Site Feasibility Studies

WEG utilizes its talented staff and experience to evaluate sites suitable for stream restoration.  Parameters identified during the cursory review include streambank soil texture, bedload, flow regime, channel slope, buffer vegetation, and existing wetlands.  Also documented during the initial phase of study are potential constraints such as utilities, shallow bedrock, current and/or adjacent land use, and access.  Our experienced field team documents all aspects of the feasibility review process such that strategic, cost-effective decisions are realized throughout the selection, design, and implementation phases.

Stream Assessment / Classification

WEG planners, engineers, and ecologists utilize the site feasibility data to develop conceptual and preliminary plans, which allow us to facilitate discussions and obtain approvals from the appropriate regulatory agencies early in the development process.  We apply numerous stream habitat and classification procedures as part of the overall stream restoration process.  These procedures, in part, include Rosgen classification Level I-IV, the Natural resource Conservation Service's (NRCS) Stream Visual Assessment Protocol, and the Environmental Protection Agency's and North Carolina Department of Health, Environment, and Natural Resources' (NCDHENR) Rapid Bioassessment Protocols for macroinvertebrate sampling.  Our staff has conducted numerous benthic macroinvertebrate studies throughout a range of flow regimes and aquatic habitats.

Detailed Stream Restoration Plans

WEG's team of professionals assembles detailed construction documents that incorporate all facets of the design process including local, state, and federal agency requirements.  We conduct the necessary hydraulic/hydrologic modeling that incorporates bankfull width, depth, channel and bank slope, and flow velocity to identify the most appropriate restoration technique.  WEG's experience completing work throughout the mid-Atlantic region facilitates timely plan review and implementation and allows the most appropriate, cost-effective solution to be determined.  WEG also assembles bid packages that include contract specifications, bid schedules, quantities, and design information, and works closely with the selected contractor to ensure that the plans are built to specification.

Construction Monitoring

WEG hydrologists and engineers complete construction monitoring which ensures that construction is completed according to the design plans.  In addition, post-construction monitoring efforts focus on the restored stream channel system, survival of riparian plantings, and water quality and habitat benefits derived from the project.  Monitoring efforts are summarized in a bound report and are in accordance with permit compliance.
