S 2017 Wetland Delineation Report Tucson South Sand and Gravel Mine—Brighton,Colorado 4.1.6 Wetland TM A13-WT Wetland TM-Al3-WT(Wetland A13) is a palustrine emergent wetland located on the west side of the Project. Wetland Al is immediately adjacent to Wetland Al and, like Wetland Al2, appears to be a man-made feature created when an area of upland was excavated approximately 6 feet deep and below the water table. Piles of material nearby were observed indicating the wetland is likely man made. Vegetation in the wetland sample plot was dominated by narrowleaf cattails. Soils in the wetland plot were a sands which qualified for the hydric soil indicator Hydrogen Sulfide Odor (A4). Hydrologic indicators included High Water Table (A2), Saturation (A3), Hydrogen Sulfide Odor (Cl), and FAC-Neutral Test (D5). Wetland A13 is approximately 0.02 acre. The wetland is not likely jurisdictional because there is no clear connectivity to a WOTUS. 4.1.7 Wetland TM A14-WT Wetland TM-A14-WT(Wetland A14) is a palustrine emergent wetland located on the west side of the Project. Wetland A14 is immediately adjacent to Wetland Al and, like Wetland Al appears to be a man-made feature created when an area of upland was excavated approximately 6 feet deep and below the water table. Piles of material nearby were observed indicating the wetland is likely man made. Vegetation in the wetland sample plot is dominated by narrowleaf cattails. Soils in the wetland plot were a sandy clays which qualified for the hydric soil indicator Redox Dark Surface (F6). Hydrologic indicators included High Water Table (A2), Saturation (A3), and FAC- Neutral Test(D5). Wetland A14 is approximately 0.06 acre. The wetland is not likely jurisdictional because there is no clear connectivity to a WOTUS. 4.1.8 Wetland TM A16-WT Wetland TM-Al6-WT(Wetland Al 6) is a palustrine emergent wetland located on the west side of the Project. Wetland A14 appears to be a man-made feature created when an area of upland was excavated approximately 6 feet deep and below the water table. Piles of material nearby were observed indicating the wetland is likely man made. Vegetation in the wetland sample plot was dominated by narrowleaf cattail. Soils in the wetland plot did not meet the criteria for any hydric soil indicator, however Saturation (A3) and Saturation Visible on Aerial Imagery (137) hydrology indicators were observed. Wetland scientists used their best professional judgement to determine that the delineated area is a wetland because hydrophytic vegetation and hydrology indicators were observed and it is very similar to the other wetlands identified in the survey area (Al2, A13, and A14).Wetland Al is approximately 0.19 acre.The wetland is not likely jurisdictional because there is no clear connectivity to a WOTUS.
