<br />, <br /> <br />, <br /> <br />V. PLAN OF DEVELOPMENT <br /> <br />~ <br /> <br />A. Project Description <br /> <br />~ <br /> <br />The objectives of this study are to define the main seepage mecha- <br />nisms for Santa Maria Dam, identify and cost potential methods of <br />controlling or eliminating the seepage, and compare those costs to <br />potential benefits (increased reservoir storage) delivered from the <br />rehabilitation. A recommended method of controlling or eliminating <br />the seepage will be developed if the value of the benefits exceeds the <br />estimated cost of repair. This recommended method will be justified <br />and described in detail. <br /> <br />"III <br /> <br />"III <br /> <br />~ <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />The current reservoir storage hold order restricts storage volume <br />to 32,000 acre-feet. The hol d order was imposed due to concern over <br />embankment integrity with highE!r levels of seepage within the right <br />abutment area (> 1.0 cfs). <br /> <br />The program of study includE!d the following: <br /> <br />1. Embankment and reservoir inspection and surficial geology. <br /> <br />2. Geotechnical and geophysical investigation. <br /> <br />3. Analysis of data and evaluations to determine seepage <br />mechanisms. <br /> <br />4. Define potential remedial measures and costs. <br /> <br />V-I <br />
