Sullivan Property Modified Level 1 Wetland Delineation Report and No-Loss Application 4.2 Wetland Delineation The property was evaluated for wetlands during field observations on September 16, 2016 and January 9, 2017. The landowner sampled soils from the pond bottom on October 3, 2016. One wetland/deepwater habitat was identified and delineated on the property(Figure 6). The following description reflects conditions observed at the times of the field visits. Herbaceous vegetation was actively growing at the time of the field visit on September 16. A property boundary survey prepared by Frank R. Cardarelle Land Survey is included in Appendix B. The one delineated Wetland is a Deepwater habitat with a narrow Type 2 (PEMB) wet meadow and boulder toe fringe. It is located in the eastern part of the property. The wetland/deepwater habitat is classified as a PEMB/L1UB4x (Palustrine, emergent, saturated/Lacustrine, limnetic, unconsolidated bottom, organic, excavated)basin. The L1UB4x part of the basin corresponds to the deepwater habitat and covers about 15,140 square feet(0.3456 acre). The PEMB wet meadow fringe covers about 3,350 square feet(0.0769 acre) and ranges from about 3 to 20 feet wide. The deepwater habitat consists of open water. The wet meadow fringe is dominated by reed canary grass with boulders at the water's edge in some locations. The reed canary grass transitions to open water with steep side slopes. The adjacent upland was dominated by manicured lawn on the northwest and southwest sides of the wetland, and to mixed maple woodland on northeast and southeast sides of the wetland. The wetland boundary corresponded to a rise in elevation and a transition from reed canary grass and open water to upland plant communities with 6 to 12% slopes. This wetland is an excavated depression with no visible inlets or outlets. No other areas with hydrophytic vegetation or wetland hydrology were observed on the site. No other areas were shown as hydric soil on the soil survey or as wetland on the NWI map. Most of the basin is classified as a deepwater habitat because the substrate sample from the wetland center indicated it was excavated to a depth of more than 6.6 feet around the time the house was constructed. T'he landowner, Tim Sullivan, sampled soils of the pond bottom on October 3, 2016. The resulting soil profile is shown in Table 3. The sample was taken in the central part of the pond. At that location, the pond contained about 4 feet of water, underlain by approximately 6 feet of mucky/silty sediment. At a depth of approximately 6 feet, the mucky/silty substrate abruptly transitioned to gleyed blue-gray clay loam. 4
