Hydrologic Monitoring Results 2010 Max H dro period (Growing Season 22 -Mar through 8 -Nov, 231 days) 3.3 RESULTS OF HYDROLOGY MONITORING Consecutive The following hydroperiod statistics were calculated for each monitoring station during the Occurrences growing season 1) most consecutive days that the water table was within 12 inches of the Percent of growing Season surface, 2) cumulative number of days that the water table was within 12 inches of the soil - surface, and 3) number of times that the water table rose to within 12 inches of the soil surface 38 (Table 4) Depth of groundwater for each of the monitoring gauges is shown in a graph with i precipitation (Figures 5a -5c) This hydrograph demonstrates the reaction at each monitoring 4 location of the groundwater level to specific rainfall events Raw hydrograph data collected from 18 the monitoring gauges is provided in Appendix C Table 4.

The data collected for the 2010 growing season for this Site indicate that it is performing as described in the Mitigation Plan, with all monitoring stations exceeding the hydrology success criterion. 3.3.1 Site Data Year 3 monitoring demonstrates that most of the Site is functioning as designed, with varying degrees of wetness and saturation across the site. All six automated gauges equaled or exceeded the seven percent hydrologic success criterion. All reference gauges also exceeded the seven percent hydrologic success criterion. Figure 5a.

Thus, all the hydrology monitoring stations meet the hydrologic success criterion for 2010. Greens Cross weather station rainfall data indicates that the 2010 growing season rainfall amounts were normal for most of the growing season, except for April, when rainfall levels were slightly below normal and the following month, May, when rainfall levels were above normal. 4.0 VEGETATION 4.1 VEGETATION SUCCESS CRITERIA Successful establishment of vegetation in wetland restoration and riparian areas will be demonstrated by the survival of 260 planted stems following Year 5 monitoring. The Site must also meet the interim success criterion of the survival of at least 320 planted stems per acre at the end of the Year 3 monitoring period. Up to 20 percent of the Site species composition may be 12 i; Floogie Mitigation Site Annual Monitoring Report for 2010 (Year 3) comprised of non - invasive volunteers Remedial action may be required should volunteers present a problem or exceed 20 percent composition A digital image photo log will be used to subjectively evaluate the restoration Site over time A series of images over the five year monitoring period should demonstrate maturation of planted vegetation and volunteer hydrophytic species 4.2 DESCRIPTION OF SPECIES AND VEGETATION MONITORING ' - Eighteen semi- permanent vegetation sampling plots were established within the planted restoration areas to monitor the success of planted vegetation The wetland vegetation plots are 0 10 acres in size (Plots I through 5), and the riparian vegetation plots are 0 05 acres in size (Plots ( 6 through 18) The vegetation plots are distributed across the site, but the precise location and orientation of the plots was random (see locations on as -built drawings in Appendix A) The plots cover approximately two percent of the restored Site Eight tree species were planted on the Site (Table 6) Table 6.

Sections There should be little change in as -built cross sections Cross sections shall be classified using the Rosgen stream classification method and all monitored cross - sections should fall within the quantitative parameters defined for "E" or "C" type channels • Longitudinal Profiles The longitudinal profiles should show that the bedform features are remaining stable, e g they are not aggrading or degrading Bedforms observed should be consistent with those observed in "E" and "C" type channels • Photo Reference Stations Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation and effectiveness of erosion control measures • Benthic Macroinvertebrates Sampling of benthic macromvertebrates within the restored stream channel shall be conducted in Year 1, Year 3, and Year 5 of post - restoration monitoring 5.2 STREAM MORPHOLOGY MONITORING PLAN The stream monitoring program will be implemented to document system development and progress toward achieving the success criteria The monitoring program will be undertaken for five years, or until the final success criteria are achieved, whichever is longer 5.2.1 Cross Sections Two permanent cross sections will be installed per 1,000 linear feet of stream restoration work, with one located at a riffle and one located at a pool Each cross section will be marked on both banks with permanent pins to establish the exact transect used A common benchmark will be used for cross sections to facilitate easy comparison of year -to -year data The annual cross - section survey will include points measured at all breaks in slope, including top of bank, bankfull, inner berm, edge of water, and thalweg, if the features are present Riffle cross sections will be classified using the Rosgen stream classification system 5.2.2 Longitudinal Profile A longitudinal profile will be measured annually throughout the five -year monitoring period The profile will be measured along a representative length of restored channel Measurements will include thalweg, water surface, bankfull, and top of low bank Each of these measurements will be taken at the head of each feature, for example, shallow, pool, and the max pool depth The survey will be tied to a permanent benchmark 5.2.3 Hydrology The occurrence of bankfull events within the monitoring period will be documented by the use of a crest gauge and photographs The two crest gauges will record the highest watermark between ' site visits, and the gauge will be checked monthly to document high flows Digital images will be 17 Floogie Mitigation Site Annual Monitoring Report for 2010 (Year 3) used to document the occurrence of debris lines and sediment deposition on the floodplain during monitoring site visits In addition, the flow observations will be recorded for the headwater stream restoration These may include wrack lines, direct observations, dye tests, or other direct or indirect observations of flow 5.2.4 Photo Reference Stations Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation and effectiveness of erosion control measures 5.3 STREAM MORPHOLOGY MONITORING RESULTS Table 11 presents stream areas that may require further observation Overall, the channel is stable with a few areas of minor erosion 5.3.1 Hydrology Bankfull events were recorded through the months of February to July (Table 12) The largest stream flow recorded on the upstream crest gauge (CG 1) was 2 10 feet above bankfull elevation The largest stream flow recorded on the downstream crest gauge (CG2) was 2 00 feet above bankfull elevation Flow was observed in both headwater streams during the early 2010 growing season 5.3.2 Cross Sections Year 3 cross section monitoring data for stream stability were collected during August 2010 and compared to baseline data collected in March 2008, as well as Year 1 and Year 2 cross section data (Table 13; Appendix B and E) All monitored cross sections were stable and showed little change in channel dimension between monitoring years Cross Section 15 experienced approximately 1 5 feet of bed loss between As -Built and Year 1 monitoring However, Cross Section 15 has been stable since Year 1 monitoring 5.3.3 Longitudinal Profile A longitudinal profile survey was conducted in Year 3 Coastal plain swamp streams are dynamic in nature, and some channel adjustment is expected Overall, the profile survey indicated little change to channel dimensions (Table 13; Appendix B and E) 18 Floogie Mitigation Site Annual Monitoring Report for 2010 (Year 3) Table 11.
