ERC DPG Site Aquatic Resource Delineation Report EXECUTIVE SUMMARY This report summarizes the delineation of aquatic resources completed by Ecological Resource Consultants, Inc. (ERC) for the DPG Site Property (study area). ERC conducted a formal routine onsite delineation of aquatic resources within the approximately 265-acre study area located in unincorporated Weld County, Colorado on April 17, 18, and 19, 2019. A total of 18.37 acres of aquatic resources were identified and mapped within the study area which include: 8.01 acres characterized as PEM wetland habitat, 1.23 acres characterized as PSS wetland habitat, 1.29 acres characterized as PSS/PEM wetland habitat, 1.53 acres characterized as PEM/PFO wetland habitat,5.85 acres (6,186 linear feet)characterized as R2UBG riverine habitat, and 0.46 acre (5,759 linear feet) characterized as R4UBK riverine habitat. All aquatic resources and water features within the study area have been identified herein. The aquatic resource areas were delineated and mapped as A,B,C,D, E, F,G, H, I,and J.Aquatic Resources G, H, I, and J appear to contain a direct surface connection to downstream Waters of the US. Aquatic Resource H includes the stream channel and fringe wetlands associated with the Cache la Poudre River, which flows east into the South Platte River, a traditional navigable water(TNWs), approximately 0.8 mile east of the study area. Aquatic Resource G appears to have a direct surface connection to the Cache la Poudre River outside of the study area to the west approximately 575 feet from the project boundary. Aquatic Resource 1 appears to have a direct surface connection to the South Platte River outside of the study area to the east approximately 325 feet from the project boundary. Aquatic Resource J appears to be an irrigation ditch with a direct.surface connection to the South Platte River outside of the study area to the east approximately 120 feet for the project boundary. Aquatic Resources A, B,C,D, E, and F do not appear to contain a direct surface connection to other downstream wetlands or waters of the US and are surrounded by uplands. Aquatic Resources A and B are manmade remnant reclaimed shallow aggregate pits.
