of the analysis to modify the project grading to provide surface storage capacity at acceptable depths which eliminated the City's need to upgrade the existing downstream storm drain system. RBF and its team members are using EPA's SWMM program for a wide variety of unique and complex drainage projects for hydrology, hydraulics, flood routing, storm drain sizing, floodplain mapping, and coupled 1- and 2- dimensional modeling including: • Southern California Logistic Airport (SCLA) Drainage Master Plan (Victorville) — Backbone storm drain system design, SWMM hydrodynamic models were used to minimize pipe sizes for this high desert area with flashy, short -duration storm events. The results of the analysis were compared with a separate WSPG analysis and design, and saved the City over $2,000,000 in storm drain improvements (approximately 25-30% savings). • City of Anaheim Floodplain Revisions— RBF is using SWMM in conjunction with HEC -RAS to prepare updated floodplain mapping for a unique channel overflow situation in the city. SWMM is being used as a coupled 1D/2D model to analyze overflow to this existing urban area from a regional flood control channel which was modeled using HEC -RAS. Detailed 2D modeling of the overflow flood hydrograph using the existing storm drain system and surface flow resulted in the removal of over 50 structures for the current effective floodplain. ■ Oak Glen Storm Water Detention Basin (Yucaipa) — Complicated regional flood control basin included one flow-through and two flow -by storage areas connected via culverts and overflow weir sections. SWMM was used to effectively model the complex hydraulics to better define the basin performance and determine the flood attenuation provided by the basin. The results of the flood routing analysis were used to update regional hydrology prepared using the local methodology. ■ Naval Training Center / Liberty Station Redevelopment (San Diego / Point Loma) — SWMM model used for preparation of hydrology and hydraulic modeling for master plan development. The project is located on Mission Bay, and the SWMM analysis reviewed various tidal elevations and the impacts on the system performance. ■ Master Drainage Plans for the Cities of Buena Park, Anaheim, Brisbane, Thermalito, Fort Ord redevelopment, and Lathrop - SWMM model was used for preparation of hydrology and hydraulic modeling and pump station and storm drain facility sizing in support of numerous storm drain master plan projects throughout California. City of Santa Ana and Agency Experience RBF has extensive experience in the planning, design, and construction of numerous large public works projects with Federal, State, local, and regulatory agencies. Few consulting firms can match our range of experience, and clients draw from our insight to ensure change and build the business and technology systems required to effectively and efficiently offer the services citizens demand and deserve. RBF has an excellent working relationship with the City of Santa Ana and has worked on several projects over the years. The letter of reference to the right illustrates the commitment our staff has provided on past projects. As the City contemplates a potential engineering consultant to partner with on this important project, RBF anticipates it will carefully consider the qualifications of the outstanding, experienced and knowledgeable personnel that we have ready to commit to provide the critical engineering support desired for the Storm Drain Master Plan.
