♦ ERC Aquatic Resource <br /> Pit Project Site <br /> Delineation Report <br /> February 17,2023 <br /> ;W <br /> x, <br /> Photo 11. Overview facing west of Aquatic Resource C, a Photo 12. Overview facing east of Aquatic Resource C, a <br /> topographical depression,within a ditch in the southern portion topographical depression within a ditch in the southern <br /> of the survey area.This ditch and topographical depression are portion of the survey area. Broad leaf cattail dominates with <br /> likely filled with irrigation water during the growing season. a ruderal upland herbaceous understory. <br /> AQUATIC RESOURCE D (0.005 ACRES) <br /> Aquatic Resources D is a topographical depression in the southeast corner of the survey area. The <br /> topographical depression contains a palustrine emergent nonpersistent seasonally flooded (PEM1A) <br /> wetland habitat. The topographical depression is surrounded by higher elevation upland habitat and <br /> bound to the north, east, south and west. It appears hydrology within the topographical depression is <br /> primarily supported by surface water run-off as well as irrigation run-off from the agricultural field within <br /> the survey area.A direct surface water connection to other Waters of the U.S.was not observed. <br /> The topographical depression was delineated based on the presence of hydrophytic vegetation, hydric <br /> soils, and indicators of hydrology. <br /> The vegetation within the topographical depression contains broad leaf cattail (Typha latifolio), reed <br /> canary grass (Phalaris arundinoceo) and smooth brome. The dominate species within the topographical <br /> depression consist of hydrophytic species (FAC-FACW). <br /> Soils within the topographical depression are generally sandy loam in texture, meeting the criteria for <br /> hydric soil indicator F8 (Redox Depressions). At the time of the delineation, primary wetland hydrology <br /> indicator C3 (Oxidized Rhizospheres on Living Roots) was observed within the topographical depression. <br /> Additionally, secondary hydrology indicators included D2 (Geomorphic Position). <br /> Aquatic Resource D comprises a total of 0.005-acre within the survey area (Appendix A).
