Army Corps of Engineers (ACOE, 1987; 2008) and a search for special -status <br />species and suitable habitat for special -status species (e.g., blue elderberry <br />shrubs, vernal pools). <br />Trees in and near the site were assessed for the potential use by nesting raptors, <br />especially Swainson's hawk (Buteo swainsoni). The grassland areas in the site <br />were searched for burrowing owls (Athene cunicularia) or ground squirrel <br />burrows with evidence of past occupancy. <br />Results <br />GENERAL SETTING: The 23+/- acre project site is in San Joaquin County, <br />California (Figure 1). The site is within an Unnumbered Section within Township <br />1 North, Range 7 East, of the USGS 7.5 -minute Stockton East topographic <br />quadrangle (Figure 2). The site is leveled and is situated at an elevation of <br />approximately 25 feet above mean sea level. <br />The site consists of two fields of disked grassland on either side of Duck Creek, <br />which flows through the site (Figure 3 and photographs in Attachment C). The <br />fields in the site have been historically farmed for several decades in hay and <br />annual crops and are highly disturbed from routine farming activities. There is a <br />short row of ornamental trees along the north edge of the site and a tree north of <br />Duck Creek near Pock Lane. <br />Land uses in this portion of San Joaquin County are primarily residential with <br />smaller parcels used for agricultural purposes and commercial development <br />(Figure 3 and photographs in Attachment C). The north edge of the site is <br />bordered by Loomis Road and Pock Lane borders the east edge of the site. A <br />fallow grassland field borders the south edge of the portion of the site south of <br />Duck Creek. Duck Creek borders the south edge of the remainder of the site and <br />there is a field of irrigated pasture with three large radio towers south of the <br />creek. A ruderal grassland field with a church borders the west edge of the site, <br />3009 Pock Lane: Biology 5 November 24, 2021 <br />
