The project will involve development of the site for aggregate extraction with a probable post-mining use as municipal water storage. The Nissen Farms resource site comprises approximately 125 acres contained in the S%2 of Section 12 in TSN, R67W of the 6a' prime meridian in Weld County, Colorado. The property is bounded on the north by the South Platte River and a flood control levee, the east and south by property fence lines, and the west by Weld County Road 58. Currently, the property has several ongoing land uses including a homestead, agriculture (row crops), and oil and gas production. Adjacent land uses include oil and gas production, agriculture, dairies, and grazing. The site is approximately 3.5 miles east of Greeley, Colorado, and immediately east and north of Weld County Road 58. The project site is depicted on the attached general location map. The project site is entirely in agricultural production consisting of corn and oats. An irrigation ditch complex comprises the only surface water drainage feature on the property. Vegetation along the immediate mazgins of the earthen irrigation ditches is comprised of a dense stand of reed canarygrass (Phalaris arundinacea) with scattered individual wild licorice plants (Glycyrrhiza lepidota ). Based on the USFWS November 23, 1992 survey requirements for Spiranthes diluvialis, this site is eligible as it is located within the 100 yeaz floodplain of the South Platte River west of Brush, Colorado in alluvial sandy and gravelly soils. Within the project site, the only azeas potentially requiring a survey aze those areas immediately adjacent to the earthen irrigation ditches. The remaining project site azeas are highly disturbed for row crop agriculture.
