i <br /> The absence of a maintenance dredging history for Reach III precluded projecting the frequency of <br /> future dredging operations . However, an assumed frequency of once every 5 to 10 years appears reasonable, <br /> based on operational considerations such as scheduling and contract procedures, as well as present shoaling <br /> patterns . Thus, depending on the interval between successive dredging operations, each maintenance <br /> operation in Reach III should produce a bulked material volume between 16 ,300 cy and 32 ,600 cy for <br /> placement in Site IR- 14 . <br /> Beyond satisfying a minimum capacity requirement, the management objective forthe IR44 dredged <br /> material management area is to process ( i .e . , decant and dewater) the dredged material efficiently and to <br /> operate the facility so as to extend its usefulness beyond the design service life. The design and construction <br /> of the containment facility establish the site ' s potential long-term efficiency, while its operating procedures <br /> intend to ensure the realization of this potential. Specific elements of site design and operation during and <br /> following dredging activities will be discussed in turn as they relate to site efficiency and local impacts. <br /> Accordingly, Section 2 .0 begins the management plan with a discussion of site preparation and design . <br /> Section 3 .0 presents operational considerations during dredging. Section 4.0 addresses post- dredging site <br /> management. <br /> 4 <br />
