To quantify what compensatory wetlands mitigation is required for your project, we must determine the value of the wetland by calculating the change in function due to the permitted activity. Functional assessments evaluate current wetland functions and predict potential changes to a wetland’s functions as a result of proposed activities. Wetland function models differ between governing agencies and their district offices. These models generally identify individual functions or a single all-inclusive function.

Example 1:

Function types are classified into three separate credit units by the U.S. Army Corps of Engineers – Galveston District. These categories include:

  • Physical (storage of surface waters)
  • Chemical (removal of elements and compounds)
  • Biological (number and size of trees)

Example 2:

The Louisiana Department of Natural Resources utilizes an all-encompassing “credit acre” that includes all wetland functions in one unit.

Spirit is experienced with conducting several different wetlands function and value models including Hydrogeomorphic (HGM), Wetland Value Assessment (WVA), Wetland Rapid Assessment Procedure (WRAP), Modified Charleston Method (MCM), and other models utilized throughout the U.S. Because of our broad and extensive experience with wetlands modeling we can provide our clients with accurate mitigation projections.
