Document Description
The Operator proposes to alter the streambed by constructing a secondary drainage overflow culvert due to sedimentation/flooding problems to SR 150 with the existing culvert. The new culvert will consist of two 2.1m reinforced concrete pipes to be installed above and offset from an existing 2.4m diameter reinforced concrete pipe. A boring machine will be used to drill a hole through the ground and a horizontal jack will push the new concrete pipe into place. Concrete headwalls will be installed at the inlet and outlet, and rock riprap will be placed below the inlet to dissipate energy. Rock will also be placed below the culvert inlet to protect against scouring below the headway, but will not impact the existing stream.
