Abstract

A product of the Hydrogeomorphic (HGM) Wetlands Functional Assessment Program, this document provides the procedural framework for applying the HGM methodology to wetlands. It explains the basis and principals behind the HGM method, describes the HGM wetlands classification system, and gives examples of assessment. It is available to State Departments of Transportation. Other products are being developed by the U.S. Army Corps of Engineers and U.S. Environmental Protection Agency with continued FHWA support, such as regional wetland reference models. See also these products: “Regional Procedures and Scientific Models to Assess Functions of Wetlands” and “A Guidebook for Application of Hydrogeomorphic Assessments to Riverine Wetlands” (both are described in this appendix).

Abstract

The research provides examples of flexible mitigation in the watershed planning context for highway projects. Restoration techniques, administrative processes, institutional relationships through which the restorations were accomplished, and written project case histories will be covered in the final report. The research work was completed in 1998. Publication of the report awaits FHWA review.
