I I I I I I I I PPROJECT MANAGEMENT PLAN GENERAL INVESTIGATION STUDY CITY OF GREELEY, COLORADO May 2005 1 PROJECT SCOPE The scope of this project includes solving both flood control and ecosystem problems along the Cache la Poudre River at Greeley, The extent of the solutions will be governed by the agreement worked out between the city of Greeley and the Corps of Engineers, 1.1 Location The study area is located in Weld County Colorado, in and around the city of Greeley, The potential study area extends along a 17 mile reach of the Cache la Poudre River, from its confluence with the South Platte River upstream into rural Weld County. The study area is located in Colorado Congressional District 4. The location of Greeley in north-central Colorado and the study reach within Greeley are shown in Figures 1 and 2, I The focus of the flood damage reduction feasibility effort will be on an approximately 7 mile reach of the Cache la Poudre River; Birch Avenue upstream to North 47th Ave, The study effort will be confined to the Cache la Poudre River and its flood plain, Most of the potential flood damages in that reach are concentrated in a 2 mile reach near Highway 85. Residential and industrial areas east of 8'h Avenue have been the most susceptible to flood damage, It is in that area that most of the flood damage reduction feasibility efforts will be concentrated. Ecosystem restoration efforts will be focused on reaches of the river that show the most promise for riparian habitat improvement. The potential for habitat improvement along the river and in off,channel storage areas and abandoned oxbows between the Poudre Learning Center and Island Grove Park were noted for further evaluation in the Reconnaissance Study, That reach will be the initial focus for defining feasible ecosystem restoration efforts, 4
