EJNNER DATE <br />COLORADO FIELD SUPERVISOR <br />Re: Threatened and Endangered Species Habitat Assessment — The Hatchery Pit <br />Dear Ms. Linner: <br />Fiore and Sons is proposing development of a parcel of property in Commerce City, <br />Colorado near the intersection of 88`h Street and Monaco Street (study area). In <br />anticipation of potential federal actions such as Federal Emergency Management <br />Agency approval for floodplain mapping, Fiore and Sons retained ERO Resources <br />Corporation (ERO) to evaluate the project for potential effects on species listed as <br />threatened or endangered under the Endangered Species Act (ESA). <br />Project Location <br />The study area is in Section 20, Township 2 South, Range 67 West of the 6th Principal <br />Meridian in Adams County, Colorado (Figure 1). The UTM coordinates of the <br />approximate center of the study area are 507157mE, 4412226mN, Zone 13. The <br />latitude /longitude of the study area is 39.860037 °N, - 104.916320 °W. The elevation of <br />the study area is about 5,100 feet above sea level. <br />Site Description <br />The study area consists of a former state fish hatchery and a graded lot in Commerce <br />City, Colorado (Figures I and 2). The eastern half of the parcel is a graded upland lot <br />inhabited by prairie dogs. The vegetation in this area is dominated by golden <br />crownbeard (Verbesina encelioides) (Photo 1). The western half is characterized by <br />ditches, irrigation canals, and a large pond, many of which were used for rearing fish. <br />The vegetation in this area is dominated by smooth brome (Bromus inermis), teasel <br />(Dipsacus fillonum), and musk thistle (Ca)duirs nutans) in the uplands and narrowleaf <br />cattail (Tvpha angunyblia) in the wetlands (Figure 2; Photo 2). The overstory <br />consists of plains cottonwood (Populus deltoides ssp. monilifera) and siberan elm <br />(Ulmus pumila). Other species include field bindweed (Convolvulus arvensis), prickly <br />lettuce (Lacluca serdola), Russian olive (Elaeagnus angustifolia), and diffuse <br />knapweed (Centairrea diffusa). <br />Consultants In <br />Natural Resources <br />and :he Environment <br />
