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