<br />EXECUTIVE SUMMARY <br />Savage and Savage conducted a jurisdictional wetland delineation March 29 and Apri126, <br />2004 within the boundaries of the Northern Colorado Constructors Inc. Pit #1 extension. <br />The site was evaluated for the three jurisdictional wetland criteria; hydrophytic vegetation, <br />hydric soils, and a hydrologic regime indicative of inundation or saturation. We concluded: <br />• The surface water drainage that starts the west boundary of the site and <br />flows across the northwest coiner of the site (feature D) originates south of <br />the proposed extension site and flows north into the South Platte River. <br />Recently, Terry McKee of the U.S. Army Corps of Engineers inspected the <br />surface water drainage, and concluded that the surface water drainage was <br />jurisdictional as a result of alterations to the drainage. This feature <br />comprises 0. i6 acres wit3rin the project azea. <br />• Wetland depressions A, B, C, E, and F are isolated features that are not <br />adjacent to or connected to a tributary systertL These isolated depressions <br />are located within the north portion of the site. <br />• Feature G is a cattail marsh wetland located at the southwest comer of the <br />®.-=- extension azea and is connected to the surface water drainage discussed <br />f~ above (feature D). The cattail marsh wetland is jurisdictional as a result of <br />its connection to the jurisdictional surface water drainage. The cattail <br />marsh wetland (mcluding the portion of the surface water drainage in this <br />area) comprises 2.75 acres. <br />• Features H and I aze surface swale drainages. These features aze not <br />connected to a trbibutary system and are not adjacent to a trbibutary system. <br />Both of the surface Swale drainages are located east of the cattail. marsh <br />wetland (feature G). <br />IIVTRODUCTION <br />Savage and Savage was contracted by Northern Colorado Conshuctors Inc. to delineate <br />the NCC Pit #1 extension that might contain waters of the United States and wetlands. <br />The extension site contains approximately 70 acres located within a portion of the NE'/. of <br />Section 24 in Township 2 North, Range 67 West of the 6`" Prime Meridian, Weld County, <br />Colorado. The property is bounded on the north by a fence line, east by a portion of an <br />o[d railroad grade and a fence tine, south by a fence line, and west by a fence Line. The <br />~ project site is depicted on the attached general location map. <br />NCC Pit St Eatrnsioa Jurisdictional Wetland Delineation and Determination Page 1 <br />99 <br />
