decades. The site vegetated with upland grasses and weeds, with soils <br />that appear well draining. <br />• Drainage patterns apparent on historical topographic maps and aerial <br />photographs suggest Bieghle Drain is a realigned ephemeral creek. <br />Bieghle Drain is a potentially jurisdictional Waters of the U.S. due to its <br />tributary relationship to the San Joaquin River. <br />• The jurisdictional status of Bieghle Drain is unknown and would only be <br />relevant if the project will result in impacts to the drain, which seems <br />unlikely. If it is determined there will be work in Bieghle Drain, a wetland <br />delineation would need to be submitted to ACOE for verification to <br />ascertain the jurisdictional status of the drain. <br />• Avoidance of jurisdictional Waters of the U.S. and wetlands and wetlands <br />is recommended, to the maximum extent practicable. If complete <br />avoidance is infeasible, impacts should be minimized to the maximum <br />extent practicable, and permits from ACOE, CDFW, and the Regional <br />Water Quality Control Board (RWQCB) will be then be needed prior to the <br />placement of any fill material (e.g., culverts, fill dirt, rock) within <br />jurisdictional Waters of the U.S. <br />• Due to a lack of suitable habitat, it is unlikely that special -status plants <br />occur in the site. <br />• With the exception of Swainson's hawk, burrowing owl, and white-tailed <br />kite, no special -status wildlife species are expected to occur in the body of <br />the site on more than a very occasional or transitory basis. Swainson's <br />hawk and white-tailed kite could potentially nest in trees in or near the site <br />and may use the grasslands in the site for foraging. Burrowing owls could <br />nest in the site if burrow habitat is available. <br />2706 Pock Lane: Biology 24 November 23, 2021 <br />
