Seasonal Wetland Habitat

The restoration or construction of wetland habitat to off-set or mitigate unavoidable impacts to wetlands, streams, and other waters of the U.S. is a typical permit requirement of the Clean Water Act for a variety of project types. The restoration or construction of freshwater wetlands, such as vernal pools and seasonal wetlands, replaces lost aquatic resources functions and provides important habitats for support a number of rare or protected plants and animals. Traditional wetland mitigation is done concurrently with project impacts, and may include on-site, off-site, in-kind mitigation, out-of-kind mitigation, or any combination of these. .

As part of the environmental permitting process, ECORP Consulting provides our clients with expertise in developing and implementing wetland restoration or construction to fulfill wetland mitigation obligations of U.S. Army Corps of Engineers permits. We have the appropriate technical background, experience, and knowledge of permit requirements to coordinate with project proponents and regulatory agencies to provide mitigation options that are agreeable to all parties and cost effective to our clients. We are well respected by the staff of local agencies and jurisdictions, and have worked hard to maintain good working relationships. Our team of experts assists our clients with all aspects of the wetland restoration/construction process, including:

  • Providing recommendations on the potential of possible mitigation sites based on biological resources and restoration/construction potential;
  • Conducting feasibility studies and cost assessments of various mitigation properties to assist with mitigation property selection;
  • Conducting the required pre-construction surveys and assessments of the selected mitigation property, including cultural, wetland, and special status species surveys;
  • Development of the wetland restoration/construction design plans;
  • Coordination with contractors and engineers to provide costs and contractor selection during the wetland construction bidding process;
  • Development of the Storm Water Pollution Prevention Plan (SWPPP) for the restoration/construction site; and
  • Development of the short term and long term monitoring plans for the restoration/construction mitigation site, including measures to gauge the success of the restored or created habitat, establishment of a long term funding mechanism for the mitigation site, placement of Conservation easements and/or deed restrictions on the site, and securing a long term preserve manager.

ECORP’s biologists and environmental specialists provide project oversight throughout the wetland construction period, directing field and construction crews, and implementing measures to protect biological and cultural resources that are to be avoided. Once wetland construction is completed, ECORP’s biologists implement the short term success monitoring and reporting to document the successful establishment of desired wetland hydrology, vegetation and animal species. After the completion of the success monitoring, ECORP assists with obtaining regulatory agency sign-off/concurrence that all restoration/creation mitigation obligations have been fulfilled. Once the short term monitoring has been completed, ECORP biologists conduct the long term monitoring of the mitigation site, providing management recommendations for habitat management in compliance with the site’s long term management plan.
