Abstract: In partnership with the City of Atlanta and thirteen federal agencies, the Mobile District of the U.S. Army Corps of Engineers (USACE) is planning an urban stream restoration in Proctor Creek, Atlanta, Georgia. A two-part numerical modeling toolkit, the Proctor Creek Ecological Model (PCEM), was developed to support planning of this ecosystem restoration project. This report presents the second phase of model development (PCEM2), a numerical tool for computing environmental benefits of restoration actions, informing feasibility-level design, and facilitating restoration decision-making. PCEM2 contains four modules related to instream condition, riparian condition, hydrologic change, and watershed connectivity, these are combined into an overarching assessment of stream ecosystem integrity at the watershed-scale. The model was applied to compute ecological benefits of restoration actions at thirteen potential sites in the Proctor Creek watershed. Benefits were computed for 8,192 plans representing every possible combination of site and restoration action. When coupled with cost estimates, these data were used to conduct cost effectiveness and incremental cost analyses to inform the Tentatively Selected Plan Milestone of the USACE Planning Process. While parameterized for Proctor Creek, PCEM2 provides an adaptable, generic framework for computing watershed-scale benefits of stream restoration actions.
