; - Storm Drain Master Planez <br />RR0 Phase 2 RPP No. 16-02 <br />E. RELEVANT PROJECT EXPERIENCE <br />The following representative projects demonstrate our team's capability working together on similar <br />storm drain master plans, watershed management projects, green initiatives retrofitting, and grant <br />assistance for public funding. <br />Storm Drain Master Plan Update F Santa Ana, CA (2015) <br />Michael Baker analyzed the City's drainage system <br />to ensure consistency and capacity with Orange <br />County requirements and prepared a hydrology <br />study for 2-, 10-, 25-, and 100-year storm events. <br />The capacity of the existing storm drainage was <br />evaluated based on the Orange County design <br />criteria to determine system capacity sufficiency <br />utilizing a CivilStorm hydrodynamic hydraulic model. <br />A comprehensive list of needed storm drainage improvements was then <br />generated. Michael Baker performed a hydraulic analysis to size sufficient <br />storm drain lines based on the hydrology study results. The team also provided <br />an Esri ArcGIS geodatabase of city storm drain facilities, including storm dram <br />pipes, city -owned drainage channels, manholes, catch basins, and culverts <br />Drainage Master Plan I Redlands, CA (2014) <br />Michael Baker has completed a Master Plan of <br />Drainage for the City of Redlands to update <br />their drainage infrastructure and to identify <br />regional drainage solutions to the City's <br />historical flooding issues. The heavily <br />developed and historical downtown portion of <br />Redlands has been plagued by several large <br />flood events over the past few decades, some <br />resulting in more than 3-feet of water. As part of this Drainage Master <br />Plan, a linked 1-dimensional/2-dimensional model was developed using <br />XPSWMM to evaluate surface and subsurface conveyance capacities. <br />This comprehensive model allowed the team to run multiple scenarios <br />rapidly to identify the existing system weaknesses, and to recommend <br />appropriate improvements. A 3-D animation of the results of the flood <br />modeling was prepared to help stakeholders understand the flood hazards <br />and the benefits of the proposed improvements. Michael Baker separated <br />the proposed improvements into a priority ranking system. The City will use <br />this system to identify which facilities to improve first. <br />Highlights: <br />♦ Citywide Santa Ana <br />Storm Drainage Master <br />Plan <br />♦ Hydrologic and <br />Hydraulic Analysis <br />♦ Consistency with <br />Orange County <br />Standards <br />♦ Geodatabase of City <br />Storm Drain Facilities <br />Clty of Sar�tarza; <br />71!1y847`5tiF5 �;: <br />Highlights: <br />♦ Citywide Drainage <br />Master Plan <br />♦ Storm Drain Facility <br />Inventory <br />♦ Hydraulic Analysis <br />using XPSWMM <br />♦ Existing Flood <br />Hazard Mapping <br />♦ Educating <br />Stakeholders using <br />3-d Animation <br />♦ _ Green infrastructure <br />:-wClty oaf Red�tTtis-,� <br />':Mbn`Ey M�rshed F.t <br />`�D9 7$8 7584 at 9 =' <br />The project also included the identification and integration of "green infrastructure" to be incorporated <br />into the master plan. A comprehensive study of the City's drainage areas and land uses was performed <br />to identify potential areas for green initiatives. A series of practical green initiatives were developed and <br />incorporated into the document to provide water quality treatment and surface water capture and <br />recharge opportunities within the City. The master plan was recently endorsed by the City's Public <br />Works Commission and unanimously adopted by the City Council. <br />Pape 115 <br />INTERNATIONAL <br />
