DAM & LEVEE REHABILITATION
Great Lakes E&I is highly experienced with dam and levee rehabilitation projects. These projects typically involve repair of damaged or eroded levee embankments, slope drainage modifications, and shoreline restoration. Construction methods include excavation of slump areas or unsuitable embankment materials, installation of stabilization or drainage fabrics, and placement of rock slope protection material, such as riprap. Great Lakes E&I’s experience in this area includes projects for public sector agencies such as the USACE, Bureau of Reclamation, and local flood control agencies.
PRADO DAM DIKE PROJECT
CALIFORNIA INSTITUTION FOR WOMEN
- 250,000 CY of subgrade and ponding area excavation

The Phase 2, Prado Dam California Institution for Women (CIW) Dike project is a portion of a larger Prado Dam Project in the City of Chino, San Bernardino County, California, approximately 45 miles southeast of downtown Los Angeles. The dike is located within and along the northern boundary of the Prado Dam Reservoir Basin, approximately 4 miles north of Prado Dam. The planned raising of the Prado Dam Spillway will increase the inundation elevation of Prado Basin to 566 feet and result in an expanded inundation area. Note that while the CIW facility is not within the inundation boundary under existing conditions, it will be within the inundation boundary after the planned spillway raising is constructed. The purpose of the CIW Dike project was to provide the California Institute for Women with flood protection from the Prado Dam Reservoir up to elevation 566 feet.
