Site Feasibility
Studies

WEG staff have conducted wetland mitigation feasibility studies on well over 18,000 acres of land.  WEG brings years of experience and a talented field staff into the procedure of selecting sites suitable for wetland creation, restoration, and/or enhancement.  Important factors include soil quality, availability hydrology, slope analysis, excavation requirements, existing wetlands, and potential constraints such as utilities, shallow bedrock, current and adjacent land use, access, and public opinion.  Our ecologists and environmental planners are trained in rapid assessment techniques, utilizing off-site resources (i.e., GIS, aerial surveys, color infrareds, soil surveys, etc.) to quickly evaluate potential mitigation sites worthy of additional on-site investigation.  WEG's field team documents all aspects of the feasibility review process, including detailed soil borings with texture and fertility analyses, topographical surveys, detailed groundwater monitoring studies, and detailed wetland delineations.

Conceptual and Preliminary Designs

WEG planners, engineers, and ecologists utilize the site feasibility data to develop conceptual and preliminary plans, which allows us to facilitate discussions and obtain approvals from the appropriate regulatory agencies early in the development process.  We provide an overall master plan, water budget analysis, grading, cross-sections, and notes and details in a bound set of documents to the agencies that demonstrate how the site will function hydrologically, as well as the inherent habitat and water quality benefits derived from the wetland mitigation project.

Monitoring

Construction monitoring is critical to determining the success of the wetland mitigation project.  WEG engineers provide routine site inspections to ensure that the plans are built to specification as well as provide continual support and direction throughout the construction phase.  In addition, our ecologists work with staff hydrologists, planners, and engineers to quantify the parameters typically used in mitigation performance monitoring - vegetation, hydrology, and often soils.  Staff technicians and hydrologists conduct detailed groundwater monitoring studies during the growing season, and our  soil scientists sample and interpret the shallow soil profile.

Detailed Wetland Construction Documents

WEG's team of professionals assembles detailed construction documents that are in biddable format for contractors.  The construction documents incorporate all necessary erosion and sedimentation control measures such that all local, state, and federal requirements are satisfied.  Our vast experience in completing work throughout the mid-Atlantic region facilitates timely, cost-effective plan review and implementation.  Once the mitigation site has been constructed, WEG works closely with the selected contractor to ensure that the plans are built to specification.
