As a result, the alternatives for Union <br />Avenue boat chute reflect state-of-the-art boat chute engineering based on <br />local and international engineering practices. <br /> <br />DESCRIPTION OF ALTERNATIVES <br />Numerous alternative layouts were considered during <br />asssignment. As a result, five alternates were <br />engineering plan and profile. These included: <br /> <br />the course of this <br />laid ou t in both <br /> <br />1. Boat Chute Over the Existing Dam Face on the West Bank <br />2. Boat Chute Through the Existing Dam Face on the West Bank <br />3. Boat Chute Through the Existing Dam Face on the East Side <br />4. Boat Chute on the West Bank Adjacent to Existing Dam Structure <br />5. Boating Course on the West Bank By-passing the Dam <br /> <br />Each of the five alternatives are described both as to pros and cons. <br /> <br />EVALUATION OF ALTERNATIVES <br />A review of each of the five alternatives was conducted by the boat chute <br />deSign team in conjunction with state representatives. For this prupose, <br />five major feaSibility factors were considered. This represented a fatal <br />flaw analysis. <br /> <br />The five major feasibility factors consist of the following: <br /> <br /> <br />1. Water availability and sediment transport <br />2. Cost <br />3. Safety and liability <br />4. Site compatibility <br />5. Limitation of use <br />
