Title

Bear River North Levee Erosion Sites Repair Project

Description

The proposed project site includes two locations (Erosion Sites 1 and 2) along the Bear River, south of the Town of Wheatland. Erosion Site 1 is approximately 250 linear feet long, with an area of 0.32 acres. Erosion Site 2 is approximately 500' in length and has an area of 0.35 acres. The erosion repair at Site 1 will involve removing existing soil and redistributing it as necessary to establish the desired slope configuration of 2:5:1. Stone shall be placed systematically beginning at the base of the embankment slope which will result in a stone dike that will support the placement of the riprap. For levee toe relpacement, the rock will be lpaced using a drag or clamshell-type bucket by excavator from the levee crown. Approximately 12" of bedding material, consisting of rock fragments of less than 4" in size, will then be placed along the slope. The erosion repair at Site 2 will involve removing existing soil and redistributing it as necessary to establish the desired slope configuration of 3:1. Stone shall be placed systematically beginning at the base of the embankment slope, which will result in a stone dike that will support the placement of riprap. For levee toe replacement, the rock shall be placed using a drag or clamshell-type bucket by excavator from the crown. Approximately 12" of bedding material, consisting of rock fragments of less than 4" in size, will then be placed along the slope.
