SCOPE
Dike 8 is located along the southern rim of Folsom Lake about 550 feet north of the intersection of East Natoma Street and Folsom Point entry road in Folsom, California. The dike was constructed in 1954 with a 16-foot wide crown and 2.25H:1V downstream slope. Waste fill was placed on the upstream slope from the existing crown down to about 150 feet at a slope of approximately 13H:1V. At the maximum section, Dike 8 is approximately 20 feet tall. The dike is approximately 700 to 800 feet in length. The 3.5 foot raised will consist of earth fill from toe-to-crest on the downstream slope. The raised crest width will be approximately 25 feet. Along the existing downstream slope and toe of the dike, a chimney drain and key trench excavation that extends a minimum of 4 feet below the existing ground surface to remove surficial soils and weathered rock (amphibolite schist). Materials for drain rock, filter sand, and embankment fill will need to be imported during construction. Rock slope protection will be installed on the upstream slope. A stock pile of large sized granite (up to 6-8 feet) is available near Dike 8 for use, in addition to the option of importing the riprap materials Howard Gregory, Contract Specialist howard.gregory@usace.army.mil Phone: 9165575217
