Costs for RP-1 include expected post-event response costs based on methodology described in Memorandum: Methodology for Estimating
Expected Loss from Damage to Remedies (CH2M HILL, 2009e).
NOTE: The above costs are presented rounded to three significant figures.
NOTE: The above cost opinion is a Feasibility Study-level estimate with a nominal accuracy of –30 percent to +50 percent (–30/+50%).
NOTE: The above cost opinion is in 2009 dollars and does not include future escalation. The order-of-magnitude cost opinion shown has been
prepared for guidance in project costs, actual site conditions, productivity, competitive market conditions, the final project scope, the final
project schedule, and other variable factors. As a result, the final project costs will vary from those presented above. Because of these factors,
funding needs must be carefully reviewed prior to making specific financial decisions or establishing final budgets.
NOTE: Active treatment is not included in OU 2 Alternatives (a) and (b); therefore, total flows for Alternatives 3+(a) and
3+(b) and Alternatives 4+(a) and 4+(b) will be identical.
NOTE: The O&M Cost (Annual Average) is calculated by dividing the O&M Cost (30-Year NPV) by a factor of 12.409 to account for the
30 years at 7%.
