current condition, should be included in this description. High quality color photographs are
especially important to enable the reviewer to visualize and appreciate the features and their
condition. The reviewers are normally unfamiliar with the project and are relying solely on the
content of the report to make investment decisions.
(b) Provide a history of project cost. Describe and display on an annual basis the
operation, maintenance, repair and rehabilitation cost history of the project. The maintenance,
repair and rehabilitation costs for the feature(s) proposed for rehabilitation should be shown
separately. Include a description of the important repair and maintenance activities on the
project.
(c) Describe and display instances of service disruption and emergency repairs. This
should include all significant episodes of service disruption. Describe the consequences to the
system (i.e., describe the socioeconomic effects of the disruption in service). The description of
each event should contain all the conditions that are relevant to the disruption of service, not only
those that are related to the feature's physical condition. These might include ice build-up,
impact damage from barges or debris, or rare natural events. The description and display should
include length of time the project and/or project feature was out of service and the costs
associated with each event. These costs are the emergency repairs and increased O&M after the
event, but attributable to the event, and project benefits which would be lost if this disruption of
service occurred under current conditions. State all figures in current dollars. The repair may
also change (reduce or increase) the frequency of future service disruptions and may reduce
future O&M costs. These possibilities should be considered and included in the analysis, if
warranted.
(d) Describe and document quantitatively historical changes in the service level capable
of being provided by the project. This should provide documentation on any chronic decline in
the capability of the project to produce beneficial outputs due to deterioration or other factors
related to a feature's physical condition. This information should be provided for at least the last
10 years. Special attention should be paid to the contribution of the feature(s) proposed for
rehabilitation, and to the degradation in service level.
e. Economic Considerations.
(1) Federal Interest. For the majority of cases, the Federal interest in an existing project
will be obvious. However, reasonable argument which shows a Federal interest, and in some
cases, a non-Federal interest (i.e., proposed cost sharing), will be provided in the report.
Emphasis shall be placed on project outputs and whether they serve priority purposes as defined
in the Annual Program and Budget request for Civil Works Activities, Corps of Engineers.
(2) Base Condition. The base condition is the alternative which all other plans will be
measured against. In comparison to other Corps planning studies, the base condition is
synonymous with the "without project" condition. The base condition assumes that the project
will be operated in the most efficient manner possible without the proposed rehabilitation.
Should the project benefit stream be interrupted due to unsatisfactory feature performance, it is
assumed that emergency funds will be available to fix the feature. For the economic analysis,
allowance must be made for the effect of the repair on the reliability of the feature. Considerable
risk and uncertainty is inherent in the base condition. The timing, frequency, and consequences
of system disruption are all unknown and must be estimated. The analysis should explicitly
