Wetland Services

Wetlands are sensitive ecological receptors. The frequent presence of water attracts a wide array of biota (plants, animals and microbes). Wetlands provide multiple ecological functions besides habitat value including erosion control, flood protection, and water quality improvement.

Roux Associates' staff of wetland hydrologists, scientists and engineers have successfully designed and implemented various wetland remediation, restoration, and monitoring programs at numerous sites throughout the United States. Roux Associates has the expertise to provide a wide variety of natural wetland consulting services, including the following:

  • Delineation
  • Permitting
  • Assessment
  • Monitoring
  • Remediation
  • Mitigation

Our staff specializes in the management, design, and implementation of wetland mitigation projects, wetland evaluations, ecological assessments and hydrologic studies.

The purpose of a wetland delineation is to identify, define and map the limits of potential jurisdictional wetlands. Wetland boundaries are determined based upon the presence of wetland field indicators and baseline information available including historical aerial photos, topographic maps, soil survey maps and wetland maps.

Wetland assessments are performed when known impacts have occurred to a wetland and when potential wetland exposure routes have been identified based upon preliminary site investigations results. The principal objectives of a wetland assessment are to investigate the nature and extent of site related impacts to the wetlands and to determine an appropriate remedial strategy to mitigate impacts.

The principal objective of wetland monitoring is to determine what affects, if any, operation of site activities (e.g., groundwater remediation systems) have on adjacent wetlands. Wetland monitoring is additionally required following wetland mitigation activities to ensure successful planting and design. Wetland monitoring is generally conducted for a minimum period of two years to provide a technically credible basis for evaluation. Additional time may be required to address climatologic extremes that may occur over the base evaluation period.

Remediation of a wetland environment is required when assessment results indicate contaminant levels are significantly above regulatory criteria, which suggest potential ecological exposure. All wetland remediation projects will eventually require compensatory mitigation for the unavoidable temporary or permanent impacts resulting from contamination and/or construction in the wetland environment. Roux Associates staff specialize in mitigation design including wetland restoration, creation, enhancement, or contribution to a mitigation bank.
