RESTORATION PLAN Glade Creek Stream Restoration Alleghany ...

7.0 Performance CriteriaAll performance criteria for this project are taken directly from the April 2003 Stream MitigationGuidelines, as adopted by the USACE, EPA, NCWRC and NCDWQ, Monitoring Level 1.7.1 StreamsUpon completion of the project, an as-built survey will be conducted, to document the dimension,pattern and profile of the restored channel. Permanent cross sections will be established with anapproximate frequency of one per 20 bankfull-width lengths. The as-built survey will include photodocumentation at all cross sections and structures, a plan view diagram, a longitudinal profile,vegetation information and a pebble count for at least 6 cross sections. The stream will be resurveyedeach year and the survey data compared to the previous year. Success is defined as thedocumentation of no substantial aggradation or degradation of the channel or banks. Downcutting,deposition, bank erosion and an increase in sands or finer substrate material must be documented forassessment by the regulatory agencies.7.2 VegetationPlant survival will be documented with survival plots and photographs. A minimum of 320 stems peracre must be surviving after year 3, 288 stems per acre after year 4 and 260 stems per acre after fiveyears of monitoring.7.3 Schedule / ReportingMonitoring will be performed each year for 5 years with no less than 2 bankfull events documentedthroughout the period. If less than 2 bankfull events occur, then monitoring will continue until thesecond bankfull event is documented. The bankfull events must occur during separate years. In theevent that the bankfull events do not occur during the five year period, the USACE and NCDWQ, inconsultation with the resource agencies, may determine that further monitoring is not necessary.The CVS-EEP Protocol for Recording Vegetation (Lee, 2007) will be used to document and trackvegetation survival and growth.
