construction in a floodway (Correspondence, June 9, 2000, Attachment B, Page B-11). They reviewed their Natural Heritage Program data base and found that no species listed on state or federal lists as threatened, endangered, or rare are reported to occur in the project vicinity. The IDNR recommends the project include measures to minimize environmental and aesthetic impacts, such as bioengineering techniques, native glacial stone or logs for bank stabilization, and lunkers or other structures to enhance aquatic habitat. They said, "Do not use heavy equipment in the channel," and requested inclusion of riverbank fishing access in the plans. 4.14 Approval for construction in the floodway would be obtained from the IDNR prior to construction. The project is designed to minimize disruption to the environment. The North, Shore Drive protection site has been modified to include a bio -engineered upper bank protection, which will minimize the number of larger trees required to be removed. Project funding, pursuant to Section 14 of the Federal Flood Control Act. of 1946, is specifically for emergency streambank protection and does not allow for funding of amenities such as lunker boxes or A jacks, unless the full added cost is supported by a not federal entity. 4.15 Some equipment operation in the riverbed will be necessary because of limited site access and because of load limits on the upper slope at North Shore Drive due to slope instability. In -- water equipment operation will be limited as much as possible to within the area where the riprap will be placed and preference would be given_ to smaller equipment where possible. Any equipment operation or travel on the riverbed outside the excavation area shall be limited to a single path to limit the area directly disturbed. Riverbed travel shall be limited to that necessary for construction. 4.16 The IDNR. Division of Historic Preservation and ArchaeoloRv: The IDNR Division of Historic Preservation and Archaeology provided comments on the proposed project pursuant to the National Historic Preservation Act (Correspondence, February.21, 2000, Attachment B, Page B-12). For all three proposed projects and sites, they concur with the Corps' findings that there are no historic properties within the area of potential effects of the project. They request, as specified in 36 C.F.R. 800.11 [d], that once complete, the documentation be made available to the public and all interested parties. Additionally, they requested that if the project scope changes or if artifacts or bones are discovered, that the work stop and their office be notified within 2 days. 4.17 Cultural resource identification and evaluation efforts are discussed in this Environmental Assessment, which will be made available federal, state, and local agencies and the general public. Contract specifications will designate that, if during construction the contractor observes unusual items that might have historical, archeological, or cultural value, the - contractor shall protect those items and immediately report the find to the contracting officer so that the IDNR Division of Historic Preservation may be notified. 4. i 8 The Indiana Departmetut of Envirotuniental >vianap-eiimit requested the Cops submit a completed application packet for Section 401 water quality certification, including final construction methods, materials, amount of excavation and/or fill, and any re -vegetation plans
