It is recommended that both the landward lock, the riverward lock and the dam at Lock & Dam no. 1, Minneapolis, Minnesota be completely rehabilitated. Based on studies completed to the date of this report, more detailed studies are required to firmly establish cost estimates, environmental effects, and the construction scheduling necessary to insure the work can be completed in the proposed two year construction period without delaying navigation. This Appendix discusses: Plan 1, Rehabilitation of Landward Lock Without Interruption of Navigation; Plan 2, Rehabilitation of Landward Lock with Temporary Use of Riverward Lock for Navigation; Plan 3, Rehabilitation of Landward Lock with Navigation Closed During Construction; and Plan 4, Rehabilitation of Both Locks Without Interruption of Navigation.
