I I I . I . ,. I I I I I . I I I I I I II. CORPORATE QUALIFICATIONS Lidstone & Anderson, Inc. (LA) is uniquely qualified to provide engineering services in support of the Flood Control and Drainage Project Prioritization Analyses for Sterling. LA specializes in all aspects of water resources engineering including surface water and ground water hydrology, channel hydraulics and hydraulic design, master drainage planning, and erosion and sediment transport investigations. Specific corporate experience includes the evaluation and mitigation of storm water management problems, development of stabilization measures to mitigate channel bed and bank erosion as well as the preparation of floodplain management plans. Within the last five years, LA has gained considerable experience with the evaluation of storm water management problems and the preparation of master drainage plans. These projects have been conducted throughout the Front Range of Colorado and in Wyoming including work completed for the Cities of Fort Collins, Aurora, Firestone and Golden, Colorado and Cheyenne, Sheridan and Cokeville, Wyoming. Specifically, we offer an intimate understanding of a well established storm water utility-- in Fort Collins--as well as a working partnership with a less sophisticated storm water management organization--in Greeley. We have been instrumental in the modernization and progress of these two storm water management programs over the last 5 years. The matrix shown in Table 1 summarizes LA's corporate experience in previous related projects. The table indicates the specific analytical and design components relevant to each of the projects listed. Although cost estimating and economic evaluation are not listed in the table, many of these projects included these analyses. Reference is made to the detailed project descriptions included in Appendix A. As indicated, our corporate resume reflects considerable experience on related projects hence making LA especially well qualified to complete the work associated with the Flood Control and Drainage Project Prioritization Analyses. Specific information related to our capabilities for performing the work associated with the proposed project is summarized in the following paragraphs. 2.1 Demonstrated Experience in Storm water Management Plans and Master Drainage Planning LA has extensive experience in flood analysis having applied HEC-l and the Stormwater Management Model (UDSWM2-PC) numerous times to determine flood hydrographs in both undeveloped and urban watersheds throughout the United States. Through the application of these models, the LA staff have gained specialized expertise in the theoretical development of unit hydrographs and design storms and the impacts associated with regional versus on-site 4
