Document Description
The excavation/removal of approximately 200,000 cubic yards (estimated to be approximately 300,000 tons) of aggregate material from the north side of the Cucamonga Dam, over a period of approximately seven months between mid to late 2015. At the end of this phase, the crosswalls will be functioning again to capture the much needed surface water from the higher mountain areas and percolate into the groundwater basin. Material will be moved to a location on the south side of the dam where approximately 200,000 cubic yards of material is already stockpiled. Existing and new material, will be sorted at the stockpile location using portable screens. The operator will be using the material for various construction and landscaping projects and anticipates that sorting/processing and depletion of the aggregate material will be completed within five years.
