The full Capital and Life Cycle Costs of Rebuilding Riverside Dam were not realistically represented in the ESR and could well end up costing the taxpayers more than double what was presented to the public and City Council. A Rebuilt dam would be considered a new dam, not a repair or expansion of an existing weir, with an assessed High Hazard Potential, and is located within the City of Cambridge in a location that could place multiple residences and businesses at risk in the event of severe flooding or a dam breach. ORA and Partners submit that this Project goes far beyond the screening process provided by a Schedule B, Class EA. Consequently, we submit that this is a major project that should fall into a higher level of assessment.
