Assuming it takes ten years to build the project, a fifty year "useful life" initial maintenance costs equal to 5% of the capital cost, monitoring costs equal to 1% of the capital cost 3% inflation during construction and 6% inflation of maintenance and monitoring costs over the 50 year operating costs then the required cash flow for bonded debt service and operations will be about $3 billion per year and rise from there. In the alternative DWR could use the same maintenance approach used on the Oroville Dam. Skip all major maintenance until there is a failure. ktg Oaklandkennethtgibsonhttps://www.blogger.com/profile/01857338982736800433noreply@blogger.com
