• <br /> l.. <br /> 1 LXLCUTIVL SUMMARY <br /> A jurisdictional wetland delineation was conducted October 1, 2, 5 and November 11, <br /> 1998 by Savage and Savagc within the boundaries of the proposed Kurtz Development <br /> project. The majority of jurisdictional wetlands were found within the northwest <br /> 1 section of the property. A north-south ditch segment within the east quarter of the <br /> properly was later identified as a jurisdictional wetland. The property was evaluated <br /> t for the three criteria for jurisdictional wetlands; hydrophytic vegetation, hydric soils, <br /> and a hydrologic regime indicative of inundation or saturation. Jurisdictional wetlands <br /> were identified and mapped in five locations within the property. Jurisdictional <br /> wetlands and "waters of the United States" were identified within and adjacent to the <br /> Last Chance Ditch in the northeast quarter of Section 29, and within and along the <br /> north-south drainage ditch in Section 28. St. Vrain Creek flows from southwest to <br /> north within the property in Section 29, and is considered "waters of the United <br /> States", with jurisdictional wetlands along its banks. A farm pond adjacent to the <br /> abandoned railroad right-of-way and the Last Chance Ditch contains "waters of the <br /> United States" and jurisdictional wetlands along its edges, both inside and outside the <br /> pond embankment. Jurisdictional wetlands are also found in a mosaic throughout <br /> primary and secondary alluvial terraces above the St. Vrain in Section 29, and are <br /> expressed as wet meadows, predominantly associated with relict oxbows and <br /> microtopographic swales. <br /> INTRODUCTION <br /> Savage and Savage was contracted by Varra Companies to delineate an area thought to <br /> contain jurisdictional wetlands within the boundaries of the Kurtz Development project. <br /> The area of interest is accessed by driving 3.9 miles east of Interstate 25 on Colorado <br /> Highway 66, turning south onto a farm road which forms the boundary between <br /> Sections 28 and 29. The Kurtz development is bounded on the north by Colorado <br /> Highway 66, the cast and south by farm roads, and the west by St. Vrain Creek. The <br /> property is located within the E'/2NE'k of Section 29 and the NW'b and N'/zSW'b of <br /> Section 28, T3N, R67W of the 6th prime meridian in Weld County, Colorado. The <br /> USGS 7.5 minute quadrangle "Gowanda" contains the area of interest. The latitude of <br /> the center of the area of interest is 40'1 P57"N and the longitude of the center of the <br /> area is 104°54'00"W. The UTM coordinates for the center of the area are 4449700mN <br /> and 508480mE. <br /> The purpose of this delineation was to identify and map jurisdictional wetlands and <br /> "waters of the United States" within the area of interest in advance of final planning for <br /> mineral extraction and development of this area. The jurisdictional wetland delineation <br /> was conducted in conjunction with an assessment of habitat for the Preble's meadow <br /> jumping mouse and Utc ladies'-tresses orchid. Fieldwork was conducted October 1, 2, <br /> and 5, 1998 by Michael Savage of Savage and Savagc and November 11, 1998 by <br /> Michael and Edith Savage of Savage and Savage. <br /> -1- <br />
