Exhibit A <br />Scope of Work <br />City of Pueblo <br />Fountain Creek Bedload/Sediment <br />Collection and Removal Demonstration <br />Project Description <br />The City of Pueblo will be requesting proposals from prequalified contractors to provide <br />engineering and construction services for a bedload/sediment collection and removal <br />demonstration project on Fountain Creek within the City of Pueblo, Colorado (the <br />project). The purpose of this project is to complete planning, design, construction and <br />provide program management services for permitting, bidding and installation of a <br />bedload/sediment collection and removal technology to demonstrate potential benefits to <br />Fountain Creek. <br />This is the second phase of a project to evaluate the success of a bed load sediment <br />collector and removal system placed in Fountain Creek approximately %2-mile upstream <br />of the confluence with the Arkansas River. This project will involve the placement of a <br />proprietary Streamside SystemsOO pre-cast concrete sediment collector within Fountain <br />Creek. The sediment collector will serve as a research tool to gage the transport rates of <br />sediment captured by a large-scale collector, and to verify the system's ability to remove <br />and classify sediment for beneficial re-use. <br />The project will study the benefits a bed load sediment collector system to selectively <br />remove problem sediments and evaluate changes in stream morphology, channel <br />reestablishment, and water quality improvement. The project will assess any changes in <br />the water quality and any reductions in downstream sediment deposition, as well as the <br />creek's ability to manage high-flow conditions (flood control). The project includes <br />monitoring to assess the success of the project in relationship to the removal of <br />contaminants from Fountain Creek, impacts to sediment, and potential benefits in <br />reduction of erosion and the re-establishment of a deeper, more stable thalweg within the <br />creek's main channel. This project will serve as a demonstration project to determine if <br />improvements to the main channel can provide for the more efficient transport of return <br />flows into the Arkansas River and improve and sustain existing wetland communities. <br />Proiect Tasks <br />Task 1— Design & Permitting: Complete design, specifications, and permitting for construction <br />of the bedload sediment removal and collection system demonstration project area. <br />rev. 5/13/2010 Page 1 of 3 <br />
