7i. For all filling activities identified in 7h, describe the source and nature of the fill material, the amount in <br />cubic yards that will be used, and how and where it will be placed into the wetland. lhel <br />NA <br />7j. For all excavating activities identified in 7h, describe the excavation method, type and amount of material in <br />cubic yards you will remove, and where the material will be disposed. h[A] <br />NA <br />Part 8—Waterbodies (other than wetlands): Impacts and Mitigation <br />In Part 8, "waterbodies" refers to non -wetland waterbodies. (See Part 7 for information related to wetlands.) el <br />2 Check here if there are waterbodies on or adjacent to the project area. (If there are none, skip to Part 9.) <br />8a. Describe how the project is designed to avoid and minimize adverse impacts to the aquatic environment. <br />D910 <br />❑ Not applicable <br />system ot excavated irrigation ditches (nonwetland waters) Is located on the project site and one irrigated I c Is <br />located just south of the project area. The field investigation delineated 11,860 lineal feet of ditches within the survey <br />area. Ditch 1 is likely considered jurisdictional because of the perennial flow. Ditches 2 and 4 are potentially jurisdictional <br />because they intersect another jurisdictional feature (wetlands W2 and W3, respectively, which are presumed <br />jurisdictional wetlands) Ditch 12 is potentially jurisdictional as it intersects ditch D1 and wetland W1, a presumed <br />juridictional feature. <br />Limited groundwater monitoring was performed on the site to determine general conditions. Periodic monitoring was <br />conducted throughout the 2019 irrigation season, beginning in early April 2019 before irrigation began in the valley, and <br />concluding in November 2019 after irrigation had been shut off for the season and groundwater levels had a chance to <br />stabilize. Ground water levels varied from an average 8 feet below ground level from mid-October through mid-March to <br />an average 1 foot below ground level during the irrigation season, from April to October. Site irrigation will be <br />discontinued once project construction begins. <br />8b.
