also developed a steady-state flow model and evaluated fluid transient potential for a multi-well pumping system. From this work, it was determined that significant additional sources of water would be needed to supply the plant with the water needed for its processes. Following that first phase ofthe project, we worked with MCP to connect a number of existing remote wells to the plant via an II-mile-Iong pipeline that ran through undeveloped agricultural areas outside of the city of Marshall. We also helped size the well pumps to work together and supply the plant with wa- ter, and evaluated design alternatives to reduce or avoid the possibility of pressure surges that are com- mon in such systems. Part of this work included obtaining permits from the Department of Natural Re- sources to cross the Redwood River and other protected waters of the state. Due to the fast-track nature of the project, we worked with the contractor to implement construction techniques that allowed the DNR to approve the protected-waters crossing permit very quickly. In addition, we worked with the U.S. Army Corps of Engineers to obtain permission to install several miles of pipeline on land that was part of an existing flood diversion project constructed by the Corps to protect the city of Marshall. This work was also conducted on a fast-track basis; Corps approval was obtained in a matter of weeks, instead ofthe months such approval usually requires. Surface Water and Natural Resources Employing team members with complimentary areas of expertise, Barr has conducted numerous natural resource inventory surveys. Barr staff boasts both training and experience in employing Minnesota Land Cover Classification Surveys (MLCCS), and we have spent countless hours in metro area prairies, wet- lands, woodlands, and forests, identiIying plants, assessing community conditions, and noting the degree of non-native plant invasion. For over two decades, Barr's wetland specialists have worked with cities and counties, watershed dis- tricts, private businesses, and industry on wetland identification, delineation, characterization, and map- ping through hydraulic and hydrologic modeling; function and value assessment; planning, protection, and management, including erosion control; permitting assistance; regulatory negotiations; restoration, mitigation and banking; mitigation monitoring and reporting; and historical wetland surveys. Barr has also provided comprehensive stormwater services for municipalities, watershed districts, and industries. We have designed culvert systems, storm sewers, detention basins, and water quality ponds, and developed stormwater non-degradation plans, storm water pollution prevention plans, and comprehen- sive surface water management plans, along with total maximum daily load (TMDL) studies. Barr has also designed a number of alternative stormwater solutions, including the development of rainwater gar- dens and porous parking lots. Barr routinely employs Arc View GIS to manage, interpret, and present a wide variety of data, including ArcllNFO coverage, relational databases, images, global positioning system (GPS), and ASCII data. We have used ArcCAD to develop GIS coverage for wetlands, land uses, soils, and surface-water divides for water resources projects and have developed interfaces that allow the use of ArcCad for pre- and post- processing for hydrologic and water quality models. Our expertise in GIS allows us to assemble data quickly and accurately, and to manipulate it in ways that allow clear understanding of what's on the ground. Barr Engineering Company Page 18
