Susquehanna River Impact & Accretion Study
The 2015 Aberdeen Proving Ground (APG) - CSSC Joint Land Use Study recommended assessing the viability of receiving dredging spoils, developing a long-range plan for sea level rise, quantifying regional sea level, and considering adoption of sea level rise ordinance. The Susquehanna River Impacts and Accretion Study, in consultation with EA Engineering, will build upon and use existing data to evaluate, at a regional scale, the viability of the shoreline surrounding the Susquehanna Flats and Upper Chesapeake Bay with regard to specific management issues identified in the Joint Land Use Study (JLUS). Tasks include:
- Assessment of existing conditions (GIS mapping of erosion areas, baselining of the upland bank, beach intertidal and nearshore areas in comparison to historical conditions); evaluating of the erosion patterns, wave climate and prioritization of eroding sites posing threat to Bay water quality
- Assessment of sediment accretion (causes/factors), the cost of dredging (so as to maintain a navigable channel), and use of dredge spoils
- Development of regional strategies to address impact from sea level rise (including construction of resiliency measures)
- Study of implications of Susquehanna River Flats management with regard to water quality (i.e, the Clean Water Act)
- Assessment of resulting implications of any strategy on the APG installation (e.g, management) and its missions
