The dominant species identified at the Site were planted stems of silky dogwood (Cornus amomum), American elm (Ulmus americana), green ash (Fraxinus pennsylvanica), overcup oak (Quercus lyrata), cherrybark oak (Quercus pagoda), and swamp chestnut oak (Quercus michauxii), and natural recruits of red maple (Ater rubrum) One vegetation problem area was noted during Year 5 monitoring along the southern perimeter of the Site (see Figure 1) it appears that someone encroached into the easement and cleared some of the vegetation within this area Carolina Silvics replanted the area on December 11, 2012 with 40, 3- gallon sweetbay magnolias (Magnolia virginiana) Twenty cross - sections and longitudinal profiles within five 600 -foot reaches were measured throughout the monitoring period As a whole, monitoring measurements indicate minimal changes in both the longitudinal profile and cross - sections as compared to as -built data The channel geometry compares favorably with the emulated, stable E/C type stream reach as set forth in the detailed mitigation plan and as constructed Current monitoring has demonstrated dimension, pattern, and profile were stable over the course of the monitoring period No stream problem areas were noted during Year 5 (2012) monitoring Two onsite groundwater gauges and one reference groundwater gauge were maintained throughout the monitoring period Groundwater gauge 1 was inundated/saturated within 12 inches of the surface for greater than 12 5 percent of the growing season for three out of the five monitoring years, despite severe drought during the majority of the monitoring period Groundwater gauge 2 made success criteria all five years The reference gauge exhibited a downward trend throughout the 5 year monitoring period ranging from 17 1 percent of the growing season in year two to 3 7 percent of the growing season in year 4 and appears to have malfunctioned measuring 0 days of saturation for the Year 5 (2012) monitoring season No onsite wetland problem areas were noted Goals and Obiectives The primary goals of this stream and wetland restoration project focused on improving water quality, decreasing floodwater levels, and restoring aquatic and riparian habitat These goals were accomplished by • Reducing nonpomt sources of pollution associated with agricultural land uses by providing a forested buffer adjacent to streams to treat surface runoff • Reestablishing stream stability and the capacity to transport watershed flows and sediment loads by restoring stable dimension, pattern, and profile Page 2 of 40 • Promoting floodwater attenuation by,excavating a floodplam at a new bankfull elevation, restoring a secondary, entrenched tributary thereby reducing floodwater velocities within smaller catchment basins, increasing storage capacity for floodwaters within the Site limits, and revegetating floodplams to increase frictional resistance on floodwaters • Improving aquatic habitat by enhancing stream bed variability, restoring a riffle -pool complex, and by incorporating grade control/habitat structures • Providing wildlife habitat including a forested riparian corridor within an area highly dissected by agricultural land uses Primary activities at the Site included 1) stream restoration, 2) wetland restoration, 3) soil scarification, and 4) plant community restoration Table 1 describes the Site restoration structures and objectives, which have provided 5004 Stream Mitigation Units (SMUs) and 5 0 Nonriverme Wetland Mitigation Units (WMUs) • Restored 5004 linear feet of two unnamed tributaries to Contrary Swamp (Northern UT and Southern UT) by constructing moderately sinuous, E -type channels on new location • Restored 5 0 acres of nonriverine wetland within the interstream flat filling ditches, removing elevated spoil, thereby reestablishing historic water table elevations • Reforested approximately 20 05 acres of floodplam, stream bank, upland slopes, and nonriverme wetlands with native forest species Success Criteria Vegetation Success criteria have been established to verify that the vegetation component supports community elements necessary for forest development Success criteria are dependent upon the density and growth of characteristic forest species Additional success criteria are dependent upon density and growth of "Characteristic Tree Species " Characteristic Tree Species include planted species, species identified through inventory of a reference (relatively undisturbed) forest community used to orient the planting plan, and appropriate Schafale and Weakley (1990) community descriptions (Coastal Plain Small Stream Swamp and Nonriverme Wet Hardwoods Forest) All canopy tree species planted and identified in the reference forest will be utilized to define "Characteristic Tree Species" as termed in the success cnteria Success criteria dictate that an average density of 320 stems per acre of Character Tree Species must be surviving in the first three monitoring years Subsequently, 290 Character Tree Species per acre must be surviving in year 4 and 260 Character Tree Species per acre in year 5 Stream Success criteria for stream restoration will include 1) successful classification of the reach as a functioning stream system (Rosgen 1996) and 2) channel variables indicative of a stable stream system The channel configuration will be measured on an annual basis in order to track changes in channel geometry and profile These data will be utilized to determine the success in restoring stream channel stability Specifically, the width-to -depth ratio should characterize an E -type or borderline E -/C -type channel, bank - height ratios indicative of a stable or moderately unstable channel, and minimal changes in cross - sectional area, channel width, and /or bank erosion along the monitoring reach In addition, channel abandonment and/or shoot cutoffs must not occur and sinuosity values must remain relatively constant The field indicator of bankfull will be described in each monitoring year and indicated on a representative channel cross - section figure If the stream channel is down - cutting or the channel width is enlarging due to bank erosion, additional bank or slope stabilization methods will be employed Stream substrate is not expected to coarsen over time, therefore, pebble counts are not proposed as part of the stream success criteria Visual assessment of m- stream structures will be conducted to determine if failure has occurred Failure of a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of the channel around the structure, and/or stream flow beneath the structure Hydrology Target hydrological characteristics include saturation or inundation for at least 12 5 percent of the growing season within Trebloc soils (nonriverme wetlands), during average climatic conditions This value is based on DRAINMOD simulations for 62 years of rainfall data in an old field stage these areas are expected to support hydrophytic vegetation If wetland parameters are marginal a jurisdictional determination will be performed for vegetation and soils in these areas Page 3 of 40 Table 1 Site Restoration Structures and Objectives Restoration Segment/ Reach ID Station Range Restoration Type /Approach* Existing Linear Footage/ Acreage Designed Linear Footage /Acreage SMU/WMUs Northem UT 10 +00 —54+65 Restoration /P11 2700 4,465 4465 Southern UT 10+00— 15 +39 Restoration /Pll 442 539 539 Nonnvenne Wetlands Restoration 50 50 50 Mitigation Unit Summations Stream Non rS_ rverme Well "�-= .tT,° -," C -� —r ;y� /�?�El� i �°a i� =` F } -T 00- (l �� '�^ yl$'�,•- �;3= �..�L — t. ^Ir r S 1 �i'' S `,r . �4= .r >-:-� + rte- rf: -_ _ r'° ._ -

Wetland hydrologic monitoring has shown a trend towards success even in several years of drought conditions Gauge 1 was slightly below success criteria in Year 2010 and 2011 with 118 and 10 2 percent of the growing season These years were characterized by excessive drought, during which the reference gauge also did not meet success Given the drought conditions, the relatively high percentage of the growing season the gauge did make success, along with three successful years out of five, it would appear that this gauge is located in a jurisdictional setting EEP recommends closure of the Brown Marsh Site at 5004 SMUs and 5 WMUs Contingencies No contingencies are recommended for this Site Page 20 of 40 Pre - Construction Photos V-' s-� r; Page 21 of 40 mamamea.
