The City of Omaha and the Program Management Team (PMT) are utilizing the Envision Sustainability Rating System for several of the larger Long Term Control Plan projects. Envision is a rating system developed by the Institute for Sustainable Infrastructure that is applicable to infrastructure projects such as the CSO projects. The City and PMT use Envision as a tool to ensure that CSO projects are designed, constructed and operated in a manner that considers overall impacts on the community and on stakeholders impacted by individual projects; minimizes consumption of resources; minimizes negative impacts on the natural environment and, wherever feasible, enhances the natural environment; and considers resilience to future conditions. Through the use of Envision we hope to lower the total life-cycle costs of CSO projects to rate-payers.
