Work will include the provision of all materials and labor to provide for the removal of the existing spillway system and internal drainage structures from the Lake Inverness Dam (Category 1- high hazard), located in the Lakeside at Berkeley Manor subdivision. A new principal spillway system, consisting of reinforced concrete riser structure and a 60-inch reinforced concrete pressure pipe will be constructed in the dam. A new auxiliary spillway, consisting of an articulated block-lined channel. A portion of the embankment will be removed and re-compacted in order to construct the new spillways. A new internal drainage system will also be installed within the dam. Sediment accumulations in the lake bed will also be removed as part of this project
