In the restoration approach to mitigation, the applicant returns a damaged wetland as closely as possible to its original condition. It is impossible to “totally duplicate” a naturally-occurring wetland; however, individual functions and systems may be approximated and restored. Restoration means that the wetland will perform the same physical functions and possess the same biological conditions as existed prior to damage. Perhaps the greatest concern in restoration is long-term success, for while it may be possible to recreate circumstances for a brief period, nature must ultimately take over and continue these functions over time. Other factors to consider in evaluating the potential for restoration include: flood storage and conveyance. Site topography is the critical factor governing a wetland’s flood storage and conveyance functions. It is also the most readily restored. pollution control. Some functions such as sediment trapping may be easily assessed and restored; however, other
