Currently the levees protecting Shima Tract are not protected by the Federal Emergency Management Agency. Therefore, the proposed design must meet the requirements of Urban Levee Design Criteria (ULDC). The soil analysis was performed by reviewing existing boring logs provided by Kleinfelder. The existing levee was checked for seepage and slope stability at two cross sections. A new levee design will comply with the ULDC. The seepage analyses and slope analyses on all cross sections were completed by hand calculations and two geotechnical computer programs. To address stormwater runoff from future urban growth, a pump station was designed for the southwest side of Shima Tract adjacent to the levee. The pump station is capable of handling the design flow and calculated discharge volume for urban development in accordance with City of Stockton design requirements. The pipe network will be concrete pipes in conformance with City of Stockton Standards. The project will require permits including but not limited to; California Environmental Quality Act, U.S. Army Corp of Engineers, and State of California Central Valley Flood Protection Board. An Initial Study and Mitigated Negative Declaration was prepared to reduce potential environmental impacts.
