The proposed monitoring and evaluation plan is presented in Section 10; and operation,
maintenance, repair, and rehabilitation considerations and responsibilities are discussed in Section
11. A detailed cost estimate of al1 project features, including construction, operation,
maintenance, repair and rehabilitation, and monitoring, is presented in Section 12. Real estate
requirements or easements to construct the project are discussed in Section 13. A tentative
schedule for planning, design, construction, and completion of the selected plan is shown in
Section 14. Section 15 describes implementation responsibilities and views. Public and agency
coordination is discussed in Section 16. Conclusions and recommendations are summarized in
Section 17, Sections 18 and 19 provide a list of the DPR preparers and a draft Finding of No
Significant Impact (FONSI), respectively. An evaluation in accordance with EPA's Guidelines
for Specification of Disposal Sites for Dredged or Fill Material (40 CFR 230) is contained in
Section 20. Section 21 provides literature cited. Attached to the DPR are two appendices, which
include details regarding engineering, environmental and cost studies. Appendices are included
in separate volumes (Volumes n and 1lI).

2. SITE SELECTION PROCESS

a. General Eligibility Criteria: The Reaffirmation Report (U.S. Army Corps of
Engineers 1990) describes the various aspects of the mitigation project, including the general
criteria to be used in selection of non-public sites for acquisition and development. These criteria
are as fol1ows: (1) sites in private ownership will be acquired on a willing sel1er basis to the
extent possible; (2) sites will general1y have a minimum size of 100 acres; (3) the total acreage
acquired and/or developed in each State will be approximately 28,950 acres in Missouri, 9,600
acres in Iowa, 7,200 acres in Nebraska, and 2,350 acres in Kansas; (4) areas selected must be
compatible with the authorized purposes of the Missouri River Bank Stabilization and Navigation
Project and will have no adverse effects on navigation, on the carrying capacity of the existing
levee systems, or on the flood-carrying capacity of the existing floodway; (5) emphasis is to be
given to acquiring remaining larger contiguous tracts of bottomland timber, wetlands or former
wetlands that can be restored, areas suitable for development of terrestrial forest and grassland,
and areas where chutes and backwaters can be restored; (6) acquisition of agricultural land should
be limited, except where the area has high potential for development or where a willing sel1er is
available; (7) acquisition will be confmed to the meander belt; (8) sites for chute and backwater
restoration will undergo an engineering, economic, and environmental feasibility determination;
(9) public access to areas will not be a determining factor in acquisition; (10) sites chosen for
chute, backwater, or wetlands restoration wilJ include enough adjacent land to allow establishment
of perimeter habitats; (11) sites chosen for acquisition and/or development will be based upon
State and Federal agency input and support; and (12) estimated operation and maintenance costs
wilJ also be considered in the site selection process.

In addition to these criteria, the States provided an initial screening and prioritization of
their recommended acquisition and development sites. The Kansas City (CEMRK) and Omaha
(CEMRO) Districts evaluated the engineering feasibility of developing certain State-owned lands
and ranked the sites according to the potential for success or failure. Proposed projects are
