dc.description.abstractIn partnership with the City of Atlanta and thirteen federal agencies, the Mobile District (SAM) 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 phase one of model development (PCEM1), a rapidly applicable site-screening tool for informing preliminary project decisions. PCEM1 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 the Proctor Creek watershed to screen 46 potential sites to 17 sites, these were continued forward at the alternatives milestone of the planning process. While developed in the context of Proctor Creek, PCEM1 provides a simple screening level model for comparing site-specific alternatives at a watershed scale, this could be adapted to other stream restoration sites or watershed studies. While developed for rapid application, the PCEM toolkit also represents a state-of-the-science approach for conducting watershed assessment and is deeply grounded in peer-reviewed approaches to stream restoration prioritization.en_US
