FEDERAL-AID POLICY GUIDE
December 9, 1991, Transmittal 1
G 6011.4
OPI: HNG-12
(1) An existing highway that remains in service without improvement until a water resources development project is funded should be relocated to a mutually acceptable location, or reconstructed, altered, or improved at the existing location, and should serve, as nearly as practicable, in the same manner and as well as the existing road. It should be designed to current standards adequate to accommodate the existing traffic.
(2) For water resources development projects undertaken by the Corps of Engineers and the Bureau of Reclamation, funding for roads isauthorized under Section 13 of the Water Resources Development Act of 1974 (Public Law 93-251), which is codified in the United States Code, Title 33, Section 701r-1 (Attachment 1). The Chief of Engineers and the Commissioner of the Bureau of Reclamation "are authorized to construct substitute roads to the design standards which the State or owning political division would use in constructing a new road under similar conditions of geography and under similar traffic loads (present and projected)." A projection of traffic for up to 20 years may be included in accordance with a defined State custom or established practice.
(3) For water resources development projects undertaken by agencies other than the Corps of Engineers and the Bureau of Reclamation,funding for affected roads should conform to the following principles:
(a) If the design of the existing highway is adequate for future traffic (20 year projection), no additional improvement should be made and the full cost of the highway relocation, reconstruction, or alteration should be borne by the water resources development agency.
(b) If the design is not adequate for future traffic, the highway may be relocated, reconstructed, altered, or improved to standards adequate for future traffic. In this case, the water resources development agency should bear the estimated cost of relocating, reconstructing, or altering the highway to current standards for existing traffic and Federal highway funds may participate in the additional cost of improving the highway to the higher standards necessary to accommodate future traffic.
(1) If a water resources development project has been authorized but not funded for construction:
(a) The water resources development agency should be advised that, if it so desires, the affected highway can be relocated at a new location that will not interfere with the future construction of the water resources development project, or reconstructed, altered, or improved on the existing location to accommodate the proposed water resources development project.
(b) The water resources development agency should finance any costs over and above the estimated cost of relocating, reconstructing, altering, or improving an existing highway without consideration of the proposed water resources development project.
(c) If it is found that a water resources development agency's cooperation in the joint financing of the relocation or improvement of an existing highway cannot be obtained and it is essential that the highway be relocated or improved prior to the construction of the water resources development project, Federal highway funds may participate in the cost of relocating the existing highway without consideration of the water resources development project, or reconstructing, altering, or improving the existing highway to the minimum extent necessary for the traffic estimated to exist during the interim period until the water resources development project is under construction. When thewater resources development project is later constructed, the highway should then be improved to accommodate it in accordance with paragraph 4b.
(2) If a water resources development project is under study but has not been authorized:
(a) The construction of new highways or the relocation, reconstruction, alteration, or improvement of existing highways through areas that may be inundated by reservoirs or other water resources development projects that are under study but not authorized should be called to the attention of the agency having jurisdiction over the water resources development project in order that it might attempt to obtain authorization for the project prior to the construction, relocation, reconstruction, alteration, or improvement of the highway.
(b) If it appears that such an authorization might be obtained within a reasonable time, every effort should be made to defer the highway work until such authorization is obtained. If the authorization is obtained, the policies outlined in paragraph 4c(1) should be followed.
(c) If it becomes apparent that the water resources development project will not be authorized for some time, if at all, the highway may be constructed, relocated, reconstructed, altered, or improved without regard to the possible water resources development project.
