Compaction of created wetland subsoils is often required for stability and to limit groundwater losses, but failure to provide a suitably loosened surface soil rooting media is a common problem, particularly for deeper rooted forested wetlands. Remedies include managing soil placement and tillage operations in concert with seasonal/moisture constraints. Near-surface compaction can also drastically alter hydroperiod regimes away from intended target references. Deeper excavations of creation sites in the mid-Atlantic USA also commonly encounter potential acid-sulfate materials, which if allowed to oxidize, generate very low soil+water pH and phytotoxic conditions. Preconstruction testing, recognition and avoidance are critical; remedial measures include heavy liming and organic amendments and/or keeping these materials saturated year-round.

Wetland and fluvial restoration projects commonly include post-construction plans which detail actions to address issues related to routine maintenance, adaptive management and remediation. These three direct actions have one common goal: set the constructed project on a trajectory to realize the restoration objectives. In this webinar we will review these three direct actions, with an emphasis on (1) how the direct actions are typically differentiated during the pre-construction planning and design phase, (2) post-construction conditions that are difficult to anticipate and therefore plan around, and (3) strategies that can be used to address significant uncertainties involving future landscape conditions. We will review the San Clemente Dam Removal project to help illustrate routine maintenance, adaptive management and remediation, within the context of an action that will reset the Carmel River corridor to a new physical state.

This presentation provides an understanding of the Corps' perspective in review, approval, and oversight of mitigation projects where adaptive management has been used as an important tool for planning and response to challenges and unforeseen changes to those projects.


W. Lee Daniels W. Lee Daniels is the Thomas B. Hutcheson Professor of Environmental Soil Science at Virginia Tech in Blacksburg, Virginia. He received his Ph.D. in Soil Science from VPI & SU in 1985. Dr. Daniels areas of specialization include stabilization and restoration of disturbed lands including areas disturbed by mining, road building, waste disposal, urbanization and erosion. In particular, he has focused his research and consulting experience in wetland impact mitigation, mine reclamation, and soil-waste management systems. His teaching programs at Virginia Tech focus on soil geomorphology and landscape analysis with particular emphasis on the relationships among surficial geology, hydrology, soil patterns and long term landscape evolution processes. Major awards include the Reclamation Researcher of the Year by the American Society for Surface Mining and Reclamation (ASMR) in 1993, USEPA’s National Biosolids Utilization Research Award in 2000 and the Lifetime Achievement in Research Award by ASMR in 2012.

Shawn Chartrand Shawn Chartrand completed his PhD at the University of British Columbia, and he is presently a postdoctoral research fellow at Vanderbilt University. Shawn is interested in how mountain streams form and evolve due to changes in local to watershed scale conditions. He uses laboratory experiments, develops theory, numerical models as well as field-based programs to pursue his interests, and develop strategies to assist practitioners working on applied problems. He has worked professionally for Balance Hydrologics since 2000, during which time he built and continues to lead a river and wetland restoration program. His notable applied experience includes 8 years of work on the San Clemente Dam Removal project, Carmel River, CA, and 15 years of work using climate change projections to plan water supply and instream flows for salmonids with the City of Santa Cruz and other regional Cities.

Krystel Bell Krystel Bell recently became Regulatory Program Manager for the U.S. Army Corps of Engineers in Washington, D.C. Prior to this, she served as Mitigation Banking Specialist for the Sacramento District of the U.S. Army Corps of Engineers where she chaired the Interagency Review Team for multiple mitigation banks and in-lieu fee programs and worked on several of the District’s most complex regulatory actions. Prior to working for the Sacramento District, Ms. Bell worked as an environmental consultant and acted as a local representative for a County‐ level environmental program. Ms. Bell has extensive knowledge of how Regulatory decisions can affect developers, conservationists, and the general public. Her ability to communicate effectively with applicants, the public, federal, state and local agencies, and peers in the regulatory community has led to productive collaborative approaches in resolution of complex regulatory issues.
