摘要

Begin with the end in mind. Integrating contaminated sediment remediation efforts with waterfront use and development, ecosystem restoration and habitat creation efforts can result in breakthrough opportunities to accomplish sustainable restoration of con- taminated water ways. Typically, the restoration of degraded aquatic systems follows a sequential path of isolated actions from source control to remediation to ecosystem resto- ration and property development. Each of these stages has focused objectives that are limited to meeting only the goals of that particular stage. For example, contaminated sediment remedial actions are typically evaluated and designed only to reduce the short and long term risks posed by the sediment to human health and the environment. Each of the alternatives in these stages are conceived and compared with one another using cri- teria that are typically important only to meeting the immediate objectives. With this potentially myopic approach, there are likely opportunities that are missed to creatively restore elements of the system or create new sustainable elements as a part of the reme- dial action or source control that could result in synergies that at worst could save costs and at best could help “sell” and potentially help fund the project and make an otherwise impossible project possible.
