b. Application of Policy for Multiple Purpose Facilities.
Where measures are formulated to serve both HSDR and navigation, an
allocation of multiple purpose joint costs must be made and the joint
costs shared in accordance with the purpose to which they are
allocated along with any specific costs for features which serve only
one purpose. This cost allocation must include operation,
maintenance, repair, replacement, and rehabilitation responsibility
under the HSDR purpose. No cost allocation is required where a
measure is formulated to serve a single purpose but results in
incidental benefits, provided that the single purpose feature
maximizes net benefits. For example, a breakwater formulated to
provide HSDR, which is part of a NED plan, may produce incidental
navigation benefits but would be cost shared as an HSDR feature.
Conversely, a breakwater formulated to provide reductions in
transportation costs and/or increased net income to commercial
navigation activities may produce incidental HSDR benefits but would
be cost shared as a navigation feature.
