1 <br /> <br /> <br /> <br />4.3 Map Production <br />Field delineated wetlands were illustrated and recorded on the 1'=200' scale topographic <br />maps (Appendix I - 2 sheets). Wetland surface areas were planimetered direcNy from the <br />maps to determine their size. <br />4.4 Corps of Engineer Field Verification <br /> <br />LJ <br /> <br />LJ <br />1 <br />Mr. Terry Md(ee, Environmental Speaalist with the U.S. Army Corps of Engineers, visited <br />the site on November 10, 1993, to review the updated wetland boundaries. All of his field <br />observations and revisions have been incorporated into the set of final maps contained in <br />Appendix I. A set of the final maps have been forwarded to the Corps' office with a request <br />for a final letter of concurrence. Upon issuance of the Corps' letter, the inventory will be valid <br />for a period of three years. <br />5.0 RESULTS <br />5.1 Wetland Acreage <br />A total of 70.18 acres of wetlands were inventoried within the limits of the project azea (Table <br />1). A total of 34.06 aces occur in the east valley (east of Limestone Ridge), 22.25 in the <br />west valley (west of Limestone Ridge), 10.05 occur along and between the four irrigation ' <br />ditches in the southern portion of the project, and 3.82 occur south of Colorado State <br />Highway 66 and north of the Cement Plant. <br />5.2 Wetland Description <br /> <br />1 <br /> <br /> <br /> <br /> <br />5.2.1 East Valley <br />The majority of the wetlands found within the east valley aze contained within two <br />drainages which flow intermittently from north to south. Wetlands assocated with the <br />easternmost drainage originate downslope of the St.Vrain Supply Canal and cross <br />under County Road 47. Another branch of the drainage continues to the north into <br />the Rabbit Mountain open space area. A number of small impoundments occur along <br />the length of the drainage, presumably to encourage water storage for agricultural <br />use. <br />The second drainage flows west of and parallel to the first. Wetlands associated with <br />the drainage also originate downslope of the St. Vrain Supply Canal. Contribution <br /> <br />
