INTRODUCTION <br />Savage and Savage conducted a jurisdictional wetland delineation within the Arends, <br />Reinoehl, and Archuleta site for Ready Mixed Concrete Company on September 14, <br />2007. The proposed development site is located west of the intersection of Brighton <br />Road and 144' Avenue in Adams County, Colorado (Figures 1. and 2.). From Denver, <br />the site is accessed by traveling north on U.S. Highway 85 to 144' Avenue, west on 144th <br />Avenue to Brighton Road, and north on Brighton Road to the Boral Brighton Quarry. <br />The proposed development site is accessed from the quarry. The latitude of the center of <br />project site is 39° 57' 30" degrees North with a corresponding longitude of 104° 50' 39" <br />degrees West. The average elevation of the project site is 4990 feet. The site lies within <br />portions of Sections 13, 14, 23, and 24, Township 1 South, Range 67 West of the 6th <br />Prime Meridian, Adams County, Colorado. <br />STUDY NT IETHODS <br />A jurisdictional wetland delineation was conducted within the Arends, Reinoehl, and <br />Archuleta parcels in accordance with the requirements of the U.S. Army Corps of <br />Engineers Wetlands Delineation Manual (USACE, 1987). To determine the areas subject <br />to Corps jurisdiction, three criteria were evaluated: (1) evidence of a hydrologic regime <br />reflecting saturation or periodic inundation by surface or ground water of sufficient <br />duration and frequency, (2) soils which are considered hydric by classification or field <br />characteristics indicating anaerobic conditions, and (3) a prevalence of vegetation <br />typically adapted to areas of wetland hydrology and soils. <br />At five sample points within potential wetland areas the three wetland criteria were <br />evaluated. Dominant individual plant species were identified, and their wetland indicator <br />status was assessed (USFWS, 1988). Evidence of the hydrologic regime was collected <br />and evaluated. A soil test pit was dug using a core auger to 18 inches at each sample <br />point. Soil horizons were inspected and described using texture, soil color (Munsell, <br />Ready Mixed Concrete - Arends, Reinoehl, and Archuleta Site Page 1 <br />Wetland Delineation
