JEFF A. JOHNSON, P.E. <br /> Civil Engineer <br /> Education: <br /> Bachelor of Civil Engineering (BCE) ' - University of Minnesota <br /> Civil Highway Technician St. Paul Technical Vocational <br /> Institute <br /> r - <br /> Professional Registration: <br /> Registered Professional Engineer in Minnesota and Wisconsin <br /> Land Surveyor in Training ( LSIT) in Minnesota <br /> i <br /> j Professional Associations: <br /> Minnesota Society of Professional Engineers <br /> National Society of Professional Engineers <br /> Minnesota Surveyors and Engineers Society <br /> Minnesota Land Surveyors Association <br /> Licensed Minnesota Vocational Instructor <br /> General Background: <br /> Managed design teams on hydrologic analysis of watersheds for <br /> comprehensive storm water management plans. Experienced in <br /> determination of flood frequencies and flows based on specific <br /> • gauge data and general precipitation maps and using this data to <br /> design storm water detention basins, outlet structures and size <br /> bridge waterway openings. Proficient in SCS and the U. S.G. S. <br /> methods of determining. runoff and in the use of the SCS TR-20 <br /> computer model for a watershed analysis. Experience includes use <br /> of the Army Corps of Engineers HEC hydraulic computer program <br /> series, extensive use of the HEC-2 model in determining water <br /> surface profiles in channels for flood insurance studies and <br /> bridge sizing and sizing over 70 bridges for hydraulic efficiency <br /> using the Bureau of Public Roads HOBCW computer program. <br /> Experience: <br /> i Project Engineer for Wausau, Wisconsin Comprehensive Storm Water <br /> Management Plan Responsible for hydrologic modeling of large <br /> rural and urban watersheds using the SCS TR-20 computer program. <br /> Results of existing conditions were calibrated to historical and <br /> observed conditions. The study included analysis of ultimate <br /> development, and recommendations for future detention areas and <br /> volumes, and . for future ditch and trunk storm sewer system <br /> improvements. <br /> Design. Engineer for Dunkirk Lane Drainage Study . - Plymouth, <br /> Minnesota Design engineer in the hydrologic and hydraulic <br /> modeling of an urban drainage system with numerous basins. The <br /> SCS TR-20 computer model was used to develop runoff hydrographs <br /> and perform- basin routing. The Army Corp HEC-2 computer model <br /> i � was used to determine water surface profiles in the major ditch <br /> systems. <br />
