Wetland Monitoring

A required part of any 404/401/Isolated Wetland Permit is post-construction wetland/stream monitoring. Typically, a regulatory agency such as USACE or IDEM, will require a qualified biologist to inspect a mitigation site to determine its success according to criteria set forth in the permit. Monitoring typically involves inspection of the mitigation twice during the growing season and a report due at the end of the year documenting the results of the monitoring events. Wetland monitoring typically lasts for 5 to 10 years, depending on the type and size of the wetland mitigation. After the permitted monitoring period has been reached and the wetland has been deemed to meet or exceed the permit success criteria, CSG will seek to have the permit released by the regulatory agencies.

Monitoring of a wetland typically includes:

  • A site visit detailing the development of the wetland including a discussion of plant life, hydrologic characteristics, soil development and any wildlife observed
  • A site visit in the spring (June) and autumn (October) starting after the first growing season and any additional visits required by the regulatory agencies
  • An annual report detailing the wetland’s status (successful or unsuccessful)
  • A corrective action plan if the wetland is not functioning as expected
  • A letter requesting regulatory release of the permit once the wetland is deemed successful
