2q 1 j 4 Storm Drain Master (Plana Phase 2 1 RFP No. 16-02 � F i" R yrh Mujahid Chandoo, PE i Hydraulic Modeling Mr. Chandoo has experience in the planning and design of various storm water facilities for public and private sector projects. He has been involved in preparation of various master plans within Southern California. He has extensive experience in using advanced hydraulic 1 D/21D modeling for surface and sub -surface flooding analysis for the City of Redlands, World Trade Center in New York City, Coachella Valley Water District (CVWD), and City of La Quinta. Mr. Chandoo also has experience in roadway drainage and has been involved in hydrologic and hydraulic analysis and report preparation, as well as preparation of PS&E. He has recently completed the preparation of drainage PS&E for the Cow Camp Road. His computer modeling background includes the application of the Army Corps of Engineers HEC- RAS (River Analysis System), Stormwater and Wastewater Management Model (XP-SWMM), Watershed Modeling System (WMS) and Advanced Engineering Software (AES) for hydrologic/hydraulic analysis in Southern California. Sediment Transport models include HEC-6T and SAM. Mr. Chandoo uses the Geographical Information System (GIB) hydro applications in most of the hydrology and hydraulics software's. Relevant Experience Includes: Santa Ana Storm Drain Master Plan, Santa Ana, California. City of Santa Ana, Engineer. Responsible for hydrology and hydraulics analysis. Michael Baker provided professional engineering services to update the city's storm drain master plan. The city has an established drainage system with some segments over 50 years old and other segments recently constructed. Michael Baker analyzed the main line drainage system and prepared a hydrology study along with maps for the entire city boundary and for individual sub -areas for 2-, 10-, 25-, and 100-year storm events. The capacity of the existing storm drainage was evaluated to determine system capacity sufficiency using a hydrodynamic hydraulic model. A comprehensive list of needed storm drainage improvements was then generated. Michael Baker performed a hydraulic analysis to size sufficient storm drain lines and provided an ESRI ARCGIS geodatabase of city storm drain facilities, including storm drain pipes, city -owned drainage channels, manholes, catch basins, and culverts. Michael Baker used the Bentley software hydrodynamic hydraulic model CivilStorm, which uses hydrographs with in the hydraulic model to determine adequate pipe sizing. San Diego Creek Master Plan of Drainage, Orange County, California. County of Orange. Engineer. Responsible for updating the hydrology for the entire San Diego Creel< Watershed. This watershed is approximately 76,000 acres which includes fourteen (14) sub - watersheds and sixteen (16) Flood Control detention basins. Tasks included reviewing previous studies for the watershed, verifying stage -storage for the basins and updating the ultimate land use for the entire watershed. The hydrology included developing the 100-year expected value and high - confidence storm analysis per the Orange County Hydrology Manual (OCHM) for 16 concentration points along San Diego Creek. Michael Baker provided engineering services to update and extend the San Diego Creek Master Plan hydrology from the confluence with Peters Canyon Wash to the Upper Newport Bay; a total watershed area of 120 square miles. Michael Baker's services included review and update of the watershed maps, rational method analysis, hydrograph parameter development, hydrograph analysis, and preparation of the master plan report.
