<br />GEORGESLOVENSKY <br /> <br />Page 2 <br /> <br />April-May 1999 Storm Characterization and Frequency Analysis (West Side Sanitary Sewer <br />Evaluation) - Colorado Springs Utilities. Revised frequency analyses were carried out for <br />four stream gages incorporating both systematic and historical peak flow data. Measured peak <br />discharge rates were compared to computed gage frequency data, FIS flow-frequency data <br />and other recent hydrologic basin analyses. Rainfall data was obtained from a variety of <br />sources and compared to average April rainfall, NOAA Atlas depth-duration-frequency data <br />and PMP depths from Hydrometeorological Report No. 55A. <br /> <br />Project Engineer - Canon City Hazard Mitigation Grant Application. Project engineer for a <br />study of alternatives to alleviate frequent flooding in the City of Canon City, Colorado <br />resulting from runoff from an undeveloped hogback area on the northwest side of the City. <br />Alternatives were developed for inclusion in a Hazard Mitigation Grant Application to <br />FEMA. <br /> <br />Project Engineer - Town of Georgetown Flood Hazard Mitigation Plan. Project engineer for a <br />study of alternatives to alleviate frequent flooding in the Town of Georgetown, Colorado. <br />Flooding sources consist of Clear Creek and South Clear Creek which confluence near the <br />center of town. Potential alternatives were impacted by the need for sensitivity to the rural <br />and historic character of the town, a limited availability of funds and the presence of many <br />homes and businesses immediately adjacent to the channel banks. <br /> <br />Provo River Restoration Study (Central Utah Water Conservancy District). HEC-2 was used <br />as a design tool to develop several restoration plans for a channelized and levied lO-mile <br />reach of the Provo River in Utah. Primary concerns were fishery re-establishment, impacts to <br />land owners, and returning the river/floodplain system to a natmally functioning state of <br />equilibrium. Cost estimates for three alternatives were developed incorporating earthwork, <br />replacement of water control structures, revegetation and property acquisition. <br /> <br />Storm Drainage Master Plan for Las Vegas, Nevada. Hydrologic watershed modeling using <br />HEC-l. Modeling results were used to size and priOlitize drainage improvements. <br /> <br />Storm Drainage Master Plan for Salt Lake City, Utah. Hydrologic watershed modeling using <br />HEC-l. Modeling results were used to size and prioritize drainage improvements. Project <br />included hydraulic analysis of a system of two connected, off-channel detention basins and a <br />large storm drain discharging to the Jordan River. Hydraulic modeling of the surcharged <br />storm drain was accomplished using HYDRA. Operation of the detention basins was <br />simulated using a spreadsheet based model which utilized a HEC-l generated hydrograph for <br />inflow. <br /> <br />Los Angeles County Drainage Area EIR (Los Angeles County Dept. of Public Works). HEC- <br />l1HEC-5 modeling of the Los Angeles and San Gabriel River watersheds and flood control <br />systems. HEC-l modeling was used to quantify watershed runoff. HEC-5 was subsequently <br />applied to simulate the performance of the system of flood control reservoirs. Modeling <br />results were used to develop alternatives for providing IOO-year flood protection along the <br />Lower Los Angeles River. A high degree of watershed urbanization, limited new detention <br /> <br />"';"ij\ <br />f1r1nl'\ln:;:OI',lIFTr~' \~I,!\Ts:)r.1 l,~~if <br />ll!l,~,,,-- <br />
