r~ <br /> <br />JURISDICTIONAL WETLAND DELINEATION <br />A jurisdictional wetland delineation was undertaken on September 9, 1996 during an <br />on-site investigation of the study area. After reviewing maps and aerial photos of the <br />study area, and talking with Mr. Scott Hoover of B&B Excavating, Mr. Greg Lewicki <br />of Greg Lewicki and Associates, and Ms. Cazol Schmidt, the surface owner, the study <br />area was walked. The areas of interest, for the purposes of the jurisdictional wetland <br />delineation, were the two drainages, Spring Creek and the unnamed drainage, the <br />irrigation ditch on the lower terrace, and the spring on the north face of the terrace <br />slope. These features are further described above. <br />Based on discussions of project scope with the proponent, B&B Excavating, the focus <br />of the jurisdictional wetland delineation would be the unnamed drainage and Spring <br />Creek. Jurisdictional wetlands within the study area would be identified, sampled as <br />necessary, and flagged. The current scope of the project anticipates avoiding the <br />irrigation ditch on the lower terrace, the spring on the north slope of the terrace, and <br />Spring Creek. A sample within the Spring Creek drainage was taken for reference, <br />documentation, and comparison purposes. Ten samples were taken within the unnamed <br />drainage. <br />STUDY l1~THODS <br />Greg C.ewicki and Associates provided Savage and Savage with a general location map. <br />and a specific site development plan which identified and located the study area. Upon <br />arrival at the site, the study area boundaries were walked and the character of the site <br />and study area were established. <br />After establishing the study area boundaries, a jurisdictional wetland survey was <br />conducted. The survey and delineation was conducted in accordance with the <br />requirements of the Corps of Engineers Wetlands Delineation Manual (USAGE, 1987). <br />To determine the areas are subject to Corps jurisdiction, three criteria were evaluated: <br />(1) evidence of a hydrologic regime reflecting saturation or periodic inundation by <br />surface or ground water of sufficient duration and frequency, (2) soils which are <br />considered hydric by classification or field characteristics indicating anaerobic <br />conditions, and (3) a prevalence of vegetation typically adapted to areas of wetland <br />hydrology and soils. <br />At eleven sample points within the study area, the three criteria were evaluated. <br />Dominant individual plant species were identified, and their wetland indicator status <br />was assessed at each sample point (USFWS, 1988). Evidence of the hydrologic regime <br />at the sample point was collected and evaluated. A soil test pit was dug using a bucket <br />auger to the interface of the parent material or 16 inches. Soil horizons were inspected <br />and described using texture, soil color (Munsell, 1992), and moisture. Observations <br />• were recorded on USAGE approved data sheets, and are attached in Appendix 1. <br />-3- <br />
